Connecing seal casinghousing, described curve housing has interior sealing concave ring groove, and described seal casinghousing has external seal concave ring groove, described
External seal concave ring groove connect triangle slot, described triangle slot connects triangle slotting ring, described triangle slotting ring
Having interior circular hole, described interior circular hole connects jack, and described interior circular hole connecting cylinder inserted link, described cylinder inserted link has horizontal stroke
Jack, described horizontal jack connects spring, and described spring connects location bar, and described location bar is inserted along described jack
Entering, eject fixing, described cylinder inserted link connection triangle plate, described triangle plate connects exterior seal ring.
Described screw pump repaiies rear safety sealing device, the described external seal scrobicular ring described in exterior seal ring insertion
Groove, in the described triangle slot described in the insertion of triangle plate, described interior sealing concave ring groove connects inlays circular groove, described
Inlay magnetic sheet in circular groove connects, described interior magnetic sheet connects outer magnetic sheet, and described outer magnetic sheet connection inner seal ring, described is interior
In interior sealing concave ring groove described in sealing ring insertion.
Described screw pump repaiies rear safety sealing device, and described seal casinghousing connects seal cap, described sealing
Housing and described sealing lid all insert mobile jib, described upper pump case bonding pad case, described stuffing box connect described in close
Capsule body is also fixed by screw.
Beneficial effect:
1. inner seal ring can be fixed therein by the interior sealing concave ring groove that this utility model uses, will not be due to external force
Extrude and deform；Exterior seal ring can be fixed therein by external seal concave ring groove, also will not deform due to the extruding of external force, close
Seal effective.
2. this utility model use triangle slot, triangle slotting ring, interior circular hole, jack, cylinder inserted link, horizontal jack,
Spring, location bar, triangle plate with the use of, make being completely embedded between exterior seal ring and seal casinghousing, firmly, improve
The stability sealed and fastness.
3. this utility model use circular groove, interior magnetic sheet, outer magnetic sheet with the use of, make between inner seal ring and curve housing
Connection very firm, the sealing effectiveness after maintenance is the best.
4. this utility model uses spring, location bar can be firmly fixed the company of cylinder inserted link and triangle slotting ring
Connect, it is ensured that the fastness that exterior seal ring is installed, improve the performance of sealing.
