全通徑雙(shuāng)偏心(xīn)半球閥說(shuō)明:
bq347型為蝸輪傳(chuán)動,兩端法(fǎ)蘭連(lián)接全(quán)通徑雙偏(piān)心式半(bàn)球(qiú)閥。可(kě)廣泛(fàn)用于市政(zhèng)、冶金、燃氣、石油(yóu)化工(gōng)、電(diàn)力行(háng)業(yè)的管線(xiàn)閥(fá)遠距離輸送要求。具(jù)有下列優(yōu)點:
1、 全通徑屬(shǔ)于直通(tōng)式,閥體通道與管線(xiàn)連接(jiē)的管(guǎn)道成直管相通(tōng),截面積(jī)相等,中(zhōng)間無(wú)任何阻礙的地方(fāng),所以(yǐ)該(gāi)閥稱(chēng)為大(dà)流量(liàng)直通閥(fá)。選(xuǎn)用不(bú)同的(de)材(cái)質可以(yǐ)達到(dào)各行(háng)業的(de)要求(qiú);
2、 操作(zuò)簡便,啟閉(bì)迅速(sù)全開(kāi)、隻要旋(xuán)轉90°即可(kě)達到方便于遠離控制,長距離(lí)管線(xiàn)輸送(sòng),易于(yú)實現事故(gù)的緊急處理(lǐ);
3、 适用于(yú)含雜質,有結晶(jīng)析出或含(hán)有沉(chén)澱的介質,不像
截止閥、
閘(zhá)閥那(nà)樣,它(tā)不存在存(cún)有介質的(de)死角,不會發生(shēng)密封(fēng)洩漏(lòu)故(gù)障(zhàng);
4、 密(mì)封面開啟後(hòu),閥芯(xīn)轉到藏球室中,密封面磨損小(xiǎo);
5、 啟閉(bì)時,球面與(yǔ)密封座脫(tuō)離,無任何(hé)接觸,所以開關(guān)輕(qīng)巧(qiǎo),啟閉(bì)力矩(jǔ)比球閥及(jí)其(qí)它閥(fá)門(mén)小得(dé)多;
6、 關閉時,關閉(bì)瞬間球面與閥(fá)座的(de)運(yùn)動,具有(yǒu)剪切作用(yòng),能除去密封面上的(de)粘連物結垢(gòu),密(mì)封嚴緊可靠;
7、 密(mì)封鎖緊機(jī)構是固定(dìng)軸偏(piān)心夾緊,能強(qiáng)制(zhì)補償(cháng),自動(dòng)鎖緊,所(suǒ)以(yǐ)球閥承壓(yā)能力(lì)強,耐高(gāo)壓、高溫(wēn)密封性能好。
