Abstract

Przepustnica do szczelnego odcinania przepływu niskociśnieniowych mediów gazowych w przewodach o dużej powierzchni poprzecznego przekroju kołowego lub prostokątnego charakteryzuje się tym, że na obwodzie dysku roboczego (12) trwale umocowane jest korytko (2) wsporcze, w którym umieszczona jest uszczelka (16) o obwodzie zamkniętym wykonana z elastycznej rurki z tworzywa odpornego na temperaturę, a z uszczelki wyprowadzony jest króciec zasilający (15), który przez kanalik (19) i kanalik powietrzny (17) połączony jest zaworem trójdrożnym (18) z dopływem D sprężonego powietrza lub alternatywnie z odpływem O do otoczenia.The throttle for tight shut-off of the flow of low-pressure gaseous media in conduits with a large cross-sectional area of circular or rectangular cross-section is characterized by the fact that a support tray (2) is permanently fixed on the circumference of the working disc (12), in which a gasket (16) with a closed circuit is placed made of a flexible pipe made of temperature-resistant plastic, and a supply connector (15) is led out of the gasket, which is connected through a duct (19) and an air duct (17) with a three-way valve (18) with the compressed air inlet D or alternatively with the outflow O to environment.
