FIELD: technological processes. ^ SUBSTANCE: method is intended for determination of working medium flows effluent angles in sections of slide hydraulic valves throttle windows. Method consists in putting slide plunger in respect to cartridge of transparent model of slide hydraulic valve in position that maintains set values of fill and drain throttling windows opening, supply of working fluid from source to transparent model of slide hydraulic valve, reception of fixed image of process that takes place in transparent model of slide hydraulic valve, measurement of angles of incline to axis of slide plunger of every of indication petals of flag vanes, which are installed in fill, working and drain chambers at the inlets and outlets of throttling windows in the middle of their sections and in the middle of chambers depths, in which these flag vanes are installed, calculation of average values of incline angles of indication petals of flag vanes in these chambers and calculation of angle values of working fluid flows efflux in fill and drain throttling windows according to given expression. ^ EFFECT: increase of accuracy of determination of effluent angles of working fluid flows in sections of throttling windows of slide hydraulic valves. ^ 4 dwg |
