Definitions

  • the invention relates to a valve, in particular for discharging foaming agents from pressure vessels, which closes the pressure vessel to the outside and having an outlet opening with a moving light arranged closure member which is fixed by a spring tongue, which is positively and / or non-positively on the inside of a valve disk , Is held in closed position and releases an external outlet for an outlet opening for existing in the pressure vessel foaming agent, wherein the valve is mounted on a valve cover designed as a container lid.
  • Assembly foams especially polyurethane foams, have found a wide field of application in the art. They are used in the construction sector for fastening elements such as door frames and other prefabricated parts, for closing openings and for filling cavities and bags. They are often used for thermal and acoustic insulation. Furthermore, they are suitable to avoid the formation of condensation in subsequent cavities with subsequent corrosion. For the same reasons, the automotive industry is increasingly using mounting foams.
  • the one-component polyurethane foams frequently used for foaming are formed from the prepolymer contained in the pressure vessel by the action of moisture, in particular of atmospheric moisture. After release of the mixture of blowing agent and foaming agent, a reaction takes place between the prepolymer and the moisture contained in the air. This leads to the formation of permanent Foam. Depending on the moisture content of the air curing takes place in more or less short time. At high humidity curing only takes a few minutes. The same applies to silane-terminated polyurethane foams. 1.5K and two-component foams additionally contain a separate crosslinker component in the pressure cell.
  • valves that release by tilting or pushing the path of the foam.
  • they must ensure a secure seal during transport and storage. If the seal is insufficient, moisture diffuses into the valve mechanism so that the prepolymers in the valve harden and interfere with its proper functioning. In extreme cases, the valve is completely blocked by the polymer formed therein.
  • valves which are arranged in the head or dome part of such a pressure vessel and held by a rubber seal. By tilting the valve tube or stem, the foam between the rubber seal and the end plate of the hollow tube can occur in designated cutouts in the tube wall in the tube and thereby escape from the pressure vessel.
  • tilt valves Although these tilt valves have a relatively good sealing mechanism, the tilting motion required to release the prepolymer-blowing agent mixture is generally felt to be a disadvantage.
  • the targeted spreading of the mounting foam is complicated by the fact that the outflow direction of the mixture changes by the tilting movement.
  • the tilting mechanism is poorly suited to use mechanical dispensing aids, such as spray guns. Since the valve tube can rotate in the seal, it tries to avoid the tilting movement by turning.
  • valve closure element is connected via a coil spring with a holding part as an abutment.
  • the holding part protrudes freely into the interior of the pressure vessel.
  • the spring is inserted between the holding part and valve closure element and ensures its tight fit on the valve disk. Holding part and spring are full of Mission65den media accessible.
  • This mixture of propellant and prepolymer leaves the pressure vessel during actuation of the valve closure element and thereby reaches into the region of the spring and its holding part.
  • the pressure on the valve closure element is released, this is again pressed by the spring against the valve disk, so that no more mixture can escape. Mixture, which is still in the valve chamber, is discharged by the blowing agent content.
  • poppet valves with spring mechanism are well suited for connection to spray guns. But they have the disadvantage that the function of the spring is sooner or later affected or even blocked because moisture diffuses into the valve mechanism and causes polymer formation. This means that the pressure vessel either can not be emptied regulated discharged or leaking and uncontrollably bleeds.
  • sealing portions are provided on the circumference of the valve closure element. These have at least one elastically deformable, disc-shaped portion which projects radially from the closure element and engages under deformation to the valve seat. Sealing and closure elements are made of one piece and therefore of the same material. For the deformation of these elements require a certain elasticity, on the other hand limits the contact forces and reduces the tightness.
  • Out DE 196 18 375 A1 is a valve with external coil spring known.
  • valve type with a spring tongue fixed on the valve disk as a restoring element goes off US 5,927,563 at the same time, this valve type still requires an elastic valve body, in which the closure element (Ausbringrohr) made of a rigid material is fitted.
  • the valve body itself is injection-molded onto the valve disk and at the same time serves as a sealing seat in its lower region for a sealing plate arranged below the closure element.
  • valves have quite a complex structure with a variety of details, including a rigid valve body that must be mounted or molded on the valve plate. For cost reasons, a simple structure with a reduction of the individual parts would be desirable.
  • the object of the invention is therefore to provide a valve which avoids the disadvantages of conventional valves described above. It is intended to protect against the ingress of moisture into the valve area located in the pressure vessel. Nevertheless, application aids, such as spray guns, must be able to be connected. It should be simple and ensure high reliability.
  • the invention proposes, starting from the valve of the type mentioned above, that the valve disk is designed as a valve guide for the closure part, wherein the valve guide is in a cylindrical extension of the valve disk and the valve disk has a sealing surface formed as a valve seat, with a The sealing element cooperates, wherein the valve disk and the sealing element made of rigid, not functionally conditionally deformable material, and the sealing effect is brought about by an elastic element arranged on the valve disk.
  • the valve allows proper connection of the pressure vessel to a spray gun of conventional design. Since the Ventilvärschlußelement moves through a valve stem in the direction of the pressure vessel axis, it can no longer affect the function by turning off.
  • valve closure element does not require elastically deformable details for the seal, it may as well as the valve disc made of rigid material.
  • the valve disk also offers the necessary strength from its uniform function as a cover for the pressure vessel and at the same time as a rigid valve body in order to absorb the contact forces on the valve seat surfaces.
  • a further preferred solution provides to connect a leaf spring as an elastic spring element fixed to the valve disk on its side facing the pressure vessel. In this position, they have contact with the outflowing fluid, which, however, has no contact with media that cause it to harden. In addition, they are fluidically in an area on the valve closure element, where a medium flows past rather. This situation is favored by the fact that no holding part for this spring element can lead to turbulent flow behavior in the critical area. Gluing or blocking is thus excluded. In addition, leaf springs offer less or no starting points / surfaces for gluing by the foaming agent.
  • Fig.1 shows a section through a non-inventive valve, but is suitable to explain individual aspects of the invention.
  • the valve disk 1, 2 fulfills the functions as a container lid and as a valve body. For this purpose, it has a central opening 3 for the passage of the movable valve closure element 4, 5, valve seat surfaces 6 parallel to the correspondingly engaging sealing surfaces 7 on the valve closure element and a valve stem 8 for guiding the valve closure element.
  • the valve stem serves as a sliding surface for the pressed between the two parts 4, 5 of the valve closure member seal 16.
  • With its outer diameter of the valve stem also acts as a spring guide for a coil spring 9, from below on a paragraph 10 of larger diameter engages remote from the pressure vessel part 4 of the valve closure element. In this way, the spring forces in their relaxed position pull and hold the movable valve element 4, 5 in the required position for closing against the valve seat.
  • the two parts 4, 5 of the movable valve element are screwed in this version, for example via a thread 15.
  • an O-ring 16 is pressed as a sealing element so that it rests sealingly on the valve stem 8.
  • an elastomeric disk 17 is proposed to be applied for sealing.
  • the seal against a spray gun, as shown here, also take place by an O-ring 18.
  • the two parts of the valve disk 1, 2 can be welded, glued, molded or directly, as in Fig. 2 shown to be deep-drawn from one piece.
