Title (EN) ELECTROMECHANICAL-LINKAGE HYDRAULIC-CONTROL GATE VALVE DRIVER
(FR) PILOTE DE ROBINET-VANNE À COMMANDE HYDRAULIQUE À LIAISON ÉLECTROMÉCANIQUE
(ZH) 一种机电联动液控闸阀驱动器
Abstract:
(EN) An electromechanical-linkage hydraulic-control gate valve driver comprises an explosion-proof motor (2), a hydraulic-control gate valve (1), and an actuator frame (3), and is additionally provided with a hand-cranked speed increasing gearbox assembly (4) and a bidirectional throttling valve (5). The driver can drive a motor in emergency working conditions, such as repair and power failure working conditions, by means of a hand-cranked speed increasing gearbox, so as to control the opening and closing of a gate valve. In addition, a hydraulic system adjusts the speeds for the opening and closing states by using a bidirectional throttling technology, so as to effectively remove a water hammer.
(FR) L'invention concerne un pilote de robinet-vanne à commande hydraulique à liaison électromécanique comprenant un moteur antidéflagrant (2), un robinet-vanne à commande hydraulique (1), et une structure d'actionneur (3), et est en outre pourvu d'un ensemble boîte à engrenages d'augmentation de vitesse à actionnement manuel (4) et d'une soupape d'étranglement bidirectionnelle (5). Le pilote peut entraîner un moteur dans des conditions de fonctionnement d'urgence, telles que des conditions de fonctionnement en réparation et en panne d'alimentation, au moyen d'une boîte à engrenages d'augmentation de vitesse à actionnement manuel, de manière à commander l'ouverture et la fermeture d'un robinet-vanne. De plus, un système hydraulique règle les vitesses pour les états d'ouverture et de fermeture à l'aide d'une technologie d'étranglement bidirectionnelle, de façon à supprimer efficacement un coup de bélier.
(ZH) 一种机电联动液控闸阀驱动器,包括防爆电机(2)、液控闸阀(1)及执行器机架(3),并增设有手摇增速箱总成(4)和双向节流阀(5)。上述驱动器可以通过手摇增速箱的方式,在检修和断电等的应急工况下驱动电机,从而控制闸阀的启闭;同时液压系统采用双向节流技术对开启和关闭两种状态分别进行速度调节,可以有效消除水锤。
