Abstract
The utility model relates to a pipeline of material transport in trades such as wide application in building, colliery, electric power also includes the pipeline that uses on the concrete pump truck. It is including the steel pipe, its characterized in that: the steel pipe is lined with a polyurethane rubber pipe as a protective layer of the steel pipe lining. The inner wall of the polyurethane rubber tube of the lining is provided with a spiral line. And the end openings of the steel pipes are wrapped inside by polyurethane protective layers at two ends of the steel pipes. The utility model aims to solve the problem that the pipe wall of the pipeline for conveying materials is easily abraded, abraded and leaked due to friction. Through the utility model discloses an implement, the pipeline inner wall will be effectively protected, and its life will be higher than not lining the gluey pipeline more than 5 times, simultaneously, because the steel pipe both ends are equipped with the polyurethane protective layer, not only can improve the life of steel pipe, also can make pipeline elasticity link up, connect better.
Description
One, technical field: the pipeline of mass transport in the industry such as the utility model relates to and a kind ofly is widely used in building, colliery, electric power also comprises the pipeline that uses on the concrete mixer.
Two, background technique: at present, in industries such as building, colliery, electric power, material conveying pipe adopts common steel tube more; the steel pipe the inside does not have protective layer; through use after a while, because the frictional ratio between material and the pipeline is more serious, tube wall is easy to be worn, grind and becoming useless the pipe with Louing.Steel pipe is not long working life, and waste of material is more serious, increases the operation cost of enterprise.
Three, summary of the invention:
1, goal of the invention: the utility model provides a kind of spiral polyurethane line with rubber pipe, the problem that the pipeline that its purpose is to solve conveying material exists because of aspects such as the friction tube wall are easy to be worn, to grind leakage.
2, technological scheme: the utility model is achieved through the following technical solutions:
A kind of spiral polyurethane line with rubber pipe, it includes steel pipe, it is characterized in that: at inner lining of steel pipe the polyurethane sebific duct is arranged, as the protective layer of inner lining of steel pipe.
On the inwall of the polyurethane sebific duct of liner, be provided with helix.
At the two ends of steel pipe, the port of steel pipe is wrapped in the inside by the polyurethane protective layer.
3, advantage and effect: after material conveying pipe adopts the technological scheme that the utility model proposes, inner-walls of duct will be effectively protected, and will exceed 5 times or more than line with rubber pipeline not its working life, reduces operation cost of enterprises greatly.Simultaneously,, not only can improve the working life of steel pipe, pipeline elasticity is connected, connect better because the steel pipe two ends are provided with the polyurethane protective layer.
Four, description of drawings: accompanying drawing 1 is the main form structure schematic representation of the utility model;
Accompanying drawing 2 is the utility model part section structural representation.
Five, embodiment: the utility model is to adopt following scheme implementation:
The utility model is that the screw type urethane rubber of cast has formed polyurethane sebific duct 1 on the interior wall liner of steel pipe 2 as protective layer on the inwall of steel pipe 2.The urethane rubber wear-resisting property is very excellent, and its wear resistance is higher 9 times than natural gum, and is higher 1～3 times than butadiene-styrene rubber, uses under the violent condition of abrasion, and urethane rubber part wear resistance exceeds more than 10 times than other rubber parts.Be provided with polyurethane protective layer 4 at the two ends of steel pipe 2, the port of steel pipe 2 is wrapped in the inside.Simultaneously, the helical structure of polyurethane line with rubber inwall forms the helix 3 of polyurethane sebific duct 1, " rifle " in the similar gun barrel gun barrel, and its effect is the material of conveying is rotated as shell and to have moment of momentum.Because law of conservation of angular momentum, the material of rotation are difficult for departing from and carry along straight line always, the collision of minimizing and polyurethane line with rubber, the working life of further improving the line with rubber pipe.
