Adjustable pressure valve and excavator hydraulic oil return system
The invention relates to the technical field of hydraulic systems, and particularly discloses an adjustable pressure valve and an excavator hydraulic oil return system.The adjustable pressure valve comprises a valve body, a valve set and an adjusting assembly, and a branch liquid inlet hole and a liquid outlet hole which is opposite to and communicated with the peripheral wall of the branch liquid inlet hole are formed in the valve body; the valve group comprises a first valve core and an elastic piece, the first valve core is in sliding fit with the branch liquid inlet hole, so that the first valve core has a first position for closing one end of the branch liquid inlet hole and the liquid outlet hole and a second position for communicating the end of the branch liquid inlet hole and the liquid outlet hole, and the elastic piece drives the first valve core to have a movement trend from the second position to the first position; the adjusting assembly is arranged at the other end of the branch liquid inlet hole, the elastic piece abuts against the first valve element and the adjusting assembly, and the adjusting assembly adjusts the distance between the first valve element and the adjusting assembly when the first valve element is located at the first position. According to the adjustable pressure valve, the opening pressure of the valve can be adjusted. Therefore, the energy loss in the system is reduced.
本发明涉及液压系统技术领域，具体公开了可调压力阀及挖掘机液压回油系统，该可调压力阀包括阀体、阀组和调节组件，阀体内设置有支进液孔和与支进液孔的周壁相对且连通的出液孔；阀组包括第一阀芯和弹性件，第一阀芯与支进液孔滑动配合，以使第一阀芯具有使支进液孔的一端和出液孔封闭的第一位置和连通的第二位置，弹性件驱动第一阀芯具有由第二位置至第一位置的运动趋势；调节组件设置于支进液孔的另一端，弹性件分别与第一阀芯和调节组件抵接，调节组件调节第一阀芯位于第一位置时与调节组件的间距。该可调压力阀能实现阀开启压力的调节。以降低系统中能量的损耗。
