[check valve] basic description

Also known as reverse valve, reverse stop valve, back pressure valve and one-way valve. These valves are automatically turned on and off by the force generated by the flow of the medium in the pipe, which is an automatic valve.

[check valve] working principle

The function of this type of valve is to allow only the medium to flow in one direction, and to prevent direction flow. Normally this valve is operated automatically, and under a fluid pressure that flows in one direction, the disc opens; When the fluid is in the opposite direction, the self - overlapping disc of the fluid pressure and the disc ACTS on the seat, thus cutting off the flow.

[check valve] purpose

The check valve is used for pipeline system. Its main function is to prevent the backflow of the medium, to prevent the pump and its driving machine reversal, as well as the leakage of the medium in the container. Check valves can also be used to give pressure to the auxiliary system that can increase the pressure of the main system to supply the pipeline. Check valves can be applied to the pipes of various media according to the different materials. The check valve is installed on the tube road, which is one of the fluid parts of this complete line. The valve opening process is affected by the transient flow state of its system. In turn, the closing characteristics of the disc also have a role in fluid flow.
