Definitions
- the invention relates to a valve for the removal of flowable Media from a pressure-tight container using a fluid propellant in the container according to claim 1.
- Valves for so-called propellant containers are in a wide variety of variants known.
- the propellant is usually already in the Pressure vessel, whereby it is pressed in via the valve attached to the vessel becomes. Since the flow paths in the valve are relatively narrow, it is also known that Pressure fluid when filling between a seal that the valve housing seals against a dome of the valve plate and flow to the valve plate allow.
- Pressure fluid when filling between a seal that the valve housing seals against a dome of the valve plate and flow to the valve plate allow.
- a Gaseous blowing agent has become known from DE 200 02 335, between one valve stem and one in the dome of the valve plate Ring seal optionally a passage to the inside of the container create. If the valve stem is actuated by pushing it in, gaseous Flow the medium past the stem into the inside of the container and thereby the medium in the container through the hole in the stem cast out.
- the blowing agent in the container has the task, on the one hand, of the medium to expel from the pressure vessel and secondly the expelled Distribute medium in the desired manner, for example spray.
- This is hardly a problem with liquid media more viscous media are sprayed, for example gels or oils, difficulties arise.
- It is known to be a medium to be driven out in a pressure container in a separate bag that is pressure-tight is welded to the valve assembly. The medium from the bag is expelled via the gas pressure in the container outside the bag. With such an arrangement, it is particularly difficult to obtain a viscous one Spray medium in the desired manner.
- Dispense media Often there is also the problem of two stored separately in the container Dispense media simultaneously, mixing them in the dispenser or spray head become. These are media that come together react with each other, such as B. in hair dyes.
- the invention is therefore based on the object of a valve for removal to design flowable media from a pressure-tight container that even more viscous media are sprayed or atomized can, or that a simultaneous removal of two substances allows.
- the valve stem points to the upper one At the end of the stem open channel, which has a second cross hole is connected to the outside of the stem.
- the second transverse bore is blocked off by the first seal, while in the open position via the cross hole made between the channel in the stem and the inside of the container is.
- the invention is based on the fact that even with propellants, initially in the propellant container in the liquid state there is a gas phase in the upper area of the container, from which the stem is fed when the valve is open becomes.
- valve according to the invention is particularly advantageous for Propellant container, in which the medium in a bag inside the Container is stored.
- the second pressurized medium can also be used with the first to be reacted by putting both media in the spray head together come and be mixed up there.
- This method can e.g. B. at Hair dyes are used.
- both Media are stored separately in the container.
- a blowing agent is required, in particular a propellant gas, the z. B. presses on a bag containing a first medium and on the volume the second medium outside the bag. In this case it is Keep container overhead so that the second medium can be expelled can.
- the valve shown in FIGS. 1 and 2 has a valve disk 10, e.g. is formed from sheet material. It has a cathedral 12 and one radial flange 14 with an outer seal 16. The flange 14 is in a Opening of a container, not shown, attached and by compression molding and sealingly attached via the seal 16.
- the container can be a have the usual format and contain any medium to be dispensed, especially a relatively pasty medium, e.g. Gel, oil or the like. In the container there is also a fluid propellant for expelling the Medium in a manner known per se.
- the dome 12 there is an upper cylindrical section 18 of a sleeve-shaped Housing 20.
- the housing is also called a riser pipe holder.
- a hose or tube With the lower end of the housing 20 is a hose or tube connected, which is guided to the lower end of the container, not shown and through which the medium to be expelled is routed.
- Section 18 is pressed in by compression and bending deformation in the dome 12, whereby its upper cross-sectionally triangular end against an annular seal 22 abuts, which in turn bears against the ceiling portion of the dome 12.
- the housing 20 has a plurality of stepped sections below the section 18 24, 26 and 28, each in the order mentioned have smaller inner and outer diameters.
- a stem 32 is passed through. It is largely outside along its length cylindrical and provided with a central bore 34.
- the bore 34 is closed at the lower end of stem 32. Near the closed end there is a series of radial bores 36 which define the bore 34 connect to the outside of the stem 32.
- the stem 32 also has an annular channel 33 which defines the bore 34 surrounds concentrically and in the area of the sealing ring 22 via a transverse bore 35 is connected to the outside of the stem 32.
- the closed position of the valve shown is the transverse bore 35 through the Sealing ring 22 sealed.
- a spacer sleeve 42 Surrounds the cylindrical part of the stem 32 below the sealing ring 22 a spacer sleeve 42. At the upper end is the spacer sleeve with axially parallel provided in the circumferential direction evenly spaced axial ribs 44, which merge into radial ribs at the top. Over the ribs 44 the spacer sleeve 42 is supported on the sealing ring 22 and laterally through projecting portion 24 of the housing 20 is fixed. Below the ribs 44 in the transition between sections 18 and 24, the housing 20 several passages 46a.
- a second sealing ring 46 is arranged below the spacer sleeve 42 1, the bores 36 closes.
- the sealing ring 46 is supported downward over several in the circumferential direction equally spaced axially parallel ribs 48 of the housing 20 from.
- a coil spring 50 which is uniform in circumferential direction supports spaced axially parallel ribs 52 of section 28, acts against the underside of the stem 32 and tensions it upwards into the 1 shown in the closed position.
- An axial pin 52a protrudes the spring 50, which is guided on the outside by axially parallel ribs 54.
- the stem 32 is pressed down against the action the spring 50, the cross bores 36 are exposed, and the medium within of the container, not shown, can be taken along line 56 between the ribs 32 and the ribs 48 and over the transverse bores 36 and Flow channel 34 upwards and be dispensed via a dispensing head.
- a flow path 60 into the cross bore 35 Ring channel 33 released.
- the transverse bore 35 is in the open position the stem 32 with the space below the valve plate 12 in connection, so that the gas in the upper region of the container, not shown, via the ring channel 33 carried out and to support the application of the medium can be used.
- the embodiment according to Figures 3 and 4 has the same valve arrangement on like the embodiment of Figures 1 and 2. Therefore are the same parts with the same reference numerals as in Figures 1 and 2 Mistake.
- the difference from the embodiment according to FIGS. 1 and 2 lies in the fact that a laminated bag 62 is attached to section 28 of housing 20 is welded to seal. There is a relatively viscous one in the bag 62 Medium. Outside of the bag is in the container, not shown a gaseous propellant, with the help of which the contents of the pouch pass over the path 56 already shown in FIGS. 1 and 2 and a delivery head, not shown can be carried out.
- the valve is actuated also gas is fed separately in parallel to the medium to be discharged To influence the discharge process.
- the separately supplied gas can also react with the other medium brought to obtain a mixed product, e.g. B. a hair dye.
- a second medium can be placed outside the bag in the container can be driven out with the help of a propellant, which also creates a pressure on the bag.
- a propellant which also creates a pressure on the bag.
- the container with the Keep valve assembly overhead This collects the second medium in the valve area of the container and the propellant in the bottom area of the container.
- it is also possible to use the valve through the opening 46a to connect a riser pipe (not shown) that goes down into the Container is guided. In this case, removal is also normal of the container possible.
