standard Q31/0113000010C014-2018 discloses the structure of a pipe. However, the inner diameter of the pipe fitting is much larger than that of the connected pipeline, so that when the pipeline conveys fluid, the pipe diameter of the pipe fitting is suddenly increased to form pipeline negative pressure, so that the joint of the pipe fitting is damaged, and the fluid conveying is affected.
The invention patent application with the Chinese patent application number of 201810406635.X discloses a continuous fiber reinforced thermoplastic internally concave three-step port high-pressure pipe fitting. Because the pipe end is of a concave three-step structure, the connected pipeline end must form a matched outer convex ring structure, and the outer convex ring is extended into the pipe end for welding. The pipe fitting of this structure has the following drawbacks; the pipe fitting of the structure can reduce diameter when being connected with the pipeline, so that the pipeline is difficult to realize ball passing to remove scale after scaling.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can realize latus rectum, sealed effectual mould glass pipe connection pipe fitting.
In order to achieve the above object, the utility model adopts the following technical scheme:
A plastic-glass tube connecting pipe fitting structurally comprises a pipe section sequentially comprising an inner plastic layer, a reinforcing layer and an outer protective layer, wherein the thickness of the inner plastic layer of the pipe section is larger than the outer diameter of a connected pipeline; two platform rings are arranged on the inner plastic layers at the two ends of the pipe section from inside to outside, and the inner wall surfaces of the two platform rings can be hot-melt adhered to the corresponding platform rings of the connected pipeline.
