强化的操作性能和更长的阀门使用寿命
Enhance Performance and Extend Valve Life
为了保持协调一致的阀座密封性能和延长阀门的使用寿命，建议用户在每当操作阀门后都清洗和冲刷美国太平洋楔塞阀一次。通过清洗和冲刷，您能够：
To provide consistent seating performance and
prolonged valve life, it is recommended that you purge and flush your
Pacific Wedgeplug valve each time it is operated. By purging and flushing,
you can:
- 清洗阀座密封表面，有助于防止工业生产液流里的固体颗粒造成的破坏。
Clean the seating surfaces, helping to deter damage
caused from solids traveling in the process stream
- 通过引入清洗流体介质，可以在上游和下游阀座以外，在阀门内生成第三动态密封。
Create a third dynamic seal in the valve, in addition
to the upstream and downstream seats, by introducing the purge media
- 使用清洗流体介质产生一个安全保护层，因此消除了工业生产液流的泄漏通道。
Use the purge media to create a safety blanket,
thus eliminating escape paths for the process media
楔塞结构的其他内在优点是只有当阀门开启或关闭时才会消耗清洗流体介质。这就大大减少了整个清洗流体介质的损耗，以及相伴随的工业生产液流的损耗。
Another benefit inherent in the Wedgeplug design
is that the purge media is only consumed when the valve is being opened
or closed. This greatly reduces the overall consumption of purge media
and the subsequent removal from the process stream. |
Wedgetorque执行机构
Wedgetorque Operators
所有楔塞阀都配置Wedgetorque操作机构，以确保优化扭矩阀座，并提供下列特征和优点。
All Wedgeplug valves are supplied with Wedgetorque
operators to ensure optimum torque seating, providing the following features
and benefits.
- Wedgetorque操作机构提升无润滑阀塞，并旋转90o，然后再重新放置到阀座内，并将扭矩转换到操作螺丝上。
The Wedgetorque lifts the non-lubricated plug
and rotates it 90o, reseating it as torque is transmitted
to the operating screw.
- Wedgetorque操作机构通过机械推力提供积极的阀座密封，确保上游和下游阀座的紧密密封。
The Wedgetorque provides positive seating from
mechanical thrust, ensuring tight sealing of upstream and downstream
seats.
- 自动弥补磨损和加工温度波动造成的变化。
Automatic compensation for wear and process temperature
variations.
- 制造和库存的Wedgetorque操作机构具有几个系列的尺寸，能够满足全系列楔塞阀门的需要。
The Wedgetorque is manufactured and stocked in
several group sizes for a full range of Wedgeplug valves.
- 原先提供的楔塞阀配置的是螺纹类型的操作机构，能够方便的重新磨光整修，以配置新的轭架和Wedgetorque操作机构。
Originally supplied Wedgeplug valves with screw-type
operators, can be easily refurbished with new yokes and Wedgetorque
operators.

清洗和冲刷说明
Guidelines for Purging and Flushing
清洗和冲刷美国太平洋楔塞阀，采用蒸汽，空气，氮气或与生产工艺流体相兼容的流体，并符合下列参数，以增强阀门的性能。
Purge and flush Pacific Wedgeplug valves using
steam, air, nitrogen or process compatible liquids following these parameters
to enhance valve performance.
- 蒸汽清洗必须在比工艺管路压力高出最小25 PSIG，最大50 PSIG的压力范围内进行。
Steam purge must be applied at 25 PSIG min/50
PSIG max above process line pressure
- 空气或氮气清洗必须在比工艺管路压力高出最小25 PSIG，最大50 PSIG的压力范围内进行。
Air or nitrogen purge must be applied at 25 PSIG
min/50 PSIG max above process line pressure
- 液体清洗必须在比工艺管路压力高出最小5 PSIG，最大10 PSIG的压力范围内进行。
Liquid purge must be applied at 5 PSIG min/10
PSIG max above process line pressure
为了确保有点得到最好的发挥，在制定清洗和冲刷程序时，请遵循下列说明。
To ensure maximum benefit, follow the guidelines
below
when establishing purging and flushing procedures.
- 清洗介质应该与工艺流体介质相兼容。
Purge media should be compatible with process
media
- 系统温度和清洗温度应该相近。
Systems temperature and purge temperature should
be similar
- 在没有事先咨询美国太平洋楔塞阀门工厂之前，供应管路上应该没有限制(节流孔)。
Supply lines should have no restrictions (orifices)
without prior consultation of Pacific Wedgeplug
- 供应加热器应该能够提供适当的流量
Supply header should be sized for adequate volume
- 压力和温度表应该位于关键区域，以监视清洗流体介质
Pressure and temperature gauges should be placed
in critical areas to monitor purge media
- 蒸汽清洗管道应该尽可能的短，以防止冷凝物的累积
Steam purge lines should be as short as possible
to prevent condensate build-up
