closing parts are opened or closed by the flow and force of the medium, and its function is to prevent the medium in the pipeline from flowing back .
check valve can be divided into three types according to the structure: lift check valve, swing check valve and butterfly check valve. Lift check valves can be divided into two types: vertical and horizontal; swing check valves are divided into three types: single, double and multiple; butterfly check valves are straight-through. The above-mentioned check valves can be divided into threaded connection, flange connection, wafer type and welding in connection form.
Attention to the installation of H41H-16C carbon steel lift check valve:
1. Do not allow the check valve to bear weight in the pipeline, and the large check valve should be independently supported so that it is not affected by the pressure generated by the pipeline system.
2. When installing, pay attention to the direction of medium flow should be consistent with the direction of the arrow marked on the valve body.
3. Lifting vertical flap check valve should be installed on the vertical pipeline.
4. Lifting horizontal flap check valve should be installed on the horizontal pipeline.
