Problems solved by technology
[0003] In the prior art, during the use of the explosion-proof valve in the new energy battery, the deflection and dislocation of the pressure bead under the action of the spring after multiple deflations caused the poor stability after rebounding, which is not conducive to Long-term use, so that after a period of time, there will be problems such as poor air leakage and sealing effect, which will affect the normal use of the battery explosion-proof valve and is not conducive to prolonging the service life of the explosion-proof valve

The invention discloses a new energy battery explosion-proof valve with a pressure bead, and particularly relates to the technical field of battery explosion-proof valves. The new energy battery explosion-proof valve comprises a protection valve shell, the bottom end of the protection valve shell is connected with a connecting sleeve frame shell, a valve unloading sealing sleeve is arranged in the connecting sleeve frame shell, and the top end of the valve unloading sealing sleeve is connected with a connecting sleeve; and a stabilizing mechanism is arranged in the connecting sleeve. A stabilizing mechanism and a buffer linkage rod are adopted to drive an extrusion sleeving shaft ring to move upwards along an adjusting screw rod, the extrusion sleeving shaft ring begins to extrude and connect an extrusion ring, in this way, it can be guaranteed that a sealing pressure ball stably moves upwards, and therefore the stable guiding operation on the sealing pressure ball in the pressure relief process is effectively improved; therefore, the sealing pressure ball is prevented from deviating in the pressure relief process, the service life of the sealing pressure ball is effectively prolonged, faults are avoided, and the anti-explosion valve is more convenient to use.
Description
technical field [0001] The invention relates to the technical field of battery explosion-proof valves, and more specifically, the invention relates to a new energy battery explosion-proof valve with pressure beads. Background technique [0002] The new energy battery is the power source that provides the power source for the tool. Most of them refer to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. Type lead-acid batteries, open-type tubular lead-acid batteries and lithium iron phosphate batteries. During the use of new energy batteries, new energy batteries are sealed and will generate high temperatures during operation. This requires an explosion-proof venting valve to Dissipate hot gas, thereby preventing problems such as severe inflation and explosion in the sealing position. [0003] In the prior art, during the use of the explosion-proof valve in the new energy battery, the deflection and dislocation of the p...
