Definitions
- the present invention relates to a pressure tank for storing high and low pressure fluids / gases, in particular LPG or CNG, comprising a hollow body of thermoplastic
- Plastic having at least one opening, which has a circumferential contact surface, one connection piece per opening, which has at least one passage to the interior of the hollow body and which is connected areally with a complementary portion with contact surface, wherein the passage at a lower
- a diffuser which closes the passage in the axial direction and has only substantially in the radial direction facing openings, in the interior of the hollow body, a diffuser enclosing the antistatic wall is present.
- Tanks for holding gases or liquids under low or high pressure e.g. liquefied petroleum gas (LPG) or compressed natural gas (CNG) are known in the art. These tanks are made, among other things, from thermoplastic synthetic material by blow molding, rotational molding or injection molding. In order to increase the pressure resistance, these tanks are provided in a second step with an outer layer of resilient fibers, which are usually embedded in a casting resin, which connects the fibers together and fixes them on the inner plastic layer.
- LPG liquefied petroleum gas
- CNG compressed natural gas
- Such a tank must be provided regardless of the design in any case with at least one fitting into which a pressure-tight coupling part in the form of a valve, hose or pipe end is used to fill the tank or empty.
- the connection between the connecting piece and the coupling part can be made via a latching plug or bayonet lock, but in high-pressure applications, for the most part
- Screw caps with low thread pitch used.
- the inner hollow vessel also referred to as a liner
- a liner may in this case consist of metal, for example aluminum, titanium or steel, or, as mentioned above, be made of a plastic, for example a thermoplastic.
- the latter have the advantage that they are easier to mold and thus can be produced more cheaply and, moreover, their thermal expansion coefficients are better adapted to the matrix of the fiber-reinforced upper layer, which is usually a synthetic resin.
- the disadvantage however, on the one hand a lower compressive strength compared to metallic liners same wall thickness, and a lower temperature resistance. Depending on the application, however, these disadvantages are behind the advantages listed above.
- plastic liners which is of primary importance for the present invention, is their low electrical conductivity and the concomitant tendency to charge statically when filling with a high pressure fluid.
- the fluid exits from the outlet opening of the filling valve, usually metal valve at high speed and travels with electrons, which then on impact on the inner
- Vascular wall are deposited in the area of the impact site. Charge separation can furthermore be caused by the fluid jet impinging on the opposite side of the inner wall at high speed. With hollow bodies or liners made of metal or another conductive material, a charge compensation can take place quickly and easily. To further increase safety both hollow body / liner and valve can be grounded. With plastic fibers, such as thermoplastics, this is not or hardly possible or effective due to the poor electrical conductivity. The consequence is the static charge of the hollow body / liner, which literally can discharge in a flash and unpredictably. If there is still residual oxygen in the interior of the vessel, or if the filled fluid (mixture) is flammable, an explosion can occur. This problem occurs especially when filling an empty, dry pressure tank, since in this case the outflow of forming static charges can only take place poorly and also, if no previous inertization with inert gas has taken place, oxygen is present.
- Inflow velocity of the fluid can be seen from the valve.
- a diffuser at the lower end of the valve. This closes the passage in the axial direction and has only radially oriented openings, so that the inflowing fluid undergoes a directional deflection. As a result, it is braked on the one hand and does not strike the opposite inner wall as a bundled jet, but is split into several partial flows, which initially run horizontally without further measures and then deflected slightly under the influence of gravity almost tangentially onto the Inside wall would meet.
- the abovementioned patent proposes additionally enclosing the diffuser by a cylindrical collar formed as part of the liner / hollow body on the inside of the opening of the hollow body.
- the effluent from the radial openings of the diffuser fluid thus bounces against the collar and is thereby redirected again and strongly braked.
- a disadvantage of this solution is that the extreme deceleration of the fluid through the circulating, closed collar leads to a full running of the remaining space between the diffuser and collar, so builds up a strong back pressure and thus the flow rate is greatly reduced.
- the flow in the intermediate space is very turbulent, so that there is a strong mechanical load on the adjacent components, diffuser, coupling part, fitting and collar, which contribute to a faster aging.
- a much more serious problem of the strong back pressure in the gap between the diffuser and the collar is that it causes the inflowing fluid to be pressed into the seam between the hollow body and the connection piece, which runs at the top of the intermediate space between the diffuser and the collar , which can be compromised especially at high filling pressures and rates, the tightness of the local pressure tank.
- connection pieces Since the wall thicknesses and the dimensional accuracy requirements for the connection pieces differ considerably from the wall thicknesses and the tolerances of the pressure tank, in practice it makes no sense nor is it economical to produce the connection pieces and the tanks in one piece.
- Publication US 2014/0299610 A1 describes a pressure tank with a two-part connecting piece, in which an outer part made of a softer, more adaptable material blocks the connection. to the hollow vessel / liner and the fiber-reinforced layer resting thereon.
- a second part is concentrically embedded, which provides a connection option to a valve or otherwise coupling part in the form of an internal thread. In order to withstand the forces that occur, this is made of a harder material.
- the present invention has the task of developing a connector for pressure tanks made of plastic, which effectively prevents static charging, yet allows high filling rates and guaranteed absolute tightness even at high pressures.
- the invention teaches to provide an antistatic wall surrounding the diffuser which is formed as a part of the fitting or a neck ring or coupling part explained below.
- the tightness during filling is then ensured by the fact that the inevitable interface between the connector and the hollow body / liner advantageously outside of the filling with a high dynamic pressure loaded gap between diffuser and antistatic wall is positioned.
- a reduction in this dynamic pressure is achieved in that the antistatic wall and distributed over its circumference has a plurality of turbulator openings.
- the fluid flowing into the space between the diffuser at the lower end of the passage and the antistatic wall can leave the gap. This relieves the space left between the diffuser and the antistatic wall, thus providing a higher flow rate.
- the size of the turbulator opening is ideally chosen to be somewhat smaller than the beam cross section of the fluid emerging from the diffuser opening, wherein the beam expansion after leaving the diffuser opening is taken into account. This causes the flow to not be completely laminar, reducing charge separation by the flow.
- connection piece of the pressure tank which ultimately serves for the (pressure-) stable connection of an actual coupling part for connection to fluid-carrying hoses or pipes with the hollow body including a possible fiber-reinforced cover layer , which bans the interface between the connector and the hollow body as a weak point from the space between the diffuser and antistatic wall, and achieve by introducing turbulator openings a largely stationary, less turbulent flow in the space, creating the build-up back pressure and thus the material load of this Reduced pressure exposed parts and the flow rate at given filling pressure is increased accordingly.
- the fluid is sprinkler-like atomized when hitting the webs of the antistatic wall or at the latest when exiting the constrictor turbulator openings and leaves the area of the gap as rain of fine and fine droplets that no longer have enough kinetic energy to impact on impact to effect a significant charge stripping on the hollow body inner wall or by friction in the air.
- the anti-static effect of the collar with turbulator openings according to the present invention is thus at least equal to that of a continuous collar, but avoids its massive disadvantages.
- the number of turbulator openings is preferably an integer multiple of the number of radial diffuser openings; in particular, the present invention proposes to provide the same number of turbulator and diffuser openings.
- the antistatic collar preferably has the same symmetries as the diffuser. Both diffuser and antistatic wall, including the turbulator openings, particularly preferably have an n-fold rotational symmetry with n> 2 and one
- the turbulator openings may be shaped differently, for example as round or oval openings in the antistatic wall. Preferably, however, they are designed as elongated recesses or notches starting at the lower edge of the wall and extending over a substantial part of their vertical extension, which have a width in the tangential direction which corresponds approximately to the diameter of the diffuser openings. This is firstly simple to manufacture and secondly results in a flow pattern of the inflowing fluid in the area of the connection piece, which represents a very good balance between turbulence and laminarity and, overall, a quasi-stationary flow.
- the lateral contour of the antistatic wall can be varied, for example, an additional waviness can be impressed on a round base contour, or else a polygonal basic shape is selected.
- Another way to favorably influence the flow conditions when filling the pressure tank is to impart a suitable topography to the inner end face of the diffuser on which the inflowing fluid impinges before exiting through the diffuser openings. This may, for example, be embodied as a convex or conical curvature opposite to the flow direction of the impinging fluid, which leads to improved pressure relief of the connection piece and higher flow rates.
- a mechanism can be integrated in the diffuser, which closes the passage openings at excessively high flow rates.
- an advantageous further development is further to form the antistatic wall as a separate part for attachment to the coupling part. This simplifies maintenance or replacement of the antistatic wall as a heavily loaded and thus wear-prone component.
- this simple serviceability represents a great advantage over designs according to the prior art in which the appropriate collar has an internal, integral component of the hollow body / liner represents.
- the antistatic wall is attached to the coupling part or embodied as part of the fitting or neck ring
- various materials may be used to make it, to affect electrostatic or wear properties.
- a thermoplastic material can also be used.
- the connector of the pressure tank according to the invention is in the most common case in one piece, ie a coupling or connection option for valves, hoses or pipes or the like is integrated into the connector itself. This advantageously avoids additional contact or seams, which could endanger the tightness of the pressure tank.
- the so-called neck ring in an outer connection part made of softer, tougher material, in particular a material similar to the thermoplastic material of the hollow body and meltable by means of this connectable material, concentrically a second part, the so-called neck ring, of hard material, preferably metal, embedded, which has a valve or other coupling part via an internal thread or another coupling option.
- the neck ring is in this case pressed or cast in a complementary recess of the actual connection piece.
- the fitting is molded around the neck ring by casting or spraying.
- the neck ring in particular its contact surface with the actual connection piece, preferably has no circular symmetry, but only an n-fold rotation and particularly preferably one Mirror symmetry with a mirror plane containing the axial direction.
- the contact surface may, for example, have a polygonal, star or wavy outline. As a result, the contact area is increased and allows a better transfer of torque from the neck ring in the connector.
- the present invention proposes to discuss the scope of the
- Neck ring or the circumferential collar or flanges distributes grooves and / or connecting holes, in which the liquid thermoplastic material of the connection piece can flow during manufacture. After cooling, a particularly stable, suitable for torque transmission connection is thus achieved. This is important in order to avoid any frequent changes, i. Screwing in and unscrewing a coupling part, the moments that occur could worsen the bond between the neck ring and actual fitting, which over time could lead to leakage to failure of the fitting.
- the contact surface between the connector and the hollow body is also designed as a non-circularly symmetric torque clutch.
- a polygonal, star or wavy outline is also possible here.
- An alternative is to cast a thermoplastic hollow body around the fitting, whereby a particularly close connection and power transmission is guaranteed, especially when vertical holes are provided in the outer region of the connector into which flow the still liquid material of the hollow body and solidify there can.
- the disadvantage here is that the connector already be present during the production of the hollow body must and can not be changed without destroying it.
- present invention proposes particularly preferred to make the contact surfaces to the one or more fittings in the region of the opening (s) of the hollow body accessible from the outside, so that the connector after completion and curing of the hollow body, inserted and strig meet and / or can be pressed.
- the axial cross-section of the opening should increase monotonically in the outward direction, in such a way that the axial projection of further outward-lying cross-sections further inward.
- the connection part of the connection piece is made of thermoplastic material similar to the hollow body material, the connection can preferably take place by superficial melting of the contact surfaces and compression.
- the diffuser is to the coupling part, i. the valve for connecting a hose or pipe, and in the most general case, the present invention also includes such a configuration.
- the present invention proposes to integrate the diffuser, like the antistatic wall, in the actual connection piece. This has the background that usually in an internal thread of the connector or
- Neck ring screwed coupling part is not always the same angular position relative to the antistatic wall occupies, but this varies at least a little with each screwing.
- the relative position of the diffuser openings to the turbulator openings is also not always the same, which can have a negative effect on the flow of the inflowing fluid.
- This variation of the relative position is advantageously avoided by integration of the diffuser into the fitting.
- the radially oriented diffuser openings are preferably round, oval or polygonal, in particular rectangular.
- connection part neck ring has preferably at the upper end of its passage opening on a centering bevel.
- the neck ring has an axially downwardly projecting collar which is surrounded on its outer sides by the material of the fitting.
- the contact surface to the actual connection piece is further increased.
- the material of the connection piece which lies inwardly from the collar in the radial direction forms a sealing lip whose radial thickness has a decisive influence on the tightness of the pressure tank. Due to the finite vertical dimension of the connection piece, the opening with inserted connection piece projects slightly into the interior of the hollow body.
- the internal tank pressure now acts on both the outer and the inner side of this toroidal emphasis, the inner side is formed depending on the embodiment with or without integrated diffuser through the coupling part or the lower part of the connector.
- the material of the connecting piece and in particular the sealing lip is compressed. Furthermore, by the pressure in the tank, fluid or gas is pressed into the gap between a sealing ring of a coupling part and the sealing lip, deforming both the sealing ring and the sealing lip until an equilibrium of forces between the stresses in the sealing ring, the sealing lip and the internal tank pressure is achieved.
- sealing lip If the radial thickness of the sealing lip is not sufficiently dimensioned, leakage occurs at the connection between the actual connecting piece and the neck ring or connecting piece and coupling part. The latter can be avoided by using a sealing ring between the coupling part and the sealing lip.
- the hardness of this sealing ring should increase with the test pressure of the tank, and thus also the intended maximum filling pressure.
- the present invention therefore proposes to make the radial thickness of the sealing lip larger with the intended test pressure of the pressure tank according to the invention. Specifically, it is proposed to increase the thickness of the sealing lip in proportion to the test pressure. In experiments it was found that a change according to the relationships
- Dmax [mm] 0.01 F [bar] + 3.0 optimal tightness guaranteed.
- P denotes the test pressure
- Dmin the lower and the Dmax the upper limit of the preferred radial sealing lip thickness D.
- connection of such a conical valve is provided by suitable design of the neck ring.
- the design of the connector is addressed without diffuser, since conical valves are already equipped in the most common design with a diffuser, but without anti-static wall.
- the hollow body of the pressure tank according to the invention In order to withstand very high test pressures of several hundred to over one thousand bar, the hollow body of the pressure tank according to the invention must be enclosed by a fiber-reinforced cover layer. This is all the more necessary, since the thermoplastic materials proposed for the hollow body could withstand only a few bar up to a maximum of about ten bar on their own with typical wall thicknesses in the millimeter range.
- the fibers used in this layer can be synthetic fibers, such as Glass, carbon, aramid, dyneema or other synthetic fibers, or natural fibers. Various fiber species can also be used in combination to optimize costs at a desired strength.
- the matrix in which these fibers are embedded consists of either thermally or optically crosslinked
- (Art) resins such as epoxy resin, or of a plastic, for example polyethylene, which is applied in liquid form to the fiber-wound hollow body and then allowed to cool.
- the outer side of the hollow body before the winding of the fibers and the application of the surrounding matrix is subjected to a surface treatment in which the roughness increases and thus a better connection between matrix layer and liner / hollow body is achieved.

- Diffuser 22 serves to slow down and redirect a fluid flowing in under high pressure, for which purpose it closes openings 21 in the axial direction and only has radially oriented outlet openings 221.
- the radially flowing after passing through diffuser openings 221 fluid hits with respect to a theoretical flow velocity without diffuser reduced speed on the diffuser 22 enclosing antistatic wall 27, which is formed as turbulator openings 28, here formed as elongated notches, interrupted cylinder collar.
- Antistatic wall 27 is an axially directed projection of the outer connector 20 and thus constitutes an integral part of the connecting part 20.
- the diffuser 2 are mirror-symmetrical and rotationally symmetrical, where he 6 having no rotational symmetry. The same applies to antistatic wall 27.
- the tightness of the pressure tank according to the invention shown here both in the filling and in the pressure-filled state is further advantageous by dimensioning the radial thickness of the sealing lip 24, which extends between a down in the axial direction from the neck ring 23, starting neck collar 231 and sealing ring 31 of the Coupling part 3 extends, proportionally increasing with the intended test pressure, ie Maximum pressure of the tank guaranteed.
- FIG. 1a shows an enlarged section of the lower half of connecting piece 2 and of the lower end of passage 21, respectively.
- the difference between the height HT of the internal thread 25 and the distance DO between the lower edge of internal thread 25 and sealing ring 31 is selected according to the relationship HT-DO ⁇ 0.5 TP, where TP stands for the thread pitch of the internal thread 25.
