Abstract
The utility model discloses an anti-fall air valve nozzle, which comprises a rubber pad of the air valve nozzle, a rod of the air valve nozzle and a base of the air valve nozzle with a root part positioned in the rubber pad of the air valve nozzle. The surface of the rubber pad of the air valve nozzle is attached with a skeleton frame layer. By using the technical scheme of the utility model, fiber fabrics, such as two layers of nylon tire fabrics or 1400 tax/2 builder fabrics, are stuck on the rubber pad of the air valve nozzle in a crossing form of 90 DEG (or certain angles) and cover the whole rubber pad before the inner tire is vulcanized. The rubber pad is additionally provided with one layer of nylon skeleton material, and the rubber pad of the whole air valve nozzle and air valve nozzle are tightly held to ensure that the air valve nozzle of the inner tire can not fall during work. Leftover materials of the tire of the wheel tire can be utilized to reduce waste.
Description
Technical field
The utility model relates to a kind of inner tube of a tyre anticreep tire tube valve.
Background technology
Inner tube of a tyre finished product all the other materials except that tire tube valve is metal are pure glue goods at present, supporting 23.1-26 plum blossom decorative pattern (G-23) tyre roller that is used for of my company's 23.1-26 inner tube of a tyre, the tire that this tire is used for multiple model drives roller, the part type requires to fill salt solution in the tire, and (ratio of salt and water is 1: 3, reach 3/4 of tyre cavity volume, generally reach about 400kg), purpose is promptly to increase machinery weight to the roller counterweight, reduce mechanical center of gravity, reduce the roller stability of skidding raising machinery in the course of the work, improve the tractive property of tire, through performance is to improve the capacity rating of machinery.The mouthpiece phenomenon of (tire valve and inner tube body are thrown off) had in use appearred taking off in this tire in 2002, further investigation reveals that, this phenomenon occurs in need fill in the inner tube of a tyre in the vehicle that salt solution is liquid ballast, thinks that through serious analysis the major cause that causes mainly contains following 2 points:
(1), salt solution is to the corrosion attack of tire tube valve.
Tire tube valve is the brass metal material, salt solution is owing to there is certain potential of hydrogen, can complicated electrochemistry reflection take place with tire tube valve, thereby the tire tube valve place that uses metal and rubber interface produces corrosion and peels off, according to test, with the tire tube valve of belt glue pad be placed on soak 7 days in the salt solution that proportioning is 1: 3 (1 part in sodium chloride, 3 parts in a water) after, tire tube valve mouth body will produce with rubber cushion and peel off.According to the test of tire tube valve manufacturer, the tire tube valve of belt glue pad was placed in the salt solution after 14 days, tire tube valve can come unglued fully with rubber cushion.
(2), inner tube valve is subjected to big shearing stress in the work
Add the about 400kg of salt solution in the inner tube of a tyre, account for 70% of tyre cavity volume, and tire uses air pressure lower, machinery is in operation process during the forward-reverse crank motion, the cover tire and the inner tube of a tyre can produce relative displacement, and tire tube valve is owing to can not be moved with the inner tube of a tyre by the constraint of wheel rim valve slot, and tire tube valve is subjected to the shearing of wheel rim and the inner tube of a tyre and quilt is turned round bad.
Summary of the invention
The utility model is in order to solve the technical matters that inner tube of a tyre finished product tire tube valve comes off easily, a kind of anticreep tire tube valve to be provided.
For achieving the above object, the utility model adopts following technical scheme: a kind of anticreep tire tube valve, comprise that tire tube valve rubber cushion, tire tube valve bar and root thereof are positioned at the valve base of tire tube valve rubber cushion, and described tire tube valve rubber cushion surface is pasted with casing play.
Described casing play is two-layer nylon layer nylon cloth, and the woven design of two layers of cloth intersects at an angle and is attached on the tire tube valve rubber cushion and covers whole rubber cushion surface.
Described casing play is two-layer 1400dtex/2 cord fabric, and the woven design of two layers of cloth intersects at an angle and is attached on the tire tube valve rubber cushion and covers whole rubber cushion surface.
The woven design of described casing play two layers of cloth is 90 degree and intersects and to be attached on the tire tube valve rubber cushion and to cover whole rubber cushion surface.
Adopt technical scheme described in the utility model, before tyre tube vulcanizer, being 90 degree (or certain angle) intersections with fabrics such as two-layer nylon layer nylon cloth or 1400dtex/2 cord fabric is attached on the tire tube valve rubber cushion, and cover whole rubber cushion, this equals to have added one deck polyamide skeleton material on rubber cushion, hold onto whole tire tube valve rubber cushion and valve base tightly, guarantee that inner tube valve can not come off in the work.Can utilize the leftover pieces of diagonal construction tire framework material, cut the waste.
Description of drawings
Figure 1 shows that the utility model structural representation;
Figure 2 shows that the birds-eye view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the outside face of the inner tube of a tyre 5 has a conical tire tube valve rubber cushion 4, the valve base 6 of tire tube valve bar 1 root is positioned at tire tube valve rubber cushion 4, tire tube valve rubber cushion 4 surfaces attach two-layer framework material, casing play is two-layer nylon layer nylon cloth or 1400dtex/2 cord fabric, and ground floor framework material 2 and second layer framework material 3 are 90 degree and intersect and to be attached on the tire tube valve rubber cushion 4 and to cover whole rubber cushion surface.
This technical operation is simple and convenient, casing play also can adopt the fabric web material of other kind, as nylon, rayon, polyester etc., can utilize the leftover pieces of tyre framework material, cuts the waste.
Claims (4)
