Fig. 1 is the utility model structural representation;
Wherein, 1-steel cylinder, 2-upper flange, 3-lower flange, 4-step, 5-ring-shaped groove I, 6-ring-shaped groove II, 7-hole for injecting glue, 8-venthole, 9-installing hole.
Embodiment
Below in conjunction with accompanying drawing the compound external insulation outlet of the utility model sleeve pipe is described in further detail.
As shown in Figure 1, the utility model comprises a steel cylinder 1, and described steel cylinder is good to adopt epoxy glass fiber reinforced plastic cylinder, is provided with a upper flange 2 and a lower flange 3 respectively in the upper and lower part of epoxy glass fiber reinforced plastic cylinder 1.Upper and lower flange 2,3 is made for good to adopt nonferrous materials, upper and lower flange 2,3 is provided with a step 4 near on the internal diameter of end face of flange, when upper and lower flange is installed in the upper and lower end of epoxy glass fiber reinforced plastic cylinder 1, the step 4 of upper and lower flange withstands on the end face of epoxy glass fiber reinforced plastic cylinder 1 just, and epoxy glass fiber reinforced plastic cylinder 1 has been played positioning action.
Be provided with some road ring-shaped groove I5 at the internal diameter upper edge of upper and lower flange 2,3 axially spaced-apart, the cross section of ring-shaped groove 4 is circular arc as far as possible.Corresponding with the ring-shaped groove I5 on the upper and lower flange 2,3, on epoxy glass fiber reinforced plastic cylinder 1, also be processed with measure-alike ring-shaped groove II 6, when cooperating, the two can form the rounded seal groove of a ring cross-section, in seal groove, can pour into fluid sealant.
In order to guarantee the flowability in the fluid sealant filling process, the diameter at the two ends of the ring-shaped groove II 6 that is provided with on epoxy glass fiber reinforced plastic cylinder 1 is respectively less than the diameter at epoxy glass fiber reinforced plastic cylinder 1 middle part, like this when with upper and lower flange 2,3 heating collars on epoxy glass fiber reinforced plastic cylinder 1 time, the paragraph that ring-shaped groove II6 is not set on the epoxy glass fiber reinforced plastic cylinder 1 will form interference fit with upper and lower flange 2,3 inner surfaces, and epoxy glass fiber reinforced plastic cylinder 1 is provided with the matched in clearance that the paragraph of ring-shaped groove II6 will form broad with upper and lower flange 2,3 inner surfaces.Upper and lower flange 2,3 radially be provided with hole for injecting glue 7 and venthole 8, in the gap that ring-shaped groove I5, ring-shaped groove II 6 form, pour into fluid sealant with convenient.
In order to guarantee the connectivity robustness of interference fit paragraph, can on ring flange 2,3 and epoxy glass fiber reinforced plastic cylinder 1, be relatively set with installing hole 9, by fixture (, but being not limited thereto) that upper and lower flange and steel cylinder 1 is fastening such as rivet.
Be a specific embodiment below:
Upper and lower flange 2,3 internal diameter height overall 130mm, car goes out six roads (being not limited thereto) ring-shaped groove I 5 in the long scope of 100mm, and groove is rounded down, and same position is cut the ring-shaped groove II 6 of same structure size on the epoxy glass fiber reinforced plastic cylinder 1 that matches with it.The outside dimension of epoxy glass fiber reinforced plastic cylinder 1 upper and lower end 100mm length is than the little 2～3mm of upper and lower flange 2,3 internal diameter sizes, and epoxy glass fiber reinforced plastic cylinder 1 all the other external diameters are identical with upper and lower flange 2,3 internal diameter sizes, but the above matching allowance of 0.05mm is arranged, thereby guarantee upper and lower flange 2,3 and the long interference fit of epoxy glass fiber reinforced plastic cylinder 1 local 30mm, form good cooperation location.Because the six road ring-shaped groove I 5 at matched in clearance place and six road ring-shaped groove II 6 are corresponding one by one, constitute tight closed chamber, the inner filling fluid sealant, form six road sealing barriers behind the sealing glue solidifying, and epoxy glass fiber reinforced plastic cylinder 1 combines together with upper and lower flange 2,3, have higher intensity, thoroughly solved the air-tightness problem of compound external insulation outlet sleeve pipe partial structurtes.
When from the hole for injecting glue 7 of upper and lower flange 2,3 to seal groove that ring-shaped groove I 5 and ring-shaped groove II 6 form and gap during the perfusion fluid sealant, fluid sealant is in barotropic state, bubble can be drained from venthole 8, thereby has guaranteed that no bubble is residual in seal groove and the gap.After the bubble emptying, steam vent is blocked, hole for injecting glue is blocked with the same manner, through after a while, and the fluid sealant full solidification, thus finished overall structure.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present utility model.
