The valve that opens or closes on its own by the flow and force of the medium to prevent the medium from flowing back is called a check valve. Check valves belong to the category of automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents.
According to the structure of the check valve, it can be divided into three types: lift check valve, swing check valve and butterfly check valve:
1. Lift check valves are divided into two types: vertical and horizontal.
2. The swing check valve is divided into three types: single, double and multiple.
3. The butterfly check valve is a straight-through type.
The above check valves can be divided into four types in connection form: threaded connection, flange connection, welding connection and wafer connection.
