Gravity-type pressure-regulating and pressuring-limiting valve

Abstract

The invention provides a gravity-type pressure-regulating and pressuring-limiting valve, belonging to the technical field of cooking utensils, and solving the problems that the existing pressure cooker pressure-limiting valve has complex whole structure, high manufacturing cost, inconvenient operation and incapability of indicating the state of regulating pressure. The gravity-type pressure-regulating and pressuring-limiting valve is arranged at the position of an exhaust pipe of a pressure pot cover and comprises a cylindrical valve seat which is fixed on the cooker cover and is positioned at the periphery of the exhaust pipe; the valve seat is internally provided with a valve body which is sheathed at the periphery of the exhaust pipe; the top part of the valve body is fixed with a valve cap which has a tip which can be buckled on the exhaust pipe, and is provided with an exhaust orifice; the valve body is provided with a weight body which can be hung on the valve body and can separate from the valve body or jack up the valve body when rising axially; the weight body and the valve seat are positioned circumferentially; the valve seat is internally provided with a pressure-regulating sleeve capable of rotating circumferentially; and a pressure-regulating structure which can drive the weight body to rise and fall when the pressure-regulating sleeve rotates is arranged between the pressure-regulating sleeve and the weight body. The gravity-type pressure-regulating and pressuring-limiting valve has the advantages of convenient pressure regulation and stable working performance and the like.

Description

technical field [0001] The invention belongs to the technical field of cooking utensils, and relates to a pressure cooker, in particular to a gravity-type pressure regulating and limiting valve. Background technique [0002] A pressure cooker is a common kitchen appliance. In order to make the pot reach a certain air pressure, and when the air pressure in the pot exceeds the set air pressure range, it can exhaust outwards, and a pressure limiting valve is set on the pot cover. Existing pressure limiting valve realizes its pressure limiting function by being pressed on the exhaust pipe of the pressure cooker cover by its own weight. However, the pressure required in the pot will vary when cooking various foods. At this time, the usual method is to superimpose a heavy hammer on the pressure limiting valve, and increase the weight through the heavy hammer, so that the pot can reach a higher pressure. Although this method is feasible, the operation is more troublesome. Simul...

Problems solved by technology

[0004] The above-mentioned solution solves the problems existing in the prior art to a certain extent, but there are still deficiencies: 1. The overall structure is relatively complicated, the manufacturing cost is high, and it is prone to damage after long-term use, and its pressure regulating performance decreases with the decrease of spring performance. reduce

2. The operation is not convenient enough to indicate the state of pressure regulation, causing inconvenience to users
