Check valve, also known as silencing check valve
The soundproof check valve is suitable for water supply and drainage pipelines. The valve disc is guided by the central axis at both ends of the inlet, with flexible opening and closing, and can be installed horizontally or vertically. The valve disc is spring-loaded, and its quick closure can effectively eliminate water hammer, with good sealing performance and no noise during closure. It has the advantages of small size, light weight, low fluid resistance, fatigue resistance, and long service life. Noise reducing check valve refers to a valve that automatically opens and closes the valve disc based on the flow of the medium itself, used to prevent the backflow of the medium. It is also known as a check valve, one-way valve, backflow valve, and back pressure valve. Check valve belongs to an automatic valve, whose main function is to prevent medium backflow, prevent pump and drive motor from reversing, and prevent the release of container medium. Check valves can also be used on pipelines to supply auxiliary systems where the pressure may rise above the system pressure. Check valves can be mainly divided into rotary check valves
Noise reducing check valves are commonly used in water supply and drainage pipelines. The valve disc is guided by the central axis at both ends of the inlet, with flexible opening and closing, and can be installed horizontally or vertically. The valve disc design of the soundproof check valve adopts spring loading, and its quick closing can effectively eliminate water hammer, with good sealing performance and noise free closing.
The function of a silencing check valve is to prevent reverse flow and only allow the medium to flow in one direction. Usually, this type of valve works automatically, and under the pressure of fluid flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the pressure of the fluid and the self weight of the valve disc act on the valve seat, thereby cutting off the flow. Not suitable for media containing solid particles and high viscosity.
