Изобретение относитс к автоматизации контрол качества продуктом химической и нефтехимической отраслей промышленности, а именно к автоматизации контрол температуры разм гчени битумов и подобных ему материалов.This invention relates to the automation of product quality control in the chemical and petrochemical industries, in particular to the automation of the control of the softening temperature of bitumens and similar materials.
Известны устройства дл измерени температуры разм гчени битумов, содержащие наполн емую пробой битума кювету с нагревателем , измеритель температуры битума, узел создани давлени на пробу и индикатор давлени , подключенный к выходу кюветы.Devices for measuring the softening temperature of bitumens are known, comprising a cuvette filled with a bitumen breakdown with a heater, a bitumen temperature meter, a sample pressure generating unit and a pressure indicator connected to the cell outlet.
Цель изобретени - повышение точности измерени и упрощение конструкции устройства .The purpose of the invention is to improve the measurement accuracy and simplify the design of the device.
Дл этого индикатор давлени снабжен автоматическим клапаном, сообщающим полость индикатора с атмосферой, и блоком фиксации импульсов давлени , св занным с измерителем температуры.For this, the pressure indicator is equipped with an automatic valve, which communicates the cavity of the indicator with the atmosphere, and a pressure pulse fixation unit connected to the temperature meter.
На чертеже изображено описываемое устройство дл измерени температуры разм гчени битумов.The drawing shows the described device for measuring the softening temperature of bitumens.
Устройство содержит измерительную кювету 1, например, U-образную трубку, в которой после заливки пробы образуютс полости 2 и 3, источник 4 посто нного давлени , например сильфон 5, нагруженный эксцентрично сид щим на оси кулачком 6, нагреватель 7,The device contains a measuring cuvette 1, for example, a U-shaped tube, in which, after the sample has been poured, cavities 2 and 3 are formed, a constant pressure source 4, for example a bellows 5, a cam 6 eccentrically loaded on an axis, a heater 7,
датчик 8 температуры, подключенный ко входу вторичного измерительного прибора 9, манометр 10, состо щий из измерительной полости 11, чувствительного элемента 12, например мембраны, автоматического клапана 13 с приводом в виде электродвигател 14 и кулачка 15, мембрана 12 имеет электрические контакты 16, исполнительный механизм 17, например реле.a temperature sensor 8 connected to the input of the secondary measuring device 9, a pressure gauge 10 consisting of a measuring cavity 11, a sensing element 12, for example a diaphragm, an automatic valve 13 driven by an electric motor 14 and a cam 15, the membrane 12 has electrical contacts 16, the actuator mechanism 17, for example a relay.
Определение температуры разм гчени битумов с помощью предлагаемого устройства происходит следующим образом.The determination of the softening temperature of bitumens using the proposed device is as follows.
Контролируемый продукт, нагретый до легкоподвижного состо ни , заливают в измерительную кювету 1, выполненную в виде U-образной трубки. После застывани образца измерительна кювета оказываетс разделенной на две полости 2 и 3. Одну из полостей измерительной кюветы 1, например полость 2, соедин ют с источником 4 посто нного давлени , а другую полость, например полость 3 - с измерительной полостью 11 маномера 10. После этого измерительную кювету 1 помещают в нагреватель 7 и подвергают нагреву с заданной посто нной скоростью.The controlled product, heated to a very mobile state, is poured into measuring cell 1, made in the form of a U-shaped tube. After solidification of the sample, the measuring cuvette is divided into two cavities 2 and 3. One of the cavities of the measuring cuvette 1, for example, cavity 2, is connected to a source 4 of constant pressure, and another cavity, for example cavity 3, to measuring cavity 11 of the manomer 10. After This measuring cell 1 is placed in the heater 7 and subjected to heating at a given constant speed.
Температуру пробы непрерывно измер ют датчиком 8 температуры и автоматически записывают на диаграмме вторичного измерительного прибора 9.The temperature of the sample is continuously measured by the temperature sensor 8 and automatically recorded in the diagram of the secondary measuring device 9.
