Abstract
The utility model relates to a pipe expansion bend, which is composed of a flange plate, an inner sleeve pipe, an outer sleeve pipe, a telescopic box, a larger stop block, a small stop block and a middle-section sleeve pipe. The utility model solves the heat expansion and cold contraction of the pipeline, and doesn't leak; the installation and the transportation are convenient; a telescopic well can be exempted. The expansion bend has simple and reasonable structure and doesn't have wearing parts, the production cost is low, the special equipment and the complex technology can not be required when making; the use is safe; the utility model is the best product in the field.
Description
The utility model relates to a kind of pipeline extension device, particularly a kind of expand with heat and contract with cold expansion bend of usefulness of pipeline of regulating.
Usually regulating the expand with heat and contract with cold expansion bend of usefulness of pipeline has the bushing type expansion bend, artificial square expansion bend and the wave mode formula expansion bend of simmering system, and these expansion bend operational safeties are poor, and the seepage phenomenon is more serious, must build the ditch assembling, assembly fee expenses of labour power, and cost is higher.My China Patent No. 90200865.X provides the plate-and-box type can spacing pipeline extension device, through applying in the past few years, perfect in practice this patented technology is improved the 90200865.X patent by practical effect and production equipment and process conditions.
The utility model is achieved in that an end of flange plate and outer sleeve links together, and an end of the other end of outer sleeve and adjust case links together, and the other end of adjust case and middle joint sleeve pipe link together; Each fixes a big limiting stopper on the internal diameter tube wall of outer sleeve; Fixing inner sleeve on the internal diameter tube wall of middle joint sleeve pipe is fixed two little limiting stoppers on the inner sleeve.
Owing to realized technique scheme, therefore have and make simply than prior art, flexible reliable, the phase mutual friction reduces resistance.
The concrete structure of the utility model is provided by following drawings and Examples:
Figure of description is the utility model structure cutaway view.
Describe in detail according to an embodiment who the utility model proposes with reference to the accompanying drawings.
Shown in the accompanying drawing: an end of flange plate (7) connects with pipeline, the other end and outer sleeve (6) link, outer sleeve (6) links with adjust case (1), the other end of adjust case (1) and middle joint sleeve pipe (5) link, the inwall of middle joint sleeve pipe (5) is fixed an inner sleeve (4), two limiting stoppers (3) are arranged on the inner sleeve (4), and each fixes a big limiting stopper on the internal diameter tube wall of outer sleeve (6).
The utility model is installed in the centre of pipeline, parallel installation, support is established on both sides, with U type card on the pipeline card on expansion bend both sides, but needn't be stuck, can allow pipeline slide, can compensate like this and expand with heat and contract with cold, can prevent that again local compression from increasing the effect that damages miscellaneous part and precipitated impurities.
Claims (3)
1, a kind of pipeline extension device, comprise two flange plate (7), it is characterized in that two flange plate (7) and an end of two outer sleeves (6) link together, one end of the other end of outer sleeve (6) and adjust case (1) links together, and the other end of adjust case (1) and middle joint sleeve pipe (5) link together.
2, pipeline extension device according to claim 1 is characterized in that each fixes a big limiting stopper (2) on the internal diameter tube wall of two outer sleeves (6).
