概述
三通球閥系列對介質(zhì)流向的不同切換要求可分為Q44L型與Q45T型，
如圖A．L型可實現(xiàn)對介質(zhì)流向進(jìn)行切換，亦可使相互垂直的兩個通道連通或關(guān)閉。
如圖B．T型可實現(xiàn)對介質(zhì)的分流或混流，不僅可以實現(xiàn)介質(zhì)流向的切換，
也可使三個通道互相連通，還可以關(guān)閉任一通道，連通另外兩個通道。
本閥門具有結(jié)構(gòu)緊湊．造形美觀．密封性能好等特點。
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

三通球閥用于分流或匯臺流通，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.
With two-sid. or four-sida valve base embodying multiple channels All
the channals can be used as e.t,ance. with no leakage The three-way
can be made to L-shaped channel or T-shaped channel
