Abstract

The invention relates to a sealing technique. It makes it possible to increase the reliability of sealing and usability. The plug contains an extension bolt 1, a sealing element 3 mounted on it with blind axial holes 16 on both sides in which the pins are placed, and 17 of the upper and lower washers (W) 4 and 2. On the bolt 1 by means of a splined joint between W 4 and a nut 5 mounted figure ring (FC) 11 with cutouts on the outer surface. On W 4, gripping handles 18 and a FK 11 rotation stop are included, which is included in one of the notches. Swivel stops in the inner collar of 6 vessels are made in the form of 2 cams (K) installed under W with toothed sectors. The rotational drive of the stops is embodied in the form of a gear 10 fastened to the bolt 1, which is engaged with the sectors. With W 2, there is a rigidly fixed abutment plate 15, located on the other side of it K. When the FC 11 is rotated all the way into the stopper, the bolt 1 rotates relative to W 4, and element 3 and W 2 are fixed. As a result, the bolt 1 is rotated relative to W 2, and the wheel 10 spreads K, leading them beyond the dimensions of the container opening. The nut 5 is then wrapped and K rests on the collar 6. Element 3 is compressed between Ø 2 and 4, sealing the vessel. The pressure of the medium in the vessel K holds the cap, and plate 15 does not allow K to turn out. 2 hp ff, 4 ill. With S (L oo ke 1C

Description

The invention relates to a sealing technique and can be used to seal high-pressure vessels when tested for tightness.
The purpose of the invention is to improve the reliability of sealing and ease of operation.
Figure 1 presents the stub, a General view; figure 2 - section aa in figure 1; Fig. 3 is a section B-B in Fig. 1 (cams in a divorced state); 4 is the same, cams in a reduced state.
The cap for pressure vessels contains a clamping bolt 1, successively installed on it a lower washer 2, a sealing element 3, an upper washer 4 and a nut 5, pivoting stops in a vessel 6 of a vessel (not shown) in the form of cams 7 with toothed sectors 8, mounted under the bottom washer 2 and associated axles 9, driving the cams 7 in the form of a gear 10 fixed to the strut bolt 1 engaging with the gear sectors 8 cams 7, figure ring 11 with notches 12, installed on a stand
the filament element 3 and the lower washer 2 due to the pins 17 entering the holes 16 of the sealing element 3 remain fixed relative to the upper washer 4. As a result, the tightening bolt
1 is turned relative to the lower washer 2, and the gear wheel 10, interacting with the gear sectors 8 of the cams 7, spreads the last
10 (fig.Z). In this case, the cams 7 extend beyond the dimensions of the opening of the container. Now holding the figure ring 11 by the handles 19, the nut 5 is wrapped. In this case, the cams 7 rest against the inner shoulder of the vessel 6 and the sealing element 3 is pressed between the washers
2 and 4, hermegziru vessel. The pressure of the medium in the vessel is eaten by the cams 7, which, resting on the shoulder 6 of the vessel,
20 retain the plug, and the anvil plate 15 prevents the cams 7 from being raised, providing the necessary stiffness and reliability of retaining the caps.
25 The plug is dismantled in reverse order.
The effectiveness of the plug is to improve the reliability of the seal and the convenience of its operation over
the bolt 1 between the upper washer 4 and the gay-30 by means of ensuring the drive of rotation 5, by means of a spline connection of the stops with a fixed bolt in the absence of
in the form of a groove 13 of the rod 1, and a tooth 14 which enters it 14 of the ring 11, and an anvil plate 15 rigidly connected with the lower washer 2 and located on the other side of the cams 7. The sealing element 3 on both sides has non-through, axial the holes 16, both washers 2 and 4 are made with studs 17 entering the holes 16, the upper washer 4 has gripping handles 18, and the nut 5 has handles 19. The upper washer 4 is also provided with a stop 20 for rotating the ring 11 which is part of one of his descriptions 12.
The plug works as follows.
The plug is installed in the hole
(not shown) capacity Cams 7 at 50 nut, pivoting stops in the inside are reduced (figure 4). Holding the upper edge of the vessel and the rotation drive
different with
4 washer 4 by the handles 18, turn the figure ring 11 clockwise until it stops at the stop 20 of its rotation. Since the prong 14 of the ring I enters the groove 13 of the clamping bolt 1, the latter rotates together with the ring 11 relative to the upper washer 4, while seals, which, in order to increase the reliability of the sealing and ease of operation, 55 under the lower washer and its associated cams with the toothed sectors, and the drive of their rotation in the form of a gear mounted on the clamping bolt

the filament element 3 and the lower washer 2 due to the pins 17 entering the holes 16 of the sealing element 3 remain fixed relative to the upper washer 4. As a result, the tightening bolt
1 is turned relative to the lower washer 2, and the gear wheel 10, interacting with the gear sectors 8 of the cams 7, spreads the last
(fig.Z). In this case, the cams 7 extend beyond the dimensions of the opening of the container. Now holding the figure ring 11 by the handles 19, the nut 5 is wrapped. In this case, the cams 7 abut against the inside shoulder of the vessel 6, and the sealing element 3 is pressed between the washers
2 and 4, hermegziru vessel. The pressure of the medium in the vessel is eaten by the cams 7, which, resting on the shoulder 6 of the vessel,
hold the plug, and the stop plate 15 prevents the cams 7 from being raised, providing the necessary rigidity and reliability of holding the caps.
The plug is dismantled in reverse order.
The effectiveness of the plug is to improve the reliability of the seal and the convenience of its operation over
additional through holes in the sealing element. A washer connected with a spitz-nut with a clamping bolt provides the convenience of its rotation relative to the washer connected to each other through a sealing element, and a stop plate provides the necessary
40 cam stiffness and thus secure fastening of the cap.
