Abstract
1. Способ определения содержания свободного газа в жидкости, включающий ввод пробы исследуемой жидкости через открытую запорную арматуру в тарированную по объему рабочую полость с поршнем, установленном в среднем положении рабочей полости, закрывание запорной арматуры, измерение объема и давления пробы, дегазацию пробы и определение содержания свободного газа в пробе, отличающийся тем, что увеличивают объем рабочей полости путем перемещения поршня, вытесняют из рабочей полости выделившийся в результате дегазации пробы газ через газопроницаемую мембрану в газосборную полость с поршнем, установленным в крайнем ближайшем к мембране положении, путем одновременного перемещения поршней рабочей и газосборных полостей, причем объем и давление газа в газосборной полости измеряют после достижения уровня жидкости в рабочей полости газопроницаемой мембраны.2. Устройство для определения содержания свободного газа в жидкости, содержащее тарированную по объему рабочую полость с поршнем, тарированную по объему газосборную полость, соединенные между собой, мано-вакуумметрический измеритель давления газа, подсоединенный трубопроводом к газосборной полости и запорную арматуру, отличающееся тем, что между рабочей полостью и газосборной полостью установлена газопроницаемая мембрана, при этом газосборная полость снабжена дополнительным поршнем, а само устройство приводом перемещения поршней рабочей и газосборной полостей, причем оба поршня установлены с возможностью движения как отдельно, так и совместно, привод перемещения снабжен предохранительным устройством, установленным с возможностью блокировки движения поршня1. A method for determining the free gas content in a liquid, including introducing a sample of the test liquid through an open shutoff valve into a calibrated working cavity with a piston mounted in the middle position of the working cavity, closing the shutoff valve, measuring the volume and pressure of the sample, degassing the sample and determining the content free gas in the sample, characterized in that they increase the volume of the working cavity by moving the piston, displace gas released from the working cavity as a result of degassing the sample through the gas onitsaemuyu membrane into the gas gathering chamber with a piston mounted in an extreme position nearest to the membrane by simultaneously moving pistons and the working gas collecting cavities, and the volume and pressure of the gas in the gas collecting cavity is measured after the liquid level in the working chamber of a gas-permeable membrany.2. A device for determining the free gas content in a liquid, containing a volume-calibrated working cavity with a piston, a volume-calibrated gas collection cavity, interconnected, a mano-vacuum gas pressure meter connected by a pipeline to the gas collection cavity and shutoff valves, characterized in that between the working a gas-permeable membrane is installed in the cavity and the gas-collecting cavity, while the gas-collecting cavity is equipped with an additional piston, and the device itself is driven by a piston displacement actuator and whose gas collecting cavities, wherein the two pistons are mounted for movement both separately and jointly, moving the actuator is provided with a safety device mounted with the possibility of locking the piston
