FIELD: nuclear engineering.
SUBSTANCE: device can be used for connecting filter to ventilation system operating in hostile medium. Device has cylindrical case intended for placing filter inside it. Cylindrical case has its second end fixed onto flange of ventilation system. The first end of case is used for mounting counter-flange which is hold flexible under axial strength by means of pressure sustain aids. Device also has bushing which is tightly fixed in align to the case. Counter-flange is mounted around the bushing for slide along its axis. Pressure sustain aids are placed onto bushing. Three rollers are tightly fixed to the bushing which rollers form protrusions of the bushing directed outside. Cam is mounted onto bushing at specific part of its length. Cam enclosing the bushing is made in form of a ring having triple guide in form of part of spiral. Corresponding rollers enter mentioned guides. Turning movement of the roller provides axis movement of the counter-flange. Aids for turning drive of the cam are also provided.
EFFECT: efficient seal of ventilation system; keeping filter motionless at seismic shocks.
