Abstract: Based on the characteristics of helium, the requirements of helium making device for excellent sealing performance, and the economy of liquid helium resources, taking the triple eccentric butterfly valve as the research object, the design of the sealing ring for helium making device was explored and studied from many aspects. Firstly, a variety of seal solutions were tested to explore their advantages, disadvantages, and limitations. Then, a design of metal skeleton rubber sealing ring was proposed to effectively solve the vacuum sealing problem in the structure of the triple eccentric butterfly valve. The design was experimentally and theoretically verified from the aspects of tightness, working torque and lifetime. Finally, the overall economy based on the design was described. This design of the metal skeleton rubber sealing ring provides a relatively perfect scheme for the sealing requirement of regulating butterfly valve in helium production device at room temperature.

Key words: vacuum valve, tri-eccentric butterfly valve, vacuum sealing structure, vacuum skeleton sealing ring
