Claims (1)

[Scope of utility model registration request] A thermostatic mixing valve comprising a uniaxially operated control valve for mixing water and hot water supplied into a main body, the valve body of the control valve being connected to a temperature sensing element sensitive to the temperature of the mixed water, the valve The valve body is slidably inserted into a mounting seat formed inside the main body, and water and hot water are controlled by the valve opening between a water valve seat and a hot water valve seat formed in the moving direction of the valve body. The thermostatic mixing valve is characterized in that the mixing ratio of the valve body can be set, and the valve body is made of a synthetic resin material having a coefficient of linear expansion larger than that of the main body.
