For water pressure relief purposes, water cooling system is a closed operation, with the rise of cold fluid temperature, will produce internal pressure, internal pressure will increase the connecting parts of the compressive strength, and indirectly affect the service life of the system and stability, through the release of internal pressure, can improve the stability of water cooling system, get the best state of low voltage operation.
As a water cooling system internal pressure discharge device, installed in the upper nozzle position, when pressed the front button, in the non sealed exhaust state, such as at the water outlet will lead to overflow of water, it is recommended installed in the upper part of the tank. Operating instructions: press the front button exhaust, release the key, automatically reset the seal.
