Definitions

  • the present invention relates to a tilt valve according to the preamble of claim 1 for discharging foam and other media. These valves are used in particular for the discharge of PU foam, but also in the food industry.
  • the known tilt valves have a valve disk which is crimped with a container body.
  • a valve body with a holding opening is held in a central opening in the valve disk.
  • the valve body also referred to as a fitting, has a sealing surface serving as a valve seat on a side facing away from the valve disk.
  • a valve element is disposed in the retaining opening of the valve body and has a tubular portion with a sealing flange at one end and inlet openings in the tube wall near the sealing flange. In the closed position of the valve, the sealing flange bears against the sealing surface and prevents the discharge of the medium to be discharged via the inlet openings into the tubular section of the valve element.
  • a gap between Abdichtflansch and sealing surface is formed, passes through a medium to be discharged to the inlet opening and exits through this and the tubular portion.
  • Out DE 41 30 728 A1 is known an output device for pressurized gas cans, which is closable by means of a dispensing valve and having a throttle nozzle assembly which is intended to keep the dispensing stream substantially constant.
  • the invention has for its object to provide a tilt valve, which ensures a simple flow of constant mass flow from the container even with falling pressure.
  • the tilting valve according to the invention with the features of the preamble of claim 1 also has a resiliently biased or elastic locking body which is arranged in the tubular portion of the valve element and depending on the pressure in the container, the inlet opening in the valve element releases or at least partially closes. It is so that with increasing pressure, the inlet opening is increasingly released, whereby with decreasing pressure, the inlet opening in the tubular portion of the valve element increases increasingly.
  • the blocking body is designed as an elastic membrane element.
  • the elastic membrane element is pressed deeper into the outlet channel depending on the intensity of the pressure and thus partially closes off the inlet opening depending on the pressure value.
  • the membrane element preferably has a closure region adapted to the cross-section of the valve element in the region of the inlet opening and a holding region protruding from the valve element.
  • the holding portion preferably preferably has a circumferential flange which is curved away from the valve member and the closure portion in a the release opening releasing Biased position. With the holding region of the closure region is resiliently mounted, wherein the pressure in the interior acts against the spring force.
  • the shutter portion has a bottom and a cylindrical side wall, the shutter portion being opened toward the holding portion.
  • the valve element has a cap receiving the membrane element.
  • the cap secures the retaining region of the membrane element to the valve element and has at least one opening, so that the membrane element is acted on by the internal pressure of the container.
  • the cap surrounds the sealing flange at least partially and is latched thereto.
  • the inlet opening is formed as a slot which extends in the axial direction of the valve element. With almost completely discharged medium, the inlet opening is completely released. The released inlet opening allows the maximum leakage of the medium when the pressure drops. In substantially complete pressurization of the container, the elastic membrane element partially closes the inlet opening.
  • valve element has at least four spaced inlet openings.
  • FIG. 1 shows a valve element 10 according to the invention with a protruding Ventilstem 12 and an integrally formed therewith valve member 14 which has a sealing surface 16.
  • the valve element 10 has an outlet opening 18 through which the medium to be discharged emerges.
  • the valve element has an attached cap 20 with passage openings 22.
  • the cap 20 is in a circumferential flange 24 which partially forms the sealing surface 16, locked.
  • the pot-shaped executed cap 20 has on its inner wall correspondingly shaped locking lugs (not numbered), which engage in a corresponding circumferential recess (not numbered) in the flange 24.
  • the cap 20 has a peripheral shoulder 26 which reduces the inner diameter in the cap.
  • the abutment surface 16 is formed by the surface of the flange 24 and the edge of the cap 20.
  • an elastic membrane element 28 is inserted.
  • the membrane element 28 has a projecting into the outlet channel 30 cylindrical portion 32 and a voltage applied to the flange 24 on the side facing away from the outlet opening 18 holding portion 34.
  • the holding portion 34 is clamped along its circumference between the shoulder 26 of the cap 20 and the flange 24 ,
  • FIG. 1 the elastic membrane element is pressed into the maximum passage 30 and partially closes the inlet openings 36.
  • FIG. 2 shows the elastic membrane element 28 in a retracted position in which the inlet openings 36 in the channel 30 are released.
  • the elastic membrane element 28 is biased by its holding portion and its clamping fixation by the cap 20 resiliently in the retracted position.
  • FIG. 1 shows the valve element according to the invention at a high pressure in the container, which pushes the elastic membrane element 28 into the through-channel 30.
  • FIG. 2 shows the elastic membrane element 28 at low pressure in a container in which the bias by the holding portion 34 is sufficient to withdraw the closure portion 32 from the passageway and completely release the inlet openings.
  • the elastic membrane element thus controls the mass flow entering the through-channel 30 as a function of the pressure.
  • FIG. 3 shows the complete structure of the tilt valve according to the invention with the valve element 10 from the Figures 1 and 2 ,
  • the valve element 10 is inserted into a valve body 38.
  • the valve body 38 has on its side facing the sealing surface 16 a valve seat forming the sealing surface 40.
  • the valve body 38th abuts against the valve element 10 and engages with a projection 42 in a recess 44 a.
  • the valve member 10 is secured by a projection 46 on the valve stem against axial displacement into the container.
  • the valve plate 48 Connected to the valve body 38 is the valve plate 48, which projects radially outward.
  • the valve disk 48 is crimped along the outer circumference with a container for the medium to be discharged, wherein here preferably a seal 50 made of Buna is used.
  • FIG. 3 shows the valve according to the invention in its closed position.
  • the stem 12 is tilted in the valve body and a gap (not shown) is formed between the sealing surface 16 of the valve member 40 and the valve body.
  • a medium in the container enters the gap through the internal pressure of the container and into the channel 30 via the inlet opening 36.
  • the mass flow depends on the size of the released inlet opening 36 for the given pressure. This in turn is adjusted by the elastic membrane element 28 pressure-dependent.
  • valve member 56 has again a Ventilstem 58 and a valve member 60.
  • the valve member 60 has a bearing surface 62 which is integrally formed.
  • the passage 64 is closed at the side facing away from the outlet opening 66 side.
  • the sealing surface 62 moves away from the valve body 54 and the pressurized medium passes through the inlet openings 68 in the outlet channel 64th
