โฆ Synopsis
The present note describes the design of valve possessing high dynamic properties and extended operational feasibilities, which is intended to protect the cryostats of superconducting (SC) magnets against overpressure. The opening pressure of the valve is dependent on the pressure rise rate in the magnet cryostat. For the pressure rise rate ranging from 2 to 100 bar/s the opening pressure varies from 19 bar to 5 bar. The developed units of the valve have been tested in the valve prototype under real operating conditions.
