Beschreibung
Zusammenfassung:	A valve core assembly having: a guide rod; a ball bearing; a valve head provided with a first through hole at its bottom; and a fixing block provided with a second through hole at the bottom. A first end portion of said guide rod is inserted into the ball bearing, the first through hole of the valve head and the second through hole of said fixing block in sequence, and the first end portion of the guide rod is fixedly connected to the ball bearing and the second through hole of the fixing block respectively. The structure of the valve core assembly has good gas tightness, and can reduce the wear of the valve head.
