kracht克拉克溢流閥,SPV/SPVF是直動(dòng)式,滑動(dòng)活塞式溢流閥。連接于管路中,對(duì)低壓液壓回路的壓力進(jìn)行限定。最高壓力為20(30)bar.連接口可以是SAE(3000psi)法蘭口,也可以是惠氏管螺紋口。
kracht克拉克SPV/SPVF直動(dòng)式閥的結(jié)構(gòu)
滑動(dòng)活塞2在壓縮彈簧3作用下壓在環(huán)形區(qū)域a上。因此與泵想通的p口同與油箱相通的R口被直徑D處的密封隔離開。一旦工作壓力達(dá)到由調(diào)節(jié)螺釘4調(diào)定的壓力,滑動(dòng)活塞2開始卸荷液壓油至油箱。彈簧腔b由孔c進(jìn)行壓力補(bǔ)償。開始時(shí)彈簧腔b一定要通過放氣孔5(六角螺釘)進(jìn)行排氣。閥最好是垂直安裝,使壓力調(diào)定量垂直向下。該溢流閥有4種壓力調(diào)節(jié)范圍,這是因?yàn)閺椈傻膲嚎s比決定了每種彈簧只能覆蓋有限的壓力調(diào)節(jié)范圍。
