Abstract

The invention discloses a vertical rotor fuel gas solenoid valve, the structure of which can lead a magnetic circuit of the solenoid valve to be shortened and lead the processing technique to be simple, and the concentricity of a rotor and a stator has accurate location and convenient adjustment, and the relation curve of the fuel gas flow rate and current can be adjusted at any time, so the smallest starting point of the fuel gas flow rate can be determined and the adjustment and location are accurate; the solenoid valve can be used for adjusting the fuel gas flow rate and used as a switch, and the solenoid valve can be changed into a strong absorbing valve. The fuel gas solenoid valve comprises a vertical rotor electromagnet, a rotor adjusting bolt, a bracket, a spring and an adjusting bolt; a sealing gasket and a gasket spring are arranged on round lug boss at the external end of a swinging arm which is fixedly connected with a rotor shaft, and the round lug boss is connected with a valve port in a matching way for adjusting the fuel gas flow rate; the transverse positions of the rotor adjusting bolt and the bracket are adjusted for adjusting the relation curve of the fuel gas flow rate and the winding current, and the smallest starting point of the fuel gas flow rate can be determined.

Description

technical field [0001] The invention relates to the technical field of gas solenoid valves, in particular to a vertical rotor type gas solenoid valve. Background technique [0002] The rotor type solenoid valve uses the rotor type electromagnet as the driving element. The rotor type electromagnet uses its rotating shaft to fix the iron core of the rotor. The gap between the rotor iron core and the stator iron core can be small, but the shaft and the bearing will produce Frictional force, since the diameter of the rotating shaft is much smaller than that of the rotor, the frictional force is much smaller than the frictional force generated by the direct contact between the spool and the solenoid wall of the solenoid electromagnet. The initial suction force of the rotor type electromagnet is large, which just meets the requirements of overcoming the back pressure and the viscous force between the valve port and the rubber seal when the gas solenoid valve is opened. The charac...
