Abstract
A vertical rotor type gas solenoid valve comprises a valve case (14), a regulating spring (11), a regulating nail (10), a rotor regulating screw (9), a regulating screw bracket (12), a swing arm (18), a sealing gasket component arranged at an outer end of the swing arm (18), and a vertical rotor type electromagnet. The valve case (14) comprises a gas net (15), a gas outlet (16) and a valve port (17). The gas flow and the curve of the gas flow against the electric current of the winding can be regulated, and the minimum starting point of gas flow is determined.
