Способ определения утечек газа в двухсторонних регуляторах расхода с регулируемыми минимальными расходными отверстиями, заключающийся в поочередных продувках газовых трактов каждого из выходных патрубков при одном перекрытом регулирующем элементе, а другом полностью открытом, и замере давлений в проточной части каждого из трактов, отличающийся тем, что газовый тракт, перекрытый регулирующим элементом, дополнительно герметизируют заглушкой на выходе и проводят дополнительную продувку и по полученным замерам определяют величину утечек каждого из выходных патрубков по формуле:A method for determining gas leaks in two-way flow controllers with adjustable minimum flow openings, which consists in sequentially purging the gas paths of each of the outlet pipes with one closed control element and the other completely open, and measuring the pressure in the flow part of each of the paths, characterized in that the gas the path blocked by the regulating element is additionally sealed with a plug at the outlet and additional purging is carried out and the leakage value is determined by the measurements obtained ek of each of the outlet connections of the formula:

Figure 00000001
 где μFΣ - суммарная эффективная площадь выходных патрубков, расходное отверстие одного из которых полностью открыто, а расходное отверстие другого перекрыто регулирующим элементом;where μF Σ is the total effective area of the outlet pipes, the flow opening of one of which is fully open, and the flow opening of the other is blocked by the control element; μF - эффективная площадь выходного патрубка, расходное отверстие которого полностью открыто, при установленной в другой выходной патрубок герметизирующей заглушки.μF is the effective area of the outlet pipe, the supply opening of which is fully open, when a sealing plug is installed in the other outlet pipe.
