Other Industry SolutionsAs the "last line of defense" for battery safety, the explosion-proof valve's performance is directly related to the safety and reliability of the battery system.Explosion-proof valves need to maintain perfect sealing under normal operating conditions, open promptly when overpressure occurs, and effectively reset after pressure relief.Hirays provides professional testing solutions for the special functional requirements of explosion-proof valves to ensure that the explosion-proof valves play their due protective role throughout the battery life cycle.
The detection of explosion-proof valves must simultaneously ensure the two functions of "breathing" and "protection". The key lies in the following two core performances:
1. Air permeability test
Under the set pressure difference, the Hirays HC flow-type air tightness detector can be used to measure the gas throughput to determine whether it is within the design range.Ensure that the explosion-proof valve can discharge gas smoothly under working conditions such as temperature rise and altitude changes, and prevent shell bulging or sealing failure.
2. Opening pressure test
Using Hirays HC flow-type air tightness detector, gradually pressurize, accurately record the opening and reset pressure, and monitor leakage at the same time to ensure that the performance meets the design requirements.It ensures that when the internal pressure rises abnormally, the valve can quickly open to relieve pressure according to the preset pressure, and reliably close after the pressure drops to prevent the intrusion of external pollutants.
