Изобретение относитс к устройствам дл отбора проб в газообразном состо нии , например воздуха, и может быть использовано в здравоохранении при текущем санитарном надзоре за состо нием воздушней среды, при гигиенической оценке загр зненности воздуха вредными химическими веществами.The invention relates to devices for sampling in a gaseous state, such as air, and can be used in health care in the current sanitary supervision of the state of the air environment, in the hygienic assessment of air pollution by harmful chemicals.
Известно устройство дл отбора проб воздуха, содержащее поглотительный прибор с поглотителем, расходомер и побудитель расхода воздуха с нагнетающим и отсасывающим щтуцерами и приводом, соединенные между собой так, что воздух проходит последовательно через расходомер , поглотитель и побудитель расходаA device for sampling air is known, comprising an absorption device with an absorber, a flow meter and an air flow stimulator with an inlet and suction fittings and a drive interconnected so that air passes successively through the flow meter, absorber and flow discharger.
ИИзвестно также устройство дл отбора проб среды, содержащее побудитель расхода , поглотительный прибор, расходомер, вход которого соединен с нагнетающим щтуцером побудител расхода, а выход св зан с поглотительным прибором Г21.A device for sampling the medium is also known, containing a flow booster, an absorption device, a flow meter, the inlet of which is connected to the injection pump of the flow driver, and the output is connected to the absorption device G21.
Недостатком известного устройства вл етс то, что при прохождении среды через поглотитель он мен ет свое сопротивлерше и при его изменении измен етс расход воздуха через расходомер, в силу чего погрешность в определении расхода воздуха возрастет.A disadvantage of the known device is that when the medium passes through the absorber, it changes its resistance and when it changes, the air flow through the flow meter changes, and therefore the error in determining the air flow will increase.
С целью устранени указанного недостатка , на выходе расходомера установлен жиклер.In order to eliminate this drawback, a jet is installed at the outlet of the flow meter.
