Abstract

The utility model discloses a novel battery safety valve, including the valve body, case group. The upper part of the surface of the valve body is provided with two rubber rings, the periphery of the lower end surface is provided with the rubber rings, and the inner hole is provided with two concave rings; the case group is combined with the valve body through the twice bulge loop of case seat, the utility model discloses the effect of the spacing card of case that is equipped with through the case seat during use is used and is spacing with the cooperation of case seat to rubber case, makes its opening and closing valve pressure uniformity good, and the valve body is through the case group that is equipped with the bulge loop rather than the lower extreme when sealing the cooperation, it does not have the spacing to rubber case, can carry out pressure test to case group earlier, only scrap the case group that can not reach technical requirement, and need not wholly scrap, can practice thrift the cost, interference fit through the recess that the twice bulge loop that is equipped with on the case seat and valve body were equipped with, and the rubber ring cooperation of terminal surface under the valve body, play and prevent pressure release, its sealed leak protection effect is better.

Description

Novel safety valve of storage battery

Technical Field

The utility model belongs to the technical field of the battery relief valve, concretely relates to novel battery relief valve.

Background

At present current relief valve utilizes valve body and valve core case to carry on spacingly to rubber valve core, and the valve core case is the plane interference fit of the rubber of moulding plastics with the valve body secondary for the cooperation of valve core case bottom plane with the valve body, in order to guarantee not to let out pressure, the bulge loop of valve core case side only plays the positioning action, plane interference fit plays the leak protection effect, but the valve body, the valve core case is the PP material entirely, the shaping shrinkage factor is big, it is big to receive the temperature influence deflection, it is too big to have caused the closed valve pressure deviation under the environment of difference after the installation, if the whole scrapping of needs that open and close valve pressure can not reach technical requirement simultaneously, the.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel battery safety valve to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel battery safety valve, includes the valve body, the case subassembly, valve body surface upper portion is equipped with twice rubber seal ring, valve body lower extreme surface a week is equipped with rubber seal ring, and hole department is equipped with two to spacing sealed recess, constitute the case group with the valve body combination through the twice bulge loop that sets up on the case seat, the valve body is through making up the use rather than the case group that the lower extreme was equipped with the bulge loop.

Preferably, the valve core limiting clamp arranged on the valve core seat is used for matching and limiting the rubber valve core and the valve core seat.

Preferably, two grooves are formed in the inner side of the valve body.

Preferably, the valve body is matched with the valve core group.

Compared with the prior art, the utility model discloses a technological effect and advantage: this novel battery safety valve, the cooperation and the spacing of rubber case and valve core case are carried out through the effect of the spacing card of case that sets up on the valve core case during the use, because the spacing card of case adopts polymer PC to make with the valve core case, its variation is little, it is little influenced by the temperature, the cooperation precision is high, open and close valve pressure uniformity is good, and the valve body does not exist the spacing to rubber case when sealing the cooperation through the recess that is equipped with rather than the lower extreme with the valve core group, consequently, can carry out pressure test to the valve core group earlier, just assemble after qualified, only scrap the valve core group that can not reach technical requirement, and do not need whole to scrap, can practice thrift the cost, interference fit through the recess that two rings that add on the valve core case and valve body were equipped with, further play and prevent pressure release, its sealed leak protection effect is better.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a novel battery safety valve, includes valve body 1, its characterized in that: the upper part of the surface of the valve body 1 is provided with two rubber sealing rings, one circle of the lower end surface of the valve body 1 is provided with the rubber sealing ring, the inner hole is provided with two limiting sealing grooves, the two convex rings arranged on the valve core seat 4 are combined with the valve body 1 to form a valve core group, the valve body 1 is combined with the valve core group with the lower end provided with the convex ring, and the rubber valve core 3 is matched with the valve core seat 4 for use and limiting under the action of a valve core limiting clamp 2 arranged on the valve core seat 4 when the valve body is used; the valve body 1 is combined with the valve core group provided with the convex ring through the groove arranged at the lower end of the valve body.

Specifically, two convex rings are arranged on the outer surface of the valve core seat 4 to prevent the relief valve from releasing pressure.

Specifically, two grooves are formed in the inner side of the valve body 1, and the leakage-proof function of the safety valve is achieved.

Specifically, the valve core limiting card 2 in the valve core group is matched with the valve core seat 4 to play a role in controlling the opening and closing pressure of the safety valve.

When the valve core group is used specifically, the valve core 3 and the valve core seat 4 are matched for use and are limited under the action of the valve core limiting clamp 2 arranged on the valve core group, so that the opening and closing valve pressure consistency is good, and when the valve core group is in sealing fit with the valve body 1 through the convex ring arranged at the lower end of the valve core group, the limit to the rubber valve core 3 does not exist, the pressure test can be firstly carried out on the fit of the valve core group, only the valve core group which cannot meet the technical requirements is scrapped, the whole scrapping is not needed, the cost can be saved, the interference fit of two convex rings arranged on the valve core seat 4 and the groove arranged on the valve body 1 and the interference fit of the lower plane of the valve core seat 4 and the lower plane rubber of the valve body 1 are realized, the pressure relief is.
