Description

Gas-liquid dual-purpose tire tube valve

Technical field

The utility model is a kind of novel gas-liquid dual-purpose tire tube valve that is used for inflation of tire and perfusion tire patching mixing material.

Background technology

In the mouth body 20 of the tire tube valve of existing structure among wheel rim 10 valve inside 30 is only arranged, see also accompanying drawing 1. Fig. 2 and illustrate the state that tire tube valve is inflated, mark 11 expression gas flow channels, mark 22 is the slit, its principle of work is, the below of wheel rim 10 is inside tires (just valve inside 30 lower parts is in inside tires), when the core bar of depressing valve inside 30 tops (not shown go out), the valve of valve inside 30 is opened, air communication is crossed the inner chamber (also having parts such as spring and core bar in the chamber) of valve inside 30, pass through the slit 22 of 20 of valve inside 30 and mouth bodies again, enter the inside tires inflation.Because gas flow channel 11 is the inner chamber and the slit of valve inside 30, not only the cross section is less, and the cross section has been divided into several difform small bores, resistance is very big when therefore passing through for liquid, if have the particle of some in the liquid, then can be in valve inside inside or the place, slit be stuck and result in blockage, therefore the tire tube valve of this structure is not suitable for by liquid, more impassabitity is mixed with the liquid of particle.

Summary of the invention

In order to address the above problem, the utility model does not adopt traditional valve core structure, but adopts the core bar of a complete round section central aisle, and moving up and down of core bar is the conversion of closing and opening.On the one hand thick liquid by the time resistance very little, on the other hand for being blended in the liquid, also can enter tire by circular channel less than the particle object of channel diameter.

The purpose of this utility model is, a kind of gas-liquid dual-purpose tire tube valve is provided, by improving the structure of tire tube valve, valve inside and two kinds of structures of tire tube valve mouth body are united two into one, and employing central aisle, gas and thick liquid all can be passed through, make tire flat, do not need to dismantle tire tube valve when puncturing or leaking and just can charge tyre repairing fluid.

The technical solution adopted in the utility model is that a kind of gas-liquid dual-purpose tire tube valve comprises rubber layer and mouth body, it is characterized in that, further comprises:

Core bar is arranged on mouth body central authorities, and a hollow mesopore is arranged, and the close end position offers a transverse holes on described core bar, and the mesopore of described core bar communicates with transverse holes, and the outboard beam wall of described core bar and the endoporus of mouth body are free-running fits;

Ringlet is arranged on the nearly upper outside of core bar and moves with described core bar;

Spring is positioned at the core bar outer peripheral face of mouth body, and described Spring Card is located between the step that ringlet and the inboard middle position of mouth body form;

Seal gasket, affixed with the core bar of the lower end of described transverse holes.

Description of drawings

Below, with reference to accompanying drawing, for those skilled in the art that, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.

Fig. 1 is existing tire tube valve closed condition scheme drawing;

Fig. 2 inflates view for existing tire tube valve;

Fig. 3 is the tire tube valve closed condition scheme drawing of the utility model one preferred embodiment;

Fig. 4 is the scheme drawing of tire tube valve inflation (liquid) state among Fig. 3.

The specific embodiment

See also Fig. 3, the utility model comprises rubber layer 5 and the mouth body 4 in traditional tire tube valve equally, the difference part is, the core bar 1 that mesopore 9 is arranged in mouth body 4 central authorities built-in, the close end position offers a transverse holes 8 on core bar 1, the mesopore 9 of core bar 1 communicates with transverse holes 8 thus, and the diameter in this two hole 8,9 can be made into greater than 2.5mm, is convenient to by thick liquid or by the particle of diameter less than 2.5mm.The nearly upper outside of core bar 1 is provided with a ringlet 2, and ringlet 2 is combined as a whole with core bar 1, also can adopt turnup structure on core bar 1 top, restriction ringlet 2 to top offset.

This external core bar 1 outer peripheral face also is provided with a spring 3, and spring 3 is fastened between the step 10 of ringlet 2 and the 4 inboard middle positions formation of mouth body.Core bar 1 position in the lower end of transverse holes 8 connects a seal gasket 7.The outboard beam wall of core bar 1 and the endoporus of mouth body 4 are free-running fits.

Position when Fig. 3 is closed condition relation, this moment is because under the effect of spring 3, ringlet 2 upwards promotes core bar 1, and drives seal gasket 7 and upwards tightly push down the anchor ring of mouth body 4 belows and seal.

Fig. 4 provides an inflation body or a liquid state figure, and the utility model needs to use with the rubber cement irrigator when being used to pour into the tire patching mixed liquor.Identical when being used to inflate with normal inflation method.

Using method: when automobile when tire is punctured gas leakage and need pour into tire patching liquid under steam, the rubber cement irrigator is screwed on the screw thread of mouth body 4 upper ends, core bar 1 pressurized moves down in the process of being screwed into, tire patching liquid is through the straight channel of core bar 1, and communicate gradually with inside tires by two side openings in core bar 1 end, until all entering inside tires, under the effect of rubber cement irrigator pressure, the tire patching mixing material pours into inside tires, under the gas leakage suction, arrive the local mending-leakage that tire is punctured rapidly simultaneously.Topping up is finished when back twisting the rubber cement irrigator, and core bar 1 upward movement under the effect of spring 4 drives seal gasket and upwards resets together, is pressed on mouth bar 4 bottom anchor rings, under spring pressure and inner pressure of tire double action, seals inner pressure of tire, and topping up is finished.After connecting the rubber cement irrigator, core bar 1 moves down drive seal gasket 7 and leaves mouth body 4 below anchor rings, thereby the mesopore 9 and the transverse holes 8 of core bar 1 are opened fully, core bar 1 central aisle communicates with inside tires through the transverse holes 8 of bottom like this, gas (liquid) directly enters inside tires through passage, resistance is very little, and is mixed in that the particle less than access opening can not hindered yet in the tyre repairing fluid.

The utility model adopts central aisle, and channel diameter can be made into greater than 2.5mm, can inflate also and can fill thick liquid, in theory can be by containing the mixing material of diameter less than the 2.5mm particle under pressurized state.The utility model adopts central aisle by valve inside and two kinds of structures of tire tube valve are united two into one, and channel diameter is greater than 2.5mm, and gas and liquid all can pass through.Make this tire tube valve under the situation that guarantees normal aerification function, can charge tyre repairing fluid, do not need to dismantle valve inside and just can finish the tire patching function, and gas leak phenomenon does not take place at the tire tube valve place in the tire patching process; Do not dismantle valve inside, tire keeps certain air pressure, and liquid directly arrives leak under the effect of gas leakage water conservancy diversion, just can finish the tire patching function under the situation of not inflating.The tire patching comfort feature and the efficient of motor tire have been improved.
