全通徑雙偏心半球閥說(shuō)明:
BQ347型為蝸輪傳動(dòng),兩端法蘭連接全通徑雙偏心式半球閥?蓮V泛用于市政、冶金、燃?xì)、石油化工、電力行業(yè)的管線閥遠(yuǎn)距離輸送要求。具有下列優(yōu)點(diǎn):
1、 全通徑屬于直通式,閥體通道與管線連接的管道成直管相通,截面積相等,中間無(wú)任何阻礙的地方,所以該閥稱為大流量直通閥。選用不同的材質(zhì)可以達(dá)到各行業(yè)的要求;
2、 操作簡(jiǎn)便,啟閉迅速全開(kāi)、只要旋轉(zhuǎn)90°即可達(dá)到方便于遠(yuǎn)離控制,長(zhǎng)距離管線輸送,易于實(shí)現(xiàn)事故的緊急處理;
3、 適用于含雜質(zhì),有結(jié)晶析出或含有沉淀的介質(zhì),不像
截止閥、
閘閥那樣,它不存在存有介質(zhì)的死角,不會(huì)發(fā)生密封泄漏故障;
4、 密封面開(kāi)啟后,閥芯轉(zhuǎn)到藏球室中,密封面磨損;
5、 啟閉時(shí),球面與密封座脫離,無(wú)任何接觸,所以開(kāi)關(guān)輕巧,啟閉力矩比球閥及其它閥門(mén)小得多;
6、 關(guān)閉時(shí),關(guān)閉瞬間球面與閥座的運(yùn)動(dòng),具有剪切作用,能除去密封面上的粘連物結(jié)垢,密封嚴(yán)緊可靠;
7、 密封鎖緊機(jī)構(gòu)是固定軸偏心夾緊,能強(qiáng)制補(bǔ)償,自動(dòng)鎖緊,所以球閥承壓能力強(qiáng),耐高壓、高溫密封性能好。
