Abstract

The invention relates to mechanical engineering and allows to expand the functionality by providing the output of the gate to a vertical position and fulfilling the function of the protective partition when the liquid in the tank is heated to high temperatures. Guiding supports consisting of two parts 1 and 2 are attached to two opposite and parallel outer walls of the container 3. Part 1 is fixed rigidly, part 2 can be rotated on an axis through an angle of 90 in one direction relative to the stop by means of a hinge with a return spring 7 On the lid 9 there are two brackets fixed, each of which has a pair of rollers 8 and 10 rolling over the upper and lower surfaces. The knobs of the key 9 roll out in parts 1 and 2 of the guides on the rollers 8 and 10 up to the stop of the roller in the limiter 24 of movement. After rolling out Krishka 9, not supported by the handles, under the action of its own weight, it rotates into a vertical position with part 2 to "(

The invention relates to mechanical engineering, in particular to closures for containers, and can be used when testing products for tightness at high temperatures.

The aim of the invention is to extend the functionality by allowing the sliding shutter of the container to be moved from a horizontal position to a vertical one, in which the shutter fulfills the function of the protective partition, ensuring the safety of the personnel during the testing of products.

FIG. 1 showing sliding shutter general view; in fig. 2 is a view A of FIG. FIG. 3 shows the node I in FIG. one; in fig. 4 shows a section BB in FIG. I.

The sliding gate of the container contains two guides, each of which is made in the form of two located on the same straight parts 1 and 2. Parts

1 and 2 of each rail are fixed on parallel side walls of tank 3, part 1 is fixed to tank 3 rigidly, and part 2 is rotatable on axis 4 through an angle of 90 in one direction relative to stop 5 by means of a hinge 6 with a return spring 7,

The hinge 6 is fixed on the container 3 and on the end of the part 2 of the guide. The first rollers 8 are fastened on the roof 9 with an offset relative to the straight line passing through the center of gravity of the cover 9 parallel to the axis of the hinge 6, and the second rollers 10 of each pair are in contact with the surfaces I1 of parts 1 and

2 guides opposite to surfaces 12 in contact with the first rollers 8.

A cover 9 with a seal 13 and two pairs of rollers 8 and 10 is mounted on parts 1 and 2 of the guides so that the first rollers 8 of each pair contact the surfaces of 12 parts

The I and 2 guides are facing toward the roof 9, parallel to it and having recesses 14. In the tank 3, a bath 15 is installed filled with liquid and closed with a cover 9. Between the tank 3 and the bath 15 there is a space in which the heat insulating material 16 is placed.

In the walls of the bath 15, windows 17 are closed, covered with glasses 18, through which the internal volume of bath I5 is illuminated with electric lighting devices 19. Through heaters 20 inside the bath I5, electric heating elements 21 are inserted under the shelving 22 on which test object 23 is installed.

The movable part 2 of the guide is connected with the spring 7, pressing one end thereof towards the stop 5, and the other end thereof is designed as a movement limiter 24. Two brackets 25 and 26 are fixed on the roof 9, each of which has a pair of rollers 8 and 10 mounted on axes 27 and 28. The position of the axes 27 and 28 is chosen so that rollers 8 and 10 roll over the top 12 and bottom

I1 surfaces of parts 1 and 2 of the guides. Krsch 9 are welded handles 29.

The sliding shutter works as follows.

In the closed position of the cover 9, the rollers 8 are located on a lowered area — a recess 14 of the fixed part 1 of the guide. The cover 9 lies on the sides of the bath 15, resting on them through the seal 13, sealing the joint between the bath 15 and the roof 9. Through the electric heaters 21, the liquid in the bath 15 is heated

 up to operating temperature, for example up to 90 ° C for water.

By the handles 29, the cover 9 is moved along the guides 1. At the initial moment of moving the cover 9, the rollers 8 come out of the lowered section - the recess 14 of the part 1 of the guide, lifting the key 9 above the sides of the bath 15, after which the key 9 by the handles 29 rolls out on the rollers 8 and 10 until the upper roller 8 stops against the movement limiter 24 on the guide part 2,

In this case, due to the fact that the axes of the rollers 8 and 10 are spaced apart in the direction of movement, parts 1 and 2 of the guide do not allow the crink 9 to deviate from the horizontal position, at which it does not contact the sides of the bath 15.

After rolling out the flap 9, it is not supported by the handles 29; under the action of its own mass, it rotates into a vertical position along with parts of 2 guides that rotate around axis 4. The rotational moment caused by the mass of the crutch 9 is balanced to a greater degree by the torque generated by the force of the spring 7. This ensures a smooth rotation of the cover 9 when lowering and lowering efforts to bring it to a horizontal position during shrink-; Nii. In the open position, the front part of the roof 9 is lowered and positioned along the outer surface of the wall of the container 3, and the rear part is raised above the sides of the bath 15, forming a barrier preventing the personnel from approaching the surface heated to a high liquid temperature.

Claims (1)

The test object 23 is placed in the bath 15, in closed cavities of which the gas is under atmospheric pressure, it is heated, the gas expands, its pressure increases, which visually allows to detect leaks on the evolved gas bubbles. After the end of the test, the object is removed from the bath 15, which can then be closed with a crack 9, for which the lid 9 is placed in a horizontal position and pulled over the bath 15. Claims A sliding gate of a container containing guides fixed on parallel side walls of the tank and a seal with a seal and two pairs of rollers mounted on the guides so that the first rollers of each pair contact with the surfaces of the guides parallel to the cover and having dimpling, characterized in that, in order to expand the functionality, each of the guides is made in the form of two located on one straight part, one of which is fixed to the body rigidly, and the other with Turning 90 by means of a hinge with a return spring fixed on the container and on the end of the guide, the rollers are fixed on the cover displaced relative to the straight line passing through the center of gravity of the cover parallel to the axis of the hinge, and the second rollers of each pair contact the surfaces opposite surfaces in contact with the first rollers. 20 25 thirty 35 40 / .eight "12 7 L Fi, s Phia.2 L 28 6-5
