Title
(EN) A GAS CONTROL VALVE
(FR) SOUPAPE DE COMMANDE DE GAZ
(ZH) 一种燃气阀
Abstract
(EN)
A gas control valve includes an inlet; a depressing tube communicating with the inlet wherein there is a valve port with a seal ring; a membrane valve body having a top half shell, a bottom half shell and a resilient membrane between the top half shell and the bottom half shell, the membrane defining a gas delivery chamber at the bottom half shell and a spring chamber with a pressing spring at the top half shell; an outlet communicating with the gas delivery chamber; a pin passing through the membrane and fixed thereon; a valve core having a valve head located ahead of the port and a valve rod extending through the port into the gas delivery chamber; a transmission device linking the pin with the valve rod for transforming up-down movement of the pin into axial movement of the valve rod; and a starting passage having an open-shut switch for communicating the inlet with the gas delivery chamber when starting the gas control valve. The gas control valve can prevent gas from leaking out without electromagnetic effect.

L'invention concerne une soupape de commande de gaz qui comprend une entrée ; un tube de dépression communiquant avec l'entrée, un orifice de soupape pourvu d'un anneau d'étanchéité s'y trouvant ; un corps de soupape à membrane ayant une demi-enveloppe supérieure, une demi-enveloppe inférieure et une membrane élastique entre la demi-enveloppe supérieure et la demi-enveloppe inférieure, la membrane définissant une chambre de distribution de gaz au niveau de la demi-enveloppe inférieure et une chambre de ressort pourvue d'un ressort de compression au niveau de la demi-enveloppe supérieure ; une sortie communiquant avec la chambre de distribution de gaz ; une broche passant à travers la membrane et fixée dessus ; un noyau de soupape ayant une culasse située en avant de l'orifice et une tige de soupape s'étendant à travers l'orifice dans la chambre de distribution de gaz ; un dispositif de transmission reliant la broche à la tige de soupape pour effectuer un déplacement vertical de la broche en un déplacement axial de la tige de soupape ; et un passage de démarrage ayant un commutateur d'ouverture-fermeture pour mettre en communication l'entrée et la chambre de distribution de gaz lors du démarrage de la soupape de commande de gaz. La soupape de commande de gaz peut empêcher du gaz de fuir à l'extérieur sans effet électromagnétique.
