Description
Technical field
The utility model relates to ship sealing device, relates in particular to the improvement of boats and ships pressurized seal device.
Background technique
Pressurized seal device peculiar to vessel is boats and ships such as all kinds of civilian boats, military affairs seal arrangements commonly used, the supporting uses of main sealing device such as normal and lubricated sealing device of oil, water lubrication seal arrangement, mechanical seal device can be used for the sealing of the running shafts such as electric plating propulsion axle of screw shaft of ship, ocean engineering boats and ships.Present pressurized seal device is by the hermetic seal seat, be installed in the ringwise opening air bag of making by rubber in the hermetic seal seat, be inlaid in the branch compression ring in the opening air bag, and the gland assembly that the opening air bag is fixed and is sealed in the hermetic seal seat constitutes, the gland assembly is made of airtight capping and threaded connector, airtight capping is fitted on the airtight capping supporting surface of hermetic seal seat, by threaded connector airtight capping is fixed on the airtight capping supporting surface, the air inlet nozzle that is communicated with the opening air bag is installed on the perisporium of hermetic seal seat, the hermetic seal seat is processed with the axis hole that allows running shaft pass along its axial end, the other end is provided with towards periphery the lip limit that being used to of protruding install the ring of hermetic seal seat, the hermetic seal seat ring is embraced running shaft and is installed on the hull, usually when being installed, the hermetic seal seat overlaps for axis and the rotating shaft axis that guarantees the hermetic seal seat, on hull, be provided with the positioning boss of ring, it highly is generally about 5～12mm, so that the hermetic seal seat is installed on the hull after being nested on the positioning boss again, the boats and ships main sealing device is encircled the running shaft lining vertically and is installed on the hermetic seal seat, the internal diameter of hermetic seal seat split shed air bag is slightly larger than the external diameter of running shaft, the annular sealing surface of opening air bag does not contact with running shaft, promptly do not seal, have only and when the running shaft main sealing device lost efficacy, just enable pressurized seal device, inflate by the air inlet nozzle on the hermetic seal seat, the pressurized air that enters in the hermetic seal seat enters opening air bag inside through a minute compression ring, the opening air bag that rubber is made expands rapidly, and make the annular sealing surface of opening air bag be pressed on the running shaft, prevent that seawater from entering in the cabin.
In the at present common pressurized seal device peculiar to vessel, the axial length of hermetic seal seat external form is bigger than normal, this Cu alloy material that makes equipment itself consume is more, cost is also high, the real ship of such pressurized seal device is installed the back and also can not brought big facility for installation, maintenance, has not yet to see the data or the product of the pressurized seal device peculiar to vessel of compact more practicality.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of compact type pressurized seal device peculiar to vessel, and this compact type pressurized seal device axial length peculiar to vessel is little, and it is few to consume copper material, and it is little to take the hull space, easy to maintenance.
The scheme that the utility model solves its technical problem is: a kind of compact type pressurized seal device peculiar to vessel, comprise the hermetic seal seat, be installed in the opening air bag of built-in minute compression ring in this hermetic seal seat, and the gland assembly of fixing and seal described opening air bag, one end of this hermetic seal seat is processed with axis hole, the other end is provided with the ring lip limit of protruding towards periphery, be processed with the installation end face on plane radially on the described lip limit, the intermediate portion of this hermetic seal seat is processed with the airtight capping supporting surface on plane radially, be installed with described gland assembly on this airtight capping supporting surface, the distance between described installation end face and the described airtight capping supporting surface is at the height L of the positioning boss of the inwall reservation on described lip limit
TAxial thickness L with described gland assembly
YAnd the height L of the positioning boss reserved with the inwall on described lip limit
TWith the 1.2 axial thickness L that multiply by described gland assembly
YAnd between.
Owing to adopt such scheme, after the real ship of compact type pressurized seal device peculiar to vessel is installed, the distance of positioning boss is exactly the axial thickness of gland assembly basically on airtight capping supporting surface and the hull, fit up gap when real ship is installed between positioning boss and the airtight capping exterior edge face is generally 2mm～5mm, when adopting bolt to connect, the axial thickness of gland assembly is exactly the height sum of head of the bolt of the thickness of airtight capping and fixed air sealing cover, particularly when adopting sunk screw to fix and compress the hermetic seal seat, the axial thickness of gland assembly is exactly the thickness of airtight capping, distance between the exterior edge face of airtight capping and the hull boss is littler, this makes the axial length of gas sealing mechanism diminish, saved the copper material that the hermetic seal seat consumes in a large number, both reduced cost of material, make equipment compacter again, the hull space that takies is littler, and convenient staff carries out the maintenance and repair work of equipment in the cabin.Owing to the size decreases of hermetic seal seat, shorten the time of gold machining again, saved processing cost.
Gas sealing mechanism belongs to not the emergent seal arrangement that often uses, and so its rate of fault is very low, just dismantled during general time-based maintenance, thereby the fit up gap between positioning boss and the airtight capping exterior edge face is less than normal, and the conventional maintenance that does not influence gas sealing mechanism maintains.
On the other hand, the height on the lip limit of hermetic seal seat is relevant with the gross mass of pressurized seal device with the size of width, along with consuming copper material, reduces the hermetic seal seat, quality descends, the height on the lip limit of hermetic seal seat and the physical dimension of width also can reduce accordingly, the copper material that this can save lip limit part again further reduces cost.
