Abstract

The invention discloses a thermostatic valve for a water heater. The thermostatic valve comprises a valve body, a cold water inlet, a hot water inlet and a water outlet are formed in the valve body, the cold water inlet, the hot water inlet and the water outlet are communicated with a cold water thermistor, a hot water thermistor and a water outlet thermistor respectively, the cold water thermistor, the hot water thermistor and the water outlet thermistor are arranged at one end of the valve body, a turbine rotor with a magnet is arranged in the hot water inlet, the outer wall of the hot water inlet is provided with an insertion groove used for being connected with a Hall element in an inserted mode, and a ceramic valve element, an adjusting gear and a stepping motor are sequentially connected from an inner cavity of the valve body to the other end of the valve body. By means of the structure, rotation frequency of the stepping motor can be automatically controlled, and hot water inlet amount can be automatically adjusted through the ceramic valve element so that automatic thermostatic control of outflow water temperature can be achieved, and the thermostatic valve is convenient and safe to use.

Description

technical field [0001] The invention relates to a thermostatic valve, in particular to a thermostatic valve for a water heater. Background technique [0002] The outlet water temperature adjustment of existing water heaters is generally adjusted manually. The outlet water temperature cannot be accurately grasped, and it is troublesome to adjust. At the same time, because the water pressure is often unstable, the outlet water temperature cannot be kept constant. Hazard of personal burns. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a thermostatic valve for water heaters, which can realize automatic constant temperature adjustment of the outlet water temperature, and is convenient and safe to use. [0004] In order to solve the above technical problems, the technical solution of the present invention is to provide a thermostatic valve for water heaters, including a valve body, the valve body is provided with a ...
