As a well-known enterprise in China, Mike Valve Fitting has many years of production experience, among which the check valve is loved and purchased by many customers. It can effectively prevent medium backflow, pump and drive motor reversal, and container medium discharge. Check valve refers to a valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent medium backflow. It is also known as a check valve, one-way valve, backflow valve, and backpressure valve.
A check valve is an automatic valve. Check valves can be divided into three types according to their structure: lift check valves, swing check valves, and butterfly check valves: lift check valves are divided into vertical and horizontal types. Swing check valves are divided into three types: single disc, double disc, and multi disc. The butterfly check valve is a straight through type.
In terms of connection forms, it can be divided into four types: threaded connection, flange connection, welding connection, and clamp connection. Do not allow the check valve to bear weight in the pipeline. Large check valves should be independently supported to prevent them from being affected by the pressure generated by the pipeline system. Pay attention to the direction of medium flow during installation, which should be consistent with the arrow direction marked on the valve body. Lift type vertical disc check valves should be installed on vertical pipelines. The lifting type horizontal disc check valve should be installed on the horizontal pipeline.
