圖文講解液壓系統(tǒng)溢流閥分類與工作原理
液壓系統(tǒng)的溢流閥按照結(jié)構(gòu)不同,溢流閥可分爲直動式和先導(dǎo)式兩種。先導(dǎo)式溢流閥與電磁換向閥複合可構(gòu)成電磁溢流閥,先導(dǎo)式溢流閥與單向閥複合可構(gòu)成卸荷溢流閥。下面給大家介紹下液壓系統(tǒng)溢流閥的分類以及工作原理。
液壓系統(tǒng)分類及詳細說明:
直動式溢流閥:
直動式溢流閥有錐閥式、球閥式、滑閥式三種結(jié)構(gòu)。下圖爲滑閥式結(jié)構(gòu)的直動式溢流閥的工作原理。
壓力油經(jīng)阻尼孔進入閥芯底部,當作用在閥芯上的作用力大于彈簧力時,閥口打開,使油液溢流。通過轉(zhuǎn)動手輪可以調(diào)節(jié)彈簧預(yù)緊力,從而調(diào)節(jié)溢流閥的開啓壓力,通過更換不同剛度的彈簧可以調(diào)整溢流閥的調(diào)壓范圍。直動式溢流閥結(jié)構(gòu)簡單,靈敏度高,但不適于在高壓大流量的場合。
下圖爲溢流閥的剖面圖,原理與上圖相同。
先導(dǎo)式溢流閥:
在中高壓和大流量場合中,一般采用先導(dǎo)式溢流閥,包含先導(dǎo)閥和主閥兩部分。下圖爲先導(dǎo)式溢流閥的工作原理。
如上圖所示,上端爲先導(dǎo)閥,下端爲主閥,壓力油經(jīng)阻尼孔進入主閥上腔和先導(dǎo)閥右腔。壓力不高時,主閥上下兩腔壓力相等,在彈簧力作用下,先導(dǎo)閥和主閥都爲關(guān)閉狀態(tài);當壓力升高到可以打開先導(dǎo)閥芯時,油液經(jīng)阻尼孔在主閥上下兩腔産生壓差,將主閥芯推開,油液溢流。在先導(dǎo)閥右端有個遙控口,可以接二位換向閥控制溢流閥是否卸荷,也可以接個調(diào)定壓力較小的溢流閥進行遠程調(diào)壓。通過調(diào)節(jié)先導(dǎo)閥彈簧的預(yù)緊力可調(diào)節(jié)溢流閥的調(diào)定壓力,而主閥的彈簧剛度較小,隻起複位主閥芯的作用。下圖爲闆式先導(dǎo)溢流閥的剖面圖及其符號。
說明:該閥的先導(dǎo)閥的洩露油爲內(nèi)洩,x爲遙控口,可以進行遠程調(diào)壓。
電磁溢流閥:
電磁溢流閥是在先導(dǎo)溢流閥的基礎(chǔ)上加二位電磁換向閥,通過控制先導(dǎo)閥的控制油路是否通油箱,以實現(xiàn)液壓系統(tǒng)的卸荷和加載。下圖爲電磁溢流閥的應(yīng)用場合。電磁閥不得電時,溢流閥發(fā)揮作用;當電磁閥得電時,系統(tǒng)卸荷。
卸荷溢流閥:
卸荷溢流閥又稱爲單向溢流閥,下圖爲卸荷溢流閥的結(jié)構(gòu)和職能符號。當系統(tǒng)壓力不高時,單向閥打開,泵向系統(tǒng)供油;當壓力升高,溢流閥開啓溢流,系統(tǒng)卸荷,此時單向閥關(guān)閉。卸荷溢流閥可以實現(xiàn)系統(tǒng)的自動加載和卸荷,常與蓄能器配合使用。
以上就是液壓系統(tǒng)溢流閥的詳細分類及說明,提醒大家,需要特別注意的是,液壓系統(tǒng)中容易産生噪聲的元件一般認爲是泵和閥,閥中又以溢流閥和電磁換向閥等爲主。
