楔塞无润滑旋塞阀
WEDGEPLUG NON-LUBRICATED PLUG VALVE

　　楔塞阀结构符合API标准599和API标准600，可适用于并通过API 598测试。
　　Wedgeplug valves are designed to conform to API Standard 599 and API Standard 600 where applicable and are tested to API 598.

楔板扭矩
WEDGE TORQUE

　　操作机构 - 专利技术的机械操作机构，提升，旋转四分之一转，将阀塞重新放置在保护阀座表面。操作机构自动补偿磨损和各种操作环境。这使得金属阀塞在开启和关闭位置能够通过扭矩进入阀座里。操作机构的部件采用高强度钢制造，经过热处理，具有最好的抗磨损性能。请参阅公告WT 597.
　　Operators - Patented mechanical operators lift, rotate a quarter-turn, and reseat the plug on its protected seating surfaces. The operators automatically compensate for wear and varied operating conditions. They allow metal plugs to be seated by torque in both open and closed positions. Operator members are made from high-strength steel, heat treated for maximum wear resistance. See Bulletin WT 597.

操作机构
OPERATORS

　　可以采用扳手，手轮，或蜗轮等操作机构来操作阀门。对于扳手操作阀门，扳手是标准配置。在手轮的轮缘底部配置铸造的手掌把手，并用帽螺丝和锁紧垫圈加以紧固。蜗轮类型的齿轮操作机构完全封闭在外壳内。也可提供电动、液动和气动执行机构。对于电机操作机构，齿轮箱配置标准安装法兰。
　　Valves are operated by wrenches, handwheels, or worm gears. Wrenches are furnished standard with wrench operated valves. Handwheels have finger grips cast on bottom of rim and are fastened with a cap screw and lock washer. Worm-type gearing is completely enclosed in a housing. Valve opens by turning the handwheel counterclockwise. Electric, hydraulic and pneumatic actuation is also available. For motor operation the gear box is provided with standard mounting flanges.

　　阀体 - 当阀塞位于开启或关闭位置时，阀体内的凸面阀座表面受到保护。阀座表面在精密磨床上经过研磨，使其达到镜面光洁度。所有通径的阀门都配置七个凸起部，用于排气，排水和旁路连接。底部的凸起部位配置已经攻丝的标准管道螺纹。许多楔塞阀都配置整体铸造翼肋。这些翼肋再相关的点上增加了强度，对阀门铸件特别有利。
　　Body—Raised seating surfaces in bodies are protected when plug is in either open or closed position. Seating surfaces are ground to a mirror-like finish on precision grinding machines. All sizes have seven bosses on body for bleed, drain, and bypass connections. The bottom boss is furnished tapped with standard pipe threads. Many Wedgeplugs are supplied with integrally cast ribs. These ribs supply additional strength at the points most beneficial to the valve casting.
　　尺寸，钻孔和定位面端口法兰符合ANSI B16.5. 面对面尺寸符合ANSI B16.10, 包括短型，常规和圆型全端口阀门，除了具体网页上有特别规定以外。
　　Dimensions, drilling and spot-facing end flanges conform to ANSI B16.5. Face-to-face dimensions conform to ANSI B16.10, covering short pattern, regular and round full port valves except as noted on the catalog pages.
　　可以根据要求提供螺纹或对焊端口阀门的报价。
　　Threaded or butt-weld end valves may be quoted on application.

端口开启类型
TYPES OF PORT OPENINGS

　　类型7 - 70%端口开启度，特别适用于需要小压降的应用场合。
　　Type 7 - 70% port opening, particularly suitable where small pressure drop is desirable
　　类型9 - 90%端口开启度，适用于需要很小压降的应用
　　Type 9 - 90% port opening suitable for very small pressure drop
　　类型0 - 全圆形端口开启度，压降损失最小。
　　Type 0 - Full round port opening offering minimum pressure loss conditions.

　　楔塞硬面 - 楔塞阀的阀塞和阀体阀座上的硬面能够满足用户的要求。
　　阀塞和阀体阀座表面先由沉积层形成，然后经过机加工制成镜面光洁度表面。所采用的硬面材料保留自身的耐磨特性，抗腐蚀性能，和超高温下的硬度。配置硬面的楔塞钢阀门建议用于高温腐蚀和侵蚀性蒸汽和油，或油蒸汽应用。在低温应用环境下，配置硬面的阀门也适用于严酷的应用环境。奥氏不锈钢阀门的阀塞通常也采用相同的材料。常用的硬面包括钨铬钴合金和Ultimet™材料。
　　Wedgeplug Hard Facings—Hard facings on the plug and body seats of Wedgeplug valves can be furnished to customer requirements.
　　The facing is deposited on the plug and body seats and is then machined to a mirror-like surface. The hard facing materials used retain their wearing qualities, corrosion resistance, and hardness at extremely high temperatures. Wedgeplug steel valves with hard facings are recommended for high temperature corrosive and erosive steam and oil or oil vapor services. Valves with hard facings are also suitable for severe services at low temperatures. Plugs in austenitic stainless steel valves are regularly furnished in this material.Typical hardfacing includes Stellite™ and Ultimet™.
　　阀塞 - 阀塞选用具有无磨痕特性的材料铸造而成。根据需要可提供特殊材料。阀塞锥度确保紧密密封和操作轻松。
　　Plug - Plugs are cast from materials selected for their non galling characteristics. Special metals are available on application. Plug taper assures a tight seal and ease of operation.
　　阀杆 - 高强度不锈钢阀杆经过精密机加工。直径大确保强度。特殊订单可配置其他合金材料。对于高压差和特殊安装，可提供附加在阀塞的底部轴颈和平衡杆。
　　Stem - High strength stainless steel stems are accurately machined. Large diameter assures strength. Other alloys are available on special order. Trunnions and balance stems, attached to the bottom of the plug, are available for high differential pressures and special installations.
　　位置指示器 - 指示器显示阀塞是处于开启或关闭状态，并显示阀塞在90^o旋转范围内的状态。指示器可以很容易从远程观察。当阀门处于远程时，位置指示器可用于微动开关接触装置。
　　Position Indicator - indicators show whether plug is open or closed and provide a visual indication of the 90^o rotation of plug. Indicators can be easily seen from a distance. On valves controlled remotely, the position indicators may be used for microswitch contact.
　　轭架阀盖 - 轭架阀盖采用合金钢铸造而成。根据要求，可提供特殊合金材料的轭架。可采用外螺纹和内螺纹，或环类型连接阀体-阀盖连接方式。较大型阀门的结构是分离式轭架和阀盖。
　　Yoke Bonnet —Yoke Bonnets are cast from alloy steels. Special alloys are available on order. Male and female or ring type joint body-bonnet connections are utilized. Larger valves are designed with separate yokes and bonnets.
