SU416967A3 - PROTECTIVE-LOCKING DEVICE OF THE AUTO CLAVA COVER - Google Patents

Description

one

The invention relates to devices for protecting the opening of vessel lids in the presence of pressure (vacuum) in them.

Various protective blocking devices for the autoclave covers are known, including a stopper, a pressure relief system from the autoclave to the atmosphere with a shut-off element, and a system for supplying pressure into the cavity of a sealing gasket with a shut-off member.

The aim of the invention is to simplify the design and ensure the reliability of the remote control of the locking bodies in the presence of a vacuum in the autoclave.

This is achieved in that the device is made in the form of three rolls, provided with holes, and has locking strips placed between the rolls, one end of which is provided with a flywheel and the other end of the first roll is connected to the stopper, the second to the locking member of the feeding system (reset a) pressure into the cavity of the gasket, the third — with a closing organ — of the pressure relief system (supply) from the autoclave.

Fig 1 shows a diagram of a protective-blocking device with a part of the autoclave; in fig. 2 shows a device for opening and closing an autoclave cover, side view; in fig. 3 - the same, front view.

The safety locking device is a lever system consisting

from roll 1, roll 2, roll 3, stopper 4, pressure supply (relief) system into the cavity of the sealing gasket 5 with locking member 6, pressure relief (supply) system 7 from

an autoclave with a locking organ 8. Between rollers 1 and 2 there is a stopper bar 9, and between rollers 2 and 3 a stopper bar 10. One end of the rollers I, 2, 3, equipped with flywheels 11, 12, 13. Rollers 3 and 1

have holes a, b, and roll 2 - Vig holes. The stopper 4 of the safety interlocking device is interconnected with the ring 14 connecting the cover 15 and the body 16 of the autoclave. The device works as follows.

Before opening the lid of the autoclave, the system 7 must be connected to the atmosphere. To do this, use the flywheel 13 of the roll 3 to open the locking member 8. At this point, the hole and the roll 3 is against

locking bar 10. When the locking bar moves to the right until refusal, its right end enters the aperture of roll 3 and the left end of the locking bar comes out of the hole in roll 2, after which you can close the locking member 6 of the pressure supply system into the cavity of the sealing gasket 5. When the flywheel 12 rotates, the roller 2 closes the locking member 6 and the compressed air supply to the seal is stopped. In this position

The opening g of the roll 2 is installed opposite the locking bar 9. When the strip 9 moves to the right, its right end enters the hole g, and the left exit from the bore of the roll 1. The roller 1 is free, and when it rotates, the stopper 4 leaves the hole in the flange of the housing 16 ring 14. A double-acting power cylinders 17, rotating the ring to the position at which it comes out of the engagement with the lid, are fastened to the ring 14. The flap is free, the drive 18 is fixed on it, moving the flap with the help of rollers 19 along guide rails 20. Then, using a troso-block system, the vertical guides and the rollers 19 moving along them rises to the top. The lowering and closing of the autoclave cover is carried out in reverse order.

No other sequence of operations will lead to opening (closing), since the rolls are fixed with a locking bar and can only be rotated when they are released, and consequently, the work of the locking organs and the stopper is also blocked.

The proposed design is easy to manufacture and ensures the reliability of remote control of the locking bodies when the autoclave is operating in vacuum or under pressure.

Subject invention

The protective-blocking device of the autoclave cover, comprising a stopper, a pressure relief system (supply) from the autoclave to the atmosphere with a shut-off member, and a pressure supply system into the cavity of the gasket, provided with a shut-off member, characterized in that, in order to simplify the design and ensure the reliability of remote Controls: by 3 supporting bodies, if there is a vacuum in the autoclave, it is made in the form of three rolls, provided with holes, and has locking plates placed between the rolls, one end of which is equipped with a flywheel And the other end of the first roller is coupled with the stopper, the second - with a locking organ system supply pressure in the cavity of the sealing gasket, the third - with a locking organ system reset (discharge) pressure from the autoclave.
