Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust pipes, and in particular relates to an easy-to-install exhaust pipe. Background Art

[0002] A pressure cooker is also called a pressure cooker or a pressure cooker. It is a kind of kitchen cooker. The pressure cooker uses the physical phenomenon that the boiling point of liquid increases under high pressure, so that water can reach a higher temperature without boiling, thereby speeding up the efficiency of stewing food. It can be used to heat the food to above 100℃. In high altitude areas, the use of a pressure cooker can avoid the problem of the water boiling point lowering and making it difficult to cook food. Its advantages are time saving and energy saving.

[0003] Whether it is a traditional gas pressure cooker or an electric pressure cooker, an exhaust valve is provided on the top of the lid. When in use, the exhaust valve cooperates with the exhaust port of the pressure cooker. The exhaust valve is used to limit the exhaust volume to maintain the required pressure in the pressure cooker. At the same time, it plays a role of pressure relief protection when the pressure in the pot is too high. The existing exhaust valve is generally fixed to the pot cover by tightening a nut. After being used for too long, it will become loose, resulting in leakage and the like. Utility Model Content
