The utility model discloses a sleeve pipe body that has basal portion and connecting portion, its characterized in that: connecting portion inside still is provided with the sleeve pipe that the axial is unanimous with connecting portion, and this sleeve pipe is the toper, and the external diameter of establishing the neighbouring basal portion one side of this sleeve pipe is d, and the external diameter of keeping away from basal portion one side is l, and then d is greater than l, and the sleeve pipe is connected as an organic wholely on one side of the neighbouring basal portion of connecting portion, the sleeve pipe lateral wall is provided with one deck heat seal layer. The utility model discloses a set up the sleeve pipe in connecting portion, set up the heat seal layer on the sleeve pipe, the heating back, a heat seal layer and the laminiform one -tenth of the heat seal on a heat shrinkage bush body structure on the accessible sleeve pipe effectively reach adhesive effect better, and then avoid the naked circumstances of pipe connection department to take place, effectively improve sealed effect.
Description
Technical field
The utility model relates to a kind of connection pipe box, and what be specifically related to is that falling-proof type heat-shrinkable T bush connects pipe box.
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 problem that the installation that the structure that the purpose of this utility model is to solve existing connection pipe box can not be applicable to heat-shrink tube well seals, provides a kind of falling-proof type heat-shrinkable T bush easy and simple to handle, Be very effective to connect pipe box.
For achieving the above object, the technical solution of the utility model is as follows:
Falling-proof type heat-shrinkable T bush connects pipe box, comprise the sleeve body with base portion and joint, described joint inside is also provided with the axis sleeve pipe consistent with joint, this sleeve outer wall is tapered, 1mm should be less than away from the outer diameter of base portion side and the difference of inner diameter, if the outer diameter of this sleeve pipe adjacent base side is d, the outer diameter away from base portion side is l, then d is greater than l; And the sleeve pipe of adjacent base side and joint connect as one, described outside of sleeve wall is also provided with one deck 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, after heating, the thermal synthesis layer that thermal synthesis layer on hot melt adhesive and heat-shrinkable T bush and outside of sleeve wall are arranged forms integrative-structure, effectively reach the situation avoiding pipeline junction exposed to occur, and then effectively improve the effect of sealing.
By the inwall of sleeve pipe be cylindrical body, outer wall is the setting of cone structure, effectively avoid there is larger gap between the heat-shrinkable T bush of the utility model and position and pipeline, and then affect sealing effect, increase the working life of heat-shrinkable T bush and the utility model joint pipeline.
Preferred as one, described this sleeve outer wall diameter l 4-6mm less of joint inner diameter, the outer diameter d of sleeve pipe equals joint inner diameter.
In order to prevent heat-shrinkable T bush from deviating from the utility model, making sealing effect better, described outside of sleeve wall is also provided with projecting teeth.
In order to reach effect better, described sleeve pipe and joint are formed in one structure.
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, the utility model passes through the setting that the inwall of sleeve pipe is cylindrical body, outer wall is cone structure, effectively avoid there is larger gap between the heat-shrinkable T bush of the utility model and position and pipeline, and then affect sealing effect, increase the working life of heat-shrinkable T bush and the utility model joint pipeline.
2, by injecting hot melt adhesive between sleeve pipe and joint when the utility model uses, after heating, the thermal synthesis layer that thermal synthesis layer on hot melt adhesive and heat-shrinkable T bush and outside of sleeve wall are arranged forms integrative-structure, effectively reach the situation avoiding pipeline junction exposed to occur, and then effectively improve the effect of sealing;
3, the setting of projecting teeth 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;
4, simple, the Be very effective of the utility model structure, is applicable to applying very much.
