Definitions

  • the invention relates to a pressure vessel according to the preamble of claim 1.
  • pressure vessels are also known, for example, from US-A-3992003, in which several components are accommodated in separate sub-vessels and are only used shortly before processing of an adapter head and then discharged as a mixture.
  • the disadvantage of this design is that, on the one hand, a uniform mixture of components and, on the other hand, a constant mixing ratio are not guaranteed.
  • outlet valves of the individual partial containers should be arranged in the funnel, whereby standardized valves should be usable.
  • this is practically impossible with the arched funnels commonly used today.
  • EP-A-0249100 which was filed at the same time.
  • the invention is based on the object of designing a pressure vessel of the type described at the outset in such a way that high pressure can be applied to maintain a constant mixing ratio, standardized outlet valves being used for the closure of the sub-vessels and the mixing ratio of the components being simpler Can be adjusted to the required ratio.
  • the pressure vessel 1 shown in Fig. 1 is made of a e.g. made of tinplate, aluminum, an aluminum alloy, plastic or a composite material metal-plastic, produced container frame 2, an inwardly curved bottom 3 and a funnel 4.
  • two sub-containers 5, 6 are accommodated, which are made of plastic and are supported with their base parts 7, 8 on a piston 9.
  • the piston 9 is acted upon by a propellant gas filling which fills the space between the piston 9 and the bottom 3 and by a closure 10, e.g. a pressed plug or a one-way valve, can be filled.
  • the funnel 4 is composed of two part funnels, an inner part funnel 13 on the one hand and an outer part funnel 14 on the other hand.
  • the inside funnel 13 has a diameter that corresponds approximately to the inside diameter of the cylindrical container frame 2 and is designed with a greater wall thickness than the outside funnel 14.
  • the partial funnel 14 has a larger diameter than the inner partial funnel 13 and in the circumferential area a groove 15, against which the inner partial funnel 13 abuts from the inside.
  • the outside partial funnel 14 has a flanging section 16, by means of which the flanging is produced between the frame edge of the container frame 2 and the funnel 4. Because only the one In the present case, the outside partial hopper 14 is used for this flanging, it can be produced reliably and with less effort.
  • the openings 11, 12 are provided with an edge 17 which is approximately perpendicular to the funnel plane and faces away from the inner partial funnel 13. It is essential that the edge 17 is formed from both partial funnels 13, 14, whereby its wall thickness represents the sum of the wall thicknesses of the two partial funnels 13, 14 and does not require any additional flanging.
  • the edge 17 serves to receive a valve plate 18, the edge curvature 21 of which comprises the unrolled edge 17 formed from the partial funnels 13, 14 and is crimped with it. This creates a reliable connection between the valve plate 18 and the funnel 4.
  • the partial containers 5, 6 designed as folding bags have a neck-shaped bag neck 22, 23 which is open at the top and which has a reinforcing bead 24, see FIGS. 3 and 4.
  • the edge of the bag neck 22, 23 is underneath the curvature 21 of the valve plate 18 via the Edge 17 of the funnel 4 placed and then crimped with the valve plate 18.
  • the bag neck 22, 23 thus forms a reliable seal between the funnel 4 and the valve plate 18.
  • Each valve plate 18 carries a valve 19, 20, with which a complete closure of each partial container 5, 6 is ensured.
  • Both the valve plate 18 and the valves 19, 20 are standardized elements which, thanks to the special design of the funnel 4, can be used without modification.
  • valves 19, 20 consist of a tubular valve tappet 25 and an elastically deformable valve body 26 which is latched into an opening 27 in the bottom 28 of the valve plate 18.
  • the construction and function of the valves 19, 20 is known, see for example US Pat. No. 3 662 926.
  • the essentially flat funnel 4 allows the arrangement of two or more valves 19, 20 depending on the number of partial containers 5, 6.
  • the funnel 4 can be used even for high pressures due to the use of partial funnels 13, 14 without the Wall thicknesses of the partial funnels 13, 14 must be chosen to be excessively strong.
  • the partial funnels 13, 14 form a stable whole, since they are connected to one another in a suitable manner, for example by spot welding or gluing.
  • a cavity 29 is formed between the two partial funnels 13, 14 and is provided with passages 30, 31.
  • the cavity 29 can be designed as a ventilation device, see FIGS. 5 and 6, in that an elastically resilient tongue 32 is inserted into the cavity 29.
  • the tongue 32 lies against the passage 31 of the outside funnel 14 and is thus in the closed position in which the interior of the pressure vessel 1 is closed in a pressure-tight manner. If the tongue 32 is removed from the passage 31 by depressing a pin 33 and brought into the open position, see FIG. 6, one is formed Connection of the interior of the pressure vessel 1 with the outside air. This venting operation is required in each case when components are removed from the partial containers 5, 6 so that the piston 9 acted upon by the propellant gas filling can carry out its lifting movement for emptying the partial containers 5, 6.
  • an adapter head 40 is provided, which is plugged onto the valves 19, 20 of the partial containers 5, 6 and has two supply lines 41, 42, which open into a connecting piece 43.
  • a mixing tube (not shown) is screwed into the connecting piece 43, in which the components are mixed and brought to the processing point.
  • the adapter head 40 is made in several parts. It is composed of a base body 44 and a head piece 45 with the connecting piece 43.
  • the head piece 45 is screwed onto the base body 44 by means of a union nut 46, which also has an end plate 49.
  • a relatively soft, conical sealing sleeve 47 is inserted into the base body 44 for each supply line 41, 42. Furthermore, a metering sleeve 48 is provided at the transition between the base body 44 and the head piece 45 in the feed lines 41, 42. The mixing ratio of the components can be adjusted with the dosing sleeves 48, which is why they can be replaced after removing the head piece 45.
  • the piston 9 is composed of two parts, a sealing part 50 on the one hand and a cup-shaped piston part 51 on the other hand.
  • the two parts 50, 51 consist of a plastic and are, e.g. bonded together by gluing or welding.
  • the sealing part 50 has a recess 52 on the part-container side, into which the bottoms 28 of the part-containers 5, 6 project and are supported by ribs 53, see FIGS. 10 and 12.
  • a projection 54 is provided, in its recess on the rear a projection 56 of the bottom 57 of the piston part 51 protrudes and is centered.
  • a further centering of the piston part 51 is achieved by means of ribs 58 which delimit a depression 59 opposite the depression 52.
  • the two depressions 52, 59 are surrounded by a cylindrical wall 60 which has a number of annular grooves 61 for receiving sealing rings 62.
  • three sealing rings 62 are provided, but their number can be changed as needed.
  • the piston part 51 is a relatively thin-walled plastic part, the piston skirt 63 of which has a conical sealing and guide lip 64 on its free edge.
  • the adapter head 40 is depressed, as a result of which the valves 19, 20 are opened simultaneously and uniformly.
  • the ratio of the components can be determined by the metering sleeves 48.
  • the ratio of the discharged components can also be achieved by sub-containers 5, 6 with different cross-sections.
  • the sub-containers 5, 6 have the same cross section.
  • the ratio of the components can be changed to a certain extent by the dosing sleeves 48.
  • the sub-containers 5, 6 must also have different cross-sections. For example, one cross section can then be circular and the other cross section can be kidney shaped. With these options, however, the mixture ratio can be varied within wide limits and the viscosity of the components can be adjusted.
  • the actuating devices 85, 86 shown in FIGS. 8 and 9 serve to depress the adapter head 40 when the components are removed.
  • Both actuating devices have a fastening sleeve 87 which is attached to the funnel 4 of the pressure container 1 and engages in the flanging of the funnel.
  • an angle lever 88 is pivotably mounted at the end of one lever arm 89, while the other lever arm 90 extends along the pressure vessel 1 and is used for the manual actuation of the angle lever 88.
  • One lever arm 89 extends through a passage 91 of the adapter head 40.
  • the adapter head 40 By depressing the angle lever 88, the adapter head 40 is pressed down, as a result of which the valves 19, 20 are opened. There are also two pins on the funnel side of the end plate 49 of the adapter head 40 33, see FIGS. 5 and 6, which bring the tongues 32 into the open position when the adapter head 40 is pressed down, as a result of which the interior of the pressure container 1 is vented. 8 and 9, the adapter head 40 is not shown, but rather because of its better overview only because of its funnel or valve-side end plate 92.
  • the actuating device 86 has a rotating sleeve 93 which is screwed to the fastening sleeve 87.
  • a control ring 94 is also attached to the rotary sleeve 93, which is destroyed when the rotary sleeve 93 is rotated to open the valves 19, 20 and thus indicates that the pressure vessel 1 has already been used.
  • the pressure vessel 1 described can be used for any components. Not only two, but also three and possibly also more components can be accommodated in the pressure vessel 1, the funnel surface making it possible to arrange the valves with the aid of standardized valve disks.
  • the strength of the funnel 4 can be adapted to the respective requirements by choosing the wall thicknesses of the partial funnels 13, 14.
  • the partial funnels are expediently made of different materials, as is the container frame and the container base 3. Suitable materials are metals, for example tinplate, aluminum and its alloys, plastics with and without reinforcement or composite materials metal-plastic.
  • the parts of the adapter 40 are preferably made of plastic or metal, while the actuating devices 85, 86 consist of plastic or metal.
  • the dosage ratio adapt within wide limits by means of differently sized partial containers 5, 6 and dosing sleeves 48.
