液控單向閥
液控單向閥也稱(chēng)閉鎖閥或保壓閥,用以防止油液反向流動(dòng)。但在液壓回路中需要油流反向流動(dòng)時(shí)又可利用控制油壓,打開(kāi)單向閥,使油流在兩個(gè)方向都可流動(dòng)。液控單向閥采用 錐形閥芯,因此密封性能好。在要求封閉油路時(shí),可用此閥作為油路的單向鎖緊而起保壓作用。液控單向閥控制油的泄漏方式有內(nèi)泄式和外泄式二種。在油流反向出 口無(wú)背壓的油路中可用內(nèi)泄式;否則需用外泄式,以降低控制油壓力。
液控單向閥是依靠控制流體壓力,可以使單向閥反向流通的閥。這種閥在煤礦機(jī)械的液壓支護(hù)設(shè)備中占有較重要的地位。液控單向閥與普通單向閥不同之處是多了一個(gè)控制油路K,當(dāng)控制油路未接通壓力油液時(shí),液控單向閥就象普通單向閥一樣工作,壓力油只從進(jìn)油口流向出油口,不能反向流動(dòng)。當(dāng)控制油路油控制壓力輸入時(shí),活塞頂桿在壓力油作用下向右移動(dòng),用頂桿頂開(kāi)單向閥,使進(jìn)出油口接通。若出油口大于進(jìn)油口就能使油液反向流動(dòng)。

壓力繼電器是利用液體的壓力來(lái)啟閉電氣觸點(diǎn)的液壓電氣轉(zhuǎn)換元件。當(dāng)系統(tǒng)壓力達(dá)到壓力繼電器的調(diào)定值時(shí),發(fā)出電信號(hào),使電氣元件(如電磁鐵、電機(jī)、時(shí)間繼電器、電磁離合器等)動(dòng)作,使油路卸壓、換向,執(zhí)行元件實(shí)現(xiàn)順序動(dòng)作,或關(guān)閉電動(dòng)機(jī)使系統(tǒng)停止工作,起安全保護(hù)作用等。 壓力繼電器有柱塞式、膜片式、彈簧管式和波紋管式四種結(jié)構(gòu)形式。下面對(duì)柱塞式壓力繼電器的工作原理作一介紹: 當(dāng)從繼電器下端進(jìn)油口3進(jìn)入的液體壓力達(dá)到調(diào)定壓力值時(shí),推動(dòng)柱塞2上移,此位移通過(guò)杠桿放大后推動(dòng)微動(dòng)開(kāi)關(guān)4動(dòng)作。改變彈簧1的壓縮量,可以調(diào)節(jié)繼電器的動(dòng)作壓力。 應(yīng)用場(chǎng)合:用于安全保護(hù)、控制執(zhí)行元件的順序動(dòng)作、用于泵的啟閉、用于泵的卸荷。 注意: 壓力繼電器必須放在壓力有明顯變化的地方才能輸出電信號(hào)。若將壓力繼電器放在回油路上,由于回油路直接接回油箱,壓力也沒(méi)有變化,所以壓力繼電器也不會(huì)工作。

節(jié)流閥是通過(guò)改變節(jié)流截面或節(jié)流長(zhǎng)度以控制流體流量的閥門(mén)。將節(jié)流閥和單向閥并聯(lián)則可組合成單向節(jié)流閥。節(jié)流閥和單向節(jié)流閥是簡(jiǎn)易的流量控制閥,在定量泵液壓系統(tǒng)中,節(jié)流閥和溢流閥配合,可組成三種節(jié)流調(diào)速系統(tǒng),即進(jìn)油路節(jié)流調(diào)速系統(tǒng)、回油路節(jié)流調(diào)速系統(tǒng)和旁路節(jié)流調(diào)速系統(tǒng)。節(jié)流閥沒(méi)有流量負(fù)反饋功能,不能補(bǔ)償由負(fù)載變化所造成的速度不穩(wěn)定,一般僅用于負(fù)載變化不大或?qū)λ俣确€(wěn)定性要求不高的場(chǎng)合。
對(duì)節(jié)流閥的性能要求是:
·流量調(diào)節(jié)范圍大,流量一壓差變化平滑;
·內(nèi)泄漏量小,若有外泄漏油口,外泄漏量也要??;
·調(diào)節(jié)力矩小,動(dòng)作靈敏。
