Description

Vacuum bag air valve

Technical field

The utility model is related to check valve technical field, more particularly to a kind of vacuum bag air valve.

Background technology

Vacuum bag can be used to store various clothes and household articles, such as clothing, quilt cover etc., it by detaching air, So that the article stored is isolated from the outside, can not only prevent mouldy, and can also be by the clothing stored, quilt cover with air Detach reduction volume, final compression is got up, and is convenient to people and carries and preservation.The vacuum bag is provided with a pumping, deflates Air valve, by air valve connect aspiration pump, so as to by vacuum bag air extract out, extract out air after, air valve sealing pass Close, just can prevent air from entering, if necessary to deflate, then need to only open air valve and just may be used；The air valve of vacuum bag will on the market at present Complex structure, high cost, or simple structure, sealing effectiveness is bad.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of vacuum bag air valve, and the structure of the air valve is relatively simple It is single, low cost of manufacture, and good sealing effect.

For solving above-mentioned technical problem, technical solution adopted in the utility model is：A kind of vacuum bag air valve, its feature It is：Add circle and valve gap including valve seat, silica gel valve element, rubber, the valve seat includes riffled tube and is fixed on internal thread Base on pipe, the base are fixedly connected with vacuum bag, and the vacuum bag in riffled tube is provided with pore, the rubber Glue adds upper side end of the snare located at the riffled tube, and the silica gel valve element includes cartridge cover and is fixed on the downside of cartridge cover Valve rod, the valve rod are inserted in the pore, and the pore is blocked, and the valve gap includes valve cover and is fixed on the valve The valve gap post of cover plate lower end, the valve gap post are provided with external screw thread, and the valve gap post is adapted with the riffled tube, when described When valve gap is screwed, the lower end of valve gap post is contacted with the cartridge cover, and institute's cartridge cover is pressed onto on the vacuum bag, and valve cover with The rubber adds circle directly contact, makes rubber add circle and certain deformation occurs.

Further technical scheme is：Rubber blanket is fixed in the lower end of the valve gap post, and the diameter of the rubber blanket is less than The diameter of valve gap post.

Further technical scheme is：The valve rod includes the first valve rod and the second valve rod, and second valve rod is fixed In the lower end of first valve rod, and the diameter of first valve rod is less than the diameter of the second valve rod, first valve rod it is straight Footpath is adapted with the pore.

Using the beneficial effect produced by above-mentioned technical proposal it is：The air valve only includes several devices, manufacture craft Simply, low cost of manufacture；The air valve uses dual-seal, cooperation of first resealing for valve gap post and cartridge cover, the second weight Add the cooperation between circle for valve cover and rubber, by using dual-seal, improve sealing effectiveness.

Additionally, rubber blanket, the rubber blanket and institute during the valve gap is screwed are fixed in the lower end of the valve gap post State cartridge cover to contact, can make the rubber blanket that certain deformation occurs, make sealing effectiveness more preferable.The diameter of first valve rod Less than the diameter of the second valve rod, the diameter of first valve rod is adapted with the pore, is deflated when the valve gap is opened During, can prevent the valve element from skidding off from pore, card effectively prevents which from losing.
