specified to meet unusual temperatures or corrosive conditions.
楔形塞阀门垫圈材料
Wedgeplug Valve Gasket Materials
压力等级为150和300的楔形塞阀门通常配置的垫圈是波纹状软铁，具有优异的强度和延展性。压力等级600 - 1500则采用环连接类型。
Gaskets regularly furnished in Class 150 and 300
Wedgeplug valves are corrugated soft iron of excellent strength and ductibility.
Classes 600 - 1500 are ring-joint type.
对于特殊的温度、压力和腐蚀性应用环境，可提供各种各样的垫圈供用户选择。如果有特殊要求，请与我们联系。
A variety of gasket materials may be furnished
for unusual temperatures, pressures, and corrosive conditions. For specific
recommendations, consult us.
楔形塞阀门的填料材料

in Materials of Construction.
安装
Installation
搬运处理 - 阀门应该安装在清洁的管线上。利用阀门上的凸耳进行搬运。如果没有凸耳，则应该采用吊索。绝对不能用手抡或阀杆来提起阀门。
Handling
- Valves should always be installed in clean lines. Use lifting lugs where
provided. If lugs are not provided, slings should be used. VALVES MUST
NEVER BE LIFTED BY HANDWHEELS OR STEMS.
阀门应该只能安装在水平流向的管线上，其阀杆应该垂直向上。如果需要其它方式的安装，请在订购阀门时咨询工厂。
Valves should be installed in the (stem) vertical
position with the pipe flow horizontal only. For installations other than
this, please consult factory when ordering.
润滑 - 在配置润滑油连接件的地方，应该对阀门进行定期润滑。
Lubrication
- Where lube fittings are provided, valves should be lubricated periodically.
楔形扭矩操作机构应该定期进行润滑。操作人员应该每年对这种阀门至少润滑一次。
Wedge torque operators should be lubed periodically.
As a minimum, the operators should be lubricated annually.

检测
Testing
所有美国太平洋楔形塞阀门在出厂之前，都经过一系列质量保证管理程序和检测程序。下面是对于所有阀门进行的标准检测程序的简单介绍，对于用户要求的备选检测程序和其它特殊检测程序，也相应进行简单介绍。
All Pacific Wedgeplug valves are subjected to
an extensive quality assurance and testing program prior to shipment.
Below is a brief description of standard testing performed on all valves
as well as optional tests and other special requirements which may be
performed at the customer’s request.
标准检测程序
Standard Testing
壳体检测—所有阀门都经过流体静力学壳体检测，根据ANSI B16.34和MSS SP-61的标准，最低检测压力为在37oC温度下，额定压力的1.5倍。
Shell Test—All
valves are hydrostatically shell tested at a minimum of 1.5 times the
100oF rated pressure for the pressure class in accordance with
ANSI B16.34 and MSS SP-61.
阀座压缩检测—所有阀门阀座都经过气压检测，根据API-598标准，最低检测气压为80 psig.
Seat Closure Test—All
valve seats are tested with air at a minimum of 80 psig in accordance
with API-598.
备选检测程序
Optional Testing
API检测—如果用户指定，阀门可以按照API-598标准进行检测。
API Testing—When specified, valves
can be tested in accordance with AP1-598.
其它特殊检测
Other Special Testing
