流向示意圖Flow diagram:
三通球閥用于分流或匯合流通，是具有二面或四面閥門(mén)的多通口球閥，任何一通口可用作入口而無(wú)泄漏。
三通即可制成L型通口也可制成T型通口。
Three-way ball valve is used for diffluence of confluent circulation with two-side or four-side
valve base embodying multiple Channels, All the channels can be used as entrance, with no
leakage. The three-way can be made to L-shaped channed or T- shaped channel.
