Definitions

  • the invention relates to a two-component pressure cell with a valve having a valve body and a valve tube, an outer container for a first component and propellant and an inner container sealed against the outer container for the second component and possibly further propellant, in which outer container below the valve plate is a tubular element extending in the direction of the can bottom, the inner container is detachably arranged at the lower end of the tubular element and is hermetically sealed against the inside of the tubular element by a sealing element, the valve tube on the valve body in the outer container projecting part has an engagement element which engages in a complementarily designed receptacle of an element, the downward movement of which causes the inner container to be blown off, so that the inner container, actuated by the valve, opens into the outer container from the outside can be et.
  • Such a two-component pressure cell is particularly suitable for the production of two-component foams, for example polyurethane foams.
  • a further inner pressure container with the second component is generally introduced in an outer pressure container with the prepolymer, the contents of which, after being triggered, are emptied into the prepolymer from the outside and mixed with it. The resulting one reactive mixture is then expelled with foaming agent present in the pressure vessel.
  • Known 2K pressure cans contain the inner container for the second component, for example in the area immediately above the can bottom.
  • the trigger with which the two components are brought together is arranged on the bottom of the can and is actuated by pushing in or twisting. Examples include the German utility model 82 27 228 and DE-A-30 22 389 and DE-A-33 22 811.
  • a disadvantage of these previously known solutions with a trigger mechanism in the base area is that, apart from the complex valve construction in the dome area of the pressure cell, a second, complex area on the bottom of the box is necessary. On the one hand, this increases the manufacturing effort and thus the manufacturing costs and, on the other hand, creates a second area of the pressure cell which is sensitive to external influences and which has to be protected against external forces by suitable measures, such as the attachment of seals, protective caps, fuses .
  • the valve for filling the pressure can with propellant gas cannot be arranged in the center of the can base with little effort, as is customary in some cases.
  • an inner pressure vessel arranged in this way under the valve unit is opened and emptied into the outer pressure vessel in such a way that, by moving the valve downward, a rod which is arranged inside the inner pressure vessel and reaches to the bottom thereof is brought to the bottom in this way acts that the seal between the inner container and holder in the dome of the pressure cell is released.
  • the disadvantage here is that the contents of the inner container can also be activated by accidental pressure or impact, so that the can components are prematurely mixed.
  • actuation of the valve before the two components are mixed cannot be ruled out, which leads to premature emptying of the inner container and renders the entire contents of the pressure container unusable because the quantities of the two components are no longer coordinated.
  • EP-A-0 528 190 a two-component pressure cell with an outer container for a first component and propellant and an inner container closed against the outer container for the second component and possibly further propellant is known, in which the inner container via the Valve by rotating the valve Valve tube can be opened against the valve seat in the outer container.
  • the outer container on the valve plate has a tube element extending in the direction of the can bottom, in the tube element there is a gear connected to the valve tube via an extension through the valve body, which on rotation of the valve tube a pin acts in the direction of the lower end of the tubular element and the inner container is detachably arranged at the lower end of the tubular element and is hermetically sealed against the inner of the tubular element by a sealing element.
  • a downward movement of the pin is triggered, which acts against the inner container and irreversibly detaches it from the tube element.
  • the aim of the invention is therefore to provide a two-component pressure can with a second container arranged underneath the valve device, which is simple to manufacture, can be stored safely and is protected against unintentional triggering, a reliable triggering followed by complete mixing of the two components and easy filling of both the inner and the outer container.
  • the inner container should be secured against undesired displacement when the pressure cell is filled by the valve with propellant.
  • a pressure can of the type described in the introduction in which the element is designed as a screw element and engages with an external thread in an internal thread of the tubular element arranged above the inner container, so that a rotary movement of the valve tube is transmitted to the screw element via the engaging element and this triggers the downward movement of the screw element.
  • a rotational movement exerted on the valve is transmitted to the screw element via the valve stem and the associated engagement element and continues as propulsion on the inner container arranged at the end of the tubular element.
  • the inner container is detached or blasted off from the end of the tubular element, so that any content that may be under the pressure of a propellant gas pours into the content of the outer container and mixes with it, if necessary, with shaking.
  • the prerequisite for the blasting process is the rotary movement on the valve tube; Simply applying pressure is not converted into propulsion thanks to the toothing of the threads.
  • Conventional tin cans or drawn aluminum cans can be used as pressure cans.
  • the tubular element is fixed, for example, to a concentric projection of the valve plate which extends into the interior of the can.
  • it is in the pipe element around a plastic pipe which is pushed tightly onto this concentric projection of the valve plate, so that it extends vertically down from the valve into the pressure cell.
  • it has passages in the wall, which allow foam mass to pass through when the pressure cell is emptied or from filling material when the pressure cell is filled.
  • tubular element has at its valve-side end an inner circumferential groove in which a concentric projection engages either of the valve plate or in particular of the valve body.
  • a circumferential step-like inward projection or such a protrusion can also be provided, which engages behind a circumferential projection of the valve body or valve plate, or a combination of groove and projection.
  • the rotary movement of the valve against the valve seat for opening the inner container is converted into a downward movement by means of a screw element.
  • This is done by the interaction of the engagement element at the lower end of the valve tube with the receptacle of the screw element.
  • the engagement element arranged on the valve tube expediently consists of a polygonal end piece, for example a hexagon.
  • any other design of the engaging element can also be used, provided that the toothing necessary for transmitting the rotary movement is present.
  • the engaging element is preferably mounted or guided vertically displaceably in the receptacle, so that the can can be filled by depressing the valve tube, without detaching the tubular element with the inner container.
  • the engaging element and the receptacle are also long enough to ensure interaction until the inner container is completely detached when the screwing element is screwed down.
  • Valve tube, engaging element and screw element as well as the tube element and the inner container consist of suitable customary materials, for example plastic, such as polyethylene or polypropylene.
  • the inner container is located on the side of the tubular element facing away from the valve.
  • the inner container is expediently pushed into the tubular element with its upper, open end, a seal being arranged between the outer wall of the inner container and the inner wall of the tubular element.
  • a further seal which is preferably formed between the screw element and the tubular element, an effective separation of the contents of the inner container from the outer container is achieved. This separation is eliminated by the downward movement of the screw element described above when the valve tube rotates in that the screw element advances against the inner container and pushes it out of its storage at the lower end of the tube element.
  • the content of the inner container is released and - if there is a corresponding overpressure in the inner container compared to the outer container - is also driven out immediately. After triggering and, if necessary, further mixing by shaking, the two-component pressure cell is ready for use.
  • the seal between the inner container and the tubular element or the screw element and the tubular element are preferably designed as O-rings that run in appropriately designed ring grooves.
  • the engagement element is expediently arranged directly below the plate, which supports the valve tube against the underside of the valve body.
  • This plate preferably engages in a round extension of the receptacle of the screw element, but without extending to its lower end, so that it can be pushed in further by depressing the valve tube.
  • An annular seal in a groove in the plate prevents the filling material from penetrating into the receptacle.
  • the pressure cell according to the invention expediently has a handling aid on the valve tube to support the rotary movement.
  • This handling aid can be screwed onto the valve tube, it being important to ensure that the pitches of the screw thread on the valve tube and on the screw element or on the tube element are such that the handling aid is prevented from turning freely when triggered.
  • a handling aid consists of an extension of the valve tube, which can be angled in the upper area, and has perpendicularly projecting cross struts in the area of the valve tube, which serve to support the rotary movement and, overall, result in a cross shape for the extension and the struts.
  • the pressure cell according to the invention is also equipped with a valve that can be used in both directions, which makes it easier to fill the pressure cell.
  • a valve that can be used in both directions, which makes it easier to fill the pressure cell.
  • This makes it possible to first fill the outer container with the prepolymer, for example a two-component foam, then insert the valve insert with the inner container attached and filled, and crimp it with the can, and finally the propellant gas required to dispense the filling into the one already fill the closed container through the valve pipe and appropriate openings in the pipe element.
  • the entire contents of the outer container can also be introduced in this way.
  • the pressure vessel shown in the figures consists of a frame 1, which is closed at one end with a dome 2.
  • the dome 2 has a flanged edge 3, which holds the dome 2 on the relevant end of the frame 1 and at the same time brings about a tight connection of the parts.
  • the pressure vessel dome is made of a round blank, ie a round plate, a molded part cut out of sheet metal, which has been given the arched shape shown in the drawing.
  • the inner edge of the round blank, as shown at 4 is flanged and receives the valve 5.
  • the valve plate 6 is in turn crimped with its edge 7 around the edge 4 of the round blank and thereby sealed against it.
  • a rubber stopper 8 is seated in the center of the valve plate, which in turn has a flange-shaped widening 9 on the underside 10 of the valve plate 6 is supported and penetrated by a hollow valve tube 12.
  • This valve tube has an outer collar 13 which is supported on the outer edge 14 of the plug.
  • the valve tube 12 is closed at its lower end by a plate 15.
  • One or more passages 16 become accessible when the valve is tilted or pressed, and serve to promote the contents of the can.
  • the bottom of the pressure cell is formed by a curved plate 17, which is flanged with its edge 18 around the relevant end of the frame 1.
  • the plate 6 of the valve device 5 is sunk downward in its central region and forms an edge 20 which extends concentrically around the rubber stopper 8 and projects into the interior of the can, which can also project radially into the interior of the can.
  • the projection or the edge 20 serves as a seat for an adjoining tubular element 21 which has an inner container 23 at its lower end.

  • the seat of the tubular element 21 on the projection 20 is in any case so tight that a separation via the release mechanism for the inner container is not possible. According to a special embodiment, this can also be done in that the edge 20 is widened to form a projection which is engaged by a projection on the upper edge of the tubular element 21.

  • the circular extension 28 of the hexagonal receptacle 30 of the screw element 22 which extends into the screw element 22 by more than the thickness of the plate 15, permits vertical play of the valve tube 12.
  • the engagement element 26 does not include the receptacle 30 fills down to the floor, but also leaves space there. In this way, the can can be filled through the valve tube by pressing down the valve tube 12.
  • the screw element 22 also has a recess 27 in the outer wall region, which leaves a space between the wall of the tubular element 21 and the inserted screw element 22 in the region of this recess 27.
  • the openings 24 are arranged within this free space, which allow the filling material to pass into the interior of the container when it is being filled through the valve tube 12 and into the valve tube 12 when the foam is being dispensed from the interior of the container.
