Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
As shown in Figs 1-4.Embodiment of the present invention is related to a kind of vacuum bag suspension push type air valve, including bottom valve 1 and upper
Lid 2, the bottom valve 1 is in the form of annular discs, and the upper end has been centrally located inner cavity 4, and the 2 activity insertion of upper cover is arranged in indent
In chamber 4, the bottom of the inner cavity 4 is equipped with the valve block 3 for covering gas vent 14, and the lower end of the gas vent 14 is placed in the middle
Be provided with positioning column 10, the valve block 3 include be centrally located in the gasket body 33 and 33 lower end of gasket body of umbrella shape it is embedding
Enter to the inserting column 31 in positioning column 10, the upper surface of the upper cover 2 is provided with aspirating hole 13 and interior central is provided with and valve
The support column 7 that piece 3 is in contact.
The upper end center of the gasket body 33 of the valve block 3 is provided with concave hole 32, and main purpose is for the production of valve block 3
After raw deformation, there are enough spaces that it is allowed to shrink.
The position of the inner sidewall of the inner cavity 4 on the lower is provided with a circle positioning groove 6, corresponding upper cover 2 it is outer
Side wall lower ends are provided with a circle positioning protrusion 8, can press upper cover 2 after the completion of pumping, on the outside of positioning protrusion 8 can be embedded in
Positioning is realized into positioning groove 6, it is easy to operate.
The inner sidewall top of the inner cavity 4 is provided with the retention bead 5 to match with positioning protrusion 8, when pumping
Upper cover 2 can up be mentioned, retention bead 5 can collide with positioning protrusion 8, and upper cover 2 is prevented to be detached from bottom valve 1.
The bottom of the bottom valve 1 is radioactive around gas vent 14 to be provided with several prominent muscle, and described is prominent
Muscle is made of the short prominent muscle 11 separately arranged and long prominent muscle 12 out, the inner end of the long prominent muscle 12 and positioning column
10 are connected, and prominent muscle can prevent the ontology of vacuum bag from touching gas vent 14, influence to vacuumize, and the connection type of positioning column 10 can
So that positioning column 10 is in vacant state, do not influence to vacuumize.
The upper edge of the gas vent 14 is provided with a circle seal convexity 9, and seal convexity 9 is in contact with valve block 3, prevents out
The case where existing gas leakage, improve the effect of sealing.
The thickness of the marginal portion of the gasket body 33 is less than the thickness at middle part, the upper table of the gasket body 33
Face is rough surface, and lower surface is shiny surface, in order to which vacuum bag is more prone to produce deformation by compression back edge.
As a kind of embodiment of the invention, when in use, upper cover 2 is up mentioned, support column 7 does not push down valve block
3, the flooded suction of vacuum pump entangles upper cover 2, is vacuumized, and valve block 3 can be moved down gradually when vacuumizing, and inserting column 31 is inserted
Enter into positioning column 10, gasket body 33 can be deformed gradually, toward contract, firmly sealed gas vent 14, then pressed upper cover 2
Under.
If the gas of extraction is less, in the insufficient situation of external and internal pressure, contact area may between bottom valve 1 and valve block 3
Will not be complete, it is easy for generating gas leakage.The effect of upper cover 2 is that in position, support column 7 gives valve block 3 one supports, is allowed
It cannot rebound up completely, and auxiliary guarantees that air valve should not gas leakage.
The configuration of the present invention is simple, components are few, using completely new valve block and upper cover, have good sealing effect.
