DISTRIBUTING OUTPUT VALVE FOR MEMBRANE PUMP Russian patent published in 2022 - IPC F16K11/48 

FIELD: hydropower engineering; heat power engineering.

SUBSTANCE: distributing output valve for a membrane pump includes a hollow case with two input and one output holes, impact valves rigidly fixed on a rod with rod nuts and resting on support saddles pressed with connecting nuts to the hollow case through stop rings, ball-shaped retainers with springs, pressed with bolts, a drive shaft with supports fixed in a cylindrical clip. The rod is made together with a disc, branch pipes with ball-shaped retainers and pressed springs, rigidity of which is adjusted with bolts, are welded from two sides perpendicularly to the hollow case. Support saddles are made with conical chamfers, impact valves have conical plates, the drive shaft is located in blind and passage supports pressed with end and passage nuts, a lever is engaged with the disc in another plane, a seal is installed between the passage nut and the cylindrical clip, and a nut is located in the end of the drive shaft.

EFFECT: improvement of tightness of valves in a closed state and increase in a speed of valve switch from an open state to the close state.
