The utility model relates to an engineering machinery hydraulic valve on-site inspection device, which is characterized by comprising a circuit block, an A port oil one-way valve, relief valve, A port, B port oil return one-way valve oil inlet one-way valve, B port oil return one-way valve and pressure; the output into the A port check valve and B port into the oil valve is communicated with the overflow valve input end; the output end of the overflow valve connected A port and B port oil return one-way valve oil return one-way valve; the overflow valve is located in the circuit block; the pressure measuring joint is provided with two, respectively in the oil block. By connecting the A and B ports of the hydraulic valve, the utility model causes the hydraulic oil to flow into the oil one-way valve or the B inlet oil inlet one-way valve through the A port on the oil block, then flows through the relief valve, and then flows out of the oil outlet check valve or the A outlet oil check valve from the B outlet. Adjust the handle of the overflow valve, observe the pressure gauge, detect the pressure of the hydraulic valve to reach the normal value, so as to determine whether the hydraulic valve and the hydraulic pump are in trouble.

一种工程机械液压阀现场检查装置
本技术涉及一种工程机械液压阀现场检查装置。
技术介绍
目前工程机械液压阀故障诊断都是由维修工程师在工地现场判断故障,由于液压故障判断难度高,相同的故障表现,很难排除是液压泵故障、液压阀故障还是液压马达故障。往往造成故障判断错误,将液压阀拆卸回工厂通过液压阀测试台检测没有问题,再来找其他故障原因,从而增加了维修成本,影响了用户设备工作时间。
技术实现思路
针对以上所述,本技术的目的在于解决上述问题的至少一个方面。为了实现本技术的目的所采用的技术方案是:一种工程机械液压阀现场检查装置,其特征在于:它包括油路块、A口进油单向阀、溢流阀、A口回油单向阀、B口进油单向阀、B口回油单向阀和测压接头;所述的A口进油单向阀和B口进油单向阀的输出端连通溢流阀的输入端;所述的溢流阀的输出端连通A口回油单向阀和B口回油单向阀;所述的溢流阀位于油路块上;所述的测压接头设有两个,分别位于路块上。进一步,所述的测压接头包括A口测压接头和B口测压接头。进一步,所述的A口测压接头连通A口进油单向阀的输入端和A口回油单向阀的输出端;所述的B口测压接头连通B口进油单向阀的输入端和B口回油单向阀的输出端。本技术的有益效果:通过连接液压阀的A、B口,使得液压油通过油路块上的A口进油单向阀或B口进油单向阀流入,流经溢流阀,然后从B口出油单向阀或A口出油单向阀流出。调节溢流阀的手柄,观察压力表,检测液压泵和液压阀输出压力能否达到正常值,从而判断出液压泵和液压阀是否故障。附图说明图1为本技术俯视图。图2为本技术整体结构示意图。图3为本技术液压原理图。图中。1-A口进油单向阀、2 ...
