VALVE Russian patent published in 2024 - IPC F16K3/02 F16K3/20 

FIELD: machine building.

SUBSTANCE: valve comprising valve body (200), valve plate (420) and drive mechanism (100). Valve body (200) comprises two parallel symmetrical plates (211, 212), in which medium inlet and outlet holes are respectively made; on inner surfaces of two plates (211, 212) of valve body are symmetrically located sealing rings (311, 312), and holes for inlet and outlet of medium in two plates (211, 212) of valve body are completely located in closed along periphery holes of sealing rings (311, 312); valve plate (420) surface is smooth, and when the valve is closed, it is tightly located between sealing rings (311, 312); fastening structures surround the periphery of sealing rings (311, 312) in the radial direction and located on two plates (211, 212) of valve body (200) for pressing two plates (211, 212) of valve body (200) and/or O-rings (311, 312); and fastening structures at least by one part can adjust degree of their pressing in direction perpendicular to surface of valve body (200).

EFFECT: fast, convenient adjustment of sealing rings pressing force or their replacement outside the valve, at the same time inside the valve there will be no leakage.
