style="text-indent:25px">閥門銅配件密封閥座的結(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銅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，中間是銅管，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。</p><p style="text-indent:25px">閥門銅配件閥座處于徹底開啟方位時(shí)，閥板厚度是介質(zhì)流經(jīng)閥座體時(shí)的阻力，因而通過(guò)該閥座所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。閥座有彈密封和金屬的密封兩種密封型式。彈性密封閥座，密封圈可以鑲嵌在閥座體上或附在閥板周邊。采用金屬密封的閥座一般比彈性密封的閥座壽命長(zhǎng)，但很難做到徹底密封。金屬密封能習(xí)慣較高的工作溫度，彈性密封則具有受溫度限制的缺點(diǎn)。如果要求閥座作為流量控制運(yùn)用，主要的是正確選擇閥座的尺度和類型。閥座的結(jié)構(gòu)原理特別適合制作大口徑閥座。閥座不只在石油、煤氣、化工、水處理等一般工業(yè)上得到普遍應(yīng)用，并且還應(yīng)用于熱電站的冷卻水系統(tǒng)。閥門銅配件閥座需借助于彈性元件。</p><div
