Definitions
- This invention belongs to the art of gas apparatus, namely to metal-composite high-pressure cylinders used, in particular, in the oxygen breathing apparatus intended for mountain climbers, rescue workers, in portable cryogenic and fire fighting equipment, in gas supply systems, etc.
- Metal-composite high-pressure cylinders produced currently include thin internal hermetic envelope (liner) made of metal, and external pressure-resistant shell made of composite material formed by braids of high-modulus fiber (e.g. carbon fiber) winded over the liner and impregnated by binding substance.
- liner thin internal hermetic envelope
- high-modulus fiber e.g. carbon fiber
- the metal-plastic high-pressure cylinder including stamped-welded hermetic steel liner and external pressure-resistant shell made of composite material.
- the liner includes middle cylinder-shaped part, two bottoms, and has wall thickness 0.5-0.9 mm.
- the bottoms are connected with the middle part by means of welding through spacing rings ensuring the liner's smooth external surface in the place of welding seam.
- a nipple is welded to at least one of the bottoms (see RU 2077682 C1, 20.04.1997 ),
- the liner To manufacture the liner, one is to use steel blank part made of thin rolled sheet.
- the cylinder-shaped part of the liner is to be made of steel-sheet plank part rolled up into a cylinder form and butt-welded by, for instance, electron-beam welding.
- the bottom is to be made by known method of cold stretch from the same rolled sheet. When doing this, since depth of the bottoms is insignificant, that is, as a rule, not more than 0.32 of the external diameter, their thickness upon the stretching is comparable with the thickness of the cylinder-shaped blank part.
- the bottoms are to be welded along their perimeter to the cylinder-shaped part through the spacer rings. This welding is performed, for instance, electron-beam or laser welding. Welding and stamping-welding technologies allow to produce steel liners with rather thin walls and, thereby, to ensure the cylinder's rather low specific consumption of materials.
- the composite high-pressure cylinder including thin-walled metal welded liner and external pressure-resistant shell made of composite material formed by combination of groups of layers of high-modulus and low-modulus fibers of reinforcing materials, which fibers are oriented in spiral and circular directions.
- the cylinder is furnished with rings made of stainless steel and installed at external and internal sides of the liner in the places of connection of the cylinder-shaped shells with the bottoms (see RU 2140602 C1, 27.10.1999 ).
- Disadvantage of the known construction of the cylinder with welded steel liner consists in rather low useful life as regard number of the pressurization cycles due to possibility of the liner destruction in the area of the bottom's welded joint.
- This invention is based on challenge to create metal-plastic high-pressure cylinder allowing to exclude loading of the ring-type welded joint of the cylinder-shaped part with the bottom, and thereby to improve strength of the liner and useful life of the cylinder as regards pressurization cycles number with preservation of low material consumption of the cylinder.
- the metal-composite high-pressure cylinder contains thin-wall welded metal liner and external pressure-resistant shell made of composite material and formed by combination of groups of layers of high-modulus and low-modulus fibers of the reinforcing materials, which fibers are oriented in spiral and circular directions, while in the zone of ring-type welded seam in the liner's envelope there is a ring-type lens-shaped compensator, and while wall structure of the composite pressure-resistant shell of the cylinder includes at least one ring-type bracelet - limiter of axial deformations, which bracelet is installed above the lens-shaped compensator and over all its surface is rigidly connected with the independent groups of continuous reinforcing fibers, while width of this bracelet exceeds width of the compensator, and number of the bracelets-limiters is determined proceeding from the condition of limitation of axial deformation of the compensator, and from resilience of the used material.
- Generatrix surface of the lens-shaped compensator may be executed as a surface composed of two nodoids connected by welded seam.
- Generatrix surface of the lens-shaped compensator may be executed as a surface composed of parts of donut surfaces with their cross-section radiuses equal to 5-7 heights of the lens-shaped compensator.
- Lens-shaped compensator may have at least one peripheral comb located in the welded seam's section.
- Width of the lens-shaped compensator is at least 30-40 thicknesses of the liner envelope.
- Generatrix surface of the lens-shaped compensator may be executed as a cylinder-shaped surface; in this case the compensator is partially inserted into the bracelet - limiter of axial deformations.
- That bracelet - limiter of axial deformations which is installed first from the liner's surface, may have meridional curvature actually coinciding with meridional curvature of the compensator, while the subsequent limiters are located in parallel with the first one within the structure of the composite material with mutual binding by reinforcing fibers of the composite shell.
- Ring-type bracelets - limiters of axial deformations may have various longitudinal and transversal deformation factors.
- Ring-type bracelets - limiters of axial deformations may be made of single-strand high-modulus cord fabric.
- Ring-type bracelets - limiters of axial deformations may be made of combination of high-modulus and low-modulus groups of flexible continuous fibers.
- Group of the high-modulus fibers may be made of metal cord threads, while group of the low-modulus fibers - of the fiberglass threads.
- Group of the high-modulus fibers may be made of the high-modulus carbon fibers, while group of the low-modulus fibers - of the polyamide threads.
- Fig. 1 shows high-pressure cylinder including liner 1 and composite shell 2.
- liner in its turn is composed of cylinder-shape wall 3, bottoms 4 welded to the wall, and nipple 5, which is welded to one of the bottoms 4.
- a lens-shaped compensator In the zone of welded joint of the cylinder-shaped wall and bottom in the liner there is a lens-shaped compensator, which is shown in Fig. 4 Fig. 5 .
- lens-shaped compensator which, due to change of geometry and thrust by the internal pressure, ensures fulfillment of this condition of conformity of deformation of materials of the zone in question.
- Bracelets - limiters of axial deformations may be embodied with use of various constructive schemes.
- bracelet may be embodied as profiled metal lamella plates connected in circular direction by a low-modulus material.
- bracelet may be embodied as a combination of high-modulus and low-modulus fibers oriented in various directions, or with use of the single-strand high-modulus cord fabric. Also, it is possible to combine the aforesaid schemes.
- generatrix of the nodoida (unduloid) is described by ellipse (hyperbola) focus moved along the straight live.
- Such shells possess maximum volume and minimum surface area, while angle of inclination of their tangent to generatrix tends to zero while approaching the place of joint with the cylinder-shaped or any other shell.
- Nodoid and unduloid shells when loaded by internal pressure, possess property of uniform strength, and with respect to strength they have advantage as compared with elliptic and spherical shells. Stresses occurring in nodoid and unduloid shells under this type of loading are significantly lower. Also, it is easy to see that one of the typical properties of the shells in question is that, while approaching the place of joint with the cylinder-shaped wall, this joint is rather smooth and there is almost no bending stress in it, that is edge effects are completely excluded.
- This invention may be used in the oxygen breathing apparatus intended for mountain climbers, rescue workers, in portable cryogenic and fire fighting equipment, in gas supply systems, and in automotive engineering.
