一、產(chǎn)品特點(diǎn)： ????? 不銹鋼電動(dòng)四通換向球閥為X形垂直通道的球閥，它的特點(diǎn)是球體的兩條通道為X形布置，四個(gè)通道口徑均布于球體赤道圓周截面上，當(dāng)球體沿順時(shí)針旋轉(zhuǎn)90時(shí)，能使相鄰的兩個(gè)通道實(shí)現(xiàn)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(qū)動(dòng)裝置：
This ball valve can be equipped with several types of operation device. 2.四通球閥介質(zhì)流向原理：
如圖所示，“LL’’型四通球閥只需操作板手或執(zhí)行器將球體轉(zhuǎn)動(dòng)90’，可同時(shí)對(duì)兩種介質(zhì)的流向進(jìn)行切換，即方便而迅速，實(shí)現(xiàn)一閥多用的效果。
