Abstract
The utility model discloses a retractable joint pipe, belongs to the technical field of pipeline connecting parts, and aims to solve the problem that a pipe joint has high probability of water leakage and water seepage due to an internal stress effect of thermal expansion and contraction at a pipe joint part in the prior art. The retractable joint pipe comprises an elastic hose of which two ends are respectively connected with the pipe joint, wherein two end ports of the elastic hose are respectively connected with connecting flanges; ring-shaped connecting parts which are integrally arranged with the connecting flanges are arranged inside the working surfaces of the connecting flanges, and are inserted into the pipe port end surface of the elastic hose; and at least two arc-shaped bulge loops are formed on the outer the peripheral wall and the inner peripheral wall of each connecting part respectively. When the deformation of a pipeline occurs, which is caused by thermal expansion and contraction, the elastic hose can generate transversal, axial and angular displacement, without the limitation of non-concentric pipelines and un-parallel flanges, so that a sealing effect at the pipe joint is improved, and the problem that the pipe joint has high probability of water leakage and water seepage is effectively solved.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of expansion joint pipe.
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 is to overcome deficiency of the prior art, and a kind of collapsible joint pipe is provided, and is intended to solve in the prior art pipe coupling position because of the internal stress effect of expanding with heat and contract with cold, and causes the easily infiltration problem of leaking of pipe coupling place.
The purpose of this utility model is achieved in that the expansion joint pipe, comprise the elastic hose that two ends link to each other with pipe coupling respectively, be connected with adpting flange on the two-port of described elastic hose respectively, the inboard working surface of described adpting flange is provided with the circular connector that is wholely set with described adpting flange, and described circular connector embeds in the mouth of pipe end face of described elastic hose; The periphery wall of described circular connector and inner circle wall are respectively equipped with twice arc bulge loop at least.
Compared with prior art, the beneficial effects of the utility model are: elastic hose is connected with pipe coupling by the adpting flange at two ends, when pipeline deforms because expanding with heat and contract with cold, elastic hose can produce laterally, axial, angular displacement, be not subjected to pipeline decentraction, the uneven restriction of flange, improve the sealing effect of pipe coupling place, effectively solved the problem that pipe coupling place is easily seeped water and leaked; The arc bulge loop can prevent that elastic hose and adpting flange from getting loose, and makes both connections more firm, and medium leaks from the flexible pipe port in also can preventing from managing, and plays seal action.
As further improvement of the utility model, the periphery wall of described elastic hose is provided with the braiding net, fixedlys connected with described adpting flange by fastening flange respectively in the two ends of described braiding net.The setting problem of avoiding the elastic hose overexpansion to cause elastic hose to break of braiding net has strengthened the mechanical strength of adaptor tube.
As further improvement of the utility model, also be embedded with the spiral wire rope in the described elastic hose.When the joint of pipe coupling was positioned at bending part, the spiral wire rope was played a supporting role to elastic hose, had solved elastic hose because bending distortion bore diminishes, the problem that medium can't circulate in causing managing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 elastic hose; 2 adpting flanges; 201 circular connectors; 3 braiding nets; 4 fastening flanges; 5 spiral wire ropes.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, comprise the elastic hose 1 that two ends link to each other with pipe coupling respectively, be connected with adpting flange 2 on the two-port of elastic hose 1 respectively, the inboard working surface of adpting flange 2 is provided with the circular connector 201 that is wholely set with adpting flange 2, and circular connector 201 embeds in the mouth of pipe end face of elastic hose 1; The periphery wall of circular connector 201 and inner circle wall are respectively equipped with twice arc bulge loop at least.The periphery wall of elastic hose 1 is provided with braiding net 3, fixedlys connected with adpting flange 2 by fastening flange 4 respectively in the two ends of braiding net 3.Also be embedded with spiral wire rope 5 in the elastic hose 1.
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.
Claims (3)
1. expansion joint pipe, it is characterized in that, comprise the elastic hose that two ends link to each other with pipe coupling respectively, be connected with adpting flange on the two-port of described elastic hose respectively, the inboard working surface of described adpting flange is provided with the circular connector that is wholely set with described adpting flange, and described circular connector embeds in the mouth of pipe end face of described elastic hose; The periphery wall of described circular connector and inner circle wall are respectively equipped with twice arc bulge loop at least.
