概述
三通球阀系列对介质流向的不同切换要求可分为Q44L型与Q45T型，
如图A．L型可实现对介质流向进行切换，亦可使相互垂直的两个通道连通或关闭。
如图B．T型可实现对介质的分流或混流，不仅可以实现介质流向的切换，
也可使三个通道互相连通，还可以关闭任一通道，连通另外两个通道。
本阀门具有结构紧凑．造形美观．密封性能好等特点。
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

三通球阀用于分流或汇台流通，是具有=面或四面阀座的多通口球蠲．任一通口可用作入
口而无泄漏。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

※注：系列球阀结构长度及连接法兰尺寸可根据用户要求设计制造。
※注：数据xxx，xxx分别是气动执行器双作用式，单作用式（弹簧复位）。
※洼：*根据不同阀门扭矩、使用介质适配的执行器型号可能有所不同．相关尺寸随之变化。
Note：The structural length and connecting flange size of ball valve series can be designed and manufactured users'
requirements.
Note：Data x x x/x x x represent respectiwly the double-acting/single-acting type(spring reposition) of pneumatic actuator
Note：*The relative sizes are subject to change responding to the difference in valve to torque, medium and actuator model.
