Definitions
- the invention relates to a pressure can with a frame, one arranged in a dome Valve, a bottom with inserted crimp plate, and on the crimp plate arranged inner sleeve with detachable closure, a plunger with a section arranged inside and outside the inner sleeve, as well as a sealing element, particularly for transport and application of reactive products for the production of foams and is suitable for surface technology.
- the invention relates primarily to the formation of pressure cans, which in addition to the liquid substances of the main components that are used to manufacture and application of polyurethane or the like foams required are, take up a second component in the inner sleeve, which with the The main components react to the finished product, the actual insulating foam.
- the invention can also be applied to two-component formulations use for other purposes, such as surface technology, for example for multi-component paints.
- the substances contained in the pressure vessel are usually liquid and consist of a prepolymer, optionally a foaming agent and the liquid propellant gas used to discharge the component.
- the further component is present and exists in a relatively small amount mostly from a compound that reacts quickly with the main component, in the case of polyurethane prepolymers with reactive isocyanate groups, for example from a crosslinker in the form of a hydroxy compound and optionally Catalysts.
- the component in the inner sleeve serves to cure and affect the quality of the foam, usually accelerate.
- the second component is usually applied just before application of the foam by blasting off the lid of the inner container into the pressure can introduced and mixed into it by shaking.
- a pressure can with a by forming one Metal existing molded part obtained one-piece bottom known.
- a The recess in this base is the neck with an external thread an additional container inserted and with the help of a screwed on from the outside Nut and the deformation of an O-ring seal between one Shoulder of the additional container and the inner edge of the bottom recess braced.
- This in turn through a piston-shaped seal inside the additional container executed and sealed rod is designed as a shaft, which rotates in the additional container neck and is supported on the inside thereof. Becomes the shaft is driven from the outside, which leads to the positive engagement of your inner end with the lid of the additional container, which thereby against the Internal pressure is blown off into the can.
- the invention itself is based on WO-A-85 00 157, in which a pressure cell for the application of one- or multi-component substances is described, the inside of an additional container receiving another component having.
- the inner container has an inner lid that over one led through the bottom of the pressure cell into the interior of the inner container Rod can be blown off.
- the plunger is inside the additional container movably mounted and arranged in the crimp plate of the can base Seal introduced.
- a pressure can according to EP-A-0 148 211 is shown in the figure 1 shown.
- Both pressure cans according to the prior art require a relatively complex Construction or assembly.
- the container suffers accordingly DE-U-82 27 229 under the relatively complicated mechanics.
- the blasting off of the Blasting lid against the relatively large internal pressure of the container forced by the rotation of the rod, but this is relative laborious and also requires a lot of effort for the sealing system.
- the pressure cell according to WO-A-85 00 157 has proven itself overall and represents a significant improvement over the utility model mentioned represents, however, the introduction of the plunger through the braced in the crimp plate Sealing rubber is problematic and requires a less than optimal geometry of the pestle.
- the pressure can WO-A-85 00 157 so that the parts of the inner sleeve become easier to have a captive and absolutely tight unit installed and that they at the same time with a relatively small force to be applied by the user Blowing off the closure part of the inner sleeve can be operated.
- the inner sleeve is molded onto the crimp plate, the inner sleeve one has a shaft for the ram protruding through the center of the crimp plate, that ends below the crimp plate, the plunger against the shaft has effective and movable within the shaft sealing element and the plunger has an inner and an outer limiting element, the limit the free path length of the ram.
- the inner sleeve of the Pressure cell is molded onto the crimp plate.
- the bead plate expediently has in the injected part openings in its bottom through which the spray compound passes and can strengthen the connection between the crimp plate and the inner sleeve.
- the inner sleeve has a protruding through the open center of the crimp plate Shaft that ends above the crimp plate.
- the Tappet acts against the inner wall of the shaft and within the Schacht movable sealing element that the inside of the inner sleeve for Seals bottom; the sealing against the inside of the can takes over on Upper end of the shaft arranged closure element, such as a lid.
- the sealing element which can be moved within the shaft, also serves as a guide of the plunger inside the inner sleeve.
- the plunger In order to set the free path length of the ram in the axial direction, the plunger has an inner and an outer limiting element, from which the inner is arranged above or on the dome side to the sealing element and the other below or on the bottom to the sealing element.
- the boundary elements prevent the plunger from getting too far out of the inner sleeve is pulled out and on the other hand when the lock is blown off the inner sleeve is pushed in too far; in both cases that would Sealing element its contact to the shaft and thus its sealing effect loses.
- the beaded plate preferably has an axially extending part in its molded part Segment that is undercut from the outside and into the the inner sleeve engages with its outer wall.
- an O-ring that on the one hand on the Sick plate exerts a certain inward tension and to other serves as an additional seal between the inner sleeve and crimp plate.
- the O-ring acts on the pressure of the blowing agent in the pressure can, which particularly affects the floor area and causes deformation there can counteract and prevent the sleeve from undermining.
- the sealing element on the tappet is also expediently an O-ring is arranged within the shaft in a circumferential groove of the plunger.
- the seal is together with the plunger along the inner wall of the Slidable shaft and allows the plunger to blast off the Insert the sleeve closure by a prescribed path length, whereby the path length is predetermined by the outer limiting element.
- the shaft expediently points at its inner or dome-side end a flat edge that serves as a support for the arranged on the plunger inner or dome-side boundary element is used.
- the inside is Limiting element a circular disk or a circular disk-shaped projection. If this circular disc lies on the edge of the shaft, there is the plunger in the lower or outer end or rest position, d. H. in the Position in which the can is secured and stored and transported can.
- the outer limiting element is below the sealing element on the tappet arranged, d. H. on the bottom. It works with an appropriate abutment together on the inner wall of the shaft, that for the limiting element defines an upper end position and thus determines how far the ram can be pushed into the shaft or the inner sleeve.
- the freedom of movement of the ram between the anchor points of the inner and of the outer limiting element corresponds to the path that the tappet travels must to the closure of the inner sleeve from its rest position to blow off safely.
- the abutment thus defines the upper or inner end position of the ram after activation of the inner sleeve.
- the outer limiting element is preferably one that runs around the plunger Projection in the form of a truncated cone that extends towards the Expanded inner sleeve or the dome of the can. That with this limiting element interacting abutments preferably consists of two mutually opposite projections of the inner wall of the shaft, which are roughly circular in shape.
- the plunger itself expediently has one cross-shaped cross-section.
- the outer limiting element In order to optimally interact with the Above described abutment for the outer limiting element to ensure the ram cross-section in the area of the outer abutment uneven, d. H. with longer and opposite each other. shorter arms.
