The water cooling system is mostly in a closed operation state. As the temperature of the coolant increases, internal pressure will be generated. The internal pressure increases, and the pressure at each connection part increases, which affects the stability of the system.
By pressing the front button, the gas can be discharged, the air pressure can be reduced, and the button can be released to automatically reset the seal
The exhaust valve is installed on the top of the water tank, and the liquid should not be higher than the plug (if the bottom is installed, the exhaust effect cannot be achieved, and it may leak)
