Axial flow check valve,check valve

The opening and closing of the disc is determined by the pressure difference between the inlet and outlet of the valve. When the inlet pressure is large and the outlet pressure circulates the sum of the spring force, the disc opens. As long as there is a pressure difference, the disc is always open, but the opening degree is determined by the size of the pressure difference. When the sum of the outlet pressure and the spring spring force is greater than the inlet pressure difference, the disc is closed and always in the closed state. Since the opening and closing of the valve disc is in a dynamic force balance system, the valve operates in a balanced manner, without noise, and the phenomenon of water hammer is greatly reduced.

Axial flow check valve is widely used in petroleum, chemical industry, electric power, water supply, water supply and drainage and other fields. In petrochemical plants, axial-flow check valves are often used to control the flow direction of chemical fluids to prevent accidents. In addition, the axial flow check valve is also suitable for anti-backflow and hydraulic explosion-proof systems of large pumps, fans, compressors and other equipment. Low fluid resistance: The axial-flow check valve is designed as a streamlined channel with good fluid performance and minimizes flow resistance and pressure. Reliable sealing: Specially designed double sealing valve seat to achieve zero leakage and reliable sealing.
