Abstract
An electric smelting sleeve connecting device for intermediate sections of an outer sheath of a preset buried heat-insulation pipe elbow relates to an elbow device of a preset buried heat-insulation pipe fitting. The electric smelting sleeve connecting device comprises a polyethylene electric smelting belt, connecting terminals and two PE (polyethylene) intermediate sections of the preset buried heat-insulation pipe elbow, the polyethylene electric smelting belt is connected with a PE intermediate section connecting gap between the two PE intermediate sections of the preset buried heat-insulation pipe elbow integrally, and the connecting terminals are respectively arranged on two sides of the polyethylene electric smelting belt. By the aid of the connecting device, a polyethylene outer sheath is not easy to crack after being stressed by external force so that the outer sheath has better effect, affection on heat insulation effect caused by damage of a heat-insulation layer due to crack of the welding joint of the outer sheath is avoided, and accordingly service life of the heat-insulation pipe fitting is prolonged greatly and operation and maintenance costs of a pipe network are reduced.
Description
Technical field:
The utility model relates to and presets direct-buried insulated pipe pipe elbow device, is specifically related to preset economize on electricity hot melt set of connection devices in the middle of the outer pillar of direct-buried insulated pipe elbow.
Background technique:
At present, preset segmentum intercalaris employing minute surface welding machine welding in the direct-buried insulated pipe pipe elbow.Two middle segmentum intercalaris are fixed on the minute surface welding machine, middle heating plate heating, two ends reach 200 degrees centigrade respectively, the termination fusing of segmentum intercalaris in the outer pillar of high density polyethylene (HDPE), machinery separates segmentum intercalaris in the outer pillar of high density polyethylene (HDPE), minute surface weldering plate machinery lifts, again with segmentum intercalaris machinery moment hot joining in the outer pillar of the polyethylene of two termination fusings.But, use the product of this explained hereafter in putting work, carrying and installation process, ftractureed easily by external force, cause thermal insulation pipe not reach heat insulation effect.
The model utility content:
The purpose of this utility model provides and presets the middle economize on electricity of the outer pillar of direct-buried insulated pipe elbow hot melt set of connection devices, it is not easy to crack that it can guarantee that the outer pillar of polyethylene is subjected to external force, thereby reach better effect, avoided thermal insulation layer being caused damage because of outer pillar weld cracking, influence heat insulation effect, thereby improved the working life that is incubated pipe fitting, the operation expense that has reduced pipe network greatly.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprise polyethylene Electric thermal smelting belt 1, tenminal block 2, two preset segmentum intercalaris 3 among the direct-buried insulated pipe elbow PE; Polyethylene Electric thermal smelting belt 1 presets among the direct-buried insulated pipe elbow PE among the PE between the segmentum intercalaris 3 segmentum intercalaris and is connected and stitches 4 and connect as one with two by heating, and tenminal block 2 is separately positioned on the both sides of polyethylene Electric thermal smelting belt 1.
The utlity model has following beneficial effect: it is easy to crack to guarantee that the outer pillar of polyethylene is subjected to external force, thereby reach better effect, avoided thermal insulation layer being caused damage because of outer pillar weld cracking, influence heat insulation effect, thereby improved the working life that is incubated pipe fitting, the operation expense that has reduced pipe network greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a process implementing structural representation of the present utility model;
Fig. 3 is the structural representation that the utility model presets segmentum intercalaris among the direct-buried insulated pipe spare elbow PE.
Embodiment:
Referring to Fig. 1-3, this embodiment by the following technical solutions: it comprise polyethylene Electric thermal smelting belt 1, tenminal block 2, two preset segmentum intercalaris 3 among the direct-buried insulated pipe elbow PE; Polyethylene Electric thermal smelting belt 1 presets among the direct-buried insulated pipe elbow PE among the PE between the segmentum intercalaris 3 segmentum intercalaris and is connected and stitches 4 and connect as one with two by heating, and tenminal block 2 is separately positioned on the both sides of polyethylene Electric thermal smelting belt 1.
Manufacturing process: two removing surfaces are clean and cut that segmentum intercalaris connects the seam alignment among the neat PE, polyethylene Electric thermal smelting belt lock ring is lived the middle segmentum intercalaris of alignment, then tenminal block 2 being connect electricity welds, connect electricity back polyethylene Electric thermal smelting belt 1 be heated with two preset that segmentum intercalaris 3 combines together among the direct-buried insulated pipe elbow PE, promptly finish technology.
The utlity model has following beneficial effect: it is easy to crack to guarantee that polyethylene outer protective pipe is subjected to external force, thereby reach better effect, avoided because of outer pillar weld cracking to the heat-insulation layer injury, affect heat insulation effect, thus greatly improved heat-insulating pipe fitting service life, reduced the operation expense of pipe network.
