產品概覽:

按用(yong)途分(fen)(fen)為(wei)單(dan)向(xiang)閥(fa)(fa)和換向(xiang)閥(fa)(fa)。單(dan)向(xiang)閥(fa)(fa):只允許(xu)流體在管(guan)道中(zhong)單(dan)向(xiang)接通(tong)(tong)(tong)，反向(xiang)即切斷。換向(xiang)閥(fa)(fa):改(gai)變(bian)不同管(guan)路間(jian)的(de)(de)通(tong)(tong)(tong)、斷關(guan)系。根(gen)據閥(fa)(fa)芯(xin)(xin)在閥(fa)(fa)體中(zhong)的(de)(de)工作位(wei)(wei)置數分(fen)(fen)兩(liang)位(wei)(wei)、三(san)位(wei)(wei)等;根(gen)據所控制(zhi)的(de)(de)通(tong)(tong)(tong)道數分(fen)(fen)兩(liang)通(tong)(tong)(tong)、三(san)通(tong)(tong)(tong)、四(si)通(tong)(tong)(tong)、五(wu)通(tong)(tong)(tong)等;根(gen)據閥(fa)(fa)芯(xin)(xin)驅動(dong)方式分(fen)(fen)手動(dong)，機動(dong)，電動(dong)，液動(dong)等。圖2為(wei)三(san)位(wei)(wei)四(si)通(tong)(tong)(tong)換向(xiang)閥(fa)(fa)的(de)(de)工作原理。P 為(wei)供油(you)口(kou)(kou)，O 為(wei)回油(you)口(kou)(kou)，A 、B 是通(tong)(tong)(tong)向(xiang)執(zhi)行(xing)(xing)元(yuan)件(jian)的(de)(de)輸出(chu)口(kou)(kou)。當閥(fa)(fa)芯(xin)(xin)處於(wu)中(zhong)位(wei)(wei)時，全部油(you)口(kou)(kou)切斷，執(zhi)行(xing)(xing)元(yuan)件(jian)不動(dong);當閥(fa)(fa)芯(xin)(xin)移(yi)到(dao)右(you)位(wei)(wei)時，P 與(yu)A 通(tong)(tong)(tong)，B 與(yu)O 通(tong)(tong)(tong);當閥(fa)(fa)芯(xin)(xin)移(yi)到(dao)左位(wei)(wei)時，P 與(yu)B 通(tong)(tong)(tong)，A 與(yu)O 通(tong)(tong)(tong)。這樣，執(zhi)行(xing)(xing)元(yuan)件(jian)就(jiu)能(neng)作正、反向(xiang)運(yun)動(dong)。

按用途(tu)分為溢(yi)(yi)流(liu)閥(fa)(fa)﹑減(jian)壓(ya)(ya)閥(fa)(fa)和(he)順(shun)(shun)序閥(fa)(fa)。⑴溢(yi)(yi)流(liu)閥(fa)(fa):能(neng)(neng)控制(zhi)(zhi)液(ye)壓(ya)(ya)系統在達到(dao)調定(ding)(ding)壓(ya)(ya)力(li)時(shi)保(bao)持(chi)(chi)恒定(ding)(ding)狀(zhuang)態。用於過載保(bao)護的(de)(de)溢(yi)(yi)流(liu)閥(fa)(fa)稱為安(an)全(quan)閥(fa)(fa)。當(dang)系統發生故(gu)障，壓(ya)(ya)力(li)升(sheng)高到(dao)可(ke)能(neng)(neng)造成(cheng)破壞的(de)(de)限定(ding)(ding)值(zhi)時(shi)，閥(fa)(fa)口(kou)會打開(kai)而溢(yi)(yi)流(liu)，以保(bao)證系統的(de)(de)安(an)全(quan)。⑵減(jian)壓(ya)(ya)閥(fa)(fa):能(neng)(neng)控制(zhi)(zhi)分支(zhi)回(hui)(hui)路得(de)到(dao)比(bi)主回(hui)(hui)路油(you)(you)(you)(you)壓(ya)(ya)低的(de)(de)穩定(ding)(ding)壓(ya)(ya)力(li)。減(jian)壓(ya)(ya)閥(fa)(fa)按它(ta)所控制(zhi)(zhi)的(de)(de)壓(ya)(ya)力(li)功能(neng)(neng)不同(tong)，又可(ke)分為定(ding)(ding)值(zhi)減(jian)壓(ya)(ya)閥(fa)(fa)(輸出(chu)壓(ya)(ya)力(li)為恒定(ding)(ding)值(zhi))﹑定(ding)(ding)差減(jian)壓(ya)(ya)閥(fa)(fa)(輸入與輸出(chu)壓(ya)(ya)力(li)差為定(ding)(ding)值(zhi))和(he)定(ding)(ding)比(bi)減(jian)壓(ya)(ya)閥(fa)(fa)(輸入與輸出(chu)壓(ya)(ya)力(li)間(jian)保(bao)持(chi)(chi)一(yi)定(ding)(ding)的(de)(de)比(bi)例)。⑶順(shun)(shun)序閥(fa)(fa):能(neng)(neng)使一(yi)個(ge)執行元件(jian)(如液(ye)壓(ya)(ya)缸(gang)﹑液(ye)壓(ya)(ya)馬達等)動(dong)作以后(hou)，再按順(shun)(shun)序使其他(ta)執行元件(jian)動(dong)作。油(you)(you)(you)(you)泵產生的(de)(de)壓(ya)(ya)力(li)先推(tui)動(dong)液(ye)壓(ya)(ya)缸(gang)1運動(dong)，同(tong)時(shi)通過順(shun)(shun)序閥(fa)(fa)的(de)(de)進油(you)(you)(you)(you)口(kou)作用在面積(ji)A 上(shang)，當(dang)液(ye)壓(ya)(ya)缸(gang)1運動(dong)成(cheng)后(hou)，壓(ya)(ya)力(li)升(sheng)高，作用在面積(ji)A 的(de)(de)向上(shang)推(tui)力(li)大於彈簧(huang)的(de)(de)調定(ding)(ding)值(zhi)后(hou)，閥(fa)(fa)芯上(shang)升(sheng)使進油(you)(you)(you)(you)口(kou)與出(chu)油(you)(you)(you)(you)口(kou)相通，使液(ye)壓(ya)(ya)缸(gang)2運動(dong)。

液壓閥是一種用壓力(li)油操作的(de)自動化元件，它受配壓閥壓力(li)油的(de)控(kong)制，通常(chang)與電磁配壓閥組(zu)合使用，可用于遠(yuan)距離控(kong)制水電站油、氣(qi)、水管路系統的(de)通斷。常(chang)用于夾緊、控(kong)制、潤滑等油路。有直動型與先導(dao)型之分(fen)，多用先導(dao)型。
