氣動高溫控制閥

氣動高溫控制閥是專門用於極端熱環境的專業流體控制設備,該設備廣泛用於工業過程,需要在高溫下進行精確調節。它們的核心優勢在於將氣動驅動系統與高溫抗性材料的整合,從而可以準確控制熱介質的流動,壓力或溫度(例如,蒸汽,高溫油,熔融金屬流體)。此設計可確保在惡劣的高溫條件下的可靠性和安全性。

氣動高溫控制閥的運行是基於“氣動動力驅動 +高溫結構設計”的雙重機制:
  • 氣動致動:壓縮空氣用作電源。控制信號(例如4-20mA電流或0.02-0.1MPA氣壓)調節對執行器的氣壓輸入,驅動閥桿移動並調整閥門插頭和座椅之間的開口。
  • 高溫適應:臨界組件(例如,閥體,塞子,波紋管)使用耐熱材料(例如,Hastelloy,Inconel,Inconel,陶瓷塗料)與熱絕緣設計(例如,雙層層,散熱器,散熱鰭/水槽鰭)。這樣可以防止高溫破壞密封和執行器,從而確保-30°C至70°C或更高的穩定運行。
氣動高溫控制閥結合了材料科學和控制技術,以作為高溫過程中效率和安全性的關鍵設備。他們的設計和應用必須與操作要求緊密相符,以確保精確的控制和長期可靠性。
