Check valve is also called one way valve or backflow preventer valve. Its function is to prevent the medium in the pipeline from flowing back. The bottom valve of the water pump is also classified as a check valve. The opening and closing parts are opened or closed by the medium flow and force to prevent the medium from flowing back. The valve is called the check valve. Check valves belong to the category of automatic valves. Check valves are mainly used for pipelines with one-way flow of media, and only allow media to flow in one direction to prevent accidents.
Industrial check valve can be divided into two kinds of vertical check valve and horizontal check valve.
The swing check valve is divided into three types: single-lobe check valve, double-lobe check valve and multi-lobe check valve.
Wafer check valves are straight-through check valves. The above types of check valves can be with different connections: threaded check valves, flanged check valves and welded check valves.Tri clamp check valve
The installation of the check valve should pay attention to the following matters:
1. Do not make the check valve bear the weight in the pipeline. The large check valve should be independently supported so that it will not be affected by the pressure generated by the piping system. 2. During installation, pay attention to the direction of medium flow and the direction of arrow indicated by the valve body. 3. The spring vertical check valve should be installed on the vertical pipeline. 4. The horizontal type swing check valve should be installed on the horizontal pipeline.
