概述 三通球閥系列對(duì)介質(zhì)流向的不同切換要求可分為Q44L型與Q45T型， 如圖A．L型可實(shí)現(xiàn)對(duì)介質(zhì)流向進(jìn)行切換，亦可使相互垂直的兩個(gè)通道連通或關(guān)閉。 如圖B．T型可實(shí)現(xiàn)對(duì)介質(zhì)的分流或混流，不僅可以實(shí)現(xiàn)介質(zhì)流向的切換， 也可使三個(gè)通道互相連通，還可以關(guān)閉任一通道，連通另外兩個(gè)通道。 本閥門具有結(jié)構(gòu)緊湊．造形美觀．密封性能好等特點(diǎn)。 Summary According to different switching requirements to the flow direction of medium, three-way ball valve series can be divi-ded into two types:Q44L ａnd Q457. As shown in Fig. A, L-type cannot oniy switch the flow direction of medium but o-nly connect or close two orthogonal pipes. As shown in Fig.B, T type cannot only switch the flow direction of medium, bu-t also connect three pipes with each other, or close any one of three ways and connect the other two pipes. This valve ha-s such advantages as compact structu re, beautiful outline, a-nd good sealing performance, etc 三通球閥介質(zhì)流向示意圖 Sketch of Medium Flow-direction of Three-way BallValve 三通球閥用于分流或匯臺(tái)流通，是具有=面或四面閥座的多通口球蠲．任一通口可用作入 口而無泄漏。三通既可制成L型通口也可制成T型通口。 Three-way ball valve is used for diffluence or confHlue.t circulalio.
