當(dāng)前位置:上海挺揚(yáng)自控閥門制造有限公司> 供求商機(jī)> 不銹鋼電動(dòng)四通換向球閥
一、產(chǎn)品特點(diǎn)Features:
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。
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。
2-way flow valve media theory:
As shown, "LL''ball-type four-way wrench or simply operate the actuator to rotate sphere 90 ', while the two media can flow switch, which easily and quickly, to achieve a multi-valve effect .
