Abstract
The invention relates to a pipeline connecting device comprising a pipeline butt-joint connecting member, wherein the pipeline abut-joint connecting member comprises a connecting part and a regulating part, the regulating part comprises an inner groove which is annular or spiral in a connecting state, and the connecting part comprises a connecting section which extends and is sleeved along the axial direction of a connected pipeline from two sides of the inner groove and hermetically adhered to or wound and adhered to the outer circumference of the abut-joint end of the connected pipeline in a connecting state. In the invention, because the pipeline butt-joint connecting member with the inner groove is adopted, the coaxiality of two sections of abutt-joint pipelines can be better ensured when the length of the pipeline deforms due to the change of environmental temperature so as to meet the connecting requirements of the coaxiality height of the pipeline; since the depth of the inner groove does not exceed the cylindrical surface of the inner side surface of the pipeline, the flowing of a medium in the pipeline is not hindered, the smoothness of the inner wall of the pipeline is improved, and the medium flowing and the operation of a pipeline robot in a pipe network are facilitated.
Description
Technical field
The present invention relates to the connection set of a kind of connecting tube butt end.
Background technique
Pipeline butt end connector is the vitals in the pipe network structure, is related to reliability, efficiency of construction and pipeline network construction cost that pipe network connects sealing.
Because seasonal variations, cause the Environmental Conditions temperature variation of pipe network very big, the limit temperature difference in most Area during Summer and winter usually between 40 degrees centigrade to 60 degrees centigrade, the cold area limit temperature difference in addition up to 70 degrees centigrade to 80 degrees centigrade.The existence of the limit temperature difference makes the pipe network of long distance produce the bigger pipeline amount of deformation that expands with heat and contract with cold, and has a strong impact on the connection reliability of pipeline butt end connector.Because pipeline butt end connector and pipeline butt end are close-connected; When pipeline produces length deformation because of temperature variation, bigger variation will take place in the expansion joint distance of pipeline butt end, often make pipeline butt end connector produce gross distortion; Cause seal failure and pipe leakage; When serious even make pipe end withstand evagination mutually, or tear pipeline butt end connector construction, cause pipeline butt end connector to damage because of distance widens.
Connect the defective that lost efficacy and damaged in order to overcome existing pipeline butt end connector because of variation of ambient temperature causes pipeline butt end connector, compensating type pipeline butt end connector occurred.As shown in Figure 1; The patent No. is that the Chinese patent of 200920161641.X discloses a kind of " linkage structure with steel plastic composite structure wall pipe of vertical reinforcing rib "; This linkage structure is the plastic socket pipe fitting 2 that has Ω shape section configuration; Plastic pipe 1 butt end is inserted at the two ends of this plastic socket pipe fitting 2 respectively; And adopting molten plastic 3 to be fixedly connected plastic pipes 1 and plastic socket pipe fittings 2, the Ω shape section through outside protrusion absorbs the duct length distortion that pipe network produces because of variation of ambient temperature.
There is following defective in the pipeline butt end linkage structure of the above-mentioned Ω of having shape section configuration:
1, because the Ω shape section of this linkage structure adopts the structure of protrusion outside tube wall, the maximum outside diameter size of Ω shape section is big, keeps the coaxial ability of connected two segment pipes relatively poor; When the pipe network length deformation takes place; The axis of connected two segment pipes can squint, when serious even make the structure generation shear fracture of pipeline butt end connector, therefore; Connect the pipeline connection that coaxality is had relatively high expectations for pipeline, be difficult to meet the demands;
2, this linkage structure adopts bayonet joint; The insertion end of connection set forms a ring-shaped step in tube wall; Can influence the smooth and easy runner of medium in the pipe on the one hand, produce media accumulation, on the other hand; When adopting pipeline robot that pipeline is overhauled, can hinder the current of pipeline robot, even in pipe, can't use pipeline robot.
Summary of the invention
The technical problem that the present invention will solve is, a kind of assembling pipe joint is provided, and overcomes the coaxial ability of existing technology connecting tube, the irregular defective of connecting tube inwall.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of assembling pipe joint; Comprise pipeline butt joint link; It is characterized in that; This pipeline butt joint link comprises joint and adjustment part; Said adjustment part is included in coupled condition ringwise or spiral inner groovy, said joint be included in coupled condition by said inner groovy both sides along connected pipe extend axially suit and sealing attached to or twine and sealing attached to the linkage section on the excircle of connected pipe butt end.
In assembling pipe joint of the present invention, said linkage section comprises adhesive layer with the inner surface that connected pipe butt end excircle cooperates.
In assembling pipe joint of the present invention, at the inner surface of the said inner groovy of coupled condition between connected pipe inwall cylndrical surface and excircle cylndrical surface, connected pipe butt end.
In assembling pipe joint of the present invention, said inner groovy is one, two, three or four.
In assembling pipe joint of the present invention, comprise external fastening, this external fastening coupled condition suit and fastening encirclement or twine and the fastening external cylindrical surface that is enclosed in said pipeline butt joint link on.
In assembling pipe joint of the present invention, said external fastening is the molten cover of shrink belt, heat-contraction sleeve, Electric thermal smelting belt or electric heating.
In assembling pipe joint of the present invention; Said external fastening is outside fastening cutting ferrule or outside restraint zone; This fastening cutting ferrule, this restraint zone comprise fastening piece inner fovea part, adpting flange and connecting bolt respectively; This fastening piece inner fovea part cooperates with the inner groovy of said pipeline butt joint link, and this connecting bolt passes said adpting flange said fastening cutting ferrule or outside restraint zone are fastenedly connected on the external cylindrical surface of said pipeline butt joint link.
In assembling pipe joint of the present invention; Comprise filling tape; This filling tape is filled in the outer surface circular groove or the interior fill area that forms at least one circumference of spiral slot of connected pipe butt end continuously; Under assembling condition, the external peripheral surface of this filling tape is close to the inner surface that said pipeline docks link.
The assembling pipe joint of embodiment of the present invention compares with existing technology, and its beneficial effect is:
1. adopt the pipeline butt joint link of band inner groovy, when pipeline produced length deformation because of variation of ambient temperature, the coaxality that can guarantee to dock two segment pipes better satisfied the high connection request of pipeline coaxality;
2. the degree of depth of inner groovy does not exceed the cylndrical surface on insides of pipes surface, and can not flow to pipeline internal medium forms obstacle, improves the planarization of inner-walls of duct, is beneficial to media flow and the operation of pipeline robot in pipe network in the pipe.
