The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an exhaust valve of vacuum bag, includes valve body and upper cover, the valve body be discoid, its upper end is provided with concave cavity between two parties, the upper cover embedding arrange at the concave cavity, the upside embedding of upper cover arrange and compress tightly the turn button, the bottom of concave cavity install the valve block that covers with exhausting the hole, the both sides lateral wall that compresses tightly the turn button on be provided with the arc spout, be provided with the protruding piece that inlays mutually with the arc spout on the inside wall of corresponding upper cover.

As a supplement to the technical scheme of the utility model, the top that compresses tightly the turn button open and to have the bleeder vent.

As right technical scheme a supplement, the lower extreme of valve block insert the exhaust hole through the back-off spliced pole in.

As right technical scheme a supplement, the outside of upper cover be provided with the spacing retaining ring of round, lean on mutually with the up end of valve body.

As right technical scheme a supplement, the outside of upper cover be located the below of spacing retaining ring and be provided with the round joint arch, this joint arch inlays mutually with the draw-in groove on the interior intracavity lateral wall.

As a supplement to the technical solution of the present invention, the bottom of the valve body has a plurality of protruding ribs along the design of the surrounding radioactivity of the exhaust holes.

Has the advantages that: the invention relates to an exhaust valve of a vacuum bag, which has the advantages of simple structure, few parts, simple and quick compression and locking of a valve plate, no air leakage and good popularization value.

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. 1-3. The utility model discloses embodiment relates to a discharge valve of vacuum bag, including valve body 1 and upper cover 2, valve body 1 be discoid, its upper end is provided with interior concave cavity 6 between two parties, upper cover 2 embedding arrange including in cavity 6, the upside embedding of upper cover 2 arrange and compress tightly turn button 3, the bottom of interior concave cavity 6 install the valve block 5 that covers with exhaust hole 13, the both sides lateral wall that compresses tightly turn button 3 on be provided with arc spout 8, be provided with the protruding piece 4 that inlays mutually with arc spout 8 on the corresponding inside wall of upper cover 2.

The top of the compressing rotary button 3 is provided with an air hole 11, and a vacuum pump sucks air from the compressing rotary button 3.

The lower end of the valve plate 5 is inserted into the exhaust hole 13 through the inverted connecting column 10.

And a circle of limiting retainer ring 7 is arranged on the outer side of the upper cover 2 and is abutted against the upper end surface of the valve body 1.

The outside of upper cover 2 be located the below of spacing retaining ring 7 and be provided with the protruding 9 of round joint, this joint is protruding 9 and is inlayed mutually with the draw-in groove on the inside wall of interior concave cavity 6.

A plurality of protruding ribs 12 are designed radially at the bottom of the valve body 1 along the periphery of the exhaust holes 13, and the problem of blockage caused by the fact that a vacuum bag is tightly attached to the exhaust holes 13 can be prevented by the protruding ribs 12.

Examples

When the vacuum bag is used for air extraction, the valve body 1 is embedded in the vacuum bag and is connected through hot melting, then the upper cover 2 is in butt joint with the air extraction pump, the compression rotary button 3 is in a unscrewed state, under the action of the air extraction pump, an air pressure difference is formed between the interior of the vacuum bag and the air extraction pump, the valve block 5 is pushed upwards by air in the vacuum bag under the action of the air pressure difference, then the inverted connecting column 10 moves upwards, a gap is formed between the valve block 5 and the bottom end of the inner cavity 6, the air in the vacuum bag passes through the exhaust hole 13 at the bottom end of the valve body 1, the air extraction pump is closed after air extraction is completed, the air pressure in the vacuum bag is smaller than the external air pressure, the air holes and the central hole can be blocked by the valve block 5 under the action of the air pressure difference, the air extraction pump is removed.

The utility model discloses simple structure, spare part is few, and to compressing tightly of valve block locking simple swift relatively moreover, the condition of gas leakage can not appear, has fine spreading value.
