Beschreibung
Zusammenfassung:	The ball valve comprises a valve seat, a ball valve element and a valve rod, the valve seat comprises a left valve body, a right valve body, a top cover and a bottom cover, the top cover and the bottom cover are fixedly connected with the left valve body and the right valve body through bolts, the ball valve element is located between the top cover and the bottom cover, one end of the valve rod penetrates through the top cover and then is fixedly connected with the ball valve element, and the other end of the valve rod is fixedly connected with the ball valve element. According to the self-lubricating ball valve, the graphite sealing sleeves are arranged, the graphite sealing sleeves are matched with the ball valve element, the self-lubricating effect can be achieved, abrasion between the graphite sealing sleeves and the ball valve element is reduced, meanwhile, a grease injection structure is additionally arranged, and therefore the sealing performance of the ball valve is improved. The lubricating grease ca
