The invention relates to the technical field of vehicle braking, and provides a hand brake valve control device and a hand brake valve. The operating device comprises a thrust block and a locking block, and the locking block is provided with a sliding face allowing the thrust block to move, a side wall protruding out of the sliding face and a locking groove located in the front end of the sliding face and allowing the thrust block to fall into. The transverse rod is movably erected on the side wall and located at the front end of the locking groove; the false locking prevention mechanism comprises a false locking prevention pin movably connected with the cross rod, and when the thrust block is located at the non-parking position, the false locking prevention pin shields the edge of the locking groove; when the thrust block moves to the parking position along the sliding face, the transverse rod is pushed to drive the anti-fake locking pin to make a falling path for the thrust block to fall into the locking groove. According to the operating device and the hand brake valve, through the false locking prevention mechanism, the false locking problem during parking braking can be effectively avoided, and the stability and safety of parking braking are improved.

    本发明涉及车辆制动技术领域,提供一种手制动阀操纵装置和手制动阀。操纵装置包括:止推块和锁止块,锁止块设置有供止推块运动的滑动面、突出于滑动面的侧壁、及位于滑动面的前端、供止推块落入的锁止槽;横杆,可活动地架设于侧壁、位于锁止槽的前端;防假锁止机构,包括可活动地连接横杆的防假锁止销,于止推块位于非驻车位置、防假锁止销遮挡锁止槽的边沿;随止推块沿滑动面运动至驻车位置,横杆被推动以带动防假锁止销让出供止推块落入锁止槽的落入路径。本发明的操纵装置和手制动阀,通过防假锁止机构,能够有效避免驻车制动时“假锁止”问题的发生,提高驻车制动的稳定性和安全性。
