Изобретение относитс к устройствам дл контрол уровн в емкости с криогенной жидкостью и может быть использовано в авиационной и химической промышленност х.The invention relates to a device for monitoring the level in a tank with a cryogenic liquid and can be used in the aviation and chemical industries.
Известны устройства дл контрол уровн в емкост х с криогенной жидкостью, содержащие чувствительный элемент и вторичный прибор. У таких устройств температура газа поддува вли ет на контроль уровн .Level control devices in cryogenic liquid tanks are known that contain a sensing element and a secondary device. With such devices, the temperature of the gas blowing will affect the level control.
С целью упрощени устройства в нем чувствительный элемент выполнен в виде вертикально укрепленного внутри емкости тонкостенного трубчатого витого теплообменника , на выходе которого установлены спаи дифференциальной термопары, св занной с вторичным прибором, и вход теплообменника через регул тор расхода сообщен с источником теплоносител , а выход - с внешней средой . В качестве теплоносител использован газ наддува, отбираемый из емкости.In order to simplify the device, the sensing element is designed as a thin-walled tubular twisted heat exchanger vertically fixed inside the tank, at the output of which the junctions of the differential thermocouple connected to the secondary device are installed, and the heat exchanger input through the flow regulator is connected to the heat source and external environment. A pressurized gas taken from the tank was used as the coolant.
На чертеже схематично изображено устройство дл контрол уровн жидкости.The drawing schematically shows a device for controlling the level of a liquid.
Предлагаемое устройство содержит емкость 1, теплообменник 2, дифференциальную термопару 3, вторичный прибор 4 и регул тор газа 5.The proposed device contains a tank 1, a heat exchanger 2, a differential thermocouple 3, a secondary device 4 and a gas regulator 5.
Газ, отбираемый из источника, проходит последовательно через регул тор расхода 5, теплообменник 2. В последнем в зависимостиThe gas taken from the source passes sequentially through the flow regulator 5, heat exchanger 2. In the latter, depending on
от уровн жидкости в емкости 1 газ охлаждаетс и сбрасываетс в атмосферу.from the liquid level in the tank 1, the gas is cooled and discharged into the atmosphere.
Показани дифференциальной термопары 3, измер ющей разницу входной и выходной температур газа, регистрируютс на вторичном приборе 4, при помощи которого производитс контроль уровн жидкости и емкости. Посто нный расход газа через теплообменник 2 поддерживаетс регул тором 5 дл исключени конденсации на стенках теплообменника . В качестве теплоносител быть использован газ, имеющий температуру ожижеии более низкую, чем температура криогенной жидкости в емкости.The indications of a differential thermocouple 3 measuring the difference between the inlet and outlet temperatures of the gas are recorded on the secondary device 4, which is used to monitor the level of the liquid and the capacitance. The constant flow of gas through the heat exchanger 2 is maintained by the regulator 5 to prevent condensation on the walls of the heat exchanger. As a heat carrier, gas having a liquefaction temperature lower than the temperature of the cryogenic liquid in the tank should be used.
