class="box"><p><p style="text-indent:25px">閥門安裝的一般規(guī)定：1.閥門安裝的位置不應(yīng)妨礙設(shè)備，管道及閥體本身的操作，拆裝和檢修，同時要考慮到組裝外形的美觀。2.水平管道上的閥門，閥桿朝上安裝，或傾斜一定角度安裝，不可手輪向下安裝。高空管道上的閥門、閥桿和手輪可水平安裝，用垂向低處的鏈條遠距離操縱閥的啟閉。3.排列對稱，整齊美觀；立管上的閥門，在工藝允許的前提下，閥門手輪以齊胸高較適宜操作，一般以距地面1.0—1.2m為宜，且閥桿必須順著操作者方向安裝。4.并排立管上的閥門，其中心線標高較好一致，且手輪之間凈距不小于100mm；并排水平管道上的閥門應(yīng)錯開安裝，以減小管道間距。5.在水泵、換熱器等設(shè)備上安裝較重的閥門時，應(yīng)設(shè)閥門支架；在操作頻繁且又安裝在距操作面1，青島閥門.8m以上的閥門時，應(yīng)設(shè)固定的操作平臺，青島閥門。6.閥門的閥體上有箭頭標志的，青島閥門，箭頭的指向即為介質(zhì)的流動方向。安裝閥門時，應(yīng)注意使箭頭指向與管道內(nèi)介質(zhì)流向相同。排氣閥是管道系統(tǒng)中必不可少的輔助元件。青島閥門</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="青島閥門,閥門" src="https://tyunfile.71360.com/UploadFile/lanfatonyon/637408829426729440/5460470.png"></div><p style="text-indent:25px">管道閥門的精髓：1.換向分流根據(jù)換向分流的需要，這種閥門可有三個或更多的通道。旋塞閥和球閥較適用于這一目的，因此，大部分用于換向分流的閥門都選取這類閥門中的一種。但是在有些情況下，其他類型的閥門，只要把兩個或更多個閥門適當?shù)叵嗷ミB接起來，也可作換向分流用。2.帶有懸浮顆粒的介質(zhì)當介質(zhì)中帶有懸浮顆粒時，較適于采用其關(guān)閉件沿密封面的滑動帶有擦拭作用的閥門。如果關(guān)閉件對閥座的來回運動是豎直的，那末就可能夾持顆粒，因此這種閥門除非密封面材料可以允許嵌入顆粒，否則只適用于基本清潔的介質(zhì)。球閥和旋塞閥在啟閉過程中對密封面均有擦拭作用，故適宜用在帶有懸浮顆粒的介質(zhì)中。廣東閥門訂購閥門注脂時，注意閥門在開關(guān)位的問題。球閥維護保養(yǎng)時一般都處于開位狀態(tài)，特殊情況下選擇關(guān)閉保養(yǎng)。</p><div

style="text-indent:25px">閥門的用途普遍，種類繁多，分類方法也比較多?？偟目煞謨纱箢悾嚎壳邦愖詣娱y門：依靠介質(zhì)(液體、氣體)本身的能力而自行動作的閥門。如止回閥、安全閥、調(diào)節(jié)閥、疏水閥、減壓閥等。第二類驅(qū)動閥門：借助手動、電動、液動、氣動來操縱動作的閥門。如閘閥，截止閥、節(jié)流閥、蝶閥、球閥、旋塞閥等。此外，閥門的分類還有以下幾種方法：一、按結(jié)構(gòu)特征，根據(jù)關(guān)閉件相對于閥座移動的方向可分：1. 截門形：關(guān)閉件沿著閥座中心移動。2. 閘門形：關(guān)閉件沿著垂直閥座中心移動。3. 旋塞和球形：關(guān)閉件是柱塞或球，圍繞本身的中心線旋轉(zhuǎn)。一般逆時針方向為開，順時針方向為關(guān)，但特定環(huán)境下也有相反的，具體看說明書。4. 旋啟形；關(guān)閉件圍繞閥座外的軸旋轉(zhuǎn)。5. 碟形：關(guān)閉件的圓盤，圍繞閥座內(nèi)的軸旋轉(zhuǎn)。6. 滑閥形：關(guān)閉件在垂直于通道的方向滑動。</p><p style="text-indent:25px">安裝閥門的注意事項：1.污水、雨水、冷凝水管不做閉水試驗便做隱蔽。后果：可能造成漏水，并造成用戶損失。措施：閉水試驗工作應(yīng)嚴格按規(guī)范檢查驗收。地下埋設(shè)、吊頂內(nèi)、管子間等暗裝污水、雨水、冷凝水管等要達到確保不滲不漏。2.管道系統(tǒng)水壓強度試驗和嚴密性試驗時，*觀察壓力值和水位變化，對滲漏檢查不夠。后果：管道系統(tǒng)運行后發(fā)生滲漏現(xiàn)象，影響正常使用。措施：管道系統(tǒng)依據(jù)設(shè)計要求和施工規(guī)范規(guī)定進行試驗時，除在規(guī)定時間內(nèi)記錄壓力值或水位變化，特別要仔細檢查是否存在滲漏問題。3.蝶閥法蘭盤用普通閥門法蘭盤。后果：蝶閥法蘭盤與普通閥門法蘭盤尺寸大小不一，有的法蘭內(nèi)徑小，而蝶閥的閥瓣大，造成打不開或硬性打開而使閥門損壞。措施：要按照蝶閥法蘭的實際尺寸加工法蘭盤。如果閥門使用環(huán)境較為惡劣，易受雨雪、灰塵、風沙等污物沾染，則應(yīng)該為閥桿安裝保護罩。</p><div

style="text-indent:25px">安全閥工作原理：安全閥在系統(tǒng)中起安全保護作用，安全閥的啟閉件受外力作用下處于常閉狀態(tài)，當設(shè)備或管道內(nèi)的介質(zhì)壓力升高超過規(guī)定值時，通過向系統(tǒng)外排放介質(zhì)來防止管道或設(shè)備內(nèi)介質(zhì)壓力超過規(guī)定數(shù)值。安全閥作用安全閥屬于自動閥類，主要用于鍋爐、壓力容器和管道上，控制壓力不超過規(guī)定值，對人身安全和設(shè)備運行起重要保護作用。注安全閥必須經(jīng)過壓力試驗才能使用。試壓方法：安全閥的強度試驗與其他閥門一樣，是用水作試驗的。試驗閥體下部時，壓力從進I=I端引入，密封面封閉；試驗閥體上部和閥蓋時，壓力從出El端引入，其他端封閉。在規(guī)定時間內(nèi)閥體和閥蓋無滲漏現(xiàn)象為合格。密封性試驗和定壓試驗，一般使用介質(zhì)是：蒸汽用安全閥以飽和蒸汽為試驗介質(zhì)；氨或其他氣體用閥以空氣為試驗介質(zhì)；水和其他非腐蝕性液體用閥以水為試驗介質(zhì)。對于一些重要位置的安全閥常用氮氣為試驗介質(zhì)。密封試驗以公稱壓力值為試驗壓力進行試驗，其次數(shù)不少于兩次，在規(guī)定時間內(nèi)無滲漏為合格。除去通口封蓋，檢查密封程度，閥瓣必須關(guān)閉嚴密。江西閥門批發(fā)</p><p style="text-indent:25px">閥門可以對這些變化進行連續(xù)或重復的操作。青島閥門</p><p style="text-indent:25px">減壓閥工作原理：減壓閥種類很多, 主要有活塞式和彈簧薄膜式兩種。活塞式減壓閥是通過活塞的作用進行減壓的閥門。彈簧薄膜式減壓閥, 是依靠彈簧和薄膜來進行壓力平衡的。減壓閥作用減壓閥是將介質(zhì)壓力降低到一定數(shù)值的自動閥門，一般閥后壓力要小于閥前壓力的50% 。試壓方法減壓閥的強度試驗一般以單件試驗后組裝，亦可組裝后試驗。強度試驗持續(xù)時間：DN<50mm的lmin；DN65～150mm的大于2min；DN>150mm的大于3min。波紋管與組件焊接后，應(yīng)用減壓閥后較高壓力的1．5倍、用空氣進行強度試驗。密封性試驗時按實際工作介質(zhì)進行。用空氣或水試驗時，以公稱壓力的1．1倍進行試驗；用蒸汽試驗時，以工作溫度下允許的較高工作壓力進行。進口壓力與出口壓力之差要求不小于0.2MPa。試驗方法為：進口壓力調(diào)定后，逐漸調(diào)節(jié)該閥的調(diào)節(jié)螺釘，使出口壓力在較大與較小值范圍內(nèi)能靈敏地、連續(xù)地變化，不得有停滯、卡阻現(xiàn)象。對蒸汽減壓閥，當進口壓力調(diào)走后，關(guān)閉閥后截斷閥，出口壓力為較高和較低值。青島閥門</p></p><br
