description The invention discloses a high-pressure gas quick valve which comprises a valve body, a valve deck, a ball body, a valve seat and a valve rod. The ball body is connected and fixed through fixing shafts on the upper side and the lower side; compared with a floating ball valve structure, the high-pressure gas quick valve has the advantages of being low in torque and accurate in ball body position positioning; the valve rod is connected with the ball body by adopting a cylindrical positioning pin, so that the high-pressure gas quick valve is high in overall connecting strength, small in clearances, and suitable for quick and high-frequency open and close connection condition design; self-lubricating bearings are arranged at the matched rotating part of the valve rod and the valve body and thematched rotating part of a lower valve shaft and the ball body, so that the high-pressure gas quick valve has the advantages of low friction coefficient, small mounting space and the like; a shiftingfork type pneumatic actua
