Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure gate valves, in particular to a maintenance and disassembly mechanism for a movable sealing type high-pressure gate valve. Background Art

[0002] The opening and closing parts of the high-pressure gate valve are gate plates, and the movement direction of the gate plates is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The high-pressure gate valve is usually installed on the inner wall of the pipeline to restrict the liquid in the pipeline. Since the high-pressure gate valve is always subjected to the impact of water flow, it needs to be disassembled for maintenance or replacement after a period of use, which requires a maintenance and disassembly mechanism of the movable sealed high-pressure gate valve. Therefore, the maintenance and disassembly mechanism of the existing movable sealed high-pressure gate valve has been continuously innovated and developed. Therefore, it can be seen that the current maintenance and disassembly mechanism of the movable sealed high-pressure gate valve basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN217030327U discloses a gate valve that is easy to disassemble and assemble, including a gate valve; a pipeline is attached to both sides of the gate valve, and a quick disassembly mechanism is arranged at both ends of the gate valve; the quick disassembly mechanism comprises a plug plate, a telescopic rod, a spring, a sliding mechanism and a pressing mechanism, and the plug plate is inserted inside the gate valve; the end of the plug plate away from the gate valve is inserted inside the pipeline, and the outer side of the plug plate is fixedly connected to the telescopic rod; the side of the telescopic rod away from the plug plate is fixedly connected to the gate valve, and a spring is sleeved on the outer side of the telescopic rod; the end of the spring away from the plug plate is fixedly connected to the gate valve, and the end of the spring close to the plug plate is fixedly connected to the plug plate; the sliding mechanism is arranged on the side of the plug plate away from the pipeline, and the pressing mechanism is arranged on the side of the plug plate away from the telescopic rod; by arranging the quick disassembly mechanism, the gate valve and the pipeline are easier to disassemble and assemble, the disassembly steps are reduced, and the disassembly efficiency is improved. By arranging the telescopic rod and the spring, the gate valve and the pipeline are easier to disassemble and assemble, the disassembly steps are reduced, and the disassembly efficiency is improved.

[0004] However, when the above device is actually used, one end of the telescopic rod is inserted into the inner wall of the pipe for connection. When the pipe is subjected to a certain vibration, the spring and the telescopic rod will inevitably shake and contract. After the telescopic rod contracts, the fixation of the pipe is released, causing the pipe to loosen or even fall off. Therefore, a maintenance and disassembly mechanism for a movable sealed high-pressure gate valve is urgently needed to solve the above problem. Utility Model Content
