Abstract
The utility model discloses a composite anti-corrosion drainage connecting pipe; two ends of the connecting pipe are respectively provided with a plug and a socket; the composite anti-corrosion drainage connecting pipe is characterized in that an anti-corrosion high-molecular material layer is attached on the internal wall of the connecting pipe; the plug and the socket at two ends of the connecting pipe are coated with high-molecular material liner bodies integrally molded with the anti-corrosion high-molecular material layer. The composite anti-corrosion drainage connecting pipe has a rational structure design and good sealing performance; the construction difficulty for the connection of the drainage pipe is effectively reduced and the sealing effect of the connection is improved, so that the anti-corrosion performance of the drainage pipe after connection can be balanced and the leakage problem of the fluid in the pipeline can be prevented. The composite anti-corrosion drainage connecting pipe has long service life and low manufacturing cost and can be widely applied to the connection of various kinds of drainage pipes with anti-corrosion high-molecular material liners.
Description
Technical field
The utility model belongs to logical draining with pipeline and interconnection technique thereof, the concrete composite anti-corrosive drainage connecting pipe that relates to a kind of plumbing use.
Background technique
In the existing technology, mostly the discharge pipe line that is used for city, rural area and water conservancy projects etc. is the inorganic material pipeline of reinforced concrete material, perhaps is the straight-tube shape pipeline of ceramic structure.The cost cost of such pipeline is low, and body is sturdy and durable, the arterial drainage pipeline of written city, road, water conservancy projects etc.But because inorganic material pipeline self characteristics, for example inner tube wall is more coarse, pipeline inner fluid resistance is big, and the draining flow velocity is slow and easy sedimentary pile deposition is husky.The corrosion resistance of particularly existing inorganic material pipeline is relatively poor; The rainwater that causes along with atmosphere environment is acid increase and draining in the acid and alkali substance that dissolves increase; This has caused such pipeline to be easy to the reduction in strength problem that inside is corroded and is caused in use occur, thereby has cut down greatly the working life of discharge pipe line.The operation of such pipeline when connecting is also very complicated, also is easy to occur leakage problem.
On February 17th, 2010, disclosed Chinese patent ZL200920009194.6 provided a kind of reinforced concrete drainage connecting pipe of composite anti-corrosive; Main body is the hollow body of concrete or reinforced concrete; The two ends of hollow body form socket and joint socket respectively; Insert to hold through port between body and the body and be connected, all be covered with antiseptic rubber on the socket at the two ends of each hollow body and the joint socket, the joint socket of another body of body socket insertion; All surface of contact all are Elastic Contact of rubber and rubber, and also are provided with rubber seal between socket and the joint socket.This connecting tube has that rigidity intensity is high, the resistance to compression load big, good seal performance, the big advantage of strong, the anti-pipeline foundation amplitude of deformation of corrosion resistance; But this connecting tube need be put into rubber seal in the joint in application; And the placement location of rubber seal and precision are bigger to the sealing effect influence; And existing site operation peopleware and environment have the assurance of being difficult to place precision, therefore are easy to cause the artificial defect of sealing joint poor performance.
The model utility content
The utility model provides a kind of reasonable in design; The composite anti-corrosive drainage connecting pipe that sealability is good, it can effectively reduce the difficulty of construction that waste pipe connects, and improves the connection sealing effect; Make the antiseptic property after waste pipe connects balanced, stopped the leakage problem of pipeline inner fluid.Its long service life, fabricating cost is low, can be widely used in various waste pipes with anticorrosion macromolecular material liner and connects.
The technological scheme that the utility model adopted is following:
A kind of composite anti-corrosive drainage connecting pipe; The two ends of this connecting tube are provided with plug and socket respectively; The inwall applying that it is characterized in that said connecting tube is provided with an anticorrosion polymer material layer, and the plug at these connecting tube two ends and socket coat respectively and be provided with and the integrated macromolecular material cushion body of said anticorrosion polymer material layer.
In the embodiment, said plug is the formed inner sleeve of the inside step type annular recess in connecting tube end, and the macromolecular material cushion body that this inner sleeve outer wall coats is formed with the elasticity fin around this inner sleeve.
In one mode of execution, the outer wall of said inner sleeve is provided with groove, and macromolecular material cushion body correspondence is provided with integrated bump and cooperates with said groove setting-in.
In another mode of execution, said socket is the formed outer sleeve of the outside step type annular recess of connecting tube inner end diameter, and the macromolecular material cushion body that this outer sleeve inwall coats is formed with the elasticity fin around this outer sleeve inwall.
In the mode of execution, the inwall of said outer sleeve is provided with groove again, and macromolecular material cushion body correspondence is provided with integrated bump and cooperates with said groove setting-in.
This composite anti-corrosive drainage connecting pipe adopts the plug and the jack design of the stack that partially overlaps, and the macromolecular material cushion body that covers plug and socket through the connecting tube two ends plays preferable preserving and sealing effect.Contact the elasticity fin that annular is provided with on the end face with socket at plug; Can save the use of existing rubber gasket; Simultaneously with the position and the fixed size of the integrated elasticity fin of macromolecular material cushion body, its precision when plug docks with socket improves greatly and has significantly improved sealing effect simultaneously.In order to improve the adhesive strength of macromolecular material cushion body and inner sleeve and outer sleeve, the mode of distributed and arranged groove is combined closely the macromolecular material cushion body with it on inner sleeve that can be through entire body outside inorganic material and the outer sleeve in practical application.
The beneficial effect of the utility model is, this composite anti-corrosive drainage connecting pipe reasonable in design, and sealability is good; It can effectively reduce the difficulty of construction that waste pipe connects; And improve the connection sealing effect, and make the antiseptic property after waste pipe connects balanced, stopped the leakage problem of pipeline inner fluid.Its long service life, fabricating cost is low, can be widely used in various waste pipes with anticorrosion macromolecular material liner and connects.
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.
