Abstract
The present invention relates to a ship sealing device, in particular to the improvement of a ship oil lubricating sealing device. A self pressure regulating ship oil lubricating sealing device of the present invention comprises a lip-shaped sealing ring, a sealing base for fixing and clamping the lip-shaped sealing ring and an oil chamber, wherein the oil chamber is communicated with a floating barrel which floats at the sea and is communicated with the atmosphere. The present invention can regulate the oil pressure of the oil chamber at any time to enable the front-rear pressure difference of the lip-shaped sealing ring closed to zero, the self pressure regulating ship oil lubricating sealing device is easy to carry out, and the operation is reliable.
Description
Technical field
The utility model relates to ship sealing device, relates in particular to the improvement of ship oil lubricating sealing device.
Background technique
Lubricated sealing device of oil is one of boats and ships seal arrangement commonly used, is used to generally prevent that seawater from entering hull or device interior from the boats and ships running shaft, and the quality of its sealability directly has influence on the safe operation of boats and ships, is the important component part of boats and ships.Lip-type packing of the ring-type that present lubricated sealing device of oil is mainly made by rubber (claiming the hot Rec department seal ring that sprinkles again) and clamping be the fixing sealing seat of lip-type packing and oil pocket formation also.The preceding basil one side (hereinafter to be referred as the front side) of lip-type packing is in the face of seawater, thereafter the basil one side (hereinafter to be referred as rear side) and sealing seat constitute oil pocket together, be marked with lubricant oil in the oil pocket, its effect is: 1, the lip for lip-type packing partly provides lubricant oil, prevents that lip from partly dry grinding; 2, partly dispel the heat for lip; 3, reduce the pressure reduction of lip-type packing front and back side.Because lip-type packing is made by rubber, deformation takes place easily, when the seawater pressure of lip-type packing front side is excessive, can wash lip open and cause seal failure, this takes place in the ocean engineering vehicle of deep ocean work especially easily, thereby the oil pressure in the oil pocket can offset a part of seawater pressure, the pressure reduction before and after the minimizing lip-type packing.But accomplish that in real ship difficulty in service the front and back pressure reduction of lip-type packing is less and stable, this also is that lubricated sealing device of oil causes one of reason of leakage.
The model utility content
At the above-mentioned deficiency of existing in prior technology, technical problem to be solved in the utility model is that a kind of self pressure regulating ship oil lubricating sealing device will be provided, and can adjust the oil pressure of oil pocket at any time, makes lip-type packing front and back pressure reduction approach zero, implement easily again, reliable.
In order to solve the problems of the technologies described above, the scheme of the utility model technical solution problem is: a kind of self pressure regulating ship oil lubricating sealing device, comprise lip-type packing, the fixing also sealing seat and the oil pocket of this lip-type packing of clamping, described oil pocket and the floating drum that floats on the sea and be communicated with atmosphere are communicated with; This oil pocket is connected with the top of the oil feeding reservoirs of sealing, and the bottom of oil feeding reservoirs is connected with floating drum with flexible pipe through U type pipe.
After adopting such scheme, because the front side of described lip-type packing is communicated with seawater, the rear side of described lip-type packing is an oil pocket, and oil pocket is communicated with floating drum on floating on the sea, be marked with lubricant oil in the floating drum, thereby the pressure reduction before and after the lip-type packing is exactly the pressure reduction between the lubricant oil in seawater and the floating drum, irrelevant with the submarine site of running shaft, the pressure reduction that has effectively guaranteed the lip-type packing both sides is equal substantially, again owing to the proportion of sea water specific gravity greater than lubricant oil, when the height of lubricant oil in the floating drum is higher than the sea, can make the pressure reduction of lip-type packing front and back approach zero, lip-type packing is worked in very little pressure reduction environment, deformation does not take place, improved the sealability of lubricated sealing device of oil.
Cover is arranged at the floating drum top, and the breathing pipe that outlet is downward and be communicated with atmosphere is arranged on the cover, prevents that seawater is splashed in the floating drum, connects by flexible pipe between oil pocket and the floating drum.The flexible pipe of floating drum bottom also can provide the airtight oil feeding reservoirs of lubricant oil to be communicated with by U type Guan Yuxiang oil pocket, prevents that the seawater that enters floating drum from scurrying into oil feeding reservoirs, and " U " shape pipe can be special U-shaped pipe, also can be made of hose bending.The one-way valve of make-up oil is installed on the oil nozzle of oil feeding reservoirs.Floating drum floats over the sea, and being fixed on the hull of can fluctuating.
Flexible pipe also can be fixed on the side of floating drum.
The utility model self pressure regulating ship oil lubricating sealing device is particularly suitable for the operation and the navigation of ocean engineering vehicle, although the underwater operation degree of depth reaches about 60 meters sometimes deeply, but floating drum floats on the sea, and it is influenced by wave highly only, can play the effect of automatic adjustment oil pocket oil pressure preferably.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the structural principle schematic representation of the utility model self pressure regulating ship oil lubricating sealing device.
Embodiment
Among Fig. 1, be fixed to sealing seat 2 clampings and fixedly lip-type packing 1 on the hull, the lip of lip-type packing 1 is fitted on the rotary sleeve 7, the front of lip-type packing 1 is a seawater, the back is an oil pocket 8 of filling with lubricant oil, and oil pocket 8 is connected with the bottom of airtight oil feeding reservoirs 3, and the bottom of oil feeding reservoirs 3 is connected with an end of flexible pipe 6 through " U " shape pipe 4, the other end of flexible pipe 6 is connected with the bottom of the floating drum 5 that is marked with lubricant oil, floating drum 5 relocatable being fixed on the hull.Because floating drum 5 is communicated with oil feeding reservoirs 3, thereby floating drum 5 can make lessly, only plays automatic Regulation, and is as for the lubricant oil that loses in the lubricated sealing device of oil working procedure, then additional by the lubricant oil in the bigger oil feeding reservoirs 3 of capacity.
When boats and ships rise or descend,,, can not take place that lip-type packing 1 is out of shape and the phenomenon that causes seal failure so the pressure reduction of lip-type packing 1 front and back side also is more or less the same because floating drum 5 oil pressure and the seawater pressure that provide is more or less the same in running job.
The effect of " U " shape pipe is to stop the water breakthrough that is splashed in the floating drum 5 to go into oil feeding reservoirs 3, keeps the purity of lubricant oil in the oil feeding reservoirs 3, and the lubricant oil in the oil pocket 8 can be lubricated the lip of lip-type packing 1, dispel the heat, and makes lip-type packing 1 proper functioning.
The installed in front of lip-type packing 1 has gas sealing mechanism 9, is used for stoping seawater to be invaded when lubricated sealing device of oil lost efficacy.
The one-way valve (not drawing among fuel filler neck and the one-way valve figure) of make-up oil is installed on the fuel filler neck at oil feeding reservoirs (3) top.
The another lip-type packing that is positioned at lip-type packing 1 back is standby lip-type packing.
