Description
Technical field
The utility model relates to seal for pipe joints connection area, is specifically related to the sealing fastening device between a kind of pipeline and pipeline waterproof device.
Background technique
As the pipeline of transport liquid, gas; carrying out well room and the waterproofing protection such as valve, measuring instrument to it is a very important job; and for the device for pipeline waterproof; require that the sealing of himself will be got well; thus reasonable water-proof performance can be reached; further, the sealability between pipeline waterproof device and its claimed pipeline also will be guaranteed, thus realizes water-proof function.
Connection between traditional pipeline and pipeline waterproof device adopts and is rigidly connected, concrete way delivers to factory after being cut by the pipeline at scene to carry out processing with pipeline waterproof device and be connected, again the finished parts connected is transported to again after making job site carry out pipeline from newly welding recovery.
Adopt appeal method to be connected and sealed, its operation can not complete at the construction field (site), must carry out secondary transferring, cause hidden danger to pipe safety, not only time-consuming increase cost of taking a lot of work, and meanwhile, secondary welding destroys the integrity of pipeline, adds pipeline leakage point.
Model utility content
For the deficiencies in the prior art, the utility model provides the sealing fastening device between a kind of pipeline and pipeline waterproof device, solves the problem that pipeline and pipeline waterproof device carry out sealing in non-destructive situation.
For realizing above object, the utility model is achieved by the following technical programs:
A sealing fastening device between pipeline and pipeline waterproof device, is characterized in that: comprise tensioner flange, seal arrangement working pipe, U-shaped seal ring, clamping bolt; Described seal arrangement working pipe is enclosed within the outside of the pipeline that will connect, its one end is connected with pipeline waterproof device, its the other end has outwardly convex portion and is connected for being fixed with tensioner flange, the endoporus of described seal arrangement working pipe is two-part step hole, step hole near water-tight device one end is aperture, and the step hole near lug boss one end is macropore; Described U-shaped seal ring is placed in the groove formed when seal arrangement working pipe is connected with pipeline; Described tensioner flange is provided with wedge shape projection, and described wedge shape projection is wedged in U-shaped seal ring; Described tensioner flange is connected by clamping bolt with seal arrangement working pipe.
Further, the centre of described U-shaped seal ring (3) has otch.
Further, the material of described U-shaped seal ring (3) is silicone rubber.
The beneficial effects of the utility model are:
Provide the sealing fastening device between a kind of pipeline and pipeline waterproof device, its structure is simple, can at the construction field (site), do not destroy pipeline complete when namely realize sealing between pipeline and pipeline waterproof device being fastenedly connected, simple to operate and sealing effect is good.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model.
Description of reference numerals:
1, tensioner flange; 2, seal arrangement working pipe; 3, U-shaped seal ring; 4, clamping bolt; 5, pipeline; 6, pipeline waterproof device.
Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The problem sealed can not be carried out in non-destructive situation to solve pipeline and pipeline waterproof device in prior art, the utility model discloses the sealing fastening device between a kind of pipeline and pipeline waterproof device, see the sealing fastening device overall structure schematic diagram between pipeline as shown in Figure 1 and pipeline waterproof device, sealing fastening device between described pipeline and pipeline waterproof device comprises the sealing fastening device between a kind of pipeline and pipeline waterproof device, it is characterized in that: comprise tensioner flange 1, seal arrangement working pipe 2, U-shaped seal ring 3, clamping bolt 4, described seal arrangement working pipe 2 is enclosed within the outside of the pipeline 5 that will connect, its one end is connected with pipeline waterproof device 6, its the other end has outwardly convex portion and is connected for being fixed with tensioner flange 1, the endoporus of described seal arrangement working pipe 2 is two-part step hole, step hole near water-tight device 6 one end is aperture, and the step hole near lug boss one end is macropore, described U-shaped seal ring 3 is placed in the groove formed when seal arrangement working pipe 2 is connected with pipeline 5, described tensioner flange 1 is provided with wedge shape projection, and described wedge shape projection is wedged in U-shaped seal ring 3, described tensioner flange 1 is connected by clamping bolt 4 with seal arrangement working pipe 2.
Working principle of the present utility model is that to adopt take silicone rubber as the U-shaped seal ring 3 of material and the parts of other materials based on glass fibre reinforced plastics, between pipeline 5 and pipeline sealing device 6 by tensioner flange 1 and U-shaped seal ring 3 through clamping bolt 4 complete between pipeline waterproof device and pipeline in conjunction with fit sealing.During work, only slowly need tighten clamping bolt 4 and make the wedge shape projection of tensioner flange 1 mobile in U-shaped seal ring 3, make U-shaped seal ring 3 to both sides slowly tensioner, thus and pipeline 5 paste extremely, realize being tightly connected of pipeline.Meanwhile, the centre of U-shaped seal ring 3 has otch, and the wedge shape projection of tensioner flange 1 can be made more easily to move inward, and is unlikely to the structure destroying U-shaped seal ring 3; And the aperture sidewall centre of step hole has otch in seal arrangement working pipe 2, be beneficial to protection and be unlikely to destroy in the situation lower sealing device working pipe 2 of U-shaped seal ring 3 swell tension.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.
Above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
