Abstract
The invention discloses a circular pipe special for a rapid pipe connection structure. The circular pipe comprises a circular pipe body divided into at least three layers including a metal thin wall on the outermost layer, a PRC fluid pipe on the innermost layer and a reinforcing layer arranged between the metal thin wall and the PRC fluid pipe. The metal thin wall is a cylinder with the wall thickness of 2-5 mm. The cylinder is formed by conducting welding after an iron sheet curls and wraps the reinforcing layer, and anti-corrosion paint is sprayed on the outer wall of the cylinder. By means of the circular pipe, rapid pipe connection can be achieved.
Description
Technical field
The present invention relates to pipework field, specifically the special pipe of a kind of rapid pipe connecting structure.
Background technique
In existing construction site, for supplying water or the traditional mode of the many employings of other fluid lines, adopting and arranging that steel wire bundle is wound around outward at pipeline, also or employing flange plate carry out butt welding two pipelines be welded, but this mode of operation not only wastes time and energy, need to waste a large amount of cost of labor.And when works progress is very fast, need to move pipeline, now need again the plenty of time carry out pipeline dismounting and re-assembly, the dismounting of flange welding form more bothers, and notably also needs to increase cost and buys new flange plate.
Summary of the invention
The present invention aims to provide the special pipe of a kind of rapid pipe connecting structure, to solve the problem.
For achieving the above object, technological scheme of the present invention is as follows:
The special pipe of a kind of rapid pipe connecting structure, it is characterized in that: comprise pipe body, pipe body is divided at least three layers, comprise outermost metal thin-wall, innermost layer PRC fluid hose, be arranged on back-up coat between metal thin-wall and PRC fluid hose; Described metal thin-wall is the cylinder of 2 ~ 5 millimeters of wall thickness, and cylinder is that the curling back-up coat that is wrapped in of iron sheet welds formation outward afterwards, and at cylinder outer wall rust prevention by applying liquid material erosion paint.
Further, described back-up coat has multiple through hole, and multiple through hole is arranged around circular hollow section center of circle array, is provided with stiffener in through hole.
Beneficial effect of the present invention is:
One, due to the outer wall of pipe is designed to metal thin-wall, it can produce certain deformation under the effect of radial force, makes it more difficultly come off by deformation.The rapid pipe connecting of pipeline can be realized thus completely.
Two, pipe is designed with back-up coat, and back-up coat has multiple through hole, and multiple through hole is arranged around circular hollow section array, is provided with stiffener in through hole.Because the outer wall of pipe is designed to thin-walled, need the intensity being ensured pipe by stiffener, make it not easily bend, intensity is higher.
Three, pipe convenient disassembly of the present invention, owing to being out of shape the tenui-exinous that fastening part is pipe, and under the effect of stiffener, it can not produce bulk deformation, pipe can be cut off by the neat port of sinking mill, when next time connects again, after only the part remained in joint need being taken out, residue pipe can be continued to connect.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the special pipe of rapid pipe connecting structure provided by the invention.
Mark in figure: 6 be metal thin-wall, 7 be stiffener, 8 be back-up coat, 9 for PRC fluid hose.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, the special pipe of a kind of rapid pipe connecting structure, described pipe is divided at least three layers, comprise outermost metal thin-wall 6, innermost layer PRC fluid hose 9, be arranged on back-up coat 8 between metal thin-wall 6 and PRC fluid hose 9.Described back-up coat 8 has multiple through hole, and multiple through hole is arranged around pipe 4 cross section array, is provided with stiffener 7 in through hole.
In use, adopt rapid pipe connecting structure of the present invention, the exterior edge face at joint two ends is provided with outside thread, locking nut 3 size and joint exterior edge face diameter adaptation, and have the internal thread be engaged with the outside thread of joint exterior edge face.Thread forms is the common form that removably connects of mechanical field, and its occlusion ability is strong, difficult drop-off.And in the present invention, because the interior edge face at joint two ends to be designed to the conical surface, and clamping device is also provided with the conical surface towards one end of joint, and the axial angle of the conical surface of joint is greater than the axial angle of the conical surface of clamping device.That is, when locking nut is constantly inwardly screwed, it can promote clamping device constantly towards joint motion, until two conical surfaces start extruding, because the tapering of two conical surfaces is not identical, its contact segment starts as single-point, it can produce radial force in extrusion process, and the axial angle of the conical surface of joint is greater than the design of the axial angle of the conical surface of clamping device, ensure that produced radial force is towards fluid passage, also just creates the clamping force of fastening pipe.Again due to the outer wall of pipe is designed to metal thin-wall, it can produce certain deformation under the effect of radial force, makes it more difficultly come off by deformation.The rapid pipe connecting of pipeline can be realized thus completely.
Pipe is designed with back-up coat 8, and back-up coat 8 has multiple through hole, and multiple through hole is arranged around circular hollow section array, is provided with stiffener 7 in through hole.Because the outer wall of pipe 4 is designed to thin-walled, need the intensity being ensured pipe by stiffener 7, make it not easily bend, intensity is higher.
The pipe convenient disassembly of same invention, owing to being out of shape the tenui-exinous that fastening part is pipe, and under the effect of stiffener 7, it can not produce bulk deformation, pipe can be cut off by the neat port of sinking mill, when next time connects again, after only the part remained in joint need being taken out, residue pipe can be continued to connect.Adopt structure of the present invention simply, easily to realize, effectively can realize rapid pipe connecting.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
