Description of drawings
Then, further set forth the present invention by the embodiment that illustrates in the diagram.Here:
Fig. 1 has shown CO in longitdinal cross-section diagram 2Compressed gas source; And
Fig. 2 has shown the elastoplast parts of the detail section II among Fig. 1.
The specific embodiment
CO 2Compressed gas source is designed to inserts, and its bung by container (Spundloch) is coupled in the container and is sealed shut bung.The bung at the middle part of container by being usually located at its upper bottom portion and under pressure, be loaded to contain CO 2Liquid.After this, bung utilizes inserts and is closed.
Integrated discharge cock (Auslaufhahn) can be used for taking out liquid, and this discharge cock is located at its side wall portion place at the lower bottom part height of container.Liquid flows out owing to internal pressure and Action of Gravity Field, until reach negative pressure above the liquid plane in the head space of container, in container.CO 2Compressed gas source is activated, in order to correctly it is adjusted and to be kept through the mode of regulating.CO 2The CO of compressed gas source supply under certain pressure 2In the head space of container, this pressure is corresponding to the CO that dissolves in liquid 2Dividing potential drop or slightly surpass this dividing potential drop.With this, guaranteed the stable emptying of container.There is not air to enter into the head space of container.The CO of liquid 2Content remains unchanged.
Very thin (laenglich-schlanker) shape and the overwhelming majority that inserts is elongation are configured radially symmetrically with respect to central axis.It mainly is made of plastics.For production, can recommend two component plastics die-casting techniques.
The inserts that is arranged in the bung installation site, that sealing container is prominent to container with housing 10.
Housing 10 within it place, end has chamber 12 to be used for CO 2(Passsitz-Aufnahme) held in the cooperation of high pressure cylinder 14.The head (this cylinder 14 can be pierced in the end of this head) of cylinder 14 is towards bung.
Housing 10 utilize outside around 16 of flanges (Kragen) be contained on the wheel rim (Boerdelrand) of bung.16 places form sealing member 18 at flange, and inserts utilizes the seal 18 and bung is sealed.
Put into the knob 20 outstanding flange 16, CO in the manipulation of this knob 20 of exceeding outwards in the housing 10 2Cylinder 14 is pierced.Knob 20 has steep outside thread 22, utilizes it, and knob 20 is screwed in the negative thread of complementary housing 10.
Pricker 24 is used for CO 2Piercing through of cylinder, linked together on the valve component structure of itself and pressure-modulation valve.The valve element utilizes elastomeric film 26 and is suspended in the axle center (Achsmitte) of housing 10.The needle point of pricker 24 and CO 2The end face of cylinder 14 is only spaced apart slightly.
Pricker 24 to CO 2In the axial adjustment action (Stellbewegung) of cylinder 14, the valve element rises from the valve seat 28 of pressure-modulation valve.Valve seat 28 is formed in housing 10 places moulding by elaxtic seal.
The slide block 30 that pricker 24 is positioned between knob 20 and the pricker 24 loads.Slide block 30 vertically is directed in housing 10 movably.When handling, knob 20 is facing to slide block 30 precessions, and slide block 30 is axially displacement therefore.
Between knob 20 and slide block 30, clamp helical compression spring (Schraubendruckfeder) 32 is arranged.Helical compression spring 32 is facing to pricker 24 and with slide block 30 pretensions.
Film 26 defines the epitrochoidal chamber in valve seat 28 downstreams of pressure-modulation valve.Epitrochoidal chamber has the earial drainage opening of side direction, before elastic sealing ring 34 is positioned at this earial drainage opening.Seal ring 34 has the function of boiler check valve.It stops liquid to arrive in the inserts.
In order to pierce through CO 2Cylinder 14, knob 20 are rotated about 90 degree.Slide block 30 is axially inwardly displaced by the screwfeed of knob 20.Pricker 24 axially upcountry is carried under the elastic deformation of film 26.The valve element rises from valve seat 28.After piercing through, CO 2Very little valve pocket (Ventilraum) before the head of cylinder 14 is in the CO under the high pressure 2Filling.
Finish 90 ° rotations of knob 20 or excessively rotation (Ueberdrehung) afterwards, slide block 30 facing to the mechanical axis of helical compression spring 32 to outwards resilience.For this reason, it is handled by pricker 24, and pricker 24 is by the elastomeric reinstatement of film 26 axially reset (zumeckstellen).Helical compression spring 32 is compacted.Pressure-modulation valve is closed, and is on a small quantity the CO under the high pressure 2Be put in the epitrochoidal chamber.CO at film 26 places 2Pressure helps the resilience of the slide block 30 of pricker manipulation.
The further opening and closing of pressure-modulation valve are determined the spring constant of the elastic behavior of film 26, helical compression spring 32 and the CO in the epitrochoidal chamber by the force balance (Kraeftegleichgewicht) at film 26 places 2Pressure has been facilitated this force balance.For the CO that emits 2The spring constant of pressure helical compression spring 32 be conclusive.
Usually, if the internal pressure in the container descends so far, that is, and the liquid beam that flows out by discharge cock too a little less than, then the user can activate CO 2Compressed gas source.But, CO 2Compressed gas source without doubt equally can be when the internal pressure in container before be still higher, certainly even fully can the primary operational motion at the container place the user in, just be activated.As long as high internal pressure is carried on the seal ring 34 before the earial drainage opening, the CO to the head space of container 2Metering just can not occur.
CO 2Compressed gas source is provided with the overvoltage safety device, and this overvoltage safety device lost efficacy and CO at pressure-modulation valve 2Work when under high uncontrollably pressure, arriving the head space of container.
As the overvoltage safety device, at the wall section of housing 10 place just bung nearby (dicht vor dem Spundloch) injection molding (angespritzt) thermoplastic elastomer body (TPE) is arranged, the part with minimum material thickness of this thermoplastic elastomer body forms the film 36 that is recessed in the wall section.
Film 36 with not yet handled to be used for CO 2The outer cylinder of cylinder 14 the knob that pierces through 20 be in flush by (in buendiger Anlage) in putting.For this reason, it is placed between adjacent two helicals (Gewindegaenge) of the outside thread 22 at knob 20 places.
Be used for CO 290 ° of rotations of cylinder 14 the knob that pierces through 20 make the window in the cylinder of film 36 and knob 20 relative.Under the internal pressure that rises uncontrollably, film 36 can flexibly expand in this window, until it is approximately ftractureing at the position of minimum material thickness under the 5.7Bar.With this, the flow path from the head space of container to the cylinder of knob 20 is unlocked, and 20 pairs of flanges 16 of this knob are not positive confinement, thereby, CO 2Can flow out to the atmosphere from the head space of container.
