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
