- The high capacity accelerator assures quick valve response to the solenoid signal regardless of the main valve size. 這種高性能加速器確保閥門能夠迅速反應電磁閥信號,而與主閥通徑無關。
- Supply power to sootblower, push down start button, the main valve will open and close automatically. 對電動機、行程開關應有保護裝置。經過載能自動跳閥,並向主控制室報警。
- The main valve spindle incorporates an inner spindle for double regulation memory stop and valve position setting. 主閥軸配置一個內軸,適用於雙重調節止動記憶和閥門位置設置。
- Where service conditions warrant larger-than-standard by-passes, it is recommended that the installation of the by-passes be around the main valve. 在應用條件允許安裝較大的旁路的地方,建議旁路的安裝要環繞著主閥門。
- General requirements to the procedure design: 1. Supply power to sootblower, push down start button, the main valve will open and close automatically. 對程序控制設計的一般要求是:1、接通線路電源開關,電源開啟后,只需按起動按鈕,吹灰管道的總閥即以自動開啟、關閉;各吹灰器能按固定程序或選擇程序一個個地或成組順序動作,進行吹灰;吹灰結束后,總閥能自動關閉。
- For snap action, the main valve opens rapidly at set pressure and achieves rated relieving capacity at relieving pressure. 對於快動式先導器,主閥門在達到設定壓力時快速打開並且在泄放壓力時達到額定排放量。
