Abstract
A thermostatic control valve comprises the following components: a valve body which comprises a cold water inlet, a hot water inlet and a mixed water outlet; a temperature-sensitive element in the valve body; and a piston which is driven by the temperature-sensitive element, and can regulate the water inflows of the cold water inlet and the hot water inlet; wherein: the valve body is arranged withat least two groups of cold water inlets and hot water inlets. The valve body is internally provided with at least two pistons for controlling the cold water inlets and hot water inlets, wherein onepiston is fixed with the temperature-sensitive element. Driving springs for ensuring the distance of adjacent piston are provided between the pistons. The piston is driven to move vertically through the expanding or shrinking of the temperature-sensitive element under the temperature variation of the outlet water to increase or reduce the cold water inlets and hot water inlets, regulate the amountof the cold water flow or hot water flow thereby stabilizing the temperature of outlet water. The cold water inlets and hot water inlets are increased on the valve body thereby realizing the functionof large flow. A plurality of pistons are connected by the driving springs which can realize synchronous motion while the regulated temperature is ensured. The driving springs have the dimension error compensation function thereby increasing the safety of the water discharged from the thermostatic control valve.
