Description

Technical Field

[0001] The utility model relates to the technical field of spherical single-flow valves, in particular to a spherical single-flow valve. Background Art

[0002] A ball check valve is a simple one-way flow control device, also known as a ball valve or a reverse check valve. This type of check valve usually has a spherical valve core that is designed to seal with the valve seat on the valve. When the fluid flows in the correct direction, the valve core is pushed by the hydraulic pressure to open the valve. But when the fluid flows backward, the spherical valve core is compressed by the spring on the valve seat to prevent reverse flow.

[0003] However, the principle of some existing single-flow valves is to push the sealing seat according to the direction of the fluid, making up and down movements to open and close the valve, and at the same time to achieve the sealing of the valve through the tension of the spring. This process is relatively complicated and difficult to process. Utility Model Content
