In above-mentioned two breather valves, the shape of valve opening is identical with valve block shape: a valve opening front shape is that normal cone platform shape, cross section are that trapezoidal, supporting valve block is also that normal cone platform shape, cross section are trapezoidal; Another valve block front shape is that rounding taper type, cross section are inverted trapezoidal, and valve opening is also that rounding taper type, cross section are also inverted trapezoidal, forms sealing system; Above-mentioned valve block front shape is a large rectangle and a little rectangular combination; In the time that drying receptacle external and internal pressure is consistent, by the stretching of spring and the constraint of valve opening, two valve blocks are all packed in supporting valve opening, play the effect that stops gas flow.
Using method and the principle of vacuum drying container of the present invention are: material dry need is put into drying receptacle, build upper cover. Valve block, in the time that container external and internal pressure is identical, keeps closing because the pulling force effect of spring makes valve opening, has the performance that stops gas flow, avoids material wherein to contact with air. In the time that vacuum drying container is put into vacuum drying chamber and vacuumized, because container inner pressure is greater than outside container, under differential pressure action, the up big and down small valve block of diameter, along axle of spring to container outer displacement, makes to produce gap between valve block and valve opening, realizes gas in container and extracts out; Otherwise when vacuum drying chamber is during in vacuum state inert gas injecting, because container inner pressure is less than outside container, under diameter, large little valve block, to container intrinsic displacement under differential pressure action, is realized inert gas and is injected container. When container external and internal pressure is consistent, valve block under the stretching action of spring automatically in closed condition; When container is taken out to vacuum drying chamber, because valve block is in horizontal closed condition, thereby avoids the exchange of outside air and gas in container and prevent the material moisture absorption or oxidation again.
