The invention discloses a metro passenger car fireless return ball valve locking device, relates to the field of vehicle brake system debugging, and solves the problems that in the prior art, when a brake ball valve is detected, due to short car detection time or improper operation of personnel, the position state of the ball valve is wrong, air charging of a train pipe is insufficient, and major safety accidents are caused due to the fact that braking cannot be exerted. The device comprises a base, a limiting groove, a fastening knob and a handle fastening part. The base is connected with a ball valve fixing part and is used for locking the ball valve locking device; the limiting groove is located in the middle of the fixing portion of the base and the ball valve handle and used for being connected with the fastening portion of the ball valve handle to limit and fix the ball valve handle. The handle fastening part is located at the top of the locking device and used for being connected with the ball valve fixing part. The fastening knob is used for fastening the ball valve locking device in place, it is guaranteed that the ball valve locking device is tightly connected with the ball valve, and the device is prevented from falling off due to vibration.
