教大家怎樣來訂購?fù)鈬?guó)的閥門
本文用中英文對(duì)比的方式更加直觀的教會(huì)你如何操作。
　　我們希望能夠幫助您針對(duì)各種各樣的管道環(huán)境選擇正確的閥門。我們?yōu)槟�提供品種豐富的閥門供您選擇。這些閥門在本網(wǎng)戰(zhàn)中都有詳細(xì)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.
　　在選擇最適合您的用途的閥門時(shí)應(yīng)該小心謹(jǐn)慎。為了避免含糊不清，應(yīng)該對(duì)每一個(gè)閥門做出精確的規(guī)定。在詢價(jià)或訂購時(shí)，應(yīng)該對(duì)所需要的閥門做出全面、適當(dāng)?shù)恼f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(shí)，應(yīng)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(zhì)
　　·the medium or media which will be controlled
　　·流體介質(zhì)的溫度范圍
　　·the temperature range of the line medium (media)
　　·閥門所要經(jīng)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(jīng)受的、可能的異常壓力或應(yīng)力
　　·possible extraordinary stresses to which the valve will be subjected
　　·所要滿足的安全標(biāo)準(zhǔn)或管道規(guī)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(jié)構(gòu)都是用于發(fā)揮某種功能。不要指望一種閥門能夠擔(dān)當(dāng)整個(gè)管道系統(tǒng)內(nèi)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(shí)際需要，請(qǐng)?zhí)貏e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(dāng)程度上決定了閥門的壓力-溫度額定值。根據(jù)實(shí)際需要指定密封材料和沉淀材料，以滿足或優(yōu)于實(shí)際需求。
