Abstract
The utility model relates to a lighter gas valve assembly, which is characterized in that the overall appearance of the gas valve assembly is a cylinder with leveling surface and a buckling structure in hermetic combination with the gas box outlet is also provided. The admission gear is an adjustment free constant current admission gear. The adjustment free constant current admission gear is adopted in the admission gear of the utility model. Thus the arrangement of adjustment screw for the adjusting of the gas output is not required. The buckling method is adopted for the connection between the admission gear and the gas box so that the inner joint and the ultrasonic welding can be cancelled and the assembly process is simplified. Moreover because the dynamic seal is converted to a static seal, the sealing performance is greatly enhanced.
