Hydraulic valve bank, hydraulic control system and environmental sanitation motor sweeper
The invention discloses a hydraulic valve bank, a hydraulic control system and an environmental sanitation motor sweeper, and belongs to the technical field of environmental sanitation mechanical equipment. The hydraulic control valve comprises a valve body, and the valve body is provided with a coil used for driving a valve element and the valve element used for controlling the flow direction of oil. One end of the valve body is provided with an oil inlet module, and the other end of the valve body is provided with a tail link assembly; a P port of the oil inlet module is used for being connected with an oil supply port, and a T port of the oil inlet module is used for being connected with an oil return port. The motor sweeper adjusting system is suitable for a road sweeper and has load sensitive control, a load sensitive system adopting a three-way proportional flow valve and upstream pressure compensation is adopted, the electric proportional flow valve is located on a main oil inlet way, input current and valve element displacement of the proportional valve are in a direct proportion relation, and the flow is adjusted by changing the current; and under the interaction of the pressure compensation valve, the stable stepless regulation of the movement speed of the execution structure can be realized without being influenced by the load.
本发明公开了本发明公开一种液压阀组、液压控制系统及环卫清扫车,属于环卫机械设备技术领域。其包括阀体,所述阀体设有用于驱动阀芯的线圈及控制油液流向的阀芯;所述阀体的一端设有进油模块,另一端设有尾联组成;所述进油模块的P口用于连接供油口,所述进油模块的T口用于连接回油口;本发明适用于路面清扫车,具有负载敏感控制的清扫车调节系统,采用三通比例流量阀+阀前压力补偿的负载敏感系统,电比例流量阀位于主进油路上,输入电流与比例阀的阀芯位移成正比例关系,通过改变电流来调节流量大小,并且在压力补偿阀的相互作用下,可不受负载影响实现执行结构的运动速度平稳无级调节。
