A check valve is an automatically controlled pipeline valve whose core function is to only allow the medium (liquid, gas, steam) to flow in one direction and prevent it from flowing backward. This protects the safety and stability of the pipeline system, equipment, and process flow.
1.Prevent the medium from flowing backward to avoid equipment damage.
2.Maintain the stable pressure of the system to ensure process continuity.
3.Prevent medium contamination to ensure quality and safety.
4.Simplify system design and replace manual operations.
Check valves are divided into various types according to the different structures of their valve cores, and their applicable scenarios vary. When selecting a check valve, factors such as medium characteristics, pressure and temperature, and installation space should be taken into consideration.
The typical types are as follows:
-Axial flow type -Dual plate type -
Lift type -Swing type -
Tilting disc type As a "basic safety accessory" for pipeline systems, check valves are widely used in almost all fields that require one-way medium flow.
Their core application scenarios include:
-Water treatment industry
-Petrochemical industry
-Energy and power industry
-Machinery manufacturing industry
-Civil field
