如何指定和订购正确的阀门
How to Specify and Order the Correct Valves

  这本颁布的样本帮助您为各种管道应用领域选择正确的阀门。Aloyco(阿罗伊科)阀门系列为您提供一个广泛的选择。本样本对这些阀门进行了介绍。
  This catalog has been published to assist you in choosing the correct valve for a vast number of piping conditions. The Aloyco product line makes available to you a very broad choice of valves. These valves are described in this catalog.
  在为您的应用选择最适当的阀门时需要小心谨慎。必须明确每个阀门的规格说明,避免含糊不清。在寻求报价或订购时,必须对产品进行充分恰当的说明描述。
  Care should be taken to select the most suitable valves for your service(s). Exact specification of each valve should be made to avoid possible ambiguity. When requesting quotations and/or ordering the product a fully adequate description should be made.

确定阀门的通径
Selecting the Valve Size

  必须确定阀门将要安装进去的管道的公称通径。
  Nominal size of the pipeline into which the valve will be placed must be determined.

阀门材料
Valve Material

  在确定正确的阀门材料时,需要考虑下列因素:
  The following facts should be considered in determining the correct valve material:

  • 将要流经的流体介质
    the medium or media which will be controlled
  • 管道流体介质的温度范围
    the temperature range of the line medium (media)
  • 相关阀门的压力范围
    the pressure range to which the valve will be subjected
  • 可能影响阀门的气候条件
    possible atmospheric conditions which may affect the valve
  • 相关阀门的可能出现的异常应力
    possible extraordinary stresses to which the valve will be subjected
  • 所要符合的安全标准和/或管道规程
    safety standards and/or piping codes which must be met

阀门类型
Type of Valve

  阀门的控制功能是什么?各种结构的阀门具有某种控制功能。不要期望一种类型的阀门能够在系统中实现所有的阀门功能。
  What is the control function of the valve? Each valve configuration has been developed to perform certain control functions. Do not expect one type of valve to perform all the valving jobs in a system.

压力 - 温度等级
Pressure-Temperature Ratings

  请小心注意某个特定阀门的压力-温度等级是否满足应用的要求。请特别小心注意可能影响压力-温度等级的填料和垫圈材料,作为Aloyco(阿罗伊科)阀门的标准配置,这些材料是聚四氟乙烯材料。为了满足或优于您的应用要求,如果必要的话,请指定其它备选的填料和/或垫圈材料。
  Please pay careful attention that the pressure-temperature ratings of a particular valve are in keeping with the requirements of the service. Pay especially careful attention to the packing and gasket materials as this may limit the rating as is the case with PTFE used as the standard in Aloyco valves. Specify alternative packing and/or gasket materials as necessary to meet or exceed your service requirements.

 

阀门和连接
Valve and Connections

  在确定管线中阀门的连接方法时,需要考虑到管道的整体性,今后的维护,腐蚀性,现场安装,重量和安全等因素。
  Considerations as to pipeline integrity, future maintenance, corrosion factors, field assembly, weight and safety should be given in determining the method of connecting the valve in the pipeline.

操作方法
Method of Operation

  所供应的阀门的操作方法在本样本中有描述。许多其它操作装置通常由Aloyco(阿罗伊科)提供。
  The means by which the valve is operated as supplied are shown for the valves in this catalog. Many optional operating devices are regularly supplied by Aloyco.
