Description
В р де случаев возникает потребность в измерении паросодержани потока. Известные способы измерени паросодержани , основанные на калориметрировании, дросселировании или других методах, вл ютс или громоздкими, или ограниченными по пределам измерени , или имеют недостаточную точность. Кроме того, большинство из этих способов непригодно дл измерени в нестационарных услови х.In a number of cases, the need arises to measure steam flow. The known methods for measuring steam content, based on calorimetry, throttling or other methods, are either cumbersome, or limited in terms of measurement, or have insufficient accuracy. In addition, most of these methods are unsuitable for measurement in non-stationary conditions.
Известно также применение шайбы и напорной трубки в качестве измерительных приборов в паропроводах, используемых обычно дл однофазной среды с известным удельным весом.It is also known to use a washer and pressure tube as measuring devices in steam lines, usually used for single-phase media with a known specific gravity.
В описываемом способе влагосодержание паровод ной смеси определ ют по измерению перепада давлени , создаваемого установленной в трубе шайбой, и по измерению динамического напора в напорной трубке, расположенной в потоке паровод ной смеси последовательно с шайбой. Такой способ значительно упрош,ает и повышает надежность определени содержани капельной влаги в смеси.In the described method, the moisture content of the water-steam mixture is determined by measuring the pressure drop created by the washer installed in the pipe and by measuring the dynamic pressure in the pressure pipe located in the steam-water mixture flow in series with the washer. This method significantly simplifies and increases the reliability of determining the moisture content of the mixture in the mixture.
На чертеже показана схема установки приборов в трубопроводе.The drawing shows the installation diagram of the devices in the pipeline.
В паропроводе / вмонтированы последовательно шайба 2 и напорна трубка 3. По отношению перепада давлени на шайбе h к перепаду давлени на напорной трубке определ ют паросодержание и влагосодержание смеси.A washer 2 and a pressure tube 3 are installed in series in the steam line / in series. The steam content and moisture content of the mixture are determined by the ratio of the pressure drop across the washer h to the pressure drop across the pressure tube.
Такой способ определени паросодержани и влагосодержани паровод ной смеси вл етс целесообразным в том случае, когда расход паровод ной смеси неизвестен. В тех случа х, когда расход паровод ной смеси известен, задача измерени паросодержани суш,ественно упрощаетс . Дл этого достаточно установить в трубопроводе либо напорную трубку, либо шайбу.Such a method for determining the steam content and moisture content of the steam-water mixture is appropriate in the case when the consumption of the steam-water mixture is unknown. In cases where the consumption of the steam / water mixture is known, the task of measuring the steam content of the sushi is simplified significantly. To do this, it is enough to install either a pressure pipe or a washer in the pipeline.
Предмет изобретени Subject invention
Способ определени влагосодержани паровод ной , пррт-екаюшвй по трубопроводу, отличающийс тем, что, с целью упрощени и повышени надежности определени , замер ют перепад давлени , создаваемый установленной в трубопроводе шайбой, и динамический напор в напорной трубке, расположенной в потоке паровод ной смеси последовательно с шайбой, и по найденным величинам определ ют содержание влаги в смеси.The method of determining the moisture content of the steam-water system, which is produced through a pipeline, is characterized in that, in order to simplify and increase the reliability of the determination, the pressure drop created by the washer installed in the pipeline and the dynamic pressure in the pressure pipe located in the steam-steam mixture are measured with a washer, and the moisture content in the mixture is determined from the values found.
