Description

закрытии затвора рычажный усилитель не задействовал, усилие закрыти  задвижки значительно меньше чем усилие открыти .when closing the gate, the lever amplifier did not activate; the effort to close the gate valve is much less than the effort to open.

Предмет изобретени Subject invention

Пневмогидропривод дл  клиновых задвижек с рычажным усилителем, св занным соA pneumatic actuator for wedge gate valves with lever booster connected to

штоком задвижки, отличаюшийс  тем, что, с целью увеличени  кратности усилий ири открывании и закрывании задвижки, рычажный усилитель выполнен из подвижной опоры, насаженной на шток и рычага, вставленного в поперечное отверстие штока, причем короткое плечо рычага кинематически св зано с подвижной опорой, а длинное - с поршнем.a valve stem, characterized in that, in order to increase the multiplicity of efforts to open and close the valve, the lever amplifier is made of a movable support mounted on a rod and a lever inserted into the transverse hole of the rod, and the short lever arm is kinematically connected with the movable support, long - with a piston.
