L’inventivité de ce produit consiste en une bague de sécurité, qui autorise la fermeture des mâchoires sur le robinet lorsque celle-ci est approchée correctement sur le robinet et recule de manière raisonnable avec l’about. Le système comporte aussi une douille de verrouillage, dont le mouvement est assisté par un ressort, empêchant l’ouverture inopinée ou non des mâchoires mobiles pendant la mise en position de la prise de remplissage. Enfin, l’innovation propose un troisième niveau de sécurité pendant le remplissage, bloquant les mâchoires contre la douille, empêchant alors toute manipulation de celle-ci, et ce dès le début du remplissage. La figure 2 est désignée pour accompagner l’abrégé de l’invention.Safety system for quick-connect sockets for filling gas cylinders, mainly air gas, at high pressure, from 200 bar, for cylinders with a male tap, and usable in the medical and food fields . The inventiveness of this product consists of a safety ring, which allows the jaws to close on the tap when it is approached correctly on the tap and moves back reasonably with the plug. The system also includes a locking sleeve, the movement of which is assisted by a spring, preventing the opening, unexpected or not, of the mobile jaws during the positioning of the filling socket. Finally, the innovation offers a third level of safety during filling, blocking the jaws against the socket, thus preventing any manipulation of the latter, and this from the start of filling. Figure 2 is designated to accompany the abstract of the invention.

Description

Système de sécurité pour prise de remplissage à connexion rapide pour gaz à haute pression.Safety system for quick connection filling socket for high pressure gas.

Domaine technique de l’inventionTechnical field of the invention

L’invention concerne un système de sécurité, notamment dans le cas de systèmes de serrage ou de coupleurs à fermeture rapide, destiné au remplissage de bouteilles de gaz, principalement gaz de l’air, sous haute pression, à partir de 200 bars, et plus particulièrement pour des bouteilles disposant d’un robinet mâle.The invention relates to a safety system, in particular in the case of clamping systems or quick-closing couplers, intended for filling gas bottles, mainly air gases, under high pressure, from 200 bars, and more particularly for bottles with a male tap.

Problème techniqueTechnical problem

La prise à fermeture rapide présente aujourd’hui sur le marché dans le domaine d’application présenté ci-dessus permet aux opérateurs de gagner un temps non négligeable, par rapport aux prises vissées, mais présentes des déficiences de sécurité inhérents à leur conception. Le risque principal réside donc dans le décrochement de la prise lors du remplissage de la bouteille si la prise a mal été positionnée par l’opérateur. Cet arrachement soudain de la prise peut causer des dégâts physiques et matériels importants, notamment avec l’effet « coup de fouet », dû au gaz s’échappant sous pression, voire une combustion instantanée dans le cas de remplissage d’oxygène. Par conséquent, le but de cette invention est de proposer un système de verrouillage de la prise pour coupler la prise sur le robinet, que l’opérateur se voit obligé d’effectuer pour effectuer l’opération de remplissage.The quick-closing socket present on the market today in the field of application presented above allows operators to save a significant amount of time, compared to screwed sockets, but present safety deficiencies inherent in their design. The main risk therefore lies in the disconnection of the plug when filling the bottle if the plug has been incorrectly positioned by the operator. This sudden tearing of the plug can cause significant physical and material damage, in particular with the "whiplash" effect, due to the gas escaping under pressure, or even instantaneous combustion in the case of oxygen filling. Therefore, the object of this invention is to provide a plug locking system for coupling the plug to the tap, which the operator is obliged to perform in order to perform the filling operation.

De plus, la prise pouvant être utilisée dans certains cas dans le domaine médical ou alimentaire, les composants en contact avec le gaz doivent être fabriqués dans des matériaux en adéquation avec les contraintes que représentent ces domaines.In addition, the socket can be used in certain cases in the medical or food field, the components in contact with the gas must be manufactured in materials in line with the constraints represented by these fields.

Solution techniqueTechnical solution

L’invention consiste en une bague de sécurité placée entre l’about et les mâchoires mobiles. En position de repos, la bague de sécurité est placée de manière à empêcher les mouvements radiaux des mâchoires mobiles, et permet donc le passage de la prise pour approcher le robinet. Lorsque l’about entre en contact avec la face du robinet, celui-ci recule en même temps que la bague de sécurité. Le recul de la bague de sécurité permet alors de libérer le mouvement radial des mâchoires mobiles qui peuvent donc accrocher sur les filets extérieurs du robinet. La douille de verrouillage est guidée axialement dans une rainure du corps HP à l’aide d’une vis placée sur la douille et assistée d’un ressort pour faciliter la tâche de l’opérateur. L’avancement de la douille a alors pour effet de plaquer les mâchoires vers le filetage extérieur du robinet et ainsi bloquer l’ouverture des mâchoires, rendant alors impossible une ouverture inopinée. Un verrouillage de la douille doit être effectué en lui imposant une rotation d’un quart de tour pour, confirmé par une gravure sur la douille. Un troisième niveau de sécurité, nommé autobloquant, se déclenche dès les premiers bars de remplissage. Le robinet a naturellement tendance à vouloir reculer sous l’effet de la pression mais est retenu par les mâchoires. L’angle d’incidence du filetage des mâchoires permet alors un léger glissement vers l’extérieur, et donc de plaquer l’extérieur des mâchoires contre la douille, ce qui a pour effet de bloquer la douille en position. L’opérateur ne peut alors plus actionner la douille intentionnellement ou par erreur. A contrario, si la prise est mal positionnée sur le robinet, la bague de sécurité ne peut pas suffisamment reculer et les mâchoires ne s'accrochent pas sur le robinet. Il est alors impossible d’actionner la douille et donc de bloquer les mâchoires sur le robinet.The invention consists of a safety ring placed between the end piece and the movable jaws. In the rest position, the safety ring is placed in such a way as to prevent the radial movements of the mobile jaws, and therefore allows the passage of the socket to approach the valve. When the butt comes into contact with the face of the valve, it recoils together with the safety ring. The retreat of the safety ring then makes it possible to release the radial movement of the mobile jaws which can therefore catch on the external threads of the valve. The locking sleeve is guided axially in a groove of the HP body by means of a screw placed on the sleeve and assisted by a spring to facilitate the task of the operator. The advancement of the sleeve then has the effect of pressing the jaws towards the external thread of the valve and thus blocking the opening of the jaws, thus making an unexpected opening impossible. The sleeve must be locked by imposing a rotation of a quarter turn, confirmed by an engraving on the sleeve. A third level of safety, called self-locking, is triggered from the first filling bars. The valve naturally tends to want to move back under the effect of pressure but is held back by the jaws. The angle of incidence of the thread of the jaws then allows a slight sliding outwards, and therefore to press the outside of the jaws against the sleeve, which has the effect of locking the sleeve in position. The operator can then no longer actuate the socket intentionally or by mistake. On the other hand, if the socket is incorrectly positioned on the tap, the safety ring cannot move back sufficiently and the jaws do not catch on the tap. It is then impossible to operate the sleeve and therefore to block the jaws on the valve.

Une fois que la prise est bien positionnée sur le robinet, l’opération de remplissage peut être effectuée. Lorsque le remplissage est terminé, il suffit alors à l’opérateur de pivoter la douille d’un quart de tour puis de la reculer, ce qui a pour conséquence de libérer les mâchoires mobiles du filetage du robinet. La prise peut alors être retirée, l’about et la bague de sécurité reviennent à leur position d’origine.Once the plug is correctly positioned on the tap, the filling operation can be carried out. When filling is complete, the operator simply has to pivot the sleeve a quarter turn then move it back, which has the effect of freeing the mobile jaws from the tap thread. The plug can then be removed, the butt and safety ring return to their original position.

La prise à fermeture rapide peut, dans certains cas, être utilisée dans le cadre de remplissage de bouteille à destination du domaine médical et/ou alimentaire. Il faut donc que les pièces composant le système de sécurité qui sont en contact avec le gaz soient compatibles avec ces gaz. Dans le cas présent, une seule pièce est concernée par cette problématique. Il s’agit de la bague de sécurité. Nous avons choisi de concevoir cette bague en acier Inoxydable de type 316L.The quick-closing plug can, in certain cases, be used for filling bottles intended for the medical and/or food sectors. It is therefore necessary that the parts making up the safety system which are in contact with the gas are compatible with these gases. In this case, only one part is affected by this problem. This is the safety ring. We have chosen to design this ring in 316L stainless steel.
