DEVICE FOR GAS SAMPLING Russian patent published in 2000 - IPC

FIELD: monitoring of content of mechanical hard-dispersive particles in compressed gases. SUBSTANCE: device for gas sampling has probe coming in the form of contraction, sample-tapping tube connected to probe, conical chamber, sample intake branch pipe and sample analyzer. Conicity angle α of contraction is chosen within limits 5 deg<γ>25C. Sample intake branch pipe is manufactured in the form of hollow cylinder with inlet contraction having conicity angle γ chosen within limits 5 deg<γ<40C. Sample intake branch pipe carries handle mounted in its lower part and velocity indicator. Middle part of sample intake branch pipe has outer thread. Bushing with inner thread interacting with outer thread of sample intake branch pipe is installed in central part of lower base of conical chamber. Vertical symmetry axis of conical chamber , sample intake branch pipe, bushing and handle is located on one straight line. Plate having scale of flow velocity marked over its height is positioned vertically on peripheral part of lower base of conical chamber. EFFECT: increased reliability of gas sampling by way of provision of isokinetics of sampling, improved impressiveness of sample. 3 dwg
