FIELD: instrument engineering. ^ SUBSTANCE: pressure nozzle comprises tip with inner passage and outer pipe rigidly connected with the tip. The ring slot is made at a distance of 3d (where d is the outer diameter of the pipe) from the front end of the tip and is connected with the inner passage of the outer pipe. Additional radial through openings are arranged symmetrically in the plane perpendicular to the longitudinal axis of the pressure nozzle. The openings at the second section are turned with respect to these positioned at the upstream section at an angle of 45°. The total area of the additional openings is equal to area of the slot. ^ EFFECT: enhanced accuracy of measurements. ^ 3 dwg |
