The utility model discloses a setting of opening cell body, inboard and outside shrink nonconformity that the pyrocondensation substrate heating of avoiding the tubulose body time results in, and then result in the junction to seal up the not tight circumstances to influence the installation accuracy, cause the junction and seal the not tight condition, effectively reach have when guaranteeing performance easy to assemble, improve advantage such as installation accuracy.
Description
Technical field
The utility model relates to a kind of heat-shrinkable T bush, and what be specifically related to is alternating expression opening slot 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 makes heat-shrinkable T bush shrink being attached on pipeline tightly.But, because heat-shrinkable T bush is heated the characteristic of easily shrinking, contraction due to outside heat-shrinkable T bush and inner side during heating is inconsistent, when making operation, easily there is error, and then the situation causing joint poorly sealed, pipeline is easy to corrode herein, fluid in pipeline is also easily revealed from here, causes the pollution of surrounding environment.
Model utility content
When the purpose of this utility model is to solve heating outside existing heat-shrinkable T bush and the contraction of inner side inconsistent, and then the situation causing joint poorly sealed, provides a kind of alternating expression opening slot 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:
Alternating expression opening slot heat-shrinkable T bush, comprises the tubular body being rolled into circular tube shaped by pyrocondensation base material, and tubular body two ends are provided with the lap segment that width is 2 ~ 30mm, and lap segment is fixed together by stitching thread; The outer side wall of described tubular body is staggeredly equipped with opening cell body along axial direction, and the degree of depth of described opening cell body is 1/3 ~ 1/2 of tubular body thickness, and the width of opening cell body is less than 1/20 of tubular body girth, and the length of opening cell body is 8 ~ 20cm.
By the setting of opening cell body, avoid the inner side and outer side caused during the pyrocondensation base material heating of tubular body to shrink inconsistent, and then affect installation precision, cause the situation that joint is poorly sealed.By above-mentioned setting, effectively reach while ensureing usability, convenient installation, improves installation precision.
As the setting of optimum, the opening cell body quantity that on the position, arbitrary place of described tubular body, one week is arranged is less than six.The opening cell body quantity that on tubular body, one week is arranged is limited to less than six, effectively avoids the Performance Strength of opening cell body to tubular body to impact, effectively ensure the working life of tubular body.
Further, described sutural wire diameter is 0.1 ~ 0.8mm, and sutural stitch distance is 1 ~ 10mm.
Further again, described stitching thread is selected from cotton, polyolefin, nylon, terylene, polyamide fibre, polyvinyl, aramid fiber.
Further, also thermal synthesis layer is provided with between described lap segment.
The utility model compared with prior art, has the following advantages and beneficial effect:
1, the utility model is by the setting of opening cell body, avoids the inner side and outer side caused during the pyrocondensation base material heating of tubular body to shrink inconsistent, and then affects installation precision, cause the situation that joint is poorly sealed.By above-mentioned setting, effectively reach while ensureing usability, convenient installation, improves installation precision;
2, the opening cell body quantity that on tubular body, one week is arranged is limited to less than six by the utility model, effectively avoids the Performance Strength of opening cell body to tubular body to impact, and effectively ensures the working life of tubular body;
3, simple, the Be very effective of the utility model structure, is applicable to applying very much.
