A gas valve structure

Abstract

The utility model discloses a kind of air valve structures, including valve body, valve core, compression nut, plug, compression nut is connected on valve body by thread, plug is connected on valve body by thread, inlet chamber and outlet chamber are equipped in valve body, sealing sheet is installed on valve core, sealing ring is formed on the inner wall of outlet chamber by protruding, the end face of sealing ring and sealing sheet is tightly contacted to form end face seal by the thrust of spring;Or, the end face of sealing sheet is protruded to form sealing ring, the inner wall of outlet chamber is tightly contacted to form end face seal by the thrust of spring by sealing ring. Valve body participates in sealing, does not rely on the cooperation of compression nut and valve core, both reduces the concentricity requirement between three, and also reduces the radial static seal between compression nut and valve body.
