Description
Дл уменьшени вли ни массы корпуса 6 термочувствительные элементы устанавливают в пластине 7, изготовленной из материала с низкой теплопроводностью.To reduce the influence of the mass of the housing 6, temperature-sensitive elements are mounted in a plate 7 made of a material with low thermal conductivity.
К концам биметаллических пластин присосдинены контакты 8 и 9, На зонде 4 установлен нагреватель 10.Contacts 8 and 9 are attached to the ends of the bimetallic plates. Heater 10 is mounted on the probe 4.
Сигнализатор потока работает следующим образом.The flow detector works as follows.
Часть сигнализатора с выступающими зондами 2 и 4 помещают в трубе (коробе), в которой протекает поток контролируемой жидкости (газа). При этом оба зонда расположены таким образом, чтобы они одинаково обтекались потоком и не экранировали друг друга .A portion of the detector with protruding probes 2 and 4 is placed in a pipe (box) in which a stream of controlled liquid (gas) flows. In this case, both probes are arranged in such a way that they are equally flown around the stream and do not shield each other.
Тепло, создаваемое нагревателем 1, уноситс потоком жидкости или газа, вследствие чего температура биметаллической нластииы 3 увеличиваетс незначительно и рассто ние между контактами 8 и 9 остаетс без изменени . При прекращении или снижении скорости потока жидкости (газа) термобиметаллическа пластина 3 быстро нагреваетс , вследствие чего она изгибаетс , контакты 8 и 9 замыкаютс и выдают сигнал аварии.The heat generated by the heater 1 is carried away by the flow of a liquid or gas, as a result of which the temperature of the bimetallic plastic 3 increases slightly and the distance between contacts 8 and 9 remains unchanged. Upon termination or reduction of the flow rate of the liquid (gas), the thermo-bimetallic plate 3 heats up quickly, as a result of which it bends, contacts 8 and 9 are closed and give an alarm signal.
При восстановлении потока в контролируемой трубе зонд 2, а следовательно, и биметаллическа пластина 3 остывают, и контакты 8 и 9 размыкаютс .When the flow in the controlled pipe is restored, the probe 2, and hence the bimetallic plate 3, cools down, and the contacts 8 and 9 open.
Мен напр жение питани электронагревател 1, рассто ние между зондами, а также устанавлива необходимое напр жение питаии нагревател 10 от нул до максимального значени , можно обеспечить сигнализацию в широком диапазоне скоростей контролируемого потока и выбор необходимой точки срабатывани .The power supply voltage of the electric heater 1, the distance between the probes, as well as setting the required supply voltage of the heater 10 from zero to the maximum value, can provide an alarm in a wide range of controlled flow rates and select the desired trigger point.
