Description
Изобретение относитс к области тарирозки расходомеров.This invention relates to the field of charge metering.
Известные стенды аналогичного назначени расходуют большое количество энергии, имеют сложную систему охлаждени .Known stands of similar purpose consume a large amount of energy, have a complex cooling system.
В описываемом стенде эти недостатки устранены благодар выполнению его в виде двухконтурного трубопровода с трем ветв ми , в одной из которых установлены воздуходувка и теплообменный аппарат, в другой - образцовый и повер емый расходомеры и исполнительный орган, в третьей - исполнительный орган, перекрывающий ветвь в момент открыти исполнительного органа во второй ветви.In the described stand, these deficiencies are eliminated due to its implementation in the form of a double-circuit pipeline with three branches, in one of which a blower and a heat exchanger are installed, in the other - exemplary and adjustable flowmeters and the executive body, in the third - the executive body that closes the branch open the executive branch in the second branch.
На чертеже представлена схема предлагаемого стенда.The drawing shows the scheme of the proposed stand.
Стенд содержит замкнутый кольцевой трубопровод 1 с воздуходувкой 2, расположенной внутри него, ко.мпрессор 3, наход щийс вне трубопровода. В основной ветви кольцевого трубопровода расположены исполнительный орган (задвижка) 4, образцовый 5 п повер емый 6 расходомеры, устройства дл измерени и поддержани необходимых параметров газа (манометр 7, термометр 8, регул торы давлени 9 и 10, ресивер //).The bench contains a closed annular pipeline 1 with a blower 2 located inside it, a co-compressor 3 located outside the pipeline. In the main branch of the ring pipeline, there is an actuator (gate valve) 4, exemplary 5 and 6 adjustable flowmeters, devices for measuring and maintaining the required gas parameters (pressure gauge 7, thermometer 8, pressure regulators 9 and 10, receiver //).
Замкнутый трубопровод имеет ветвь с исполнительным органом (вентиль или кран) 12, теплообменник 13 и кран 14.A closed pipeline has a branch with an executive body (valve or tap) 12, a heat exchanger 13 and a tap 14.
При помощи компрессора через ресивер и регул тор давлени в трубопроводе создаетс и поддерживаетс нужное статическое давление . Воздуходувкой регулируетс расход газа,With the help of a compressor, the required static pressure is created and maintained through the receiver and the pressure regulator in the pipeline. The blower regulates the gas flow,
который при по.мощи кранов перераспредел етс между основной и запасной ветв ми трубопровода . Теплообменник предназначен дл поддержани посто нной температуры газа в трубопроводе. Регул торы давлени обеспечивают посто нство давлени в трубопроводе вне зависимости от установившейс температуры .which, with the help of cranes, is redistributed between the main and backup branches of the pipeline. The heat exchanger is designed to maintain a constant gas temperature in the pipeline. The pressure regulators ensure that the pressure in the pipeline is constant regardless of the established temperature.
Предмет изобретени Subject invention
Стенд дл градуировки и поверки расходомеров газа, содержащий замкнутый трубопровод с образцовым и повер емым расходомерами и устройства дл поддержани определенных параметров рабочей среды, отличающийс тем, что, с целью расширени рабочего диапазона тарировки и возмол ности непрерывной работы с заданными параметрами потока , он выполнен в виде двухконтурного тру бопровода с трем ветв мп, в одной из которых установлена воздуходувка и теплообмеппый аппарат, в другой - повер емый и образцовый расходомеры и исполнптельный орган , в третьей - исполнительный орган, перекрывающий ветвь в момент открыти исLiA bench for calibration and calibration of gas flowmeters, containing a closed pipeline with exemplary and verifiable flowmeters and devices for maintaining certain parameters of the working medium, characterized in that in order to expand the working range of calibration and to allow continuous operation with specified flow parameters the form of a double-circuit pipe with three branches of MP, one of which has a blower and a heat suppressor device, the other has a rotatable and exemplary flow meter and executive device, in the third, an executive body that overlaps the branch at the time of opening the Li
