Turning the upper part can raise up the conic needle from the exhaust hole of exhaust tube.

Description

Technical field [0001] The invention relates to a pressure limiting air release valve for a pressure cooker. The pressure cooker referred to in the present invention includes ordinary pressure cooker and automatic electric pressure cooker. Background technique: [0002] After the pressure cooker cooks, it takes a long time to reduce the pressure and open the lid. At present, the known heavy hammer type air release valve only has two grades of closing and opening. When cooking porridge or soup urgently needs to be opened, if the air release valve is removed, the porridge and soup will spray out, which is very inconvenient to use. Contents of the invention [0003] In order to overcome the deficiencies of the existing pressure-limiting air-releasing valve for pressure cookers, the present invention provides an adjustable pressure-limiting air-releasing valve, which not only has the safety function of general pressure-limiting air-releasing valve for overpressure air-releasi...
