Abstract:
According to the long-life,light-weight and xenon working medium requirements proposed by the system, a new type of Bang-Bang solenoid valve was specially designed. By adopting the design scheme of “Spring and S-spring” and selecting the proper parameters of sealing pressure(5.70～6.72 MPa), matching gap(0.12～0.14mm), spool stroke(0.20mm)and others, the Bang-Bang solenoid valve has successfully passed the assessment of environmental tests such as vibration, shock(the maximum magnitude 1 600 g), acceleration(20 g), thermal vacuum(10～75℃)and thermal cycle(-10～+75℃)as well as a million times of life test verification. The parameters such as leak rate and response time of the valve were stable before and after the experiment, which greatly met the system requirements.
