普通開關型固定式大口徑電動鑄鋼球閥

產品介紹

Q947H電(dian)動(dong)(dong)浮(fu)動(dong)(dong)球(qiu)(qiu)閥(fa)(fa)采用硬(ying)密封(feng)(feng)結構，設計有(you)工作(zuo)密封(feng)(feng)和檢修密封(feng)(feng)，操作(zuo)力矩(ju)小，密封(feng)(feng)比壓適中，密封(feng)(feng) 可靠，動(dong)(dong)作(zuo)靈敏，液(ye)動(dong)(dong)控制(zhi)易于(yu)實現自動(dong)(dong)控制(zhi)，使(shi)用壽(shou)命長，球(qiu)(qiu)閥(fa)(fa)的(de)壓力溫度(du)額定值(zhi)不(bu)僅與殼體(ti)材(cai)料(liao)有(you)關，而且更多地與閥(fa)(fa)座、填料(liao)及墊片等密封(feng)(feng)件材(cai)料(liao)有(you)。廣泛使(shi)用于(yu)石油、化工、冶金、造紙(zhi)、制(zhi)藥(yao)、電(dian)鍍(du)等行業

二(er)、固定式電動(dong)硬密(mi)封球閥外(wai)形及結構

結構特點

1、流體(ti)阻力小(xiao)，球(qiu)閥是所有閥類(lei)中流體(ti)阻力zui小(xiao)的一種，即使(shi)是縮徑(jing)球(qiu)閥，其流體(ti)阻力也相當小(xiao)。

2、開關迅速、方便，只要(yao)閥桿轉動90°，球閥就(jiu)完成了全開或全關動作，很容易實現快速啟閉。

3、密(mi)封性能好。球閥(fa)閥(fa)座(zuo)密(mi)封圈一般(ban)采用聚四氟乙烯等彈性材料(liao)制造，易于保證密(mi)封，而且球閥(fa)的密(mi)封力隨著介質(zhi)壓力的增加而增大(da)。

4、閥桿密(mi)封(feng)可靠。球(qiu)閥啟閉時閥桿只作旋(xuan)轉(zhuan)運(yun)動，因此閥桿的填料密(mi)封(feng)不易被(bei)破壞，而且閥桿倒密(mi)封(feng)的密(mi)封(feng)力隨著(zhu)介(jie)質壓力的增加而增大。

5、球(qiu)閥(fa)的啟閉只做90°轉動(dong)(dong)(dong)(dong)，故(gu)容易(yi)實現(xian)自(zi)動(dong)(dong)(dong)(dong)化控制和遠距離控制，球(qiu)閥(fa)可配置氣動(dong)(dong)(dong)(dong)裝(zhuang)置、電動(dong)(dong)(dong)(dong)裝(zhuang)置、液(ye)動(dong)(dong)(dong)(dong)裝(zhuang)置、氣液(ye)聯動(dong)(dong)(dong)(dong)裝(zhuang)置或電液(ye)聯動(dong)(dong)(dong)(dong)裝(zhuang)置。

6、球閥通(tong)(tong)道平整光滑，不易沉積介(jie)質，可(ke)以(yi)進行管線通(tong)(tong)球。

貝(bei)爾鄭重承諾：產品(pin)出(chu)廠(chang)前均(jun)已經(jing)過各(ge)項嚴格品(pin)質(zhi)管制作業及(ji)性(xing)能(neng)試(shi)驗，自(zi)即日起在(zai)正常使用狀況下保(bao)固一(yi)年。但(dan)非人力所能(neng)抗拒之災害，外力破壞，及(ji)未經(jing)本公司同意(yi)而私(si)自(zi)拆(chai)卸者不在(zai)保(bao)固范圍之列。
