Abstract

The invention discloses a firm connecting pipe sleeve based on a heat sealing layer. By adopting the firm connecting pipe sleeve based on the heat sealing layer, the problem that in the prior art, the structure of a connecting pipe sleeve cannot be well suitable for installation sealing of a heat shrink pipe is solved. The firm connecting pipe sleeve based on the heat sealing layer comprises a pipe sleeve body provided with a base part (1) and a connecting part (2) and is characterized in that the a sleeve (3) is further arranged in the connecting part (2), and the axial direction of the sleeve (3) is consistent with that of the connecting part (2); the part, close to one side of the base part (1), of the sleeve (3) and the connecting part (2) are fixed into a whole through a connecting part (4); the sleeve (3) is cylindrical; and the heat sealing layer (5) is further arranged on the outer wall of the sleeve (3). According to the firm connecting pipe sleeve based on the heat sealing layer, the sleeve is arranged in the connecting part, and hot melt adhesives are injected into the space between the sleeve and the connecting part; the hot melt adhesives, the heat sealing layer on the outer wall of the sleeve and a heat sealing layer on a heat shrink sleeve are heated to form an integrated structure, so the situation that the joints of pipelines are exposed is effectively avoided, and then the sealing effect is effectively improved.

Description

Firm type based on thermal synthesis layer connects pipe box
Technical field
The present invention relates to and a kind of connect pipe box, what be specifically related to is connect pipe box based on the firm type of thermal synthesis layer.
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.
Summary of the invention
The structure that the object of the invention 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 firm type based on thermal synthesis layer easy and simple to handle, Be very effective to connect pipe box.
For achieving the above object, technological scheme of the present invention is as follows:
Firm type based on thermal synthesis layer connects pipe box, 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 invention 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 present invention 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 present invention 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 of sealing;
2, the setting of limiting tooth in the present invention, effectively avoids heat-shrinkable T bush to heat aftershrinkage and then causes heat-shrinkable T bush to deviate from situation of the present invention occurring, improve sealing effect;
3, simple, the Be very effective of structure of the present invention, is applicable to applying very much.
