全通徑雙(shuang)偏心半球閥
全通徑雙偏心半(bàn)球閥說明:
BQ347型為蝸(wo)輪傳動,兩端法蘭(lán)連接全通徑雙偏(pian)心式半球閥。可廣(guang)泛用于市政、冶金(jin)、燃氣、石油化工、電(diàn)力行業的管線🙇🏻閥(fa)遠距離輸送要求(qiú)。具有下列優點:
1、 全(quan)通徑屬于直通式(shi),閥體通道與管線(xian)連接的管道成直(zhí)管相🌈通,截面積相(xiàng)等,中間無任何阻(zǔ)礙的地方,所以該(gai)閥稱為大流量直(zhí)👉通閥。選用不同的(de)材質可✨以達到👅各(gè)行業的要求;
2、 操作(zuò)簡便,啟閉迅速全(quán)開、隻要旋轉90°即可(kě)達到方便于遠離(lí)✔️控制⭐,長距離管線(xiàn)輸送,易于實現事(shi)故的緊急處🌈理;
3、 适(shi)用于含雜質,有結(jié)晶析出或含有沉(chen)澱的介質,不像
截(jié)止閥、
閘閥那樣,它(ta)不存在存有介質(zhì)的死角,不會發生(sheng)密封洩☎️漏故障;
4、 密(mì)封面開啟後,閥芯(xīn)轉到藏球室中,密(mì)封面磨損小;
5、 啟閉(bì)時,球面與密封座(zuo)脫離,無任何接觸(chù),所以開關輕巧,啟(qǐ)閉力矩比球閥及(jí)其它閥門小得多(duo);
6、 關閉時,關閉瞬間(jiān)球面與閥座的運(yùn)動,具有剪切作用(yòng)🥰,能除去🐇密封面上(shang)的粘連物結垢,密(mì)封嚴緊可靠;
7、 密封(fēng)鎖緊機構是固定(ding)軸偏心夾緊,能強(qiang)制補償,自動鎖緊(jin),所以球閥承壓能(neng)力強,耐高壓、高溫(wēn)密封性能好。
