　　What are the functions of gas stove valve body?

　　It is mainly used for gas circuit control and gas flow regulation. The utility model is composed of a gas valve body, a gas valve core, an ejector tube, a knob rod, a positioning device, a transmission device and accessories for realizing the function transformation requirements. The gas valve core is a device for regulating the gas flow and controlling the gas path. This is because there is a specific viewpoint between the air hole of the gas valve core and the air inlet of the gas valve body. When the knob rod is pressed and does not rotate, the air hole of the gas valve core is not aligned with the air inlet, The gas passage is still blocked; If the burning is successful at this moment, turn the knob, the gas circuit will be connected, and the gas will be ignited;

　　If the incineration fails and the knob does not roll, the gas overflow can be avoided; The air holes with different diameters on the gas valve core restrict the flow of gas and control the size of the flame of the gas stove. The positioning device is composed of a positioning block and a positioning groove in the valve body. In the "closed" state, the positioning block is sleeved in the positioning groove, and the knob cannot roll. When the knob is pressed and rotated, the positioning block rotates and breaks away from the positioning constraints, ensuring that the knob can roll freely within a specific range after loosening the hand to adjust the size of the firepower.
