    美國(guó)派克PARKER電磁閥中國(guó)一級(jí)代理
    美國(guó)Parker派克GFG系列2通調(diào)速閥處于關(guān)閉狀態(tài)時(shí)，系統(tǒng)壓力通過(guò)進(jìn)口壓力管、
    導(dǎo)閥和氣室壓力管傳到主閥閥瓣頂部的圓頂氣室，從而在主閥瓣上產(chǎn)生了一個(gè)向下的凈作用力，使主閥處于關(guān)閉狀態(tài)。
    當(dāng)系統(tǒng)壓力達(dá)到整定壓力時(shí)，導(dǎo)閥開(kāi)啟且滑梭封閉導(dǎo)閥進(jìn)氣通道，主閥氣室的壓力通過(guò)導(dǎo)閥排放卸壓，由于系統(tǒng)壓力高于回座壓力，
    滑梭封閉進(jìn)氣通道，從而隔斷流體在導(dǎo)閥中的流動(dòng)，這時(shí)主閥氣室的壓力急劇下降，主閥閥瓣*打開(kāi)，流體通過(guò)主閥泄放降壓。
    當(dāng)系統(tǒng)壓力降到一定值時(shí)，導(dǎo)閥的彈簧力克服了閥進(jìn)口壓力作用在滑梭上的力，導(dǎo)閥回座，頂桿頂開(kāi)滑梭，
    zui后使得流體重新進(jìn)入主閥的圓頂氣室，關(guān)閉主閥。我公司長(zhǎng)期經(jīng)營(yíng)出售美國(guó)派克PARKER液壓電磁閥，美國(guó)派克PARKER液壓泵
