Abstract
The utility model discloses a connecting device between ports of a spiral corrugated steel pipe. The connecting device is characterized in that 2-5 spiral ripples on a pipe body on abutting ends of two sections of spiral corrugated steel pipes are respectively pressed into annular ripples, two annular corrugated pipe loops matched and overlapped with the annular ripples are respectively provided, and are separated into two halves along the axial direction, a vertical flange is provided along a separating notch, a connecting hole is arranged in the flange, two separating bodies are connected through a bolt, axial abutting ends of the two annular corrugated pipe loops are provided with vertical flanges, connecting holes are arranged in the flanges, a sealing gasket is arranged between the vertical flange, and the two sections of spiral corrugated steel pipes are abutted by using the bolt.
Description
Technical field
The utility model relates to the connection between the pipeline, the connection set between especially a kind of spiral corrugated steel pipes port.
Background technique
Corrugated steel tube is to conventional pipelines, upgrades the ideal product that substitutes such as cast iron tube, welded pipe, cement pipe, plastic tube etc.The ripple of corrugated steel tube comprises that annular corrugated and helical corrugation structure, the port of annular corrugated steel pipe be circular, docks more conveniently between two segment pipes, comprises bayonet joint, groove type connection etc.And the port of spiral corrugated steel pipes is non-circular (ripple is arranged), and directly reliability and the sealing of docking are not high, so the reliability of spiral corrugated steel pipes pipeline section joint and sealing become the major issue that faces in the whole pipe-line system.
Summary of the invention
The utility model provides the connection set between a kind of spiral corrugated steel pipes port, realizes reliable the connection by the ring bellows kink.Realize by the following technical solutions: the connection set between a kind of spiral corrugated steel pipes port, it is characterized in that: 2～5 helical corrugations at the pipe shaft place, butt end of two sections spiral corrugated steel pipes are pressed into respectively the ring ripple, two ring bellows kinks with the superimposed coupling of this ring ripple are set respectively, this ring bellows kink is split into two halves vertically, be provided with vertical flange along the subdivision otch, flange is provided with attachment hole, by bolt two subdivision bodies are connected, the axial butt end of two ring bellows kinks is equipped with vertical flange, flange is provided with attachment hole, be provided with gasket seal between the two vertical flange, by bolt two sections spiral corrugated steel pipes docked.
Advantage of the present utility model and beneficial effect:
The pipe shaft position, butt end of spiral corrugated steel pipes is made into annular corrugated, is superimposed on spiral corrugated steel pipes end annular corrugated with in two circular arc ripple kink again, fit tightly with steel tube surface.The butt end of annular corrugated kink is provided with vertical flange just as flanged surface, between two flanged surfaces sealing gasket is set, not only convenient connection, and also sealing improves greatly.The mode that lap joint flange is bolted is not destroyed the surface quality of spiral corrugated steel pipes, has effectively guaranteed intensity simultaneously.Arrange respectively that according to the diameter of spiral corrugated steel pipes wearing of some joins the hole on kink, can satisfy like this requirement of different densities, join strength, realize the reliable connection between spiral corrugated steel pipes.
Description of drawings
Accompanying drawing 1 is the coupled condition schematic representation of two spiral corrugated steel pipes;
Accompanying drawing 2 is structural representations of lap joint flange and burst joint thereof.
Embodiment
Referring to Fig. 1,2～5 helical corrugations in connecting end pipe shaft position of two spiral corrugated steel pipes 1 are pressed into annular corrugated with forming machine, to be provided with the ring bellows kink 2 of vertical flange (flange) and the annular corrugated part of steel tube end part fits together closely, place axial bolts 5 by the connection hole of wearing on the flange after placing sealing gasket 4 between ring bellows kink 2 and spiral corrugated steel pipes 1 surface and between the two vertical flange, tighten up and adpting flange with nut 3, realize the reliable connection between two spiral corrugated steel pipes, installation is convenient and swift.
Referring to Fig. 2, the main body of ring bellows kink 2 equally is the hoop corrugated with the end body section of spiral corrugated steel pipes 1, and the flange (can adopt welding) that its connecting end is provided with laterally consists of flange connection surface.Convenient for installation, ring bellows kink 2 is split into the two halves arc plate, the subdivision incision is by welding angle steel 6 and wear connection hole, bolt, nut, and the reliable connection between realizing between 2 annular ripple kinks forms the integral ring-shaped bellows kink 2 on the connecting end pipe shaft position outer surface that is coated on spiral corrugated steel pipes 1 afterwards.
