訂購美國閥門的中英文對比
來源:  admin     日期  2011/5/12

  如何訂購美國閥門,美國閥門以質量過硬著稱,本文用中英文對比的方式更加直觀的教會你如何操作。
  
  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.
  
  在選擇最適合您的用途的閥門時應該小心謹慎。為了避免含糊不清,應該對每一個閥門做出精確的規定。在詢價或訂購時,應該對所需要的閥門做出全面、適當的說明。
  
  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.
  
  選擇閥門通徑
  
  Selecting the Valve Size
  
  必須確定與閥門連接的管道的公稱通徑。
  
  Nominal size of the pipeline into which the valve will be placed must be determined.
  
  閥門材料
  
  Valve Material
  
  在決定正確的閥門材料時,應該考慮下列因素:
  
  The following facts should be considered in determining the correct valve material:
  
  ·閥門所要控制的流體介質
  
  ·the medium or media which will be controlled
  
  ·流體介質的溫度范圍
  
  ·the temperature range of the line medium (media)
  
  ·閥門所要經受的壓力范圍
  
  ·the pressure range to which the valve will be subjected
  
  ·可能影響閥門工作的氣候條件
  
  ·possible atmospheric conditions which may affect the valve
  
  ·閥門所要經受的、可能的異常壓力或應力
  
  ·possible extraordinary stresses to which the valve will be subjected
  
  ·所要滿足的安全標準或管道規程
  
  ·safety standards and/or piping codes which must be met
  
  閥門類別
  
  Type of Valve
  
  閥門的控制功能是什么?每種閥門結構都是用于發揮某種功能。不要指望一種閥門能夠擔當整個管道系統內的所有功能。
  
  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.
  
  壓力-溫度額定值
  
  Pressure-Temperature Ratings
  
  為了滿足實際需要,請特別注意所需閥門的壓力-溫度額定值。要特別注意密封材料和襯墊材料,這些材料相當程度上決定了閥門的壓力-溫度額定值。根據實際需要指定密封材料和沉淀材料,以滿足或優于實際需求。
  
  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.

  閥門與連接方式
  
  Valve and Connections
  
  管道系統的完整性,未來的日常維護,防腐因素,現場裝配,重量和安全性等等因素都是決定了閥門與管道連接方式所應該考慮的因素。
  
  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.
  
  運行方式或操作方法
  
  Method of Operation
  
  根據閥門種類、大小、壓力、溫度、安裝環境等因素選擇適當的運行方式或操作方法。
  
  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.
  
  閥門的訂購
  
  rdering the Valve
  
  訂購閥門時,請提供下列數據,避免不必要的反復和延誤,確保所購買的閥門確實是自己所需要的閥門。
  
  Please state the following information when ordering a valve in order to avoid unnecessary delays and to insure we supply you with the valve you have requested.

  1.閥門通徑
  
  Valve size
  
  2.壓力界面材料:鑄件和部件材料。
  
  Pressure boundary material - metallurgy of the castings and components.
  
  3.閥門種類:閘閥,截止閥,止回閥,蝶閥,球閥,等等。
  
  Type of valve - gate, globe, check, etc.
  
  4.終端連接方式,如果連接方式為焊接方式,還要提供連接管道的管壁厚度;如果連接方式是法蘭,則要提供法蘭表面或拋光度。
  
  End connection including wall thickness of connecting pipe if weld end and any special flange facings or finishes
  
  5.任何與標準配置不同的材料:密封材料,沉淀材料,螺栓材料,等等。
  
  Any material deviations from standard - packing, gasket, bolting, etc.
  
  6.任何附件:防酸保護層,鎖定裝置,鏈條操作,等等。
  
  Any accessories - acid shield, locking devices, chain operation, etc.
  
  7.人工或動力執行機構:請包括所要求的技術細節。
  
  Manual or power actuators, please include details of requirements.
  
  8.為了訂購方便起見,請確定規格型號。
  
  For convenience in ordering, specify by figure number. Contact Aloyco for additional assistancein valve selection.
  
  我們希望能夠幫助您針對各種各樣的管道環境選擇正確的閥門。我們為您提供品種豐富的閥門供您選擇。這些閥門在本網戰中都有詳細的介紹。
