style="text-indent:25px">閥座的構(gòu)造類型很多，以往常見的有薄膜式、內(nèi)彈簧活塞式等。閥座的基本作用原理是靠閥座內(nèi)流道對(duì)水流的局部阻力降低水壓，水壓降的范圍由連接閥座瓣的薄膜或活塞兩側(cè)的進(jìn)出口水壓差自動(dòng)調(diào)節(jié)。近年來又出現(xiàn)一些新型閥座，如定比式閥座。定比減壓原理是利用閥座體中浮動(dòng)活塞的水壓比控制，進(jìn)出口端減壓比與進(jìn)出口側(cè)活塞面積比成反比。這種閥座工作平穩(wěn)無振動(dòng)；閥座體內(nèi)無彈簧，故無彈簧銹蝕、金屬疲勞失效之慮；密封性能良好不滲漏，因而既減動(dòng)壓又減靜壓；特別是在減壓的同時(shí)不影響水流量。閥座通常有DN50～DN100等多種規(guī)格，閥座前、后的工作壓力分別為＜1MPa和0．1～0．5MPa，調(diào)壓范圍誤差為±5％～10％。聚四氟乙烯閥座線膨脹系數(shù)為(10~15)乘以10-5/C,抗拉強(qiáng)度為10~30MPa。雙閥座球閥型號(hào)</p><p

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，延長了閥座的使用壽命。雙閥座球閥廠家直供</p><p
