KRACHT SPVF40A2F1A12溢流閥直動式、滑動活塞式溢流閥主要由閥(fa)體(ti)、閥(fa)芯、調壓彈(dan)簧和調壓螺釘(或(huo)稱手柄)組成。在(zai)常態下,閥(fa)芯在(zai)調壓彈(dan)簧的作用下緊貼在(zai)閥(fa)座上,進油(you)(you)口(kou)P和出油(you)(you)口(kou)T 是不通的(即溢流(liu)閥(fa)為(wei)常閉型)。 閥的構造: 滑動(dong)活塞(sai)2在壓(ya)(ya)(ya)縮彈(dan)簧(huang)3作(zuo)(zuo)用下壓(ya)(ya)(ya)在環形區域a上。因此與泵想(xiang)通的P口同(tong)與油(you)箱相通的R口被(bei)直徑(jing)d處(chu)的密封隔離開。一旦工(gong)作(zuo)(zuo)壓(ya)(ya)(ya)力(li)達到由(you)調(diao)節螺釘4調(diao)定(ding)的壓(ya)(ya)(ya)力(li),滑動(dong)活塞(sai)2開始卸荷液壓(ya)(ya)(ya)油(you)至油(you)箱。彈(dan)簧(huang)腔(qiang)b由(you)孔c進行壓(ya)(ya)(ya)力(li)補償。開始時,彈(dan)簧(huang)腔(qiang)b一定(ding)要通過放氣(qi)孔5(六角螺釘)進行排氣(qi)。 閥(fa)盡量(liang)垂直(zhi)安裝,使壓力調(diao)定量(liang)垂直(zhi)向(xiang)下。 該溢流閥(fa)有(you)4種(zhong)壓(ya)力調節范圍,這(zhe)是(shi)因為彈(dan)(dan)簧的(de)壓(ya)縮(suo)比決定了每種(zhong)彈(dan)(dan)簧只能覆(fu)蓋有(you)限的(de)壓(ya)力調節范圍。 KRACHT SPVF40A2F1A12溢流閥規格參數: 結構:直動式,滑動活塞式溢流閥 連接:管式連接 管連接規格:SAE法蘭3000psi 惠氏管螺紋G 安裝方向:調節螺釘垂直向下 殼體材料:G630(GJS-400] 壓力設定方式:螺釘、旋鈕 附件:焊接式法蘭接頭SAE(3000psi 液壓油:液壓油DIN 51524/25 KRACHT SPVF40A2F1A12溢流閥德國原廠訂貨,品質超好,使用安全更放心,采購訂貨就認準“上海維特銳”,公司供應KRACHT全系列泵、閥、流量計等產品,價格公道,貨期靠譜,確保您交貨無憂!
