When the electric six-way valve with heat insulation function is used to switch the flow direction of high-temperature fluid, the control module body 12 receives a signal, the DC motor 14 in the package device 1 rotates, thereby driving the output transmission shaft 2 of the motor speed reducer 13 to rotate, and the rotary torque is transmitted to the six-way valve rotating shaft 7 of the six-way valve body 5 through the connected universal joint mechanism 4, so as to realize the change of the flow direction of the high-temperature fluid in the six-way valve pipeline 6.

The transmission shaft 2 is fixed to the outer side of the output shaft of the motor speed reducer 13. The input yoke 11 is welded to the top end of the transmission shaft 2. Since the high-temperature fluid flows in the six-way valve pipeline 6, the valve core in the six-way valve body 5 is in a high-temperature state. The high-temperature heat is conducted to the output yoke 9 in the universal joint mechanism 4 connected with the six-way valve rotating shaft 7 of the six-way valve body 5.
