FIELD: test equipment.
SUBSTANCE: invention relates to test equipment and can be used for adjustment, inspection and testing of automatic circuit breakers of emergency shutdown of main gas pipeline valve. Device consists of a container for compressed gas with a pressure gauge and a line connected to it for connection of an automatic device of emergency closing of a valve and a line for gas pressure relief to atmosphere. In the line for gas pressure relief to atmosphere, there are sequentially installed in the direction from the compressed gas container: shut-off valves, a pressure regulator after itself, a pressure gauge (pressure sensor), and a throttle.
EFFECT: providing a process of testing and adjusting automatic devices for emergency closing of a valve, increasing accuracy of testing and adjusting due to implementation of pressure drop according to a linear law and control of the pressure drop process.
