Description

Check valve capable of buffering flow

Technical Field

The utility model belongs to the technical field of pipeline valves, and particularly relates to a check valve capable of buffering flow.

Background

The silent check valve is a valve that automatically opens and closes a valve flap depending on the flow of a medium to prevent the medium from flowing backward, and is also called a check valve, a reverse flow valve, and a back pressure valve. The check valve is an automatic valve, and mainly functions to prevent the reverse flow of a medium, prevent the reverse rotation of a pump and a driving motor, and discharge of a container medium, and is also used for a pipe for supplying an auxiliary system in which the pressure may rise to exceed the system pressure. The check valves may be largely classified into swing check valves (rotating about the center of gravity) and lift check valves (moving along an axis). The action mechanism of the check valve is that the valve clack is opened under the action of fluid pressure flowing in one direction; when the fluid flows in the opposite direction, the valve clack is combined by the fluid pressure and the self weight of the valve clack to act on the valve seat so as to cut off the flow, and the valve is not suitable for media containing solid particles and having higher viscosity. When the check valve in the prior art is used on a pipeline, the flow velocity of a medium is not convenient to adjust, if the flow velocity needs to be adjusted, a flow adjusting part needs to be installed, and the purpose is single.
