Abstract

The invention belongs to pipeline processing tools, and specifically relates to a connector for a draining pipeline. The connector for the draining pipeline comprises a sleeve of which the inner wall is provided with an annular block, wherein two sides of the annular block are correspondingly abutted with corrugated pipelines; one end of the sleeve is a port expansion end. The connector further comprises a sleeve ring, wherein two annular walls which extend toward the center of the sleeve ring are arranged on the sleeve ring; one annular wall is in shape fitting with the port expansion end, and the inner diameter of the other annular wall is equal to the diameter of a corrugation sunken part of the corresponding corrugated pipeline; the two annular walls are opposite in directions; the sleeve ring is positioned at the port expansion end which is positioned in an inner chamber that is encircled with the two annular walls. The connector can overcome the technical defect of easy opening in the prior art, and can limit a combining part of the pipeline from the outside of the pipeline so as to prevent opening from occurring.

Description

Drainage pipeline adapter
Technical field
The invention belongs to pipeline processing apparatus, particularly drainage pipeline adapter.
Background technology
Heavy caliber buried steel band enhanced polyethylene (HDPE) helical corrugation tubing is a kind of novel municipal drainage blowdown Pipeline, it utilizes the elastic modelling quantity that steel are higher, uses special production equipment, steel band is converted into inverted U, and passes through crimping machine The steel band of inverted U is curled into the curvature diameter of different size tubing, and under hot melt state, the binding agent utilizing steel strip surface will The polyethylene material embryo of inside and outside layer is bonded into one effectively with steel band, produces inner wall smooth, ectonexine is polyethylene material Material, intermediate layer are steel band enhanced polyethylene (HDPE) the helical corrugation tubing of steel band, have both remained polyvinyl piping materials corrosion-resistant, no The advantages such as fouling, water resistance coefficient is little, it is easy to connect to install, length in service life.For keeping the mechanical property of steel band, cut at tubing Time need to ensure that steel band does not destroys, therefore tubing section is not the axis perpendicular with tubing, and thus bring is tubing even Must take time when connecing and the end face of interconnective two tubing is alignd, reduce the gap between two tubing as much as possible, and Ensure the concentricity of two tubing.
Because the connection of steel band enhanced polyethylene (HDPE) helical corrugation tubing is to use hot melt strip heating bond vitrified skill Art, will polythene material produce hot melt strip be wrapped on the connecting sewing between two tubing, by the resistance wire of hot melt strip lead to Electrical heating, melts the polythene material of tube surfaces and the polythene material of hot melt strip, by External Force Acting, by tube surfaces Polythene material and the polythene material of hot melt strip is the most molten is integrated, complete the connection of tubing after cooling.Therefore, the company of need Whether the concentricity i.e. tube surfaces connecing two tubing is the most smooth, have space will directly affect the connection matter of tubing with hot melt strip Amount.
A kind of large-diameter pipeline installation positioner is disclosed for solving above-mentioned technical problem Chinese patent CN201547391, Including upper work surface, lower work surface, screw rod bushing, wherein going up work surface lower end and be fixed with upper screw rod, lower work surface upper end is fixed with Lower screw mandrel, described upper screw rod matches with screw rod bushing upper end, and described lower screw mandrel matches with screw rod bushing lower end.
Above-mentioned patent is close to two by the upper work surface consistent with pipe material inner wall curvature and lower work surface to be needed to connect The inwall of tubing, it is ensured that the flatness of tube surfaces, is minimized the space of hot melt strip with tube surfaces.But still suffer from as Lower technological deficiency:
When connecting two helical corrugation tubing, corrugated pipe joint inwall is outwards pushed up by described upper and lower work surface to be stretched, if top Degree of extending through, easily there is the opening expanded outwardly, so bonds opening part, described corrugated tube even by hot melt strip in described junction The most easily there is crackle (material of hot melt strip is poorer than corrugated tube) in the joint of material, and opens described in not yet occurring in prior art preventing The adapter that mouth occurs.
Summary of the invention
The technical problem to be solved is to provide a kind of corrugated pipe joint and flared opening occurs Drainage pipeline adapter.
In order to solve above-mentioned technical problem, the present invention provides following technical scheme:
Drainage pipeline adapter, including sleeve pipe, internal surface of sleeve pipe is provided with ring block, and the both sides of described ring block are respectively used to and ripple Pipeline docks, and one end of described sleeve pipe is flared end;Also include that a collar, the described collar are provided with two and extend to collar center Annular wall, one of them annular wall and described flared end form fit, the internal diameter of another annular wall and corresponding corrugated conduit Its ripple cave in place chi footpath identical, two annular wall towards relatively;The described collar is positioned at described flared end, flared end It is in and is enclosed in the inner chamber set by two annular wall.
Compared with prior art, the method have the advantages that
1., when installing, need to respectively penetrate in sleeve pipe by two screw thread corrugated tubes, it is desirable to the mouth of pipe of two sleeve pipes bears against The both sides of ring block, will install the described collar in described flared end, it is desirable to described flared end is in two annular wall and is enclosed and set In inner chamber.An annular wall and described flared end form fit, the internal diameter of another annular wall and corresponding ripple in two annular wall The cave in chi footpath at place of its ripple of stricture of vagina pipeline is identical, two annular wall towards relatively, it is possible to by annular wall patch and The outside of described flared end, another annular wall is inserted into described ripple and caves in place.So collar just can be by described annular wall Strong fix is between flared end and above-mentioned ripple are caved in.
2., if using the Pipe installing localizer disclosed in Chinese patent CN201547391, the joint of two pipelines is opened Begin outwards occur dehiscing, described sleeve pipe can be driven to separate with the collar, owing to sleeve pipe two ends are each attached on pipeline, so sleeve pipe with The relative position inconvenience of pipeline, and the described collar is positioned at flared end and corresponding ripple and caves in place, so home position is the most relatively Stable.Then pipeline can be produced and open outside counteracting force restriction conduit joint by sleeve pipe and the collar (including annular wall), thus keeps away The appearance dehisced described in having exempted from.
Further, the described collar includes the upper half collar and the lower half collar, detachably connects between the upper half collar and the lower half collar Connect.
Compared with the circular ring of integration, the collar is made split design and is more beneficial for installing.
Further, described inner chamber is additionally provided with and coordinates with described flared end, for fully taking up the ring body of described inner chamber.
If the idle space of described inner chamber is too big, the deformation space of (helical corrugation) pipeline of relevant position also can be with Increase;In order to the deformation quantity of described pipeline is made certain constraint, spy sets up described ring body, for being accounted in described idle space According to, reduce the deformation space of (helical corrugation) pipeline of relevant position.
Further, described ring block is provided with annular mounting groove, is provided with and mounting groove form fit in described mounting groove Sealing ring.
In order to improve the sealing property of drainage pipeline adapter, special increase sealing ring, it is to avoid the current in pipeline are excessive.
