氣活塞蝴蝶閥

氣動活塞蝴蝶閥是工業流體控制領域的高效執行器。它整合了氣動致動和蝴蝶閥結構的優勢，它利用活塞型氣缸作為電源。壓縮空氣推動活塞來回移動，驅動閥桿和蝴蝶盤以旋轉以進行打開和關閉的控制。它的核心結構具有偏心設計（例如單子裡，雙重或三重份），使蝴蝶盤和座椅在關閉時可以形成緊密的密封對。密封性能可以達到零洩漏標準，使其適合各種工作條件，包括截止，調節或節流。

與傳統的隔膜圓柱體相比，活塞型氣缸具有更強的推力輸出和負載電阻，特別適合在高壓差分和大直徑管道中控制介質（DN50-DN2000）。圓柱體的內部通常塗有耐磨物材料或用抗腐蝕措施處理的。結合防塵密封圈，它可以在塵土飛揚，潮濕或腐蝕性環境中穩定運行。可以通過調節圓柱體的進氣流來精確控制閥門的開口和關閉時間。借助定位器，它可以以0°至90°的角度實現流量調節，響應速度為0.5到3秒，滿足自動控制系統的高精度要求。
這種類型的閥門被廣泛用於諸如供水和排水處理，污水處理廠，熱管道和冶金式噴速爐燃氣管道等方案中。例如，在污水處理系統中，氣體活塞蝴蝶閥可以迅速切斷污水流量並與PLC控制系統結合使用完整的過程自動化。在熱管道中，它們可以通過精確調節蒸汽流來控制加熱溫度。它的模塊化設計有助於維護，因為可以拆卸圓柱體和閥體，並獨立替換，從而降低了維護成本。當結合ATEX認證的防爆炸缸時，它可以滿足易燃和爆炸性環境（例如石化行業）的安全要求，這使其成為現代工業自動化中流體控制的理想選擇。
