Abstract
The invention discloses a safety valve for a battery. The safety valve comprises a valve body, wherein the top part of the valve body is provided with an adjusting plug; a step outside of the lower part of the valve body is provided with a sealing ring; the periphery of the valve body is provided with exhaust holes; the bottom part of the adjusting plug is connected with the top part of a conical spring in a valve cavity; the bottom part of the conical spring is sleeved on a metal valve piece in the valve cavity; and the bottom part of the metal valve piece is connected with an explosion-proof piece. The safety valve for the battery has long service life, and can ensure the safe storage and use of the battery effectively.
Description
Technical field
The present invention relates to a kind of battery safety component, particularly a kind of battery safety valve.
Background technology
At present, known battery safety valve is to be combined by safety valve body, adjusting plug, plastic spacer, explosion-proof ball, is contained on the battery cover.Explosion-proof ball is generally made by rubber, and when the inner pressure of battery rising reached the pressure release starting pressure, explosion-proof ball was compressed, and the safety valve exhaust reduces inner pressure of battery.But the flexible sensitivity inadequately of rubber explosion-proof ball when the gas that produces in the battery surpasses setting pressure, often can not in time be discharged from inside battery, thus the potential safety hazard of causing.
Summary of the invention
The present invention is intended to overcome the above-mentioned defective that existing battery safety valve exists, and provides the air pressure in a kind of battery to be quick on the draw the safety valve of reliable operation.
Purpose of the present invention is achieved by the following technical programs:
It comprises valve body, and adjusting plug is equipped with at the valve body top, and step place, the valve body lower portion outside is provided with sealing ring, have steam vent around the valve body, adjusting plug bottom joins with volute spring top in the valve pocket, and the volute spring bottom is enclosed within on the valve metal film in the valve pocket, and the valve metal film bottom is connected with burst disk.
Preferred version: safety valve body inside is provided with the boss of protuberance, and the burst disk bottom surface places on the described boss, to prevent battery leakage.
Volute spring in the valve pocket of the present invention matches with valve metal film, raises when reaching the pressure release starting pressure at inner pressure of battery, and the easier unlatching exhaust of valve metal film greatly reduces the set point of Pneumatic pressure, helps guaranteeing that battery is safe in utilization.Simultaneously, adjusting plug can be adjusted according to the explosion-proof starting pressure of difference, thereby, applicable to pressure release there being the different batteries that require.
The present invention's battery safety valve long service life can effectively guarantee Ni-MH power cell safe storage, use.And bossed boss in the safety valve body can effectively prevent battery leakage.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.These embodiment must not be used to explain limiting the scope of the invention.
With reference to Fig. 1, present embodiment comprises safety valve body 1, the valve pocket inner top of safety valve body 1 is equipped with adjusting plug 2, step place, the outside, safety valve body 1 bottom is provided with sealing ring 6, have steam vent around the safety valve body 1, volute spring 3 tops in adjusting plug 2 bottoms and the valve pocket join, and volute spring 3 bottoms are enclosed within on the valve metal film 4 in the valve pocket, and valve metal film 4 bottoms are connected with burst disk 5.
Safety valve body 1 valve pocket inside is provided with the boss 7 of protuberance, and burst disk 5 places on the described boss 7.
By the pressure of 2 pairs of volute springs 3 of adjusting plug, can adjust different explosion-proof starting pressures.When inside battery air pressure constantly increases, when reaching opening pressure, gas is compressed volute spring 3 to the pressure of burst disk 5, and steam vent is opened, and gas is discharged, and makes inside battery air pressure drop to rated value.
Claims (2)
1. battery safety valve, comprise valve body, adjusting plug is equipped with at the valve body top, step place, the valve body lower portion outside is provided with sealing ring, have steam vent around the valve body, it is characterized in that, the volute spring top in adjusting plug bottom and the valve pocket joins, be enclosed within bottom the volute spring on the valve metal film in the valve pocket, the valve metal film bottom is connected with burst disk.
