Cold and hot water mixing battery - incorporates membrane valves controlled by pressure sensor valve within water inlets

摘要

The mixing battery for cold and warm water has membrane valves controllable by pressure sensor. The valve seats in the cold and warm water inflow work in conjunction with the membranes of the valves, the membrane being loaded in the open direction by inflow pressure from the ring channels surrounding the valve seat, and in the closed direction on their whole surface from control chambers connected with the inflow chambers by narrow pressure balancing apertures. They are unloaded after outflow by pressure sensor operation. Both valve membranes are tensioned against the battery housing by a valve upper part containing the control chambers, and a pressure sensor valve is centrally located.
