(1) 轭架套管 –铝青铜轭架套管*大程度减少操作扭矩。较大通径的截止阀配置针形轴承类型的止推轴承。 (1) Yoke Sleeve– aluminum-bronze yoke sleeve minimizesoperating torque. Larger sizes have needle bearing type thrustbearings.
(2) 阀杆 – 精密底面阀杆配置倒置T形头,使得阀杆与楔体连接更加稳定可靠。 (2) Stem – precision-ground stem has upset tee-head for reliable stem/wedge connection.
(3) 压力密封 –结构简单,分段扣环,镀银低碳钢垫圈,有助于拆卸和*大限度的阀帽密封。 (3) Pressure Seal– uncomplicated design has segmentedretaining ring and mild steel silver plated gasket to aiddisassembly and provide maximum bonnet seal.
(4) 硬化的阀座表面 – 阀瓣和阀体地阀座表面都经过表面硬化,*大限度延长使用寿命。 (4) Hardened SeatingSurfaces – both disc and bodyseating surfaces are hard faced for maximum service life.
(5) 阀体 –流线形流道,*大限度减少压降。对焊、缩喉管或法兰连接端口几种可供选择的连接方式。 (5) Body – streamlined flow path minimizes pressure drop. Butt weld, venturi or flanged ends provide piping alternatives.
(6) 执行机构 –这些阀门可以配置电动、液动或气动执行机构。DN350以下的标准配置是手动执行机构。 (6) Actuators– valves can be supplied with any type ofelectric, hydraulic or pneumatic actuator. Standard manualactuators are handwheels through 14".
(7) 轭架 – 完全装配式轭架通过抗震测试,易于维护和安装执行机构。 (7) Yoke – fully fabricated yoke is seismically qualified while offering easy maintenance and actuator mounting.
(8) 压盖 – 两件式,自行调整压盖,不需要配置压簧杆。便于维护的转位式螺栓。 (8) Gland– two piece, self-aligning gland eliminatescocking. Swing out bolting facilitates maintenance.
(9) 螺栓轭架 – 轭架是通过螺栓安装在阀体上。 (9) Bolted Yoke– yoke is bolted to body.
(10) 整体后座– 硬面,使用寿命*长。 (10) IntegralBackseat – hardfaced formaximum backseat life.
(11) 阀瓣 – 全程阀体导向,是阀座更加适用于高压应用环境。 (11) Disc– fully body guided for perfect seating inhigh pressure services.
