Description

one

The invention relates to mechanical engineering, in particular to vacuum chambers with controlled atmosphere inside the chamber.

The purpose of the invention is to improve the reliability of the sealing chamber.

The drawing shows a vacuum chamber (fragment).

The vacuum chamber has a flange 1 with a central hole and a mounting nest. In KOTop.oNf p: th: a glove 2 and a ring 3 are laid To fasten it, pressed by springs 4 to the washer 5, fitted with screws 6 evenly spaced around the circle, contacting the ring 3. Between flange and ring

5 To replace the glove 2, it is necessary to unscrew the screw 6; under the action of the springs 4, the ring 3 is pressed to the washer 5 and releases the glove. The glove is taken out together with the elastic element 7 10 and separated. The installation of the glove is carried out in reverse order. During evacuation, air is simultaneously pumped out of the cavity of the chamber and out of the cavity of the glove 2 through the channel 12 of the clamp 5, connected to the cavity of the chamber (the connection is not shown). Sealing the cavity. Gloves 2 are provided with seals 10 and 11. After the chamber has been created, the required 3 are formed, which changes in height.

The cavity in which the elastic degree of vacuum is installed, the channel 12 overlaps the element 7 (rubber ring), is wrapped, and the cavity of the chamber is filled with the railing edge of glove 2. To the washer 5 with sub-gas, such as argon. The central screw of the 8 part 9 is assembled by the central screw of the 8 part 9 of the outer cover, which forms with this washer and is withdrawn from the mating with the washer 5 and ne, and closed with a glove to the cavity.
