Structural principle of one-way valve（3）
Structural Principle:
A one-way valve generally consists of a valve body, valve core, spring, etc. The valve body is generally spherical, conical or cylindrical, and the valve core is installed inside the valve body, which can move to a certain extent. The top of the valve core is usually in contact with the valve body and is usually pressurized by a spring. When there is a pressure difference, the valve core separates from the valve body and allows oil to flow forward. When the pressure difference does not exist, the contact between the valve body and valve core will be maintained to prevent oil backflow.
Working Principle:
The medium inside it flows in one direction to prevent reverse flow. Usually, this valve operates automatically. Under the pressure of unidirectional fluid flow, when the valve disc opens and the fluid flows in the opposite direction, the valve disc overlaps with the valve seat through fluid pressure, thereby cutting off the flow. For example, when the air compressor inflates the air storage tank, a one-way valve should be installed between the air compressor and the air storage tank to prevent the air from flowing back into the compressor when the air compressor stops.
