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)在達到調(diào)定壓力時保持恒定狀態(tài)。用於過載保護的溢流閥稱為安全閥。當系統(tǒng)發(fā)生故障,壓力升高到可能造成破壞的限定值時,閥口會打開而溢流,以保證系統(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一定的比例)。⑶順序閥:能使一個執(zhí)行元件(如液壓缸﹑液壓馬達等)動作以后,再按順序使其他執(zhí)行元件動作。油泵產(chǎn)生的壓力先推動液壓缸1運動,同時通過順序閥的進油口作用在面積A 上,當液壓缸1運動完全成后,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,閥芯上升使進油口與出油口相通,使液壓缸2運動。

定壓溢流作用:在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中,定量泵提供的是恒定流量。當系統(tǒng)壓力增大時,會使流量需求減小。此時溢流閥開啟,使多余流量溢回油箱,保證溢流閥進口壓力,即泵出口壓力恒定(閥口常隨壓力波動開啟)。
穩(wěn)壓作用:溢流閥串聯(lián)在回油路上,溢流閥產(chǎn)生背壓,運動部件平穩(wěn)性增加。
系統(tǒng)卸荷作用:在溢流閥的遙控口串接溢小流量的電磁閥,當電磁鐵通電時,溢流閥的遙控口通油箱,此時液壓泵卸荷。溢流閥此時作為卸荷閥使用。
安全保護作用:系統(tǒng)正常工作時,閥門關閉。只有負載超過規(guī)定的極限(系統(tǒng)壓力超過調(diào)定壓力)時開啟溢流,進行過載保護,使系統(tǒng)壓力不再增加(通常使溢流閥的調(diào)定壓力比系統(tǒng)最高工作壓力高10%~20%)。
實際應用中一般有:作卸荷閥用,作遠程調(diào)壓閥,作高低壓多級控制閥,作順序閥,用于產(chǎn)生背壓(串在回油路上)。
溢流閥一般有兩種結(jié)構(gòu):1、直動型溢流閥 。2、先導式溢流閥。
對溢流閥的主要要求:調(diào)壓范圍大,調(diào)壓偏差小,壓力振擺小,動作靈敏,過載能力大,噪聲小。

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)生的局部阻力對流量進行調(diào)節(jié),從而控制執(zhí)行元件的運動速度。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動均勻性要求不高的執(zhí)行元件的運動速度基本上保持穩(wěn)定。⑵調(diào)速閥:在載荷壓力變化時能保持節(jié)流閥的進出口壓差為定值。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)行元件的運動速度穩(wěn)定。⑶分流閥:不論載荷大小,能使同一油源的兩個執(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。
1)動作靈活,作用可靠,工作時沖擊和振動小,噪聲小,使用壽命長。
2)流體通過液壓閥時,壓力損失?。婚y口關閉時,密封性能好,內(nèi)泄漏小,無外泄漏。
3)所控制的參量(壓力或流量)穩(wěn)定,受外部干擾時變化量小。
4)結(jié)構(gòu)緊湊,安裝、調(diào)試、使用、維護方便,通用性好[2] 。
