FIELD: test technology.
SUBSTANCE: invention relates to stands for control and testing of respiratory and safety valves, in particular, valves of reservoirs, and is intended for check of operability for actuation and determination of maximum efficiency of reinforcement. Test bench for testing respiratory and safety valves of reservoirs comprises a compressor-vacuum device, pressure and vacuum sensors, control cabinet, inlet and outlet branch pipes connected to air flow rate measuring unit containing pipeline with detachable diaphragm; at that, two differentiated pressure sensors installed at equal distance before and after detachable diaphragm and resistance sensor are located in pipeline cavity.
EFFECT: high efficiency of operation of the stand due to the possibility of the test bench to test the valves of different diameters while ensuring high accuracy and reliability of test results with possibility of visualizing the tests.
