Description

Technical Field

[0001] The utility model relates to the technical field of dust removal valves, in particular to a dust removal valve which is easy to disassemble and repair for a second time. Background Art

[0002] From a functional perspective, dust removal valves are primarily used to control the on / off flow of dust-laden air, regulate flow, and change flow direction. By opening and closing valves, airflow in different parts of the dust removal system can be precisely controlled, ensuring efficient dust removal. For example, when equipment maintenance or filter bag replacement is required, the corresponding dust removal valve can be closed to isolate that part of the system for safe operation.

[0003] Most existing dust removal valves are fixed to the pipes by bolts or welding. However, the bolted connection is prone to rust due to long-term fixed connection, making it difficult to disassemble quickly. The welded pipes need to be disassembled by a cutting machine, which can easily cause damage to the pipes. The existing connection methods are inconvenient when the valves need to be disassembled and repaired due to problems, and cannot be disassembled and repaired quickly. Utility Model Content

[0026] In this embodiment, the outer fixed sleeve of the planar threaded disk 12 is provided with an external gear 15, and a mounting gear 16 is rotatably installed on the inner wall of one side of the mounting chamber.
