Abstract
The inventive spiral pipeline consists of a spiral pipeline body and a connecting member fixed at one end or two ends of the spiral pipeline body for connecting the end ports. One end of the screw end port connecting member is a screw end port and the other end is a flat port. The inventive manufacture method includes the following steps of heating melting the screw end ports of the connecting member and the spiral pipeline body and welding two screw end ports together under a certain pressure to be a integral one, at last changing the screw end port of the spiral pipeline body into the flat port to realize the flat port connection between the pipelines.
Description
Technical field
The present invention relates to a kind of Plain end scroll type pipeline and its preparation method, belong to plastic pipe and connect processing technique field.
Background technique
Spiral type pipes such as existing steel band reinforced spiral ripple pipe, hollow wall volute generally adopt spiral to twine disposable continuous forming process, because manufacturing process, its pipe end is a helicoid.Because port shape is special, structural pipe wall and form complicatedly,, had a strong impact on further applying of spiral type pipe so be connected difficulty between pipeline and the pipeline.Present Placement mainly contains and extrudes welding, the electric smelting tape welding connects and mechanical connection etc.Extrude be welded to connect the jointing bulk strength and rigidity low, and because of the plastic draining pipe wall is very thin, it is little to connect area, therefore, the port dislocation can have a strong impact on welding quality, dislocation also can cause and can't weld when big.It is narrower that the electric smelting tape welding connects face of weld, higher to two pipe end place circularity and size tolerance requirements, also high to the surface smoothness requirement at port trough place, and the circularity of spiral type pipe and size deviation are bigger, therefore the outer surface of tube wall out-of-flatness, often causes interface to leak or phenomenon of rupture.Mechanical connection is to adopt Hough formula clip that the ripple of two several pitch of pipe end is coated, trough fills up with rubber stopper, realize connecting and sealing, this join strength and rigidity are better, but because of sleeve covers and rubber filling area all bigger, connect waste material, sleeve and bolt preservative treatment expense increase simultaneously, and link cost height, efficient are low.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in design, the strength and stiffness height, the interface steady quality, welding cost is low, widely applicable Plain end scroll type pipeline and its preparation method.
The present invention is a plain end screw pipe, comprises the spiral type pipe body, it is characterized in that being welded with spiral port connector element on the spiral port of spiral type pipe body one or both ends, makes the spiral port of spiral type pipe body be converted to flat mouthful; One end of described spiral port connector element is the spiral port, and the other end is flat mouthful.
Described spiral port connector element can be made cylindrical tube by plastic materials through extruding technologies such as winding, injection moulding, compacting earlier, adopt helical cut technology that cylindrical tube is cut into symmetrical two sections again, forming two one ends is the spiral port, and the other end is the spiral port connector element of flat mouth.
Also can be provided with the convex edge of band seal groove on the flat mouthful of end face of described spiral port connector element,, and improve its connection sealing with the flange head clip connected between convenient two plain end screw pipes.
Also can be provided with the convex edge of embedded resistance wire on the flat mouthful of end face of described spiral port connector element, can be used for two electric smelting between the plain end screw pipe and be welded to connect.
The processing method of plain end screw pipe of the present invention is: adopt spiral port heater, to the spiral port of spiral port connector element and the spiral port heating and melting of spiral type pipe body, two spiral ports are welded together, form a plain end screw pipe integral body.
Described spiral port heater can place the heating pipe in the cast aluminium screw type opening annulus for by cast aluminium screw type opening annulus, electric control box, the spiral port electric heater that the electric wire of connection cast aluminium screw type opening annulus two ends and electric control box etc. constitute.Described spiral port heater can be for by cavity screw type opening annulus, be circulated in the conduction oil of cavity screw type opening annulus inside, conduction oil is heated and thermostatically controlled oily temperature control case, connect the spiral port oil heater of the formations such as heat-conducting oil pipes of cavity screw type opening annulus two ends and oily temperature control case.
The present invention is by welding fixedly spiral port connector element on the spiral port of spiral type pipe body one or both ends, realized of the conversion of the spiral port of spiral type pipe to flat mouth, reasonable in design, be applicable to the processing of the spiral type pipe of various models such as steel band reinforced spiral ripple pipe, hollow wall volute.Compared with prior art, have following outstanding advantage and good effect:
1, can make things convenient for and economic and practical clip, electric smelting is welded to connect, it is promoted in engineering becomes possibility;
2, simple, the quick construction of connection device has reduced construction equipment, has improved installation rate, and clamp band type connects the demand of also having saved the job site power source, makes on-the-spot the installation become very convenient;
3, connection technology is simple, has guaranteed that construction interface steady quality is reliable, has guaranteed that sewage conduct does not have leakage;
4, overcome the low shortcoming of the anti-inside and outside pressure degree of interface end face, its flat mouthful end face not only has higher rigidity and bears external pressure, also has enough intensity, adapts to the needs that pressure waterpipe engineering is arranged.
