style="font-size:16px;">球閥是由閥桿帶動作為啟閉件的球體，繞球閥軸線作旋轉(zhuǎn)運(yùn)動的閥門，可以用于流體的調(diào)節(jié)和控制。球閥問世于20世紀(jì)50年代，現(xiàn)在已經(jīng)成為應(yīng)用為的一大閥類。它的啟閉件是位于閥門中心處的球體，由閥桿帶動旋轉(zhuǎn)實(shí)現(xiàn)開閉操作。球閥和蝶閥，會寧球閥在哪里、旋塞閥一樣都是四分之一轉(zhuǎn)閥，可以快速啟閉，只需要轉(zhuǎn)動90°就可以從全開到全關(guān)。球閥的球體和閥體都由金屬材料制成，如不銹鋼；閥座是較為柔軟的彈性材料，如聚四氟乙烯、氯丁橡膠等，會寧球閥在哪里。這樣球體可以被壓在閥座上，使閥門得到良好的密封。球閥頂部與閥桿的連接處通常是矩形的，這可以讓我們在不造成球體變形的情況下施加較大的力矩，對閥門的開閉進(jìn)行控制。球閥的一大優(yōu)點(diǎn)是閥門全開時通過閥門的流體壓降很小，幾乎不受阻礙。球閥可以分為文丘里閥、縮徑球閥</span><span style="font-size:16px;">和全通徑球閥三種，其中全通徑球閥的流道尺寸與管道內(nèi)徑相同，會寧球閥在哪里，通過閥門的流體壓降非常小。</span> 快速啟閉閥門時，操作無沖擊;會寧球閥在哪里</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="font-size:16px;">球閥的主要功能是切斷或接通管道中的流體通道。球閥的工作原理是借助驅(qū)動裝置在閥桿上端施加一定的轉(zhuǎn)矩傳給球體，使其旋轉(zhuǎn)90°，完成開啟或關(guān)閉閥門的動作。球閥閥座的密封原理依其結(jié)構(gòu)而異，常用的閥座結(jié)構(gòu)可分為固定閥座浮動球體與浮動閥座固定球體兩大類。當(dāng)閥座固定球體浮動時，在流體壓力作用下球體在流體流動方向產(chǎn)生位移，使它與閥后閥座密封而更緊密地接觸，即在該密封面上的比壓增大，形成單面密封，同時，閥前閥座密封面上的比壓相應(yīng)減小，往往不保證密封。當(dāng)閥座浮動球體固定時，流體壓力不能使球體產(chǎn)生位移，而是閥座借助于彈簧或流體推力壓向球體，建立密封比壓。普通閥座的特點(diǎn)是在預(yù)緊力或流體壓力作用下閥座與球體壓緊，并使閥座材料產(chǎn)生彈塑性變形而達(dá)到密封，其密封效果取決于閥座在流體壓力或預(yù)緊力的作用下補(bǔ)償球體圓度和表面微觀不平度的能力。因此，閥座與球體之間必須具有足夠大的密封比壓。</span>
