Abstract
A tire inflation valve comprises a valve with air inlet, a valve cover with air outlet and a movable spool arranged in the valve with the front part in the air outlet of the valve cover. The center of the movable spool is provided with an arbor collar, the front shaft shoulder of the collar is agglutinated with a seal cushion and the cushion is facing the internal end of the valve cover in the air outlet. The air outlet of the valve cover has two cylindrical holes of same axle but different internal diameter and the external section of larger internal diameter is matched with the external diameter of a tier inflation nozzle. The front part of the movable spool has two sections; the external section is cylindrical and the external diameter of the section is corresponding to the external diameter of a valve core in the tire inflation nozzle; the internal section and the external cylinder of same axle are oblate by symmetrically clipping two lateral surfaces; and two remaining arcs of the oblate shape are matched with the internal cylindrical hole close to the air outlet of the valve cover.
Description
Affiliated technical field
The utility model relates in the tire composing room in motorcycle assembly plant, concentrates the gas charging valve that tire is inflated.
Background technique
In the tire composing room in motorcycle assembly plant, be to concentrate the tire that has assembled is inflated.For this reason, people's design is specifically designed to the concentrated inflator of this occasion, for example: " the rotation inflator " of " Chongqing Lifan Industry (Group) Co. Ltd. ".Gas charging valve in this device is by the valve body of bringing gas port into, by the valve gap of air outlet be contained in movable spool that its front portion in the valve body is arranged in the valve gap air outlet etc. and form.There is a circle axle collar at movable spool middle part, on the preceding shaft shoulder of this axle collar seal rubber pad is installed, and the another side of sealing rubber cushion is facing to the valve gap interior edge face in the air outlet.There is a circle pressure spring to be enclosed within the rear portion of movable spool and to support on the back shaft shoulder of its axle collar; The other end of this spring is installed and is withstood on the spring seat that is positioned at described valve body afterbody.The air outlet of described valve gap is two sections coaxial and cylindrical holes that internal diameter is different.Its outer sector hole internal diameter is big, be Spielpassung with the external diameter of tyre inflation mouth; Have a seal ring to be installed on the end face of these two sections cylindrical hole connecting places, the endoporus aperture of sealing circle is identical with this inner cylindrical aperture.Deficiency is: the front portion of movable spool (just its top can be withstood by valve inside part) be one section cylindrical.When between the hole than minor diameter bigger gap being arranged when this columniform external diameter and air outlet, tyre inflation is very fast.But after having inflated, during movable spool return, skew can take place usually and make poorly sealed.Like this, not only air leakage is big, causes the waste of the energy; And noise pollution is also serious.When being suitable Spielpassung between the hole than minor diameter when this columniform external diameter and air outlet, the time of tyre inflation is oversize again, has influenced manufacturing efficiency widely.
Summary of the invention
The purpose of this utility model provides a kind of charging efficiency height, and the tyre tube valve of gas leak phenomenon can not take place after stopping to inflate.
Realize a kind of tyre tube valve of described purpose, by by the valve body of bringing gas port into, by the valve gap of air outlet be contained in movable spool that its front portion in the valve body is arranged in the valve gap air outlet etc. and form.There is a circle axle collar at movable spool middle part, on the preceding shaft shoulder of this axle collar seal rubber pad is installed, and the another side of sealing rubber cushion is facing to the interior edge face in the valve gap air outlet.The air outlet of described valve gap is two sections coaxial and cylindrical holes that internal diameter is different, and its outer sector hole internal diameter is big, be Spielpassung with the external diameter of tyre inflation mouth.Improved aspect is: the front portion of described movable spool has two sections, and its outer section is cylindrical, and the valve inside external diameter in external diameter of this section and the tyre inflation mouth is suitable.Its inner section be with outer one section coaxial cylindrically be flat garden shape by the symmetry bi-side of pruning, one section inner cylindrical hole of two sections circular arcs of this flat garden shape and described valve gap air outlet is Spielpassung---the distance between the bi-side of being pruned by symmetry equals its one section outer columniform external diameter.Be installed in that the seal rubber pad on the shaft shoulder is bonded on this preceding shaft shoulder before the axle collar of described movable spool.
Because one section inner cylindrical hole of anterior inner one section remaining two sections circular arc of movable spool and valve gap air outlet is Spielpassung, so with bigger the comparing in the sort of gap in the background technique, the utility model centering is good.So the phenomenon that can not leak gas after stopping to inflate wastes energy and the problem of noise just has been overcome naturally.Wherein, seal rubber pad is bonded on the preceding shaft shoulder, more unobstructed in the time of making inflation; Seal rubber pad can guarantee sealing more reliably.Again because the distance that this part of movable spool has been pruned between bi-side and bi-side symmetrically equals its one section outer columniform external diameter.So with less the comparing in the sort of gap in the background technique, the speed of the utility model inflation is faster, manufacturing efficiency also is improved.

Embodiment
A kind of tyre tube valve, it includes valve body 1, the valve gap 2 that air outlet 21 is arranged of bringing gas port 11 into and is contained in the movable spool 3 etc. that its front portion in the valve body 1 is arranged in valve gap 2 air outlets 21.There is a circle axle collar 31 at movable spool 3 middle parts, are bonded with seal rubber pad 4 on the preceding shaft shoulder of this axle collar 31, and rubber cushion is facing to valve gap 2 interior edge faces in the air outlet 21.There is a circle pressure spring 5 to be enclosed within the rear portion of movable spool 3 and to support on the back shaft shoulder of its axle collar 31; The other end of this spring 5 is installed and is withstood on the spring seat 6 that is positioned at described valve body 1 afterbody.Valve body 1, valve gap 2 and spring seat 6 all have the sealing gasket sealing therebetween respectively by scyewed joint.The air outlet 21 of valve gap 2 is two sections coaxial and cylindrical holes that internal diameter is different, and its outer sector hole internal diameter is big, be Spielpassung with the external diameter of tyre inflation mouth.Have a seal ring 22 to be installed on the end face of these two sections cylindrical hole connecting places, the endoporus aperture of sealing circle 22 is the same with inner cylindrical aperture, can guarantee charging efficiency, also can gas leakage when inflation.The front portion of described movable spool 3 has two sections, and its outer section 32 is cylindrical, and the valve inside external diameter in external diameter of this section 32 and the tyre inflation mouth is suitable.Its inner section 33 be with outer one section 32 coaxial cylindrically be flat garden shape by the symmetry bi-side of pruning, two sections circular arcs of this flat garden shape and described valve gap 2 air outlets, 21 one section inner cylindrical hole are Spielpassung---the distance between the bi-side of being pruned by symmetry equals its one section 32 outer columniform external diameter.
During to tyre inflation, the wheel that installs tire is placed on " rotation inflator ", allow its charging air inlet aim at the preceding air outlet of the utility model valve gap.Under the action of gravity of wheel, the valve inside in the charging air inlet backs down movable spool downwards, begins inflation.After inflation is finished, take off wheel, movable spool is under the effect of spring force, and Jiong closes gas circuit in the position.
