The invention relates to the field of engineering machinery, and provides a brake valve, a brake system and an operation machine, comprising an air brake valve and a hydraulic brake valve. The hydraulic brake valve is arranged in an exhaust channel of the air brake valve, and the trigger end of the air brake valve and the trigger end of the hydraulic brake valve are both in transmission connection with the brake pedal. According to the brake valve, the hydraulic brake valve is arranged in the air brake valve, other space of a chassis of an operation machine is not occupied, the space of an exhaust channel is reasonably utilized, and when the brake pedal is treaded, due to the fact that the trigger ends of the air brake valve and the hydraulic brake valve are both in transmission connection with the brake pedal, the brake pedal is not damaged. The air brake valve and the hydraulic brake valve can be synchronously triggered, and the problem of how to synchronously trigger the air brake valve and the hydraulic brake valve is not needed to be considered.
本发明涉及工程机械领域,提供一种制动阀、制动系统和作业机械,包括气制动阀和液压制动阀。液压制动阀设置在气制动阀的排气通道内,且气制动阀与液压制动阀的触发端均与制动踏板传动连接。本发明提供的制动阀将液压制动阀设置在气制动阀内,不占用作业机械的底盘的其他空间,合理利用排气通道的空间,而且当踩下制动踏板时,由于气制动阀和液压制动阀的触发端均与制动踏板传动连接,因此,气制动阀和液压制动阀可实现被同步触发的效果,无需考虑气制动阀与液压制动阀如何同步被触发的问题。
