Embodiment:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the composite seal ring that the present invention improves, comprises a metal sealing circle body 1 and the symmetrical two ends being positioned at metal sealing circle body of two nonmetal sealing circle bodies, 2,2 ', two nonmetal sealing circle bodies; Its improvements are: described metal sealing circle body 1 encloses central authorities outside wall and is provided with fixed groove 7, and this fixed groove 7 is provided with the groove 4,4 ' and sealing surface 3,3 ' with flange seal placed for nonmetal sealing circle body successively respectively to two ends symmetry; These two nonmetal sealing circle bodies 2,2 ' are placed in the groove 4,4 ' of the nonmetal sealing circle body placement of confession that metal sealing circle body 1 is provided with respectively.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the composite seal ring that the present invention improves, wherein: it is that the angle between the inwall of this groove and groove inner bottom surface is 100 degree to 150 degree along metal sealing circle body circle wall circumferencial direction integrated groove that described metal sealing circle body 1 encloses the fixed groove 7 that outside wall, central authorities are provided with.The groove that the nonmetal sealing circle body of described confession is placed is two, these two grooves 4,4 ' are the symmetrical both sides being positioned at the fixed groove 7 be provided with outside metal sealing circle body circle wall respectively, and these two grooves are that the nonmetal seal ring shape of this groove and extrusion matches along the integrated groove of metal sealing circle body circle wall circumference circumferential direction.Be provided with two grooves placed for nonmetal sealing circle body outside described metal sealing circle body circle wall and be provided with at its both sides circle wall the sealing surface 61,62,63,64 being convenient to the extrusion of nonmetal sealing circle body and protuberance sealing respectively, sealing face is plane of inclination, and this plane of inclination and the extrusion of nonmetal sealing circle body and the angle of inclination of protuberance match.Describedly lay respectively at outside the metal sealing circle body circle wall outside away from two nonmetal sealing circle body sealing surfaces of fixed groove 7 with the sealing surface 3,3 ' of flange seal, should match with the sealing surface of flange seal and flange facing shape.Described metal sealing circle body 1 is that stainless steel is one-body molded; Described two nonmetal sealing circle bodies 2,2 ' for rubber or polyurethane material one-body molded.
When the composite seal ring that the present invention improves uses: adopt metallic material to make upper flange 8 and lower flange 5, make flange hardness higher than metal o-ring 1.During installation, first upper flange 8 lifting is fixed, again by composite sealing ring from bottom to top close to upper flange 8, when composite sealing ring moves straight up, the outer end of its fixed groove 7 promotes the inside of the elastic seal ring locating piece 9 indentation upper flange 8 in two upper flanges, the metal sealing circle body of seal ring to be composite one of them when contacting with upper flange 8 sealing surface with the sealing surface of flange seal, composite sealing ring motion puts in place, elastic seal ring locating piece 9 in upper flange 8 ejects under the effect of its elastic supporting member for supporting optical member, extend the inside of fixed groove 7, after cancelling external force, upper flange 8 can carry composite sealing ring and jointly moves to above lower flange 5 position, composite sealing ring is transferred on lower flange 5, to metal sealing circle body, another just completes installation process after contacting completely with lower flange 5 with the sealing surface of flange seal.Finally, use press machine to apply thrust load, active force is applied to upper flange 8 and lower flange 5, realize the compressive strain of deep water replaceable composite sealing ring under water, and then realize sealing.By passing into high pressure oil to the upper flange 8 and the inner confined space of lower flange 5 that complete sealing, and carry out pressurize, the performance of test deep water replaceable composite sealing ring under water, as shown in Figure 4.Adjustment press machine thrust load and suppress pressure, observes leakage situation, when the pretightening force of press machine reach 36t, high pressure oil pressure reaches 35MPa, pressurize 1 hour, pipeline does not leak, and proves that sealing is effective.
The working principle of the composite seal ring that the present invention improves and advantage:
1, the sealing surface 3,3 ' that metal sealing circle body and flange carry out sealing coordinates with upper flange 8 and lower flange 5 sealing surface respectively, can seal the high-pressure oil gas of inside; Nonmetal sealing circle body 2,2 ' is separately fixed in the groove 4,4 ' that metal sealing circle body is provided with, sealing surface 61,62,63,64 place sealed with nonmetal sealing circle body that after pressurization, the extrusion of nonmetal sealing circle body and protuberance are positioned at groove both sides, the nonmetal sealing circle body at this place is subject to upper flange 8 and lower flange 5 motion extruding, great resiliently deformable can be produced, thus can seal the seawater of outside; What upper flange 8 inside was arranged have elastic carrying capacity and telescopic seal ring locating piece 9 is positioned at the fixed groove 7 of the composite seal ring of improvement, upper flange and lower flange and sealing circle is locked, and facilitates the underwater installing/dismounting of sealing circle.
When 2, using, the sealing surface 3 of metal sealing circle body and flange seal and nonmetal sealing circle body contact with lower flange 5 with upper flange 8 simultaneously, form metal to metal seal and nonmetal-metal sealing, thus realize composite seal, improve leakage efficiency, save usage space.
The fixed groove of the composite seal ring 3, improved can match with the seal ring positioning means that flange is arranged, and make seal ring comparatively conveniently can install under water, dismantle and change, operation facilitates efficiency high.
4, the composite seal ring improved and the sealing surface 3,3 ' of flange seal are symmetricly set on outer end, metal sealing circle body fixed groove both sides, can prevent high-pressure oil gas from leaking out to device external.
5, the sealing surface that metal sealing circle body and nonmetal sealing circle body seal is symmetricly set on the metal sealing circle body circle wall of groove both sides, when the composite seal ring work improved time, outside seawater can infiltrate into nonmetal sealing circle body sealing surface place, the extruding that now nonmetal sealing circle body is subject to external force can produce distortion, whole nonmetal sealing circle body and flange tightly fit together, reach sealing effect, effectively can stop the infiltration of seawater to device interior.
6, fixed groove is arranged on the central position in composite seal face, and with the elastic seal ring locating piece acting in conjunction in upper flange, can realize the function of location composite seal ring, space saved by this project organization this, is beneficial to the realization of locating function.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
