Abstract
The utility model relates to an air valve for a tire, which comprises an air valve body and a sealing plug, wherein the upper part of an inner hole at the middle part of the air valve body is small and the lower part of the inner hole at the middle part of the air valve body is big. The sealing plug is provided with a small upper part and a big lower part, and is positioned in the inner hole at the middle part of the air valve body. The upper end and the lower end of the sealing plug are respectively sealed with the inner hole at the middle part of the air valve body. The utility model has the advantages of good sealing performance, convenient operation, long service life, simple and reasonable structure, easy fabrication and low cost; when the utility model is used, a tire does not need to be often inflated. The utility model can be used for tires of bicycles, manual cars, tricycles, motorcycles, etc., and can be also used in pressure vessels.
Description
The utility model relates to a kind of tyre valve core, and it can be used for also can be used in the pressurized container on the tires such as bicycle, hand buggy, tricycle, motorcycle.
Existing tyre valve core, be to adopt the valve inside underpart to put the structure of a little rubber anti-gas-leak, because little rubber easily leaks gas, so need often to give tyre inflation when using, and To Be Protected from Heat for little rubber, and aging easily, oiling need often to change little rubber during use, particularly use in summer and torrid areas, the working life of little rubber is shorter.Therefore, use existing tyre valve core,, need to change many times little rubber, use to the user and brought trouble with broken inner tube of a tyre.
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of leak resistance good, and long service life is made and novel tire valve inside easy to use.
The utility model is realized by following design: it comprises valve inside body and Sealing.The endoporus at valve inside body middle part is up-small and down-big, and Sealing adopts and is shaped as up-small and down-big sealing plug, and sealing plug is arranged in the endoporus at valve inside body middle part, the upper and lower end of sealing plug respectively with the endoporus sealing at valve inside body middle part, be two circles sealings.
The diameter of valve inside body bottom diminishes, and its underpart hole wall vertically has 1-5 bar slotted hole groove.The sealing plug underpart is hollow.
The utility model is two circle sealings owing to be provided with the valve inside sealing plug and the endoporus in the middle part of the valve inside body of uniqueness, and it has improved sealability widely, has avoided frequent trouble to the tire qi of chong channel ascending adversely effectively, has brought very big convenience to use; And long service life, a tyre valve core can still can keep excellent sealing performance when using the inner tube of a tyre of broken several tires; Simple and reasonable, easy to manufacture, cost is low again.
Fig. 1 is the vertical sectional structure schematic representation of the utility model.
Fig. 2 is the vertical sectional structure schematic representation of the utility model user mode.
Below in conjunction with accompanying drawing the utility model structure is further described:
Referring to accompanying drawing 1.The utility model is made of valve inside body 1 that is provided with endoporus 5 and sealing plug 2.Valve inside body 1 is divided into upper, middle and lower three parts, and valve inside body top 6 is provided with screw thread, so that the adapted cap is provided with convex shoulder 3 between valve inside body top 6 and the valve inside body middle part 7, so that adapted nut 10; 7 apertures, valve inside body middle part are up-small and down-big; Valve inside body bottom 8 diameters diminish, and its underpart hole wall vertically has 4 slotted hole grooves 4, and its lower end is provided with non-return step 13, and the endoporus of lower end is diminished, and deviate from valve inside body 1 to stop sealing plug 2.Valve inside body 1 can adopt plastics or engineering plastics, also can adopt material time processing such as copper, zinc alloy or aluminum alloy to be shaped.It is that material is made that sealing plug 2 adopts rubber or nylon, sealing plug 2 underparts are hollow, can increase sealing effect, sealing plug 2 is arranged in the endoporus 5 at valve inside body middle part 8, sealing plug 2 is shaped as up-small and down-big, the endoporus 5 that its upper end heads into valve inside body middle part 8 is and heads into sealing, and its lower end contact with the endoporus 5 at valve inside body middle part 8 and is the expansion sealing, i.e. sealing between 8 endoporus 5 of sealing plug 2 and valve inside body middle part is pair to enclose and seals.
During use, referring to accompanying drawing 2.The utility model is directly placed the endoporus 12 of existing tire valve core print seat 11, with nut 10 that the utility model and tire valve core print seat 11 is fastening, with 9 sealings of a rectangular seal, rectangular seal 9 can be enclosed within the upper end portion of valve inside body bottom 8 between valve inside body 1 of the present utility model and the tire valve core print seat 11.Give tyre inflation then, the mouth of supplying gas of pump is aimed at the inner orifice on valve inside body top, the air that comes out from pump enters into endoporus by the inner orifice on valve inside body top, push away under the sealing plug, the gap just appears between sealing plug and the inner hole wall like this, air just enters into the endoporus of valve core print seat by above-mentioned gap from the slotted hole groove of valve inside body endoporus end opening and valve inside body bottom, enter into the inner tube of a tyre of tire at last by the air outlet slit of valve core print seat endoporus bottom, when the tire sufficient gas stops to inflate, because the effect of valve core print seat endoporus hollow adverse QI rushing upwards, sealing plug is upwards pushed up, sealing plug is resetted, even the upper and lower end of sealing plug is two circle sealings with valve inside body endoporus respectively.
