Check valve manufacturers describe the more common faults

　　Check valve manufacturers describe its role is to prevent the backflow of media in the pipeline. The bottom valve of the pump is also classified as a one-way valve. The opening and closing part is opened or closed through the medium flow and force to prevent the backflow of the medium, which is also called the check valve manufacturer. At the same time, it also belongs to the category of automatic valves, mainly used in pipelines with one-way medium flow, and only allow the medium to flow in one direction to prevent accidents. Usually the fluid under pressure causes the valve disc to open, and flows from the inlet side to the outlet side. The more common faults are:

Check valve manufacturers

1. The valve disc is damaged. 

The way to prevent it is to use a check valve with a ductile material, and the reasons for the media backflow are:

1. The sealing surface is damaged.

2. Contains impurities. Repairing the sealing surface and removing impurities prevents backflow.

The seat of the lift check valve is located on the sealing surface of the seat on the body. In addition to the valve disc that can be lifted and lowered freely, the rest of the valves are like globe valves. Fluid pressure lifts the disc away from the sealing surface of the seat. The media backflow causes the disc to fall back to the seat and cuts off the flow. Depending on the conditions of use, the disc can be of all-metal construction, or it can be in the form of a rubber pad or rubber ring embedded in the disc holder.

The above is the check valve manufacturers tell about the more common failure of the check valve, I hope you can know more about it.
