Self-reliance type temperature control valve using expansion of wax

摘要

The present disclosure relates to a magnetically controlled temperature control valve using the expansion force of the wax to enable stable operation according to the set temperature by using the stable expansion characteristics of the wax and the incompressible characteristics of water, in particular to enable low temperature control.;The present invention forms an inlet port through which the heat is introduced from the heating body on one side of the valve body having the upper and lower two-stage ports, and an outlet port through which the heat is discharged on the other side. Insert the valve member to be fitted in each port, and connect the outlet to the heating element to selectively heat the heating element, and configure two consecutive driving cylinders adjacent to the heating element to position the piston therebetween. The primary cylinder is filled with wax and the secondary cylinder is filled with water to expand the wax so that the piston pushes the water and pushes the water out. The secondary cylinder is connected to the driven cylinder and tube located on the upper part of the valve body. The valve member is connected to the piston of the driven cylinder so that the valve member can open and close each port selectively by the pressure of water, and the piece of the driven cylinder The lower part is interposed a compression spring to provide a restoring force.
