Description
Technical Field
The utility model relates to a valve, specifically say that an use one-way valve of holding of gas on vacuum compression bag.
Background
Need use the valve on the vacuum compression bag, the valve plays the effect of connecting the pump bowl and preventing vacuum compression bag gas leakage, and prior art's vacuum compression bag valve generally includes valve body, valve gap and sets up the sealing washer between valve body and valve gap, and the valve gap passes through threaded connection's mode and is fixed with the valve body, and not only the structure is complicated, and sealed effect is not very ideal yet.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned drawbacks of the prior art, the present invention is directed to: the one-way air-tight valve is simple in structure and good in sealing effect.
The technical solution of the utility model is that: one-way airtight valve, including valve body and valve gap, the valve gap lower extreme has from interior to the joint post that distributes in proper order outward, first bulge loop and second bulge loop, the center of valve body has the jack that link up from top to bottom, and the valve body upper end has and is annular first draw-in groove and second draw-in groove, a plurality of gas pockets have on the inner wall of first draw-in groove, the joint post, first bulge loop and second bulge loop block respectively into the jack, in first draw-in groove and the second draw-in groove, and first bulge loop, the second bulge loop closely laminates with the inner wall of first draw-in groove, second draw-in groove respectively.
Furthermore, the lower extreme of joint post has the plush copper, and the lower extreme of jack has the joint platform, and the plush copper card is in joint platform surface.
Further, the first bulge loop and the second bulge loop are respectively tightly attached to the inner walls of the first clamping groove and the second clamping groove, which means that: the first convex ring and the second convex ring are in interference fit with the first clamping groove and the second clamping groove respectively.
Further, the top of the valve cover is provided with a convex handle.
Further, the valve gap is the silica gel material.
Use the utility model provides an one-way air-lock valve, its beneficial effect is: the valve consists of a valve body and a valve cover, and has a simple structure; the clamping column, the first convex ring and the second convex ring are clamped into the jack, the first clamping groove and the second clamping groove respectively, and the first convex ring and the second convex ring are tightly attached to the inner walls of the first clamping groove and the second clamping groove respectively, so that the one-way air-tight valve has a multiple sealing effect and is good in sealing performance.

fig. 2 is another overall structure diagram of the present invention;
FIG. 3 is an exploded view of the present invention;
fig. 4 is another exploded view of the present invention;
fig. 5 is a schematic cross-sectional view of the present invention.
Shown in the figure: the valve comprises a valve body 1, a valve body 11, a jack 111, a clamping platform 12, a first clamping groove, a 121 air hole, a 13 second clamping groove, a valve cover 2, a 21 clamping column, a 211 raised head 22, a first convex ring, a 23 second convex ring and a 24 handle.
Detailed Description
For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:
as shown in fig. 1 to 5, the one-way air-tight valve includes a valve body 1 and a valve cover 2, the lower end of the valve cover 2 has a clamping column 21, a first protruding ring 22 and a second protruding ring 23 which are sequentially distributed from inside to outside, the center of the valve body 1 has a through hole 11, the upper end of the valve body 1 has a first clamping groove 12 and a second clamping groove 13 which are annular, the inner wall of the first clamping groove 12 has a plurality of air holes 121, the clamping column 21, the first protruding ring 22 and the second protruding ring 23 are respectively clamped into the through hole 11, the first clamping groove 12 and the second clamping groove 13, and the first protruding ring 22 and the second protruding ring 23 are respectively tightly attached to the inner walls of the first clamping groove 12 and the second clamping groove 13.
As shown in fig. 2, 4 and 5, the lower end of the snap-in post 21 has a boss 211, the lower end of the insertion hole 11 has a snap-in table 111, and the boss 211 is snapped on the surface of the snap-in table 111, so that the valve cover 2 can be firmly fixed on the valve body 1.
As shown in fig. 5, the tight fitting of the first protruding ring 22 and the second protruding ring 23 with the inner walls of the first slot 12 and the second slot 13 means that: the first convex ring 22 and the second convex ring 23 are in interference fit with the first clamping groove 12 and the second clamping groove 13 respectively, so that the one-way air-tight valve has multiple sealing effects and good sealing performance.
As shown in fig. 1, 3 and 5, the top of the valve cover 2 has a protruding handle 24 to facilitate the removal of the valve cover 2.
The valve cover 2 is made of silica gel, has good elasticity, is convenient to be disassembled and assembled with the valve cover 2, and also improves the sealing effect of the one-way air-tight valve.
It is to be understood that the foregoing is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, which is defined by the following claims and drawings.
