Pressure limiting valve of pressure cooker

Abstract

The pressure limiting valve of the pressure cooker relates to the technical field of pressure limiting valve structures and comprises a base cylinder, a limiting flange ring is installed on the outer side wall, close to the bottom end, of the base cylinder, a bearing box is installed at the bottom end of the base cylinder through a multidirectional rotating mechanism, and an opening of the bearing box corresponds to the bottom end of the base cylinder; a threaded structure is arranged on the outer side wall of the base cylinder, a fixing ring is installed on the threaded structure in a threaded connection mode, and an outer cover is installed on the top side of the fixing ring through a plurality of connecting rods. High-pressure gas pushes the pressure head to slide upwards along the outer cover through the base cylinder, so that the pressure head is separated from the base cylinder, the flow direction of the high-pressure gas is changed through blocking of the flange piece, the high-pressure gas is sprayed out through the gap of the connecting rod in the horizontal direction, the flowing path of the gas is reduced, the contact area with the pressure limiting valve is reduced, and the pollution surface is reduced; and if a small amount of sundries fall from the base cylinder, the sundries can directly fall into the receiving box below the base cylinder, so that the food in the pot is further prevented from being polluted.

Description

technical field [0001] The invention relates to the technical field of pressure limiting valve structures, in particular to a pressure limiting valve for pressure cookers. Background technique [0002] A pressure cooker is a type of pot that increases the physical phenomenon of the boiling point of a liquid at a higher air pressure and applies pressure to the water so that the water can reach a higher temperature without boiling, in order to speed up the efficiency of stewing food, during the cooking process , When the pressure in the pressure cooker reaches the working pressure, the pressure limiting valve works through the exhaust hole to exhaust the air to keep the pressure in the pot within a certain range to achieve the purpose of safe cooking. [0003] In the prior art, the pressure limiting valve is mostly of the hammer type or the spring type. Generally, a vent hole is opened at the top of the valve to discharge pressure. Due to the small size of the vent hole, it is...

AI Technical Summary

Problems solved by technology

[0004] The purpose of this application is to provide a pressure-limiting valve for a pressure cooker to solve the problem that the inside of the pressure-limiting valve is not easy to clean, adhered to the wall of the vent hole, and the deteriorated substance will fall into the pot, causing food contamination.
