(1) 軛架套管 –鋁青銅軛架套管*大程度減少操作扭矩。較大通徑的截止閥配置針形軸承類型的止推軸承。 (1) Yoke Sleeve– aluminum-bronze yoke sleeve minimizesoperating torque. Larger sizes have needle bearing type thrustbearings. (2) 閥杆 – 精密底麵閥杆配置倒置T形頭,使得閥杆與(yu) 楔體(ti) 連接更加穩定可靠。 (2) Stem – precision-ground stem has upset tee-head for reliable stem/wedge connection. (3) 壓力密封 –結構簡單,分段扣環,鍍銀低碳鋼墊圈,有助於(yu) 拆卸和*大限度的閥帽密封。 (3) Pressure Seal– uncomplicated design has segmentedretaining ring and mild steel silver plated gasket to aiddisassembly and provide maximum bonnet seal. (4) 硬化的閥座表麵 – 閥瓣和閥體(ti) 地閥座表麵都經過表麵硬化,*大限度延長使用壽命。 (4) Hardened SeatingSurfaces – both disc and bodyseating surfaces are hard faced for maximum service life. (5) 閥體(ti) –流線形流道,*大限度減少壓降。對焊、縮喉管或法蘭(lan) 連接端口幾種可供選擇的連接方式。 (5) Body – streamlined flow path minimizes pressure drop. Butt weld, venturi or flanged ends provide piping alternatives. |  | (6) 執行機構 –這些閥門可以配置電動、液動或氣動執行機構。DN350以下的標準配置是手動執行機構。 (6) Actuators– valves can be supplied with any type ofelectric, hydraulic or pneumatic actuator. Standard manualactuators are handwheels through 14". (7) 軛架 – 完全裝配式軛架通過抗震測試,易於(yu) 維護和安裝執行機構。 (7) Yoke – fully fabricated yoke is seismically qualified while offering easy maintenance and actuator mounting. (8) 壓蓋 – 兩(liang) 件式,自行調整壓蓋,不需要配置壓簧杆。便於(yu) 維護的轉位式螺栓。 (8) Gland– two piece, self-aligning gland eliminatescocking. Swing out bolting facilitates maintenance. (9) 螺栓軛架 – 軛架是通過螺栓安裝在閥體(ti) 上。 (9) Bolted Yoke– yoke is bolted to body. (10) 整體(ti) 後座– 硬麵,使用壽命*長。 (10) IntegralBackseat – hardfaced formaximum backseat life. (11) 閥瓣 – 全程閥體(ti) 導向,是閥座更加適用於(yu) 高壓應用環境。 (11) Disc– fully body guided for perfect seating inhigh pressure services. |
