宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 空調(diào)器主要由</span><span style="color:#353535;font-family:'Microsoft Yahei, Tahoma, SimSun, 宋體';font-size:small;"><span style="outline-color:initial;cursor:pointer;background-color:#FFFFFF;transition-duration:0.3s;transition-property:all;">制冷</span></span><span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;">系統(tǒng)、風道系統(tǒng)、結(jié)構(gòu)系統(tǒng)、電氣系統(tǒng)組成。閥類作為制冷系統(tǒng)的重要組成部分，其零部件的質(zhì)量好壞將直接導致產(chǎn)品質(zhì)量好壞。為此，我們需要從設(shè)計、制造、檢驗的每一個環(huán)都應(yīng)該嚴格控制其質(zhì)量。今天和大家介紹下制冷系統(tǒng)高、低壓閥(截止閥)的作用、工作原理和故障問題分析。</span> <div style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;text-align:center;"> </div> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> (一)作用：截止閥在制冷系統(tǒng)管路中起開斷作用，就是在室內(nèi)、室外機聯(lián)機前將</span><span style="color:#353535;font-family:'Microsoft Yahei, Tahoma, SimSun, 宋體';font-size:small;"><span style="outline-color:initial;cursor:pointer;background-color:#FFFFFF;transition-duration:0.3s;transition-property:all;">制冷劑</span></span><span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;">密封在冷凝器中。開啟的大小可控制制冷劑流量的多少和流動的方向，設(shè)備之間的接通、切斷全由截止閥完成。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> (二)閥體結(jié)構(gòu)：截止閥分為低壓閥和高壓閥。還可以根據(jù)密封圈的數(shù)量分為單O和雙O閥。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 1、截止閥主要由閥芯、閥體、氣門芯(低壓閥)、螺母、連接配管組成。由密封圈、黃銅棒等組成閥芯的升降控制開啟的程度;當閥芯旋到閥體底部時與閥體底部的錐面緊密配合起到封閉作用。圖中的密封圈是防冷媒泄漏用的。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 2、高壓閥與低壓閥的區(qū)別：低壓閥有充注口，內(nèi)有氣門芯。主要用來市場維修時充注雪種。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> (三)截止閥的加工工藝：</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 1、材料選擇：閥體材料應(yīng)使用Hpb59-1擠壓棒、軋制棒或冷拔棒，去應(yīng)力退火處理。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 2、加工方式：數(shù)控加工中心，特點是一次裝夾(整體一次性完成)和操作時間短，10~14秒鐘的時間內(nèi)的操作就可以完成一件閥體件的生產(chǎn)，減少了二次裝夾帶來的行位公差不一致的缺陷，而且加工精度及一致性均比后者好。尤其是閥芯必須采用數(shù)控加工中心方式加工，才能保證z*大限度的消除閥芯形位公差尺寸誤差，保證閥芯的可靠性和質(zhì)量。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 3、銅棒加熱(鍛造閥體毛坯的前工序)：采用中頻感應(yīng)爐加熱技術(shù)，自動程度較好，溫度控制精度能達±40℃范圍，而且鍛造時間也能有效控制，這與未采用此技術(shù)的截止閥的廠家(靠火焰加熱+鍛壓的工序來實現(xiàn))是有很大區(qū)別的。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 4、閥體表面噴丸強化處理，目的在于部分除去加工殘留內(nèi)應(yīng)力。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 5、閥體對閥芯的固定方式：有三種，分別為縮口+卡環(huán)、卡環(huán)、縮口。單O閥芯固定方式推薦使用縮口+卡環(huán)，但必需使用卡環(huán)的固定形式，不允許只采用只縮口的形式進固定，雙O閥芯固定方式可以采用縮口的形式。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 6、截止閥閥口通徑和開度的設(shè)計：通徑的大小與開度有直接的關(guān)系，且是關(guān)鍵參數(shù)。開啟的大小可控制制冷劑流量的多少。美的目前的企業(yè)標準要求是：截止閥開啟高度應(yīng)大于1/2通徑。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 7、對閥內(nèi)表面與閥芯(有“O”型圈部分)配合的部分采取去毛刺滾光工藝，充分保證閥的密封性能(包括可靠性)和使用壽命。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> (四)關(guān)鍵質(zhì)量控制點：</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 對截止閥而言，其關(guān)鍵質(zhì)量控制點主要在于防止泄露。因而在檢驗過程中主要控制氣密性、充氟試驗，包括閥芯和氣門芯。還需要監(jiān)控其使用壽命，包括開關(guān)壽命試驗、閥體材料成分及加工殘留內(nèi)應(yīng)力、耐熱耐寒能力及密封圈和氣門芯的耐氟耐油能力。另外作為截止閥與室內(nèi)外連接管結(jié)合部位的錐面也是關(guān)鍵控制點，要求錐面不允許有凹痕、劃傷、污物、碰撞及徑向刀紋等影響密封的現(xiàn)象。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> (五)常見質(zhì)量問題分析</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 1、截止閥閥體開裂：對于閥體開裂問題，主要來說有以下幾個方面原因。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> A、原材料的選用：美的指定原材料牌號為：Hpb59-1擠壓棒、軋制棒或冷拔棒。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> B、對原材料毛坯的加工控制：加工鍛造的坯料，在加熱時，目前生產(chǎn)廠家有兩種方式加熱，一是火焰直接噴燒，這種加工方法對坯料的溫度控制波動很大，組織結(jié)構(gòu)均勻一致性較難保證。而用中頻電感應(yīng)加熱，材料溫度均勻性較好，但必須要求廠家嚴格執(zhí)行坯料到達加熱溫度后在空氣中停頓的時間間隔，以保證閥體的晶相結(jié)構(gòu)穩(wěn)定。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> C、加工殘留內(nèi)應(yīng)力：去應(yīng)力退火處理。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> 2、密封不嚴</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> A、錐面光潔度不好或不90角與連接管無閥密閉配合造成的漏。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> B、閥體本身漏，這主要是材料有裂紋，焊接不好引起的。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> C、閥芯與閥體的配合體不好引起的漏。與在“O”型密封圈表面、閥芯螺紋部分以及槽部涂的潤滑油類型也有很大關(guān)系。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> D、閥芯的密封圈老化及開裂引起的漏。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> E、閥體縮口不到位或沒有縮，系統(tǒng)的壓力將閥芯沖出引起的漏。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;" /> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun, 宋體;font-size:medium;white-space:normal;background-color:#FFFFFF;"> F、高壓閥的氣門芯密封不好引起的漏。在上緊氣門芯時，必須規(guī)定廠家的上緊力矩(專用力矩扳手)，因為上緊力的大小對密封性影響很大。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun,

G、因扭矩力太大引起的閥芯內(nèi)六角磨損使閥芯打不開或關(guān)不緊等現(xiàn)象。</span><br style="margin:0px;outline:none 0px;padding:0px;font-family:"Microsoft Yahei", Tahoma, SimSun,

3、焊接四通閥體、高(低)壓閥體時，若焊口離四通閥體、高(低)壓閥體比較近(≤150mm)時，需將四通閥體、高(低)壓閥體浸入水中或用濕毛巾浸水包住四通閥體、高(低)壓閥體后再焊接，以避免四通閥體、高(低)壓閥體內(nèi)密封圈受溫損壞。</span> </p> <p> <span style="font-family:"Microsoft Yahei", Tahoma, SimSun,
