Abstract:
A valve with a thread for screwing into the pressure vessel (12) of a fire extinguisher has a plastic valve body (14) provided with a metallic lining (30, 38) in the area of the thread (15) and of the surfaces which are constantly under pressure. The metallic lining is advantageously designed as a one-piece, cup-shaped metal jacket (30, 38) set onto the end of the plastic body (14) which is screwed into the pressure vessel (12). The thread (15) is advantageously rolled into the metal jacket (30, 38). In a preferred embodiment, a spring-tube manometer (60) is set into the plastic body (14) and a metallic connection pipe (66) tightly extends through the inner metal jacket (30, 38). The metallic lining (30, 38) prevents creep in the plastic body (14) and thus ensures a perfect sealing under continuous pressure.

Abstract:
L'invention a trait à un robinet-détendeur (2) destiné à être raccordé à une bouteille de gaz. L'objectif de l'invention est d'assurer la fermeture et la mise en service du dispositif par des moyens simples et fiables à des pressions élevées. Un obturateur (14, 16) est commandé par une partie mobile (22) du détendeur, formant une chambre basse-pression (20) du dispositif. L'obturateur (14, 16) est soumis à un effort élastique (18) dans le sens de fermeture. Un ressort de travail (36) du détendeur agit sur la partie mobile (22) dans le sens de l'ouverture. Un organe de commande rotatif (38) travaillant sur moins d'un tour permet de mettre en compression le ressort de travail (36) en position de mise en service du dispositif (2). En position de fermeture, le plateau (44) du poussoir de l'organe de commande est à distance du ressort de travail (36).
Abstract:
The present invention relates to a gas container valve having improved excess flow prevention and gas-tightness. In particular, the gas container valve may block an excess flow when the excess flow occurs at one side of the gas container valve, and may be further provided with an excess flow prevention valve through which only a small amount of gas leaks. Thus, the gas container valve may prevent gas from leaking by means of a damaged hose or may prevent a person-induced gas leakage from occurring to improve safety, thereby enhancing product competitiveness. The gas container valve includes: a valve body disposed on one end of a gas container in which liquefied petroleum gas or liquefied natural gas is stored, the valve body having a discharge hole therein; an opening/closing unit disposed on the discharge hole of the valve body to open or close the discharge hole, to thereby prevent gas from being discharged or filled and the gas from leaking; a safety valve disposed on one side of the valve body; and a handle unit disposed on an upper portion of the valve body to open or close the opening/closing unit through a user's manipulation. The opening/closing unit (20) includes an excess flow blocking valve (250) for blocking the opening/closing unit (20), when a discharge pressure of gas discharged from the gas container is higher than a rated discharge pressure due to the damage of the hose or force exerted by a person, to slowly discharge the gas, thereby improving safety. Also, first and second blocking walls (14, 16) are successively disposed on the discharge hole (12) of the valve body (10). The opening/closing unit (20) further includes a first check spindle (210) including a first packing (212) for sealing the first blocking wall (14) and a second check spindle (220) including a second packing (122) for sealing the second blocking wall (16).

Abstract:
The electromechanical regulator for passenger oxygen is a hybrid oxygen regulator that provides for electronic or mechanical regulation of oxygen flow. The electronic portion of the regulator consists of an inlet solenoid valve, an outlet solenoid valve, a cabin pressure transducer, a regulated output transducer and a PID based controller, and the solenoid valves are normally biased so that in the event of an electronic system failure or a power supply failure the system will automatically revert to mechanical operation.
Abstract:
A gas cylinder dispensing valve (1) having an internal flow path provided with a pressure regulator (19). A biased isolation valve (96) is provided within the flow path between the pressure regulator (24) and a gas inlet (18) of the valve (1) and a flow control valve (152) is provided within the flow path between the pressure regulator (24) and a gas outlet (14) to discharge the gas. Both isolation valve (96) and the flow control valve (152) can be manipulated by a single control knob (26) which when set in an off position closes the isolation valve (96). The control knob (26) can be rotated from the off position to select discrete, calibrated flow rates or an auxiliary position in which gas may be dispensed at a regulated pressure from an auxiliary outlet port (50).
Abstract:
A valve (10) for a pressurized canister (12) includes a housing having a central aperture (16) extending therethrough, a first set of external threads (18), and a second set of external threads (23). A sealing member is positioned in an axially outward end of the central aperture and is axially moveable. A first spring (30) biases the pin axially outward. An axially slidable member (52) is received and axially movable in the central aperture. A second spring (58) biases the axially slidable member outwardly. A threaded member (74) in an aperture in the housing engages the axially slidable member. Each of a plurality of radially moveable members (68) is positioned in an aperture in the housing and is radially moveable between a lip on the aperture and the second spring. An exterior surface of an inner end of the axially slidable member engages and forces each radially moveable member into contact with the lip when the threaded member is tightened.
Abstract:
The invention relates to a plug valve for liquefied gas containers and, more specifically, to plug valves of the type that are installed in the openings of liquefied gas containers for industrial and domestic use. The inventive valve closes automatically and opens with the aid of a push device which is built into a control valve which, together with a pressure-reducing valve, controls the flow of gas supplied to a gas-consuming appliance. According to the invention, the ball (23) of the ball-plug (3) is equipped with a slide appendage (24) which is perpendicular to the sealing plane and which is provided with a straight section such as to prevent the rotation thereof. The aforementioned slide is disposed in line with, and can slide in relation to, a guide hole (25) which is provided in the base (22) of the spring body (6) of the support case (2).
