Butterfly-type buffer check valve refers to a valve that automatically opens and closes the disc depending on the flow of the medium itself, and is used to prevent the medium from flowing back. It is also called a check valve, one-way valve, reverse flow, and back Pressure Valve. FXーHH47/H47XF/HDH47X butterfly buffer check valve is a kind of automatic valve, its main function is to prevent the back flow of the medium, prevent the pump and the drive motor from reversing, and the discharge of the container medium. Check valves can also be used to supply pipelines for auxiliary systems where the pressure may rise above the system pressure.
FXーHH47/H47XF/HDH47X butterfly buffer check valve is mainly used at the outlet of the water pump of the industrial water supply and sewage treatment plant to prevent the medium in the pipe network from flowing back and automatically eliminate the destructive water hammer, so as to ensure that the pump and pipeline are not damaged. Butterfly-type buffer check valve is mainly composed of valve body, valve clack, buffer device and micro regulating valve. The butterfly buffer check valve has the characteristics of novel structure, small size, small fluid resistance, stable operation, reliable sealing, wear resistance, and good cushioning performance. H47X, HH47X, HH47H, H47XF, HDH47X butterfly buffer check valves are The best product for industrial water and urban sewage.
