全通徑雙偏心(xīn)半球閥(fá)
全通(tōng)徑雙(shuāng)偏心(xīn)半球閥說(shuō)明:
bq347型(xíng)為蝸(wō)輪傳動,兩(liǎng)端法(fǎ)蘭連(lián)接全(quán)通徑(jìng)雙偏心式(shì)半球閥。可(kě)廣泛用(yòng)于(yú)市政、冶金(jīn)、燃氣、石油化工(gōng)、電力(lì)行(háng)業(yè)的管(guǎn)線閥(fá)遠距(jù)離輸送要求。具有下列優(yōu)點(diǎn):
1、 全(quán)通徑屬于直通(tōng)式,閥(fá)體通(tōng)道與管線連接(jiē)的(de)管道成直管(guǎn)相通,截面(miàn)積相(xiàng)等,中間無(wú)任何阻礙的地(dì)方,所以該閥稱為大流(liú)量(liàng)直通閥。選(xuǎn)用不同的(de)材(cái)質(zhì)可(kě)以達到(dào)各行(háng)業的要求(qiú);
2、 操作簡便(biàn),啟閉(bì)迅速(sù)全開(kāi)、隻要(yào)旋轉(zhuǎn)90°即可達到(dào)方便(biàn)于遠離控(kòng)制,長距離管線輸送(sòng),易于(yú)實現事故(gù)的(de)緊(jǐn)急處(chù)理;
3、 适用于含雜(zá)質(zhì),有結(jié)晶析出(chū)或含有沉澱(diàn)的(de)介質(zhì),不像
截止閥、
閘(zhá)閥(fá)那樣,它(tā)不存(cún)在存(cún)有介質(zhì)的死角(jiǎo),不會(huì)發生密封洩漏故障(zhàng);
4、 密封(fēng)面開(kāi)啟後(hòu),閥(fá)芯轉到(dào)藏球室中,密封(fēng)面磨(mó)損小;
5、 啟閉(bì)時,球(qiú)面與密封(fēng)座脫(tuō)離,無(wú)任何接觸(chù),所以開關(guān)輕巧,啟閉(bì)力矩(jǔ)比球閥及(jí)其它(tā)閥門小(xiǎo)得多;
6、 關閉時,關閉(bì)瞬間(jiān)球面(miàn)與閥(fá)座的運動,具有剪切(qiē)作用,能除(chú)去密(mì)封面上(shàng)的粘連(lián)物結(jié)垢(gòu),密封嚴緊可靠;
7、 密封鎖(suǒ)緊機(jī)構是固定軸(zhóu)偏(piān)心(xīn)夾緊,能(néng)強制補償,自動鎖緊,所以球閥承壓能(néng)力強,耐高壓、高溫(wēn)密封性能好。
