Abstract
The utility model discloses a conveniently dismountable long pipeline expansion joint, belongs to the technical field of pipe joints, and aims at solving the problem of bend deformation or breakage of a pipeline due to the action of internal stress of expansion and contraction of the pipeline joint in the prior art. The long pipeline expansion joint comprises a sleeve pipe sleeved at the pipeline joint, wherein the inner diameter of the sleeve pipe is gradually reduced from the two ends to the middle in the axial direction; the outer diameter of the pipeline is smaller than the inner diameter of the sleeve pipe; asbestos ropes wound on the pipeline are arranged in the two ends of the sleeve pipe respectively; a pressure cover is also pressed on the two ends of the sleeve pipe; the pressure cover is axially provided with a pipeline receiving hole; and the diameter of the pipeline receiving hole is greater than the outer diameter of the pipeline. Compared with the prior art, the long pipeline expansion joint has the benefits as follows: the long pipeline expansion joint is simple in structure and convenient to dismount; when the pipeline is deformed due to the action of internal stress of expansion and contraction, the asbestos ropes are also deformed, so that the water seepage at the pipeline joint is avoided and the pipeline vibration transmission is reduced through the asbestos ropes; and the long pipeline expansion joint is suitable for high-vibration and high-deformation long pipeline connection places.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of long pipeline expansion joint of easy accessibility.
Background technique
In people's daily production and life, various pipelines are transport of water, gas necessary tool.Often need the pipeline end-to-ends of following to realize long-distance transportation in the remote transportation more, common pipeline Placement has screwed connection, flange connection, clip connected etc. in the prior art, but above-mentioned Placement is and is rigidly connected, under temperature variation causes situation that pipeline expands with heat and contract with cold, can not regulate voluntarily, cause pipe bending distortion or fracture easily, its drawback is particularly outstanding.For avoiding pipe coupling place to occur leaking, seal ring is installed in pipe coupling place of being everlasting in the prior art additional, but the deficiency that walks of each assembly in actual applications, the compressibility of seal ring is not high, and sealing effect is unsatisfactory.
The model utility content
The purpose of this utility model provides a kind of long pipeline expansion joint of easy accessibility, solved in the prior art pipe coupling position because of the internal stress effect of expanding with heat and contract with cold, and the problem that causes pipe coupling place easily to seep water and leak has the advantage of good sealing effect, easy accessibility.
The purpose of this utility model is achieved in that the long pipeline expansion joint of easy accessibility, comprise the sleeve pipe that is sleeved on pipeline junction, the internal diameter of described sleeve pipe shrinks to the middle part from two-port gradually along axial direction, the external diameter of described pipeline is less than the internal diameter of described sleeve pipe, be respectively equipped with the asbestos rope that installs around on described pipeline in the two-port of described sleeve pipe, also press on the two-port of described sleeve pipe and be provided with gland, described gland offers the tubing containment hole along axial direction, and the diameter in described tubing containment hole is greater than the external diameter of described pipeline.
The utility model is when installing and using, earlier be set with gland at two pipelines to be connected, then casing pipe sleeve is loaded on wherein on the pipeline, re-lay another root pipeline, sleeve pipe is moved to the joint of two pipelines, on two pipelines, twine asbestos rope more respectively, and with gland asbestos rope is pushed to sleeve pipe, at last gland is fixedlyed connected with sleeve pipe.Compared with prior art, the beneficial effects of the utility model are: simple in structure, easy accessibility, when pipeline deforms because of the internal stress effect of expanding with heat and contract with cold, asbestos rope is distortion thereupon also, avoiding pipe coupling place that infiltration takes place leaks, and asbestos rope can effectively slow down pipe vibration, is applicable to that the long pipeline of high vibration, high amount of deformation connects the place.
As further improvement of the utility model, the two ends of described sleeve pipe are respectively equipped with fastening flange, offer the attachment hole that the flange hole with described fastening flange is complementary on the described gland, be provided with seal washer and fixedly connected by tight fixed bolt between described fastening flange and the gland.Adopt flanged connecting structure, firm and reliable connection, convenient disassembly and can regulate the compaction degree of gland by regulating tight fixed bolt.
As further improvement of the utility model, the inboard working surface of described gland is provided be used to the boss that compresses that compresses described asbestos rope, describedly compresses boss ringwise.The setting that compresses boss is mainly used in asbestos rope is pushed to sleeve pipe, makes the asbestos rope in the sleeve pipe compress compacting, guarantees the sealing of pipe coupling place.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 sleeve pipe; 101 fastening flanges; 2 pipelines; 3 asbestos ropes; 4 glands; 401 compress boss; 5 seal washers; 6 tight fixed bolts.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, comprise the sleeve pipe 1 that is sleeved on pipeline 2 joints, the internal diameter of sleeve pipe 1 shrinks to the middle part from two-port gradually along axial direction, the external diameter of pipeline 2 is less than the internal diameter of sleeve pipe 1, be respectively equipped with the asbestos rope 3 that installs around on pipeline 2 in the two-port of sleeve pipe 1, also press on the two-port of sleeve pipe 1 and be provided with gland 4, gland 4 offers the tubing containment hole along axial direction, and the diameter in tubing containment hole is greater than the external diameter of pipeline 2.The inboard working surface of gland 4 is provided be used to what compress asbestos rope 3 and compresses boss 401, compresses boss 401 ringwise.The two ends of sleeve pipe 1 are respectively equipped with fastening flange 101, offer the attachment hole that the flange hole with fastening flange 101 is complementary on the gland 4, are provided with seal washer 5 and fixedly connected by tight fixed bolt 6 between fastening flange 101 and the gland 4.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technological scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characteristicss wherein, these replacements and distortion are all in protection domain of the present utility model.
