Description
Изобретение относитс к измерительной технике и может быть использовано дл контрол уровн жидкости в тепловых трубах, термосифонах, испарительно-конденсационных устройствах , холодильных установках и т.д.The invention relates to a measurement technique and can be used to control the level of a liquid in heat pipes, thermosyphons, evaporative condensation devices, refrigeration units, etc.
Известен способ контрол уровн жидкости в сосуде путем теплового воздействи на сосуд и регистрации теплового эффекта с помощью термочувствитёльного элемента. Дл этого в сосуд с жидкостью помещают нагреваемый полый кожух, на котором размещена термопара, один слой которой поме .щаетс на контролируемом уровне, а второй - выше уровн жидкости. При выходе спа из-под жидкости ЭДС тер- мопары падает до нул , что позвол ет контролировать уровень жидкости в сосуде t1.There is a known method for controlling the level of a liquid in a vessel by means of thermal action on the vessel and recording the thermal effect with the help of a temperature-sensitive element. For this purpose, a heated hollow casing is placed in a vessel with liquid, on which a thermocouple is placed, one layer of which is placed at a controlled level, and the second is above the liquid level. When the spa leaves the liquid, the emf of the thermocouple falls to zero, which allows to control the level of liquid in the vessel t1.
Недостатком известного способа вл етс необходимость установки подогреваемого кожуха внутрь сосуда, что делает невозможным его использование дл контрол уровн жидкости в труднодоступных объектах, например в центральных силовых трубах многотрубчатого теплообменника с малым рассто нием между трубами.The disadvantage of this method is the need to install a heated casing inside the vessel, which makes it impossible to use it to control the liquid level in hard-to-reach objects, for example, in central power pipes of a multi-tubular heat exchanger with a small distance between the pipes.
Цель изобретени - контроль уровн жидкости в труднодоступных объектах .The purpose of the invention is to control the level of liquid in hard-to-reach objects.
с Указанна цель достигаетс тем, что согласно способу контрол уровн легкоиспар ющейс жидкости в закрытом сосуде путем теплового воздействи на сосуд и регистрации тепловогоThis goal is achieved by the fact that, according to the method of controlling the level of an easily evaporating liquid in a closed vessel, by thermal action on the vessel and recording the thermal
IQ эффекта с помощью термочувствительного элемента, осуществл ют вертикальное перемещение локального нагревател вдоль внешней стенки сосуда и регистрируют изменение температура свободного от жидкости конца сосуда. IQ effect using a temperature-sensitive element, the local heater is vertically displaced along the external wall of the vessel, and the change in temperature of the liquid end of the vessel is recorded.
15 Контроль уровн осуществл ют следующим образом.15 Level controls are carried out as follows.
