  • Level Indicators Using A Float (AREA)

Description

Известные фотоэлектрические сигнализаторы предельных уровней воды в барабане парового котла обычно содержат водоуказательную колонку с цилиндрическим поплавком, управл ющим подачей световых сигналов на фотоэлементы, включенные в цепь сигнализации об изменени х уровн .The known photoelectric alarms for the limiting water levels in the drum of a steam boiler usually contain a water indicating column with a cylindrical float that controls the light signals to the photocells included in the level change signaling circuit.

В предлагаемом фотоэлектрическом сигнализаторе число фотоэлементов уменьшено до одного, что упрощает его конструкцию и повышает надежность в работе.In the proposed photoelectric signaling device, the number of photocells is reduced to one, which simplifies its design and increases reliability in operation.

Поплавок сигнализатора имеет длину, равную рассто нию между предельными верхним и нижним уровн ми, и целиком погружен в воду с тем, чтобы он пропускал лучи света на фотоэлемент только при достижении водой в барабане котла указанных уровней.The indicator float has a length equal to the distance between the upper and lower levels, and is completely submerged in water so that it passes the rays of light onto the photocell only when water reaches the specified levels in the boiler drum.

На чертеже схематически изображен предлагаемый фотоэлектри ческий сигнализатор, который состоит из оптического датчика уровн  воды, фотореле и сигнального устройства.The drawing shows schematically the proposed photoelectric signaling device, which consists of an optical water level sensor, a photo relay and a signal device.

Оптический датчик уровн  состоит из колонки / с цилиндрическим поплавком 2 и окнами 3 и 4, источника света Л и фотоэлемента ФЭ. Колонка соединена с паровым и вод ным пространствами барабана котла. Окна 3 и 4 наход тс  на отметке минимального уровн  НУ. Поплавок 2, полностью погруженный в воду, плавает внутри колонки, выполн   роль .«светозаслонки, и имеет длину Н, равную рассто нию между контролируемыми уровн ми.The optical level sensor consists of a column / with a cylindrical float 2 and windows 3 and 4, a light source L and a PV photocell. The column is connected to the steam and water spaces of the boiler drum. Windows 3 and 4 are at the level of the minimum LC level. The float 2, completely immersed in water, floats inside the column, performs the role of a light valve, and has a length H equal to the distance between the levels being monitored.

В качестве источника видимого света датчик имеет лампу накаливани  // (маломощна  и низкого напр жени ), а в качестве приемнику света (фотоэлемента) - однокаскадныи фотоумножитель ФЭ или фотосопротивление . Луч света от лампы Л через окна 3 н 4 колонки / направл етс  на фотоэлемент ФР.As a source of visible light, the sensor has a glow lamp // (low power and low voltage), and as a light receiver (photocell) it is a single-stage PV photomultiplier or photoresistance. The beam of light from the lamp L through the windows of 3 n 4 columns / is directed to the photocell FR.

Фотореле.ФР - пр мого действи , двухступенчатое, однокаскадное, посто нного, тока.Photorelay. FR - direct action, two-stage, single-stage, direct, current.
