A return check valve (also known as a return check valve) is a valve that allows a liquid (usually oil) to flow only one way and stops it from flowing in the opposite direction. It is used in the hydraulic system to prevent the oil from flowing back to the oil tank or oil pump when there is no pressure, so as to protect the system from pollution and damage, and maintain stable operation of the system.
Main functions and principles
One way flow control
The core function of the return check valve is to ensure that the fluid can only pass through the valve from one direction. When the fluid pressure direction changes, the valve will be closed to prevent reverse flow.
protection system
It protects the hydraulic pump and other parts of the system from possible contamination or damage caused by reverse fluid by preventing the return of oil.
Maintaining system stability
In the hydraulic circuit, it helps to maintain the oil pressure and flow state in the system and ensure that the system can work normally and stably.
Application Scenario
Return check valves are widely used in a wide variety of hydraulic and fluid systems and are especially important in the following scenarios:
Hydraulic power system
When the oil pump stops working, prevent the oil from flowing back from the actuator (such as oil cylinder) to the oil tank, and ensure that the system can quickly build up pressure at the next start.
lubrication system
Ensure that the lubricating oil flows according to the set path and does not flow back to the oil reservoir due to pressure change.
Relationship with check valve
Return check valve "and" check valve "can be used interchangeably in many cases, and they refer to the function of the same type of valve, i.e. preventing the reverse flow of medium.
Check valve "emphasizes only one-way flow, while" check valve "more directly expresses the meaning of" stop "reverse flow, and both describe the function of the same type of valve
