Abstract
A two-purpose safety valve for pressure cooker features that it can be used for both over-heat and over-pressure as an easily fusable material is arranged at internal end of said valve to prevent too high temp inside the cooker. Said easily fusable material is fixed by a blocking piece made of the same material as the main body of said cooker, so preventing the pollution of said easily fusable material to the food in cooker.
Description
Technical field
The present invention is the dual-purpose safe valve of the safety valve of pressure cooker in the cooker, particularly a kind of pressure cooker.
Background technology
Quick-fried pot takes place to boiling dry pot in prior art, safe practice is arranged, but go back imperfection.
Summary of the invention
Technical problem to be solved by this invention is that a kind of further dual-purpose safe valve of the perfect overheated pressure cooker of overvoltage is provided.
The technical solution adopted in the present invention is: in the pot of valve one with its diameter made from the same material of pot less than valve body have the fusible material place internal diameter and greater than one can the going up to avoid the fusible material erosion drop on a jam in the pot the hole is stifled of aperture in the pot of valve, alleged dual-purpose valve is the pressure in pot when being raised to safe pressure, heats up and pressure release or boil dry pot and be raised to the fusing point of fusible material and pressure release in the normal pressure body temperature of cooking owing to boost.
Such valve has just had the overheated function that all works of overvoltage, and in the pot of this valve one have a bit flat drum not have hard angle to rinse slightly to wash conveniently, have simultaneously and the jam of the same material of pot, fusible material can not pollute in the pot.
Description of drawings
Fig. 1 cutaway view of the present invention.
The specific embodiment
As shown in the figure, it has illustrated pot cover 1, pot body 2, the sectional elevation relation of the locknut 6 of dual-purpose valve 3 jams 4 fusible materials 5 dual-purpose valves.In the pot of valve one with its diameter made from the same material of pot less than valve body have the fusible material place internal diameter and greater than one can the going up to avoid the fusible material erosion drop on a jam in the pot the hole is stifled of aperture in the pot of valve, alleged dual-purpose valve is the pressure in pot when being raised to safe pressure, heats up and pressure release or boil dry pot and be raised to the fusing point of fusible material and pressure release in the normal pressure body temperature of cooking owing to boost.
Claims (1)
1. the dual-purpose safe valve of a pressure cooker, it is characterized in that: dual-purpose valve (3) is to be contained on pot body (2), and one has jam (4) in the pot of valve, and one in the pot of valve has a bit flat drum not have hard angle slightly.
