FIELD OF THE DISCLOSURE: The present disclosure generally relates to a regulator for regulating flow of a fluid flowing through a fluid line. Particularly, the present disclosure relates to an Air-filter regulator or a Gas-filter regulator BACKGROUND: Air regulators are generally mounted in an air line for supplying regulated air at constant pressure to the equipment disposed downstream thereof, regardless of variations in flow and upstream pressure, thereby eliminating any damage caused to delicate equipment due to abrupt variations in flow and upstream pressures. Air regulators known in the prior art, fail to handle pressure fluctuations in a wide range, particularly, air regulators known in the prior art can regulate pressures within a narrow range and fail if subjected to pressures outside the pressure range for which they are designed. Mounting such air regulators, may even obstruct the air flow inside the air line and result in pneumatic pressure drop, thereby resulting in a reduced flow rate. Such a pressure drop and reduced flow rate occurring due air regulator disposed along the flow passage / air line may be detrimental for the proper working of a pneumatic system of which the air line is a part. Further, air regulators fail to effectively remove moisture carried in the air line, and accordingly the moisture reaches the equipment disposed downstream of the air filter causing damage there- to. | Accordingly, there is a need for an air filter regulator that can handle a wide [ range of upstream pressures, while still retaining the integrity of the air regulator. Further, there is a need for an air filter regulator that regulates the air flow there-through while still maintaining a desired flow rate there-through. Still further, there is a need for an air filter inbuilt in the regulator that effectively removes moisture carried in the air line. Further, there is need of Pitot tube for getting maximum flow through the Air Filter Regulator. Further, there is a need for an improved pitot tube to be used with the air filter regulator that prevents vibration/noise of a diaphragm due to excess pressure in the underside of the diaphragm. Further, there is a need for an air filter inbuilt in the regulator that prevents damage caused to the equipment disposed downstream of the air filter due to unregulated air reaching such equipment, thereby reducing wear and tear of the equipment and increasing it's operational life. Still further, there is a need for an air filter regulator that may be easily mounted on an air line. Furthermore, there is a need for air filter regulator mounted on an air line that facilitates economical operation of a pneumatic system of which the air line is a part of by minimizing the amount of pressurized air that is wasted.

The present invention discloses a fluid filter regulator, particularly, an air/gas filter regulator made of stainless steel for effectively regulating air/gas pressure in an air/gas line for eliminating damage to equipment disposed downstream thereof by avoiding abrupt variations in flow and upstream pressure. The air/gas filter regulator not only regulates the pressure of the air/gas reaching equipment but also removes moisture, thereby preventing moisture from reaching and damaging the equipment. Figure 1 of the accompanying drawings illustrate an air/gas filter regulator 100 mounted on an air/gas flow line 01 of a pneumatic/gas system 1000. Figure 1 also illustrates solenoid valves 110a and 110b disposed downstream of the air/gas filter regulator 100. The air/gas filter regulator 100 supplies air/gas at constant pressure to the equipment through valves 110a and 110b connecting to the equipment disposed downstream thereof, regardless of variations in flow and upstream pressure, thereby eliminating any damage caused to equipment 110a and 110b due to abrupt variations in flow and upstream pressure. Further, the air/gas filter regulator 100 handles pressures within a wide pressure range, while still maintaining integrity of the air/gas filter regulator 100. The air/gas filter regulator 100 eliminates pneumatic/gas pressure drop occurring in the air/gas flow line 01 due to presence thereof along the air/gas flow line 01 and maintains higher flow rate there-through. Referring to Figure 2a - Figure 2d of the accompanying drawings, different views of the air/gas filter regulator 100 are illustrated. The air/gas filter regulator 100 includes a body 101, a bonnet cover 102, a bowl 103, a body seal 104, a baffle 105, a filter element 106, a valve housing 107, a poppet valve 108, a lip seal 109, a valve spring 110, a circlip 111, a stem 112, a stem seal 113, a retainer 114, a bleed seat 115, an inner spring 116, an outer spring 117, a spring disc 118, a regulator bolt 119, a locknut 120, a pitot tube 121, a diaphragm 122, a spring holder 123, a diaphragm support 124, a drain seal 125, a manual drain 126, a spring washer 127, and a socket head screw 128. The air/gas filter regulator 100 further includes a NPT pressure gauge connection 129, a plurality of mounting holes 130 for facilitating mounting of the air/gas filter regulator 100 on the air/gas flow line 01, and pressure relief connection 131. The plurality of mounting holes 130 configured on the air/gas filter regulator 100 are adapted to facilitate both side mounting of the air/gas filter regulator 100. The air/gas filter regulator 100 further includes a moisture removal arrangement 132 in the form of centrifugal separator, for separation of water droplets from the air/gas carried in the air/gas flow line 01. Most of the elements of the air/gas filter regulator 100 are configured from stainless steel, thereby eliminating chances of rusting thereof, as the elements of the air/gas filter regulator 100 come in contact with water droplets carried by the air/gas flowing through the air/gas flow line 01. As the parts of the air/gas filter regulator 100 are made from stainless steel, the air/gas filter regulator 100 is suitable for wide range of applications, further the use of stainless steel for manufacturing the air/gas filter regulator 100 enhances the service life thereof. More specifically, the complex parts of the air/gas filter regulator 100, like the pitot tube 121 and the moisture removal vanes of the moisture removal arrangement/centrifugal separator 132 are made from stainless steel. Dual springs, i.e. the inner spring 116 and the outer spring 117 are adapted to facilitate wide range of pressure regulation by the air/gas filter regulator 100. The diaphragm 122 used in the air/gas filter regulator 100 is a reinforced rolling diaphragm that imparts compact design to the air/gas filter regulator 100 and increases the flow rate there-through. The diaphragm 122 used in the air/gas filter regulator 100 is more clearly visible in Figure 8 of the accompanying drawings. The air/gas filter regulator 100 further includes modular flow path and a specially designed centrifugal moisture removal arrangement, referred to as centrifugal separator consisting of plurality of equi-spaced vanes. The vanes of the centrifugal separator are inclined at 25° to 35° to horizontal plane for effective moisture removal. Figure 11a - Figure lid illustrates different views of the centrifugal separator in accordance with an embodiment of the present disclosure. Figure 12a - Figure 12d illustrates different views of the centrifugal separator in accordance with another embodiment of the present disclosure. The air/gas filter regulator 100 further includes filter element 106 for entrapping undesired particles carried by the air/gas flowing through the air/gas flow line 01, thereby restraining any damage to equipment 110a and 110b disposed downstream of the air/gas filter regulator 100. The air/gas filter regulator 100 further includes a baffle 105 for breaking vortex in the silent zone. The air/gas filter regulator 100 further includes a moisture removal arrangement 132 that utilizes centrifugal action for separation of water droplets from the air/gas carried in the air/gas flow line. The moisture collected from the air/gas stream by the air/gas filter regulator 100 is drained out there-from via the manual drain 126 configured at an operative bottom of the air/gas filter regulator 100. In accordance with still another embodiment of the present disclosure, an automatic drain can be used for draining the moisture collected from the air/gas stream by the air/gas filter regulator 100 out of the air/gas filter regulator. Figure 3a - Figure 3e illustrates different views of the air/gas filter regulator 100. The air/gas filter regulator 100 includes the NPT pressure gauge connection 129 and the pressure relief connection 131. Figure 4a and Figure 4b illustrates different views of the air/gas filter regulator 100. Figure 5 illustrates sectional view of the air/gas filter regulator 100 depicting the internal details of the air/gas filter regulator 100. Referring to Figure 6 of the accompanying drawings, the moisture removal arrangement 132 is illustrated. The moisture removal arrangement 132 utilizes centrifugal action for separating the water droplets from the air/gas carried in the air/gas flow line 01. Due to centrifugal action the water droplets are thrown outwardly and strike the walls 133, this water is collected in a reservoir 134 from where the water is drained through the manual drain 126. Referring to Figure 7 of the accompanying drawings, the dual spring arrangement that includes the inner spring 116 and the outer spring 117 facilitating wide range of pressure regulation by the air/gas filter regulator 100 is illustrated. The inner spring 116 and the outer spring 117 are with opposite Helix springs. The regulation bolt 119 is having fine pitch threads for facilitating the finer regulation of pressure in the air/gas filter regulator. Figure 8 illustrates a diaphragm 122 and other internal details of the air/gas filter regulator 100. More specifically, Figure 8 illustrates housing with an inlet "I" and an outlet "O" defined there for. The valve disposed within the housing receives unregulated air/gas from the inlet and supplies regulated air/gas to the outlet. Figure 8 illustrates a detailed view depicting the internal details of the air/gas filter regulator 100 with a pitot tube 121 and the molded reinforced diaphragm 122. Figure 9a illustrates a pitot tube 121 in accordance with an embodiment. The Pitot tube 121 senses pressure at outlet and transmit the same to lower side of the diaphragm 122. Diaphragm 122 in turn moves the poppet 108 through Stem 112. This arrangement gives maximum flow. However, the pitot tube 121 illustrated in Figure 9a over senses the back pressure and creates excess pressure in the lower area of diaphragm assembly 122 which causes vibration/noise of the diaphragm assembly 122 while relieving the overpressure through the bleed seat 115. In order to prevent over sensing of the back pressure and vibration/noise of the diaphragm assembly 122 due to excess pressure in the lower area of diaphragm assembly 122, the pitot tube 121 is replaced by an improved pitot tube 121a exhibiting enhanced pressure sensitivity. The improved pitot tube 121a illustrated in Figure 9b has a bore with diameter of the bore reducing from a large diameter at an operative bottom end of the pitot tube disposed in the outlet to a small diameter at an operative top open end of the pitot tube disposed below the underside of the diaphragm. In accordance with an embodiment of the present disclosure, the bore of the pitot tube is a stepped bore instead of a being of uniform diameter. Figure 9b illustrates the pitot tube 121a having stepped bore, with diameter thereof reducing from large diameter at the operative bottom end of the pitot tube to small diameter at the operative top open end of the pitot tube. The pitot tube 121, 121a and 121b is having angled cut section at an operative bottom end thereof. The cut opens the bore of the pitot tube at the operative bottom end in the direction of fluid at the outlet. Such a configuration of the pitot tube 121a enables the pitot tube 121a in correctly sensing the pressure and doesn't create excess pressure at underside of the diaphragm 122, thereby reducing vibration in the diaphragm 122. Further, the improved pitot tube 121a illustrated in Figure 9b eliminates noise. The following tables support the above mentioned observation that with the use of the improved pitot tube 121a illustrated in Figure 9b, the noise is eliminated. More specifically, the following table depicts observations for noise conditions at different inlet pressures and different configurations of the pitot tube for outlet tube of 06 mm, for actuating 30 cm stroke length cylinder: Further, the following table depicts observations for vibration conditions at different inlet pressures, during testing using pitot tube of different diameters rotated 90° to outlet of 6mm tube for testing in case of 0100 X 320 mm stroke length cylinder: Still further, the following table depicts observations for vibration conditions at different inlet pressures, during testing using pitot tube of 2mm diameter facing the outlet of 6mm tube for testing in case of eDIOO X 320 mm stroke length cylinder: Still further, the following table depicts observations for vibration conditions at different inlet pressures, during testing using pitot tube of O 2mm diameter rotated 90 degree to the outlet of 6mm tube for testing in case of 0100 X 320 mm stroke length Joucomatic cylinder: Further, the following table depicts observations for vibration conditions at different inlet pressures; during testing using pitot tube of O 1.6 mm diameter rotated 90° to outlet of 6mm tube for testing in case of 0100 X 320 mm stroke length cylinder: Further, the following table depicts observations for vibration conditions at different inlet pressures; during testing using pitot tube of stepped bore of
