產品介紹

Q947H電(dian)動(dong)浮動(dong)球閥采用硬(ying)密(mi)(mi)封(feng)結(jie)構，設計有工作密(mi)(mi)封(feng)和檢修(xiu)密(mi)(mi)封(feng)，操作力矩(ju)小(xiao)，密(mi)(mi)封(feng)比壓(ya)適(shi)中，密(mi)(mi)封(feng) 可靠，動(dong)作靈敏，液(ye)動(dong)控(kong)制易于實(shi)現自動(dong)控(kong)制，使用壽命長，球閥的壓(ya)力溫(wen)度額定值不僅(jin)與(yu)殼體材料(liao)有關，而且更多地與(yu)閥座、填料(liao)及墊片等(deng)密(mi)(mi)封(feng)件材料(liao)有。廣泛使用于石油(you)、化(hua)工、冶(ye)金、造紙、制藥、電(dian)鍍等(deng)行業

二(er)、固定式電動硬(ying)密封球閥外形及結構(gou)

結構特點

1、流體阻(zu)力小，球閥(fa)(fa)是所有閥(fa)(fa)類中(zhong)流體阻(zu)力zui小的一種，即(ji)使是縮徑球閥(fa)(fa)，其流體阻(zu)力也相當小。

2、開關(guan)迅(xun)速(su)、方便，只要閥桿轉(zhuan)動90°，球(qiu)閥就完成(cheng)了全開或(huo)全關(guan)動作，很(hen)容易實現快速(su)啟閉。

3、密封性能(neng)好。球(qiu)(qiu)閥閥座密封圈(quan)一(yi)般采用聚四氟乙(yi)烯等彈(dan)性材料制造，易于保(bao)證密封，而(er)且球(qiu)(qiu)閥的密封力隨著介(jie)質壓力的增加而(er)增大(da)。

4、閥(fa)桿(gan)密封可靠。球閥(fa)啟閉時閥(fa)桿(gan)只(zhi)作旋轉運動(dong)，因(yin)此閥(fa)桿(gan)的(de)填料密封不(bu)易被破壞(huai)，而且(qie)閥(fa)桿(gan)倒密封的(de)密封力(li)隨著介質壓(ya)力(li)的(de)增加而增大。

5、球(qiu)閥(fa)(fa)的(de)啟閉只做90°轉動(dong)(dong)，故容易實現自動(dong)(dong)化控制和遠(yuan)距(ju)離控制，球(qiu)閥(fa)(fa)可配(pei)置(zhi)氣動(dong)(dong)裝(zhuang)置(zhi)、電動(dong)(dong)裝(zhuang)置(zhi)、液(ye)動(dong)(dong)裝(zhuang)置(zhi)、氣液(ye)聯動(dong)(dong)裝(zhuang)置(zhi)或電液(ye)聯動(dong)(dong)裝(zhuang)置(zhi)。

6、球閥通道平整光滑，不(bu)易沉積介(jie)質，可以進(jin)行管線通球。

貝爾鄭重承(cheng)諾：產品出廠前均(jun)已經過(guo)各項嚴格品質(zhi)管制作業及(ji)性能試驗，自即日起在正常使用狀況下保固一(yi)年。但非(fei)人力所能抗拒之災(zai)害，外力破壞，及(ji)未經本公司同意(yi)而私自拆卸者不在保固范圍之列(lie)。
