Изобретение относится к устройствам запорно-регулирующей арматуры, применяемой при высокотемпературных параметрах рабочей среды, имеющей минимальные гидравлические потери с повышенной надежностью и герметичностью. Цель изобретения - снижение гидравлического сопротивления, повышение надежности и герметичности. Для осуществления этой цели заглушка и заслонка 17 снабжены уплотнительными элементами 16 и 18, поочередно и попарно контактирующими с уплотняющими элементами 15 и 19, a конфузоры расположены во внутреннем объеме заслонки 17. Перекрытие двойным уплотнением газохода и внутреннего объема устройства позволяет обеспечить высокую эксплуатационную надежность герметизации как газохода, так и механизмов внутреннего объема устройства, снижает гидравлические потери, резко уменьшает перегрев внутреннего объема устройства, предотвращает воздействие горячего газового потока на поднятую вверх заглушку и, следовательно,повышает КПД устройства и срок его службы.

The invention relates to devices for shut-off and control valves used at high-temperature parameters of the working environment, having minimal hydraulic losses with increased reliability and tightness. The purpose of the invention is the reduction of hydraulic resistance, increasing reliability and tightness. To achieve this, the plug and shutter 17 are equipped with sealing elements 16 and 18, alternately and in pairs in contact with the sealing elements 15 and 19, and the confusers are located in the internal volume of the valve 17. Overlapping with a double gas duct seal and the internal volume of the device allows for high operational reliability of sealing as gas duct, and the mechanisms of the internal volume of the device, reduces hydraulic losses, dramatically reduces overheating of the internal volume of the device, prevents exposure hot gas flow to the raised plug and, therefore, increases the efficiency of the device and its service life.
