Product introduction

Battery safety valve, also known as battery exhaust valve, is a valve that plays a role in the safety protection of valve-controlled batteries.Inside the battery work reflect the released gas lead to the battery internal pressure increase gradually, when the threshold pressure to open the valve, safety valve, automatically open the exhaust gas in the battery internal pressure drop to threshold after closing valve, safety valve automatically shut down, at the same time in the process can prevent external gas into the battery and battery acid spills.It can avoid bulging and explosion caused by excessive pressure in the battery or oxidation failure of the battery reaction liquid caused by external gas entering the battery.
