DN50-DN600mm Rubber Disc F6 Check Valve For Water
H44H swing check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve.
The check valve is an automatic valve whose main function is to prevent the backflow of the medium, the reverse rotation of the pump and the driving motor, and the discharge of the medium in the container.
Check valves may also be used on lines supplying auxiliary systems where pressure may rise above system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis)
Main structural features
The swing check valve adopts a built-in rocker arm swing structure. All the opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body. Except for the sealing gasket and sealing ring used in the middle flange, the overall There is no leakage point, eliminating the possibility of valve leakage. The connection between the rocker arm and the disc of the swing check valve adopts a spherical connection structure, so that the disc has a certain degree of freedom in the range of 360 degrees, and has appropriate micro-position compensation. Swing check valves have been widely used in chemical, metallurgy, pharmaceutical and other fields.
The check valve is generally suitable for clean media, and should not be used for media containing solid particles and high viscosity.
