Abstract

The invention relates to a testing technique and can be used in the charging of products by the working bodies and their emptying with the transfer of the working substance to the source. The purpose of the invention is the expansion of technological capabilities. The installation contains a multiplier 1 with cavities 5 and 6. In cavity 5 there are three check valves 2.3 and 4, valves 2 and 4 are located downstream to multiplier 1, and valve 3 is downstream from multiplier 1. Multiplier 1 through valve 2 and the stop valve 10 is connected to the source 11 of the working fluid, and through the valve 3 and the three-way valve 13 by pipe 12 to the product 18 and through the valve 4 and the stop valve 21 by pipe 20 to the product 18. The three-way valve 13 is connected by pipe 19 to the source 11 . Opening the valve 10 and moving the three-way valve 13 to the position The cavity 5 and the product with the valve 21 closed, the product 18 is filled with the working fluid, connecting the multiplier 1 to the source of the propellant gas. The valve 21 is opened and the three-way valve 13 is transferred to the position of communication of the fittings 14 and 15 by connecting the multiplier 1 and pumping the working fluid to the source 11. 1 sludge.

The plug 1 through valve 2 and the shut-off valve 10 is connected to the source 11 of the working fluid, and through valve 3 and the three-way valve 13 - by the pipeline 12 - with the product 18 and through the valve 4 and the main valve 21 by the pipeline 20 - also with the product 18. Three-way The valve 13 is connected by a pipe 19 with the source 11. Open the crane 10 and transfer the three-way valve 13 according to the Invention with respect to testing equipment, namely, installations for a gas generator for irx testing and operation.

The circuit of the invention is the expansion of technical capabilities by providing the possibility of a reverse transfer of the working fluid to the source without re-installing the product.

The drawing shows the schematic diagram of the proposed gas charge facility.

The IZOsdelch gas installation contains a pressure source in the form

multiplier 1 with three check valves 2, 3 and 4, cavity 5 and cavity 6, with which it is connected via an electropneumatic valve 7 with a source (the drawing does not show propellant gas. Perviz the check valve 2 is installed along the working fluid flow to the multiplier I, the second check valve 3 is downstream of multiplier 1, and an additional check valve /; as well as the first one - downstream to multiplier 1. Cavity 5 of multiplier 1 through first B1 reverse Hbtfi valve 2 by first pipeline 8 with shut-off valve 9 and additional stop valve Connect by crane 10 A working medium source 11 is connected to the cavity 5 of the multi-puller 1 through the second check valve 3 a second pipe 12 is connected, in which a three-way shut-off valve 13 COOTBET is installed with three fittings 14, 15 and 1. The second pipe 12 is equipped with a fitting 17 for connecting the 18. A three-way shut-off valve 13 with its fitting 14 and pipe 19 is connected with the first pipeline 8 between the shut-off valve 9 and the additional shut-off valve 10. The cavity 5 of the multiplier 1 through the additional

The message of the cavity 5 and the product when the valve 21 is closed, refills the product 18 with the working fluid, connecting the multiplier 1 to the source of the propellant gas. The valve 21 is opened and the three-way valve 13 is turned into the position of communication of the fittings 14 and 15 by using the connection 1 and the multiplier 1 to pump the working fluid to the source 11. 1 Il.

the check valve 4 is connected by pipeline 20 with a shut-off valve 21 to the second pipe 12. The installation is equipped with means for controlling the pressure of the working fluid (not shown).

The gazozar dki installation works in a skinny manner.

When the product is charged with the working fluid, a shut-off valve 9 is opened at the source 11 of the working fluid, an additional shut-off valve 10, a three-way valve 13 are placed in position to connect fittings 15 and 16, the shut-off valve 21 is closed. Using an electropneumatic valve 7, they turn on the multiplier 1 and filling the working fluid of the product 18, controlling the pressure of the working fluid.

If it is necessary to return part or all of the working fluid to the source, then close the additional shut-off valve 10, open the shut-off valve 21, and the three-way shut-off valve 13 is transferred to the position of communication of the fittings 14 and 15 and pump the working fluid to the source 11 by means of the display-type 1

Thus, the proposed gas jet set allows you to fill the product with the working fluid and transfer the working fluid from the product to the source without moving the product into the installation, which greatly expands the technological capabilities of the installation.
