Description
Technical field
The utility model relates to a kind of pipeline plugging air bag.
Background technique
Pipeline plugging air bag is used for pipeline, culvert water delivery, blowdown, removes the maintenance of becoming silted up, when the gas pressure in shutoff air bag reaches regulation requirement, shutoff air bag fills up whole conduit section, the frictional force of utilizing pipeline plugging air bag wall and pipeline to produce is blocked and is leaked, thereby reach in target pipeline section, by inflation, current are blocked fast, reached the object without infiltration.
In actual applications, especially in the operation of drainage pipe closed-water test, usually run into because of inspection socket bore less, common air bag is not easy to fill in the problem of pipeline, this just needs a kind of volume to be less than after inspection socket and inflation again can be tightly and the larger product of pipeline laminating, patent 200520105041.3 has well solved this problem, but the lower end mouth of the patented product is passed through only for a screw, be limited to used mould, cylindrical shell and end can only be separated to moulding man-hour and dock at two again adding, belong to secondary forming process, because the cylindrical shell of rubber cured, rubber molecular chain due to joint after post forming does not interweave, therefore the gas leakage of coming unglued is easily caused at this position, air bag can not normally be used, post forming also can increase cost of labor, the today constantly raising at labor wage cost, greatly increased undoubtedly expense.
Model utility content
The utility model provides a kind of can realize cylindrical shell once-through processing, the pipeline plugging air bag of good airproof performance.
The technological scheme that the utility model adopts is:
The limit rope that the utility model comprises cylindrical shell, is arranged at the valve of cylindrical shell upper end-hole, is arranged at the sealing cover of cylindrical shell lower end mouth and connects described cylindrical shell upper end-hole and sealing cover, the lower end of described cylindrical shell is provided with raised line, described sealing cover comprises interior sealing cover and external sealed lid, on described interior sealing cover, be provided with the groove corresponding with described raised line, described external sealed covers and is provided with the groove corresponding with described raised line, between described interior sealing cover and external sealed lid, be provided with screw, and clamp by outer nut.
Raised line described in the utility model is ring rib.
Cylindrical shell described in the utility model be shaped as elliposoidal, the middle part of described cylindrical shell is provided with convex annular band.
Cylindrical shell upper end-hole described in the utility model is provided with the upper retaining ring that connects limit rope, is provided with the lower retaining ring that connects limit rope on described interior sealing cover.
Screw described in the utility model and interior sealing cover connection arrange inner nut.
The diameter of the lower end mouth of cylindrical shell described in the utility model is not less than 20mm.
The technique effect of technological scheme that the utility model adopts is as follows.
Cylindrical shell lower end mouth of the present utility model is provided with raised line, and inside and outside sealing cover and raised line corresponding section are provided with groove, after cylindrical shell inflation, between raised line and groove interlock tightr, by cylindrical shell lower end and coordinating of end cap realizing tight seal.Because lower end mouth diameter is larger, can make the internal mold of split pass through, thereby realize the once-through of cylindrical shell, metalwork sealing for bottom after cylindrical shell moulding, and this technological scheme can effectively reduce production process, increases work efficiency and cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the accompanying drawings, retaining ring, 5 interior sealing covers, 6 external sealed lids, 7-1 screw, 7-2 outer nut, 7-3 inner nut, 8 raised lines, 9 protruding bands under 1 cylindrical shell, 2 valves, 3 limit ropes, the upper retaining ring of 4-1,4-1.
Embodiment
As shown in Figure 1, the limit rope 3 that the utility model comprises cylindrical shell 1, is arranged at the valve 2 of cylindrical shell 1 upper end-hole, is arranged at the sealing cover of cylindrical shell 1 lower end mouth and connects described cylindrical shell 1 upper end-hole and sealing cover, the lower end of described cylindrical shell 1 is provided with raised line 8, described sealing cover comprises interior sealing cover 5 and external sealed lid 6, on described interior sealing cover 5, be provided with the groove corresponding with described raised line 8, on described external sealed lid 6, be provided with the groove corresponding with described raised line 8, between described interior sealing cover 5 and external sealed lid 6, be provided with screw 7-1, and clamp by outer nut 7-2.Described cylindrical shell 1 is elastic cylinder, and described sealing cover is metallic sealed cover.
Raised line 8 described in the utility model can be for being evenly distributed on the point-like of cylindrical shell, banded raised line, as long as can realize with groove on sealing cover, match and play sealing effect, continuous ring rib preferably, due to large with the area of contact of groove, sealing effect is best.
Screw 7-1 described in the utility model and interior sealing cover 5 connections arrange inner nut 7-3, can further clamp interior sealing cover 5 and raised line 8, increase the tightness of the two; Screw 7-1 and inner nut 7-3 and interior sealing cover 5 threes are welded with solder joint, increase tightness.
Cylindrical shell 1 described in the utility model be shaped as elliposoidal, also comprise that middle part is for cylindricality, both sides are the shape with the date core shaped of tapering; The middle part of described cylindrical shell 1 is provided with convex annular band 9, can strengthen and the frictional force that needs the tube wall of shutoff pipeline, strengthens plugging effect.
Cylindrical shell 1 upper end-hole described in the utility model is provided with the upper retaining ring 4-1 that connects limit rope 3, on described interior sealing cover 5, be provided with the lower retaining ring 4-2 that connects limit rope 3, limit rope for limit the utility model when inflation to longitudinal stretching, limit rope can be various material, can be iron chains, can be also high strength woven fabric.
The diameter of the lower end mouth of cylindrical shell 1 described in the utility model is not less than 20mm, because cylinder body bottom outlet is amplified, reached the bore that can be applicable to the demoulding, therefore cylindrical shell can be realized once-through, after cylindrical shell moulding, bottom is passed through seal cap sealing again, make it to become a complete finished product, compared to existing product, reduced the splicing of an end cap sulfuration and cylindrical shell and end cap, can improve 50% above manufacturing efficiency, because cylindrical shell adopts once-through, air bag head and cylindrical shell are sulfided into as a whole, between molecular chain, had and interweaved, tightness and link strength have all had large increase.Due to structure of the present utility model, can meet the requirement of cylindrical shell one-shot forming technique simultaneously, therefore can be cost-saving, thus realize the once-through of cylindrical shell, and after cylindrical shell moulding, bottom seals with metalwork, avoided carrying out in existing product the gas leakage hidden danger that post forming brings
This technological scheme can effectively reduce production process, increases work efficiency and cost-saving.
