Description

the heating plate 1 is made through the back; pouring. holes .0 using pneumatic

.

This consists of a pneumatic cylinder 8, a lower traverse 9, guide columns 10, an upper traverse 11, and a clamping frame 12. The clamping frame 12 is made quick-release. its size is determined depending on the size and design of the test vessel.

Sealing in places of contact of the ends of the nozzles of the distribution plate 1 with the test vessel 2 is made of gaskets 13, for example, of rubber.

The pneumatic cylinder 9 is controlled by a three-way valve 14 and a shut-off valve 15, the pressure of the compressed air is controlled by a pressure gauge 16.

Fittings 4 and 6 of the distribution plate 1 are connected to a control system consisting of shut-off valves 17, 18, which provide compressed air supply to the even ones; cells 19 of the test vessel 2 through: a group of even pipes 3; from a shut-off valve 20 for connecting the cavities of the even cells 19 with the atmosphere; from the shut-off valve 21 for connecting the cavities of the even cells to the U-shaped manometer 22s from the shut-off valves 23, which supply compressed air to the odd cells 24 through a group of odd nipples 5 of the distribution plate 1; from the stop valve 25 for connecting the cavities of the odd cells 24 with the atmosphere from the stop valve 26 for connecting the cavities of the odd cells 2 to a K-shaped manometer 22; from manometer

27dl control the pressure of compressed air in the control system.

The device works as follows

In accordance with the size and design of the test battery case, a distribution plate 1 is installed on the base plate 7 and a presser frame 12 is mounted to the upper cross-member 11 of the required size. Test vessel 2 is used to determine if there is a leak through the internal partitions

28 is installed on the distribution plate 1 by filling holes (at the ends of the pipes 3 and 5). When the shut-off valve 15 is opened and the three-way valve 14 is switched, compressed air B is supplied to the pneumatic cylinder 8, and the clamping frame 12 creates the necessary pressure 1e to the test vessel 2, providing a tight connection between the pas, distribution plate tubes and the test vessel 2. Stop valves 17 and 18 are opened, and the compressed air of the required pressure through the inlet plug 4 and the group of even nozzles 3 of the distribution plate 1 enters the cavities of the even cells 19 of the receptacle 2 (in this case the stop valves and 2O, 21 23 and 25 are overlapped).

When the shut-off valve 26 is opened, an HG-shaped manometer is connected to the odd-numbered cells 24 of the test vessel 2 through the inlet 6 and a group of odd-numbered 5.

The excess pressure in the cavities of the even cells 19 of the test vessel 2 in the event of a leak in one of the 24 villages 28 (for vessels of the 16 cells) changes the pressure in the cavities of the odd cells 24, which is C-shaped by the 1G-shaped pressure gauge 22.

This checks for the presence of a possible leak through the internal partitions of the test vessel in the direction from even to odd cells. The control of the presence of a leak in the opposite direction, which is necessary according to the test conditions of the vessels, is carried out by creating pressure in the group of odd cells 24 and connecting a group of even cells 19 to 1 / -06 to a different gauge 22. For this, the stop valve 18 is closed and the stop valve opens. valve 2O. After equalizing the overpressure in the even-numbered group with @ ek 19, the shut-off valve 2O is closed, and the shut-off valve 21 opens, providing the connection of the 0-gauge 22 to the group of even cells 19, the shut-off valves 25 and 26 are closed. For overpressure in the group of odd cells 24, a shut-off valve 23 is opened. The presence of a leak in the partitions 28 of the cells is fixed by a 0-shaped manometer 22.
