Description
Technical field
The utility model belongs to heating system equipment mounting technique field, particularly relates to a kind of electric preheating equipment and heat supply steel pipe tie point device.
Background technique
In urban heating pipeline construction, its core is that temperature difference when running for heat supply pipeline is comparatively large, takes measures the axial temperature stress reducing pipeline, thus improves the safety and reliability that heating system runs.In traditional heat supply pipeline work progress, usually adopt and reinforcement process is carried out to heat supply pipeline, application compensator and fixed support, the dilatancy that extraction duct produces in running, reduce the axial stress of pipeline.But this method existing defects:, owing to having widely applied compensator and fixed support in heat supply pipeline, add construction cost, reduces the Security of heat supply pipeline; Two, heat supply pipeline compensator anticorrosion construction difficulty is large, and easily intakes; Three, heat supply pipeline compensator is fragile, and rate of fault is high.
Summary of the invention
The purpose of this utility model is: design a kind of connection set, and this apparatus structure advantages of simple effectively can overcome the deficiency of existing method of construction, improves the efficiency of construction of urban heating pipeline electric preheating, reduces cost of production.
The technical solution of the utility model: electric preheating equipment and heat supply steel pipe tie point device, comprise heat supply steel pipe and welding screw disposed thereon, and cable, described welding screw settles connection set from bottom to top successively, packing ring and hexagon nut; Described connection set forms by with the connection handle in part hollow chamber and the connecting head of band annular distance, and connecting head entirety is in flat; Connection handle hollow cavity part is connected with cable, and the annular distance on connecting head then matches with welding screw.
Beneficial effect: the utility model can be connected with heat supply pipeline electric preheating equipment easily, meanwhile, improves the heat transference efficiency of electric preheating equipment, reduces cost of production, improve efficiency of construction.The utility model is applicable to the connection of all size urban heating pipeline and electric preheating equipment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the main TV structure schematic diagram of connection set of the present utility model.
Embodiment
Embodiment 1, electric preheating equipment and heat supply steel pipe tie point device, as shown in Figures 1 and 2, comprise heat supply steel pipe 7 and welding screw 1 disposed thereon, and cable 6, described welding screw 1 settles connection set 4 from bottom to top successively, packing ring 2 and hexagon nut 3; Described connection set 4 forms by with the connection handle 9 in part hollow chamber 5 and the connecting head of band annular distance 8, and connecting head entirety is in flat; Connection handle hollow cavity 5 part is connected with cable 6, and the annular distance on connecting head 8 matches with welding screw 1.Described annular distance 8 inwall can arrange the internal thread matched with welding screw 1.
In practice, with electric capacity energy-storage type double screw-bolt welding process, welding screw is fixed on urban heating steel pipe end; The cable of electric preheating equipment one end is connected with connection set; By the annulus cover (annular distance) of connection set on welding screw, and tighten fixing with packing ring and hexagon nut.
Claims (2)
1. electric preheating equipment and heat supply steel pipe tie point device, comprise heat supply steel pipe and welding screw disposed thereon, and cable, it is characterized in that: on described welding screw, settle connection set successively from bottom to top, packing ring and hexagon nut; Described connection set forms by with the connection handle in part hollow chamber and the connecting head of band annular distance, and connecting head entirety is in flat; Connection handle hollow cavity part is connected with cable, and the annular distance on connecting head then matches with welding screw.
