GAS STAND Russian patent published in 2023 - IPC G01M3/02 

FIELD: testing technology.

SUBSTANCE: invention can be used to test the tightness of products using vacuum or excess pressure, filling the cavities of products with gas, controlling pressure in the system and testing the system for throughput. A gas stand comprising a two-channel gas supply system, to which gas cylinders are connected through reducers, a stand control panel, a pressure sensor and a vacuum sensor, as well as a gas pumping system consisting of a fore vacuum pump, a piping system, a filter element, an inlet valve air into the forvacuum pump, differs in that the control panel of the gas stand comprises at least seven two-way valves. The gas pumping system is located inside the gas stand. The pressure sensor and the vacuum sensor are located on the instrument panel, comprising a solenoid valve with a timer, inside the gas stand there is a fitting panel, on which the inlet fitting is connected, to which the inlet pipeline is connected, going to the product, and the outlet fitting, to which the outlet pipeline is connected, through which the gas is discharged into the atmosphere.

EFFECT: creation of a gas stand, which allows to check the system for throughput, and increase the maximum operating pressures.
