The check valve is an automatic valve that is used to open when the medium in the pipeline system is flowing forward and close when the medium is flowing backward. wave and reduce damage to the pipeline system.

Check valves can be divided into five categories according to the relative displacement between the closing part and the valve seat: lift, swing, disc, diaphragm and ball check valves.

For the above check valves, most of them have the following disadvantages: "loud noise" and vibration caused by water hammer when closing; due to the vibration of the valve plate, the mechanical friction movement between the shaft and the shaft sleeve of the "joint part" in the valve is generated.

When the vibration frequency of the valve plate is too high, there will be mechanical friction movement between the shaft and the bushing, the valve plate will be displaced, the seal will fail, and sometimes the valve plate will fall off, making the system protection failure; the fluid flow in the valve is disordered, and the flow resistance loss is large. Serious energy loss, etc. In order to avoid and improve the above shortcomings, the spherical check valve has been widely used and popularized for its performance advantages such as good sealing performance and extremely small flow resistance. Independent multi-channel multi-ball" check valve.
