開關型普通鑄鋼法蘭電動球閥

產品介紹

Q947H電(dian)動(dong)浮動(dong)球閥采用(yong)(yong)(yong)硬密(mi)封結構，設計(ji)有(you)工(gong)作密(mi)封和檢修密(mi)封，操作力(li)矩小，密(mi)封比壓適中，密(mi)封 可靠，動(dong)作靈敏，液動(dong)控制(zhi)易于實現自動(dong)控制(zhi)，使用(yong)(yong)(yong)壽命長，球閥的壓力(li)溫度額定值不僅與殼體(ti)材料(liao)有(you)關，而且(qie)更(geng)多地與閥座、填(tian)料(liao)及墊片等(deng)密(mi)封件(jian)材料(liao)有(you)。廣(guang)泛使用(yong)(yong)(yong)于石油、化工(gong)、冶金、造紙、制(zhi)藥、電(dian)鍍等(deng)行(xing)業

二、固定式(shi)電動硬密封球閥(fa)外形及結構

結構特點

1、流(liu)體阻(zu)(zu)力小，球閥(fa)是(shi)所(suo)有閥(fa)類中(zhong)流(liu)體阻(zu)(zu)力zui小的一種，即使是(shi)縮徑球閥(fa)，其流(liu)體阻(zu)(zu)力也(ye)相(xiang)當小。

2、開關迅速(su)、方便，只要閥(fa)桿轉(zhuan)動(dong)90°，球閥(fa)就完成了全(quan)開或全(quan)關動(dong)作，很容易實現快(kuai)速(su)啟閉。

3、密封性能好。球(qiu)閥(fa)閥(fa)座密封圈(quan)一般采用聚(ju)四(si)氟乙烯(xi)等彈性材料制造(zao)，易于保證密封，而且球(qiu)閥(fa)的(de)密封力(li)隨著介質(zhi)壓力(li)的(de)增加而增大。

4、閥(fa)桿(gan)(gan)密封可靠。球閥(fa)啟閉時(shi)閥(fa)桿(gan)(gan)只作旋轉(zhuan)運動(dong)，因此閥(fa)桿(gan)(gan)的(de)填料密封不易被破壞，而(er)且(qie)閥(fa)桿(gan)(gan)倒密封的(de)密封力隨著介質壓力的(de)增(zeng)加而(er)增(zeng)大。

5、球(qiu)閥(fa)(fa)的啟閉只做90°轉動，故容易實現自動化(hua)控制和遠距離控制，球(qiu)閥(fa)(fa)可(ke)配置(zhi)氣動裝(zhuang)置(zhi)、電動裝(zhuang)置(zhi)、液動裝(zhuang)置(zhi)、氣液聯動裝(zhuang)置(zhi)或電液聯動裝(zhuang)置(zhi)。

6、球閥通道平整光滑，不易沉(chen)積介(jie)質，可以進(jin)行(xing)管(guan)線通球。

貝爾鄭重(zhong)承諾(nuo)：產品出(chu)廠前均已(yi)經過各項嚴(yan)格品質管制作業(ye)及(ji)性能試驗，自(zi)即日起在正常(chang)使用狀況下保(bao)(bao)固一年(nian)。但非人力(li)所能抗拒之災害，外(wai)力(li)破(po)壞(huai)，及(ji)未(wei)經本公司同意而私自(zi)拆(chai)卸者不在保(bao)(bao)固范圍之列。
