style="text-indent:25px">閥座有哪些優(yōu)點(diǎn)？1、啟閉方便迅速、省力、流體阻力小，可以經(jīng)常操作。2、結(jié)構(gòu)簡(jiǎn)單，外形尺寸小，結(jié)構(gòu)長(zhǎng)度短，體積小，重量輕，適用于大口徑的閥座。3、可以運(yùn)送泥漿，在管道口積存液體少。4、低壓下，可以實(shí)現(xiàn)良好的密封。5、調(diào)節(jié)性能好。6、全開(kāi)時(shí)閥座通道有效流通面積較大，流體阻力較小。7、啟閉力矩較小，由于轉(zhuǎn)軸兩側(cè)閥板受介質(zhì)作用基本相等，而產(chǎn)生轉(zhuǎn)矩的方向相反，因而啟閉較省力。8、密封面材料一般采用橡膠、塑料、故低壓密封性能好。9、安裝方便。10、操作靈活省力，可選擇手動(dòng)、電動(dòng)、氣動(dòng)、液壓方式。閥座是閥門(mén)內(nèi)可拆卸面部件。南京氣動(dòng)球閥閥座</p><p
