brief introduction
A valve that opens or closes by the flow and force of the medium to prevent reverse flow of the medium is called a check valve. Check valves belong to the category of automatic valves and are mainly used in pipelines where the medium flows in one direction. They only allow the medium to flow in one direction to prevent accidents.
Installation
The installation of check valves should pay attention to the following things
1. Do not let the check valve bear weight in the pipeline. Large check valves should be independently supported to prevent them from being affected by the pressure generated by the piping system.
2. During installation, pay attention to the direction of medium flow, which should be consistent with the arrow direction marked on the valve body.
3. Lift type horizontal disc check valves should be installed on horizontal pipelines.
