Abstract
The utility model discloses an improve double -walled bellows interface sealing performance's novel sealing washer, it comprises sealing washer circle body and sealing washer tip, establish to saw dentate structure on sealing washer tip top, saw dentate structure top contact face is established to wide face, wide face all favours sealing washer tip homonymy. The utility model discloses not only simple structure, convenient operation, installation are swift, and it is good to be difficult for rolling, multiple layer sealing, sealing performance moreover, improves work efficiency.
Description
Technical field
The utility model relates to accepts mouth sealing device field, relates to a kind of novel seal circle improving double-wall corrugated pipe sealing joint performance specifically, being tightly connected between being applied in double-wall corrugated pipe socket end and bellmouth.
Background technology
Traditional municipal sewage treatment, the tubing that more than 95% sewerage system uses is concrete pipe, reinforced concrete pipe, cast iron pipe, because this type of tubing working procedure is more complicated, pipe joint number is more, joint is difficult to sealing, antiseep not easily processes in time, and it is easily damaged aging, accumulate over a long period and road foundation can be caused to sink, effluent seepage, cause soil property pollution, pollution of waterhead; Causing rainwater to flow in treatment plant season at rainwater, dry season sewage outflow, cannot well collect sewage.
Along with the development of plastic pipe production technology, and the high-performance that plastic pipe has compared with traditional piping material (such as concrete pipe, cast iron pipe etc.) is accepted by people gradually, national departments concerned has in succession been formulated relevant restriction and has been eliminated backward products, promotes the use of the industry policy of novel environment friendly product. In the public works of China, the application development of new type plastic pipe is very rapid, and the use cost of new type plastic pipe and traditional piping material are close to even lower. HDPE double-wall corrugated pipe, its inner wall smooth, outer wall is with the serial hollow corrugation with axes normal, structure is unique, and there is superior mechanics, physics, chemical property, it is used widely in fields such as municipal administration drainage project, farmland irrigating engineering, water delivery engineering, telecommunications engineerings, and it is listed in Ministry of Construction's scientific and technological achievement key popularized project.
At present, the most frequently used mode of connection of HDPE double-wall corrugated pipe connects for accepting Jiao Quan, accepts Jiao Quan and connects and can directly install in pipe ditch, with after bottle gouard moved by hands or handle pipe socket end cover gluing circle directly in reeve bellmouth. But, in the seal gum circle undertaking process adopted in installation process, it is easy to occur rolling about in seal gum circle lip limit, or seal gum circle top contact surface is excessively little, causes its sealing property to decline, drainage occurs, therefore, the structure of seal gum circle is further improved.
Practical novel content
In order to overcome the deficiency that above technology exists, the utility model aim to provide a kind of structure simple, quick for installation, not easily roll about, the novel seal circle of the raising double-wall corrugated pipe sealing joint performance of good seal performance.
The utility model deal with problems adopt technical scheme be: a kind of novel seal circle improving double-wall corrugated pipe sealing joint performance, it is made up of seal ring coil and sealing-ring end, top, described sealing-ring end is set to laciniation, described laciniation top contact face is set to wide face, and described wide face all favours same side, sealing-ring end.
The beneficial effects of the utility model are: the utility model is by the improvement of structure, and not only structure is simple, easy to operate, quick for installation, and not easily roll about, multi-layer sealed, good seal performance, it is to increase working efficiency.

Embodiment
In order to the technology contents of a kind of novel seal circle improving double-wall corrugated pipe sealing joint performance of the utility model, structural attitude are described in detail, below in conjunction with enforcement mode and coordinate accompanying drawing to be described further.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of novel seal circle improving double-wall corrugated pipe sealing joint performance, it is made up of seal ring coil 1b and sealing-ring end 1c. In order to improve being tightly connected of sealing-ring end 1c and flare end 2,1c top, described sealing-ring end is set to laciniation, it is achieved multi-layer sealed. In order to further make closely seamless link inside the laciniation on 1c top, described sealing-ring end and double-wall corrugated pipe flare end 2 bellmouth, described laciniation top contact face 1a is set to wide face, described wide face all favours the same side of 1c, sealing-ring end, namely with the same side of double-wall corrugated pipe flare end 2 bellmouth, just it is connected with mutually sealing to coincide with double-wall corrugated pipe flare end 2 bellmouth shape. In order to more convenient sealing-ring 1 is inserted in the tube wall gap 4a of the adjacent tube wall 4 in double-wall corrugated pipe 3a surface, 1c two sides, described sealing-ring end spacing is coincide symmetrically with adjacent tube wall 4 spacing (i.e. tube wall gap 4a) in double-wall corrugated pipe 3a surface.
The double-wall corrugated pipe seal ring installation process that the utility model improves: first, the pipe ditch dug is inserted the double-wall corrugated pipe 3a/3b needing to accept, by bottle gouard moved by hands or handle pipe, sealing-ring 1 is put in the tube wall gap 4a having between the adjacent tube wall 4 in socket end double-wall corrugated pipe 3a surface, owing to the tube wall gap 4a spacing between seal end face 1c two sides spacing with the adjacent tube wall 4 in double-wall corrugated pipe 3a surface is coincide symmetrically, therefore, seal ring coil 1b and the lower end of seal end face 1c thereof are just embedded in the tube wall gap 4a of the adjacent tube wall 4 on double-wall corrugated pipe 3a surface, play preliminary sealing effect. secondly, by to overlap in flared end 2 bellmouth that the double-wall corrugated pipe 3a socket end having sealing-ring 1 injects another double-wall corrugated pipe 3b, 1c top, described sealing-ring end is set to laciniation, it is achieved multi-layer sealed, in order to further make closely seamless link inside the laciniation on 1c top, described sealing-ring end and double-wall corrugated pipe flare end 2 bellmouth, described laciniation top contact face 1a is set to wide face, increase contact area, avoid the difficult problem rolled about in sealing-ring 1 insertion process, described wide face all favours the same side of 1c, sealing-ring end, namely with the same side of double-wall corrugated pipe flare end 2 bellmouth, just it is connected with mutually sealing to coincide with double-wall corrugated pipe flare end 2 bellmouth shape, improve the sealing property inside sealing-ring 1 and flared end 2 bellmouth further, reach best sealing effect. finally, it is cycled to repeat above mode of connection, the double-wall corrugated pipe 3a/3b radical being mounted in pipe ditch according to actual needs successively, until the length installation of actual needs.
It thus is seen that by the structure of the utility model sealing-ring being improved, not only structure is simple, easy to operate, quick for installation, and not easily roll about, multi-layer sealed, good seal performance, it is to increase working efficiency.
Above disclosed being only better embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, the equivalent variations therefore done according to the utility model claim, still belongs to the scope that the utility model is contained.
