Description

i

This invention relates to mechanical engineering, in particular to hermetic closures for pressure vessels.

Sealed closures for pressure vessels and vessels are known.

The purpose of the invention is to provide a sealing cap on the vessel.

To do this, flanges are made on the lid and on the vessel, which are directed in opposite directions, on which there is an enclosing split elastic ring that has annular grooves open into the interior, in which elastic seals are inserted, which interact with the flanges when the ring is tightened and the pressure is applied into the vessel.

In addition, the device for tightening the ring is made in the form of two radially directed and parallel to the radius of the rods, between which an elastically expanding and tightening device is installed, and in the gate along the periphery opposite the ring there are guide rollers, and the ring in the middle part has recesses videos.

condition; in fig. 3 - the same, in the closed state.

Hermetic shutter consists of a split elastic ring 1 with annular grooves

2, in which elastic seals 3 are placed, covers 4, vessel 5, flanging 6, rods 7, expanding and tightening devices 8, rollers 9, and recess 10. When closing, cover 4 enters SwanMP by flanging under ring 1; under the action of the expanding fastening device 8, which compress the rods 7, connected to the ring 1, the diameter of the split ring decreases, and its ends converge. When pressure is applied

Into the flange vessel 5, the vessel lids are pressed tightly against the elastic seals 3 placed in the annular grooves 2. The guide rollers under which the ring 1 in the middle part has depressions 10 orient the ring 1 relative to the body. the pressure of the cover to the seals m.

Claims (3)

1. A sealed closure for pressure vessels, characterized in that, in order to ensure the sealing of the lid on the vessel, on them. flanges are made that are directed to the anti-nolol side, on which there is an enclosed split elastic ring, having annular grooves open into the inside, in which elastic seals are placed, interacting with flanging when the ring is pressed and the pressure is applied to the vessel. 2. The closure according to claim 1, characterized in that the device for tightening the ring is made in the form of two radially directed and parallel to the radius of the rods, between which are installed an elastically arching and tightening device. 3. The shutter on the PP. I and 2, characterized in that there are guide rollers located on the periphery opposite the ring, and the ring in the middle part has recesses for these rollers.
