Abstract
The utility model discloses a connection structure of a steel plastic composite pipe based on pipe opening turning edges, which comprises two connection pipelines to be connected, a lining and two flanges. The pipelines to be connected are coaxially arranged, and pipe openings of the pipelines are opposite. Two ends of the lining are respectively inserted in the pipe openings of the two pipelines. The two flanges are respectively sleeved on the two pipelines and connected through bolts. Turning edges extending outwards along the pipelines in the radial direction are arranged on the pipe openings of the pipelines, an annular protruding edge is arranged in the middle of the lining in the circumferential direction, the turning edges on the pipe openings of the two pipelines abut against the annular protruding edge of the lining from two sides, and the two flanges respectively press the turning edges on the pipe openings of the two pipelines from outside to inside. The connection structure regards the turning edges on the pipe openings as the acting point and the sealing face for connection and is convenient in connection, high in pull resistance and reliable in sealing.
Description
Technical field
The utility model 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 utility model 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-.
The steel-plastic composite pipe connecting structure based on mouth of pipe flange of the utility model; 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.
The beneficial effect of the utility model: the steel-plastic composite pipe connecting structure based on mouth of pipe flange of the utility model; 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 utility model is further described.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below will combine accompanying drawing that the utility model 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 the technological scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technological scheme of the utility model; And not breaking away from the aim and the scope of the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
