style="text-indent:25px">閥座在使用時(shí)的注意事項(xiàng)：薄膜式閥座，適用于低壓、中壓、中小口徑的蒸汽或水等介質(zhì)；閥座進(jìn)口壓力的波動(dòng)應(yīng)控制在進(jìn)口壓力給定值的80%～105%，如超過該范圍，減壓前期的性能會(huì)受影響；通常閥座的閥座后壓力應(yīng)小于閥座前壓力的0.5倍；閥座的每一檔彈簧只在一定的出口壓力范圍內(nèi)適用，超出范圍應(yīng)更換彈簧；在介質(zhì)工作溫度比較高的場(chǎng)合，一般選用先導(dǎo)活塞式閥座或先導(dǎo)波紋管式閥座；介質(zhì)為空氣或水（液體）的場(chǎng)合，一般宜選用直接作用薄膜式閥座或先導(dǎo)薄膜式閥座；介質(zhì)為蒸汽的場(chǎng)合，宜選用先導(dǎo)活塞式或先導(dǎo)波紋管式閥座；為了操作、調(diào)整和維修的方便，閥座一般應(yīng)安裝在水平管道上。聚三氟氯乙烯閥座線膨脹系數(shù)為(415~710)乘以10-5/°C,抗拉強(qiáng)度為35"40MPa。福州電磁閥座維修</p><p
