Abstract

The utility model provides a clamping connector of large-caliber PE pipes, and belongs to the technical field of machine manufacturing. Annular protruding shoulders with trapezoidal cross sections are arranged on the outer pipe walls of the end portions of the two PE pipes, and the side faces, close to the end portions of the PE pipes, of the protruding shoulders are perpendicular to the bottom faces of the protruding shoulders. At the positions of the protruding shoulders of the end portions of the PE pipes, an upper half clamp body and a lower half clamp body are respectively provided with two trapezoidal clamping grooves, and clearances are arranged between the inner surfaces of the clamping grooves and the bottom faces of the protruding shoulders. The parts, between the clamping grooves, of the clamping bodies are middle clamp bodies, and the middle clamp bodies are attached to the outer circumferences of the combination positions of connecting pipes. Annular elastic gaskets are arranged at the combination positions of the connecting pipes. Due to the fact that the protruding shoulders and the clamping grooves are in male-female coupling, the fact that axial displacement does occur to the two large-caliber PE pipes is guaranteed, and a connecting state is maintained. Along with the screwing of clamping bolts, axial extruding force is formed on the elastic gaskets, and the large-caliber connecting pipes can be effectively sealed. The clamping connector has the advantages of being simple in manufacturing, good in sealing performance and long in service life.

Description

A kind of thimble connector of heavy caliber PE pipe
Technical field
The utility model relates to a kind of pipe joint, particularly connects the thimble connector of heavy caliber PE pipe, belongs to machinery manufacturing technology field.
Background technique
Known major diameter PE pipe is for facilities such as living water, rock gases, compactness requires high, conventionally the Placement of PE pipeline has welding, flange to connect or clip connected, welding mode is generally carried out under the good condition of construction environment, if run into rainfall abundant summer, construction causes pipeline to expose in addition, and the accident of pipe leakage happens occasionally, and leak, probably cause immeasurable economic loss, environmetal impact, obviously very unfavorable to the maintenance work of pipeline.China National Fire Academy general bureau regulation, the connection of pipe diameter >=lOOmm answers segmentation to adopt flange or clip connected.For heavy caliber PE pipeline, if adopt flange to connect, flange is corroded because pipeline is embedded under ground piping for a long time, and sealability declines, and also shorten at double working life.Yet employing clip connected, lacks the corollary equipment of manufacturing clip in the market, has limited the widespread adoption of the clip connected of PE pipeline, cause trouble to the repair work after pipe leakage accident occurs.Industry is expected a kind of appearance of manufacturing the Petrochemical Pipe Joints of simple, easy to operate, good airproof performance.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of thimble connector of heavy caliber PE pipe of easy to assemble, simple to operate, good airproof performance.
The utility model is to realize by the following technical solutions above-mentioned purpose: a kind of thimble connector of heavy caliber PE pipe, includes: connecting tube, first clip body, second clip body, and connecting tube is comprised of two sections of identical PE pipes of inside and outside diameter; It is trapezoidal annular convex shoulder that the outer tube wall of two sections of PE tube ends is provided with cross section, and described convex shoulder is vertical with convex shoulder bottom surface near PE tube end one side.The convex shoulder position of PE tube end, first clip body, second clip body are respectively equipped with two trapezoidal draw-in grooves, and the internal surface of draw-in groove and convex shoulder bottom surface are provided with gap.The part that clip body is positioned between two draw-in grooves is middle card hoop body, middle card hoop body and the laminating of connecting tube junction excircle.Connecting tube junction is provided with the resilient pad of ring-type.The both sides lower limb of first clip body is fixed with two upper card ears, and the both sides top edge of second clip body is fixed with under two and blocks ear, on described upper card ear and described lower card ear, coordinates and is provided with clamping bolt.
When two sections of PE pipes are during as connecting tube, first clip body, second clip body are on the excircle that upper and lower symplex structure is arranged on two sections of PE tube ends just, the middle card hoop body arranging and connecting tube junction excircle, perpendicular to the convex shoulder side of convex shoulder bottom surface, are that face contacts on it.Along with screwing of clamping bolt, the two ends of two clip bodies move closer under tension force effect, and the internal surface of draw-in groove and the gap of convex shoulder bottom surface diminish gradually on the one hand, and pressure between clip body and connecting tube is increased; To being positioned over the resilient pad of connecting tube junction, form axial extruding force on the other hand, thereby connecting tube is connected and effective sealing well.
Innovation of the present utility model is the corresponding position at the end of two sections of PE pipes and clip body, be respectively equipped with convex shoulder and the draw-in groove of male and female coupling, guarantee when connecting tube diameter is larger, there is not axial displacement and keep coupled condition in two sections of PE pipes, connecting tube junction is provided with the resilient pad of ring-type simultaneously, along with screwing of clamping bolt, the resilient pad being placed therein is formed to axial extruding force, can realize the effective sealing of heavy caliber connecting tube.
The utlity model has the advantage of manufacturing simple, good seal performance, long service life.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
The present embodiment comprises connecting tube 3, first clip body 1, second clip body 8, and connecting tube 3 is comprised of two sections of identical PE pipes of inside and outside diameter; It is trapezoidal annular convex shoulder 6 that the outer tube wall of two sections of PE tube ends is provided with cross section, and convex shoulder 6 is vertical with convex shoulder bottom surface 5 near the convex shoulder side 4 of PE tube end.Convex shoulder 6 positions of PE tube end, first clip body 1, second clip body 8 be respectively equipped with two trapezoidal draw-in grooves 6 ', draw-in groove 6 ' internal surface and convex shoulder bottom surface 5 be provided with gap.Clip body be positioned at two draw-in grooves 6 ' between part be middle card hoop body 11, middle card hoop body 11 and connecting tube 3 junction excircles laminatings.Connecting tube 3 junctions are provided with 7 of the cushions of ring-type.The both sides lower limb of first clip body 1 is fixed with two upper card ears 2, and the both sides top edge of second clip body 8 is fixed with under two and blocks ear 9, on upper card ear 2 and lower card ear 9, coordinates and is provided with clamping bolt 10.
