Abstract
The invention discloses a pipe sleeve for heat-shrinkable pipe connection based on a conical casing pipe to solve the problem that in the prior art, the structure of a connecting pipe sleeve cannot well adapt to installing and sealing of a heat-shrinkable pipe. The pipe sleeve comprises a casing pipe body with a base part and a connecting part and is characterized in that the connecting part is further internally provided with a casing pipe with the axial direction identical with that of the connecting part; the casing pipe is conical, the outer diameter of the side, close to the base part, of the casing pipe is d, and the outer diameter of the side, away from the base part, of the casing pipe is 1, wherein d is larger than 1; and the side, adjacent to the base part, of the casing pipe and the side, adjacent to the base part, of the connecting part are integrally connected, and a heat seal layer is arranged on the outer side wall of the casing pipe. According to the pipe sleeve, the casing pipe is arranged in the connecting part and is provided with the heat seal layer, after heating is conducted, an integral structure can be formed by the heat seal layer on the casing pipe and a heat seal layer on the heat-shrinkable pipe, a better bonding effect is effectively achieved, the phenomenon that the joint of pipelines is exposed out is avoided, and the sealing effect is effectively improved.
Description
Technical field
The present invention relates to and a kind of connect pipe box, what be specifically related to is heat-shrinkable T bush connecting pipe cover based on taper.
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 heat-shrinkable T bush connecting pipe cover based on taper of easy and simple to handle, Be very effective.
For achieving the above object, technological scheme of the present invention is as follows:
Based on the heat-shrinkable T bush connecting pipe cover of taper, 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 pipe is taper, if the external diameter of this sleeve pipe adjacent base side is d, external diameter away from base portion side is l, then d is greater than l; And sleeve pipe and joint adjacent base side connect as one, described outside of sleeve wall is 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.
Preferred as one, described this sleeve outer l 4-6mm less of joint internal diameter.
In order to prevent heat-shrinkable T bush from deviating from the present invention, 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 present invention compared with prior art, has the following advantages and beneficial effect:
1, pass through when the present invention uses to inject hot melt adhesive 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;
2, the setting of projecting teeth 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.
