Problems solved by technology

Although the pressure limiting valve can adjust the pressure in the pot, there are some problems. For example, the steel ball itself has weight, which cannot realize complete exhaust, and has potential safety hazards; The groove is unstable when sliding, and the pot will inevitably vibrate to varying degrees when it is in use, which will inevitably cause the two protrusions at the lower position of the pressure limiting knob to move in the inclined guide groove, thereby changing the maximum pressure in the pot, and It is not easy to adjust to a suitable pressure with this stepless adjustment method, which will inevitably bring inconvenience to users

Abstract

The invention discloses a spring type multi-gear pressure-limiting valve with the pressure adjustable and aims at achieving the effects that the spring type multi-gear pressure-limiting valve with the pressure adjustable is simple in structure, safe, stable and convenient to use and capable of satisfying various cooking requirements of consumers. The spring type multi-gear pressure-limiting valve comprises a valve seat (1), an exhaust pipe (2) and a pressure adjusting mechanism, the pressure adjusting mechanism comprises a lower valve element (3), an upper valve element (4), a rotary cover (5) and a pressure limiting spring (6), the lower valve element (3) is sleeved with the upper valve element (4) and provided with multiple valve element grippers, sliding grooves are formed in the inner wall of the upper valve element (4), multiple groups of step clamping positions are evenly distributed on the outer wall of the upper valve element (4), an inner ring seat is arranged on the valve seat (1), an air outlet of the exhaust pipe (2) is located inside the inner ring seat, and multiple valve seat clamping pillars are arranged on the inner wall of the inner ring seat. The spring type multi-gear pressure-limiting valve is applied to the technical field of pressure-limiting valves.

Description

technical field [0001] The invention relates to a pressure limiting valve, in particular to a spring-type multi-stage adjustable pressure limiting valve for cooking equipment. Background technique [0002] A pressure cooker is a device that uses pressure to increase the cooking temperature. One is a pressure cooker for heating with an open flame, and the other is an electric pressure cooker for heating with electric energy. It can be used to heat the food being steamed to above 100°C. With its unique high temperature and high pressure function, it greatly shortens the cooking time and saves energy. But the used pressure limiting valve of existing pressure cooker is the pressure limiting valve of a fixed weight, and the weight of pressure valve determines that pressure cooker is only a kind of pressure when working, and for different food, its cooking required pressure is also different. A single pressure is not conducive to cooking a variety of different foods, which is no...
