DEVICE FOR TAKING OF GAS SAMPLES FOR TEST TUBE Russian patent published in 1998 - IPC

Abstract RU 2103670 C1

FIELD: examination and analysis of materials. SUBSTANCE: device has measuring chamber made in the form of body with inlet and outlet pipe unions and cover, nipple with circular seals positioned in hole of chamber body, pressed by cover and provided with thrust bead. Device has inlet and outlet channels communicating with outlet pipe union of body and test tube, for example indicator tube, located in measuring chamber and coupled to nipple by means of flexible sealing member. Device is provided with gas flow meter connected behind measuring chamber in direction of gas flow, locking member and locking-control member connected between measuring chamber and gas flow meter. Test tube is coupled to nipple by output end. Body is provided with one or several drain channels communicating the measuring chamber hole with atmosphere and arranged in section between circular seal of nipple and thrust bead. Drain channel flow section or total area of flow sections of several channels exceeds flow area of inlet pipe union of measuring chamber body. EFFECT: more efficient sampling. 3 cl, 3 dwg
