Product details

The fire trench silencing check valve is a specially designed valve mainly used in fire water system to prevent water hammer and eliminate noise. It relies on the flow of the medium itself to automatically open and close the valve disc, preventing the backflow of the medium, protecting the water pump and pipeline system, and achieving the function of automatic closure when the direction of fluid flow changes, effectively preventing the generation of water hammer and noise, and ensuring the safe and stable operation of the pipeline system.

Working principle

The groove valves is made of stainless steel structure as a whole. Its working principle is that when the fluid flows forward, the valve disc is opened by the pressure of the medium; When the medium flows back, the valve disc closes under the action of the reverse pressure of the medium and its own gravity, preventing the reverse flow of the medium. This automatic opening and closing function makes groove silencing check valves play an important role in fluid pipeline systems.

Structural characteristics

Groove silencing check valves are usually composed of main components such as valve body, valve disc, guide device, spring, etc. The valve disc can move up and down along the axis inside the valve body, and the guide device and spring ensure the smooth opening and closing of the valve disc. Valve bodies are usually made of materials such as cast iron, ductile iron, carbon steel, or stainless steel building, which have good sealing performance and corrosion resistance.

Development Trends

With the development of technology, future groove silencing check valve may integrate more intelligent functions, such as monitoring valve status through sensors and making self adjustments to adapt to more complex working environments. At the same time, more environmentally friendly and energy-saving products will emerge to meet the market's demand for green products.
