Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

As shown in fig. 1-7. The utility model discloses embodiment relates to a vacuum bag air suspension valve, including bottom valve 1 and upper cover 4, bottom valve 1 be discoid, its upper end is provided with interior cavity 2 between two parties, 4 embeddings of upper cover arrange including in cavity 2, bottom valve 1's bottom be provided with exhaust hole 7 between two parties, exhaust hole 7 in be provided with valve block 3 that can move about from top to bottom, valve block 3 including being umbrella-shaped valve block main part 33 and valve block main part 33 lower extreme set up between two parties imbed the reference column 31 in the reference column 6 of exhaust hole 7 below, the up end middle part of upper cover 4 open and have aspirating hole 10, the downside top surface of upper cover 4 be provided with a plurality of and prevent stifled protruding 9.

As an embodiment of the utility model, when using, cover upper cover 4 with the pump bowl, bleed, as shown in fig. 2, can up lift valve block 3 when bleeding, owing to prevent stifled protruding 9's existence, can leave the space between the middle part of valve block 3 and upper cover 4, bleeder hole 10 can not be stopped up to valve block 3, and the gas in the vacuum bag is given vent to anger from bleeder hole 10 from the middle part that exhaust hole 7 came out to walk around valve block main part 33 and get back to upper cover 4.

At the moment of air exhaust, pressure difference is generated between the inside of the vacuum bag and the external atmospheric pressure, the valve plate 3 in the middle is pushed down instantly by entering from the air exhaust hole 10 at the first time in the process of air backflow, and the insertion column 31 blocks the position of the air exhaust hole 7, so that the valve plate 3 is perfectly attached to the bottom valve 1. Because the valve block 3 is a soft body, the valve block deforms according to the designed shape under the action of the internal and external pressure difference, and is attached to the plane of the bottom valve 1 of the air valve more perfectly.

The center of the upper end of the valve plate main body 33 of the valve plate 3 is provided with the inner concave hole 32, which is beneficial to the deformation of the valve plate main body 33.

The bottom of the bottom valve 1 is provided with a plurality of protruding ribs 11 radially along the periphery of the exhaust hole 7, and the inner side ends of the protruding ribs 11 are connected with the positioning columns 6, so that the sealing effect is good.

The bottom surface of the inner concave cavity 2 is provided with a circle of sealing bulges 5 at the position contacted with the valve plate main body 33, and the sealing effect is good.

The lateral walls of the two sides of the upper cover 4 are symmetrically provided with exhaust gaps 8, so that the air outlet speed can be increased during air exhaust.

As right technical scheme a supplement, prevent stifled arch 9 have 4 and evenly arrange at the middle part of upper cover 4, can guarantee like this to flow complete clearance, can not plug up aspirating hole 10.

The thickness of valve block main part 33 be less than 1.5mm, thickness ratio is thinner is favorable to valve block 3's quick deformation, blocks up the exhaust hole fast.

The utility model discloses simple structure, the appearance is pleasing to the eye, and the exhaust hole can be plugged up automatically to the valve block after accomplishing bleeding, can realize along with taking out along with putting.
