摘　　要：用KS2型快速移架系统装备ZFS6 2 0 0 / 18/ 35型支架 ,和支架原液压系统相比 ,KS2型系统移架速度快 ,其核心元件DHC大通道强开回液口操纵阀操作省力 ,旁路回液设计新颖、可靠。ZFS6200/18/35 type powered supports, equipped with the KS2 type fast support moving system, can be moved forward more quickly than that with the former hydraulic system The control valve with large passage and forced liquid return opening(DHC), which is the key component of the system, can be operated easily The by pass liquid return system is originally and reliably designed

关 键 词：DHC操纵阀 旁路回液 KS2型快速移架系统 支架 液压系统
