一種是開關(guān)控制：要么全開、要么全關(guān)，流量要么最大、要么最小，沒有中間狀態(tài)，如普通的電磁直通閥、電磁換向閥、電液換向閥。
減壓閥是通過調(diào)節(jié),將進(jìn)口壓力減至某一需要的出口壓力,并依靠介質(zhì)本身的能量,使出口壓力自動(dòng)保持穩(wěn)定的閥門。從流體力學(xué)的觀點(diǎn)看,減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件,即通過改變節(jié)流面積,使流速及流體的動(dòng)能改變,造成不同的壓力損失,從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié),使閥后壓力的波動(dòng)與彈簧力相平衡,使閥后壓力在一定的誤差范圍內(nèi)保持恒定。
