經(jīng)銷REXROTH力士樂(lè)壓力調(diào)節(jié)閥R412010570
REXROTH方向座閥直動(dòng)式方向閥是通過(guò)啟閉件的節(jié)流,
將進(jìn)口壓力減至某一需要的出口壓力,并使
及原理上的區(qū)別反沖式又可分為:膜片式反沖電磁閥
活塞式反沖電磁閥;導(dǎo)式又可分為:導(dǎo)式膜片電磁閥、
處于關(guān)閉狀態(tài),使用時(shí)按順時(shí)針轉(zhuǎn)動(dòng)調(diào)節(jié)螺釘,壓縮調(diào)節(jié)彈簧
使膜瓣移頂開(kāi)付閥瓣,介質(zhì)由a孔通過(guò)付閥座到b孔進(jìn)入活塞上方
,活塞在介質(zhì)壓力的作用下,向下移動(dòng)推動(dòng)主閥瓣離開(kāi)主閥座,

它緊扣在閥座上。閥瓣上面是加載機(jī)構(gòu),載荷的大小可以調(diào)節(jié)。
It is closely linked to the valve seat. The above is
