一、產品特點:
上明牌不銹鋼電動四通換向球閥為X形垂直通道的球閥,它的特點是球體的兩條通道為X形布置,四個通道口徑均布于球體赤道圓周截面上,當球體沿順時針旋轉90時,能使相鄰的兩個通道實現兩兩互通。
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.本閥門系列可配置多種驅動裝置: This ball valve can be equipped with several types of operation device.
2.四通球閥介質流向原理: 如圖所示,“LL’’型四通球閥只需操作板手或執行器將球體轉動90’,可同時對兩種介質的流向進行切換,即方便而迅速,實現一閥多用的效果。
