Explosion proof valve industry solutionsExplosion proof valve as battery safety"The last line of defense&", its 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.Hairis 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 needs to ensure the two functions of "breathing" and "protection" at the same time. The key lies in the following two core performances:
1. Air permeability test
Under the set pressure difference, the Hairis 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. Start the stress test
The Hairis HC flow-type air tightness detector is used to 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.
High-precision flow sensor with resolution up to 0.1 mL/min
It is not sensitive to changes in workpiece shape and internal volume, and has higher judgment consistency.
Supports automated integration and data storage analysis, suitable for large-volume online testing
Freely configure test parameters to adapt to different membrane materials and design requirements
