Abstract
A kind of ripple U-tube, comprise inside and outside body to form, body two ends are connected with union, described outer wall pipe is helical waveform configuration, inner wall tube is also helical waveform configuration, and inner wall tube screw thread is arranged in outer wall pipe thread, and has additional vulcanised rubber layer between inside and outside wall pipe, described outer wall pipe thread lowest part is provided with reinforcement fin, and described inner wall tube is arranged at intervals with stiffening ring.Substantially increase the intensity of bellows, extend working life.
Description
Technical field
The utility model relates to a kind of mineral hot furnace bellows.
Background technique
It has been generally acknowledged that a key effect of bellows helps to manage interior material opposing external force exactly, and the key that tubular construction resists external force is under normal circumstances exactly pipe thickness, the load that different wall thickness can bear is different, the blocked up consumption of raw materials amount that will inevitably cause of its tube wall is large, simultaneously, tube wall is blocked up easily has influence on again some other the physical property of body as corrosion-resistant and temp. variation resistant performance, and increase bellows wall thickness to the compacting ability of corrugated pipe forming machine and the requirement of formed precision also more and more higher, improve its shaping difficulty.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of ripple U-tube, has inside and outside tube wall, makes to form a cavity between inside and outside two-layer tube wall, to strengthen the entire compression intensity of pipeline, improves weatherability, and reduces consumption of raw materials.
For realizing the utility model object, provide following technological scheme: a kind of ripple U-tube, comprise inside and outside body to form, body two ends are connected with union, it is characterized in that described outer tube is helical waveform configuration, and interior pipe is also helical waveform configuration, Internal Pipe Thread is arranged in external pipe thread, and have additional vulcanised rubber layer between inner and outer pipes, described external pipe thread lowest part is provided with reinforcement fin, and described interior pipe is arranged at intervals with stiffening ring.
As preferably, union comprises nut, expanding ring, taper joint, bellows one end consolidation is inserted in described expanding ring one end, the other end is set to taper bayonet socket, taper joint one end offers cone shape hole, and cone shape hole and taper bayonet socket connect, and taper joint Excircle machining has screw thread, spin with nut, expanding ring and taper joint are connected and fixed.
As preferably, union is plastics.
The utility model beneficial effect: the intensity substantially increasing bellows, extends working life.
