Abstract

The invention discloses an explosion-proof valve. The explosion-proof valve comprises a sliding block, wherein vent holes are formed in the sliding block; a body structure, wherein the sliding block and the body structure are in sliding fit, the body structure is provided with a vent channel communicating with the vent holes, and the body structure is suitable for being mounted on equipment to besubjected to pressure relief; and an elastic piece structure, wherein the elastic piece structure is provided with a vent port and elastic pieces capable of being elastically opened, the vent port communicates with the vent channel, and a vent film is arranged on the vent port. The explosion-proof valve is configured in the manner that when the pressure of an inner cavity of the equipment to be subjected to pressure relief is larger than preset pressure, the sliding block ejects the elastic pieces to form vent gaps, and the vent gaps communicate with the inner cavity of the equipment to be subjected to pressure relief. According to the explosion-proof valve, the ventilation and waterproof effects can be achieved, when thermal runaway happens, the sliding block ejects the elastic pieces toform the vent gaps, the safety and explosion prevention can be achieved, the elastic pieces can restore to original positions after pressure relief, and the explosion-proof function is repeatedly used.

Description

technical field [0001] The invention relates to the technical field of pressure control equipment manufacturing, in particular to an explosion-proof valve. Background technique [0002] With the country's vigorous promotion of new energy, electric vehicles have become the mainstream trend in the future. The key to the design of electric vehicles is the three-electric technology, including power batteries, motors, and electronic controls. Among them, the power battery is the core power supply component of the vehicle. , which determines the key indicators such as the mileage, cost, service life, and safety of the vehicle. During the use of the power battery, gas will be generated due to repeated charging and discharging of the battery cell. In order to ensure the air pressure balance inside and outside the power battery and at the same time ensure the airtight performance of the power battery, the battery must be equipped with a waterproof and breathable valve. This waterproo...
