REXROTH閥SEH系列介紹
概述
SEH型方向閥是帶有電液驅(qū)動(dòng)的方向座閥。根據(jù)訂購(gòu)版本的不同，可以通過一個(gè)或兩個(gè)通道進(jìn)行切換或關(guān)閉。
方向閥基本上由外殼（1）、先導(dǎo)操作的單向閥安裝組件（2）、先導(dǎo)控制閥（3）以及用于先導(dǎo)油供應(yīng)的封堵塞組成。該閥不受方向影響，具有自由流動(dòng)性，并且根據(jù)先導(dǎo)控制閥的切換位置和主閥中的壓力比，以無泄漏的方式開啟或封閉。
功能
閥的功能依賴于壓力。壓縮彈簧（4）的力以及控制室（5）中由壓力產(chǎn)生的力作用于關(guān)閉方向，而通道A和B中由壓力產(chǎn)生的力作用于閥芯（6）的開啟方向，閥芯帶有密封。由開啟和關(guān)閉力產(chǎn)生的合力方向決定單向閥安裝組件（2）的切換位置。根據(jù)所選的先導(dǎo)油供應(yīng)，先導(dǎo)壓力施加和/或卸載通過先導(dǎo)控制閥（3）實(shí)現(xiàn)。先導(dǎo)油供應(yīng)通過通道A、B、P或X中的最高壓力實(shí)現(xiàn)，并通過單向閥（7）進(jìn)行保護(hù)。
General
The SEH type directional valves are directional seat valves with electro-hydraulic actuation. Here, depending on the order version, it can be switched or switched off via one or two channels.
The directional valve basically consists of a housing (1), a pilot operated check valve installation set (2), pilot control valve (3) as well as blanking plugs for the pilot oil supply. The valve is free-flowing, independent from the direction, and is opened or blocked in a leakage-free manner depending on the switching position of the pilot control valve and the pressure ratio in the main valve.
Function
The function of the valve is pressure-dependent. The force of the compression spring (4) as well as the force generated by pressure in the control chamber (5) take effect in the closing direction, while the forces generated by pressure in the channels A and B take effect in the opening direction of the valve spool (6) with spool sealing. The direction of action of the resulting force from the opening and closing forces determines the switching position of the check valve installation sets (2). The pilot pressure application and/or unloading is implemented via the pilot control valve (3) depending on the selected pilot oil supply. The pilot oil supply is implemented via the respective highest pressure from the channels A, B, P or X and is secured via a check valve (7).
