Wiring diagram of gas stove solenoid valve

Generally, the solenoid valve has two wires, red is the positive electrode connected to the power supply, and black is the negative electrode connected to the power supply. But it must be determined whether the solenoid valve is 12v or 24v. If it is a DC voltage solenoid valve, it must not be directly connected to the AC voltage of 220v V.

The solenoid valve is a part of the valve body, which is installed in the valve body (the valve body consists of microswitch, cone valve, solenoid valve and aluminum die-casting shell). The microswitch is connected to the power supply, the electromagnetic valve is connected to the thermocouple, and the thermocouple is equivalent to an inductor. When the flame touches a certain temperature, the electromagnetic valve opens, and an accidental flameout protection device is formed through the suction of the electromagnetic valve.

If the thermocouple does not sense the flame temperature, the electric valve will close. Valve body is the control system of gas stove, which is used to control the switch of gas path.

Extended data:

There is a closed cavity in the solenoid valve, and there are through holes in different positions. Each hole is connected with a different oil pipe. There is a piston in the middle of the cavity and two electromagnets on both sides. When the electromagnetic coil on which side is energized, the valve body will be attracted to which side. By controlling the movement of the valve body, different oil discharge holes will be opened or closed, while the oil inlet hole is always open. Hydraulic oil will enter different oil discharge pipes, and then the piston of the oil cylinder is pushed by the oil pressure, which in turn drives the piston rod, which drives the mechanical device. In this way, the mechanical movement is controlled by controlling the on-off of the electromagnet. ?

Principle: When the power is on, the electromagnetic force opens the pilot hole, and the pressure in the upper chamber drops rapidly, forming a pressure difference between the upper and lower parts around the closing part, and the fluid pressure pushes the closing part to move upward, thus opening the valve; When power is cut off, the pilot hole is closed under the action of spring force, the inlet pressure quickly forms a low-high pressure difference around the closing valve through the bypass hole, and the fluid pressure pushes the closing piece to move downwards to close the valve.
