DBW30AG-2-30/31.5G24NZ4 作用在主閥芯6上下兩個(gè)方向的壓力相等,但因上端面的有效受壓面積A2大于下端面的有效受壓面積A1,主閥芯在合力的作用下處于最下端位置,閥口關(guān)閉。當(dāng)進(jìn)油壓力增大到使先導(dǎo)閥打開時(shí),液流通過主閥芯上的阻尼孔5、先導(dǎo)閥1流回油箱。由于阻尼孔的阻尼作用,使主閥芯6所受到的上下兩個(gè)方向的液壓力不相等,主閥芯在壓差的作用下上移,打開閥口,實(shí)現(xiàn)溢流,并維持壓力基本穩(wěn)定。調(diào)節(jié)先導(dǎo)閥的調(diào)壓彈簧9,便可調(diào)整溢流壓力。 |
