美国太平洋阀门
     

按照严酷的日常应用要求制造
Making The Severe Routine

  楔塞阀将最严酷的侵蚀性和最困难的金属阀座密封应用到日常的应用中。这主要归功于阀门结构简单化和80多年的创新开发历史,满足了日益增加的生产工艺液流处理的要求。
  Wedgeplug turns the most severely erosive and difficult metal seated sealing services into routine applications. This is attributable to the valve’s design simplicity and to its 80 plus years of evolution in meeting increasingly demanding process requirements.

楔塞阀的主要特点包括
Wedgeplug’s key features include:

  • 结构简单,只有三个主要部件
    Simple construction with only three major parts
  • 简单的清洗备选件
    Simple purge options
  • 金属密封表面
    Metal sealing surfaces
  • 双向密封,具有双重堵塞和排泄能力
    Bi-directional sealing with double block-and-bleed capability
  • Wedgetorque操作机构
    Wedgetorque operation

结构简单化
Design Simplicity

  阀体配置双重、整体金属阀座,提供金属对金属、双向管道密封。这种凸面阀座在全开或阀塞覆盖阀体阀座而关闭时,能够完全避免生产工艺液流进入阀体内。没有空穴可让工艺液流淤积,阀座后没有泄漏通道,没有热膨胀问题。具有内在的防火消防安全性,一个楔塞阀就拥有堵塞和排放双重应用功能。连接端口包括:凸面,环连接和平面法兰,对焊,螺纹连接端口,承插焊,和Grayloc®插口。
  The body features dual, integral metal seats which provide metal-to-metal, bi-directional line sealing. The raised seats are completely protected from the process flow when fully open or plug covering body seat closed. There are no cavities to permit process build-up, no leak paths behind the seat and no thermal expansion problems. Inherently fire safe, a single Wedgeplug valve provides double block-and-bleed service. End connections include: raised face, ring joint and flat face flanges; butt weld; screwed ends; socket weld; and Grayloc® hub.

阀塞
Plug

  锥形阀塞经过精密研磨,采用硬化高合金材料或一种镀层不锈钢,确保紧密密封和操作容易。硬化和镀层表面可以抵抗法门操作期间的大多数严酷的表面损坏,预计使用寿命长达多年。
  The tapered plug is precision ground from hardened high alloy material or an overlaid stainless to assure a tight seal and easy operation. The hardened or overlaid surfaces resist damage from the most severe surface during operation of the valve for years of predictable service.

阀座
Seats

  楔塞阀独特的提升和旋转操作使得阀门的工作实际上没有摩擦或接触到阀座和阀塞。由于在提升和旋转期间没有产生接触,因此在阀门全开和全闭时,阀座就不会受到工艺液流的破坏,因此也就不需要在阀座表面进行镀层。阀座是作为阀体的一部分整体铸件,经过机加工,然后研磨成镜面光洁度以匹配阀塞形成紧密金属对金属密封。可根据用户的要求提供特殊的冶金和硬面表面,包括Stellite®和Ultimet®.
  The unique lift and turn operation of the Wedgeplug valve allows the valve to operate with virtually no rubbing or contact of the seats and plug. Since there is no contact during lift and turning and since the seats are protected from the process flow when the valve is either fully opened or closed, there is no need for overlays on the seats. The seats are integral cast as part of the body and are machined and then ground to a mirror-like finish to match the plug for tight metal to metal sealing. Special metallurgy and hard facing surfaces are available and can be furnished to customer request, including Stellite® and Ultimet®.

  顶部进入阀体允许在线拆卸和维修。阀塞-阀杆-轭架-执行机构可以拆卸作为单个装置进行检查、清洗和维修。这是很重要的成本节约和维护的优点,特别是对于通径DN300及以上的阀门更是如此。
  Top entry to the body allows in-line disassembly and repairability. Plug-stem-yoke-actuator can be removed as a single unit for inspection, cleaning and repair. This is a significant cost and maintenance benefit, especially for valve sizes 12 in (300 mm) and larger.

  备选件Q-阀塞提供全端口流道,而且重量轻,维护容易。其他优点还包括轴颈安装消除侧面负载,延长阀座使用寿命;正切清洗;和坚固耐用的安装轭架结构。
  The optional Q-plug provides full port flow along with less weight and easier maintenance. Other enhancements include trunnion mounting to eliminate side loads for prolonged seat life; tangential purge; and heavy-duty mounting yoke design.
