Description
Technical field
The utility model belongs to underwater equipment technical field, is related to a kind of underwater sealing structure of anti-scratch sealing ring.
Background technique
Underwater equipment (such as underwater sealing cabin) is the equipment to work in an underwater environment, can be realized underwater sealing and
Pressure-bearing, can carry Various Components inside equipment, the sealing of such underwater equipment it is just particularly important.It is related to seal form at present
Type it is very much, wherein using sealing ring be sealed the most extensively.
Sealing ring major part material all uses the rubber material of various characteristics, and the reliability of sealing performance and service life is very
It is high；It is especially rigorous using the sealing structure of sealing ring in design, many design standards are followed, can just sealing structure be made to reach most
Good state.Since sealing ring is the complexity in rubber material and sealing structure, so rubber material touches in assembling process
It will appear unpredictable scuffing risk to sharp seamed edge, if cannot find in time, seal failure risk is high.
Summary of the invention
The utility model intends to solve the technical problem by providing a kind of underwater sealing structures of anti-scratch sealing ring, make with holes
Mating surface and sealing surface separate, avoid the risk that sealing ring is scratched.
The utility model is to be achieved through the following technical solutions:
A kind of underwater sealing structure of anti-scratch sealing ring, including the shell and plug to match, wherein case inside is set
There are stationary plane and sealing surface, the internal diameter D1 of stationary plane is greater than the internal diameter D2 of sealing surface, is also provided with fixation hole on stationary plane；Plug
Including the fixed part to match with stationary plane, and the sealing to match with sealing surface；Seal groove is offered on sealing,
Inside it is embedded with sealing ring；The fixation blind hole to match with fixation hole is offered on fixed part.
The internal diameter D1 of the stationary plane is 1mm or more bigger than the maximum outside diameter under sealing ring free state.
When the described plug seal casinghousing, sealing passes through stationary plane Shi Yuqi clearance fit, arrives at sealing surface Shi Yuqi
It is fitted close；Sealing and stationary plane are fitted close, and fixed blind hole is aligned with fixation hole.
The sealing ring being embedded on the sealing is not compressed when passing through stationary plane, is just compressed when into sealing surface.
Compared with prior art, the utility model has technical effect beneficial below:
Due to the edge of shell in the prior art and the fixation hole of plug fastening be it is sharp, had chamfering sharp
Side, and chamfering also increases difficulty of processing and cost；After sealing ring is mounted to plug, plug seals when passing through fixation hole
Circle has certain decrement, and the dynamics that the rebound characteristics of sealing ring make it have nature to expand in the normal orientation of mating surface is sliding
Scuffing will be constituted to sealing ring surface by crossing sharp side, caused sealing ring to damage when assembling, cannot be found in time, seal
Effect substantially reduces, and the risk for greatly depositing just leakage is brought so that making underwater equipment at work has great failure risk
Unnecessary loss and disaster.
The underwater sealing structure of anti-scratch sealing ring provided by the utility model is filling stationary plane and sealing surface with holes
Timing is staggered, and the diameter of the stationary plane with fixation hole is greater than the free outer diameter of sealing ring, makes sealing ring through not pressed when via hole
Contracting (does not have decrement), while sealing ring and mating surface with holes are clearance fits, and the two would not have scraping collision in assembly,
Fixation hole scratches sealing ring when to prevent assembly, has prevented the presence of the risk for scratching sealing ring in underwater equipment sealing structure,
It ensure that the reliability of underwater equipment.
Detailed description of the invention
Fig. 1 is the existing easy underwater sealing structural schematic diagram for scratching sealing ring；
Fig. 2 is the underwater sealing structural schematic diagram that the utility model prevents from scratching sealing ring.
Wherein, 1 is plug, and 2 be shell, and 3 be sealing ring, and 4 be fixation hole, and 5 be stationary plane, and 6 be sealing surface.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, it is described be explanation to the utility model without
It is to limit.
Referring to Fig. 1, in existing underwater sealing structure, is realized and sealed using sealing ring 3 between shell 2 and plug 1, it is close in figure
Sealing internal diameter D3 is the two tolerance fit dimension, guarantees the reasonable decrement of sealing ring；It is also needed in figure after shell 2 and plug 1 assemble
Shell 2 and plug 1 is set to form connection fastening relationships at fixation hole 4 with fastened by screw；As can be seen from Figure 1 have on sealing surface solid
Determine hole, be installed into the assembling process of shell 2 behind 1 set of upper seal 3 of plug, sealing ring 3 enters after shell 2 into compression shape
State has potential bounce, and when sealing ring is slipped over as at figure A, sealing ring by compression meeting nature due to being expanded, with fixation hole 4
Sharp edges friction, scratches sealing ring herein, and then continues toward 2 mounted inside of shell, and sealing ring has damaged at this time,
The external world is not easy to find, will cause sealing hidden danger.
The sealing surface dismounting with fixation hole prevents from scratching sealing ring in order to prevent, and the utility model improves sealing mechanism,
So that mating surface and sealing surface equipped with fixation hole is staggered in assembly, occurred on the same face to avoid drawing in assembly
Wound.
Referring to fig. 2, a kind of underwater sealing structure of anti-scratch sealing ring, including the shell 2 and plug 1 to match, wherein
Stationary plane 5 and sealing surface 6 are equipped on the inside of shell 2, the internal diameter D1 of stationary plane 5 is greater than the internal diameter D2 of sealing surface 6, goes back on stationary plane 5
Offer fixation hole 4；Plug 1 includes the fixed part to match with stationary plane 5, and the sealing to match with sealing surface 6；It is close
Seal groove is offered in envelope portion, is inside embedded with sealing ring 3；The fixation blind hole to match with fixation hole 4 is offered on fixed part.
The internal diameter D1 of the stationary plane 5 is 1mm or more bigger than the maximum outside diameter under sealing ring free state.
When the described plug seal casinghousing, sealing passes through 5 Shi Yuqi clearance fit of stationary plane, when arriving at sealing surface 6 with
It is fitted close；Sealing and stationary plane 5 are fitted close, and fixed blind hole is aligned with fixation hole 4.
The sealing ring being embedded on the sealing is not compressed when passing through stationary plane 5, is just pressed when into sealing surface 6
Contracting.
As shown in Fig. 2, being the stationary plane equipped with fixation hole at B, internal diameter D1 is greater than seal inner diameter D2, and D1 is than close
Maximum outside diameter under seal free state is greater than 1mm or more, makes sealing ring 7 by not having decrement when fitting surface in this way, simultaneously
The mating surface of sealing ring and fixation hole is clearance fit, improves the sealing structure wind that sealing ring is scratched in assembly or disassembly
Danger；Guarantee that its sealing ring is not scratched in the dark；Prevent the presence of the risk for scratching sealing ring in underwater equipment sealing structure, has guaranteed
The reliability of underwater equipment.
