Abstract
The invention discloses a water lubrication stern shaft sealing device. A sealing base is fixed to the position above a gland. A sealing pneumatic tyre is arranged on the inner side of the sealing base and provided with a pneumatic tyre inner ring. A pipe connector A is fixedly arranged above the sealing base. A fixed ring is arranged on the outer side of the sealing base. A sealing ring A is arranged between the sealing base and the fixed ring. A pipe connector B is arranged above the fixed ring. The other end of the fixed ring is connected with a movable ring. The movable ring is connected with a rubber ring through a transmission pin, the other end of the rubber ring is connected with a bushing ring, and a sealing ring B is arranged between the bushing ring and the rubber ring. The section of the rubber ring is in an arch shape. A releasing connecting pipe is further arranged below the sealing device. The water lubrication stern shaft sealing device has the beneficial effects that the service life is long, sediment invasion and water impurity scaling are effectively prevented, and meanwhile the sealing effect is good.
Description
Technical field
The present invention relates to technical field of ships, particularly to a kind of Water lubricating stern shaft sealing device.
Background technology
At some containing the big and impure many waters of silt ratio, the problem that Water lubricating stern shaft sealing device runs into
It is that the rotating seat in ring portion is dynamic close with the pushing sleeve (being also referred to as lining in industry) in elastic thrust compensation part
There is gap and junction between seal point, use some months or after the longer time, the most easily thin by silt
Grit enters or water impurity easily forms incrustation scale in dynamic sealing point junction, forms part wears at dynamic sealing point
Lost efficacy with elastic thrust partial spring thrust-compensating effect, caused seepage and the dynamic and static ring sealing of water between seal point
Leak between pair.
For solving this problem, it is common practice to boats and ships shutdown maintenance, utilize Water lubricating stern shaft sealing device
In false pregnancy due to stagnation of QI part blocks outboard water, pull down ring portion remove incrustation scale, sand grains, change rotating ring the most again
Between seat and pushing sleeve, the O in dynamic sealing point, the most often affects boats and ships normal/cruise, brings certain
Economic loss.
Summary of the invention
It is long that the technical problem to be solved is to provide a kind of service life, effectively prevent silt from invading and
Water impurity fouling, the simultaneously Water lubricating stern shaft sealing device of good sealing effect.
The technical scheme is that
A kind of Water lubricating stern shaft sealing device, gland is fixedly arranged above seal receptacle, is provided with sealing inside seal receptacle
False pregnancy due to stagnation of QI, seals and is provided with false pregnancy due to stagnation of QI internal ring on false pregnancy due to stagnation of QI, and seal receptacle is fixed above is provided with pipe joint A, outside seal receptacle
Side is provided with stationary ring, is provided with sealing ring A between seal receptacle and stationary ring, and stationary ring is provided above pipe joint B,
The stationary ring other end is connected with rotating ring, and rotating ring is connected with rubber ring by trundle, the rubber ring other end and grommet
Connect, between grommet and rubber ring, be provided with sealing ring B；Described rubber ring cross sectional shape is arch form；Seal dress
Put lower section and be additionally provided with drainage adapter.
The bore of the relative aperture pipe joint B of pipe joint A of the present invention is little.
Stationary ring of the present invention is open circles ring type.
The advantage of a kind of Water lubricating stern shaft sealing device of the present invention is, service life is long, the most anti-
Only silt invades and water impurity fouling, simultaneously good sealing effect.
Accompanying drawing explanation
The present invention is described further below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present invention.
1, gland, 2, seal receptacle, 3, pipe joint A, 4, pipe joint B, 5, stationary ring, 6, rubber ring,
7, grommet, 8, clamp ring, 9, sealing ring B, 10, trundle, 11, rotating ring, 12, sealing ring A, 13,
Seal false pregnancy due to stagnation of QI, 14, false pregnancy due to stagnation of QI internal ring, 15, drainage adapter.
Detailed description of the invention
A kind of Water lubricating stern shaft sealing device, gland 1 is fixedly arranged above seal receptacle 2, arranges inside seal receptacle 2
Having sealing false pregnancy due to stagnation of QI 13, seal and be provided with false pregnancy due to stagnation of QI internal ring 14 on false pregnancy due to stagnation of QI 13, seal receptacle 2 is fixed above to be provided with
Pipe joint A3, is provided with stationary ring 5, is provided with sealing ring between seal receptacle 2 and stationary ring 5 outside seal receptacle 2
A12, stationary ring 5 is provided above pipe joint B4, and stationary ring 5 other end is connected with rotating ring 11, and rotating ring 11 passes through
Trundle 10 is connected with rubber ring 6, and rubber ring 6 other end is connected with grommet 7, grommet 7 and rubber ring 6
Between be provided with sealing ring B9；Described rubber ring 6 cross sectional shape is arch form；It is additionally provided with below sealing device
Drainage adapter 15.
The bore of the relative aperture pipe joint B4 of pipe joint A3 of the present invention is little.
Stationary ring 5 of the present invention is open circles ring type.
When being embodied as, rotating ring rubbing surface after being sleeved on stern tube shaft by rotating ring body portion, is made to fit with stationary ring face,
Then use the arch rubber ring in specific purpose tool compression rotating ring body, make between rubber ring, to form a certain amount of bullet
Property compensate thrust, then be fixed on stern tube shaft together with rubber ring with clamp ring with grommet, such rotating ring body is formed for
One integral part, middle dynamic sealing point-free, effectively prevent silt invasion and impurity fouling.Rubber ring cross section
Being shaped as arch form is so that rubber ring has a certain amount of elastic compensating power.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every profit
Equivalent structure or the equivalence flow process made by description of the invention content convert or are directly or indirectly used in other
Relevant technical field, is the most in like manner included in the scope of patent protection of the present invention.
In sum, the advantage of a kind of Water lubricating stern shaft sealing device of the present invention is, service life is long,
Effectively prevent silt from invading and water impurity fouling, simultaneously good sealing effect.
