Abstract
The utility model discloses a plastic outside protective polyurethane foam insulating tee joint which comprises a steel three-way pipe body, a polyurethane foam insulating layer and a plastic outside protective tee joint, wherein the steel three-way pipe body is positioned in a plastic outside protective three-way cavity; the polyurethane foam insulating layer is filled between the periphery of the steel three-way pipe body and the plastic outside protective tee joint; a main pipe and a branch pipe of the plastic outside protective tee joint are welded together; a plastic reinforced cape is also arranged on a weld joint in a riding and pressing manner; and a metal resistance wire mesh is arranged in a hot melting zone between an inner arc surface of the plastic reinforced cape and the main pipe and the branch pipe of the plastic outside protective tee joint. The plastic outside protective polyurethane foam insulating tee joint disclosed by the utility model is a pipeline connecting piece matched with a polyurethane foam plastic prefabricated directly-buried insulating pipe as a high-density polyethylene outside protective pipe; and the plastic outside protective tee joint is reinforced, so that the important action of prolonging the integral service life of a pipe network is achieved.
Description
Technical field:
The utility model relates to a kind of plastics and protects the polyurethane foam insulation threeway outward, is a kind of pipeline connecting parts that matches with " the outer pillar urethane foam prefabricated direct-buried thermal insulation pipe of high density polyethylene (HDPE) ", belongs to the heat distribution pipeline technical field.
Technical background:
At present, in the urban heating pipe network, the insulation threeway generally all is according to CJ/T155-2001 " the outer pillar urethane foam prefabricated direct-buried thermal insulation pipe spare of high density polyethylene (HDPE) " standard production, the attachment weld that plastics protect the threeway person in charge and arm outward only is to adopt plastics to extrude welding, and the tee pipe fitting stress deformation is very big, and cracking appears in the as easy as rolling off a log attachment weld that causes plastics to protect the threeway person in charge and arm outward.
Summary of the invention:
The purpose of this utility model is to provide a kind of plastics to protect the polyurethane foam insulation threeway outward, the person in charge by protecting threeway outside plastics and the arm weld joint that crosses is laid plastics and is strengthened tippet, improve the person in charge and arm join strength that plastics protect threeway outward, can effectively avoid weld cracking.
Implementation:
Design a kind of plastics and protect the polyurethane foam insulation threeway outward, comprise the Steel triplet body, polyurethane foam insulation layer, plastics protect threeway outward and form, it is characterized in that: the Steel triplet body is positioned at plastics and protects three cavities outward, Steel triplet body periphery and plastics protect filled polyurethane foam heat-insulation layer between the threeway outward, plastics protect the person in charge and the arm welding of threeway outward, ride the weld seam that crosses of pressing plastics to protect the person in charge of threeway and arm outward and also be provided with plastics and strengthen tippet, described plastics are strengthened tippet intrados and plastics and are protected outward in the person in charge of threeway and the arm hot melt district metal electric heating silk screen is arranged.
It is saddle plastic tab and the concave arc surface embedded with metal heating wire net of a pre-molding that described plastics are strengthened tippet, and plastics are strengthened person in charge's fusion face diameter that tippet and plastics protect threeway outward than more than the big 50mm of arm diameter, with the fusion height of arm greater than 50mm.
The material that described plastics are strengthened tippet is identical with the material of three-way plastic tube.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural profile schematic representation
Fig. 2 is profile
Among the figure: the 1st, Steel triplet; The 2nd, polyurethane foam insulation layer; The 3rd, plastics protect the person in charge of threeway outward; The 4th, plastics protect the arm of threeway outward; The 5th, plastics protect the person in charge of threeway and the arm weld seam that crosses outward; The 6th, plastics are strengthened tippet; The 7th, the heating wire net.
Embodiment
Specification according to Steel triplet pipe 1, be responsible for 3 at plastic three-way and open a hole corresponding with plastics arm 4 sizes, the Steel triplet body is inserted in plastic three-way to be responsible in 3 and the arm of Steel triplet is protruded out, to be responsible for 3 with arm 4 align welding, adjust Steel triplet body and three-way plastic tube relative position, the plastics of pre-molding are in advance strengthened tippet 6 be inserted in arm 4, plastics are strengthened tippet 6 concave arc surfaces towards being responsible for 3, with mould plastics tippet 6 and the person in charge 3 are compressed, the electricity consumption hot-melt welding machine gives the metal electric heating silk screen 7 logical heating, until the concave arc surface of plastics tippet 6 and plastic three-way is responsible for and arm fuses into one, the relative position of adjusting plastic three-way and Steel triplet 1 again is also fixing, outside Steel triplet body periphery and plastics, protect injection polyurethane 2 between the threeway, finally form plastics described in the utility model and protect the polyurethane foam insulation threeway outward.
Plastics described in the utility model protect the polyurethane foam insulation threeway outward, strengthen because plastics are protected threeway outward, have important function to improving the pipe network whole service life.
Claims (3)
1. plastics protect the polyurethane foam insulation threeway outward, comprise the Steel triplet body, polyurethane foam insulation layer, plastics protect threeway outward and form, it is characterized in that: the Steel triplet body is positioned at plastics and protects three cavities outward, Steel triplet body periphery and plastics protect filled polyurethane foam heat-insulation layer between the threeway outward, plastics protect the person in charge and the arm welding of threeway outward, ride the weld seam that crosses of pressing plastics to protect the person in charge of threeway and arm outward and also be provided with plastics and strengthen tippet, described plastics are strengthened tippet intrados and plastics and are protected outward in the person in charge of threeway and the arm hot melt district metal electric heating silk screen is arranged.
2. protect the polyurethane foam insulation threeway outward according to the described plastics of claim 1, be further characterized in that: it is saddle plastic tab and the concave arc surface embedded with metal heating wire net of a pre-molding that described plastics are strengthened tippet, plastics are strengthened person in charge's fusion face diameter that tippet and plastics protect threeway outward than more than the big 50mm of arm diameter, with the fusion height of arm greater than 50mm.
3. protect the polyurethane foam insulation threeway outward according to the described plastics of claim 1, the material that its described plastics are strengthened tippet is identical with the material of three-way plastic tube.
