Description
Válvula para funcionamiento automático de un extintor manual y perfeccionamiento de las existentes para conseguir este funcionamiento.Valve for automatic operation of a manual extinguisher and refinement of existing ones to get this operation
La presente invención se encuadra dentro de los elementos y dispositivos que forman parte de los extintores manuales de incendios.The present invention falls within the elements and devices that are part of fire extinguishers fire manuals.
Actualmente los extintores manuales constan, en general, de un recipiente metálico, al que se rosca una válvula cuya apertura es accionada 10 manualmente, una manguera con boquilla de proyección y un soporte. En el interior del recipiente se introduce un agente extintor y un gas propelente.Currently the manual extinguishers consist, in general, of a metal container, to which a valve whose thread is threaded opening is operated 10 manually, a hose with nozzle projection and a support. Inside the container is introduced an extinguishing agent and a propellant gas.
El conjunto cumple perfectamente su función cuando se utiliza, pero si no hay nadie para activarlo es completamente inútil contra el incendio y un peligro añadido por su posibilidad de explosión. Para evitar esta posibilidad, algunos extintores de alta presión, incorporan un sello de presión/temperatura que libera el gas propelente evitando de esta forma el peligro de explosión en estas situaciones.The set perfectly fulfills its function when it is used, but if there is no one to activate it it is completely useless against fire and a danger added by its possibility of explosion. To avoid this possibility, some high pressure extinguishers, incorporate a seal of pressure / temperature that releases the propellant gas avoiding this It forms the danger of explosion in these situations.
Son conocidas las patentes PO434168, E97101877, E96401032, W9734659 y otras, referentes a nuevas válvulas y dispositivos para los extintores, pero ninguna plantea la modificación o realización de una nueva válvula manual que permita además su funcionamiento automáticamente al estar el extintor en presencia de altas temperaturas o de otros parámetros de indicación de fuego, es decir que en esta situación no libere únicamente el gas propelente sino que funcione proyectando el producto extintor, como si se estuviera accionando su válvula manualmente.Patents PO434168, E97101877 are known, E96401032, W9734659 and others, referring to new valves and devices for fire extinguishers, but none raises the modification or realization of a new manual valve that allows also its operation automatically when the fire extinguisher is in presence of high temperatures or other indication parameters of fire, that is to say that in this situation not only release the propellant gas but work by projecting the extinguishing product, as if you were operating your valve manually.
Para ello la presente invención se centra en el perfeccionamiento y modificación de las actuales válvulas y el planteamiento de una nueva válvula que permite el funcionamiento propuesto.For this, the present invention focuses on the improvement and modification of the current valves and the approach of a new valve that allows operation proposed.
La presente invención plantea primeramente modificaciones que, sin interferir en el normal funcionamiento de las válvulas actuales, permiten además su funcionamiento automáticamente.The present invention raises first modifications that, without interfering with the normal operation of the current valves also allow its operation automatically.
Las válvulas actuales (fig.1) presentan un taladro axial (3), en la pared del cuello roscado (7) de la válvula para su unión al recipiente metálico, que comunica la parte superior del recipiente del extintor (8) (donde se encuentra el gas propelente) con el conducto (6) donde se aloja la válvula de seguridad, el manómetro o el sello de presión/temperatura en su caso, lo cual permite transmitir la presión del gas propelente a estos elementos.The current valves (fig. 1) have a axial bore (3), on the wall of the threaded neck (7) of the valve for its attachment to the metal container, which communicates the part top of the extinguisher vessel (8) (where the gas is located propellant) with the conduit (6) where the valve is housed safety, pressure gauge or pressure / temperature seal on your case, which allows the pressure of the propellant gas to be transmitted to This elements.
En todas las válvulas de extintores manuales, el mecanismo o pieza de cierre de presión (4) está situado en el cuello (7) que rosca la válvula al extintor con lo que todo elemento posterior a esa pieza (4) queda aislado de la presión interna del extintor. Por otro lado todos los extintores incorporan un tubo sonda (5) roscado internamente en el cuello de la válvula (7), el cual evita que, al accionar la válvula, escape el gas propelente sin empujar y arrastrar primeramente al producto extintor.In all manual extinguisher valves, the mechanism or pressure closure part (4) is located in the neck (7) that threads the valve to the extinguisher so that everything element after that part (4) is isolated from the pressure internal extinguisher On the other hand all extinguishers incorporate a probe tube (5) internally threaded into the neck of the valve (7), which prevents the gas from leaking when the valve is operated propellant without pushing and dragging the product first extinguisher.
Este tubo (5) sonda crea una zona aislada (8) para el gas propelente y un recorrido obligado de este para que, al abrir la pieza de cierre (4) de presión de la válvula, el gas en su salida empuje y arrastre al producto extintor. En el disparo automático del extintor, el gas seguirá también este recorrido para que el agente extintor sea arrastrado.This tube (5) probe creates an isolated zone (8) for the propellant gas and an obligatory route of this so that, at open the closing part (4) of the valve pressure, the gas in its exit push and drag to the extinguishing product. On the shot automatic extinguisher, the gas will also follow this route to that the extinguishing agent be dragged.
La presente invención se ilustra mediante los siguientes ejemplos de modificación y nueva válvula, los cuales no pretenden ser limitativos de su alcance.The present invention is illustrated by following examples of modification and new valve, which are not They are intended to be limiting of their scope.
Modificación que permite el funcionamiento automático (fig.2)Modification that allows operation automatic (fig. 2)

Modificación que puede conseguir el mismo resultado (fig.3):Modification you can get the same result (fig. 3):
- 1º-1st-
- acoplar un elemento en T en el extremo en que está roscado el manómetro (1) y situar el manómetro en un extremo de dicho elemento y en el otro extremo libre, el disparador o sello de presión/temperatura con la boquilla de proyecciónattach a T element at the end in which the manometer (1) is threaded and place the manometer in a end of said element and at the other free end, the trigger or pressure / temperature seal with the nozzle projection
- 2º-2nd-
- taladrar transversalmente el taladro (3) que une el espacio del manómetro (6) con el espacio del gas propelente (8) y sellar posteriormente las dos bocas (13 y 15) que dan a este espacio (8), dejando abierta solamente la boca (16) que comunica con el interior del tubo sondadrill the hole transversely (3) that joins the pressure gauge space (6) with the gas space propellant (8) and subsequently seal the two mouths (13 and 15) that give this space (8), leaving only the mouth open (16) that communicates with the inside of the probe tube
Sin ninguna modificación, una válvula convencional expulsará simplemente el gas propelente, al alcanzar el extintor cierta temperatura o presión, quedando el agente extintor en interior del recipiente del extintor y sin que esta expulsión de propelente tenga evidentemente ningún efecto contra el incendio.Without any modification, a valve conventional will simply expel the propellant gas, upon reaching the extinguisher certain temperature or pressure, leaving the agent extinguisher inside the extinguisher container and without Propellant expulsion obviously has no effect against the fire.
Las propias modificaciones, necesarias para conseguir este funcionamiento adicional de las válvulas actuales, conducen al diseño global de una válvula que permite este funcionamiento automático, aunando la normal utilidad de cierre de las actuales válvulas y las características del funcionamiento adicional propuesto.The modifications themselves, necessary for get this additional operation of the current valves, lead to the overall design of a valve that allows this automatic operation, combining the normal closing utility of Current valves and operating characteristics additional proposed.
La nueva válvula (fig. 4) puede mantener o no la conexión, mediante taladro (3), que une el espacio del recipiente con gas propelente (8) y el espacio (6) donde se sitúa el manómetro ya que su único fin es evitar que en la salida del agente extintor, al actuar el extintor manual o automáticamente, se pueda obstruir el conducto que permite al manómetro recibir la presión de gas propelente. Esta nueva válvula tiene el accionamiento de apertura (20) en sentido transversal al de acoplamiento (7) al recipiente del extintor, es decir según el eje de salida del gas del extintor a la manguera de proyección y con cierre a favor de presión.The new valve (fig. 4) can maintain or not the connection, by means of a drill (3), that joins the space of the container with propellant gas (8) and the space (6) where the pressure gauge is located since its sole purpose is to prevent the exit of the extinguishing agent, when the fire extinguisher is operated manually or automatically, it may clog the conduit that allows the pressure gauge to receive the gas pressure propellant This new valve has the opening drive (20) transverse to the coupling (7) to the container of the extinguisher, that is to say according to the output axis of the extinguisher gas to the projection hose and with closing in favor of pressure.
Esta disposición permite crear fácilmente, y con los mínimos mecanizados, un espacio conectado directamente con el tubo sonda y si se desea independiente o no del espacio del manómetro. Este espacio aloja: el mecanismo de cierre de la válvula y el de disparo automático, el manómetro si se desea, pudiendo estar conectado a una boquilla de proyección automática adecuada o a la propia boquilla del extintor si se sitúa el sello de presión/temperatura en un puenteo del cierre de la válvula o en el mismo cierre de la válvula.This arrangement allows you to easily create, and with the minimum mechanized, a space connected directly with the probe tube and if desired independent or not of the space of the manometer. This space houses: the valve closing mechanism and the automatic trigger, the pressure gauge if desired, being able to be connected to a suitable automatic projection nozzle or to the extinguisher nozzle itself if the seal of pressure / temperature in a valve closure bypass or in the Same valve closure.
