ABSTRACT:
A valve includes a chamber and two inlets for supplying cold and hot water into the chamber. A membrane is secured in the chamber so as to separate the inlets from each other. Two plugs are engaged in the inlets and secured to the membrane for blocking the inlets. Two springs are engaged on the plugs for balancing the membrane and the plugs. One of the plugs is forced to block one of the inlet when no water is supplied from the other inlet, so as to prevent the users from being hurt by hot water.
