Abstract

Abstract: With the development of space technology, the requirement of pressure control, depressurization and repressurization for pressure sensitive components are proposed. In other words, the vacuum thermal test equipment should have the function of depressurization, repressurization and stable pressure, which can control the pressure. According to the principle of dynamic balance and automatic control technology, the principle of the pressure regulating system of vacuum thermal test equipment and design method are proposed. The results show that the equipment meets the requirement of the design, which ensures the pressure experiment carried out sucessfully.

Key words: vacuum thermal test, pressure regulating system, automatic control
