Abstract
Задвижка с дублирующим приводом, содержащая шибер со шпинделем, основной пневмо- или гидропривод и дублирующий ручной привод с маховиком, отличающаяся тем, что на верхней цилиндрической части шпинделя выполнена резьба, взаимодействующая с резьбой на внутренней поверхности ходовой гайки, пропущенной через уплотнитель в крышке основного привода, установленной в поворотной втулке с донышком и сопрягаемой с ней поверхностью своих внешних граней или шпоночным соединением, причем указанная втулка соединена с маховиком ручного привода и установлена в подшипниках на крышке основного привода, поршень основного привода установлен на шпинделе с возможностью независимого осевого перемещения последнего для закрытия шибера под действием механического привода, а на шпинделе выполнен уступ, к которому ходовой гайкой прижимается поршень для обеспечения осевого перемещения шпинделя под действием основного привода, при этом в открытом положении шибера ходовая гайка торцами взаимодействует с поршнем и донышком втулки. Gate valve with a backup actuator, containing a gate with a spindle, a main pneumatic or hydraulic actuator and a backup manual actuator with a flywheel, characterized in that a thread is made on the upper cylindrical part of the spindle, interacting with a thread on the inner surface of the travel nut, passed through a seal in the cover of the main actuator installed in the rotary sleeve with a bottom and the surface of its external faces mating with it or with a key connection, and this sleeve is connected to the handwheel of the manual drive and mounted in bearings on the cover of the main drive, the piston of the main drive is mounted on the spindle with the possibility of independent axial movement of the latter to close the gate under the action of the mechanical drive, and a step is made on the spindle, to which the piston is pressed against the spindle nut to ensure axial movement of the spindle under the action of the main drive, while in the open position of the slide, the end nut interacts with the piston and the bottom of the sleeve.
