Definitions
- the present invention relates to a valve for closing a gas container, the valve comprising a valve body with a continuous longitudinal bore along a longitudinal axis, in which longitudinal bore a displaceably guided valve tappet is mounted, the valve body extending in a longitudinal direction parallel to the longitudinal axis from a connection area with a end surface on the connection side to a fastening area with an end surface on the gas container side, the fastening area having a smaller diameter than the connection area and the connection area having a stop surface in order to provide a stop for a base body head of the gas container when the fastening area is inserted through an opening in the base body head into the latter .
- Gas containers filled with gas can be connected in a gas-tight manner to a device, for example a soda siphon, a whipped cream siphon or a pressure regulator, in order to ensure an appropriate gas supply to the siphon or the device.
- a device for example a soda siphon, a whipped cream siphon or a pressure regulator, in order to ensure an appropriate gas supply to the siphon or the device.
- EP 0867 656 B1 discloses a pressurized gas capsule with a valve body, the valve body being pressed to the gas tank only via a simple groove, so that there is a risk of the valve body being pushed out of the gas tank at high pressure.
- the valve body In order to limit the freedom of movement of a valve tappet that is mounted displaceably along a longitudinal axis in a continuous longitudinal bore, the valve body has projections that protrude radially inward only in a plane that is normal to the longitudinal axis.
- valve according to the invention even at high pressure of the gas in the gas tank, protection should be ensured against the valve or a valve body of the valve being pushed out or pushed out of the gas tank, with preferably additionally a secured pressure-based movement and mounting of a displaceable valve in the valve body mounted valve tappet should be guaranteed.
- a valve for closing a gas container has a valve comprising a valve body with a continuous longitudinal bore along a longitudinal axis, in which longitudinal bore a displaceably guided valve tappet is mounted, the valve body extending in a longitudinal direction parallel to the longitudinal axis from a connection area with an end face on the connection side to a fastening area with an end face on the gas container side, the fastening area having a smaller diameter than the connection area and the connection area having a stop surface in order to provide a stop for a base body head of the gas container when the fastening area passes through an opening in the base body head is inserted into this, according to the invention that the valve body has a double groove on the lateral surface in the fastening area, the double groove being two following one another in the longitudinal direction ing individual grooves, which are separated from one another by a sealing lug pointing away from the longitudinal axis in order to enable gas-tight compression of the base body head with the fastening area in the area of the double
- connection side and "gas tank side” are to be understood with regard to the intended use. Likewise, one could speak of a first end face (instead of an end face on the connection side) and a second end face (instead of an end face on the gas container side).
- a double compression of the valve body with the gas container by means of a forming process, preferably a rolling process (a manufacturing process known per se for forming rotationally symmetrical semi-finished products, whereby in the case of tubular semi-finished products, the controlled closing of internal and/or external shape-determining tools and continuous rolling on the beads or grooves running around the workpiece can be produced), which can reliably prevent the gas container from bursting, in particular in the area of the gas container neck, or the valve body from being pressed out of the gas container neck or the head of the base body at more than 500 bar, preferably up to a maximum pressure of 550 bar.
- a rolling process a manufacturing process known per se for forming rotationally symmetrical semi-finished products, whereby in the case of tubular semi-finished products, the controlled closing of internal and/or external shape-determining tools and continuous rolling on the beads or grooves running around the workpiece can be produced
- such an arrangement ensures that the gas container at a pressure that is at a maximum permissible filling factor of 0.75 kg/1 (with carbon dioxide (C02) or nitrous oxide (N20)) and a temperature of approx. 130°C, preserves its integrity or shape.
- the limited available installation space is optimally taken into account by the double groove.
- connection area extends in the longitudinal direction from an initial area (comprising the end face on the connection side) to an end area (comprising the stop face).
- the diameter of the connection area, particularly in its end area, is larger than the diameter of the fastening area, which typically applies to the entire fastening area.
- Each individual groove has an individual groove base.
- the sealing lug protrudes beyond these individual groove bases.
- the fastening area is preferably pushed completely into the head of the base body or to such an extent that the head of the base body makes contact with the stop surface acting as a stop.
- the continuous longitudinal bore comprises at least three bore sections with at least two different diameters. This enables the drill sections to be functionalized differently, with larger diameters being advantageous with regard to unhindered gas flow, for example, and a smaller diameter proving to be advantageous for the bearing of the valve tappet.
- At least one first drilling section is arranged in the connection area and that at least a second and third drilling section are arranged in the fastening area.
- This arrangement not only proves to be particularly favorable in terms of production technology, but can also be advantageous with regard to the different functionality of the individual drilling sections.
- the bore section provided for mounting the valve tappet is arranged in the fastening area, a mechanically extremely stable mounting is ensured when the fastening area is pushed into the base body head of the gas container and pressed gas-tight with it.
- more than one first drilling section is arranged in the connection area and/or that more than two drilling sections (or more than the second drilling section and the third drilling section, e.g. a fourth or a fourth and a fifth drilling section) are provided in the fastening area could be.
- the second drilling section located between the first drilling section and the third drilling section has a smaller diameter than the first drilling section and the third drilling section, with the valve tappet being slidably mounted in the second drilling section is.
- the valve body has a first snap-in lug arrangement in the longitudinal bore in the fastening area, preferably in a third bore section of the longitudinal bore, through which first snap-in lug arrangement a section-wise narrowing of the longitudinal bore in the fastening area, preferably in the third Drilling section, is ensured, wherein the first snap-in nose arrangement has at least one bulge pointing towards the longitudinal axis.
- This first snap-in lug arrangement serves to ensure a secure, pressure-based movement and retention of the valve tappet in the valve body while the gas container is being filled with gas.
- valve tappet can be moved from a closed position, in which the valve or the longitudinal bore is gas-tightly closed by the valve tappet, along the longitudinal axis in the longitudinal direction to a filling position.
- the valve tappet releases the valve or the longitudinal bore for gas, so that gas can flow through the valve or the longitudinal bore, the valve tappet being in contact with the first snap-in nose arrangement.
- the first snap-in lug arrangement prevents further movement of the valve tappet in the longitudinal direction by means of a positive fit.
- valve tappet can be pushed at least in sections over the first snap-in nose arrangement or over its at least one bulge, with the at least one bulge receding elastically away from the longitudinal axis. This elasticity can be ensured by the choice of material for the valve body.
- the first snap-in lug arrangement comprises three bulges, which are arranged at least in sections in a plane normal to the longitudinal axis. This narrowing in sections, caused by the three bulges, causes a particularly reliable positive position fixing of the valve tappet. Angular spacing of the bulges from one another allows for unhindered gas flow when the valve stem is in the fill position and abuts the first snap lug assembly.
- the three bulges of the first snap-in nose arrangement are arranged, preferably symmetrically, at an angular distance of 120° from one another, the angular distance being measured around the longitudinal axis.
- the valve body has a second snap lug arrangement in the longitudinal bore in the fastening area, preferably in the third bore section, between the first snap lug arrangement and the end surface on the gas container side, through which second snap lug arrangement a further narrowing of the longitudinal bore in the fastening area is achieved in sections , preferably in the third drilling section, is ensured, with the second snap-in lug arrangement having at least one bulge pointing towards the longitudinal axis.
- This second snap-in lug arrangement is used for secure pressure-based movement and retention of the valve tappet in the valve body while the gas tank is being emptied, with the gas flowing out of the gas tank into a device, preferably into a siphon.
- valve tappet in this emptying position, the valve tappet is partially pushed over the first snap-in lug arrangement in the longitudinal direction, so that a portion of the valve tappet is arranged between the first and the second snap-in lug arrangement.
- Another move in Longitudinally beyond the second snap-in lug arrangement is basically prevented by positive locking.
- valve tappet can be pushed at least in sections over the second snap-in lug arrangement or over its at least one bulge, with the at least one bulge receding elastically away from the longitudinal axis.
- This elasticity can be ensured by the choice of material for the valve body.
- valve tappet when the valve is assembled, the valve tappet can be pushed counter to the longitudinal direction over the second snap-in lug arrangement and over the first snap-in lug arrangement.
- a particularly preferred embodiment of the valve according to the invention provides for the second snap-in lug arrangement to have three bulges, which are arranged at least in sections in a plane normal to the longitudinal axis. This narrowing in sections, caused by the three bulges, causes a reliable, form-fit positional fixing of the valve tappet.
- Angular spacing of the lobes of the second snap tab assembly allows for unrestricted gas flow when the valve stem is in the deflation position and at the second
- the three bulges of the second snap-in lug arrangement are preferably symmetrically spaced at an angular distance of 120° are arranged to each other, the angular distance being measured around the longitudinal axis.
- the bulges of the first and second snap-in lug arrangements are congruent to one another or rotated by 60° to one another, viewed along the longitudinal axis are arranged.
- the valve tappet has a thickening which is directed towards the end surface on the gas container side and is at least partially conical and which at least in sections, in particular in an end region pointing towards the end surface on the gas container side, has a maximum diameter which is larger than the diameter of the narrowing in sections formed by the first snap-in nose arrangement.
- this in particular defines the filling position, i.e. when the plunger moves out of the closed position in the longitudinal direction until it abuts against the first snap-in nose arrangement.
- Analog is provided in a particularly preferred embodiment of the valve according to the invention that the Maximum diameter of the thickening is greater than the diameter of the further narrowing in sections formed by the second snap-in lug arrangement. As already explained above, this defines in particular the emptying position, ie when the valve tappet moves further in the longitudinal direction from the filling position,
- valve tappet serves on the one hand as a sealing element to the valve body and on the other hand as an opening element.
- the maximum diameter of the valve tappet is smaller than a diameter of an opening cross section of the longitudinal bore in the fastening area or the third bore section. This allows gas to flow past between the thickening and the inner wall of the longitudinal bore or the inner wall of the third bore section.
- valve tappet is made of metal, preferably steel or stainless steel or brass, or ceramic.
- the valve body is made from a high-temperature-resistant plastic, in particular from polyethersulfone (PES) or polysulfone (PSU) or polyetheretherketone (PEEK) or polyphenylene sulfide (PPS) or polyphenylsulfone (PPSU) or polyetherimide (PEI). , is manufactured.
