style="text-indent:25px">硬密封閥座結(jié)構(gòu)：（1）本體堆焊式：本體堆焊式閥座是在某種金屬材料上堆焊硬質(zhì)合金，閥座帶有一個(gè)彈性尾座，有利于減少密封面的摩擦損傷。（2）多層式：多層式密封閥座是多層不銹鋼片和多層薄石墨片交替疊放經(jīng)特殊的加工手段卷壓制而成的，提高了高溫高壓下的性能。（3）空心管式：空心管式密封閥座內(nèi)外是襯套，中間是不銹鋼管，靠空心的彈力使閥座壓緊球體。（4）旋轉(zhuǎn)式：旋轉(zhuǎn)密封閥座主要特點(diǎn)是閥門在啟閉過(guò)程中，閥座可沿通道軸線作旋轉(zhuǎn)運(yùn)動(dòng)，其結(jié)構(gòu)在閥座的圓周上分布一圈齒牙，球體每關(guān)閉一次，閥座旋轉(zhuǎn)一個(gè)齒。這樣使閥座沿圓周產(chǎn)生均勻磨損，從而改善了閥座工作狀況，延長(zhǎng)了閥座的使用壽命。天津沖水閥閥座大修</p><p
