比例閥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,而是靠前置級閥輸出的液壓力來推動,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級閥是電磁換向閥,而伺服閥的前置級閥是動態(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級閥的輸出壓力來控制的,而前置級閥的壓力則來自于伺服閥的入口p,假如p口的壓力不足,前置級閥就不能輸出足夠的壓力來推動主閥芯動作。而我們知道,當(dāng)負(fù)載為零的時候,如果四通滑閥完全打開,p口壓力=t口壓力+閥口壓力損失(忽略油路上的其它壓力損失),如果閥口壓力損失很小,t口壓力又為零,那么p口的壓力就不足以供給前置級閥來推動主閥芯,整個伺服閥就失效了。所以伺服閥的閥口做得偏小,即使在閥口全開的情況下,也要有一定的壓力損失,來維持前置級閥的正常工作。伺服閥其實(shí)缺點(diǎn)極多:能耗浪費(fèi)大、容易出故障、抗污染能力差、價格昂貴等等等等,好處只有一個:動態(tài)性能是所有液壓閥中最高的。就憑著這一個優(yōu)點(diǎn),在很多對動態(tài)特性要求高的場合不得不使用伺服閥,如飛機(jī)火箭的舵機(jī)控制、汽輪機(jī)調(diào)速等等。動態(tài)要求低一點(diǎn)的,基本上都是比例閥的天下了。一般說來,好像伺服系統(tǒng)都是閉環(huán)控制,比例多用于開環(huán)控制;其次比例閥類型要多,有比例壓力、流量控制閥等,控制比伺服要靈活一些。從他們內(nèi)部結(jié)構(gòu)看,伺服閥多是零遮蓋,比例閥則有一定的死區(qū),控制精度要低,響應(yīng)要慢。但從發(fā)展趨勢看,特別在比例方向流量控制閥和伺服閥方面,兩者性能差別逐漸在縮小,另外比例閥的成本比伺服閥要低許多,抗污染能力也強(qiáng)!
