Abstract

This invention relates to joints of flexible sleeves with fittings. The purpose of the invention is to increase durability and tightness. A device comprising a nipple 1, a sleeve 7, a split sleeve made of separate sectors with internal protrusions and an outer conical surface, as well as two spacer sleeves 4 and 5, the inner conical surfaces of which interact with the outer conical surfaces of the split sleeve, provided with a clip, a fastener split springs and spring in the radial direction, and the spacers are connected to the coupling thread of the opposite direction, and these sleeves have through-slotted grooves through which ohod m pitch guide 6 fixed to the flange 14 of the nipple. 1 hp f-ly, 5 ill.

Parts of the nipple 1 through the through-slotted grooves of the flange 14 insert the petals 15 of the guide 6 until it stops by the shoulder 16 into the flange 14 of the nipple 1.

The clutch 7, assembled with spacers 4 and 5, of the clamping body 3 is guided to the cylindrical guide 6 and through the through sector grooves about the spacer sleeves 4 and 5 fits on the petals 15 of the guide 6 until it stops at the end of the clutch 7 in the flange 14 of the nipple 1 o Compression sleeve 2 is carried out by a clamping body 3, which interacts with external conical surfaces with internal conical surfaces of the ram bushing 4 and. 5o. When the coupling 7 rotates, connected with 5 n 4 sleeves with threads, in the opposite direction, the spacers 4 and 5 slides along pestkam 15 of the cylindrical guide. 65 approach and, due to the inner conical surfaces of the outer conical surfaces of the clamping body 3, cause the sectors 12 of the clamping body 3 to move radially on the board and compress the sleeve 2 until it fully closes, creating a uniform contact size. stress on the circumference between the inner surface of the sleeve and the sub-surface of the n-1ppel. The diameters of the inner surface of the clamping housing 3 are calculated in such a way that when the clamping housing 3 is compressed until the sectors 12 are fully closed, a reliable sealing of the junction 12 is ensured.

When reaching the closure of the sectors 12 of the lower body 3, the cap nut 8, which engages with the nipple 1 and the cylindrical guide 6, twists the end of the coupling 7 in order to increase the resistance of the detachable connection to the axial tearing out of the sleeve 2 and prevent spontaneous disassembly of the coupling during operation.

Claims (2)

Invention Formula 1 o Detachable connection of an elastic sleeve with connecting fittings; containing a nipple inserted into the end of the sleeve, a sleeve, split vtl lAU made from separate sectors with internal projections and external conical surface. 51 as well as two spacers, the inner conical surfaces of which interact with the outer conic surfaces of the split sleeve, characterized in that, in order to increase the durability and tightness of the joint, the sectors of the split sleeve are fastened in the radial direction of the sleeve, and the spacers are connected to the coupling by means of rez 12 13 202.92 and, on these sleeves, the threads are oppositely directed and in the sleeves there are made through sector grooves through which the guides fixed with the nipple are passed. 2.
