Description

Hydraulic check valve

Technical Field

The utility model belongs to the technical field of the check valve, especially, relate to a hydraulic check valve.

Background

The ball check valve is a check valve using a ball as a valve clack, and the principle is that under the action of thrust generated by medium flow, the valve clack can roll along a set direction on a slide way in a valve body, so that the effect of opening or closing the valve is realized through the ball valve clack. When the ball-shaped check valve works normally, fluid flows from the inlet side to the outlet side, and when the pressure of the inlet side is lower than that of the outlet side, the valve clack automatically closes under the action of factors such as fluid pressure difference and self gravity to prevent the fluid from flowing backwards. At present, when the ball check valve in the prior art is used, the valve clack can be flushed into the outlet side by fluid at the inlet side, so that the outlet side is blocked, and the delivery of the fluid is seriously influenced. Therefore, there is a need to develop a hydraulic check valve to solve the above problems.
