Abstract
A great plastic water pipe features that its wall is made up of PE plastics as main body, steel wire net as skeleton and special enamel for coating on its surface, and a pair of screw joints are at its both ends for linking and sealing. Its diameter is 0.5-6 m. The thickness of pipe wall is 5-50 cm. Its advantages are high toughness, flexibility and strength, high anticorrosion performance, and easy installation and sealing.
Description
The present invention relates to a kind of water supply water pipe, particularly relate to a kind of large-scale PE plastic water pipe pipe fitting.
In the prior art, large-scale water supply water pipe generally is to be made by cement or metal, though they have higher intensity, their anti-crawl agentdefiection degree is relatively poor, particularly cement pipe.Because large-size pipe when provided underground, is subjected to the pressure effect from ground morely, the amount of deflection that pipe fitting bears is limited, and the pipe fitting phenomenon of rupture takes place easily; In the bigger area of some temperature difference, cement pipe also regular meeting causes explosion because of the cause of expanding with heat and contract with cold; In addition, the weight of cement pipe is big, and loading and unloading are inconvenient.And the corrosion resistance of metal tube is relatively poor, easily gets rusty and pollutes, and influences working life.The existing plastic tube of China adopts extruding-out process to make, and mostly is miniature valve, but continuous reeling one-tenth dish; Existing big plastic water supply water pipe comprises two kinds of nontoxic hard polvinyl choride pipe and polyethylene pipes, and the former production has comparatively strict sanitation performance requirement, and the connection between two pipes need be used pipe joint; And the latter is higher owing to technical requirements, and the largest tube external diameter also only reaches 0.5m, domestic not system development as yet so far.
The purpose of this invention is to provide a kind of large-scale PE plastic water pipe pipe fitting, make it both have good toughness and anti-crawl agentdefiection degree, can satisfy requirement of strength again, and the connection between two pipes need not pipe joint.
The objective of the invention is to realize: a kind of great plastic water pipe by following technical measures, it is characterized in that: the tube wall of described great plastic water pipe is a matrix with the PE plastics, with the reinforcing mesh is skeleton, and adopts special slush moulding equipment slush moulding, once-through, the pipe fitting bore is 0.5～6m, wall thickness is 5～50cm, and its two ends have a pair of threaded coupling, and promptly an end wherein has outside thread, the other end has the internal thread that matches with outside thread, so that sealing is installed.Described reinforcing mesh has plastic substrate to be reinforced and the resistance to compression effect, and the mechanical property of plastic tube is improved greatly; Pipe thickness can change as requested.
Pipe fitting bore preferable range of the present invention is between 0.6～2.5m.
Large-scale PE plastic water pipe pipe fitting described in the present invention can be straight shape pipe, also can be various connection pipe fittings, as elbow, three-way pipe, four-way pipe, valve etc., for use in various occasion.
As a further improvement on the present invention, the outer wall of described great plastic water pipe has equally distributed convex tendon.This convex tendon can be the vertical or horizontal convex tendon that is arranged in parallel, and also can be crisscross netted convex tendon.Add convex tendon and can improve the intensity of water pipe, strengthen resistivity and the stiffness of pipeline, lay to adapt in the landform of complexity to the soil load.
The present invention compared with prior art has the following advantages: (1) adopts avirulent PE plastics used as water pipe matrix, guarantees quality of water supply; (2) owing to utilize the reinforcing and the resistance to compression effect of good toughness of matrix PE plastics and Framework Of Steel Reinforcement, make the present invention both have good stiffness, have very high intensity again, its compressive strength can reach 50～1000Mpa, can avoid the water leakage phenomenon of breaking and causing because of water pipe effectively; (3) utilize the material behavior of matrix PE plastics, make the present invention have good corrosion resistance, both saved the consumption of metallic material, can improve the life-span of water pipe again greatly; (4) the present invention can realize two connections between the pipe fitting by the threaded coupling of pipe fitting self, need not connect two water pipe pipe fittings with pipe joint, and that utilizes material can make two water pipes when being threaded from close property, need not use sealing material, can reach leak free purpose; (5) plastic material is light, and the pipeline transport carrying is easy, and site operation is convenient; (6) owing to adopt special-purpose slush moulding equipment slush molding to produce, broken through plastic tube and adopted the custom notion of extruding-out process usually, thereby produced the higher large-scale plastic pipe of intensity.
The invention will be further described below in conjunction with drawings and Examples.
