不锈钢电动四通换向球阀为X形垂直通道的球阀,它的特点是球体的两条通道为X形布置,四个通道口径均布于球体赤道圆周截面上,厂家电动四通球阀当球体沿顺时针旋转90时,能使相邻的两个通道实现两两互通。 Features Four-way direction changeable ball valve is a kind of ball valve with X-pattern vertical bore.It s feature is, the ball valve s two bores
are arranged to be X-pattern ,and its four bores are connected to each other two of adjacent bores can be connected to each other. 1.本阀门系列可配置多种驱动装置:
This ball valve can be equipped with several types of operation device. 2.四通球阀介质流向原理:
如图所示,“LL’’型四通球阀只需操作板手或执行器将球体转动90’,可同时对两种介质的流向进行切换,即方便而迅速,实现一阀多用的效果。
