Description

Technical Field

[0001] The utility model relates to the technical field of stop valve structures, in particular to a stop valve which is convenient for finely adjusting the flow of a water body. Background Art

[0002] The stop valve relies on the valve stem pressure to make the valve disc sealing surface fit closely with the valve seat sealing surface to prevent the flow of medium. Its main function is to fully open or fully close, which means cutting off the medium. Therefore, the stop valve is usually used as a cut-off valve.

[0003] But as the stop valve gradually develops and improves, it now also realizes the functions of regulation and throttling. The medium passes through the gap between the valve disc and the valve seat. However, the flow regulation of this method is relatively poor, and the flow regulation is not stable enough. Under the impact of the medium, the sealing surface is severely worn, affecting the cut-off effect. Utility Model Content
