Description

The invention relates to a sealing technique and can be used for sealing flange connectors in the joint of parts.

The purpose of the invention is to increase the reliability and service life by making reinforcement rigid structure.

FIG. 1 shows a seal, a general view; in fig. 2 - rebar rings; in fig. 3 - seals during joint assembly; in fig. 4 - the same in work.

The seal is an o-ring with a rectangular cross-section, which is located by the joined parts 2 and 3.

At parts x 2 and 3 there are bores 4 and 5 in which the sealing ring 1 is placed. The sealing ring 1 is completely made of elastic material 6 (rubber, fluoroplastic, etc.) and its internal cavity is reinforced with m & talli split rings 7 - 10. The rings (Fig. 2) cut the radial of HbHviH with the slots 11 into segments 12. The rings are made with a triangular cross section with a melting angle of 13 at the apex of the triangle and are facing each other and contacting (in the assembled ring, (1) needle 1) round curves with each other.

When assembling the seal (Fig. 3), parts 2 and 3 are stacked until they touch in junction 14. Seal ring 1 is slightly larger in axial dimensions than bores 4 and 5

squeezed the bottom of the bore and it acts on both sides of the force 15 and 16, which through the elastic base 6 are transmitted to the rings 7 and 8. The rings 7 and 8 are pressed against the rounds I3 of the rings 9 and 10 and pushed them apart and pressed against the walls of the bores 4 and 5 at the junction 14, sealing the joint.

During operation, the sealing ring 1, by the elastic forces of the elastic base 6, forces against compression during assembly, presses to all the walls of the bores 4 and 5 and the joint 14, seals

connector.

In cases of increased pressure, for example, from the side of side 1 7 of joint 14 and its penetration into bores 4 and 5, elastic base 6 is somewhat deformed and stripes appear between the walls of bores 4 and 5 and base 6 .18 sec. Increased pressure. On this side, ring 10 acts additionally increased force 19, which moves ring 1 O towards ring 9. Moving, ring 10 presses rounding rounds 13 rings 7-9 and moves and: towards the bore walls 4 and 5. At the same time

the degree of pressing of the ring on these places increases and the hermetic sealing improves. the walls of the bores 4 and 5 and the joint 14 in the place 2.0. Sealing properties of the seal are improved.

The same (in the opposite direction) occurs if an overpressure occurs from the side 17 of the joint 14.
