Abstract
The open a kind of two bag combination Non-return air valves of the present invention and ventilated footwear thereof, comprise as the pouch of iris action with as the sack of valve body, pouch is sleeved in sack, and air inlet pipe one end is connected center with sack and pouch respectively and communicates, and escape pipe one end is connected center with sack and communicates, the other end of pouch is two film adhered inlet channels, in the time that the pressure in air inlet pipe is greater than the pressure of outer bag, two film adhered inlet channel conductings, otherwise, two is together film adhered, inlet channel closure. A kind of ventilated footwear, the ventilated footwear that two bag combination Non-return air valves are installed, the middle end of ventilated footwear, is provided with the large end groove matching with two bags of combination Non-return air valves. Beneficial effect of the present invention: highly sensitive, narrow-minded, between zero to negative pressure MPa0.01, just can start.
Description
Technical field
The Non-return air valve that the present invention relates to be used in conjunction with in ventilated footwear and ventilated footwear thereof, particularlyMake air in air valve, do one-way flow, can not allow air flow backwards device and the ventilation of applicationFootwear.
Background technology
At present, footwear are divided into two kinds with Non-return air valve both at home and abroad, and one is two hemispheric softwaresGoods are docking together, and as flap, when air valve body is subject to negative pressure, hemisphere is by malleation direction gasStream is washed open, and air flows through; While being subject to malleation, hemisphere sealing, air-flow blocking-up, this air valveShortcoming be, while having impurity in air, air valve blocking-up air-flow function reduces, meanwhile, this gasValve is large-minded.
Another is spring plug-back type, good sealing effect when this spring for valve pressure is large, butAir valve sensitivity is not high; Spring pressure hour, highly sensitive, but sealing effectiveness is bad, causesConflicting.
Summary of the invention
For the deficiency of above-mentioned technology, the invention provides a kind of two bag combination Non-return air valves of havingVentilated footwear, this air valve is highly sensitive, narrow-minded, between zero to negative pressure MPa0.01 justCan start.
To achieve these goals, the technical solution used in the present invention is:
The ventilated footwear with two bag combination Non-return air valves, is characterized in that, comprises the middle end and the large end,On the middle end and the large end, be provided with two bag combination Non-return air valves, the described middle end and the large end be provided withThe two bags of grooves that combination Non-return air valve matches, the two bag combination Non-return air valves that enter comprise conductThe pouch of iris action and as the sack of valve body, pouch is sleeved in sack, air inlet pipe one endBe connected center with sack and pouch respectively and communicate, escape pipe one end is connected center with sack and communicates,The other end of pouch is two film adhered inlet channels, when the pressure in air inlet pipe is greater than sackPressure time, two film adhered inlet channel conductings, on the contrary two is together film adhered,Inlet channel closure; The length that air inlet pipe is stretched out in pouch be little bag length 1/5 within;Described pouch is to hotly join to form the bag-shaped of path.
Beneficial effect of the present invention: highly sensitive, narrow-minded, zero to negative pressure MPa0.01Between just can start.
Brief description of the drawings

The longitudinal sectional view of Fig. 2, Fig. 1;
The transverse sectional view of Fig. 3, Fig. 1.
Detailed description of the invention
As shown in the figure, two bags of combination Non-return air valves, comprise pouch 2 and work as iris actionFor the sack 1 of valve body, pouch 2 is sleeved in sack 1, air inlet pipe 3 one end respectively with sackCommunicate with pouch 2 connection centers, escape pipe 4 one end are connected center with sack 1 and communicate, pouch2 the other end is two film adhered inlet channels, when the pressure in air inlet pipe 3 is greater than sackWhen the pressure of 1 (valve pocket), two film adhered inlet channel conductings, on the contrary two films pasteBe combined inlet channel closure. Step on the air chamber of ventilated footwear when pin, produce after certain air pressure,In air inlet pipe 3, have air-flow to come in, wash the film of two laminatings open, air-flow enters greatly from pouch 2After bag 1, then discharge by escape pipe 4. After pine pin, in air chamber, present negative pressure, air inlet pipe 3While being less than the air pressure of outer bag 1 with the air pressure of pouch 2, the inlet channel closure of pouch 2, pouchFilm tightly fit together, ventilating air passage is closed. Pouch 2 be two films hotly join form logicalRoad bag-shaped is only that film just can be fitted. Sack wall is thicker, for swelling shape cavity. EnterTracheae 3 one end hotly join and are connected center and communicate with sack 1 and pouch 2 respectively; Escape pipe 4 outer withSack 1 hotly joins connection center and communicates, and so just can not leak gas, and is fixed together. Air inlet pipe 3The length of stretching out in pouch 2 is 1/5 of pouch 2 length, is difficult for longly, and air-flow is easierBlocking-up.
