概述

三通球閥系列對介質流向的不同切換要求可分為Q44L型與Q45T型，

如圖A．L型可實現對介質流向進行切換，亦可使相互垂直的兩個通道連通或關閉。

如圖B．T型可實現對介質的分流或混流，不僅可以實現介質流向的切換，

也可使三個通道互相連通，還可以關閉任一通道，連通另外兩個通道。

本閥門具有結構緊湊．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
