Abstract
The invention discloses a steel-plastic composite tube connecting structure based on orifice flanging. The connecting structure comprises two pipelines to be connected, a bush and two flanges, wherein the two pipelines are coaxially arranged and orifices of the pipelines are opposite, two ends of the bush are respectively inserted in the orifices of the two pipelines, the flanges are respectively sleeved on the two pipelines and are connected through a bolt, the orifices of the pipelines are provided with flangings extending outwards along the radial direction of the pipelines, the middle part of the bush is provided with an annular protruding edge along the circumferential direction, the flangings on the orifices of the two pipelines abut against the annular protruding edge of the bush from the both sides, and the two flanges respectively compact the flangings on the orifices of the two pipelines from the outside to the inside. The connecting structure can use the orifice flangings as a point of strength for connection and a sealing surface, thus the connection is convenient, the pullout force resistance is strong and the sealing performance is reliable.
Description
Technical field
The present invention relates to a kind of pipe connecting structure, particularly a kind of linkage structure of steel-plastic composite pipe.
Background technique
Advantages such as steel-plastic composite pipe is a kind of emerging composite pipe tubing, and it has, and bearing capacity is strong, good corrosion resistance, linear expansion coeffcient are little at present, are applied to more and more that petroleum gas is carried, industrial and mineral is with various fields such as pipe, water drinking tube, waste pipes.
Existing steel-plastic composite pipe is straight tube structure, and the steel-plastic composite pipe of straight tube structure is carrying out having multiple linkage structure when quick-sealing connects, like internal-expansion type linkage structure, locking hood type linkage structure etc.; Wherein, the internal-expansion type linkage structure need be by the internal-expanding installation of special use, the processing of expanding in connection procedure, pipe fitting being carried out; Connect complex procedures; Implementation cost is higher, and the pulling capacity that receives of pipeline is when big, and interior bloated pipeline also is easy to generate and recovers distortion and cause pull-off; And problem such as the anti-pull-out force of locking hood type linkage structure ubiquity is more weak all can not satisfy usage requirement well.
Therefore, need to explore a kind of linkage structure of steel-plastic composite pipe, make it can satisfy the requirement of being convenient to connect, can reach effects such as anti-pull-out force is big, good seal again.
Summary of the invention
In view of this; The present invention provides a kind of steel-plastic composite pipe connecting structure based on mouth of pipe flange; This structure is through being provided with flange to the steel-plastic composite pipe mouth of pipe, and Point of Strength and sealing surface when utilizing flange to connect as pipeline reach the purpose of the big and good seal of pull-out force easy to connect, anti-.
Steel-plastic composite pipe connecting structure based on mouth of pipe flange of the present invention; Comprise that lining and two that insert respectively in two pipeline mouths of pipe at the coaxial setting and the mouth of pipe relative two pipelines to be connected, two ends are placed in the adjustable flange plate of spacing on two pipelines respectively; The mouth of pipe of said pipeline is provided with the flange that extends radially outwardly along pipeline; Said lining middle part is along circumferentially being provided with cyclic convex edge; Flange on two pipeline mouths of pipe withstands the cyclic convex edge of lining from both sides, two flange plate ecto-entads compress two flange on the pipeline mouth of pipe respectively.
Further, be respectively arranged with sealing gasket between the flange of said cyclic convex edge and two pipeline mouths of pipe;
Further, the sleeve that stretches into corresponding pipeline is set on the said sealing gasket;
Further, be provided for the groove that corresponding flange embeds on said two flange plate respectively.
Beneficial effect of the present invention: the steel-plastic composite pipe connecting structure based on mouth of pipe flange of the present invention; Comprise that lining and two that insert respectively in two pipeline mouths of pipe at the coaxial setting and the mouth of pipe relative two pipelines to be connected, two ends are placed in respectively on two pipelines and by bolted flange plate; The mouth of pipe of said pipeline is provided with the flange that extends radially outwardly along pipeline; Said lining middle part is along circumferentially being provided with cyclic convex edge, and the flange on two pipeline mouths of pipe withstands the cyclic convex edge of lining from both sides, and two flange plate ecto-entads compress two flange on the pipeline mouth of pipe respectively; This structure is with Point of Strength and the sealing surface of mouth of pipe flange as connection; Easy to connect, anti-pull-out force is strong, and sealing is reliable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below will combine accompanying drawing that the present invention is elaborated; As shown in the figure: the steel-plastic composite pipe connecting structure based on mouth of pipe flange of present embodiment, comprise that lining 2 and two that insert respectively in two pipeline 1 mouths of pipe at relative two of the coaxial setting and mouth of pipe pipeline to be connected 1, two ends are placed in the adjustable flange plate 3 of spacing on two pipelines 1 respectively, flange plate is connected to form the adjustable structure of spacing through many bolts; The mouth of pipe of said pipeline 1 is provided with the circular flange 1a that extends radially outwardly along pipeline 1; Said lining 2 middle parts are along circumferentially being provided with cyclic convex edge 2a, and the flange 1a on two pipeline 1 mouths of pipe withstands the cyclic convex edge 2a of lining 2 from both sides, and two flange plate 3 ecto-entads compress two flange 1a on pipeline 1 mouth of pipe respectively; The spacing of regulating two flange plate through bolt realizes compressing of flange plate; The Point of Strength that flange 1a connects as pipeline, its anti-pull-out force is stronger, simultaneously; Flange forms face seal, good sealing effect as the sealing surface that pipeline connects.
As the further improvement of technique scheme, be respectively arranged with sealing gasket 4 between the flange 1a of said cyclic convex edge 2a and two pipeline 1 mouths of pipe, improve sealing effect.
As the further improvement of technique scheme, the sleeve 4a stretch into corresponding pipeline is set on the said sealing gasket 4, the sealing gasket accurate positioning, and also sealing gasket is difficult for dropping when installing, and easy to operate.
As the further improvement of technique scheme, be provided for the groove that corresponding flange 1a embeds on said two flange plate 3 respectively, accurate positioning during two pipeline butt joints, convenience.
Explanation is at last; Above embodiment is only unrestricted in order to technological scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technological scheme of the present invention; And not breaking away from the aim and the scope of technological scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
