Plastic-component explosion-proof pressure-relief balancing valve quick to mount

Abstract

The invention discloses a plastic-component explosion-proof pressure-relief balancing valve quick to mount. The plastic-component explosion-proof pressure-relief balancing valve quick to mount comprises an explosion-proof valve main body, wherein a through ventilating hole is arranged inside the explosion-proof valve main body; one end of the explosion-proof valve main body is connected with a protecting cover in a fastening manner; a ventilating through groove is arranged inside the protecting cover; the other end of the explosion-proof valve main body is movably connected with a plastic nut by a sealing ring and by adopting a thread; a place where the explosion-proof valve main body is in threaded connection with the plastic nut is provided with a waterproof ventilating film and a protective steel sheet in the fastening manner; the waterproof ventilating film is fastened to a mouth part of the through ventilating hole by the protective steel sheet; the explosion-proof valve main body is provided, on the inner wall of the mouth part of the through ventilating hole, with a protecting film piercing convex column; and the protecting film piercing convex column and the waterproof protecting film are arranged in a parallel abutting manner. The plastic-component explosion-proof pressure-relief balancing valve quick to mount, which is provided by the invention, has the characteristics of being excellent in protective performance, convenient to use, low in cost, good in gas tightness and good in waterproofing quality.

Description

technical field [0001] The invention relates to the technical field of battery explosion-proof valves, in particular to a quick-install explosion-proof pressure relief balance valve for plastic parts. Background technique [0002] At present, in the field of new energy auto parts PACK battery pack industry, the main installation method is to use screws inside the PACK battery pack to lock and fix the explosion-proof pressure relief balance valve on the sealed shell, so that the manual installation efficiency is greatly improved. It is necessary to open four through holes on the installation shell, and the post-processing process is complicated; secondly, because the installation size of the side part of the shell designed by the manufacturer of the PACK battery pack is narrow, the traditional explosion-proof, pressure-relief and explosion-proof valve products are due to long The larger the width, it is easy to cause interference problems, which makes the selection of install...

[0002] At present, in the field of new energy auto parts PACK battery pack industry, the main installation method is to use screws inside the PACK battery pack to lock and fix the explosion-proof pressure relief balance valve on the sealed shell, so that the manual installation efficiency is greatly improved. It is necessary to open four through holes on the installation shell, and the post-processing process is complicated; secondly, because the installation size of the side part of the shell designed by the manufacturer of the PACK battery pack is narrow, the traditional explosion-proof, pressure-relief and explosion-proof valve products are due to long The wide size is large, which is easy to cause interference problems, resulting in difficulties in the selection of installation and high production costs of traditional products.
