Abstract
The utility model discloses a based on heat shrinkage bush with connecting pipe box 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 this sleeve pipe (3) external diameter is than the little 4 -6mm of connecting portion (2) internal diameter, and sleeve pipe (3) are connected as an organic wholely with connecting portion (2) vicinity basal portions (1) one sides. The utility model discloses a set up the sleeve pipe in connecting portion, and then can inject the hot melt adhesive into between sleeve pipe and connecting portion, form a body structure after heating through hot melt adhesive and 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 effective effect of sealing up that improves.
Description
Technical field
The utility model relates to a kind of connection pipe box, and what be specifically related to is with connecting pipe box based on 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, provide a kind of easy and simple to handle, Be very effective based on heat-shrinkable T bush with connecting pipe box.
For achieving the above object, the technical solution of the utility model is as follows:
Based on heat-shrinkable T bush with connecting 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 4-6mm less of joint internal diameter, and sleeve pipe and joint adjacent base side connect as one.
First between sleeve pipe and joint, inject hot melt adhesive, then heat-shrinkable T bush is placed between sleeve pipe and joint, form integrative-structure after being heated by the thermal synthesis layer in hot melt adhesive and heat-shrinkable T bush, effectively reach the situation avoiding pipeline junction exposed and occur, and then effectively improve the effect of sealing.
Further, described sleeve pipe is taper, if the diameter of this sleeve pipe adjacent base side is d, the diameter away from base portion side is l, then d is less than or equal to l.
Sleeve pipe, by the setting of this taper, 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.
In order to reach effect better, described sleeve pipe to be fixed as one structure by link and joint.
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 injecting hot melt adhesive between sleeve pipe and joint when the utility model uses, integrative-structure is formed after being heated by the thermal synthesis layer in hot melt adhesive and heat-shrinkable T bush, effectively reach the situation avoiding pipeline junction exposed to occur, and then effectively improve the effect of sealing;
2, the setting of the utility model middle sleeve taper, 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
