產品簡介
Q644（45）三通球閥 密封性好、裝卸方便、起分流合流作用、使用於這種化工 醫藥 食品行業。 ﹥ 公稱通經：DN15-DN250 ﹥ 壓力範圍：1.0MPa-6.4MPa ﹥ 介質溫度：-20℃250℃ ﹥ 閥體材料：WCB、304、316[1]產品概述
(T)(L)型氣動球閥是由氣動執行機構和三通閥組成，是一種旋轉類切斷調節閥門，具有關閉嚴密，結構緊湊，重量輕，維修方便等優點。泛適用於供水、石化、冶金、礦山、輕紡、能源、造紙、食品、鋼鐵等管路系統中對介質流向進行切換以及對介質的分流或混合流體。[1]產品特點
結構緊湊、啟閉迅速、流道暢通、流體阻力小。密封性能好：利用四面閥座材料聚四氟乙烯彈性變形實現無泄漏密封。一閥多用：任一通口可用作入口而無泄漏，三通既可製成L型通口，也可製成T型通口。維修方便：在系統卸壓後，無需拆下整個閥體就可進行檢查和維修。 介質流向原理三通球閥分L型和T型，介質流通方向見下圖。L型三通球閥適用於介質流向的切換，能使相互垂直的兩個通道連通：T型三通球閥適用於介質的分流、合流 或流向切換，T型孔道可以使三個通道互相連通或使其中兩個通道連通，三通球閥一般採用兩個閥座結構，亦可根據用戶要求採用四閥座結構。[1]相關尺寸
