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

Abstract

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.

Description

technical field [0001] The invention relates to a vacuum pumping system based on high temperature and high pressure environment. Background technique [0002] Non-metal composite materials are pressed and formed in an autoclave. It is necessary to wrap a dense vacuum bag on the outside of the molding material, and then put it in the autoclave to achieve a high temperature and high pressure environment. In this environment, the composite material in the vacuum bag is molded The gas molecules generated and the volatile molecules of the composite material in the high-temperature environment are removed by vacuuming, and the pumping and measurement are integrated to strictly control a certain degree of vacuum and ensure that the composite material product does not produce defects such as deformation, pores, and glue. It is an autoclave, etc. A series of pressure vessels is a major difficulty in the composite molding process. At present, the device used in this technology is two...
