style="text-indent:25px">軟密封閥座結(jié)構(gòu)：（1）普通式：普通閥座的特點是在預(yù)緊力或流體壓力作用下閥座與球體壓緊，并使閥座材料產(chǎn)生彈塑性變形而達到密封，其密封效果取決于閥座在流體壓力或預(yù)緊力的作用下補償球體圓度和表面微觀不平度的能力。因此，閥座與球體之間必須具有足夠大的密封比壓。（2）彈性式：彈性閥座借助于彈性元件，如金屬彈簧架和彈簧等，在預(yù)緊力或流體壓力下產(chǎn)生彈性變形，以補償溫差、壓力和磨損等外界條件變化對球體密封性能的影響。（3）彈簧組合式：彈簧組合式閥座是沿閥門通道橫向截面圓周均布一組壓縮彈簧或*用一只碟型彈簧的推力，始終保持閥座壓緊球體而達到預(yù)緊狀態(tài)。福建閥桿閥座磨損修復(fù)聚三氟氯乙烯閥座線膨脹系數(shù)為(415~710)乘以10-5/°C,抗拉強度為35"40MPa。</p><div

style="text-indent:25px">焊接閥座往往分為三大步驟：1預(yù)熱，2焊接，3冷卻；控制好一個合適的溫度，焊接方法和相應(yīng)的電流參數(shù)，以及焊后的冷卻速度，才能得到一個高質(zhì)量的焊接效果；球閥閥座常用材料-特殊高分子材料高分子材料分通用高分子材料和特殊高分子材料兩大類。通用高分子材料主要有聚氯乙烯、聚乙烯、聚丙烯、環(huán)氧樹脂、酚醛樹脂和呋喃樹脂等。特殊高分子材料主要有聚四氯乙烯、聚三氟氯乙烯、聚全氟乙丙烯、聚醚醚酮和聚酰亞胺等。聚四氟乙烯：聚四氟乙烯(PTFE-F4)具有優(yōu)良的耐熱性和耐寒性，并具有不粘性、良好的自潤滑性和低摩擦系數(shù)(005)等特點，但是有冷流傾向。活塞式閥座是依靠進口介質(zhì)壓力產(chǎn)生密封力，閥座被推動壓緊球體，密封圈產(chǎn)生彈塑性變形實現(xiàn)密封。</p><div
