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(gè)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(gè)或更多個(gè)閥門適當(dāng)?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(dāng)介質(zhì)中帶有懸浮顆粒時(shí)，較適于采用其關(guān)閉件沿密封面的滑動(dòng)帶有擦拭作用的閥門。如果關(guān)閉件對(duì)閥座的來回運(yùn)動(dòng)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(duì)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。無(wú)錫閥門電裝批發(fā)廠家如果閥門使用環(huán)境較為惡劣，易受雨雪、灰塵、風(fēng)沙等污物沾染，則應(yīng)該為閥桿安裝保護(hù)罩。</p><div

style="text-indent:25px">幾種常用管道閥門的安裝：一.閘閥又稱閘板閥，是利用閘板來控制啟閉的閥門，通過改變橫斷面來調(diào)節(jié)管路流量和啟閉管路。閘閥多用于對(duì)流體介質(zhì)做全啟或全閉操作的管路。閘閥安裝一般無(wú)方向性要求，但不能倒裝。二.截止閥是利用閥瓣來控制啟閉的閥門。通過改變閥瓣與閥座的間隙，即改變通道截面的大小來調(diào)節(jié)介質(zhì)流量或截?cái)嘟橘|(zhì)通路。安裝截止閥必須注意流體的流向。安裝截止閥必須遵守的原則是，管道中的流體由下而上通過閥孔，俗稱“低進(jìn)高出”，不許裝反。</p><p style="text-indent:25px">閥門注脂時(shí)的維護(hù)保養(yǎng)工作：閥門注脂時(shí)，常忽略壓力問題。在注脂操作時(shí)，注脂壓力有規(guī)律地呈峰谷變化。壓力過低，密封漏或失效，壓力過高，注脂口堵塞、密封內(nèi)脂類硬化或密封圈與閥球、閥板抱死。通常注脂壓力過低時(shí)，注入的潤(rùn)滑脂多流入閥腔底部，一般發(fā)生在小型閘閥。而注脂壓力過高，一方面檢查注脂嘴，如是脂孔阻塞判明情況進(jìn)行更換；另一方面是脂類硬化，要使用清洗液，反復(fù)軟化失效的密封脂，并注入新的潤(rùn)滑脂置換。此外，密封型號(hào)和密封材質(zhì)，也影響注脂壓力，不同的密封形式有不同的注脂壓力，一般情況硬密封注脂壓力要高于軟密封。閥門可以對(duì)這些變化進(jìn)行連續(xù)或重復(fù)的操作。</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(hù)作用，安全閥的啟閉件受外力作用下處于常閉狀態(tài)，當(dāng)設(shè)備或管道內(nèi)的介質(zhì)壓力升高超過規(guī)定值時(shí)，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(dòng)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(duì)人身安全和設(shè)備運(yùn)行起重要保護(hù)作用。注安全閥必須經(jīng)過壓力試驗(yàn)才能使用。試壓方法：安全閥的強(qiáng)度試驗(yàn)與其他閥門一樣，是用水作試驗(yàn)的。試驗(yàn)閥體下部時(shí)，壓力從進(jìn)I=I端引入，密封面封閉；試驗(yàn)閥體上部和閥蓋時(shí)，壓力從出El端引入，其他端封閉。在規(guī)定時(shí)間內(nèi)閥體和閥蓋無(wú)滲漏現(xiàn)象為合格。密封性試驗(yàn)和定壓試驗(yàn)，一般使用介質(zhì)是：蒸汽用安全閥以飽和蒸汽為試驗(yàn)介質(zhì)；氨或其他氣體用閥以空氣為試驗(yàn)介質(zhì)；水和其他非腐蝕性液體用閥以水為試驗(yàn)介質(zhì)。對(duì)于一些重要位置的安全閥常用氮?dú)鉃樵囼?yàn)介質(zhì)。密封試驗(yàn)以公稱壓力值為試驗(yàn)壓力進(jìn)行試驗(yàn)，其次數(shù)不少于兩次，在規(guī)定時(shí)間內(nèi)無(wú)滲漏為合格。如果閘板長(zhǎng)時(shí)期處于半開關(guān)的狀態(tài)下工作，閘板的密封面會(huì)因受介質(zhì)沖刷而變得不嚴(yán)密。無(wú)錫閥門電裝批發(fā)廠家</p><p
