Abstract

The invention discloses a pressure release valve used for a pressure cooker and the pressure cooker. The pressure release valve comprises a valve seat and a valve element. The valve element comprises a sealing part and a valve rod connected with the sealing part. A step passageway penetrating through the two opposite ends of the valve seat is arranged on the valve seat. A first step and a second step are arranged in the step passageway. Exhaust holes communicated with the step passageway are formed in the portion, between the first step and the second step, of the valve seat. The pressure release valve further comprises an elastic reset piece and an elastic sealing body. A valve rod is sleeved with the elastic reset piece. The two opposite ends of the elastic reset piece can elastically abut against the valve rod and the first step respectively. The elastic sealing body is arranged on the second step and arranged on the valve rod in a sleeving mode. A through hole for the valve rod to penetrate through is formed in the elastic sealing body. The sealing part abuts against the bottom face of the elastic sealing body and seals the through hole. The sealing part is pushed by pressure to penetrate through the through hole and move to the space between the first step and the second step. Rapid and stable exhausting can be achieved; meanwhile, the two-stage pressure release function is achieved, and it is ensured that use of the pressure cooker is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of pressure cookers, in particular to a pressure relief valve for a pressure cooker and a pressure cooker. Background technique [0002] On the lid of the pressure cooker, in addition to the pressure limiting valve, some safety devices are also provided to prevent explosion accidents from occurring after the pressure limiting valve is blocked. These safety devices are usually pressure relief valves. After the pressure limiting valve is blocked, the high pressure in the pressure cooker will make the pressure relief valve in a pressure relief state, and the gas will be discharged from the pressure relief valve. At present, the pressure relief valve used in the pressure cooker is the skylight pressure relief mechanism. When the pressure in the pressure cooker exceeds a certain value, the skylight pressure relief mechanism will quickly release the gas in the pot. During the pressure relief process, the sealing r...
