Vacuumizing system based on high-temperature and high-pressure environment

The invention discloses a vacuumizing system based on a high-temperature and high-pressure environment. The vacuumizing system comprises a sampling and testing integrated joint, wherein the sampling and testing integrated joint is a Y-shaped three-way joint, a lower interface of the three-way joint is hermetically connected with a vacuum bag through a connecting structure, and two upper interfaces of the three-way joint are respectively connected with a vacuumizing pipe and a vacuum measuring pipe through joints; and the vacuumizing pipe and the vacuum measuring pipe are respectively connected with a vacuumizing system and a vacuum measuring system. The system is good in state at high temperature and high pressure, reliable in performance and accurate in measured vacuum data; , use and replacement are convenient, the KF standard component is low in price, and the service life of the KF standard component is longer than that of an original vacuumizing and vacuum measuring system. 本发明公开了一种基于高温高压环境下的抽真空系统，包括抽测一体
