Definitions

  • the present invention relates to a pneumatic low-pressure valve according to the preamble of patent claim 1.
  • the object of the invention is to provide a valve which is able to quickly and quietly empty a pneumatic structure or a body under pressure or to relieve the pressure.
  • the solution to the problem is given in the characterizing part of patent claim 1 with regard to its essential features and in the further claims with regard to further advantageous properties.
  • the low pressure valve according to the invention consists of a valve body with at least one outlet opening, which are closed by means of closing flaps. These flaps are moved with a pneumatic actuator that deforms under pressure.
  • the low pressure valve according to the invention is described in detail using the following figures. Show it
  • FIG. 3 shows a perspective of a low-pressure valve according to the invention
  • Fig. 4 shows a cross section through a third embodiment.
  • the low-pressure valve according to the invention is shown in cross section with two outlet openings 2 in a valve body 1, open on the left and closed on the right.
  • Closure flaps 4 press against the outlet openings.
  • the closure flaps 4 are here, for example, with the valve body 1 screwed. However, a variety of possibilities are known to the person skilled in the art to create such a connection.
  • a pneumatic actuator 5 attached between the valve body 1 and the closure flaps 4 is pressurized, so that the closure flaps 4 are bent elastically and pressed away from the outlet openings 2. If the pneumatic actuator is relieved of pressure, the closure flaps 4 close again due to their elasticity.
  • the closure flaps 4 are arranged such that they are pressed against the outlet openings 2 by the pressure difference of at most 500 mbar (5 * 10 4 Pa) between the inside and outside of the valve. In FIG. 1 they are located in the interior of a pneumatic structure 6 which is pressurized to a pressure higher than the ambient pressure.
  • sealant 3 can be applied in the area of the outlet openings 2 and the closure flaps 4. In FIG. 1, these are implemented, for example, with sealing rings 10 around the outlet openings 2.
  • the pneumatic actuator 5 is attached to the outside of the closure flaps 4 and bends the closure flaps elastically by means of tensile forces caused by the pressurization.
  • the actuator 5 is fastened here, for example, to the closure flaps 4 with tabs 11, but it can, for example, also be adhesively bonded to the closure flaps 4, it is essential to the invention that the selected type of fastening is able to transmit the tensile forces to the closure flaps.
  • the valve body 1 is preferably made of a little elastic plastic or metal, so that it is not deformed by the pressure difference. Flexible materials are suitable for the flaps 4, since they are elastically bent by the pneumatic actuator 5.
  • the flaps can be made from spring steel or bronze, but are also tough-elastic plastics suitable.
  • the pneumatic actuator 5 is made of a gas-tight and hardly stretchable material.
  • a hose made of strong PU or a fabric-reinforced hose are suitable.
  • 3 shows the first exemplary embodiment in a perspective.
  • the outlet openings 2 are arranged in two rows, each outlet opening 2 being enclosed, for example, by a sealing ring 10.
  • the pneumatic actuator 5 runs between the two rows.
  • the closure flaps 4 are screwed onto the valve body 1 here, for example, with screws 8.
  • other types of fastening such as gluing and welding are also in accordance with the invention.
  • the closure flaps are made from a rectangular plate, the plate having slots 9 on its longitudinal sides, which run against its center line, and thus a separate closure flap 4 is formed for each outlet opening 2.
  • a sealing membrane 7, for example is attached as the sealing means 3 and is pressed by the closure flaps 4 onto the sealing rings 3.
  • the valve body is closed in a ring and on its inside the closure flaps 4 and the sealing means 3 are attached in the form of sealing rings 10.
  • the actuator 5 and other components are not shown.
  • a low-pressure valve designed in this way can, for example, be placed on a pipe or hose end.
  • FIG. 3 shows only one of many configurations according to the invention.
  • inlet openings 2 can be arranged as desired in valve body 1.
  • a closure flap 4 can also cover a plurality of outlet openings 2 or a plurality of closure flaps 4 an outlet opening 2.
  • the presence of a plurality of actuators is also according to the invention.
  • the flat shape of the valve body 1 disclosed in the figures is not comprehensive, surface-adapted shapes consisting of several partial surfaces or curved shapes are also included in the inventive concept.
  • a ring-like shape was chosen for the valve body 1.
  • the closure flaps 4 are attached, which are pressed open by the actuator 5, not shown, as in the first exemplary embodiment.
  • such a valve can easily be attached to one end of a pressurized pipe.

Abstract

L'invention concerne une soupape pneumatique basse pression présentant un corps de soupape (1) et des orifices d'échappement (2) pour des structures pneumatiques (6). Ces orifices d'échappement (2) sont entourés d'anneaux d'étanchéité (3) et obturés par des clapets de fermeture (4). Un actionneur pneumatique (5) est placé entre les clapets de fermeture (4) et le corps de soupape (1). Lorsque cet actionneur pneumatique (5) est soumis à une pression, cet actionneur se déforme et courbe ainsi élastiquement les clapets de fermeture, la soupape basse pression étant alors ouverte.
