Description
(54) УСТРОЙСТВО ДЛЯ КОНТРОЛЯ НАЛИЧИЯ ПЛАМЕНИ В ТОПКАХ(54) DEVICE TO CONTROL AVAILABILITY OF FLAME IN FOODS
1one
Изобретение относитс к теплоэнергетике, а именно к автоматизации контрол пламени в топках.The invention relates to a power system, in particular to the automation of flame control in furnaces.
По основному авт. св. № 408107 известно устройство дл контрол наличи пламени в топках, содержащее чувствительный элемент , включенный в одно из плеч пневматического моста, усилитель и исполнительный механизм, соединенный с клапаном-отсекателем подачи топлива, причем чувствительный элемент выполнен в виде капилл ра и закреплен в кожух с отверсти ми дл его охлаждени 1.According to the main author. St. No. 408107, a device for controlling the presence of a flame in furnaces is known, which contains a sensing element included in one of the arms of the pneumatic bridge, an amplifier and an actuator connected to the fuel supply shut-off valve, the sensing element being in the form of a capillary and fixed in a casing with an opening mi to cool it 1.
Однако известное устройство недостаточно надежно.However, the known device is not reliable enough.
Целью изобретени вл етс повышение надежности устройства.The aim of the invention is to increase the reliability of the device.
Поставленна цель достигаетс тем, что в устройство дополнительно введены логический элемент И и второй элемент сравнени с подпором, входы которого соединены соответственно со входами первого элемента сравнени , а выходы обоих элементов сравнени соединены с логическим элементом И, который соединен со входом усилител .The goal is achieved by additionally inputting a logical element AND and a second comparison element with a support, whose inputs are connected respectively to the inputs of the first comparison element, and the outputs of both comparison elements are connected to an AND logical element that is connected to the amplifier input.
На чертеже представлена блок-схема устройства, содержаща пневматическийThe drawing shows a block diagram of a device comprising a pneumatic
мост, образованный дроссел ми 1-3 и чувствительным элементом 4, усилитель 5 с элементом сравнени 6, исполнительным механизмом 7 с регулирующим органом 8, причем устройство дополнительно содержит 5 элемент И 9 и элемент сравнени 10.the bridge formed by the throttles 1-3 and the sensitive element 4, the amplifier 5 with the element of comparison 6, the actuator 7 with the regulator 8, and the device additionally contains 5 element And 9 and the element of comparison 10.
Устройство работает следующим образом.The device works as follows.
Ввиду того, что дополнительный элемент сравнени 10 имеет величину и знак подпора, обеспечивающие при нормальных режимах 10 работы топки на выходах логического элемента И 9 единичный сигнал, при погасании пламени или перегаре чувствительного элемента 4 в пневматическом мосту перераспределени давлений формируетс нулевой сигнал на выходах основного 6 и дополнительного 10 элементов сравнени , что приводит к срабатыванию устройства контрол и топливо отсекаетс от горелки.Due to the fact that the additional element of comparison 10 has the magnitude and sign of the backwater, providing during normal operating modes 10 of the firebox at the outputs of the logic element AND 9 a single signal, when the flame goes out or the fumes of the sensing element 4 in the pneumatic pressure redistribution bridge, a zero signal is generated and an additional 10 reference elements, which triggers the control device and the fuel is cut off from the burner.
