Connector connects the second sealing ring bracket, the second sealing ring carriage outer end fixed connection and sealing ring, and the fitting of sealing ring end face is set
Support ring connects transmission ring in support ring；Emergent seal is installed between the mounting seat and the first sealing ring bracket, it should
Anxious seal crowds around into full circle by the arc structure that several valves are divided equally, and can radially be moved per valve arc structure.
As a further improvement on the present invention, the connector includes elastic compensating body, the first main card circle, the second main card circle
And elastic compensating body one end is clamped in the card slot of the first sealing ring bracket by adjusting bolt, the first main card circle, the second master
The elastic compensating body other end is clamped in the card slot of the second sealing ring bracket by retainer ring, and the first main card circle, the second main card circle pass through
Adjusting bolt is adjacent.
As a further improvement on the present invention, it is connected between the sealing ring and the second sealing ring bracket by positioning pin
It connects.
As a further improvement on the present invention, the second sealing ring bracket circle end face connection splash guard.
As a further improvement on the present invention, arc structure described in every valve passes through emergent adjusting screw, emergent compression spiral shell
Mother is connected to the first sealing ring bracket.
As a further improvement on the present invention, the mounting seat endoporus forms card slot, sets air bag in card slot, air bag leads to
It crosses trim ring to be fixed, conduit is formed on air bag, bracing ring is arranged in conduit.
The technical effects of the invention are that：The present invention is wear-resistant, and the mal-conditions such as the silt in vessel motion environment are fitted
Stress is stronger.Extend the service life of stern shaft seal gland, reduce the frequency of maintenance of ship shaft sealing, extend ship's navigation
Time.With adjustable emergent sealing function, emergency mechanism can Reusability, easy to adjust, long lifespan, when making ship navigation
Emergency capability greatly enhances, and ensures that naval vessel can continue to keep to navigate by water for a long time in oceangoing voyage after the failure of stern shaft seal main body.
