Heated body of self-starting valve

A heated body of a self-starting valve comprises a fast heated body and a heat conduction sleeve, the fast heated body is composed of a plurality of heated pieces and a middle cylinder which are distributed in a radial mode, the heated pieces and the middle cylinder are integrally formed, the middle cylinder is fixedly connected to the periphery of the heat conduction sleeve in a sleeved mode, the height of the middle cylinder is lower than that of the heat conduction sleeve, and a connecting section is exposed on the heat conduction sleeve. The connecting section of the heat conduction sleeve is inserted into the connecting cylinder of the valve body, the connecting section of the heat conduction sleeve and the connecting cylinder are bonded together through hot melt adhesive, the valve body is connected with an outlet of the total flooding type automatic fire extinguishing device through threads of the connecting body, the top of the heat conduction sleeve extends to form a conical connector, and a first th
