Description

Valve for tyre

The present invention's design relates to a kind of transportation class Tire Inflation System, particularly valve for tyre, can reduce inflation times with using tire guarantor's gas time of the gentle goal post of valve inside greatly to prolong.

Existing bicycle, light cavalry, arrange the gas filled device of the general valve insides of small tyre such as car, three-wheel vehicle, the gas filled device of the general valve stake of giant tires such as motor bike, automobile.It protects gas principle all is " air pressure guarantor gas ", promptly utilizes the outside pressure of gas that fills in the tire into to push down valve inside skin or valve stake and reaches the purpose of protecting gas, and only utilized this a kind of guarantor's gas means.Except that car was set off firecrackers, leaks greatly, leaked slowly, mostly general little tire was to fill up and down in ten days return-air, and a hundred or so sky of giant tyre fills return-air.The time of new tyre support will be grown, but it is more less than number; And have quite a few tire often to inflate, and make the people vexatious, usually cause delay.

Why can not most tire be protected gas for a long time? mainly be that people's subtle " permeation " is silently caused.Active because of the solid molecule of gas molecular proportion metal, rubber and plastic, can in the microgap of dirt, spot rust, overflow; Especially road conditions bad, when the capacity of carriage is big, pressure rises and falls in jolting, gas takes advantage of the occasion to escape, and then obviously shortens this gas filed time.But majority are accustomed to this, and to the dust cap on the tire valve, also having on new car, majority is all lost and do not mended, and this more makes guarantor's gas time of tire shorten.Also have, the valve inside skin easily squeezes broken, and the valve pipe collar effect on the rim of being attached to is little etc., also should consider to improve.

The design's purpose is exactly at the deficiencies in the prior art, and a kind of guarantor's device of air of inflation of tire valve is provided, and to prolong the gas time of protecting, to protect tire, is beneficial to production, work and life.

Design mainly is to protect gas to strengthen air pressure, adds that the integrated approach of " pressure-leakage and keeping air " and " the stifled guarantor of glue gas " finishes the work again.The outline of its technical scheme is: change dust cap into the guarantor gas cap; Add guarantor's air-casing at charging valve; Hold concurrently for the valve pipe collar with hexagonal nut; Valve inside is done the change of length; Blended rubber pad, collodion silk are protected gas.

Dust cap (being the outer cap of valve port of valve inside cap and giant tyre) with existing inflation of tire mouth, used instead metal materials such as low carbon stainless steel or copper by common plastics, the cap inner top is stained with firm rubber pad money, and changes filament into, reaching guarantor's gas purpose with mechanical pressure, promptly is to protect gas cap or protect the gas dust cap.

Newly establishing one in the outside of small tyre charging valve and protect air-casing, be made up of base and outer cap, will protect all covers such as gas cap, valve inside hoop, vent pipe, also is pressure-leakage and keeping air, prevents inside and outside the valve inside and the loosening gas leakage of guarantor's gas cap, plays the effect of three guarantor's gas.

Valve pore on the small tyre rim is made big slightly hexagon ring, the hexagonal nut on the inner tube of a tyre is raised to outside the circle, hold concurrently, and accept and protect the air-casing base for the effect of valve pipe collar.

The bar head of valve core bar extended to mouth at the bottom of the valve base flush, to increase the sticker face; The valve inside mouth of pipe is proper extension also, and changes filament into; Valve inside middle part Tuo Luojie descending prolongs, and the gradient reduces, and reduces the compressive load per unit area to rubber, and its air gate is corresponding to move down.

About hexagonal nut and on guarantor's air-casing base attic base, all use rubber cradle, so that tool is pressed back driving fit guarantor gas between parts; At all mouths, comprise that the outer silk of the gentle goal post mouth of valve inside all wants appropriateness to be wrapped with collodion silk, can gas shutoff, prevent that again silk from mouthful becoming flexible, a parts slippage.

The design compared with the prior art, change simple dependence air pressure and protect the prejudice of gas, development and be air pressure, tool are pressed, glue is stifled multilayer, comprehensively protect gas, improved guarantor's gas coefficient widely, its useful effect is obvious: the one, and, dust cap changes guarantor's gas cap into, holds concurrently and can prevent dust, overcome the ignorance of people to original dust cap, list itself can make guarantor's gas time obviously prolong from dustproof; And can overcome people to tire guarantor long point of gas time, short so muddled idea of putting originally.The 2nd,, protect gas cap and set up guarantor's air-casing, and the hexagonal nut rising etc., can play the effect that reduces the folding band, macerates band, reduced inflation times, all can bring convenience work, production and people's life, reduce the loss and cause delay.The 3rd, the design has alerting ability very much, both has been suitable for the complete transformation of existing small tyre charging valve, but the dustproof valve cap of Dan Yibao gas is used for the inflation inlet of large and small tire again, and can make with regard to supporting when making tire and rim.
