Description

Technical Field

[0001] The utility model mainly relates to the field of manual valves, and in particular to a labor-saving valve. Background Art

[0002] Manual valves are control components in pipeline fluid delivery systems. They are used to change the cross-section of the passageway and the direction of the medium's flow, performing functions such as diversion, shutoff, regulation, throttling, check valves, diversion, or overflow pressure relief. Valves used for fluid control range in nominal diameter from extremely small instrument valves to valves for industrial pipelines with diameters up to 10 meters. Valves can operate according to predetermined requirements in response to pressure, temperature, or other sensor signals, or simply open or close independently of sensor signals. Valves rely on a drive or automatic mechanism to cause the opening and closing elements to move upward, downward, slide, swing, or rotate, thereby changing the size of the flow path to achieve their control function.

[0003] During the operation of the specific embodiment, the inventors found the following defects:

[0004] However, manual valves need to be opened and closed manually, but the closing and opening of the valve core are mainly controlled by a screw. Each time the manual valve is opened and closed, the screw in the manual valve needs to be rotated more than ten or dozens of times. This method makes it impossible for the manual valve to be closed and opened quickly.

[0005] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content
