The lifting locking control valve set comprises an installation valve block, and a filter, a proportional reversing valve, an overflow valve, a stop valve, a one-way valve, a speed regulating valve, an electromagnetic reversing valve, an electromagnetic ball valve, a shuttle valve and other oil charging and discharging assemblies are installed on the installation valve block. An oil channel is formed in the mounting valve block, an oil inlet, an oil return opening and a working oil opening are formed in the outer surface of the mounting valve block, and a filter, a proportional reversing valve, an overflow valve, a stop valve, a one-way valve and an oil charging and discharging assembly are integrated on the mounting valve block, so that a connecting pipeline between valve groups is simplified, the integration degree is higher, and the structure is simpler; the filter filters hydraulic oil, the opening degree of the overflow valve is adjusted to achieve control over the highest pressure of a third oil port of the proportional reversing valve, and therefore pressure control over the valve set is achieved, the stop valve can achieve oil way locking of a working oil port and an oil return port, and the hydraulic oil is prevented from flowing out abnormally. The lifting locking control valve group integrates the functions of hydraulic oil filtering, pressure control and emergency cut-off, and is comprehensive in function and easy to operate.
本申请公开了一种升降闭锁控制阀组,包括一安装阀块,安装阀块上安装有过滤器、比例换向阀、溢流阀、截止阀、单向阀和调速阀、电磁换向阀、电磁球阀及梭阀等充放油组件;安装阀块内部开设有油道,安装阀块的外表面设置有进油口、回油口和工作油口,通过在安装阀块上集成过滤器、比例换向阀、溢流阀、截止阀、单向阀和充放油组件,简化了阀组之间的连接管路,集成度更高,结构更简单;过滤器过滤液压油,调节溢流阀的开度实现对比例换向阀第三油口最高压力的控制,从而实现对阀组的压力控制,截止阀可实现工作油口与回油口的油路闭锁,避免液压油异常流出,该升降闭锁控制阀组集成了液压油过滤、压力控制和应急截止功能,功能全面且操作简单。
