Abstract

FIELD: valve production, valve control. SUBSTANCE: drive of rotary isolation members of pipelines has casing, rotation motor, reduce gear, screw pair, connecting link made in the form of double fork and secured to the casing using two supports, slide block placed between connection link forks and interacting through pivots with surfaces of connection link fork slots and two guide slots originated in the casing, as well as means of stopping the screw of the screw pair with the slide blocks in terminal positions. Screw pair nut is made in the form of a cylinder with axis being perpendicular to threaded opening, and placed so as to be rotated and have play in cylindrical space originated in the slide block. In so doing cylindrical space axis is perpendicular to the axis the pivots and screw axis are located along. EFFECT: lateral load free operation. 3 cl, 3 dwg

Изобретение относится к области арматуростроения и может быть использовано для управления запорными элементами трубопроводов большого диаметра. Использование изобретения позволяет обеспечить работу винта винтовой пары в отсутствии боковых нагрузок. Привод поворотных запорных элементов трубопроводов содержит корпус, двигатель вращения, редуктор, винтовую пару, кулису, выполненную в виде двойной вилки и закрепленную в корпусе на двух опорах, ползун, расположенный между вилками кулисы и взаимодействующий через цапфы с поверхностью пазов вилок кулисы и двух направляющих пазов, выполненных в корпусе, а также средства торможения винта винтовой пары при крайних положениях ползуна. Гайка винтовой пары выполнена в виде цилиндра, ось которого перпендикулярна резьбовому отверстию, и размещена с возможностью относительного поворота и осевого люфта в цилиндрической полости, выполненной в ползуне, при этом ось цилиндрической полости перпендикулярна оси, вдоль которой расположены цапфы и оси винта. 3 ил.The invention relates to the field of valve engineering and can be used to control the locking elements of large diameter pipelines. Using the invention allows for the operation of a screw of a screw pair in the absence of lateral loads. The drive of the rotary locking elements of the pipelines comprises a housing, a rotation motor, a reducer, a screw pair, a link, made in the form of a double fork and fixed in the housing on two supports, a slider located between the forks of the wings and interacting through the pins with the surface of the grooves of the forks of the wings and two guide grooves made in the housing, as well as means for braking the screw of the screw pair at the extreme positions of the slider. The nut of the screw pair is made in the form of a cylinder, the axis of which is perpendicular to the threaded hole, and placed with the possibility of relative rotation and axial play in a cylindrical cavity made in the slider, while the axis of the cylindrical cavity is perpendicular to the axis along which the axles and axis of the screw are located. 3 ill.
