B2P/B3P290/391/490-15/20/25/32G/N B2P/B3P290/391/490-40/50/65/80T/K，B2P/B3P球閥

球閥的工作原理是通過(guò)旋轉(zhuǎn)閥芯來(lái)實(shí)現(xiàn)閥門(mén)的開(kāi)啟或關(guān)閉。球閥的啟閉件是一個(gè)球體，球體繞閥桿的軸線(xiàn)旋轉(zhuǎn)90度，從而控制流體的通斷。當(dāng)球閥旋轉(zhuǎn)到開(kāi)啟位置時(shí)，流體可以通過(guò)球閥；而當(dāng)球閥旋轉(zhuǎn)到關(guān)閉位置時(shí)，球體與閥座緊密接觸，阻止流體通過(guò)。球閥具有開(kāi)關(guān)輕便、體積小、密封可靠、結(jié)構(gòu)簡(jiǎn)單、維修方便等特點(diǎn)，并且適用于多種介質(zhì)，包括含纖維、微小固體顆粒的介質(zhì)。?
