Abstract
The utility model discloses a connecting piece of firm type heat shrinkage bush bonds has solved the sealed problem of installation that the structure of connecting the pipe box among the prior art can not not be applicable to the pyrocondensation pipe well. The utility model discloses a sleeve pipe body that has basal portion (1) and connecting portion (2), its characterized in that: connecting portion (2) inside still to be provided with sleeve pipe (3) that the axial is unanimous with connecting portion (2), and sleeve pipe (3) that should neighbouring basal portion (1) one side are as an organic whole admittedly through connecting piece (4) and connecting portion (2), sleeve pipe (3) are cylindrical, still are provided with on this sleeve pipe (3) outer wall heat seal layer (5). The utility model discloses a set up the sleeve pipe in connecting portion, and then can pour into the hot melt adhesive into between sleeve pipe and connecting portion, through the heat seal layer on hot melt adhesive and the sleeve pipe outer wall to and form a body structure after the heating of the heat seal layer on the heat shrinkage bush, effectively reach and avoid the naked circumstances of pipe connection department to take place, and then effectively improve sealed effect.
Description
Technical field
The utility model relates to and a kind of connects pipe box, and what be specifically related to is the link of bonding firm type heat-shrinkable T bush.
Background technique
Heat-shrinkable T bush is a kind of special polyolefin material thermal contraction casing tube, also has and is called EVA material, have the performances such as insulation, heatproof.It has soft flexible, is widely used in the insulation protection of various wire harness, solder joint, inductance, antirust, the corrosion protection of metal tube, rod.As the sealing for pipeline junctions such as petroleum pipeline, natural gas line and drainage pipes, anti-fluid is revealed from pipeline junction, causes the pollution to surrounding environment.Be used in wire terminal, can make it to tighten by heating, play insulation, the functions such as protection.Heat-shrinkable T bush is a kind of heat-shrinkage material; namely heat shrinks, and divides pvc heat-shrinkable T bush, pet heat-shrinkable T bush, IXPE heat-shrinkable T bush, 10KV high-voltage busbar can be divided into protect heat-shrinkable T bush, 35KV high-voltage busbar protection heat-shrinkable T bush, containing glue double wall heat Heat-Shrinkable Tubings and imitative wood grain heat-shrinkable T bush by material.
Heat-shrinkable T bush is overlapped by material contracting with heat to form, and material contracting with heat exists three-decker usually, two-layer material contracting with heat layer and one deck thermal synthesis layer.Easily shrink because material contracting with heat is heated when 2-4mm is thick, can tightly be attached on pipeline, thus in the using process of reality, after only heat-shrinkable T bush need being socketed in pipeline junction heating make heat-shrinkable T bush shrink tightly be attached on pipeline; Simultaneously, due to the characteristic of easily shrinking of being heated, in pipe fitting joint, shrink not in place when the structure of existing connection pipe box can cause the heat-shrink tube at this place to heat, make pipe fitting joint poorly sealed, pipeline is easy to corrode herein, and the fluid in pipeline is also easily revealed from here, causes the pollution of surrounding environment.
Model utility content
The structure that the purpose of this utility model is to solve existing connection pipe box can not be applicable to the problem of the installation sealing of heat-shrink tube well, provides a kind of link of bonding firm type heat-shrinkable T bush of easy and simple to handle, Be very effective.
For achieving the above object, the technical solution of the utility model is as follows:
The link of bonding firm type heat-shrinkable T bush, comprises the sleeve body with base portion and joint, and described joint inside is also provided with the axis sleeve pipe consistent with joint, and the sleeve pipe of this adjacent base side is solidified as a whole by link and joint; Described sleeve pipe is cylindrical, and this sleeve outer wall is also provided with thermal synthesis layer.
First between sleeve pipe and joint, inject hot melt adhesive, then heat-shrinkable T bush is placed between sleeve pipe and joint, by the thermal synthesis layer in hot melt adhesive and sleeve outer wall, and on heat-shrinkable T bush thermal synthesis layer heating after form integrative-structure, effectively reach the situation avoiding pipeline junction exposed to occur, and then effectively improve the effect of sealing.
Limiting tooth is provided with on described sleeve outer wall and on joint inwall; This limiting tooth is positioned at adjacent base one end.
Sleeve pipe, by the setting of limiting tooth, is effectively avoided heat-shrinkable T bush to heat aftershrinkage and then is caused heat-shrinkable T bush to deviate from situation of the present utility model occurring, improve sealing effect.
Further, described sleeve pipe is cylindrical, and this limiting tooth is positioned at adjacent base one end.
In order to reach effect better, this sleeve outer wall diameter described 4-6mm less of joint inner diameter.
Preferred as one, described base portion is swan neck, straight tube, three-way pipe, four-way pipe or reducer.
Preferred as another kind, the material of described base portion and joint is pyrocondensation material.
The utility model compared with prior art, has the following advantages and beneficial effect:
1, by the thermal synthesis layer in hot melt adhesive and sleeve outer wall when the utility model uses, and form integrative-structure after thermal synthesis layer heating on heat-shrinkable T bush, effectively reach the situation avoiding pipeline junction exposed and occur, and then effectively improve the effect sealed;
2, the setting of limiting tooth in the utility model, effectively avoids heat-shrinkable T bush to heat aftershrinkage and then causes heat-shrinkable T bush to deviate from situation of the present utility model occurring, improve sealing effect;
3, simple, the Be very effective of the utility model structure, is applicable to applying very much.
