Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve locking, in particular to a butterfly valve locking device. Background Art

[0002] A butterfly valve, abbreviated as a butterfly valve, refers to a valve with a closing part as a disc, which rotates around the valve axis to achieve opening and closing. It is mainly used for cutting off and throttling in pipelines. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or regulation. After the butterfly valve is processed, its surface defects must be processed, so the butterfly valve needs to be locked and fixed. The locking here is to limit the position of the butterfly valve, so the butterfly valve locking device is the limit fixing mechanism of the butterfly valve.

[0003] After searching, the applicant found that a Chinese patent disclosed "a butterfly valve locking device", and its publication (announcement) number is "CN212156020U". The patent mainly adopts a first limit plate and a second limit plate that are compatible with the butterfly valve body on both sides of the butterfly valve handle. The first limit plate and the second limit plate are each provided with at least one slot hole, wherein the slot holes on the first limit plate are all threaded holes, at least one slot hole on the second limit plate is a non-threaded hole, and the remaining slot holes are threaded holes; it also includes a lead screw and a nut sleeved on the lead screw, a locking ring is provided at one end of the lead screw, the lead screw is screwed with the slot hole of the first limit plate, and the threaded hole is threaded. The lever passes through the slot of the second limit plate or is screwed with it; thereby achieving the advantages of the butterfly valve locking device having a simple structure, easy installation and disassembly, excellent locking effect, and easy use. However, the traditional butterfly valve locking device, that is, the limit fixing device, generally adopts the extrusion fixation between multiple fixing parts, and the fixation of multiple fixing parts requires manual fixation by the operator. This process will not only increase the tediousness of multiple fixations, but also reduce the locking efficiency of the butterfly valve, and even affect the overall processing efficiency of the butterfly valve. In order to solve the above problems, a butterfly valve locking device is needed. Utility Model Content
