style="text-indent:25px">閥芯在閥體內(nèi)需要運動，因此間隙的大小即要保證良好的密封性，又要保證較小的運動阻力。在實際生產(chǎn)中，一般采用配合副的零件互相研配的方法來保證較小的配合間隙。但是在成批和大量生產(chǎn)時，需要閥芯可以互換，這時配合間隙將適當(dāng)放大一些，這就可能引起泄漏量的出現(xiàn)。閥心水**的內(nèi)置閥心大多采用鋼球閥和陶瓷閥。鋼球閥具備堅實耐用的鋼球體、頑強的抗耐壓能力，但缺點是起密封作用的橡膠圈易損耗，很快會老化。陶瓷閥本身就具有良好的密封性能，而且采用陶瓷閥心的**，從手感上說更舒適、順滑，能達到很高的耐開啟次數(shù)，且開啟、關(guān)閉迅速，解決了跑、冒、滴、漏問題。</p><p
