Structural characteristics
Appearance and connection
The body shape of the pinch check valve is relatively flat, and it is directly sandwiched between the two pipe flanges by bolts or other connectors. There is no complex external connection structure. This connection method makes it have great advantages in the pipe system where installation space is limited.
Its valve disc is usually located in the center of the body, through the shaft pin and other components connected to the body, can be flexibly opened and closed.Material composition
Body materials are common cast iron, cast steel, stainless steel and so on. The cast iron valve body has low cost, has certain corrosion resistance and strength, and is suitable for general industrial and civil water supply and drainage systems; Cast steel valve body strength is higher, can withstand higher pressure and temperature, often used in some demanding industrial pipelines, such as chemical, petroleum and other fields; The stainless steel valve body has excellent corrosion resistance, especially suitable for food, pharmaceutical and other industries with high health requirements.
The material of the valve disc is matched according to the specific working conditions and the material of the valve body, generally rubber, metal and so on. The rubber valve flap has good sealing performance, can effectively prevent media leakage, and has a certain tolerance to some media containing particles; High strength metal disc, suitable for high temperature, high pressure and high speed fluid applications.
Application scenario
Water supply and drainage system
It is widely used in the water supply and drainage system of buildings, such as the domestic water supply pipeline and sewage drainage pipeline of buildings. In the water supply pipeline, it can prevent the backflow of water and avoid damage to the pipeline and equipment due to water hammer phenomenon; In the drainage pipe, it can prevent the backflow of sewage and maintain the normal operation of the drainage system.
Hvac system
Chilled water, hot water circulation pipe for air conditioning system. In the chilled water system, preventing water backflow can ensure the normal operation of equipment such as chiller; In the hot water system, avoiding the hot water backflow is conducive to maintaining the stability of the water temperature and energy saving of the system.
Industrial piping system
In the fluid transmission pipeline of chemical and petroleum industries, the clamp check valve can prevent the backflow of various chemical raw materials, oil and other media to ensure the safety and continuity of the production process. For example, in the crude oil pipeline of the refinery, the pinch check valve is an important safety device to prevent the backflow of crude oil.
