Problems solved by technology

Although such a method can simply and effectively improve the explosion-proof performance of the battery, it is a self-destruction explosion-proof method, that is, an explosion-proof cover can only be used once, resulting in waste of materials and inconvenience in use, and poor practicability

Abstract

An adjustable explosion relief valve of a storage battery comprises a valve body, an adjusting nut, a pressure spring, a piston, a seal ring, a plug pin and a plug pin spring, wherein the adjusting nut is arranged at the back end of the valve body and connected with one end of the pressure spring arranged inside the valve body, the other end of the pressure spring is connected with one end of the piston, the other end of the piston is connected with the seal ring, the plug pin spring is arranged in the valve body and fixedly connected with the plug pin, a pit corresponding to the plug pin is arranged on the upper portion of the piston, a first channel is arranged on the inner side of the front end of the valve body and communicated with a cavity where the plug pin is arranged through a second channel, a through hole is arranged on the seal ring, and a decompression hole corresponding to the through hole is arranged on the valve body. The adjustable explosion relief valve has the advantages of being convenient to use, high in practicability, and capable of effectively controlling the inside pressure of the storage battery and preventing the storage battery from exploding due to the overhigh pressure inside.

Description

technical field [0001] The invention relates to an adjustable battery explosion-proof safety valve. Background technique [0002] Batteries are widely used in daily and industrial fields because of their low cost, stable performance, and convenient use. During the use of the battery, gas is generated inside the battery, causing the internal pressure of the battery to rise continuously, and the battery is very likely to explode. Battery explosions in many hazardous environments can have extremely serious consequences. Therefore, the explosion-proof performance of the battery is a very important performance index. [0003] At present, the most common anti-explosion measure for batteries is to install an explosion-proof cover plate for the battery, and process a weak part on the cover plate through various processes. When the pressure inside the battery rises and exceeds the pressure that the weak part can withstand, the weak part will Partially breaks, so that the pressure ...
