Large diameter microresistance slow lockup check valve application
The microresistance slow closing water check valve uses the medium's own pressure to open the valve. When the medium is flowing forward, push the valve disc open to allow the fluid to pass smoothly. In the reverse flow of the medium, the valve disc is closed under the action of the auxiliary closing force such as the medium pressure and its own gravity or spring force, and can realize the slow closing function to effectively prevent the phenomenon of water hammer.
The advantages of this Flanged check valve are obvious. It has low resistance and does not cause excessive pressure loss to the forward flowing fluid, thus reducing energy consumption. Slow closing function can avoid water hammer caused by sudden closure, protect the pipeline system and related equipment. At the same time, the large diameter design can meet the control requirements of large flow fluids.
In practical application scenarios, large-diameter micro-retarded check valves often appear in water supply and drainage systems.(check valve price)
For example, in the water supply network of the city, especially the main water supply pipe of large caliber, to ensure the one-way flow of water and prevent water backflow from affecting the safety of water supply.
In the drainage pipe of the sewage treatment plant, the sewage can be prevented from backflow and avoid damage to the sewage treatment equipment——sewage check valve
In the pump station, when the pump stops working, the valve slowly closes(slow closing check valve)，preventing the powerful water hammer from hitting the pump and piping system.
In the industrial cooling water circulation system, it can ensure the one-way circulation of cooling water, prevent equipment failure caused by countercurrent, and maintain the stable operation of the whole system.
