The utility model discloses a hydraulic air cylinder braking angle type mud valve which comprises a hydraulic oil cylinder. The hydraulic oil cylinder is fixedly installed on the angle type mud valve. Guide grooves are formed in a wall of the hydraulic oil cylinder. Sliding feet are arranged on a piston edge in the oil cylinder and are matched with the guide grooves in a sliding mode. A piston rod is fixedly connected with a piston and penetrates and contacts the wall of the angle type mud valve in the sliding mode. A rubber ring is fixedly arranged on the middle portion of the wall of the angle type mud valve and is sleeved on the piston rod. The end portion of the piston rod is connected with a valve plate. Rubber is coated on the valve plate. The valve plate is connected with a guide cylinder. A reverse lug is arranged on the end portion of the piston rod and is connected with the guide cylinder is the sliding mode. A spring is arranged between an end face of the piston rod and the valve plate. The end face of the piston rod is in elastic connection with the valve plate. Hydraulic pressure or pneumatic force is used as a starting force so that opening speed is fast, resistance coefficient is small, opening and closing time is short, sealing performance reliability is good, the rubber ring plays a role of protecting the angle type mud valve and a hole penetrating through the piston rod is preventing from becoming bigger
