Integrated hydraulic valve

The utility model relates to a hydraulic valve, in particular to an integrated hydraulic valve for braking a hydraulic motor, which comprises a valve body, a left valve seat, a right valve seat, a movable piston, a left one-way valve core, a right one-way valve core, a left plug, a right plug, a left one-way valve core spring, a right one-way valve core spring, an ejector rod, a left reset spring and a right reset spring. Compared with the prior art, the utility model can realize the control of quick starting and slow braking of mechanical braking. Meanwhile, control over mechanical braking is achieved through internal pressure of the hydraulic motor of the system, and compared with a conventional mode that control oil needs to be externally connected, the integration degree of the system is higher, and pipeline connection is simpler. 本实用新型涉及液压阀，尤其是涉及一种用于液压马达制动的一体式集成液压阀，包括阀体，左阀座，右阀座，移动活塞，左单向阀芯，右单向阀芯，左堵头，右堵头，左单向阀芯弹簧，右单向阀芯弹簧，顶杆，左复位弹簧，右复位弹簧。与现有技术相比，本实用新型可实现机械制动快速开启，慢速制动的控制。同时通过系统液压马达内部压力来实现机械制动的控制，与常规需要外接控制油相比，系
