Abstract

Patente de Invenção "CONJUNTO DE TAMPA PARA VáLVULA DE COMPORTA E VáLVULA". é apresentado um conjunto de tampa de válvula de comporta, que inclui um redutor de velocidade embutido. O conjunto de tampa inclui uma carcaça de tampa, que é presa a um corpo da válvula de comporta, com a carcaça de tampa tendo um furo central através dela e uma câmara ao longo do furo central. Uma haste de válvula é posicionada, de modo a poder mover-se, dentro do furo central e acoplada à comporta de válvula e ao acionador de válvula. Um pistão é alojado, de modo a poder deslizar, sobre a haste de válvula e é posicionado dentro da câmara, o pistão incluindo pelo menos um orifício de amortecimento através dele. Um flange é preso à haste de válvula de modo a encostar no pistão de modo a mover o pistão quando a haste de válvula é movida entre a posição de fechamento e a posição de abertura. Além disto, é apresentada uma mola para mover de modo independente o pistão até a posição originária quando a haste de válvula é movida entre a posição de abertura e a posição de fechamento.Invention Patent "COVER SET FOR BEAM VALVE AND VALVE". a gate valve cover assembly is included, which includes a built-in speed reducer. The cover assembly includes a cover housing, which is attached to a gate valve body, with the cover housing having a central hole through it and a chamber along the central hole. A valve stem is positioned so that it can move, inside the central hole and attached to the valve gate and the valve driver. A piston is housed, in order to be able to slide, on the valve stem and is positioned inside the chamber, the piston including at least one damping hole through it. A flange is attached to the valve stem in order to touch the piston in order to move the piston when the valve stem is moved between the closed position and the open position. In addition, a spring is provided to independently move the piston to the original position when the valve stem is moved between the opening position and the closing position.
