教你如何訂購進口閥門
進口閥門以質量過硬著稱，如何訂購進口閥門，本文用中英文對比的方式更加直觀的教會你如何操作。
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。
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 de＆#115;cription 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.
