Abstract
The invention provides a connection structure for steel-mesh polyethylene pipes. The connection structure comprises parts such as flange cylinders, flange pieces, flange stop plates, a rubber gasket, nuts and bolts. Pressure-containing members are made of metal materials with surfaces galvanized, and connected in buckled and pressed manners. The technology is relatively simple, sealing effect is good, pressure-containing capacity is high, cost is low by adopting the connection structure to connect underground pipelines, technology reproducibility is good, and the connection structure is widely applicable to connection of steel-mesh polyethylene pipes of all types of section steel.
Description
Technical field
The present invention relates to seal for pipe joints interconnection technique field, relate in particular to a kind of linkage structure be tightly connected for the steel wire polyethylene compound pipe.
Background technique
The steel wire polyethylene compound pipe is a kind of Novel composite pipe, and it has the advantages such as intensity is high, corrosion-resistant, expansion coefficient is little, is widely used at present the underground conveying of liquid substance.Due to characteristics such as such tubing ubiquity overpressure in application process are high, the external environment oxidability is strong, so the technology of being tightly connected of such pipeline seems particularly important.
In prior art, the mainly mode of being tightly connected for the steel wire polyethylene compound pipe is heat-melting butt-joint and electric melting connection, but all there is open defect, the bearing capacity of its joint and the bearing capacity of tubing do not mate, can't bear higher working pressure, in addition, above-mentioned two kinds of connecting means need special device and special messenger to carry out attended operation, the bearing capacity of its jointing and operator's gimmick have much relations, so the reproducibility of technological effect is poor.
In prior art, the mode of taking flange to connect for the steel wire polyethylene compound pipe rarely has report, and, because technological requirement is higher, causes this Placement to be had relatively high expectations to associated components.Therefore be necessary for the technical characterstic of steel wire polyethylene compound pipe develop a kind of material more reliable, connect the better pipeline jointing construction of effect.
Summary of the invention
The present invention is intended to the technological deficiency for prior art, provide a kind of material more reliable, connect the better pipeline jointing construction that is applicable to the steel wire polyethylene compound pipe of effect.
For realizing above technical purpose, the present invention by the following technical solutions:
A kind of pipeline jointing construction, comprise flange cylinder, flange plate sheet, flange baffle plate, rubber gasket, nut, bolt, wherein flange cylinder is placed in the pipeline outside, the flange plate sheet inner circle is fixedly connected with it with the flange cylinder cylindrical, the flange baffle plate is round, the flange baffle plate keeps the identical flange plate sheet surface that is fixedly connected on, the center of circle with flange plate sheet, and rubber gasket is sandwiched in the middle outer of two flange baffle plates to it, and nut is fixed with bolt tightening in the middle of two flange plate sheets.In said structure, flange cylinder, flange plate sheet, flange baffle number are 2, all are symmetry status and settle; Nut and bolt quantity are 8; Flange cylinder, flange plate sheet, flange baffle plate material are metal, and outer surface is zinc-plated.This linkage structure is particularly useful for the connection of steel wire polyethylene compound pipe.
The present invention implements to connect by flange arrangement, and its technique is relatively simple, good sealing effect, and parts adopt metal material can strengthen the bearing capacity of linkage structure.

Embodiment
Get two, the zinc-plated metal flange cylinder of outer surface that forming processes is good, two of the zinc-plated metal flange discs of outer surface, two, the zinc-plated metal flange baffle plate of outer surface, one of rubber gasket, 8, nut, 8, bolt is stand-by, two flange cylinders are placed in respectively to the right port outside of pipeline to be connected, again two flange plate sheet inner circles are fixedly connected with it respectively with two flange cylinder cylindricals, again two flange baffle plates and two flange plate sheets are kept to the center of circle is identical is fixedly connected on respectively two flange plate sheet surfaces, in the middle of rubber gasket being sandwiched in to two flange baffle plates, outer is to it again, 8 nuts are uniformly distributed in to the flange plate sheet surface and run through two flange plate sheets, with 8 bolts, tighten respectively fixing again.
Above the embodiment of the present invention is had been described in detail, but described content is only preferred embodiment of the present invention, not in order to limit the present invention.All any modifications of making in application range of the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
