Zusammenfassung:	The utility model relates to a temperature control valve, which is installed on a return water pipe of a radiator in a steam and water heating system. The temperature control valve comprises a valve body, a valve cover, a valve clack, a valve seat, and a bimetal volute spring assembly. The utility model is characterized in that the valve clack is designed into a cylindrical shape; a small ball is arranged between a small pit on the center of the bottom of the valve clack and a base of the valve body; the small ball can play the action of supporting the valve clack as well as can reduce frictional force between the valve clack and the valve body; in addition, the driving method between the volute spring assembly and the valve clack adopts key drive; so the fabrication can be convenient, and the ceiling temperature and the floor temperature can be controlled. The utility model has the advantages of simple structure, small size, low cost, high sensitivity, and convenient processing and use.
