济南液压升降机用于货物和人员运送,为了货物,设备,人员安全,公司对济南液压升降机产品采购安装了防裂阀,产品使用过程中,当设备台面在高处时出现问题,确保液压升降机不会出现快速下降失控事故,而控制台面缓慢下降。
Ji'nan hydraulic lifts for goods and personnel transport, in order to goods, equipment, personnel safety, the company installed a crack resistant valve of Ji'nan hydraulic elevator product procurement, product use process, when the equipment table problems on high, to ensure that the hydraulic lift will not appear quickly fell out of control accident, while the control table decreased slowly.

防裂阀用于重载液压式升降机的安全防裂阀,由阀体、压簧、滑阀和挡圈组成,阀体的腔体内设有压簧,压簧与一可在腔体内滑动的滑阀连接,滑阀由嵌在阀体内的挡圈限位,滑阀的顶部设有通孔,滑阀的底部为堵头,腔体与阀体的进、出口连通。
Crack resistant valve used for security crack resistant valve heavy-duty hydraulic elevator, comprising a valve body, a pressure spring, a slide valve and a retaining ring, a valve body cavity is provided with a pressure spring, a pressure spring is connected with the slide valve which can slide in the cavity, valve by the block ring in the valve body spool limit, the top is provided with a through hole, slide valve at the bottom of the cavity and the valve plug, inlet, outlet.

紧靠油缸的近油口(也做出油口)处装有防裂阀,当液压管路发生破裂时,堵头封住阀体的进口,切断了油缸的外泄油流,以防止油管突然破裂发生下降失控事故。
Recent oil close to the cylinder mouth (also make the oil outlet is arranged at the position where the crack resistant valve), when the hydraulic pipeline rupture, import plug seal valve body, cut off the leakage of oil cylinder flow, in order to prevent the oil pipe rupture suddenly happened to drop out of control accident.

一旦油管破裂,造成升降平台下降速度过快时,防裂阀快速关闭,成节流状态,使济南液压升降机台面缓慢下降,保障人身和设备的安全,从而起到了安全作用。
