Abstract

Use: for quickly connecting cryogenic pipelines having low flanges or grooves at the ends of the pipes and a seal between them. The essence of the invention: between the flanges at the ends of the pipes there is a seal. In the case with a U-shaped groove are located around the circumference grips with screws. Screws are placed in holes in the shelves of the case. The body is made of several parts interconnected by hinge inserts. Inserts are installed in the U-shaped groove between the grips. The outer cylindrical surfaces of the inserts and grippers are mated with the inner surface of the housing in the groove and are in contact with it. The inner surfaces of the inserts are in contact with the outer cylindrical surface of the flanges. The screws are fixed in the housing against axial movement. In the shelves are made of central holes of equal diameter. 2 Il.

Description

The invention relates to mechanical engineering and can be used for quick and tight connection of pipelines, including cryogenic ones, having low flanges or grooves at the ends of pipes and a seal between them.

The purpose of the invention is to increase the convenience of operation.

FIG. 1 shows the device, section A-A in FIG. 2; in fig. 2 - view B in figure 1.

The quick-detachable connection contains pipelines 1 and 2 with low flanges, a gasket placed between them, the body 4 in the central hole of which the annular U-shaped groove 5 is bored, and the screws 6 in the holes of the body shelves parallel to the axis of the connection but not moving along it In the U-shaped groove 5 with gaps relative to the cylindrical surfaces of the groove and the flanges on the screws 6, the clamps 7 are fitted, equipped with radial protrusions 8, which are attached to one of the flanges of the pipelines. The housing 4 is cut by radial grooves 9 into several parts 10, which are hingedly connected to each other by inserts 11, also placed in the U-shaped groove 5 of the housing, and axially fixed with fingers 12. The detachable link is fixed by the eyeglass 13, which carries the pull ring 14.

The compound is collected as follows.

In the groove of one of the flanges of the pipelines 1 and 2 install the seal 3 and the flanges are joined together. The housing 4 in the open state and with fully diluted grippers 7 is mounted on the cylindrical surfaces of the flanges, aligning the holes of the part 10 and inserts 11 of the split link and inserting the connecting slip 13 into them. At the same time, the ends of the pipe flanges are between the radial protrusions 8 of the grippers 7 and one of

shelves 4 (from the side of the heads of the screws 6). The central cylindrical opening of the housing, bored in the shelves, encloses the pipelines 1 and 2, keeping them from moving. Next, pre-tighten the joint by screwing the screws 6 into the threaded holes of the grippers 7 in a series-crosswise manner. Then, in the same order, the joint is finally tightened.

Disassembly of the connection is carried out in reverse order. The screws 6 are removed, the radial protrusions 8 of the grips 7 are taken out of the engagement by the soup flange. For the exhaust ring 14, the check 13 is removed from the holes of the split link and the unfolded case 4 is removed from the flanges, which are then removed. Each part 10 along the edges of the cylinder has external and internal bevels that allow the body to be turned almost straight.
