(分流,合流)进口气动螺纹三通球阀是一种三通道的回转型球阀,阀芯有L型和T型,根据不同的工况,任何一个管道都可以作为入进口气动螺纹三通球阀2.jpg口或出口。L型阀是对三条管道中的两条管道进行切除,T型阀实现把三条连通管道进行合流与分流 RETZ (L type, T type) The inlet pneumatic flange three-way ball valve is a three-way rotary ball valve. The valve cores are L type and T type. According to different working conditions, any pipe can be used as the inlet or outlet. L valve is used to cut two of the three pipes, while T valve is used to combine and separate the three connected pipes

特点Characteristic进口气动螺纹三通球阀3.jpg

阀芯孔道有L型和T型两种结构形式,采用控制阀芯旋转角度,改变阀芯孔道与管道口的连接状态,可实现对三条支管不同的组合控制 There are two types of valve core channels, L-type and T-type. By controlling the rotation angle of the valve core and changing the connection state of the valve core channel and the pipe port, different combined control of the three branch pipes can be achieved

两阀座密封能实现对管道中介质流向的切换。也能使相互垂直的两个通道连通或关闭 The two valve seat seals can switch the flow direction of the medium in the pipeline. It can also connect or close two mutually perpendicular channels

四阀座密封不仅可实现介质流向的切换,也可使三个通道相互连通,同时可关闭任意一个通道,使另外两个通道连通,灵活控制管路是介质的合流或分流 The four valve seat seal can not only switch the flow direction of the medium, but also connect the three channels. At the same time, it can close any channel to connect the other two channels. It can flexibly control the converging or diverging flow of the medium in the pipeline
