Abstract
The utility model relates to a pipeline flaring connection structure, in particular to a flaring connection structure for a polyvinyl chloride pipe. A closed short pipe (13) is inserted into each of thickened sections (7) of two corresponding pipelines (6); rubber rings (14) are arranged between horn mouths (9) corresponding to the two pipelines (6) and the closed short pipes (13); and flanges (12) outside the thickened sections (7) of the two pipelines (6) are fastened by nuts (15) after at least six screws (10) passes through penetrating holes (11) in the flanges (12). In the flaring connection structure, the wall of the polyvinyl chloride pipe is molded by a die to form a flaring structure into which the closed short pipes can be inserted and which can be used for fastening the rubber rings; the aim of compact connection is fulfilled by fastening of the flanges and the screws; and the phenomena of falling, breakage, water leakage and gas leakage of the conventional pipe can be avoided effectively.
Description
[technical field]
The utility model relates to a kind of pipeline enlarging linkage structure, especially relates to the enlarging linkage structure of a kind of polyvinyl chloride pipe (PVC).
[background technique]
At present, the connecting means of known underground mine use PVC (PVC) pipeline is the connecting means of the civilian UPVC water pipe of transplanting, commonly used is to insert connection method after an end of pipeline expands into straight mouth or R mouth, another kind is in the bonding peaceful flange connection method of pipe ends, because the environment very severe under the coal mine, pipeline can't effectively be fixed, and the working pressure of pipeline is very unstable, the operating mode humidity, reasons such as narrow space, pipe coupling is prone to and comes off after causing existing method to connect, fracture, the gas leak phenomenon that leaks has increased inconvenience and great potential safety hazard to producing under the coal mine.
[summary of the invention]
For overcoming the deficiency of existing pipe plugging technology, the utility model provides a kind of enlarging linkage structure of polyvinyl chloride pipe, the enlarging linkage structure of described polyvinyl chloride pipe, utilize mould that the tube wall typing of polyvinyl chloride pipe is formed the enlarging structure that can insert the sealing short tube and fasten rubber ring, by the close-connected purpose of fastening realization of flange and screw; The pipeline that the has overcome existing mode effectively gas leak phenomenon that comes off, ruptures, leaks.
For achieving the above object, the utility model adopts following technological scheme:
A kind of enlarging linkage structure of polyvinyl chloride pipe, by two pipelines being heated the back respectively and inserting mould respectively, make the typing of two pipelines, the place of connecting of two pipelines forms the horn mouth of corresponding pipeline overstriking section and end respectively, in two corresponding pipeline overstriking sections, insert a sealing short tube respectively, rubber ring is set at corresponding horn mouth of two pipelines and sealing between the short tube, fastening by nut the flange of two pipeline overstriking section outsides is passed perforation on the flange by at least six screws after.
The enlarging linkage structure of described polyvinyl chloride pipe is provided with the increased diameter inclined-plane of transition between pipeline and overstriking section.
The enlarging linkage structure of described polyvinyl chloride pipe, described rubber ring outer rim both sides are respectively equipped with corresponding bell-mouthed inclined-plane.
Owing to adopted technique scheme, of the present utility model have a following beneficial effect:
The enlarging linkage structure of polyvinyl chloride pipe described in the utility model, by the tube wall heating of heating equipment with polyvinyl chloride pipe, insert mould shape then, make pipeline form the width that can be inserted in the sealing short tube after withdrawing from mould, and use rubber ring the enlarging structure of joint is airtight, fastening by flange and screw then, make two flanges form the power of pushing to the middle part to flange, force rubber ring to fill up two relative horn mouths, realized the tight connection purpose of two pipeline joints; The pipeline that the has prevented existing mode effectively gas leak phenomenon that comes off, ruptures, leaks; The utlity model has and connect that technology is simple, cost is lower, sealing effect is better than existing structure.

[embodiment]
Can explain the utility model in more detail by the following examples, the utility model is not limited to the following examples, and open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope;
The enlarging linkage structure of the polyvinyl chloride pipe described in 1～6 in conjunction with the accompanying drawings, by two pipelines 6 being heated the back respectively and inserting mould 4 respectively, make 6 typings of two pipelines, the place of connecting of two pipelines 6 forms the horn mouth 9 of corresponding pipeline 6 overstriking sections 7 and end respectively, between pipeline 6 and overstriking section 7, be provided with the increased diameter inclined-plane 8 of transition, in two corresponding pipeline 6 overstriking sections 7, insert a sealing short tube 13 respectively, between two pipelines, 6 corresponding horn mouths 9 and sealing short tube 13, rubber ring 14 is set, described rubber ring 14 outer rim both sides are respectively equipped with the inclined-plane of corresponding horn mouth 9, and are fastening by nut 15 by perforation 11 backs that at least six screws 10 pass on the flange 12 at the flange 12 of two pipelines, 6 overstriking sections, 7 outsides.
Implement the enlarging linkage structure of polyvinyl chloride pipe described in the utility model, 2,3,4 as can be known in conjunction with the accompanying drawings, at first flange is enclosed within on the pipeline 6, utilize ring heater heating pipe 6 then, pipeline 6 after the heating inserts the seeker 1 of mould 4, mould inclined-plane 5, expansion are inserted pipeline 6 successively through the mould inclined-plane 5 of section 2 and afterbody one side, treat to extract mould 4 after pipeline 6 solidifies, pipeline 6 ends are formed and mould 4 essentially identical shapes; According to another pipeline 6 ends of aforementioned processing; Horn mouth 9 places after the processing insert sealing short tube 13, then by instrument planing horn mouth 9 and the interface that seals short tube 13, ring docks with sealing short tube 13 respectively in the both sides of rubber ring 14, the both sides external of rubber ring 14 is inserted respectively between sealing short tube 13 and the horn mouth 9, the perforation 11 that utilizes screw 10 to insert two flanges just can by nut 15 is fastening.
Mould of the present utility model 4 rear portions are provided with arm; Because mould 4 does not belong to protection domain of the present utility model; therefore the utility model is not further set forth and is limited mould 4 structures; because pipe hot melting document formerly is more,, any pipe hot melting mode all belongs to protection domain of the present utility model so realizing pipeline 4 linkage structures in the utility model scope.
The utility model does not describe part in detail and is prior art.
