Supply Hebei Huafei grooved silencer check valve

>Hebei Huafei Valve grooved silencer check valve is quick and easy to install, safe and reliable, and is not restricted by the installation site. It is convenient for the maintenance of pipelines and valves. It has vibration and sound insulation and can overcome the problem of pipeline connection within a certain angle range. Coaxiality creates pseudo-differences to solve the thermal expansion and contraction caused by temperature differences.
Silencer check valve refers to a valve that relies on the flow of the medium itself to automatically open and close the valve disc to prevent the medium from flowing back. It is also called a check valve, one-way valve, silencer check 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, prevent the pump and drive motor from reversing, and release the container medium. Check valves may also be used on lines supplying auxiliary systems where the pressure may rise above the system pressure.
The valve disc of the silencer check valve is in the shape of a disk and rotates around the rotating axis of the valve seat channel. Because the channel in the valve is streamlined, the flow resistance is smaller than that of the rising butterfly check valve. It is suitable for low flow rates and unstable flows. It is not suitable for pulsating flow situations with large diameters that change frequently. Its sealing performance is not as good as that of the lifting type. Butterfly check valves are divided into three types: single-disc type, double-disc type and multi-half type. These three forms are mainly divided according to the valve diameter. The purpose is to prevent the medium from weakening the hydraulic impact when it stops flowing or reverses the flow.
Grooved silencer check valves are widely used in pipeline projects such as water supply, drainage, firefighting, air conditioning, gas, petrochemical, water treatment, municipal shipbuilding, etc. to control fluids.
