Abstract
The utility model relates to a pipe fitting for transporting liquid media of civil tap water and chemical industries, particularly a steel plastic composite pipe fitting. The steel plastic composite pipe fitting comprises a metal pipe fitting, wherein, the interior of which is zincified, and the exterior of which is zincified. A plastic inner lining pipe fitting which is formed by one-step molding is coated on the interior of the metal pipe fitting. The middle part of the plastic inner lining pipe fitting and the inner wall of the metal pipe fitting are tightly connected to form an integral body, and two ends of the integral body form conical interfaces through corresponding mould molding. The utility model has the advantages of corrosion resistance, high intensity, large space, etc.; the interfaces of pipe fittings have good anti-leakage performance, and the inner wall of an inner lining plastic pipe fitting is smooth.
Description
The utility model relates to the pipe fitting of civilian tap water and chemical industry conveying liquid medium, particularly a kind of composite steel-plastic pipe fitting.
At present, civilian water pipe mostly is metal pipe element, and chemical industry is in order to improve antiseptic effect generally at metal pipe element inner-wall spraying anticorrosive coat.Obviously, the former corrosion resistance is poor, and the latter also decreases along with aging its antiseptic property of anticorrosive coat, and its intensity of nontoxic pure plastic pipe spare is difficult to reach usage requirement again.Chinese patent 96242528,98228775 discloses a kind of metallo-plastic composite anti-corrosive pipe and metal composite pipe fitting respectively, though overcome the problem that antiseptic property is poor, intensity is low in varying degrees, but also there are many deficiencys, as: can not guarantee anticorrosion, the antiseepage of pipe joint position, plastic lining pipe fitting wall thickness increases, particularly be difficult to form level and smooth radian, dwindled the pipe fitting internal diameter greatly, reduced the flow of liquid medium at crooked position plastic lining pipe fitting.
The purpose of this utility model is exactly in order to overcome above-mentioned deficiency of the prior art, and provide a kind of anticorrosive, intensity is high, particularly good, the plastic lining pipe fitting inner wall smooth of pipe fitting interface barrier performance, the big composite steel-plastic pipe fitting in space.
The purpose of this utility model is achieved in that it comprises the metal pipe element of interior external galvanized layer, this metal pipe element inside scribbles one-time formed plastic inner lining pipe fitting, this liner pipe fitting intermediate portion and metal pipe element inwall closely are connected to form one, and its two ends constitute cone-shaped interface after by the corresponding mould moulding.
The utility model compared with prior art, because the cone-shaped interface structure has been designed at the pipe fitting two ends, solved the sealing corrosion problem of pipe fitting jointing, adopt mould coating one-shaping technique, guaranteed that pipe fitting inner wall is smooth, the inner space is big, fluid resistance is little, the utility model need not extruder and high compressed steam in manufacture process simultaneously, manufacturing equipment is few, consumption of raw materials is low, greatly reduce product cost, coating is nontoxic, the rubber-like high molecular polymer, in the pipeline connection procedure, can finish sealing automatically, save sealing material, reduce installation cost by pushing its cone-shaped interface.
The explanation of accompanying drawing drawing:
Fig. 1 is the ancient structural representation of pipe of the present utility model.
Fig. 2 is an elbow structure schematic representation of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model embodiment is made up of metal pipe element 1, the plastic inner lining pipe fitting 2 of interior external galvanized layer, this liner pipe fitting 2 adopts mould coating one-shaping technique to be coated on the inwall of this metal pipe element 1, position, intermediate portion and metal pipe element 1 inwall closely are connected to form one, and its two ends are by constituting cone-shaped interface 3 after the corresponding mould moulding.
The utility model also comprises like products such as threeway except that pipe Gu, elbow.
