Silencing check valve working principle
When the medium flows in the specified direction, the medium pressure overcomes the spring preload, pushing the valve open, the medium through the valve; when the medium backflow, the backflow medium pressure and spring preload together, the valve flap quickly closed to prevent the medium backflow, thus preventing water hammer phenomenon, play a role in silencing and protection of piping systems.
Performance characteristics
Good sound deadening effect: through special structural design, such as the use of spring-loaded valve flap, streamlined internal flow path, etc., so that the valve flap in the closing can be fast and smooth action, effectively reduce the water hammer pressure and noise generation, to achieve the function of sound deadening.
Reliable sealing performance: the use of advanced sealing technology and materials, such as O-ring elastic seal and metal hard seal combination of sealing structure, as well as with a conical surface of the valve flap and the line of dense valve seat coincide with the design, to ensure that the valve in the closed state has a good sealing performance, to prevent the leakage of media.
Convenient installation: muffled horizontal check valve can be installed horizontally or vertically, suitable for different piping arrangements, greatly improving the flexibility and convenience of installation.
Long service life: the main parts of the valve are made of high-quality materials with good abrasion resistance and corrosion resistance, and at the same time, the structure is reasonably designed, the valve flap has a short stroke, the impact of closing the valve is small, reducing the wear and tear between the parts, thus extending the service life of the valve.
Fluid resistance is small: streamlined flow path design, making the medium through the valve when the resistance is greatly reduced, reducing the energy loss, improving the operating efficiency of the pipeline system.
