博世力士樂高頻響閥和伺服閥,4WEH22Y31-7X/6HG24N9ETK4,REXROTH伺服閥
博世力士樂高頻響閥和伺服閥的主閥一般來說和換向閥一樣是滑閥結(jié)構(gòu)，只不過閥芯的換向不是靠電磁鐵來推動(dòng)，而是靠前置閥輸出的液壓力來推動(dòng)，這一點(diǎn)和電液換向閥比較相似，只不過電液換向閥的前置閥是電磁換向閥，而伺服閥的前置閥是動(dòng)態(tài)特性比較好的噴嘴擋板閥或射流管閥。 也就是說，伺服閥的主閥是靠前置閥的輸出壓力來控制的，而前置閥的壓力則來自于伺服閥的入口p，假如p口的壓力不足，前置閥就不能輸出足夠的壓力來推動(dòng)主閥芯動(dòng)作。
