Definitions
- the invention relates to a pressure vessel for receiving at least one fluid medium with a first plastic shell and a first plastic shell at least partially comprehensive second Kunststoffman- tel, wherein the first plastic shell has at least at one end a collar portion comprising an opening for the media supply and removal and wherein the collar portion and the plastic jacket are supported on an intermediate outer support ring which tapers in the direction of a gap opening between said shells.
- EP 1 248 929 B1 discloses a plastic core container reinforced with a fiber-plastic composite as an inner plastic jacket for storing liquid and / or gaseous media under pressure, wherein the core container has one or more connecting pieces in the sheath and / or bottom and / or cylindrical Container part, of which at least one connecting piece for receiving a screw-in cylindrical or conical thread having pressure line feed, such as a valve or a pipe connection is formed.
- connection pin of the plastic core container as a collar part, a cylindrical insert is mounted with a collar end enveloping or circumferential end of the connecting pin, wherein at least two seals are arranged in such a way that at least one seal between Insert and inner surface of the plastic connection pin of the plastic core container and at least one further seal between the insert and the pressure line feed is arranged.
- a generic composite pressure vessel for storing gaseous media under pressure, with a liner made of plastic as inner or first plastic shell known, with two arranged in the neck region neck pieces, and with a Li ner reinforcing winding of a Fiber composite material as a second plastic sheath.
- a clamping ring which can be screwed into this neck piece is provided, which has a threaded section on the outer shell, followed by a thread-free truncated cone-like section, and the annular groove arranged between the female threaded sections of the neckpiece for receiving a sealing ring extends radially in the neck piece and on the outside of the respective neck piece.
- the arrangement provided with at least one radially outwardly over the entire circumference extending bead.
- the wedge-like taper of the outer support ring extends only along the inner circumferential region on the neck piece along a horizontal plane formed by the liner, which in turn opens at a sharp right angle into the collar part which opens and closes the media includes removal.
- the present invention seeks to further improve the known solutions to the effect that in a cost effective manner at a reduced H create a highly reliable pressure vessel is created.
- This object is achieved by a pressure vessel with the features of claim 1 in its entirety.
- the gap opening between the coats is brought to a point where the coats in coaxial arrangement in abutment with each other and that up to this point the wedge-like taper of the outer support ring leads, which is integrally formed or is composed of at least two annular individual segments made of metal, a sealed container or storage arrangement is created, which can be realized with low production costs.
- the pressure vessel according to the invention can be used for a large number of applications, and in that the support is provided via the wedge-like tapered outer support ring up to the outer circumference of the two shells, any relative movements between the plastic sheaths are possible via the outer support ring intercepted and damaging Delaminierratae are avoided in such a way directly between the sensitive plastic materials.
- the mutually facing contour surfaces of the first and second Kunststoffman- tel can be due to the wedge-like leadership of the outer support ring, which leads into the outer peripheral region of the arrangement without sharp deflections and without sudden changes in direction realize, allowing a particularly gentle introduction of force for said plastic shells.
- a particularly favorable introduction of force results when the outer support ring is formed in one piece and then preferably consists of a plastically deformable plastic material, in particular of a polymer material.
- good results can also be achieved if the outer support ring is composed as a rigid support member body of at least two individual segments, for example in the form of single rings, which in turn simplifies the production and thus helps reduce manufacturing costs.
- the outer support ring completely and therefore consists of a single piece of plastic material, it is also excluded that, where appropriate, at sharp-edged transition points, the plastic material of the coats can be damaged by the outer support ring.
- a high rigidity for the container arrangement is achieved, in particular with respect to the collar part of the liner as the inner or first plastic material.
- the outer contour of the outer support ring is also provided with a convex curvature in the direction of the gap opening and its opposite inner contour proceeding from the gap opening in a rectilinear bevel which is at the point of entry of the Collar part opens into a parallel to the longitudinal axis of the container contact surface.
- the pertinent embodiment of the outer support circlip ges with convex curvature on the outer contour and plane-parallel configuration on the inner contour side leads to a particularly favorable introduction of force of the loads of the inner shell in the outer support ring, which is far supported by the outer plastic shell by wrapping on.
- the reproduced in the drawing pressure vessel serves to store liquid or gaseous fluid media, which can be under a pressure of up to several thousand bar. It is provided at both ends with connection openings 10 for the media supply and removal, can be connected to the pressure lines and / or valves not shown or used, which can be dimensioned and configured differently depending on the application for the pressure vessel.
- the pressure vessel has a first plastic shell 12 and a first plastic shell 12, at least partially comprising second plastic shell 14.
- the pertinent first plastic shell 12 is also referred to technical language with plastic core container or liner. It preferably consists of polyamide and is obtained by means of a blow molding process or by rotational sintering. The pertinent production methods are customary, so that no further details are given at this point. will go.
- the addressed liner 12 is reinforced on the outer circumference side by an externally wound fiber winding as a second plastic sheath 14.
- the reinforcing wrap consists of a fiber reinforcement, such as carbon, aramid, gas, boron, Al 2 O 3 fibers or mixtures thereof, which are also referred to as hybrid yarns, which in a basic matrix of thermosets, such as epoxy or phenolic resins or in thermoplastics, for example in the form of PA12, PA6, PP etc. embedded.
- the fiber composite forming the support shell thus contains intersecting fiber strands embedded in synthetic resin which extend substantially in the longitudinal and circumferential directions.
- the fiber composite forming the supporting sheath can additionally or alternatively also comprise fiber strands crossing one another, which can be inclined in the longitudinal and circumferential direction and can be assigned to one another in a mirror-symmetrical inclined manner in an expedient further embodiment of the longitudinal axis of the plastic core container.
- the longitudinal and circumferential forces can thereby be absorbed in an optimal manner by the pressure vessel.
- the possibilities are improved, the ratio of the opening cross-section of a frontal opening, with respect to the inner diameter of the plastic core container to large values of at least 30%, preferably set at least 50%, without resulting in functional impairment.
- the first plastic shell 12 terminates in a cylindrical collar part 16, wherein it would also be conceivable in an unspecified embodiment to close one end of the first plastic shell 12 and to provide only one collar part 16.
- the pressure vessel is formed substantially rotationally symmetrical and extends along its central circumference 18, with coaxial arrangement of its two shells 12, 14 along its longitudinal axis 20.
- the free end of the second plastic sheath 14 opens above the collar portion 16 of the first plastic sheath 12, which has proven to be initiated forces during operation of the container to be favorable.
- the collar part 16 of the first plastic jacket 12 and the second plastic jacket 14 rest on an outer support ring 22 located between them.
- the outer support ring 22 tapers in the direction of a gap opening 24 between the aforementioned casings 12, 14. According to the invention it is provided that said gap opening 24 between the sheaths 12, 14 is brought to a point at which the coats 12, 14 in coaxial arrangement with the longitudinal axis 20 of the memory in abutment with each other, up to this point the Wedge-like taper 26 of the outer support ring 22 leads, which is either integrally formed, which is not shown in detail, or as shown, at least two annular individual segments 28, 30 composed of metal.
- the outer contour 32 of the outer support ring 22 is provided in the direction of the gap opening 24 with a convex curvature and its opposite inner contour 34 extends, starting from the gap opening 24 in a straight bevel, which at the location of Entrance of the collar member 16 opens into a parallel to the longitudinal axis 20 of the container contact surface.
- the curvature of the outer contour 32 increases in the direction of the free end of the second plastic sheath 14.
- the outer support ring 22 consists of metallic individual segments, at least one of the two individual segments 28 or 30 in the peripheral area one Have projection, which opens in a kind of encroachment in a peripheral radial recess of the other single segment.
- the one single segment 30 in the manner of a Anlegekeiles and the other single segment 28 is formed to the free end of the respective collar member 16 in the manner of a parallelogram.
- the collar part 16 of the first shell 12 is supported on the inner circumference side on a further contact surface of an inner support ring 36, which is also formed as a rigid metal ring.
- an inner support ring 36 need not be the same for the two ends of the pressure vessel; However, it is characteristic that the respective inner support ring 36 has an annular groove along an outer circumferential surface, for receiving an O-sealing ring 38, which serves to seal the respective media supply and removal. Further, it is characteristic that the inner support ring 36 is supported in the outer support ring 22 such that a common boundary wall for the media supply and removal is provided.
- the indicated inner support ring 36 is provided in the direction of the interior of the pressure vessel with an abutment whose inclination of the inclination of the slope of the inner contour 34 of the outer support ring 22 is adapted, in particular this corresponds. Furthermore, the outer contour 32 of the outer support ring 22 is provided with an annular recess 40 into which the assignable end of the second plastic jacket 14 opens out under installation.
- the second plastic sheath 14 has at least one additional winding layer 42 which, on the one hand, helps to increase the bursting pressure and, on the other hand, ensures that in case of bursting ge massive internal parts of the pressure vessel or accumulator can not escape bullet-like outward, but are rather retained by the auxiliary winding 42.
- the pertinent additional winding 42 can only be present simply or at multiple discrete intervals from one another.
- Said outer support ring 22 is capable of uniformly distributing stress peaks occurring in the manner of a pressure buffer and introducing them into the two plastic shells 12, 14. Such a Ausbeuien the pressure vessel is effectively avoided.
- outer support ring 22 Since the smallest delaminating relative movements between the mutually facing sides of the plastic shells 12, 14 could occur in the sense of a sliding movement in the coaxial region, it suffices insofar as the support and the separation of the layers or the two shells 12, 14 from each other in the end-side enclosure by the outer support ring 22 to make.
- the indicated cross-sectional wedge shape of the outer support ring 22 is favorable insofar as it effectively counteracts the said relative displacements, for which purpose the different configuration of outer contour 32 to inner contour 34 cooperates.
