Summary:A gas control valve comprises a valve body provided with a gas channel and a valve core movably arranged in the gas channel, wherein the gas channel is provided with a conical channel surface; and the valve core is provided with a conical valve core surface matched with the conical channel surface to control gas flow. The gas channel and the conical channel surface of the gas control valve are matched with the conical valve core surface of the valve core so that the flow of gas passing through the gas channel is in a linear relation with the movement distance of the valve core. And thus, an ECU (electric control unit) is employed to control the flow of gas passing through the gas control valve according to the linear relation between the flow of gas and the movement distance of the valve core; therefore, the control of the ECU is convenient and simple.
