Definitions

  • the invention relates to a valve for a gas container such as a gas cylinder or a gas tank, wherein the valve preferably has a thread with which the valve is screwed into the gas container.
  • the valve may also be attached to the gas container in another way, for example screwed tightly to the gas container with the aid of screws.
  • the gas container may be, for example, a fuel gas bottle or propellant gas bottle of various sizes, or a gas tank kept in an upright position in an RV, for example in an upright position. can be arranged on a forklift or stationary engine in a horizontal position. It may be small gas containers or large containers, wherein the use of the valve according to the invention is not limited to any size.
  • Very widespread gas cylinder have a filling weight of about 1 1 kg or about 14 kg and are filled with LPG from propane or butane or a propane / butane mixture.
  • LPG propane or butane or a propane / butane mixture.
  • Such fuel gas cylinders are used for a variety of purposes in the household or in the trade.
  • the gas from such bottles can be used in gaseous phase for all domestic or commercial purposes or in its liquid phase e.g. used to drive motors.
  • gas containers of the type considered are often made of steel, so they have a considerable weight. Meanwhile, gas containers are also out accordingly suitable aluminum alloys that are sometimes even corrosion resistant and always much easier to handle due to their significantly lower weight. Also with respect to the material of the gas tank, there is no limitation on the valve used.
  • Bursting a bottle outdoors can also have devastating consequences, especially when there are people around. Depending on how or where the bottle tears, it will fly into the air or sideways away. When a bottle explodes in the open air, the shockwave also does damage enough, but the flying parts can be catastrophic. In war, they can even be used as bombs.
  • bottle bursts are made to check that they meet the legal requirements, this is not done with gas or air, but with water.
  • the bottle is filled to the brim with water and then further water is introduced into the already filled bottle under pressure, whereby the internal pressure increases more and more, until it finally comes to bursting.
  • the gas container is not equipped with a simple valve but with a safety valve, it will open when the internal pressure of the gas container is reached, allowing gas to escape until the pressure drops below this critical pressure, after which the safety valve will generally spring - closes again. If the safety valve works properly, thus rupture of the gas container can be excluded only by internal pressure.
  • the invention provides that the valve is provided with a sealing device which melts upon reaching a predetermined critical temperature, so that all the gas can flow out of the gas container. In this way, it is ensured that no dangerous overpressure can form in the gas container when exposed to heat, which could lead to a rupture or even explosion of the container.
  • a gas container with the valve according to the invention is fire-resistant or fire-resistant. As long as a gas container with safety valve is not exposed to this critical temperature, its safety valve works as intended.
  • the arrangement and design of a fusible sealing device can be realized in many ways.
  • valves have a preferably tubular extension with an internal thread into which the valve is screwed with its mating thread.
  • a tubular extension for example, a thick flange with internal thread can be provided.
  • a fusible sealing device for example, in the region of the threaded engagement, a sealing ring, a sealing tape or a sealing paste can be arranged, which melts upon reaching a certain, predetermined temperature.
  • the appropriate dimensions of the sealing device used in each case can be determined by simple tests. It is important that upon reaching 'critical temperature, the sealing means melts the extent that all of the gas can escape from the gas tank.
  • the sealing device preferably consists of a sealing disc, which is acted upon by a spring in the closed position and is moved upon reaching a predetermined gas pressure in the container in the open position, as is usual in a safety valve.
  • the sealing disk should consist of a fusible material, of course, such Characteristics must also fulfill the normal safety functions (opening and closing the valve).
  • the sealing disc may be made of a suitable and approved material such as PT1000 and have a thickness of 1 to 3 mm, preferably about 2 mm.
  • PT1000 a suitable and approved material
  • the desired effect can also be achieved in the form of a cylinder or a sphere of appropriate dimensions.
  • a safety valve in the manner described above in connection with the simple valve in the region of the threaded engagement can be sealed by a fusible sealing device. This may be provided in addition to or instead of a fusible sealing disc within the safety valve.
  • the temperature at which the sealing device melts should be between 100 ° C and 200 ° C, preferably between 120 ° C and 180 ° C, with a melting temperature of about 150 ° C being most preferred.
  • the invention is not limited to the specified temperatures, which may be higher or lower depending on the gas container and hazardous situation.
  • the basic idea of the present invention can also be realized in another way by providing the gas container with a meltable sealing device independently of its valve.
  • a stopper closing the opening may be screwed into the wall of the gas container (or, for example, in an associated projection), the area of the threaded engagement being sealed by a fusible sealing device, for example of the type mentioned above.
  • a safety measure can also be provided in addition to the valve according to the invention.

  • the valve 1 shown in Figures 1 and 2 includes a valve body 2, the lower, slightly conically narrowing approach 3 is provided with an external thread 4, with which the valve 1 in a sleeve 24 of a gas container 25 can be screwed.
  • the gas inlet channel 5 is closed at its upper end by a plug 6 which is received in a recess of a piston 7 which is movable upwards and downwards by a handwheel 8 to open a gas outlet channel 9 in a lateral projection 10 of the valve 1 or close.

  • the sealing device consists of a fusible sealing ring or a fusible sealing tape or of a fusible sealing paste, which securely seals the thread engagement below the critical melting temperature.

Openings 22 in the cap 21 are closed by a dust stopper 23.
  • the sealing disk 17 and / or the spring holder 1 8 according to the invention may consist wholly or partly of a material which melts upon reaching a predetermined critical temperature, so that the entire gas can escape from the gas container.
