Abstract

The invention discloses a new energy battery explosion-proof valve, which comprises a main valve body, a seal ring, a piece of explosion-proof membrane paper, a membrane paper protection plate and a protective cover, wherein a membrane paper mounting platform is arranged at one side of the main valve body; the explosion-proof membrane paper is welded on the membrane paper mounting platform in a hot melting manner; an annular bump is arranged on the outer circumference of the membrane paper mounting platform; the membrane paper protection plate is arranged in the annular bump; a protective bottom plate is arranged at the lower part of the membrane paper mounting platform; the protective bottom plate is provided with an explosion-proof pointed cone toward the explosion-proof membrane paper; the protective cover is arranged out of the protective bottom plate; the seal ring is arranged between the outer surface of the annular bump and the main valve body; the main valve body is movably connected with a battery shell through the annular bump; and the main valve body and a battery shell are sealed through the seal ring. The new energy battery explosion-proof valve has the advantages of being simple in structure, low in cost, dustproof, waterproof, explosion-proof and breathable, and can balance internal pressure and external pressure of a sealed accommodating cavity of a battery.

Description

technical field [0001] The invention relates to the field of battery explosion-proof technology, in particular to a new energy battery explosion-proof valve. Background technique [0002] The existing battery explosion-proof valve is mainly composed of an adjustable vent valve, an explosion-proof ball and a spring, and a vent base. The adjustable vent valve is installed on the vent base, and a spring and an explosion-proof ball are arranged between the two. on the exhaust duct. Because the gas generated in the battery becomes alkaline, such gas has a corrosive effect on the metal spring, and the spring is easily damaged after a long time, and cannot provide the set force, so it is easy to appear when the internal pressure has not reached a dangerous value. Explosion-proof The valve is opened, and when the spring is completely damaged, the explosion-proof valve will fail, which will easily cause accidents. At the same time, the setting of the deflation base makes the inside...
