Abstract

This invention relates to hermetic enclosing structures and can be used in installations for temperature test conditions. The aim of the invention is to increase operational safety and simplify the design. The device for sealing the chamber opening includes an inclined frame 13, a door leaf 3, a guide 8, microprotectors 4, anchors 1e in the lower part of the blade, and an actuator 7. The guide 8 is made with a longitudinal groove for the guide roller II and is hinged with one the end on the frame 13 through the cantilever beam, and the other is connected with the drive 7. The lower edge of the blade 3 is woven, and the bevel angle of the edge of the blade is equal to the angle of inclination of the frame 13 4.

This invention relates to hermetic; enclosing structures and can be used in installations for temperature tests.

The aim of the invention is to enhance the safety of operation and control of the structure,

Figure 1 presents a General view of the device; Fig. 2 is a view A of fig. and Fig. 3 is a section BB in Fig. 1 (opening; not sealed); figure 4 - we close the camera sealed) of the connections bb in figure 1,

 The device dp sealing the projection 1 of the chamber 2, the floor of which is flush with the floor of the workshop, contains a canvas of the gate 3 with brackets 4 on which the rollers 5 mounted in the groove 6 of the floor of the workshop are fixed. At the top of the chamber, 2, a drive 7 is installed and a guide | pushed 8 with a longitudinal groove 9, and one end of the guide 8 of the hinge Hoi is fixed to the chamber 2 via a cantilever beam, and the other is connected to the drive 7, On the upper edge 10 of gate 3, a guide roller П, INLINE 10 is installed in groove 9 of guide 8. Lower | k | The gate 12 of the gate 3 is inclined to the horizontal plane at an angle peniaiM of the angle of the framing - 13 openings 1 of the chamber 2. Thermal insulation seals are spaced around the frame of the opening 13 and the lower edge 12 of the gate 3

ii and 15.

; The device for sealing the opening of the camera works in the following way. After loading through the opening 1 of the camera 2 manually or driven (not shown), gate 3 begins to overlap with passage 1 of chamber 2. At the same time, rollers 5 roll along groove 6 of the workshop floor, and roller 11 moves inside the groove 9 directions 8, holding gate 3 in a vertical position of the scientific research institute. Since the rollers 5 are mounted on the HieKOTOpoM distance from the outer edge of gate 3, and the edge 12 of gate 3 and frame 13 of opening 1 of chamber 2 are sloped, then between the heat insulating seal 14 and gate 3, as well as between the heat 15 In the hollow workshop there are gaps when the gate 3 is in a vertical position.

After the overlap of the oblique border 13 of the chamber 1 of camera 2 is completely blocked, gate 3 is stopped and turned on; drive 7 that turns on

equal 8. Since the roller / 11, mounted on the upper edge 10 of the gate 3, enters the groove 9 of the guide 8, together with the turn of the guide 8 will begin to deviate towards the opening

1 chambers 2 gate 3, which fit tightly on the seal 14 of the inclined framing 13. At the same time, the bottom of the opening 1 of the chamber 2 is sealed with a seal 15 installed on the lower edge 12 of the gate. 3. The opening 1 of the chamber 2 is reliably sealed, since the seals 14 and 15, in addition to the drive force 7, are additionally affected by the weight force of the gate 3. This ensures that the axis of rotation of the gate 3 is displaced from its center of gravity, because the gate 3 is deflected on rollers 5, which mounted on brackets 4.

Depressurization of the opening I camera

2 is produced in reverse order.

Gate 3 can be made of two flaps, then the drive 7 is mounted on chamber 2 above the middle of opening 1, two guides 8 J are installed, and an additional seal is inserted between the flaps.

- The use of this device ensures reliable sealing of the camera opening along the entire perimeter by tilting the gate, i.e. laying them on the insulating seal.
