FIELD: testing fluid-pressure systems or apparatus, particularly to determine liquid efflux angles.
SUBSTANCE: device has working liquid source, transparent simulating model of sleeve hydraulic valve, apparatus to obtain fixed images of processes taken place in the simulating model and angle measuring device adapted to measure liquid efflux angles. Simulating model has working and discharge chambers with swinging vanes secured in the chambers by tie members. Each swinging vane has cylindrical holder fixedly connected to medium parts of tie members installed in corresponding chamber and indicative tabs having different lengths arranged in gaps between neighboring tie members. Each indicative tab is installed on cylindrical holders and connected thereto by at least two hinges so that indicative tab may rotate relative indicative holder. Swinging vanes display efflux angles close to angle values, which are integral over throttle window aperture and chamber depth, as well as over chamber width.
EFFECT: increased accuracy of angle determination.
