Description
Technical field
The utility model discloses the linkage structure in a kind of steel wire mesh frame plastic composite tube road.
Background technique
The steel wire mesh frame polyethylene compound pipe is a kind of novel high-tech environmental-protecting chemical tubing of domestic rise over past ten years.It is that the reticular structure that forms with winding braiding about the high tenacity Coppered Steel Wire is a skeleton; With the high density polyethylene (HDPE) is body material (polyethylene is a PE100 level pipeline PP Pipe Compound); Utilize modified poly ethylene---adhering resin, pass through continuous, compound withstand voltage, the internal and external anti-corrosive chemical building material of new generation that forms of gradation extrusion molding on production line.This product specification is φ 63～φ 630mm, is widely used in industries such as municipal plumbing, petrochemical industry, electric power, coal and mine.
The plastic pipe kind is a lot of at home at present, and the feedwater field mainly is to be main with steel wire mesh frame plastic composite tube and PE tubing.PE pipeline Placement mainly contains three kinds of Placements at present: the weldering of hot melt tubing, the butt welding of hot melt pipe fitting, the welding of thermofusible spigot formula; Steel wire mesh frame plastic composite tube mainly adopts the electrothermal smelting tube welding; This Placement is widely used at present; But the pipe fitting cost is too high, and the molten Placement of this electric heating has several shortcomings: one, inconvenience is installed, and the power supply difficulty is looked for on-site; Two, maintenance is inconvenient, is difficult to during welding guarantee welding quality, and can not uses this Placement in mining pipeline industry.Mining pipe is main with flange connection mainly; It is will carry out flange flange is stamped that flange connects prerequisite, or is exactly through the hot melt Placement flange cover to be connected earlier with tubing to use this mode, and still also depositing quality of connection can not guarantee; And complex process, cost is high.
The market competition more and more fierce of present whole plastic pipe; To quality of product require increasingly high; Who can better control cost of production and installation cost under the prerequisite of the overall situation of Market competition and equivalents equal quality; Who will lead the demand in market, becomes maximum winner.To above characteristics; Though many plastic pipe manufacturing enterprises and plastic pipe applying unit have all been carried out a large amount of research; Hope can be developed that a kind of plastic pipe link cost is low, quality good, convenient and fast connection, more safe and reliable linkage structure are installed, but does not all have to obtain gratifying effect.
The model utility content
The purpose of the utility model is to overcome the shortcoming of existing technology; A kind of novel Anknupfungskeregriff is proposed; A kind of linkage structure of steel wire mesh frame plastic composite tube; The present relatively link of this linkage structure is material benefit more economically from the angle of installation cost, and preparation cost is low, product performance and quality are improved a lot, the composite pipe of being produced seal with mounting structure on safer, reliable.
The purpose of the utility model realizes through following technological scheme: a kind of steel wire mesh frame plastic composite tube pipeline connecting structure; Comprise pipeline; It is characterized in that: be provided with the pipe joint of inside and outside cover ironcasting, flexible quick connector, rubber seal formation, said flexible quick connector is provided with groove, and said rubber seal is arranged in the groove of flexible quick connector; Said overcoat ironcasting tightly is enclosed within on the outer tube wall of said pipe end; Interior cover ironcasting one end plug-in mounting is fastened in the said pipe end, and the other end of interior cover ironcasting stretches out outside pipe end, and the interior cover ironcasting end that stretches out outside pipe end is provided with flange; Flexible quick connector shrinks through screw rod on the flange that connects the interior cover ironcasting that is clamped on two pipeline ends, rubber seal and flange crush seal in the flexible quick connector groove.
Cover ironcasting outer wall is provided with and prevents that the outer pawl type that moves back that slips colludes in said.
Said pipe joint is processed by the strong ductile castiron material of corrosion-resistant antiacid basicity.
The utility model is simple in structure, and preparation cost is low, more economically the material benefit, product performance and quality are improved a lot, the composite pipe of being produced seal with mounting structure on safer, reliable.Adopt pipe joint; (earlier the overcoat ironcasting is enclosed within on the outer tube wall of said pipe end through the external hydraulic snap close machine on-the-spot tubing two ends mouth of pipe is locked after tubing (steel wire mesh frame plastic composite tube road or abbreviation pipeline) is produced; Adopt push-bench that interior cover ironcasting one end is pushed in the pipe end then; To there be the pipeline end of inside and outside cover ironcasting to be put into again and push the reducing sealing and fixing in the necking machine); Requiring to be dealt into the building site according to customer order then gets on; Being connected through the ironcasting flexible quick connector in the installation process of building site between tubing and the tubing tighten two tube heads, in flexible quick connector inside rubber seal is housed, and the screw rod through the contraction flexible quick connector seals rubber seal extrusion-deformation to two tube heads.This Placement makes that the connection between two steel wire tubes is more firm.
The effect and the advantage of the utility model also have:
(1) the utility model adopts the ductile castiron material preparation to form, and in selection, selects the strong cast iron materials of corrosion-resistant antiacid basicity, and this material material is processed simple and convenient, quality better well; With traditional Placement relatively, saved product sealing process, trimming process step because this Placement from first to last all is to adopt mechanical connection, so saved the welding machine of prior welding mode and on-site the power supply difficulty problem such as look for.
(2) the utility model structure is firm; It is good to install back pipeline secure seal performance, if it is more convenient than traditional Placement to find that most importantly tubing has problems such as leakage or explosion to repair, if the words of traditional electrothermal smelting tube Placement; Must amputate problematic pipe fitting during maintenance; But tubing will shorten after amputating, and so will increase by two electrothermal smelting tubes, when having improved maintenance cost, has strengthened maintenance difficulty.
(3) device structure is simple, and the complete equipment low cost of manufacture is easy to accepted by numerous enterprises.The most crucial part of entire equipment is exactly that tubing two ends opening part is passed through the necking machine reducing with overcoat ironcasting extrusion-deformation fastening tubing, makes it more firm.Liner ironcasting appearance has the pawl type colludes, this part mainly be liner at internal surface of pipe, when through the necking machine reducing time, the flute profile of liner ironcasting is colluded snap in plastic tube inside to seal with overcoat ironcasting extrusion-deformation fastening tubing.
(4) be exactly two sealing problems between the tubing then, what the utility model adopted is that flexible quick connector and rubber seal come it is sealed, not only firmly but also make things convenient for; The total amount of parts is few, and is simple in structure, easy for installation, so manufacture cost is lower.
