The work operation is noiseless, and the mounting means is connected to the nut, and is simple, the installation is rapid, and it is convenient to dismantle.

The electric heating actuator is divided into a normally-open type and a normally-closed type, wherein the normally-closed type means that a valve controlled by the actuator is in a closed state under the condition of no power supply. The working principle is that when the temperature needs to be raised, the sensor device is electrified to heat the sensor device, so that the paraffin core inside expands to push the support to rise, the valve rod of the valve rises, and the valve is opened to start heat supply. When the pressure is required to be pressed to test the pipeline tightness after the first installation, the valve cannot be opened, the electric heating actuator and the valve are required to be separated to open the valve, and the workload of disassembly and installation is invisibly increased.
