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
