The main function of check valve is to prevent medium diversion, prevent the reverse of the pump and its driving device, as well as the leakage of the medium in the container, it is also called check valve, check valve.
The opening and closing parts are opened or closed by the flow and force of the medium to prevent the backflow of the medium valve called check valve. The check valve belongs to the automatic valve class, mainly used in the pipeline of one-way flow of medium, only allow the medium to flow in one direction, in order to prevent accidents.
Check valves can be divided into: Swing check valve, lifting check valve, butterfly check valve, air discharge check valve, diaphragm check valve, no wear ball check valve, pipe check valve, slow closed check valve, floating ball fluorine lined plastic check valve, floating ball fluorine lined plastic Y Form silent check valve check valve, high efficiency, basins buffer check valve, swing check valve with pneumatic device, swing check valve with pneumatic closing device, electric hydraulic slowly-closing butterfly check valve, double disc buffer check valve, dual plate check valves for gas, thin shape to the clamp sound check valve, check valve, wafer with minimum flow within the swing check valve, nozzle pressure sealing cover once-through Swing check valve.
Check valve installation should pay attention to the following:
Do not make check valves bear weight in the pipeline. Large check valves should be supported independently, so that they are not affected by the pressure generated by the pipeline.
When installing, pay attention to the direction of the flow of media should be consistent with the direction of the arrow of the valve body;
Lifting vertical flap check valve should be installed in the vertical pipeline;
Elevating horizontal disc check valve should be installed in horizontal pipe.
