Abstract
The utility model relates to a flange connecting device of a steel belt reinforced polyethylene helical bellows, comprising connecting flange main bodies which are plastically-injected at the two ends of the steel belt reinforced polyethylene helical bellows; the end surfaces of the connecting flange main bodies are sealing surfaces; connecting bolt holes of flange discs are arranged at the outer sides of the helical bellows on the flange main bodies; the connecting flange main bodies are respectively sheathed with one flange disc; and the two sections of the helical bellows to be connected are fixedly connected together by connecting bolts through the flange discs sheathed on the connecting flange main bodies. Due to application of the flange connecting device of the steel belt reinforced polyethylene helical bellows, a spiral structure of the end surface of the steel belt reinforced polyethylene helical bellows is changed, and a pipeline can be used for planar joint connection, so that the defects of connection of electric heating melting belt are made up, the pipeline connection quality can be effectively improved, and special requirements of engineering on pipeline connection are met. The metal flange discs are combined by adopting two semicircular metal flange pieces, only in pipeline connection, and the metal flange pieces are assembled on the flange main bodies to form the metal flange discs, so that the transportation of pipe materials is more convenient, and the transportation cost of the pipe materials can be effectively reduced.
Description
[technical field]:
The utility model relates to a kind of connection set of pipeline, and this class device is mainly used in the construction connection of steel band enhanced polyethylene (PE) helical bellows.
[background technique]:
Because steel band enhanced polyethylene (PE) helical bellows is the helical corrugation structure, the end face otch of tubing also is a helical, therefore in the construction of steel band enhanced polyethylene (PE) helical bellows connects, the main Electric thermal smelting belt that uses connects, Electric thermal smelting belt is twined a circle on the spiral interface of two tubing butt joints, the energising heating is welded then.Adopt the intensity of Electric thermal smelting belt connection interface lower, in particular cases because the sedimentation meeting on pipeline groove basis causes the phenomenon of interface cracking, quality to pipework produces harmful effect, and Electric thermal smelting belt connects needs the energising heating, in order to guarantee the safety of engineering construction, can not under the construction environment of band water, carry out operation, influence the construction speed of pipework.
[model utility content]:
The utility model purpose is to solve steel band enhanced polyethylene (PE) helical bellows connection interface intensity can not engineering demands under special circumstances, influence the pipework quality, can not submersible, influence problems such as engineering construction progress, a kind of steel band enhanced polyethylene (PE) helical bellows flange connecting apparatus is provided.
The steel band reinforced polyethylene spiral ripple pipe flange connecting apparatus that the utility model provides comprises, be directly injection-moulded in the adpting flange main body at steel band reinforced polyethylene spiral ripple pipe two ends by injection molding apparatus, the adpting flange main body adopts the polyethylene resin manufacturing, adpting flange main body end face is a sealing surface, be positioned at the helical bellows outside on the adpting flange main body and be provided with flange plate connecting bolt hole, flange plate of each suit on the adpting flange main body, two sections helical bellowses to be connected are connected and fixed with connecting bolt by the flange plate of suit on the adpting flange main body.Described flange plate is connected to form with bolt by two semicircular metal flange sheets.
Advantage of the present utility model and good effect:
Application of the present utility model has changed the helix structure of steel band enhanced polyethylene (PE) helical bellows end face, making pipeline can carry out plane interface connects, remedy the deficiency that Electric thermal smelting belt connects, can effectively improve the pipeline quality of connection, satisfied the specific (special) requirements that engineering connects pipeline.
The metal flange dish adopts two semicircle metal flange sheets to combine in the utility model, need not before injection moulding adpting flange main body, the metal flange dish to be enclosed within on the tubing, avoided in handling process metal flange to the damage of tubing, when pipeline connects, just the metal flange sheet is assembled in and forms the metal flange dish on the adpting flange main body, make the transportation of tubing convenient, can effectively reduce the tubing cost of transportation.

Among the figure, 1 adpting flange main body, 2 steel band enhanced polyethylenes (PE) helical bellows, 3 connecting bolts, 4 metal flange sheets, 5 gasket seals.
[embodiment]:
Embodiment 1:
The steel band enhanced polyethylene that the utility model provides (PE) helical bellows flange connecting apparatus, comprise adpting flange main body 1, adpting flange main body 1 adopts the polyethylene resin manufacturing, be directly injection-moulded in the two ends of steel band enhanced polyethylene (PE) helical bellows 2 by special-purpose injection molding apparatus, the end face of adpting flange main body is a sealing surface, be positioned at the helical bellows outside on the adpting flange main body and be provided with flange plate connecting bolt hole, metal flange dish of each suit on the adpting flange main body, two sections helical bellowses to be connected are connected and fixed with connecting bolt 3 by the flange plate of suit on the adpting flange main body.Described flange plate is connected to form by two semicircular metal flange sheet 4 usefulness bolts.
