Abstract

The invention provides a pressure-limiting valve device and a pressure cooker; the pressure-limiting valve device comprises a valve body and a position assembly, wherein a first channel suitable for being communicated with the inner part of the pot body and a cavity communicated with the first channel are formed in the valve body; a second channel communicated with the cavity is formed in the valve body, and the outlet of the second channel is formed in the top surface of the valve body and faces upwards; the piston assembly is movably arranged in the cavity and has a first position enabling the first channel to be communicated with the second channel, and a second position enabling the first channel to be disconnected from the second channel; the piston assembly is arranged in the valve body and cannot be removed from the valve body; and due to the fact that the outlet of the second channel faces upwards, air cannot blow to a person, so that a user is not scalded easily.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a pressure limiting valve device and a pressure cooker. Background technique [0002] A spring-type multifunctional pressure-limiting valve is disclosed in the prior art, including a pressure-limiting valve body, a valve core, a nut, a spring, a sealing ring, and a nut. It is characterized in that the middle of the pressure-limiting valve body is a cylindrical hole, and its circumference The surface is provided with a pressure-holding hole, a lower vent hole, a first-stage vent hole, and a second-stage vent hole. The valve core is a cylindrical shaft, which is placed in the pressure-limiting valve body through a spring, and the upper end of the valve core is screwed together with the nut. On the body of the pressure limiting valve, there is a groove on the side of the cylinder at the lower end of the valve core, the nut is screwed and connected with the lower end of the ...
