Abstract

Изобретение относитс  к промьш- ленной и санитарно-техиической .трубопроводной арматуре и может быть применено при стыковке один с другим тонкостенных трубопроводов, выполненных из хрупких материалов Цель изобретени  - повышение эксплуатационной надезкности устройства путем гарантированного исключени  силового перенапр жени  материала стенок соедин емых труб. По достижении вращением винта 5 на выдвижение величины расчетного (допустимого) обжати  труб полумуфта - гайка 1Q, взаимодействующа  с ним и.посто нно упруго поджата  пружиной 11 в осевом направлении с усилием, равным расчетному (допустимому) усилию обжати  труб, размыкаетс  с полумуфтой 9, укрепленной на корпусе устройства. Вс кое дальнейшее вращение винта 5 приводит к его совместному вращению с гайкой 10, исключает его продольное в направлении обжати  труб осевое перемещение и не вызывает приращени  усили  обжати  труб. 6 ил. с The invention relates to industrial and sanitary-technical pipe fittings and can be applied when docking one another with thin-walled pipelines made of brittle materials. The purpose of the invention is to increase the operational reliability of the device by ensuring the exclusion of force overvoltage of the material of the walls of the pipes being joined. When the screw 5 reaches the extension of the calculated (allowable) compression of the pipe the coupling half - nut 1Q, which interacts with it and is permanently elastically preloaded by the spring 11 in the axial direction with a force equal to the calculated (allowable) pressing force of the pipes, opens with the coupling half 9 mounted on the device. Even further rotation of the screw 5 leads to its joint rotation with the nut 10, eliminates its longitudinal axial displacement in the direction of tube reduction, and does not cause an increment of the force of tube reduction. 6 Il. with
