Description

Robinet pour gaz haute pression actionné par un levier adaptable à différentes têtes de bouteilles High pressure gas valve operated by a lever adaptable to different cylinder heads
Il existe, d'une part des robinets à détendeurs intégrés qui comportent un levier permettant de commander l'ouverture ou la fermeture de la vanne qui autorise ou interdit le débit du gaz contenu dans la bouteille vers l'extérieur et, d'autre part, des robinets sans détendeur, utilisables dans une centrale de détente par exemple, mais avec levier de commande et en option un manomètre permettant de lire la pression du gaz contenu dans la bouteille.There are, on the one hand, valves with integrated regulators which include a lever making it possible to control the opening or the closing of the valve which authorizes or prohibits the flow of the gas contained in the bottle towards the outside and, on the other hand , taps without regulator, usable in a pressure reduction unit for example, but with control lever and optionally a pressure gauge allowing to read the pressure of the gas contained in the bottle.
Si un robinet à détendeur intégré justifie l'utilisation d'un chapeau ou capotage de protection spécifique, protégeant les organes fragiles, laissant accès à la vanne (Marche / Arrêt) et au dispositif de réglage de la pression de détente, ne gênant pas la lecture des manomètres et/ou permettant le montage d'un sceau de garantie, un simple robinet, destiné à remplacer des robinets à volant par exemple, ne justifie pas réellement le remplacement coûteux de chapeaux existants.If a valve with integrated regulator justifies the use of a specific protective cap or cover, protecting fragile parts, allowing access to the valve (On / Off) and to the device for regulating the trigger pressure, not hampering the reading the pressure gauges and / or allowing the mounting of a guarantee seal, a simple tap, intended to replace steering wheel taps for example, does not really justify the costly replacement of existing caps.
Dans une utilisation classique de poste oxyacétylénique, une bouteille d'oxygène et une bouteille d'acétylène sont regroupées dans un chariot ou contre un mur et fixées par une chaîne, la lecture du manomètre, la fixation du détendeur, le réglage du détendeur et la lecture des manomètres du détendeur doivent se faire sans gène et sans risques.In a conventional use of an oxy-acetylene station, an oxygen cylinder and an acetylene cylinder are grouped in a cart or against a wall and fixed by a chain, reading the pressure gauge, fixing the regulator, regulating the regulator and The pressure regulator pressure gauges must be read without hindrance and without risk.
Or, la bouteille d'oxygène est généralement plus haute que celle d'acétylène et il en résulte que l'accès au robinet de la bouteille d'acétylène est difficile du côté de la bouteille d'oxygène et impossible du côté du mur. Une contrainte supplémentaire réside dans le fait qu'il est souhaitable pour des raisons d'économie d'échelle en production, que les robinets des différentes bouteilles soient aussi semblables que possible ce qui conduit à la standardisation de leurs composants.However, the oxygen cylinder is generally higher than that of acetylene and it follows that access to the valve of the acetylene cylinder is difficult on the side of the oxygen cylinder and impossible on the side of the wall. An additional constraint resides in the fact that it is desirable for reasons of economy of scale in production, that the valves of the different bottles are as similar as possible, which leads to the standardization of their components.
Dans l'utilisation également classique de bouteilles réunies par une rampe et alimentant par exemple un dispositif de détente centralisé, les bouteilles sont placées côte à côte, contre un mur et il doit être possible de monter et démonter les flexibles de raccordement, actionner le levier, lire le manomètre du robinet, sans être gêné ni par les chapeaux ni par les bouteilles voisines.In the also conventional use of bottles joined by a ramp and supplying for example a centralized expansion device, the bottles are placed side by side, against a wall and it must be possible to mount and dismount the connection hoses, actuate the lever , read the tap pressure gauge, without being bothered either by the caps or by neighboring bottles.
Les robinets sont généralement conçus pour être usinés sur des machines transfert dans les quelles il est préférable que tous les axes soient orthogonaux. Cette disposition présente l'avantage d'être plus économique à la production mais limite les possibilités d'implantation des composants. Les robinets d'extincteurs qui sont communément équipés d'un manomètre et d'un levier, ne sont pas couverts d'un chapeau et ne reçoivent pas de détendeur Dans le domaine des gaz industriels, il n'existe pas de robinets à levier.The valves are generally designed to be machined on transfer machines in which it is preferable that all the axes are orthogonal. This arrangement has the advantage of being more economical in production but limits the possibilities of installing the components. Fire extinguisher valves, which are commonly equipped with a pressure gauge and a lever, are not covered with a cap and do not receive a regulator. In the field of industrial gases, there are no lever valves.
Le problème qui s'est posé était donc de trouver une organisation des composants d'un robinet à levier et à manomètre compatible avec des chapeaux préexistants sur les bouteilles.The problem that arose was therefore to find an organization of the components of a lever valve and pressure gauge compatible with preexisting caps on the bottles.
L'ensemble robinet /chapeau devant rester sûr et commode tant pendant le transport et le remplissage de la bouteille que pendant l'utilisation qui peut conduire à regrouper plusieurs bouteilles côte à côte et souvent le long d'un mur.The tap / cap assembly must remain safe and convenient both during transport and filling of the bottle and during use which can lead to grouping several bottles side by side and often along a wall.
La solution de l'invention consiste en un robinet à levier adaptable à différents chapeaux de bouteilles dont les dispositions relatives des composants accessibles ou visibles par l'utilisateur, à savoir le levier, le manomètre et le raccord d'entrée/ sortie, résolvent le problème susmentionné.The solution of the invention consists of a lever tap adaptable to different bottle caps, the relative arrangements of the components accessible or visible to the user, namely the lever, the pressure gauge and the inlet / outlet connection, resolve the above problem.

The lever 2 has two flats 22 and 23 which can come to bear on a pusher 3 applied against the lever 2 by a spring 31. The pusher 3 is integral with a rod 32. When the lever 2 is in the rest or stop position, shown in Figures 1 and 2, the assembly formed by the pusher 3 and the rod 32 is in the position close to the axis (YY). By rotating the lever 2 so that the surface 23 comes into contact with the pusher 3, the assembly 3, 32 is caused to move which, deviating from the axis (YY) comes into contact, then moves the valve 33 which leaves its seat 34 and authorizes the passage of the gas through the part 37, from the interior of the bottle to the connector 4. A boss 41 of the body 1, drilled and tapped makes it possible to fix and supply the pressure gauge 5, which indicates the pressure of the gas circulating in the valve body 1, therefore also contained in the bottle.
Pour pouvoir entrer dans un chapeau, l'ensemble doit passer dans un cercle d'un diamètre inférieur à 75 mm et être contenu dans un cylindre centré sur l'axe de la bouteille de diamètre inférieur au diamètre intérieur du chapeau soit 88 mm et sa hauteur H4 ne doit pas dépasser 110 mm. La double condition des diamètres 75 mm et 88 mm résulte du fait qu'il est possible d'imaginer un robinet tel que certaines parties s'inscrivent dans un cercle de diamètre 75 mm dont le centre ne se trouve pas dans l'axe de la bouteille ; un tel robinet ne peut être couvert que partiellement par le chapeau si la distance entre le centre du dit cercle de 75 mm et l'axe de la bouteille est supérieure à 13 mm.To be able to enter a hat, the assembly must pass in a circle with a diameter less than 75 mm and be contained in a cylinder centered on the axis of the bottle with a diameter less than the inside diameter of the hat, ie 88 mm and its height H4 must not exceed 110 mm. The double condition of the diameters 75 mm and 88 mm results from the fact that it is possible to imagine a tap such that certain parts are part of a circle of diameter 75 mm whose center is not located in the axis of the bottle; such a valve can only be partially covered by the cap if the distance between the center of said circle of 75 mm and the axis of the bottle is more than 13 mm.
Pour permettre une utilisation efficace du levier 2, l'accès au raccord 4 et la lecture du manomètre 5 lorsque le robinet est protégé par un capotage, les angles et distances suivantes ont été déterminés après de nombreux essais effectués tant dans des conditions d'utilisation (montage d'un détendeur sur le raccord 4 sans heurter le manomètre 5 avec la queue du détendeur, manœuvre du levier, réglage du détendeur) avec différents détendeurs, de remplissage et de transport, avec des opérateurs de différentes tailles droitiers et gauchers.To allow efficient use of lever 2, access to fitting 4 and reading of pressure gauge 5 when the valve is protected by a cover, the following angles and distances have been determined after numerous tests carried out both under conditions of use (mounting a regulator on connection 4 without hitting the pressure gauge 5 with the tail of the regulator, operating the lever, regulating the regulator) with different regulators, filling and transport, with operators of different right and left-handed sizes.
Les dimensionnements possibles répondant aux critères fixés dans le cadre de l'invention sont donnés dans les tableaux ci-après.The possible sizes meeting the criteria set in the context of the invention are given in the tables below.
