Abstract
The invention discloses an upper cover of an air-brake brake valve, which comprises an upper cover shell and an upper cover brake piston. The upper cover brake piston is in sliding sealed fit with the inner wall of a piston cavity of the upper cover shell. A brake chamber is formed by the top face of the upper cover brake piston and that of the piston cavity. Control air holes are reserved on the upper cover shell. A guide column is disposed on the upper portion of the upper cover brake piston. A guide channel which is matched with the guide column is disposed on a top cover of the upper cover shell. Big-end-up vertical three-stepped holes are reserved in the center of the upper cover brake piston. The control holes are communicated with the biggest stepped hole. The lower end of the biggest stepped hole is lower than the top face of the upper cover brake piston. A small piston is disposed in the biggest stepped hole and a spring supporting the small piston is disposed in the middle stepped hole. The top face of the upper cover brake piston is a conical face with higher outer side and lower inner side. A drainage hole leads to the biggest stepped hole is reserved on the guide column. The brake chamber has no waterlogging, so that freezing jam in winter can be avoided.
