WATER-MOVING COLUMN WITH PRESSURE VALVE Russian patent published in 2019 - IPC F16K1/02 F16K41/04 

FIELD: water supply devices.

SUBSTANCE: invention relates to water supply devices, and more specifically to devices for shutoff of a drain pipe of a water intake column. Water-moving column with pressure valve comprises housing with water-supplying and pouring pipe arranged inside it, having pressure valve at its end, which includes a return spring support connected to the water supply pipe, resting on the valve plate connected to the pouring pipe, the seat body with the internal saddle tangential surface, between which and the valve plate the toroidal resilient seal ring is located, and between the seat housing, the pouring pipe and the spring support there are movable seals, characterized in that the inner saddle tangential surface is inclined at angle of 60–80° to the plane perpendicular to the direction of translational movement of the valve plate. Said technical result is achieved by increasing wear resistance of toroidal sealing ring located between spindle and cover by its axial rotation.

EFFECT: improved reliability of the known device.
