Problems solved by technology

[0002] The Chinese Patent Gazette discloses a "vertical rotor type gas solenoid valve", whose publication number is CN101493157A. The "vertical rotor type gas solenoid valve" has the advantages of saving materials and simple structure, but due to the The sealing ring is used to seal the gas in the valve casing. Although the structure is simple, in order to ensure that there is no gas leakage after long-term work, there must be enough interference between the sealing ring and the rotor shaft. Therefore, the sealing ring It will produce greater friction and viscosity on the rotor shaft. At the same time, because the sealing ring is made of rubber and has resilience, the rotor will produce a large movement displacement hysteresis when it is adjusted back and forth. The rotor hysteresis value If the angle is above 0.2°, there will be a large hysteresis in the process of gas volume adjustment

Abstract

The invention discloses a low return difference structure for a vertical rotor gas solenoid valve. A rubber sealing ring between an original rotor shaft and a valve shell is canceled, and the gas control return difference can be reduced exponentially, so that the gas quantity of the vertical rotor gas solenoid valve is accurately adjusted. Therefore, a leakproof cover is arranged between the periphery of a vertical rotor electromagnet and the valve shell, the rubber sealing ring is arranged between the leakproof cover and the valve shell, two wiring terminals are arranged to penetrate a side wall of the leakproof cover, insulating sealing rings are arranged between the wiring terminals and the side wall of the leakproof cover, and the two wiring terminals are electrically connected with a stator coil winding lead respectively.

Description

technical field [0001] The invention relates to the technical field of gas solenoid valves, in particular to a low hysteresis structure of a vertical rotor type gas solenoid valve.
