壓力控制
按用途分為溢流閥﹑減壓閥和順序閥。⑴溢流閥:能控制液壓系統(tǒng)在達(dá)到調(diào)定壓力時(shí)保持恒定狀態(tài)。用於過載保護(hù)的溢流閥稱為安全閥。當(dāng)系統(tǒng)發(fā)生故障,壓力升高到可能造成破壞的限定值時(shí),閥口會(huì)打開而溢流,以系統(tǒng)的安全。⑵減壓閥:能控制分支回路得到比主回路油壓低的穩(wěn)定壓力。減壓閥按它所控制的壓力功能不同,又可分為定值減壓閥(輸出壓力為恒定值)﹑定差減壓閥(輸入與輸出壓力差為定值)和定比減壓閥(輸入與輸出壓力間保持定的比例)。⑶順序閥:能使個(gè)執(zhí)行元件(如液壓缸﹑液壓馬達(dá)等)動(dòng)作以后,再按順序使其他執(zhí)行元件動(dòng)作。油泵產(chǎn)生的壓力推動(dòng)液壓缸1運(yùn)動(dòng),同時(shí)通過順序閥的進(jìn)油口作用在面積A 上,當(dāng)液壓缸1運(yùn)動(dòng)*成后,壓力升高,作用在面積A 的向上推力大於彈簧的調(diào)定值后,閥芯上升使進(jìn)油口與出油口相通,使液壓缸2運(yùn)動(dòng)。
折疊編輯本段流量控制
利用調(diào)節(jié)閥芯和閥體間的節(jié)流口面積和它所產(chǎn)生的局部阻力對(duì)流量進(jìn)行調(diào)節(jié),從而控制執(zhí)行元件的運(yùn)動(dòng)速度。流量控制閥按用途分為 5種。⑴節(jié)流閥:在調(diào)定節(jié)流口面積后,能使載荷壓力變化不大和運(yùn)動(dòng)均勻性要求不高的執(zhí)行元件的運(yùn)動(dòng)速度基本上保持穩(wěn)定。⑵調(diào)速閥:在載荷壓力變化時(shí)能保持節(jié)流閥的進(jìn)出口壓差為定值。這樣,在節(jié)流口面積調(diào)定以后,不論載荷壓力如何變化,調(diào)速閥都能保持通過節(jié)流閥的流量不變,從而使執(zhí)行元件的運(yùn)動(dòng)速度穩(wěn)定。⑶分流閥:不論載荷大小,能使同油源的兩個(gè)執(zhí)行元件得到相等流量的為等量分流閥或同步閥;得到按比例分配流量的為比例分流閥。⑷集流閥:作用與分流閥相反,使流入集流閥的流量按比例分配。⑸分流集流閥:兼具分流閥和集流閥兩種功能。
要求
1)動(dòng)作靈活,作用,工作時(shí)沖擊和振動(dòng)小,噪聲小,使用壽命長(zhǎng)。
2)流體通過液壓閥時(shí),壓力損失小;閥口關(guān)閉時(shí),密封,內(nèi)泄漏小,無外泄漏。
3)所控制的參量(壓力或流量)穩(wěn)定,受外部干擾時(shí)變化量小。
4)結(jié)構(gòu)緊湊,安裝、調(diào)試、使用、維護(hù)方便,通用性。
