[001] TECHNICAL FIELD
[002] The present disclosure generally relates to the field of steam systems. Particularly, but not exclusively, the present disclosure relates to a steam system which has ball float steam trap arrangement and more precisely the present disclosure relates to the controller of the ball float steam trap.
[003] BACKGROUND OF THE DISCLOSURE
[004] Discovery of steam and the possibilities of using steam for power generation, made the industrial revolution possible. Learning to harness the potential of steam has contributed immensely to the comforts of the modern world and may be considered as a significant step forward in the development of industrialization. Heat energy converts water to steam. This conversion takes place around 100° C depending upon atmospheric pressure. Steam at this pressure is of very limited industrial use. It is common practice to generate and use steam at higher pressures and temperatures to suit various industrial applications. Enough energy must be added to raise the temperature of the water to the boiling point. Then additional energy addition changes the water to steam, without any further increase in temperature.
[005] When steam is used in the process lines it loses its thermal energy and steam condenses and converts back to the liquid state. This condensed water leads to many problems like heat loss, water hammer, and when steam comes in contact with condensed water its cools rapidly and therefore condensed water has to be drained out of the system.
[006] Steam traps are automatic valves that release condensed steam [condensate] from a steam space while preventing the loss of live steam. Steam traps are generally installed at the transition point of high pressure steam systems and low pressure condensate (water) collection systems. Steam traps are designed to prevent loss of heat energy from the system and at the same time to quickly remove condensate from the high pressure steam system space. A steam trap's objective is

to quickly discharge condensate that has formed in steam distribution lines, steam tracers, and steam-using equipment. A steam trap must also be able to save energy by preventing steam leaks and by discharging non-condensing gases such as air.
[007] Many types of steam traps are classified into different categories based on their construction and operation principles, and there are several different models of steam traps.
[008] The mechanical steam traps work on the difference in density between steam and condensate. It includes free float, lever float, Inverted bucket steam trap. This type of trap continuously discharges large volumes of condensate and is suitable for a wide range of process applications. The thermodynamic steam traps operate on sensing the change in fluid dynamics of steam. This type of trap operates on the difference in velocity or kinetic energy between steam and condensate passing through a fixed or modulating orifice. There are two varieties of thermodynamic steam traps: the thermodynamic disc and piston types. The thermostatic steam traps operate on the principle of difference in temperature of steam and condensate. The condensate cools rapidly due to heat loss to the surrounding and a thermostatic steam trap will open and purge the condensate as the lower temperature is sensed. These include bi-metal, balanced pressure, and expansion thermostatic traps. Thermostatic traps operate by utilizing the difference in temperature between condensate that is close to steam temperature and sub-cooled condensate (or low-temperature air).
[009] A ball float steam trap consists of the closed chamber having float and controller assembly. The controller assembly and float is connected by lever and bracket arrangement. The float movement depends on the condensate in a closed chamber, this float is made up of an airtight hollow metal ball, as condensate such as water or similar liquid increased in a closed chamber, according to buoyancy principle float lifts as condensate increased and float goes down as condensate decreased. Taking advantage of this up and down motion of float, the outlet orifice will be open and close for discharging of condensate.

[010] Ball float type of steam trap installed in the system, at starting of system condensate load is more and it must be quickly removed from the system, single orifice trap is not suitable for such condition, this type of trap will take more time to remove condensate from the system.
[011] Most of the ball float type steam trap having float connected to lever or arm. This arm or lever connected to pivot pin and end of this lever having steel ball which used to open and close the outlet orifice. In this type of construction, orifice and steel ball size changes according to differential pressure, which means the same trap can’t to be used for various differential pressure once it is installed in the system. If system up-gradation is required then this type of trap need to remove and install another steam trap having suitable differential pressure. It increases the cost and maintenance is difficult. This type of construction will not give a solution for various differential pressure requirements.
[012] Thus, ball float steam trap is known in the art. However, such steam traps does not provide the controller assembly having multiple orifices with rotating orifice pins which are connected to a single ball float to discharge the large amount of condensate. Also, the existing steam traps does not disclose the double orifice pins connected to a single float by interlink lever bracket arrangement.
[013] The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the prior art.
[014] OBJECTIVE OF THE INVENTION
[015] Objective of the present invention is to provide a solution of starting phase condensate load, which has two orifices which give almost double discharge than single orifice trap, thereby making system compact and handling more condensate load.
[016] Objective of the present invention is to provide a solution for two orifice pin mounted on a single float, due to this steam trap becomes compact.

[017] Objective of the present invention is to provide a solution for various differential pressure requirements. In the present invention, the orifice pin is a rotating type and mounted on a pivot point, the summation of all resultant forces and pivot is always zero, which means the same size orifice pin can be used for various differential pressure. If the system needs to be upgrading then due to this invention no need to replace the steam trap, the same trap used for various differential pressure.
[018] Objective of the present invention is to provide a compact and maintenance-free controller. Most of the balls float steam trap having float, lever or arm and at the end of the arm having steel ball for opening and closing arrangement. In this invention rotating orifice pin used, there is no spring and complicated arrangement which give maintenance free controller.
[019] Objective of the present invention is to provide an efficient steam trap and reduce system cost and bulky system installation.
[020] SUMMARY OF THE INVENTION
[021] One or more shortcomings of conventional systems are overcome, and additional advantages are provided through a system as claimed in the present disclosure. Additional features and advantages are realized through the techniques of the present disclosure. Other embodiments and aspects of the disclosure are described in detail herein and are considered a part of the claimed disclosure.
[022] The present disclosure relates to a ball float steam trap which comprises a chamber defining a closed space, an inlet means for introducing steam in said space and an outlet means for releasing condensate from said space. A steam trap consists of the closed chamber having float and controller assembly. The controller assembly and float connected by lever and bracket arrangement. This lever bracket is welded to float. The controller assembly has a first inlet pipe having a first orifice

leading to a first orifice outlet for the condensate and a second inlet pipe having a second orifice leading to a second orifice outlet for the condensate.
[023] In the controller assembly, a first orifice pin is adapted in the first inlet pipe to control the opening of the first orifice leading to a first orifice outlet and a second orifice pin is adapted in a second inlet pipe to control the opening of a second orifice leading to a second orifice outlet. The first orifice pin and the second orifice pin is rotating type pin. The first orifice pin is connected to the controller by lever bracket arrangement, this lever bracket is fixed to float. The second orifice is connected to the same lever bracket by using a floating pin arrangement, due to this arrangement both the orifice operates on a single float.
[024] The condensate present in the system line cools steam rapidly, therefore condensate must be quickly removed from the system line. At starting stage quantity of condensate present in a system is a very large amount and a single orifice trap is not able to discharge the condensate quickly from the system. Double orifice steam trap having two orifice pin arrangement and two controller discharge opening which gives an almost double-flow discharge as compared to a single orifice trap.
[025] This controller assembly fitted to the closed chamber, when condensate enter in a closed chamber, due to buoyancy principal float starts lifting, due to lever bracket and floating pin arrangement, two orifice pin starts rotating which opening the discharge port and discharged the condensate.
[026] When float lift by 50% of its travel first orifice pin opens by 60% and the second pin opens by 40%, which gives a combined effect of 100% opening of a single orifice pin.
[027] If condensate load is more, then float lift by 100% of its travel and both the orifice pin open by 100% which gives almost double orifice opening for condensate discharge and condensate discharged quicker than single orifice trap.

[049] FIG.1 shows a full structure of the ball float steam trap 22. The ball float steam trap 22 comprises a cover 1 securely bolted on body 2 by using stud and nut 19 to make the leak tight chamber 23, shown in figure 3 and 4. This creates a confined chamber 23 where condensate or similar fluid enters. The controller assembly is securely bolted on body 2 using stud and nut 18, shown in figure 3 and figure 4. The chamber 23 has an inlet means for introducing steam into the chamber 23. The chamber 23 has an outlet means for discharge of condensate, as particularly seen in figure-1. The inlet means for steam and outlet means for condensate is provided on the body 2, shown in figure-2.
[050] Referring to FIG.1 and 2, in an embodiment of the present disclosure the steam trap 22 consists of at least three valves configured at the top of the steam trap 22. A first inlet isolation valve 4 is configured at an inlet of steam line. The first inlet isolation valve 4 is used to isolate

steam trap 22 from the system. A second bypass valve 3 is configured at the top of the closed chamber 23. The second bypass valve 3 is used for bypassing the system fluid. A third outlet isolation valve 5 is configured at an outlet line. The third outlet isolation valve 5 is used to isolate the system line from a steam trap 22. Further, the steam trap 22 includes the integral filter arrangement 7. The integral filter does not allow any foreign particle or any residual into a closed chamber 23.
[051] Referring to FIG.3 and 4, the steam trap 22 of the present disclosure has a controller assembly. The controller assembly comprises of a controller housing 8, securely bolted by stud and nut 18 on the body 2 of the steam trap. The controller assembly has a first inlet pipe 11a and a second inlet pipe 11 for the condensate. The first inlet pipe 11a has a first orifice leading to a first orifice outlet 20 to discharge the condensate. The second inlet pipe 11 has a second orifice leading to a second orifice outlet 21 to discharge the condensate. In the controller assembly, a first orifice pin 9 is adapted to be received in the first inlet pipe 11a. The first orifice pin 9 is configured to control the opening of the first orifice leading to the first orifice outlet 20. A second orifice pin 10 is adapted to be placed the second inlet pipe 11. The second orifice pin is configured to control the opening of the second orifice leading to the second orifice outlet 21. In an embodiment of the present disclosure, the first orifice pin 9 and the second orifice pin 10 are rotating type pins.
[052] In an embodiment of the present disclosure, the steam trap 22, further includes an arrangement for opening and closing of the orifices. The arrangement for opening and closing of the first orifice and the second orifice consists of a ball float 12. The ball float 12 may be made of metallic material however it is not restricted to the same and can be made of any other material of equal strength and configuration. The ball float 12 is fixed at the end of a pivoted lever bracket 13. The first orifice pin 9 and the second orifice pin 10 are configured to be attached on lever bracket 13 by a washer 16 and split pins 17. In an embodiment of the present disclosure. The lever bracket 13 is securely welded on ball float 12. The second orifice pin 10 is connected to lever bracket 13 by floating pin 14 and bracket 15, shown in figure-4.

[053] Referring to FIG.5, the controller assembly comprises a controller housing 8. The controller housing has the first inlet pipe 11a having the first orifice pin 9 and the second inlet pipe 11 having the second orifice pin 10 to discharge the condensate. The first orifice pin 9 and the second orifice pin 10, this double orifice pin is connected to the ball float 12 by lever bracket 13. When the ball float 12 is not lifted up by the condensate, the first orifice pin 9 and the second orifice pin 10 are in closed state. Referring to figure 5(a), it shows a sectional view of the controller and the rectangular open area of the first orifice outlet 20 and the second orifice outlet 21 provided to discharge the condensate.
[054] Referring to FIG 5(b), a sectional view of the controller and a sectional view of the first orifice pin 9 and the second orifice pin 10 is shown. The ball float 12 is connected to a lever of the lever bracket arrangement 13 by a floating pin 14. The first orifice pin 9 is adapted at the first orifice and the second orifice pin 10 is adapted at the second orifice. The sectional view of the first orifice pin 9 shows the opening for the condensate to discharge from the first orifice outlet 20. The sectional view of the second orifice pin 10 shows the opening for the condensate to discharge from the second orifice outlet 21.
[055] Referring to FIG.6, 6(a), 7, and 7(a), different positions of the ball float 12 are illustrated. Figure 6 shows the position of a ball float when it lifts by 50% of its total travel. In an embodiment, when the ball float 12 lifts by 50% of its total travel, the first orifice pin 9 opens up by 60% and the second orifice pin 10 opens up by 40%. This leads to discharge of the condensate from the first orifice outlet 20 by 60% and the second orifice outlet 21 by 40%. Therefore, the total combined effect will be similar to one full open orifice when ball float 12 at 50% of its total travel.
[056] Referring to FIG.6(a), the ball float 12 is lifted by 50% of its travel. The first orifice pin 9 is rotated and opened by 60%. The second orifice pin 10 rotated and opened by 40%. Therefore, the total combined effect of the first orifice pin 9 and the second orifice pin 10 will be similar to one full open orifice when ball float 12 at 50% of its total travel.

[057] Referring to FIG.7, the ball float 12 is lifted by 100% of its travel. In an embodiment, when the ball float 12 lifts by 100% of its total travel, the first orifice pin 9 opens up by 100% and the second orifice pin 10 opens up by 100%. This leads to discharge of the condensate from the first orifice outlet 20 by 100% and from the second orifice outlet 21 by 100%. Therefore, the total combined effect will be similar to double full open orifice when ball float 12 lifts at 100% of its total travel.
[058] Referring to FIG.7(a), the ball float 12 is lifted by 100%. The first orifice pin 9 is rotated and opened by 100%. The second orifice pin 10 rotated and opened by 100%. Therefore, the total combined effect of the first orifice pin 9 and the second orifice pin 10 will be similar to double full open orifice when ball float 12 lifts at 100% of its total travel.
[059] In working embodiment of the present disclosure, when the condensate increases inside the chamber 23, the ball float 12 starts lifting up due to the buoyancy principle. Similarly, when the condensate decreases inside the chamber 23, the ball float 12 goes down. This up and down motion of the ball float 12 is converted into rotary motion of the first orifice pin 9 and the second orifice pin 10. The ball float 12 is connected to the first orifice pin 9 and the second orifice pin 10 by lever bracket 13. The second orifice pin 10 is connected to lever by one more bracket 15 to a floating pin 14 by the washer 16 and split pins 17. In this special interlink lever bracket arrangement, when the ball float 12 lifts up because of the rising condensate, this up movement also rotates the second orifice pin 10 at the same time when it rotates first orifice pin 9. Therefore, both the orifice pins, the first orifice pin 9 and the second orifice pin 10 is rotated by the up and down movement of single ball float 12. This up movement of the ball float 12 gives rotary motion to the first orifice pin 9 and the second orifice 10. The rotary motion of the first orifice pin 9 provides discharge for the condensate from the steam trap through inlet pipe 11a to the first orifice outlet 20. The rotary motion of the second orifice pin 10 provides discharge for the condensate from the steam trap through inlet pipe 11 to the second orifice outlet 21. This dual orifice gives almost double-flow discharge of the condensate from the steam trap when the condensate load is more.

[060] In another working embodiment of the present disclosure, when the condensate level lowers in the chamber 23, the ball float 12 goes down. This down movement of the ball float 12 is transferred to orifice pin 9 and orifice pin 10 by lever bracket 13. The rotation of the first orifice pin 9 and the second orifice pin 10 closes the discharge of the condensate from the first orifice outlet 20 and the second orifice outlet 21 respectively. This closing of the first orifice pin 9 and the second orifice pin 10 traps the steam inside the chamber 23. This trapped steam again condensate inside the chamber 23 and the ball float 12 starts lifting up as the condensate level increases inside the chamber 23.
