全通徑(jing)雙偏心(xin)半球閥(fá)說明:
BQ347型(xíng)為蝸輪(lun)傳動,兩(liǎng)端法蘭(lán)連接全(quán)通徑雙(shuāng)偏心式(shì)半球閥(fa)✏️。可💁廣🔴泛(fan)用于市(shì)政、冶金(jīn)、燃氣、石(shi)油化工(gōng)、電力行(hang)💔業的管(guǎn)線閥遠(yuan)🛀🏻距離輸(shū)送要求(qiú)。具有下(xia)列優點(dian):
1、 全通徑(jìng)屬于直(zhí)通式,閥(fa)體通道(dào)與管線(xiàn)連接的(de)管道成(chéng)直管相(xiang)通,截面(mian)積相等(deng),中間無(wú)任何阻(zu)礙的地(dì)方,所以(yǐ)該閥♈稱(chēng)為大流(liú)量直通(tong)閥。選用(yòng)不同的(de)材質可(kě)以達到(dào)💯各行業(yè)的要求(qiú);
2、 操作簡(jian)便,啟閉(bì)迅速全(quan)開、隻要(yào)旋轉90°即(ji)可達到(dao)方便于(yu)遠離控(kòng)制,長距(jù)離管線(xiàn)輸送,易(yi)于實現(xiàn)事故的(de)緊急處(chu)理;
3、 适用(yong)于含雜(zá)質,有結(jié)晶析出(chū)或含有(you)沉澱的(de)介質,不(bú)像
截止(zhǐ)閥、
閘閥(fa)那樣,它(ta)不存在(zai)存有介(jie)質的死(si)角,不會(hui)發生密(mì)封洩漏(lou)⭐故障;
4、 密(mì)封面開(kai)啟後,閥(fá)芯轉到(dào)藏球室(shi)中,密封(feng)面磨損(sǔn)小;
5、 啟閉(bì)時,球面(mian)與密封(fēng)座脫離(lí),無任何(he)接觸,所(suǒ)以開關(guan)輕巧,啟(qi)💰閉力🈚矩(ju)比球閥(fá)及其它(ta)閥門小(xiǎo)得多;
6、 關(guān)閉時,關(guan)閉瞬間(jiān)球面與(yu)閥座的(de)運動,具(jù)有剪切(qie)作用,能(neng)除去㊙️密(mì)封面上(shang)的粘連(lián)物結垢(gou),密封嚴(yán)緊可靠(kao);
7、 密封鎖(suo)緊機構(gòu)是固定(dìng)軸偏心(xīn)夾緊,能(neng)強制補(bu)償,自動(dong)鎖緊,所(suǒ)以球閥(fa)承壓能(neng)力強,耐(nài)高壓、高(gāo)溫密封(fēng)性能好(hǎo)。
