Load-sensitive manual valve, hydraulic system and land leveler
The invention discloses a hydraulic valve, a hydraulic system and a land leveler, the hydraulic valve comprises a valve body, a plurality of flow channel sections, a main valve core and a through hole for receiving the main valve core are constructed in the valve body, the hydraulic valve further comprises a valve core stroke adjusting device, the valve core stroke adjusting device is arranged at the end part, extending out of the valve body, of the main valve core, the valve element stroke adjusting device comprises at least one valve element limiting element capable of adjusting the position in the axial direction of the main valve element, and the valve element limiting element is used for limiting the stroke of the main valve element in the axial direction. According to the scheme, the limiting element and the main valve element are evenly stressed in the limiting period, the structure is stable, limiting is reliable and accurate, reliability and durability are achieved, and installation and debugging are convenient. And meanwhile, the maintenance requirements of after-sales parts can be met in batches, so that the stock management cost of the maintenance parts is reduced. In addition, personalized modification requirements of customers can be met quickly.
本发明公开了一种液压阀、液压系统及平地机，该液压阀包括阀体，在阀体中构造有多个流道区段，主阀芯以及用于接纳主阀芯的通孔，其中，该液压阀还包括一阀芯行程调节装置，该阀芯行程调节装置设置在主阀芯伸出阀体的端部处，其中，该阀芯行程调节装置包括至少一个能在主阀芯的轴向方向进行位置调节的阀芯限位元件，用于在所述轴向方向上限定主阀芯的行程。根据本发明的方案，限位元件和主阀芯在限位期间受力均匀，结构稳定并且限位可靠精准，可靠耐用，便于安装调试。同时，能够批量覆盖售后件的维修需求，从而减少了维修部件的备货管理成本。另外，也能快速满足客户个性化改装需求。
