因?yàn)檫@種閥換向沖擊大,所以只允許通過(guò)小流量,不適宜大流量通過(guò);如果運(yùn)動(dòng)部件質(zhì)量大,速度變化范圍較大,換向要求平穩(wěn),流量大干L/rain時(shí),應(yīng)選用換向平穩(wěn)又無(wú)沖擊的電液換向閥;如果系統(tǒng)中具有鎖緊回路,應(yīng)選擇密封性能好的液控單向閥,而不選擇密封性差的換向閥。二壓力控制閥的選取壓力控制閥是帶壓開(kāi)孔機(jī)控制液壓系統(tǒng)的壓力,因此應(yīng)根據(jù)液壓系統(tǒng)的工作狀態(tài)對(duì)壓力的要求和控制閥在系統(tǒng)中的功用來(lái)選取。例如在定量泵節(jié)流調(diào)速系統(tǒng)中,執(zhí)行元件的運(yùn)動(dòng)速度依靠節(jié)流閥控制;為了保持泵的工作壓力基本恒定,應(yīng)選用溢流閥進(jìn)行穩(wěn)壓溢流;為了防止系統(tǒng)過(guò)載,可在泵的出口處并聯(lián)一個(gè)溢流閥,用于保護(hù)泵和整個(gè)系統(tǒng)的安全;若系統(tǒng)中有減壓回路時(shí),必須使用減壓閥將高壓回路的壓力減為低壓;若系統(tǒng)中采用壓力控制各部件的先后順序動(dòng)作時(shí),應(yīng)使用順序閥,將順序閥的壓力調(diào)定為要求的壓力值,從而控制部件的動(dòng)作順序
