進(jìn)口電動(dòng)法蘭三通球閥能實(shí)現(xiàn)對(duì)管道中介質(zhì)流向的切換，也能使相互垂直的兩個(gè)通道連通或關(guān)閉。四閥座密封三通球閥不僅可實(shí)現(xiàn)介質(zhì)流向的切換，也可使三個(gè)通道相互連通，現(xiàn)時(shí)也可關(guān)閉任一通道，使另外兩個(gè)通道連通，靈活控制管路中介質(zhì)的合流或分流
retz The imported electric flange three-way ball valve can switch the flow direction of the medium in the pipeline, and can also connect or close two perpendicular channels. The four seat sealed three-way ball valve not only switches the flow direction of the medium, but also enables the three channels to be interconnected. Currently, any channel can also be closed to connect the other two channels, flexibly controlling the convergence or diversion of the medium in the pipeline
功能介紹 Function introduction
進(jìn)口電動(dòng)法蘭三通球閥用于換向分流或匯合流通，是具有二面或四面閥座的多通口球閥，任一通口可用作入口而無(wú)泄漏。三通既可制成L型通口也可制成T型通口 RETZ Three-way ball valve is used for reversing and diverting or converging flow. It is a multi-port ball valve with two or four seats. Any port can be used as an inlet without leakage. Tees can be made into L-shaped ports or T-shaped ports
L型流道的三通4面閥座球閥，采用2面閥座，受力平衡，保證閉止通道的可靠密封。主要用于流路的換向 Three-way four-side valve seat ball valve with L-shaped flow passage adopts two-side valve seat, with balanced stress, to ensure reliable sealing of the closing channel. Mainly used for commutation of flow path
T型流道的三通4面閥座，由于采用4面閥座，亞力平衡，保證閉止通道的可靠密封。主要用于分流、混流、換向以及三通道的完全開(kāi)放 The three-way four-face valve seat of the T-shaped flow passage is balanced by Yali due to the four-face valve seat, which ensures the reliable sealing of the closing channel. It is mainly used for shunt, mixed flow, commutation and full opening of three channels
