Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an anti-water seepage stainless steel valve. Background Art

[0002] Valves are common components in pipelines. Their main function is to control the flow of fluid in the pipe. The valve stem and the valve body are movably connected, so there is inevitably a gap at the connection between the valve stem and the valve body. In order to prevent the fluid from leaking from the gap, a sealed valve stem sleeve is often provided on the outside of the protruding part of the valve stem to wrap the entire valve stem and the valve body The connection position, and the valve stem sleeve and the valve body are welded.

[0003] A search of CN 212107155U discloses a water-seepage-proof stainless steel valve. In this solution, the valve stem is sleeved inside the valve body, which effectively avoids the problem of water seeping out of the valve body after the connection position between the valve stem and the valve body is corroded.

[0004] However, after the applicant studied the scheme and combined it with the prior art, the following problems were found. First, in this scheme, the valve stem sleeve is arranged inside the valve body. Since the valve disc needs to circulate for a long time, wear will occur at the intersection of the valve disc and the valve stem sleeve. Therefore, the sealing performance will decrease after long-term use. In addition, the valve stem sleeve is arranged inside the valve body, which is not convenient for disassembly and welding. Once water seepage occurs, it cannot be discovered in time, and it is extremely inconvenient to repair and replace accessories. Therefore, it does not conform to the actual use scenario. In this regard, we propose an anti-seepage stainless steel valve. Utility Model Content

[0017] Through the above technical solution: the spring caliper is rotated to form a clutch state with the base, so that the handle is fixed and operable, which is convenient for adjusting and fixing the fixed angle of the valve disc.

[0018] The beneficial effects of the utility model are:

[0019] 1.
