Abstract
The utility model discloses an integrated micro-battery safety valve comprising a valve deck and a valve body where external threads are installed. An annular protrusive extending part is arranged in an inner cavity of the valve body, a diaphragm and a pressure spring are sequentially arranged in the annular protrusive extending part, and a groove is formed in the bottom of the valve body by one circle. An annular seal ring is inlaid in the groove. The size of the safety valve is reduced, overall space of a battery is reduced, the volume density of the battery is reduced, and the integrated micro-battery safety valve is light in structure and meanwhile resistant to acid, alkali and ageing and does not deform at high temperature.
Description
Technical field
The utility model relates generally to field of batteries, relates in particular to a kind of integrated micro battery safety valve.
Background technique
The general volume of safety valve that lithium cell uses is now excessive, and structure is very complicated.
Model utility content
The utility model object is exactly the defect in order to make up prior art, and a kind of integrated micro battery safety valve is provided.
The utility model is achieved through the following technical solutions:
A kind of integrated micro battery safety valve, include valve gap and be provided with externally threaded valve body is installed, described body cavity is provided with annular convex extension part, in described annular convex extension part, be provided with successively diaphragm and pressure spring, described valve body bottom one circle is provided with groove, in described groove, is inlaid with O-ring seal.
Described valve body of safety valve adopts high-strength corrosion-resisting material.
Described diaphragm adopts has good flexible acid-alkali-corrosive-resisting material.
The supporting pressure spring that has different size of described safety valve.
The utility model has the advantages that:
The utility model has reduced the volume of safety valve, has reduced cell integrated space, has reduced the volume density of battery, and structure is light, simultaneously can acid resistant alkali, and high temperature is indeformable, should have certain ageing resistance simultaneously.
