Beschreibung
Zusammenfassung:	The novel high-pressure stop valve comprises a valve body and a valve clack, the valve body is connected with a valve clack driving mechanism through a pressing cover, the valve clack driving mechanism comprises a transmission rod arranged on the pressing cover in a penetrating mode, the transmission rod is connected with the pressing cover through an upper pressing cover and a threaded sleeve which are arranged on the transmission rod in a sliding and sleeving mode, and the upper pressing cover is arranged between the pressing cover and the transmission rod in a sealing mode. The threaded sleeve is arranged on the gland in a sleeving mode and tightly presses the upper gland towards the gland. The three-layer sealing design is adopted at the transmission driving end, the sealing reliability of the valve in the operation process is guaranteed, and the requirement for high pressure is met; the double-layer sealing design is arranged on the outer side of the valve clack, so that the sealing reliability is furthe
