Pressure anti-explosion decompression balance valve utilizing small-sized battery pack

Abstract

The invention discloses a pressure anti-explosion decompression balance valve utilizing a small-sized battery pack. The pressure anti-explosion decompression valve comprises an anti-explosion valve main body, wherein the anti-explosion valve main body is of a hub-type frame structure, a straight-through hole stacked blocking transverse plate structure is arranged inside the hub-type frame structure, the side surface of the blocking transverse plate structure is provided with a protection steel sheet, the interior of the protection steel sheet is of a circular-hole or an arc ventilation straight-through hole structure, a waterproof ventilation membrane is arranged between the anti-explosion valve main body and the protection steel sheet in a fitting manner, the inner wall of the hub-type frame of the anti-explosion valve main body is provided with a sealing strip in a buckling manner, and the outer wall of the hub-type frame of the anti-explosion valve main body is provided with an anti-explosion cover in a buckling manner. The pressure anti-explosion decompression balance valve utilizing the small-sized battery pack has the characteristics of high safety performance, convenience in use, low cost, good air tightness, excellent protection performance, good water resistance and convenience in detection.

Description

technical field [0001] The invention relates to the technical field of explosion-proof valves for batteries, in particular to a pressure-explosion-proof pressure relief balance valve using a small battery pack. Background technique [0002] At present, in the field of new energy auto parts PACK battery pack industry, the pressure explosion-proof pressure relief balance valve used is mainly installed in [0003] The side and front positions of the battery pack PACK products are installed with threaded and nuts, and the product structure is [0004] The shape, size, size, rough ore and heavy weight may affect the appearance effect after installation. The visual effect and the large external space will have a large external interference effect. When installed on the front of the PACK product, it is used outdoors for a long time. Now If the traditional explosion-proof valve is installed on the front, due to the long-term accumulation of a certain amount of ash layer and concret...

Problems solved by technology

[0004] The shape, size, size, rough ore and heavy weight may affect the appearance effect after installation. The visual effect and the large external space will have a large external interference effect. When installed on the front of the PACK product, it is used outdoors for a long time. Now If the traditional explosion-proof valve is installed on the front, due to the long-term accumulation of a certain amount of ash layer and concrete covering the pressure explosion-proof pressure relief balance valve products in the current market, there is a risk of the air flow rate decreasing. affect the service life of its products
