Abstract:
A pressure regulator (1) comprises a high pressure chamber (2) accommodated in a high pressure housing (3) and a low pressure chamber (4) accommodated in a low pressure housing (5). The chambers (2, 4) can communicate with each other via a controllable valve (6). The maximum pressure level in the high pressure chamber (2) against which the high pressure housing (3) is resistant is higher than the maximum pressure level in the low pressure chamber (4) against which the low pressure housing (5) is resistant. The low pressure chamber (4) is provided with a release valve (3, 18; 19-21) which opens to the outside at a predetermined pressure level in the low pressure chamber (4). The high pressure housing (3) is resiliently connected to and movable with respect to the low pressure housing (5) such that the high pressure housing (3) displaces with respect to the low pressure housing (5) upon a pressure change in the low pressure chamber (4).
Abstract:
L' invention a trait à un dispositif de vanne du type robinet bouteille comprenant un raccord (11) de remplissage en liaison directe avec l'entrée (2) du robinet sans passer par le dispositif de fermeture (4, 8) du robinet. Un élément filtrant (12) est disposé dans une chambre à l'intersection entre l'entrée du robinet et le dispositif de fermeture du robinet. Ceci permet un agencement optimal du filtre du point de vue accessibilité et aussi du point de vue écoulement du gaz. En effet, le filtre est agencé dans la chambre de sorte à filtrer le flux de gaz allant vers la sortie (3) du robinet via le dispositif de fermeture, protégeant ainsi ce dernier, et aussi de sorte à ne pas filtrer le flux de gaz de remplissage allant du connecteur de remplissage du robinet vers l'entrée.

Organe de contrôle du remplissage et/ou du soutirage d'un gaz sous pression destiné à être monté dans un orifice d'un réservoir (1 ), comprenant un corps (21 ) pourvu d'au moins un dispositif (8) de contrôle de la circulation du gaz disposé entre une première extrémité comprenant un orifice (31 ) formant une entrée et/ou une sortie pour le gaz vis-à-vis du réservoir et une seconde extrémité destinée à communiquer avec l'intérieur du réservoir, l'organe de contrôle comprenant en outre un dispositif (5) d'échappement de gaz de sécurité pour évacuer le gaz hors du réservoir en cas de situation à risque et comprenant un canal ou circuit d'échappement de gaz (215, 213, 212, 211 , 31 ) s'étendant entre une première extrémité (215) destinée à communiquer avec le gaz sous pression du réservoir et une seconde extrémité (31 ) destinée à communiquer avec un circuit utilisateur ou avec l'atmosphère, le circuit d'échappement étant obturé ou non en fonction de l'état d'un élément de sécurité (52), caractérisé en ce que la seconde extrémité du circuit d'échappement (215, 213, 212, 211 , 31 ) de gaz coïncide avec l'orifice (31 ) de l'organe de contrôle formant une entrée et/ou une sortie pour le gaz.
Abstract:
A controlled pressure release valve controls the gas flow in high-pressure systems. The valve includes a valve body, a slidable spool, a primary flow passage, a first and second chamber, a first and second spring, a first and second passages, and a valve actuator. The valve body has a gas inlet and a gas outlet and houses the slidable spool. The slidable spool has a first end and a second end, and is slidable between a first position and a second position. The primary flow passage connects the gas inlet and the gas outlet and increases with lineal movement of the slidable spool. The first chamber is located adjacent the first end of the slidable spool and a second chamber is located adjacent the second end of the slidable spool. The sliding spool is biased toward the first position by a gas pressure applied by the second chamber and the second spring.
Abstract:
A regulator device includes a first valve member and a second valve member disposed within a housing of the device. The first valve member regulates the pressure of fluid exiting the device, and the second valve member is biased to a closed position and is opened by manipulation of an actuator. A sealing element is connected at the housing outlet and has a transverse cross-sectional dimension that decreases from an inlet of the sealing element to an outlet of the sealing element. In addition, a guard is provided that extends around a periphery of the actuator and includes a cut-out section to permit easy access to the actuator during use of the device.
Abstract:
The present invention relates to a pressure detection LPG tank valve capable of preventing safety accident by gas leakage in such a manner that LPG leaked to a pressure controller is automatically disconnected in the case that a part of LPG discharged to a pressure controller is leaked when a pressure controller is abnormally connected with a valve body or an error occurs in a pressure controller. The pressure detection LPG tank valve includes a first space part, a gas inlet hole formed in a lateral wall of a shielding member, a piston moving down by a pressure of gas inputted through the gas inlet hole, a shielding plate, a transfer hole formed in the valve body, and a check valve operating by a pressurizing pin.
Abstract:
Le clapet permet le remplissage sous pression d'un gaz à l'intérieur d'une bouteille et le vidage de cette dernière tout en assurant un. degré de pureté suffisant du gaz. Le clapet se monte à l'intérieur de la bouteille (20). Il présente des premiers orifices de remplissage (30) latéraux s'ouvrant par la pression du gaz de remplissage en poussant le premier piston (3) dans la position de remplissage. Le vidage s'effectue en ouvrant un robinet externe (12), les orifices latéraux (30) étant rebouchés par la remontée du premier piston (3), grâce au premier ressort (5). Un deuxième piston (4) ouvre alors l'orifice de vidage (31) qui est complété par un filtre (7).
Abstract:
The present invention relates to a container valve for liquefied petroleum gas (LPG) and, more particularly, to a gas container valve capable of previously preventing a dangerous situation by making a rear pressure of the container and the inner pressure of the container the same at the time of opening the container. The valve for the LPG according to the present invention comprises : a valve body in which a gas flow hole, a main gas guide hole and an exhaust guide hole are provided; a handle having an opening/closing member for selectively opening and closing the main gas guide hole; a pressure controller, for making a rear pressure of the valve and an inner pressure of the container the same, having a gas exhaust hole to exhaust a very small amount of the gas and a gas exhaust blocking member to control a gas exhaust; and an overflow gas controller for opening/closing the main gas guide hole according to a movement of the pressure controller.
Abstract:
The invention concerns an expansion valve comprising a gas regulating body (2), a quick-fit device on the gas bottle neck comprising a lock collar (14) transversely mobile relative to the axis of the cylinder neck and designed to be urged to press behind a shoulder thereof, and a valve (42, 47) actuating a flap gate (28) allowing or preventing gas from passing through to the high pressure chamber of the gas regulator. The gas regulator body (2) comprises a tubular skirt (13) used for mounting a subassembly including two superposed rings (18, 15) equipped with two concentric skirts (19, 26) defining an annular space for engaging the bottle neck, the inner skirt (26) containing a closure gate (28) of the valve, the two rings (18, 25) defining between them a space for housing and guiding the lock ring (14) which is provided with a tab used for mounting the valve lever (47).
