Description
Technical field
The utility model relates to municipal works plastic drainage pipeline interconnection technique field, especially a kind of piece-shape type heat is received
Contracting set.
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 insulation,
The performances such as heatproof.It has softness flexible, is widely used in various harness, solder joint, the insulation protection of inductance, metal tube, stick
Antirust, corrosion protection etc..In municipal works plastic drainage pipeline, in order to guarantee that seal for pipe joints is reliable, in plastic drain-pipe
Outer packaging components are arranged in road joint, as number of patent application is " 201710290882.3 ", entitled " a kind of polyethylene plastic steel twines
Around drainpipe composite joint construction technology ", but its structure is complex, installation period is longer.In addition, applicant has been presented for
Application No. is " 200920081660.1 ", the Chinese utility model patents and application number of entitled " tubular thermal shrinkable sleeve pipe "
For " 201420328254.1 ", the Chinese utility model patent of entitled " heat-shrinkable T bush "；But there is also following for above-mentioned technology
Shortcoming:
First, the structure of tubular thermal shrinkable sleeve pipe and heat-shrinkable T bush is complex, and manufacturing process is relatively complicated, so just
Increase production cost；
Second, the joint of tubular thermal shrinkable sleeve pipe and heat-shrinkable T bush is all made of upper and lower level arrangement (tubular thermal shrinkable sleeve pipe
Three-decker, heat-shrinkable T bush double-layer structure), be designed in this way bring and be disadvantageous in that: during pyrocondensation, joint it is interior
Layer is heated even (i.e. there are heat-conduction effects for the ectonexine of joint) with the uneven heating of non-joint, and the outer layer of joint is heated
Installation requirement is had reached, but the temperature of internal layer is lower than installation requirement；In turn, cause heated syncretizing effect poor.
Third, tubular thermal shrinkable sleeve pipe and heat-shrinkable T bush, which need to roll repeatedly, could allow joint docile；It is upper and lower level
Splice existing certain deficiencies.
Therefore, it is badly in need of proposing a kind of simple structure, simple installation, the piece-shape type heat shrinking sleeve for reducing production cost.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of piece-shape type heat shrinking sleeve, the utility model is adopted
Technical solution is as follows:
A kind of piece-shape type heat shrinking sleeve, the pyrocondensation substrate including piece-shape type, be arranged in the both ends of pyrocondensation substrate and with it is described
Integrally formed first end head of pyrocondensation substrate and the second end head, and opened up respectively along the radial direction of pyrocondensation web substrate collection
In first end head and the second end head and correspond a matched at least column sewing hole；First end head
Opposite be bonded is used with the second end head；The first end head and the of pyrocondensation substrate is fixed in setting for roll up collection in the sewing hole
The high temperature suture of two end heads.
Further, the piece-shape type heat shrinking sleeve further includes the inside for being pressed together on the pyrocondensation substrate, for being pasted onto
Pipeline outer ledge and the composite layer flushed with the pyrocondensation substrate.
Preferably, the high temperature suture is by cotton, polyolefin, nylon, terylene, polyamide fibre, polyvinyl, aramid fiber, glass fibre
One of or several materials mixing after made of.
Preferably, the composite layer is hot melt adhesive.
Preferably, the length of first end head and the second end head is 5~50cm.
Compared with prior art, the utility model has the following beneficial effects:
The pyrocondensation substrate of the utility model is single layer structure, and internal layer hot melt adhesive is easier heated fusion, it is viscous to form sealing
It connects, overcomes defective mounting existing for double-deck and multilayered structure completely.During installation, joint is circumferentially contracted for the utility model, closes
Hot melt adhesive self-assembling formation at seam is without dead angle sealing structure.Moreover, the pyrocondensation substrate of the utility model is heated evenly, installation
There are folds at rear portion.In conclusion to have that structure is simple, simple installation, production cost is low, fitting is reliable etc. excellent for the utility model
Point has very high practical value and promotional value in municipal works plastic drainage pipeline interconnection technique field.
