Abstract
The utility model relates to a leak-proof tyre with a high-efficient valve, which is suitable for bicycles and other vehicles. The valve has two-stage leak-proof measures, the existing leak-proof measure of the valve is not changed, a spring leak-proof sheet which can seal a center air vent of the valve is additionally arranged, and the leak-proof effect of the valve is further improved. The spring leak-proof sheet is composed of a spring ring and an elastic gluey leak-proof sheet and is fixed below the end surface of a base of a stud of the valve. The theory of a spring and the difference of air pressure is used for sealing the center air vent of the valve to perform the second-stage leak-proof function. The leak-proof tyre is not easy to pollute and damage, and the leak-proof tyre can not add difficulties for inflating the tyre. Bicycles experiments indicate that the leak-proof effect of the valve of the leak-proof tyre is obviously superior to that a common bicycle tyre.
Description
The present invention is a kind of high-effect valve puncture-proof tire, and it is adapted to bicycle and other vehicle.
At present, the inner tube valve generally adopts the valve inside leakproof of overcoat elastic rubber tube, or adopts a spring piston to form sealing.They all have certain leak preventing effect.But elastic rubber tube is damaged easily; When the wheel load increased the weight of to make the tire internal gas pressure to increase, the leak tightness of valve inside was relatively poor in addition.Spring piston is then easily stained by the dust grains of sand, influences sealing effect.
Task of the present invention is for tire provides a kind of valve with two-stage leak-proof measure, is not promptly changing under the existing leak-proof manner of valve, has increased the spring leakage prevention sheet that can seal valve center gas port, has further improved the leakproof usefulness of tire valve.
The present invention illustrates with a kind of preferential embodiment, and accompanying drawing is made explanations.
Fig. 1, high-effect bicycle valve puncture-proof tire constructional drawing
Fig. 2, have the inner tube air valve structure positive view of spring leakage prevention sheet
Fig. 3, leakage prevention sheet constructional drawing
Fig. 4, spring coil constructional drawing
Leakage prevention sheet shown in Figure 3 is to adopt the elastic gum material to make.Leakage prevention sheet is cut half of by the middle part, edge, form contact smooth upper surface 1 and lower surface 2.But upper surface 1 perforate air guide, lower surface 2 can the confined bed pore.
Spring coil shown in Figure 4 is used to strengthen the sealing effect of leakage prevention sheet, and the both ends of the surface up and down that make leakage prevention sheet are Elastic Contact.
Fig. 2 represents that spring coil 1 and leakage prevention sheet 2 should be fixed in valve double-screw bolt base end face, and the three is connected as a single entity, and as a kind of preferential fixed form embodiment, can adopt powerful viscous adhesive to be adhesively fixed on valve double-screw bolt base end plane.
Fig. 1 is along the local longitudinally sectional drawing of inner tube.During to Tyre inflating, because the tire internal gas pressure is low, the lower surface that air-flow can be pushed spring leakage prevention sheet 2 open enters in the tire.After being full of gas, the spring leakage prevention sheet can make that gas is isolated from the outside in the tire, plays sealing process.In case valve inside 3 gas leakage, under the double action of spring and tire inner and outer air pressure difference, the upper and lower end face of spring leakage prevention sheet 2 is adjacent to more, confined bed pore 4, performance second stage leakproof usefulness.Particularly when the wheel load increased the weight of to make the tire internal gas pressure to raise, spring leakage prevention sheet not only sealing effect was good especially, can also slow down the impact of the interior gas of tire to first order leakproof valve inside.Because the spring leakage prevention sheet is installed on the tire the inside, so it is difficult for stained.
Show through cycle test: the valve inside of tire of the present invention is extracted, and the spring leakage prevention sheet can seal gas in the tire and leakproof.Bicycle jolts when travelling at potted road surface, and the valve leakproof usefulness of tire of the present invention obviously is better than common tire; The present invention can not add to the difficulties to Tyre inflating in addition.
Claims (3)
1, the high-effect valve puncture-proof tire that has the two-stage leak-proof measure, it is characterized in that: on the valve leakage-proof structure of conventional tyre, increase a spring leakage prevention sheet 2 that utilizes draught head principle sealing valve center gas port, it is fixed in the plane, bottom of inner tube valve stud head 1, plays second stage leakproof effect.
2, according to the described high-effect valve puncture-proof tire of claim 1, it is characterized in that: spring leakage prevention sheet 2 is made of jointly spring and leakage prevention sheet, spring is to make with steel material, can strengthen the sealing usefulness of leakage prevention sheet, leakage prevention sheet is made with elastic colloidal material, and a smooth contact surface that plays the confined bed stomatal action is arranged.
3, according to claim 1,2 described high-effect valve puncture-proofs tire, it is characterized in that: the two-stage leak-proof measure can be distinguished single-stage and independently seal gas in the tire, all has leakproof usefulness.
