Abstract

FIELD: pipe line transports; shutting of end sections of pipe lines in conducting tests and repair jobs. SUBSTANCE: shut-off device includes flanges connected by means of axial rod with circular taper sleeve made from stiff material located between them; this sleeve is engageable with flexible sleeve. Ring sleeve is provided with radial cut; parts adjoining this cut are movably connected in overlap; diameter of sleeve is less than inner diameter of pipe line in free state. On opposite side of flexible sleeve, second sleeve with radial cut is provided; their thicknesses are selected within range of definite approximated relationships. EFFECT: enhanced reliability of sealing.

Изобретение относится к трубопроводному транспорту и может быть использовано для перекрытия концевых участков трубопроводов при гидравлических испытаниях и ремонтных работах. Запорное устройство для трубопроводов содержит соединенные осевым стержнем фланцы, между которыми установлена кольцевая коническая муфта из жесткого материала, взаимодействующая с муфтой из эластичного материала. В муфте из жесткого материала выполнен радиальный разрез, и примыкающие к разрезу части соединены подвижно внахлест, так что в свободном состоянии диаметр муфты меньше внутреннего диаметра трубопровода, а в развернутом - больше, причем с противоположенной стороны муфты из эластичного материала предусмотрена вторая вышеохарактеризованная муфта с радиальным разрезом, при этом их толщины выбраны в пределах определенных приближенных соотношениях. Предлагаемое запорное устройство можно использовать в самых неблагоприятных условиях, при этом обеспечивается его хорошая технологичность, достаточная надежность герметизации.The invention relates to pipeline transport and can be used to overlap the end sections of pipelines during hydraulic tests and repair work. The locking device for pipelines contains flanges connected by an axial shaft, between which an annular conical sleeve made of rigid material is installed, interacting with a sleeve made of elastic material. A radial section is made in the coupling of rigid material, and the parts adjacent to the section are lap-jointed, so that in the free state the diameter of the coupling is smaller than the internal diameter of the pipeline, and in the unfolded state it is larger, and on the opposite side of the coupling of elastic material, a second above-described coupling with radial section, while their thicknesses are selected within certain approximate ratios. The proposed locking device can be used in the most adverse conditions, while ensuring its good adaptability, sufficient sealing reliability.
