1、產(chǎn)品概述及特點(diǎn)
電動(dòng)球閥是部分旋轉(zhuǎn)類(lèi)球閥，旋轉(zhuǎn)90°即可全關(guān)全開(kāi)，與相同規(guī)格的閘閥和截止閥比較，球閥體積小、重量輕、功能強(qiáng)大、可靠性高、便于管道安裝等。密封性能優(yōu)良，流通能力大，流阻系數(shù)小，結(jié)構(gòu)簡(jiǎn)單、維修方便、使用壽命長(zhǎng)。閥體通道和連接管徑相等并成一直徑，介質(zhì)幾乎可以毫無(wú)損失的流過(guò)。產(chǎn)品通常用于密封要求嚴(yán)格的場(chǎng)合，除控制氣體、液體、蒸汽介質(zhì)外，還適宜控制污水和含有纖維性雜質(zhì)的介質(zhì)。
球閥是一種重要的閥類(lèi)，在石油化工和長(zhǎng)輸管線等領(lǐng)域有廣泛應(yīng)用。它的關(guān)閉件是一個(gè)帶孔的部分球體，球體隨閥桿轉(zhuǎn)動(dòng)，實(shí)現(xiàn)閥門(mén)的開(kāi)啟或關(guān)閉。流向可任意，可調(diào)范圍廣，能用于高壓和大口徑場(chǎng)合，控制高粘度，帶有纖維和細(xì)顆粒的介質(zhì)。
