Definitions

  • the invention relates to a pressure can with a container, the container opening of which is closed by a valve plate which has an opening for receiving the valve body of a metering valve.
  • Pressure cans are primarily known as spray cans, by means of which flowable or dustable media can be dispensed in doses.
  • the pressurized cans have ge grill ⁇ Lich * on a metallic container whose tel arranged in Schei ⁇ opening is completed by a metallic tilteller VEN; this is designed as a flat or with a recessed lid and has a centrally arranged opening for receiving a metering valve.
  • the metering valve can be designed in various ways, for example as a tilting valve, in which a side force is exerted on the valve stem of the metering valve for metering the medium, by means of which the valve seat on the underside of an elastically deformable and flexible valve body is released and so that the medium can emerge from the can (US Pat. No.
  • metering valves are designed with a hollow valve stem, which is axially displaceably mounted in the valve body.
  • the valve stem itself is under the action of a compression spring which presses the valve stem onto the valve seat arranged in the valve body.
  • the compression spring exerts a relatively large force on the valve stem, so that the valves can also be used for high propellant pressures.
  • such valves cannot be used in particular in the case of viscous media or also in the case of moisture-curing materials, for example polyurethane material.
  • the moisture-curing material hardens in the area of the spring passages, as a result of which the function of the spring can be impaired or even completely canceled.
  • the known tilt valves have the disadvantage that an immersion tube cannot be attached to them, or only with considerable effort. This means that with viscous media - and these are used in large numbers today, e.g. one-component polyurethanes for the production of foams - the pressure cans must be emptied with the valve downwards, which ensures clean processing, e.g. when foaming gaps between windows and masonry is made considerably more difficult.
  • the invention is therefore based on the object, a pressure can of the type described.
  • Type in such a way that the pressure cell, regardless of the type of metering valve it is equipped with, is in an upright position, i.e. with the metering valve upwards, can be used and. thus ensuring simple and clean processing of the can medium.
  • the possible use of the pressure cell is to be expanded in such a way that the metering capacity is increased and processing is possible in any position
  • This object is achieved according to the invention in that a hollow connecting part surrounding the valve body of the valve is arranged on the valve plate. This ensures that no additional parts are required for fastening the connecting part.
  • FIG. 1 shows a section through a partially illustrated pressure cell with a valve plate that closes the apex opening and carries a metering valve
  • Fig. 4 shows a section through the valve plate of a pressure can with another
  • FIG. 6 shows a section through a further embodiment of the connecting part with a cylinder with piston and attached to it 7 shows a section through a further embodiment of the connection part as a bag.
  • the head part 1 shows the head part 1 of a pressure can 2.
  • the head part 1 has a reinforced edge 3, on which a valve plate 4 is attached.
  • Both the container and the valve plate 4 are mostly designed as thin-walled, metallic parts.
  • the valve plate 4 has a teel edge 5 with which the valve plate 4 is fastened on the edge of the apex part 1.
  • a seal is usually provided. This seal is achieved in the embodiment according to FIG. 1 by a connecting part 15, the upper edge of which extends between the edge 3 and the plate edge 5 and is provided with a curvature corresponding to the curvature of the edge 3 or the plate edge 5 .
  • the connecting part 15 itself can be shaped in various ways. It can, see Fig. 2, be designed as a cylindrical hollow body 15 and extend with its lower edge 13 up to the bottom of the container, not shown.
  • the lower edge 13 does not need to run perpendicular to the axis of the connecting part 15, but can also be designed obliquely to this, see the edge 13 ′ shown in broken lines in FIG. 2.
  • the metering valve 20 ' is designed as a tilting valve and has a portion extending through the opening 16 the valve body 21 of the' 5 an internal valve seat body 22 and a
  • a valve stem 24 with a longitudinal channel 25 is arranged in the valve body 21.
  • the valve stem 24 has a collar 26 on which the spring and guide sleeve 23 of the valve body 21 is supported.
  • the Ventil ⁇ shaft 24 an inner end flange, whose via the valve stem 2 'protruding outer edge' with the valve seat body 22 takes over the sealing of the valve.
  • Outlet openings 28 are arranged in the valve stem 24 directly on the end flange 27.
  • the end flange 27 is lifted off on one side from the valve seat body 22, as a result of which the can contents can exit through the outlet openings 28 into the longitudinal channel 25 and from there into the open.
  • another valve for example a valve which can be actuated in the axial direction of the valve stem 25, can also be used.
  • the design of the metering valve 20 has no influence on the present invention.
  • the connecting part 15 can be designed as a tubular part. It can also have openings 35 in its jacket at different heights, the diameter of which can be adapted to the respective can contents.
  • the arrangement of the openings 35 ensures that there is sufficient dosing capacity when dosing foams.
  • Foams for example polyurethane foams, are subject to considerable damage when flowing through the connecting part 15 Pressure loss.
  • the openings 35 are provided, which also allow the foam to be processed in any position of the pressure cell 2.
  • the cross section of the connecting part 15 need not be circular, but can also be provided with corners and beads, as shown in FIG. 3.
  • the angular or polygonal cross section of the connecting part 15 improves the stability of the connecting part 15.
  • the diameter of the connecting part 15 can be kept as desired and can be adapted to the respective requirements or the can contents. It is essential that the connecting part 15 can be installed in a very simple manner.
  • the pressure can is filled with the propellant gas via the metering valve 20.
  • the valve plate 4 shows a further head part 1 of a pressure cell 2.
  • the valve plate 4 On the edge 3 of the pressure cell 2, as in FIG. 1, the valve plate 4 is fastened; it has a plate edge 5 with which the valve plate 4 is fastened on the edge 3 of the pressure cell 2.
  • a nozzle 6 and a shoulder 7 adjoin the plate edge 5.
  • an extension part 10 Connected to the shoulder 7 is an extension part 10 in the form of a pipe socket, the diameter of which is smaller than the diameter of the socket 6.
  • the extension part 10 has an edge bead 11 which merges into an inwardly directed flange 12.
  • the extension part 10 is not exactly cylindrical, but has a larger one in the region of the edge bead 11 Diameter on than in the area of the shoulder 7; this ensures better attachment of the connecting part 15.
  • the subsequent edge bead 11 at the flange 12 has an opening 16 and is used to attach a valve 20, which is formed as a 'tilt valve better ⁇ as shown in Fig. 1 and will therefore not be described.

  • a partially illustrated riser pipe 19 is attached to the nozzle 17 in a suitable manner, e.g. fixed by gluing. In this way, you can easily use a pressure can with a tilt valve in an upright position. This allows the pressure can to be guided better and makes processing of the metered material easier.
  • the connecting part 15 can also be designed in a different way.
  • the arrangement of the extension part 10 on the valve plate 4 allows extensive freedom of movement; only the connecting part 15 has to be designed accordingly and fastened to the extension part 10.
  • the connecting part 15 is provided with two connecting pieces 17, each with an opening 18. Bags (not shown) can be connected to these two nozzles 17, for example, in order to mix two components that have to be stored separately when metering.
  • the connecting part 15 has a larger socket 17, to which a dimensionally stable tube 30 is fastened.
  • a piston 31 serves as a closure which, when metered by the propellant, presses the product filled inside the tube 30 through the valve 20.
  • a bag 32 e.g. made of polyethylene.
  • the product filled in the bag 32 is pressed out of the valve 20 without contact with the propellant. It would of course also be possible to attach the bag 32 directly to the extension part 10, e.g. by gluing.
  • extension part 10 with a connecting part 15, which is designed either as an intermediate body for further parts or as a closed body, ensures that the pressure cell 2 is in exactly the same way, i.e. before attaching the valve plate 4 to the container (clinching), with which propellant can be provided as if it were a pressure can with a simple tilt valve.
  • the nozzle 17 can be made so long that, despite any tolerances of the can parts, the riser pipe 19 cannot detach from the nozzle 17.
