Check valve
refers to the opening and closing parts of the circular disc and by its own weight and media pressure generated action to block the media flow back valve. Automatic valve class, also known as check valve, one-way valve, backflow valve or isolation valve. Disc motion is divided into lifting and swing. Lift check valves are similar in construction to globe valves except for the stem that drives the disc. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). Valve is opened when inlet pressure is greater than the sum of disc weight and flow resistance. On the contrary, the valve is closed when the medium flows back. Swing check valves have a disc that is tilted and rotates on its axis and work in a similar way to lift check valves. Check valves are often used as bottom valves in pumping units to prevent the backflow of water. Check valves are combined with globe valves to provide safety isolation. Disadvantages are large resistance, poor sealing when closing.
Specification
The advantages of PVC check valves include:
1. Strong corrosion resistance: PVC material has excellent corrosion resistance and can resist the corrosion of acid, alkali, salt and other chemical media, so it has a long service life.
2. Good sealing of the valve: PVC check valve has good sealing performance, which can effectively prevent the backflow of the medium and ensure the normal operation of the pipeline.
3. Simple structure: PVC check valve has simple structure, small size, light weight, and is convenient for installation and maintenance.
4. Economical and practical: The price of PVC check valve is relatively low, and it is an economical and practical valve product.
5. Green and environmental protection: PVC material does not contain heavy metals, is not easy to produce harmful substances, and meets environmental protection requirements.
