Description

Technical Field

[0001] The utility model relates to the technical field of gate valve cleaning, in particular to a disassembly and cleaning mechanism for a high-pressure resistant hard-sealed gate valve. Background Art

[0002] A gate valve is a valve whose closing part moves in the vertical direction along the center line of the passage. The gate valve can only be used for full opening and full closing in the pipeline, and cannot be used for regulation and throttling. The gate valve is a valve with a wide range of applications. After long-term use, the valve structure will have residual scale after the water flows through it. Long-term attachment will cause damage to the inner wall structure, so it is necessary to use related disassembly and cleaning structures for cleaning.

[0003] Its gate valve structure, as an independent valve structure, is disassembled as a whole. When cleaning it relies on immersion and manual hand-held cleaning, the labor burden caused by its own gravity is high. Its general flushing structure makes it difficult to clean the attached scale. Therefore, the present application proposes a set of new gate valve disassembly and cleaning mechanisms to meet more usage needs. Utility Model Content

[0024] When the device is used for cleaning the sealed gate valve, and after the arc-shaped supporting frame 6 is clamped and placed inside the cleaning chamber 1, the gate valve can be placed on the top of the arc-shaped supporting frame 6. After placement, the steering frame 9 can be adjusted to the top of the cleaning chamber 1, so that the bottom clamping seat 12 corresponds to the position where the gate valve is placed.
