Abstract
The utility model discloses a can improve wave type welding bellows of stress state comprises continuous tube coupling, its characterized in that the ripple section of tube coupling is formed by the connection of wave curved surface diaphragm. The elastic shrinkage of the structure is very good through experimental tests, the stress state of the corrugated pipe structure can be greatly improved, the application prospect is good, and particularly the reliability of the device can be greatly improved when the corrugated pipe structure is applied to nuclear equipment.
Description
Technical field
The utility model relates to machinery and physics, a kind of specifically wave-like type welded bellows that improves stress phase
Background technique
Along with science and technology development, the application of welded bellows is extensive day by day, not only is used for the nuclear energy field, and can be used on Aero-Space and the large-scale civil equipment.Its predominant use is various sealings and the energy transfer element that not only can be used as cryogenic system, and can be used as the Detecting element of control mechanism, transmitter or regulator, and the measuring cell of temperature, pressure and liquid level, simultaneously can also be as absorbing small deformation, reduce the elastic element that structural stress is concentrated, as be used in the welded bellows on the Tokamak nuclear fusion vacuum chamber window neck-pipe.But the diaphragm of the welded bellows that uses is broken line type at present, is by the broken-line type diaphragm, and a slice a slice is welded; be difficult to bear flexural stress; the stress concentration phenomenon occurs through regular meeting in actual use, the part is easy to exceed the allowable stress of structural material, and fatigue ruption takes place.
The model utility content
The purpose of this utility model provides a kind of wave-like type welded bellows that improves stress phase, is that a slice a slice is welded by waveform curved surface diaphragm, and is flexible relatively good, can bear bigger flexural stress.The technical solution of the utility model is as follows:
A kind of wave-like type welded bellows that improves stress phase is made up of continuous tube coupling, it is characterized in that the bellows segment of described tube coupling is formed by connecting by waveform curved surface diaphragm.
Described bellows is characterized in that material is a metal.
Effect of the present utility model
The utility model proposes a kind of diaphragm is wave curved welded bellows, and this structure has been applied to China " 95 " specific national scientific development project---on the horizontal neck tube of HT-7U superconducting Tokamak nuclear fusion vacuum chamber.Elastic shrinkage through this structure of experiment test is very good, can improve the bellows structure stress phase greatly, has good application prospects, particularly is applied on the nuclear armament, can improve the reliability of device greatly.
Description of drawings
Fig. 1 is a prior art welded bellows structural representation.
Fig. 2 the utility model welded bellows structural representation.
Embodiment
Referring to Fig. 1 is prior art ripple administration structure (expression is half of bellows among the figure, and second half is symmetry with it), and its bellows segment is that broken-line type convolution diaphragm 1 is formed by connecting.
Referring to Fig. 2 (be half of the utility model bellows, second half is symmetry with it), the utility model can improve the wave-like type welded bellows of stress phase, is made up of continuous tube coupling 2, and the bellows segment of tube coupling 2 is formed by connecting by waveform curved surface diaphragm 3.Waveform curved surface diaphragm 3 materials are metal.This structure has been applied to China " 95 " specific national scientific development project---on the horizontal neck tube of HT-7U superconducting Tokamak nuclear fusion vacuum chamber.
The described material that improves the wave-like type welded bellows of stress phase is the 316L stainless steel material.
Claims (2)
1, a kind of wave-like type welded bellows that improves stress phase is made up of continuous tube coupling, it is characterized in that the bellows segment of described tube coupling is formed by connecting by waveform curved surface diaphragm.
2, bellows according to claim 1 is characterized in that material is a metal.
