TIGHTNESS CONTROL DEVICE

摘要

FIELD: physics. ^ SUBSTANCE: proposed device comprises one vacuum chamber separated from controlled medium by hydrogen-permeable membrane and communicated with vacuum magneto-charged pump, as well as extra vacuum chamber separated from medium by hydrogen-permeable membrane and communicated with vacuum metre. Vacuum gate is connected between main and extra vacuum chambers. Controlled medium is fed to vacuum chambers by incoming flow head. Recuperator is used for heating purposes. Hydrogen concentration in circuit is controlled is performed by intermittent comparison of magneto-charged pump current readings with those of vacuum metre. ^ EFFECT: uptightness control in initial period. ^ 2 cl, 2 dwg
