Abstract
Quarter turn variable flow splitting-diverting Valve."Description. This invention helps to divide/split an incoming single main stream flow of fluids or gases into two streams. The volume of flow through each stream is steplessly variable from zero to maximum flow; cumulative flow from both streams remaining a constant. This is achieved through a Ball other type of special design valve which receives main stream flow through its main port. The Distributor (Ball / Pin type), which is the concentrically mounted, movable part of valve; has three radial apertures, emanating from the gallery "M", one to receive the main stream and other two to discharge the flow split by the by the distributor.

The "Quarter turn variable flow splitter diverting valve" can complete its flow splitting diverting function within 25 degrees of valve handle movement. The valve can be actuated any number of times, and flow diversions from zero to full quantity achieved by turning the valve handle through few degrees. This valve can be easily automated

TITLE OF INVENTION:
"Quarter turn variable flow splitting-diverting Valve."
Description.
This invention helps to divide/split an incoming single main
stream flow of fluids or gases into two streams. The volume of
flow through each stream is steplessly variable from zero to
maximum flow; cumulative flow from both streams remaining
a constant. This is achieved through a Ball other type of special design valve which receives main stream flow through its main port. The Distributor (Ball / Pin type), which is the concentrically mounted, movable part of valve; has three radial apertures, emanating from the gallery "M", one to receive the main stream and other two to discharge the flow split by the by the distributor. The quantities of discharges by two outlet apertures will be determined by the position of the distributor(D)controlled by valve handle. The valve control handle moves the distributor clock wise or anti-clock wise. The "Quarter turn variable flow splitter diverting valve" can complete its flow splitting diverting function within 25 degrees of valve handle movement. The valve can be actuated any number of times, and flow diversions from zero to full quantity achieved by turning the valve handle through few degrees. This valve can be easily automated.

This invention consists of u main body "B"(split or single piece design), a cross section of which is shown in the attached sketch. Body (B) is machined to have three ports "e" "F" & "G" and a central cavity to to receive the distributor "D". The distributor has three radial passages which interconnect at the center of the distributor through a recess in the center which acts as a gallery("M") for receiving the incoming flow. and allowing outgoing flow through passages "ee", "ff', & "gg". The distributor is covered with a standard plastic coating to reduce wear and make reconditioning of the valve easy. A hand Lever is mounted on top of the distributor (D) to enable actuation of the Valve. Distributor internal passages "ee" and "ff' are machined at right angles to each other and emanate from the gallery(M).The third distributor passage "gg" also emanating from the gallery(M), is machined at an angle less than 90 degrees to passage "ff". The passage "cc" on the distributor has a flared opening facing the port "E". This flared/enlarged area (kq) can align with passage "E" which is the entry port of valve body. This enlargement at the end of passage "ee" enables flow from port "E" all the time to passage "ee" when the flow splitting diverting positions of distributor changes during operations of the valve.
3/4
At the starting position (see sketch, view-1) Valve body entry port which is connected to the outside source of liquid or gas, and distributor passage "ee" are aligned fully to allow flow to pass through passage "ee" and gallery "M"; and to passage "ff' for full flow through exit port "F" on the valve body; and not permitting any flow through passage "gg" and "G".
When it is required to reduce, outflow through passage "F", the distributor(D) is rotated clock wise with the help of the control handle by few degrees; which partly closes the aperture of passage "ff due to its leading edge being covered by valve body, and correspondingly opens passage "gg" to passage "G", permitting the flow to be split and diverted through two exit passages.
When it is required to further reduce the outflow through port "F", the distributor is rotated clock wise further with the help of control handle, through few degrees, causing further reduction of outflow aperture area of passage "ff, due to the passage getting partly covered by valve body; and correspondingly causes passage of "gg" to open little more to port "g" causing increased flow through it. Thus the flow gets split by the distributor and diverts through two ports with changed volumes.
4/4.
By continuing to turn the handle clock wise progressively, flow through passage "ff' and port" F" gets progressively diminished to nil flow ,where as passage "gg" increasingly opens out to port "G", progressively increasing the outflow to carry full volume entering entry passage "E". View 2 shows the cross section, when full flow is passing through Port "G". Thus flow can be split in any proportion as required, quickly, by marginal clock wise or anti clockwise movements of the distributor control lever.
By turning the handle by nearly 90 degrees, clock wise from its original position flow through all ports can be fully stopped. By reversing this movement, the distributor will return to various flow sharing positions.
