Description
Technical field
The utility model relates to heating direct-buried insulating tube pipe joint heat preservation method more particularly to a kind of heat supply pipeline connectors
Heat preservation support portal structure.
Background technique
When heating direct-buried utilidor is installed, it is close that the connector heat preservation between pipeline generally does outer shield welding using electric heating melting set
It seals, then foamed heat insulating.Electric heating melting set is that plate is coated on outside pipeline outer protection tube, both ends circumferential weld electric heating fusion welding, and centre is vertical
It is also electric heating fusion welding to lap weld, intermediate longitudinal joint is since inside is cavity, without any support.When electric heating melting, which covers, to be heated,
Electric heating melting set softening, collapses into cavity, so that the welding of longitudinal joint is not can guarantee quality, longitudinal joint is caused to leak.
Utility model content
The purpose of the utility model is to provide a kind of heat supply pipeline connectors to keep the temperature with support portal structure, the support gantry knot
Structure may insure that electric heating melting covers not generate in electric heating fusion welding process and collapse, and guarantee that electric heating melting covers weldquality, it is ensured that heat supply
Pipe joint heat insulation effect.
To achieve the above object, the utility model is implemented with the following technical solutions:
A kind of heat supply pipeline connector heat preservation support portal structure, the instrumentation tubes being welded to connect including two, weld seam two sides
Instrumentation tubes on be enclosed with polyurethane insulation coating and outer protection tube respectively, further include electric heating melting set, support gantry, the electric heating melting set
It is wrapped in commissure, the both ends of electric heating melting set and the outer protection tube of weld seam two sides overlap, and the electric heating melting set forms longitudinal lap joint weldering
Seam, the support gantry are supported in the inside of the longitudinal seam of electric heating melting set.
The support gantry includes gantry plate, stiffening plate, flat chisel shape elongated end, and two stiffening plates are arranged in the two of gantry plate
Side constitutes U-shaped structure, and the both ends of gantry plate are outward extended with flat chisel shape elongated end, and the flat chisel shape at the support gantry both ends is prolonged
It stretches to hold in the polyurethane insulation coating for being plugged on instrumentation tubes weld seam two sides and fixes support gantry.
The support gantry is plastic part.
Compared with prior art, the beneficial effects of the utility model are:
A kind of heat supply pipeline connector heat preservation support portal structure, the support portal structure may insure that electric heating melting is covered in electricity
It does not generate and collapses during sweat soldering, guarantee that electric heating melting covers weldquality, it is ensured that heat supply pipeline connector heat insulation effect.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of heat supply pipeline connector heat preservation support portal structure of the utility model；
Fig. 2 is the structural schematic diagram for supporting gantry.
In figure: 1. electric heating melting sets, 2. polyurethane insulation coatings, 3. support gantries, 4. instrumentation tubes, 5. outer protection tubes, 6. flat chisel shapes
Elongated end, 7. gantry plates, 8. stiffening plates.
Specific embodiment
The embodiments of the present invention is further illustrated combined with specific embodiments below:
As Figure 1-Figure 2, a kind of heat supply pipeline connector heat preservation is with support portal structure, the work being welded to connect including two
Make pipe 4, be enclosed with polyurethane insulation coating 2 and outer protection tube 5 respectively in the instrumentation tubes 4 of weld seam two sides, further includes electric heating melting set 1, branch
Gantry 3 is supportted, the electric heating melting set 1 is wrapped in commissure, and the both ends of electric heating melting set 1 and the outer protection tube 5 of weld seam two sides overlap, described
Electric heating melting set 1 forms longitudinal lap joint weld seam, and the support gantry 3 is supported in the inside of the longitudinal seam of electric heating melting set 1.
The support gantry 3 includes gantry plate 7, stiffening plate 8, flat chisel shape elongated end 6, and two stiffening plates 8 are arranged in gantry
The two sides of plate 7 constitute U-shaped structure, and the both ends of gantry plate 7 are outward extended with flat chisel shape elongated end 6,3 both ends of support gantry
Flat chisel shape elongated end 6 be plugged in the polyurethane insulation coating 2 of instrumentation tubes weld seam two sides will support gantry 3 it is fixed.
The support gantry 3 is plastic part.
The heat supply pipeline connector heat preservation of the utility model is to solve electric heating melting set 1 in sweat soldering with support portal structure
Inwardly the problem of collapsing and design.(partial cutaway view that Fig. 1 is electric heating melting set 1) as shown in Figure 1, two instrumentation tubes 4 are logical
Welded connecting is crossed, since welding operates, has a distance not have protective polyurethane layer 2 and outer shield in the two sides of 4 weld seam of instrumentation tubes
Pipe 5, the commissure need separately to make isothermal holding, the package electric heating melting set 1 in the commissure.Electric heating melting set 1 is plate, is wrapped up
In the outer protection tube 5 of 4 weld seam two sides of instrumentation tubes, electric heating melting set 1 has part overlap joint with outer protection tube 5, overlaps the fusion welding of circumferential weld electric heating.
Before package electric heating melting set 1, setting support gantry 3 at 1 longitudinal seam is covered in preset electric heating melting, 3 both ends of gantry will be supported
Flat chisel shape elongated end 6 be plugged in the polyurethane insulation coating 2 of instrumentation tubes weld seam two sides it is fixed.After wrapping up electric heating melting set 1, welding
Circumferential weld and longitudinal lap joint weld seam are overlapped, the longitudinal lap joint weld seam of electric heating melting set 1 has support gantry 3 to do in the position of support gantry 3
The integrated support of lap-joint, it is ensured that collapse phenomenon does not occur in lap-joint, guarantees welding quality.
