The invention discloses a full-hydraulic two-way hydraulic control brake valve which comprises a valve body and a brake pedal. A valve cavity is formed in the valve body, and a first valve element and a second valve element are arranged in the valve cavity in a sleeved mode. Reset spring sets are arranged in valve cavities in the two ends of a core body formed by the first valve element and the second valve element, and under the action of the reset spring sets, the first valve element and the second valve element are located at the first position, so that the first brake oil port is communicated with the first oil return port, and the second brake oil port is communicated with the second oil return port. When the brake pedal is in a treading state, the first valve element and the second valve element move to a second position, so that the first brake oil port is communicated with the oil inlet, and the second brake oil port is communicated with the second oil inlet; the valve cavity further communicates with a hydraulic control port, the hydraulic control port communicates with high-pressure hydraulic oil, and the hydraulic control port can work independently of the brake pedal, overcome the acting force of the reset spring set and drive the first valve element and the second valve element to move from the first position to the second position. The device is reasonable in structure, good in use safety and capable of being remotely controlled.

    本发明公开了一种全液压双路液控制动阀,包括阀本体和制动踏板;阀本体内形成有阀腔,阀腔内套设有第一阀芯和第二阀芯;第一阀芯和第二阀芯所形成的芯体两端的阀腔内设有复位弹簧组,在复位弹簧组作用下,第一阀芯和第二阀芯处于第一位置,使第一制动油口与第一回油口连通、第二制动油口与第二回油口连通;当制动踏板处于踏下状态时,第一阀芯和第二阀芯位移至第二位置,使第一制动油口与进油口连通、且所述第二制动油口与第二进油口连通;阀腔还连通有液控口,液控口连通有高压液压油,且液控口可独立于所述制动踏板工作,克服复位弹簧组作用力,驱使第一阀芯和第二阀芯从第一位置位移至第二位置。本发明结构合理、使用安全性好且可远程操控。
