Embodiment
As shown in Figure 1 to Figure 3, rudder stock seal arrangement, is comprised of stuffing seal, V-shaped seal ring seal arrangement, three part tandem arrangement of sand prevention coil apparatus;
Described stuffing seal comprises filler 3 and Gland 5, and described V-shaped seal ring seal arrangement comprises V-shaped seal ring 16 and V-seal ring support 17, and described sand prevention coil apparatus comprises sand prevention circle 1 and sand prevention circle gland.
Sand prevention circle 1 and the first sand prevention circle gland 2 are enclosed within on rudder stock 23, be arranged on left side out of my cabin on 25 rudder seal casinghousings 24, mainly prevent that in seawater, impurity enters rudder stock seal arrangement, filler 3 is arranged in rudder seal casinghousing 24, transition plate 20 is enclosed within on rudder stock 23, by the second screw 22 and packing ring 21, be fixed to rudder seal casinghousing 24 right sides, double-screw bolt 4 is tightened and is arranged on transition plate 20, on each double-screw bolt 4, be inserted in round nut 8 respectively, on adjustable material filling gland 5, packing twice the 2nd Ο type circle 13 into is then enclosed within on double-screw bolt 4, on each double-screw bolt 4, be inserted in small gear 6, round nut 8 is spun on small gear 6, round nut 8 is loaded onto the first screw 9 and is prevented that round nut from getting loose, on adjustable material filling gland 5 right sides, put gearwheel 7, with all small gear engagements, and rotate flexibly.In adjustable material filling gland 5 endoporus, pack in order the first trim ring 14, V-shaped seal ring 16, the second trim ring 15, V-seal ring support 17 into, sealing gland 11 is loaded onto to a Ο type circle 10 afterwards and adjustable material filling gland screw attachment, again sand prevention circle 1 and the second sand prevention circle gland 12 use Bolt Connection to sealing gland 11, right side sand prevention circle is mainly used in preventing in cabin the dirty rudder stock seal arrangement that enters on 26 rudder stocks.
Described V-seal ring support 17 reinstalls in adjustable material filling gland 5 after loading onto in advance V-shaped seal ring 16, the 3rd Ο type circle 18 and the 4th Ο type circle 19.
The first described trim ring 14 withstands in the V-type groove of right side V-shaped seal ring 16, this is fixed, V-shaped seal ring 16 has also been installed on the right side of the second trim ring 15 one, and right side V-shaped seal ring is whole to be arranged in V-seal ring support 17, and V-seal ring support 17 can be interior unsteady at adjustable material filling gland 5.
This rudder stock seal arrangement is usingd formation of sealing component (V-shaped seal ring) as primary seal, seals under normal circumstances, has packing seal as emergent sealing simultaneously, when primary seal loses efficacy, as emergent sealing, uses.
Primary seal of the present invention: adopt twice Ο type circle between adjustable material filling gland and rudder seal casinghousing, carry out static seal; Between adjustable material filling gland and rudder stock, adopt twice V-shaped seal ring with together with Ο type circle carry out motive sealing, the seawater that stop to see through filler enters in cabin.For adapting to the variation at relative rudder seal casinghousing center, rudder stock center, prevent that rudder stock and seal arrangement from carrying out hard friction, during design, second V-shaped seal ring, the 3rd Ο type circle the 4th Ο type circle are designed to floating type, be that seal ring and the second trim ring 15 pack into can be along in the V-seal ring support of rudder stock radial floating, its radial floating value is 2mm.
Emergent sealing of the present invention: fill up filler at rudder seal casinghousing endoporus, reinstall adjustable material filling gland.Have and compress and the adjustable material filling gland of corrective action is compressed by the double-screw bolt of several interlocks, to realize evenly, to compress stably, to adjust filler, make filler bring into play optimum effect.Real ship will unclamp half-turn by small gear after adjustable material filling gland axial compression filler while installing again, makes filler axially leave certain compression surplus; While using emergent sealing, while rotating one of them small gear, can all the other small gears be rotated by gearwheel simultaneously, can make small gear drive this gearwheel evenly to move along special-purpose double-screw bolt simultaneously, driven adjustable material filling gland evenly to move, made the compression of uniform filling or unclamp.
Sand prevention coil apparatus: respectively establish dustproof, sand prevention circle together at bow, stern end, make seal arrangement can keep static sealing when water surface state is changed filler, hard-pressed bale, on rudder stock, prevents that dust, silt from entering seal arrangement simultaneously.
This seal arrangement is comprised of packing seal, floating type V-shaped seal ring seal arrangement, three part tandem arrangement of sand prevention coil apparatus, can effectively reduce the risk that seal arrangement leaks, and after improving, is convenient to personnel's operation.
