諾冠NORGREN溢流閥型號R17-801-RGLA

NORGREN溢流閥的設(shè)定壓力由與輸入電信號成比例的電磁力決定。當(dāng)輸入一電信號給比例電磁鐵時(shí)，比例電磁鐵將輸出相應(yīng)的電磁力推動先導(dǎo)閥中的針閥。來自系統(tǒng)的壓力也作用于針閥上并與電磁力相平衡，如果系統(tǒng)壓力升高而超過對應(yīng)著的電磁力設(shè)定值，先導(dǎo)閥中的針閥打開系統(tǒng)壓力將回復(fù)至設(shè)定值。從而系統(tǒng)壓力基本上保持恒定。由于比例電磁鐵的zui大推力是一定的，所以不同壓力等級要通過改變閥座孔徑來獲得。而不象普通溢流閥那樣靠更換不同剛度的調(diào)節(jié)彈簧來得到。
NORGREN溢流閥右端有一阻尼活塞3（阻尼活塞一方面在錐閥開啟或閉合時(shí)起阻尼作用，用來提高錐閥工作的穩(wěn)定性；另一方面用來保證錐閥開啟后不會傾斜）。進(jìn)口的壓力油（壓力為P）可以由此活塞的徑向間隙進(jìn)入活塞底部，形成一個(gè)向左的液壓力F=P稟（A為活塞底部面積）。當(dāng)作用在底部的液壓力F大于彈簧力時(shí)，錐閥閥口打開，油液由錐閥口經(jīng)回流口溢回油箱。只要閥口打開，有油液流經(jīng)溢流閥，溢流閥入口的壓力就基本保持恒定。
