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)無滲漏為合格。宜興礦用隔爆型閥門銷售廠家</p></p><br
