Rexroth博世力士樂比例伺服閥,德力士樂比例伺服閥原理
Rexroth博世力士樂比例伺服閥工作原理及結(jié)構(gòu)：減壓閥出廠時(shí)，調(diào)節(jié)彈簧處于未壓縮狀態(tài),此時(shí)主閥瓣和付閥瓣處于關(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,使膜瓣移頂開付閥瓣,介質(zhì)由a孔通過付閥座到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)主閥瓣離開主閥座,使介質(zhì)流向閥后.同時(shí)由c孔進(jìn)入膜片下方,當(dāng)閥后壓力超過調(diào)定壓力時(shí),推動(dòng)膜片上移壓縮調(diào)節(jié)彈簧,付閥瓣隨之向關(guān)閉方向移動(dòng),使流入活塞上方的介質(zhì)減小,壓力也隨之下降,此時(shí)的主閥瓣在主閥瓣彈簧力的推動(dòng)上下移,使主閥瓣與主閥座的間隙減小,介質(zhì)流量也隨之減小,使閥后壓力也隨之下降到新的平衡,反之當(dāng)閥后壓力低于調(diào)定壓力時(shí),主閥瓣與主閥座的間隙增大,介質(zhì)流量也隨之增加,使閥后壓力也隨之增高達(dá)到新的平衡.
