Storage battery safety valve with high sealing performance

Abstract

The invention discloses a storage battery safety valve with high sealing performance. The storage battery safety valve comprises a valve body, wherein a pressing plate is fixedly welded on the outer wall of the bottom of the valve body; a sealing rubber ring is arranged above the pressing plate; the sealing rubber ring sleeves the outer wall of the valve body; a locking screw sleeve sleeves the upper part of the valve body; a storage battery upper housing plate is clamped between the sealing rubber ring and the locking screw sleeve; a limiting ring sleeves the outer wall of the upper part of the valve body; a bearing block is fixedly welded on the inner wall of the bottom of the valve body; a pressure relief through hole is formed in the middle of the bearing block; and a ball is embeddedabove the bearing block. According to the storage battery safety valve, a mushroom-shaped nut is arranged and can move up and down in the middle of a neutralization bin under the meshing action of threads, and the extrusion effect of the mushroom-shaped nut on a spring is adjusted by rotating the mushroom-shaped nut, so that the force required for jacking the ball upwards can be adjusted, the acidgas supporting force required for jacking the ball is flexibly adjusted according to the actual use condition, and the storage battery safety valve is flexible and convenient.

Description

technical field [0001] The invention relates to the technical field of battery accessories, in particular to a battery safety valve with strong sealing performance. Background technique [0002] A battery is a type of battery, also known as a storage battery, which can convert chemical energy into electrical energy. At present, the battery referred to by people refers to a lead-acid battery, which is filled with sulfuric acid solution as an electrolyte. When the battery is working, the internal electrolyte It will react and easily produce acid gas. If the pressure is not released in time, it will easily cause the side wall of the battery to bulge under the action of gas pressure, which will reduce the service life of the battery. For this reason, a safety valve is usually installed above the battery. Relieve the pressure in time, but the current battery safety valve is mostly directly snapped on the top of the battery, which is easy to fall off, and the seal is not tight whe...
