Preferably, the branch pipe outer protection tube material is high density polyethylene (HDPE).
Preferably, supervisor's outer protection tube is the electric heating melting set for being embedded with electric heating melting metal welding wire.
Preferably, the outer protection tube of being responsible for is the polyethylene sheets of no electric heating melting metal welding wire.
Compared with prior art, the utility model has the beneficial effects that combined type is used in heat supply pipeline field joint heat preservation When outer protection tube can make heat supply pipeline grafting three-way welding at the scene, effective thermal-insulating sealing is realized, can be improved heat supply supervisor Road with for hot leg pipe outside utilidor junction sealing performance.This heat supply pipeline field joint heat preservation combined type outer protection tube Supervisor's outer protection tube and branch pipe outer protection tube are welded in advance before installing with heat supply pipeline grafting threeway, and branch pipe Outer protection tube bottom surrounding is not contacted with the opening in supervisor's outer protection tube, then branch pipe outer protection tube bottom surrounding is enabled to protect with outside being responsible for Pipe welds together, and enabling the junction of branch pipe outer protection tube and supervisor's outer protection tube, there is no voids, guarantees branch pipe outer protection tube With the welded seal effect of the junction of supervisor's outer protection tube, and outer protection tube is responsible for equipped with isometric opening, so that protecting outside branch pipe Pipe and supervisor's outer protection tube will not interfere, then branch pipe outer protection tube will not interfere supervisor's outer protection tube to cover and be responsible for it in heat supply pipeline On.
Detailed description of the invention
Fig. 1 is a kind of heat supply pipeline field joint heat preservation combined type outer protection tube structural schematic diagram of the utility model;
Fig. 2 is that a kind of heat supply pipeline field joint heat preservation of the utility model uses combined type outer protection tube to use schematic diagram.
In figure: 1, branch pipe outer protection tube, 2, supervisor's outer protection tube.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of heat supply pipeline field joint heat preservation combination Formula outer protection tube, including supervisor's outer protection tube 2, supervisor's 2 top middle portion of outer protection tube are connected with branch pipe outer protection tube 1,1 material of branch pipe outer protection tube For high density polyethylene (HDPE), this structure makes the material of branch pipe outer protection tube 1 and general material is the former heating tube of high density polyethylene (HDPE) The material of road outer protection tube is identical, to guarantee the thermal insulation property of branch pipe outer protection tube 1, and the branch pipe outer protection tube 1 of same material and former heat supply Welding mean of the pipeline outer protection tube also convenient for users to keeping the temperature outer protection tube by the conventional connector such as shrink belt completes outer protection tube weldering Connect sealing, supervisor's outer protection tube 2 be the electric heating melting set for being embedded with electric heating melting metal welding wire, this structure makes 2 sets of supervisor's outer protection tube exist Heat supply is responsible for after outside, and the aperture position of supervisor's outer protection tube 2 can be soldered sealing by way of electric heating fusion welding, thus It enables heat supply pipeline grafting threeway junction by complete thermal-insulating sealing, is responsible for outer protection tube 2 as the polyethylene of no electric heating melting metal welding wire Sheet material, this structure make the material for being responsible for outer protection tube 2 and former heat supply pipeline outer protection tube same material, are responsible for the opening position of outer protection tube 2 It sets and two sides can complete supervisor's 2 opening of outer protection tube by the welding mean of the conventional connector heat preservation outer protection tube such as shrink belt With the welded seal of supervisor 2 two sides of outer protection tube and former heat supply pipeline outer protection tube, supervisor's 2 side wall of outer protection tube is interior to be equipped with opening, and opens Mouth length is equal to supervisor's 2 length of outer protection tube, and the opening and 1 bottom of branch pipe outer protection tube being responsible in outer protection tube 2 are non-intersecting, and outside supervisor 2 inner hole of pillar and 1 inner hole of branch pipe outer protection tube connect, and the axis for being responsible for outer protection tube 2 and branch pipe outer protection tube 1 is mutually perpendicular to, and main The junction of pipe outer protection tube 2 and branch pipe outer protection tube 1 is welded using grafting, and it is hot-melt polyethylene that welding bead, which is inside and outside two welding beads, Fillet weld is filled, this structure enables supervisor's outer protection tube 2 and branch pipe outer protection tube 1 before installing with heat supply pipeline grafting threeway It is welded in advance, and 1 bottom surrounding of branch pipe outer protection tube is not contacted with the opening in supervisor's outer protection tube 2, then enables and being protected outside branch pipe 1 bottom surrounding of pipe welds together with supervisor's outer protection tube 2, and branch pipe outer protection tube 1 is enabled not deposit with the junction for being responsible for outer protection tube 2 In void, guarantees branch pipe outer protection tube 1 and be responsible for the welded seal effect of the junction of outer protection tube 2, and be responsible for outer protection tube 2 Equipped with isometric opening, so that branch pipe outer protection tube 1 and supervisor's outer protection tube 2 will not interfere, then branch pipe outer protection tube 1 will not be interfered 2 sets of outer protection tube are responsible on heat supply pipeline supervisor.
Working principle: when using heat supply pipeline field joint heat preservation combined type outer protection tube, in steel pipe grafting After the completion of welding, the branch pipe outer protection tube 1 of prefabricated component is sleeved on steel branch pipe, is then outside the supervisor of sheet by reset condition Pillar 2 is buckled in the outer protection tube of supervisor two sides along heat supply supervisor's pipeline outer wall, conventional using electric heating fusion welding and shrink belt etc. The welding mean that connector keeps the temperature outer protection tube completes the welded seal that supervisor's outer protection tube 2 is open, because protecting outside supervisor's outer protection tube 2 and branch pipe The junction of pipe 1 uses grafting to weld in advance, and welding bead is inside and outside two welding beads, is hot-melt polyethylene filling fillet weld, therefore can The leakproofness of supervisor's outer protection tube 2 and 1 junction of branch pipe outer protection tube is effectively ensured, to complete a series of activities.
