貝爾戶外開關型固定式硬密封電動球閥

產品介紹

Q947H電(dian)動浮動球閥采用硬密封(feng)(feng)結構，設計有(you)(you)工(gong)作密封(feng)(feng)和檢修密封(feng)(feng)，操作力矩(ju)小(xiao)，密封(feng)(feng)比壓適(shi)中，密封(feng)(feng) 可靠(kao)，動作靈敏，液動控制易于實(shi)現自(zi)動控制，使用壽(shou)命長，球閥的壓力溫度額定值不僅(jin)與(yu)殼體材料有(you)(you)關，而且更多地(di)與(yu)閥座、填(tian)料及(ji)墊片等(deng)密封(feng)(feng)件材料有(you)(you)。廣(guang)泛使用于石油、化工(gong)、冶金、造(zao)紙(zhi)、制藥、電(dian)鍍等(deng)行業

二(er)、固定式電動硬密封(feng)球閥外形及(ji)結構

結構特點

1、流體阻力(li)小，球閥(fa)是所有閥(fa)類(lei)中流體阻力(li)zui小的一種，即使是縮(suo)徑球閥(fa)，其流體阻力(li)也相當(dang)小。

2、開關(guan)迅(xun)速、方便，只要閥桿(gan)轉動90°，球閥就完成了(le)全開或(huo)全關(guan)動作，很(hen)容易實現快速啟閉。

3、密(mi)封(feng)(feng)性能好。球(qiu)(qiu)閥(fa)閥(fa)座密(mi)封(feng)(feng)圈一般采用聚四氟乙烯等彈(dan)性材料(liao)制(zhi)造，易(yi)于保證密(mi)封(feng)(feng)，而且球(qiu)(qiu)閥(fa)的密(mi)封(feng)(feng)力隨著介質(zhi)壓力的增加而增大。

4、閥(fa)桿(gan)密(mi)(mi)封(feng)可靠。球(qiu)閥(fa)啟(qi)閉時閥(fa)桿(gan)只(zhi)作旋轉運動，因此閥(fa)桿(gan)的填(tian)料密(mi)(mi)封(feng)不易被破壞，而(er)且閥(fa)桿(gan)倒密(mi)(mi)封(feng)的密(mi)(mi)封(feng)力隨著(zhu)介(jie)質壓力的增加而(er)增大。

5、球閥(fa)的(de)啟閉只做(zuo)90°轉動，故容易實現(xian)自動化控(kong)制和遠距離控(kong)制，球閥(fa)可配(pei)置氣動裝置、電(dian)動裝置、液(ye)(ye)動裝置、氣液(ye)(ye)聯動裝置或(huo)電(dian)液(ye)(ye)聯動裝置。

6、球閥通道平(ping)整光滑，不易沉積介質，可以(yi)進行管線通球。

貝爾鄭重承(cheng)諾：產品出廠前均已經(jing)過各項嚴格品質(zhi)管制作(zuo)業及性能(neng)試驗，自即日(ri)起(qi)在正常使用狀況(kuang)下保固一年。但非人力所(suo)能(neng)抗拒之(zhi)災害，外力破壞(huai)，及未經(jing)本公司同意而(er)私自拆卸(xie)者不在保固范圍(wei)之(zhi)列。
