Se conocen cilindros que contienen gases presurizados, por ejemplo, gases refrigerantes y gases técnicos tales como nitrógeno, dióxido de carbono, oxígeno, aire comprimido y argón, consistentes en un depósito de contención de gas cerrado en la parte superior por una válvula que consiste en un cuerpo hueco, en el que fluye un tapón de sellado. La válvula se enrosca con una rosca macho a una rosca hembra de la abertura superior del depósito.Cylinders containing pressurized gases are known, for example refrigerant gases and technical gases such as nitrogen, carbon dioxide, oxygen, compressed air and argon, consisting of a gas containment tank closed at the top by a valve consisting of a hollow body, in which a sealing plug flows. The valve is screwed with a male thread to a female thread of the upper opening of the reservoir.
Hay que tener mucho cuidado al realizar las roscas de la válvula y la abertura superior del depósito que se pretende acoplar. Las tolerancias de fabricación son muy ajustadas, teniendo que garantizar el sellado de gases muy peligrosos a altas presiones.Great care must be taken when making the threads of the valve and the upper opening of the tank to be fitted. Manufacturing tolerances are very tight, having to guarantee the sealing of very dangerous gases at high pressures.
La calidad de las roscas impone controles de calidad en los componentes extremadamente rígidos, lo cual supone un desperdicio de componentes nada despreciable.The quality of the threads imposes quality controls on extremely rigid components, which means a not inconsiderable waste of components.
La nueva normativa que entrará en vigor en 2019 impondrá la prohibición de reutilizar los depósitos de los cilindros con gases presurizados, es decir, los cilindros ya no se podrán rellenar.The new regulations that will come into force in 2019 will impose the prohibition of reusing the tanks of the cylinders with pressurized gases, that is, the cylinders can no longer be refilled.
El objetivo de la presente invención es proporcionar una válvula para un cilindro con gas presurizado diferente a los conocidos y que permita cumplir con la nueva normativa que entrará en vigor en 2019.The objective of the present invention is to provide a valve for a cylinder with pressurized gas different from those known and that allows compliance with the new regulations that will come into force in 2019.

The screwing of the threaded piece of the connection 133 onto the opening Threading 22 generally continues until the remaining piece to be screwed is the part 15 provided with the ring 3 on the outside.
Al forzar el roscado adicional de la conexión 133 en la abertura 22, se daña la parte 26 de la abertura roscada 22 del depósito, en particular, la parte superior de la abertura roscada 22 del depósito, como se muestra en la Figura 7. El daño a la parte 26 de la abertura roscada 22 del depósito es irreparable y hace que el depósito 20 deje de ser reutilizable porque ya no será posible enroscar otra válvula de sellado sobre la abertura roscada 22 del depósito; la parte 26 comprende al menos 2 o 3 roscas de la abertura 22.By forcing the further threading of the connection 133 into the opening 22, the portion 26 of the threaded opening 22 of the tank, in particular, the upper part of the tank's threaded opening 22, as shown in Figure 7. Damage to part 26 of the tank's threaded opening 22 is irreparable and renders the tank 20 unreusable because It will no longer be possible to screw another sealing valve onto the threaded opening 22 of the reservoir; part 26 comprises at least 2 or 3 threads of opening 22.
Preferentemente, el depósito 20 tiene un bisel de anillo superior 28 antes de la abertura roscada 22 para facilitar la entrada de la conexión 133 en la abertura 22. Preferably, reservoir 20 has a top ring chamfer 28 before threaded opening 22 to facilitate entry of connection 133 into opening 22.
