PARKER派克減壓閥工作原理：
PARKER減(jian)壓閥(fa)(fa)(fa)(fa)(fa)出廠時(shi)(shi)，調(diao)(diao)(diao)節(jie)彈簧處于(yu)(yu)未壓縮狀態,此(ci)時(shi)(shi)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)(fa)瓣(ban)(ban)(ban)(ban)(ban)(ban)和副閥(fa)(fa)(fa)(fa)(fa)瓣(ban)(ban)(ban)(ban)(ban)(ban)處于(yu)(yu)關閉狀態,使用(yong)時(shi)(shi)按順時(shi)(shi)針轉(zhuan)動(dong)(dong)調(diao)(diao)(diao)節(jie)螺釘,壓縮調(diao)(diao)(diao)節(jie)彈簧,使膜(mo)瓣(ban)(ban)(ban)(ban)(ban)(ban)移頂開付閥(fa)(fa)(fa)(fa)(fa)瓣(ban)(ban)(ban)(ban)(ban)(ban),介質(zhi)(zhi)由a孔(kong)通過(guo)付閥(fa)(fa)(fa)(fa)(fa)座到(dao)b孔(kong)進入活塞(sai)(sai)上(shang)(shang)方(fang),活塞(sai)(sai)在(zai)介質(zhi)(zhi)壓力(li)(li)(li)的(de)(de)作用(yong)下(xia),向(xiang)(xiang)下(xia)移動(dong)(dong)推動(dong)(dong)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)(fa)瓣(ban)(ban)(ban)(ban)(ban)(ban)離開主(zhu)(zhu)閥(fa)(fa)(fa)(fa)(fa)座,使介質(zhi)(zhi)流向(xiang)(xiang)閥(fa)(fa)(fa)(fa)(fa)后.同(tong)時(shi)(shi)由c孔(kong)進入膜(mo)片下(xia)方(fang),當(dang)閥(fa)(fa)(fa)(fa)(fa)后壓力(li)(li)(li)超過(guo)調(diao)(diao)(diao)定壓力(li)(li)(li)時(shi)(shi),推動(dong)(dong)膜(mo)片上(shang)(shang)移壓縮調(diao)(diao)(diao)節(jie)彈簧,付閥(fa)(fa)(fa)(fa)(fa)瓣(ban)(ban)(ban)(ban)(ban)(ban)隨(sui)之(zhi)向(xiang)(xiang)關閉方(fang)向(xiang)(xiang)移動(dong)(dong),使流入活塞(sai)(sai)上(shang)(shang)方(fang)的(de)(de)介質(zhi)(zhi)減(jian)小,壓力(li)(li)(li)也(ye)(ye)隨(sui)之(zhi)下(xia)降(jiang),此(ci)時(shi)(shi)的(de)(de)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)(fa)瓣(ban)(ban)(ban)(ban)(ban)(ban)在(zai)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)(fa)瓣(ban)(ban)(ban)(ban)(ban)(ban)彈簧力(li)(li)(li)的(de)(de)推動(dong)(dong)上(shang)(shang)下(xia)移,使主(zhu)(zhu)閥(fa)(fa)(fa)(fa)(fa)瓣(ban)(ban)(ban)(ban)(ban)(ban)與主(zhu)(zhu)閥(fa)(fa)(fa)(fa)(fa)座的(de)(de)間(jian)隙減(jian)小,介質(zhi)(zhi)流量也(ye)(ye)隨(sui)之(zhi)減(jian)小,使閥(fa)(fa)(fa)(fa)(fa)后壓力(li)(li)(li)也(ye)(ye)隨(sui)之(zhi)下(xia)降(jiang)到(dao)新的(de)(de)平衡,反之(zhi)當(dang)閥(fa)(fa)(fa)(fa)(fa)后壓力(li)(li)(li)低于(yu)(yu)調(diao)(diao)(diao)定壓力(li)(li)(li)時(shi)(shi),主(zhu)(zhu)閥(fa)(fa)(fa)(fa)(fa)瓣(ban)(ban)(ban)(ban)(ban)(ban)與主(zhu)(zhu)閥(fa)(fa)(fa)(fa)(fa)座的(de)(de)間(jian)隙增大,介質(zhi)(zhi)流量也(ye)(ye)隨(sui)之(zhi)增加,使閥(fa)(fa)(fa)(fa)(fa)后壓力(li)(li)(li)也(ye)(ye)隨(sui)之(zhi)增高(gao)達到(dao)新的(de)(de)平衡.
PARKER派克減壓(ya)閥(fa)(fa)然后依靠控制與調(diao)節(jie)(jie)系(xi)統(tong)的調(diao)節(jie)(jie)，使閥(fa)(fa)后壓(ya)力的波動(dong)與彈簧力相平衡(heng)，使閥(fa)(fa)后壓(ya)力在一定的誤差范圍內保持恒定。
parker減壓(ya)(ya)(ya)閥也分為直動式(shi)和先(xian)導式(shi)兩種，一(yi)般常用先(xian)導式(shi)parker減壓(ya)(ya)(ya)閥parker減壓(ya)(ya)(ya)閥。圖5-15(a)所示為先(xian)導式(shi)parker減壓(ya)(ya)(ya)閥的(de)結構(gou)口一(yi)次壓(ya)(ya)(ya)力油(you)p1由進油(you)口進人(ren)。
parker減壓(ya)閥(fa)(fa)經減壓(ya)口變為P2從出油口流出，P2同時(shi)經閥(fa)(fa)體6下(xia)部和端蓋(gai)8.上(shang)通(tong)道至主(zhu)閥(fa)(fa)芯(xin)7下(xia)腔，并通(tong)過(guo)主(zhu)閥(fa)(fa)芯(xin)上(shang)的(de)(de)阻尼(ni)孔9作用于先導閥(fa)(fa)3的(de)(de)右腔，然(ran)后(hou)通(tong)過(guo)錐閥(fa)(fa)座4的(de)(de)阻尼(ni)孔作用在錐閥(fa)(fa)上(shang)。
