El radio de dicha oquedad coincide con el de (1) y su profundidad es la precisa para que encaje en él de la manera prevista. Sobre la cara interna de la oquedad se aplican los rebajes necesarios para llevar a cabo el anclaje de ambos elementos como se verá más adelante.(g) with which the tight seal of the mechanism is achieved. In the lower part of it, and forming a single object with it, the coupling (f) to the high pressure source is placed, either by the practice of threading on its surface for direct screwing of the element onto the tank or another high-pressure dispenser, or by any other means of fixing sufficient for that purpose. An anchoring accessory, which is part of the device (3) that is intended to be used connected to the source of high pressure and that is constituted by a body of material resistant to it, which has had a hole (t) cylindrical, similarly open towards the device to be used by means of a hole (r). The radius of this cavity coincides with that of (1) and its depth is the precise one so that it fits in it as planned. The necessary recesses are applied to the internal face of the cavity to carry out the anchoring of both elements as will be seen later.
Un cilindro de material elástico (4), de igual diámetro y longitud que (b), en cuyo costado, a la distancia precisa de sus bases y de manera transversal, se ha practicado un orificio (j) que lo traspasa; dicho elemento, al ser alojado en (b) lo cierra de forma estanca y sólo permite el paso del fluido a través de j) cuando esta pieza se halla en la posición adecuada, es decir, cuando se halla en la misma orientación que (a). La misma se halla conectada, formando un sólo cuerpo, con una transmisión acabada en forma de estrella que permite, al ser accionada del modo apropiado, la rotación del elemento completo en el interior del orificio y, por tanto, el cierre del paso del fluido cuando el orificio (j) se halla en posición transversal a la dirección de circulación de aquél.A cylinder of elastic material (4), of the same diameter and length as (b), on whose side, at the precise distance from its bases and transversely, a hole (j) has been made that passes through it; said element, when housed in (b) closes it tightly and only allows the passage of the fluid through j) when this piece is in the proper position, that is, when it is in the same orientation as (a ). It is connected, forming a single body, with a star-shaped transmission that allows, when properly operated, the rotation of the entire element inside the hole and, therefore, the closing of the fluid passage when the hole (j) is transverse to its direction of circulation.
Un dispositivo de apertura y cierre de paso de fluido, consistente en una corona de material sólido (2), dispuesta alrededor del cuerpo principal en cuya cara interna se ha practicado un dentado coincidente con la estrella de la pieza (4) antes detallada y que, con su giro, permite la apertura o cierre del paso del fluido a modo de llave de paso.A fluid passage opening and closing device, consisting of a crown of solid material (2), arranged around the main body whose internal face has made a teeth coinciding with the star of the piece (4) detailed above and which , with its turn, allows the opening or closing of the passage of the fluid as a stopcock.
Un sistema de anclaje y desanclaje rápido, formado por una serie de proπriβencias (d), practicadas sobre el costado del cuerpo cilindrico (1) y de su mismo material y por tanto resistencia, que permiten el anclaje rápido del accesorio a utilizar, el cual va provisto de las ranuras precisas, a fin de que aquéllas encajen en las mismas para su deslizamiento y, una vez colocado el dispositivo en su lugar correspondiente sobre el grifo, un simple movimiento rotatorio complete el anclaje. Al abrirse el paso del fluido y crearse una cámara de mayor presión que la ambiental entre los elementos en cuestión, dichas prominencias soportan la fuerza generada por ésta sobre las superficies de ambos elementos, impidiendo el desanclaje del conjunto por efecto de las mismas.A fast anchoring and de-anchoring system, formed by a series of progrrißencias (d), practiced on the side of the cylindrical body (1) and of the same material and therefore resistance, which allow the fast anchoring of the accessory to be used, the which is provided with the precise grooves, so that they fit into them for sliding and, once the device is placed in its proper place on the tap, a simple rotary movement completes the anchor. When the passage of the fluid is opened and a chamber of greater pressure than the environmental one is created between the elements in question, said prominences withstand the force generated by it on the surfaces of both elements, preventing the disassembly of the assembly as a result of them.
Un sistema anti - apertura del paso del fluido que no permite la misma hasta que el accesorio a utilizar no se halle convenientemente anclado y que consiste en una pieza sólida (L), cuya geometría puede observarse con detalle en la figuraAn anti-opening system for the passage of the fluid that does not allow it until the accessory to be used is not properly anchored and consisting of a solid piece (L), whose geometry can be seen in detail in the figure
(2 ), montada sobre un fleje (k) e instalados ambos en el seno de un rebaje (e) practicado en la cara externa del cilindro principal (1), que bloquea el movimiento de la corona (2) antes detallada, pues ésta posee a su vez, en el lugar preciso, otro rebaje (p) similar en el que encaja la pieza (L); al ser acoplado el dispositivo a utilizar (3), tal pieza (L) se desliza sin desplazarse a través del rebaje (s) que posee este dispositivo; al realizar el movimiento rotatorio de anclaje más arriba detallado, la pieza (L) se desplaza hacia el interior de la ranura (e), comprimiendo el fleje (k) por la presión ejercida por las paredes del dispositivo (3) sobre la cara externa roma de (L), en el sentido de liberar la corona (2) y permitir su desplazamiento libre mientras (3) permanezca en la posición correcta.(2), mounted on a strap (k) and installed both within a recess (e) made on the external face of the main cylinder (1), which blocks the movement of the crown (2) detailed above, as this it also has, in the right place, another similar recess (p) in which the piece (L) fits; when the device to be used (3) is coupled, such part (L) slides without moving through the recess (s) that this device possesses; when performing the rotary anchoring movement described above, the part (L) moves into the groove (e), compressing the strap (k) by the pressure exerted by the walls of the device (3) on the external face blunt of (L), in the sense of releasing the crown (2) and allowing its free movement while (3) remains in the correct position.
Seguro bloqueante del accesorio (3), que impide el movimiento rotatorio accidental del mismo, en el sentido de impedir su desanclaje y consistente en la existencia, en el cuerpo principal (1), de una cámara (c), en contacto con el conducto coaxial, en la que se coloca una pieza sólida a modo de émbolo (h) y de la dureza precisa, de la misma longitud que (c) y cuyos costados forman un cierre estanco con las paredes de la misma, de manera que al abrirse el paso del fluido e incrementarse la presión en el seno de aquélla, se obliga a la pieza móvil a desplazarse hacia el exterior, con lo que la misma encaja en un hueco (n) practicado en el accesorio (3) a utilizar, fijándolo e impidiendo así su desanclaje hasta el cierre del paso del fluido y la purga total de la presión existente en la cámara.Locking fixture of the accessory (3), which prevents the accidental rotational movement of it, in the sense of preventing its disassembly and consisting of the existence, in the main body (1), of a chamber (c), in contact with the duct coaxial, in which a solid piece is placed as a piston (h) and of the precise hardness, of the same length as (c) and whose sides form a tight seal with the walls thereof, so that when opened the passage of the fluid and increase the pressure within it, the mobile part is forced to move outward, so that it fits into a hole (n) made in the accessory (3) to be used, fixing it and thus preventing its disassembly until the closing of the fluid passage and the total purge of the existing pressure in the chamber.
La Presente invención será de más fácil comprensión si nos referimos al siguiente ejemplo práctico de realización:The present invention will be easier to understand if we refer to the following practical example of realization:
Supongamos el caso de la utilización de cualquier mecanismo neumático, respiratorio, etc.. que tenga que acceder para su uso a una fuente de aire a alta presión, sea cual fuera ésta. A dicho mecanismo, o en contacto con él, se acopla ei dispositivo (3) más arriba citado. Por otra parte, se dispone de una fuente de aire a alta presión, en cuya salida se acopla a su vez el cuerpo cilindrico (1) dotado de la totalidad de los elementos necesarios a los que se ha hecho referencia antes.Assume the case of the use of any pneumatic, respiratory, etc. mechanism that has to access a high pressure air source for use, whatever it may be. To said mechanism, or in contact with it, the aforementioned device (3) is coupled. On the other hand, a high-pressure air source is available, at whose outlet the cylindrical body (1) is fitted, in turn, equipped with all the necessary elements referred to above.
En un primer instante los elementos (3) y (1) se hallan desensamblados y el paso del aire a través de (1) cerrado, lo que supone que el orificio (j) se halla en posición transversal con respecto al (a), impidiendo el paso del aire por dicho conducto; para ello, los elementos (2) y (4) deben encontrarse en la posición correcta de cierre, que corresponde al reflejada en la figura (3). Al hallarse los dispositivos (1) y (3) desensamblados, y como puede observarse en dicha figura, el elemento (k) se halla alojado en la ranura (p) de la corona (2),impidiendo la rotación de la misma y por tanto la apertura del paso de aire. El elemento (h), al o existir presión en la cámara que lo contiene, se halla alojado totalmente en su interior.At first, the elements (3) and (1) are disassembled and the passage of air through (1) closed, which means that the hole (j) is in a transverse position with respect to (a), preventing the passage of air through said duct; for this, the elements (2) and (4) must be in the correct closing position, which corresponds to the one shown in figure (3). When the devices (1) and (3) are disassembled, and as can be seen in said figure, the element (k) is housed in the groove (p) of the crown (2), preventing its rotation and by Both the opening of the air passage. The element (h), when there is pressure in the chamber that contains it, is completely housed inside.
A continuación se dispone el elemento (3) sobre (1) en la posición correcta, para su uso, lo cual supone su deslizamiento vertical a lo largo del cilindro (1), siempre y cuando la prominencia (d) del elementa (1) coincida con la ranura (s) del elemento (3) que le sirve de guía, para completar el anclaje con la rotación horizontal de éste a fin de alojar a (d) en el seno de la ranura (m); con este último movimiento se consigue a su vez el desplazamiento hacia el seno de la ranura (e) de la pieza móvil (1), la cual por la presión que ejerce sobre ella la cara interna de (3). comprime el fleje (k), con lo que se libera la corona (2) permitiendo su movimiento rotatorio al objeto de abrir el paso del aire como se verá a continuación.Next, the element (3) is placed on (1) in the correct position, for its use, which implies its vertical sliding along the cylinder (1), as long as the prominence (d) of the element (1) match the groove (s) of the element (3) that guides you, to complete the anchor with the horizontal rotation of this in order to accommodate (d) within the groove (m); with this last movement the displacement towards the sine of the groove (e) of the moving part (1) is achieved, which by the pressure exerted on it by the internal face of (3). compress the strap (k), which releases the crown (2) allowing its rotational movement in order to open the air passage as will be seen below.
Una vez instalado adecuadamente el elemento (3) sobre (1), la apertura del paso de aire supondrá la rotación de la corona (2) en el sentido adecuado, a consecuencia de lo cual, y gracias a la disposición de (4) en su seno, se consigue la rotación de éste en el sentido de disponer el orificio (j) en la misma orientación que (a) y, por tanto la apertura de la circulación del aire. Una consecuencia directa de ello será el incremento de la presión interna en el seno de la parte superior de (a) y, por tanto también en el seno de la cámara (c), debido a lo cual, la pared interna del elemento (h) sufrirá la aplicación de una fuerza proporcional a dicha presión y, consecuentemente, se desplazará en el sentido de ampliar el volumen de la cámara (c) antes citada, alojándose con dicho movimiento en el seno de la cámara (n), perteneciente al elemento (3), impidiendo, mientras el conducto de aire siga abierto y exista mayor presión en su seno, el movimiento rotatorio del elemento (3) en el sentido de liberarlo de su anclaje con (1).Once the element (3) is properly installed on (1), the opening of the air passage will involve the rotation of the crown (2) in the proper direction, as a result of which, and thanks to the arrangement of (4) in its sine, its rotation is achieved in the sense of arranging the hole (j) in the same orientation as (a) and, therefore, the opening of the air circulation. A direct consequence of this will be the increase in internal pressure within the upper part of (a) and, therefore, also within the chamber (c), due to which, the internal wall of the element (h ) it will suffer the application of a force proportional to said pressure and, consequently, will move in the sense of expanding the volume of the aforementioned chamber (c), staying with said movement within the chamber (n), belonging to the element (3), preventing, as long as the air duct remains open and there is greater pressure within it, the rotational movement of the element (3) in the sense of releasing it from its anchor with (1).
El seguirniento de los anteriores pasos supone la operatividad del mecanismo a utiliza, por lo que en este momento, sea cual fuere el dispositivo acoplado al grifo, estaría dispuesto para su funcionamiento.Following the previous steps assumes the operability of the mechanism to be used, so at this time, whatever the device is attached to the tap, it would be ready for operation.
Por lo que se refiere al desanclaje del sistema antes propuesto, el mismo pasaría por el cierre previo del paso de aire, consistente el mismo en la rotación de (2), en el sentido inverso al de apertura y la consiguiente disposición de (j) en dirección transversal a la del flujo de aire, hasta la posición original. Una vez aislado el mecanismo de la fuente de alta presión será preciso el purgado del aire a presión remanente en el interior de circuito hasta que dicha presión se iguale con la externa, lo cual se obtiene haciendo uso del mecanismo a utilizar, ya sea abriendo una válvula de paso acoplada a él o por su propio uso. Una vez equilibrada la presión interna del mecanismo con la externa se está en condiciones de desanclar el elemento (3) de (1), pues al no existir mayor presión en el seno de (c), el elemento (h) se hallará libre para ser desplazado hacia el interior de dicho seno al producirse el movimiento rotatorio, inverso al de anclaje; del elemento (3), con lo que el mismo podrá ser removido de su posición sobre (1), con lo cual se consigue además que el elemento (k) encaje de nuevo en la ranura (p) y, por tanto disponer del sistema listo para ser usado de nuevo.With regard to the de-anchoring of the previously proposed system, it would go through the previous closing of the air passage, consisting of the rotation of (2), in the opposite direction to the opening and the consequent arrangement of (j) in the transverse direction of the air flow, to the original position. Once the mechanism of the high pressure source is isolated, it will be necessary to purge the pressurized air remaining inside the circuit until said pressure is equal to the external one, which is obtained by using the mechanism to be used, either by opening a bypass valve coupled to it or by its own use. Once the internal pressure of the mechanism is balanced with the external pressure, the element (3) of (1) can be disassembled, since there is no greater pressure within (c), the element (h) will be free for be displaced into said breast when the rotary movement occurs, inverse to that of anchoring; of the element (3), whereby it can be removed from its position on (1), whereby it is also achieved that the element (k) fits back into the groove (p) and, therefore, has the system Ready to be used again.
No se considera necesario hacer más extensa esta descripción para que cualquier experto en la materia comprenda el alcance de la invención y las ventajas que de ella se derivan.It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom.

3.- Grifo para fluidos a presión dotado de seguro de apertura del paso de fluido, el cual se vale de la existencia, anclada sobre el cilindro principal, de un elemento móvil de frenado aplicado sobre la llave de paso del fluido que, cuando el dispositivo a utilizar no se encuentra convenientemente anclado sobre el cuerpo cilindrico, impide la rotación de aquella, y cuyo anclaje supone la liberación de la misma y la consecuente posibilidad de apertura de paso. La existencia de un fleje aplicado contra el freno permite que una vez cortado el paso del fluido y desanclado accesorio, la pieza que constituye el freno regrese a su posición original de bloqueo de la llave.3.- Tap for pressurized fluids equipped with a safe opening of the fluid passage, which uses the existence, anchored on the main cylinder, of a moving braking element applied on the fluid stopcock which, when the device to be used is not conveniently anchored on the cylindrical body, prevents its rotation, and whose anchoring involves the release of it and the consequent possibility of opening passage. The existence of a strap applied against the brake allows once the passage of the fluid has been cut and the accessory removed, the part that constitutes the brake returns to its original key lock position.
4.- Grifo para fluidos a presión que comporta un elemento neumático de fijación del accesorio a utilizar que impide, una vez establecida la c-iroυlacjAn del fluido, movimientos indeseados de las partes que pudieran comportar el desanclaje accidental de los mismos. Tal elemento está constituido por un orificio ciego, abierto de forma radial, de manera que conecte con el orificio axial antes citado, sobre el costado lateral del cuerpo cilindrico principal y situado cerca de su base superior; a emás comporta un émbolo, colocado dentro de aquél y con cuyas paredes cierra de manera estanca, por lo que al abrirse el paso del fluido y generarse una mayor presión en el seno del conducto coaxial, la fuerza ejercida por la misma sobre la cara interna del émbolo lo desplace hacia el exterior del conducto y encaje con el hueco practicado al efecto sobre las cara interna del accesorio a utilizar impidiendo su movimiento mientras la fuente de alta presión permanezca activa. 4.- Tap for pressurized fluids that involves a pneumatic fixing element of the accessory to be used that prevents, once established the c-iroυlacjAn of the fluid, unwanted movements of the parts that could lead to accidental disassembly of the same. Such an element is constituted by a blind hole, open radially, so that it connects with the aforementioned axial hole, on the lateral side of the main cylindrical body and located near its upper base; On the other hand, there is a piston, placed inside it and with whose walls it closes tightly, so that when the passage of the fluid is opened and a greater pressure is generated within the coaxial duct, the force exerted by it on the inner face from the piston, move it outwards of the duct and fit with the hole made for this purpose on the internal face of the accessory to be used, preventing its movement while the source of high pressure remains active.
