先導式可阻塞單向閥和成型單元的液壓傳動,在該成
塞.相關聯(lián)的打開表面可通過先導閥控制連接到入口
型單元中使用這種類型的單向閥.可阻塞單向閥包括
具有相關聯(lián)的打開表面和相關聯(lián)的關閉表面的主活
端口或液壓介質(zhì)匯集,使得當壓力切換到液壓介質(zhì)匯
的壓力時,緩解相關聯(lián)的打開表面上的壓力.

性能特點:
先導式單向閥的速度控制閥具有上述特性的閥門,
在接近閥瓣的動作加速,易發(fā)生水錘的沖擊,接近
隔膜型和活塞型兩類,工作原理相同,都是以上下
游壓力差為動力,有導閥控制,使隔膜(活塞)液
全閉時,閥門動作越緩慢越好,于是可在閥瓣上設
過濾網(wǎng),定期檢修及設置旁通管路。水力控制閥分
壓式差動操作,完全由水力自動調(diào)節(jié),從而使主閥
置節(jié)流裝置。另外先導閥的節(jié)流和動作部分要盡量
避免設置特小口徑的孔口,以免堵塞。必要時要加
閥瓣完全開啟或完全關閉或處于調(diào)節(jié)狀態(tài)。
