Abstract
The utility model relates to motor tire, particularly relates to the valve inside of motor tire, is specially anti-explosion air valve.Anti-explosion air valve, comprise valve inside body, the valve inside valve body that is provided with in valve inside body closes valve port, valve inside body afterbody is provided with bolt hole and negative thread, in bolt hole, coil spring is installed, coil spring is fixedly connected with valve inside body by the spring perch of its end, and helical spring front end holds out against valve inside valve body.The valve port of valve inside body communicates with bolt hole.Spring perch is fixed in the socket bolt hole of valve inside body by screw thread.Can prevent external temperature from changing and the blowing out of causing because tire internal gas pressure increases in running car by actv., provide the safety of tire, the safety of actv. protection driver and crew.
Description
Technical field
The utility model relates to motor tire, particularly relates to the valve inside of motor tire, is specially anti-explosion air valve.
Background technology
Valve inside is airtight core again.The main body of valve inside is a bit of upper end hollow, the cylinder that lower end is solid, and the side opening aperture in lower end and hollow space are connected, and overlaps the resilient thin edge sebific duct of the preceding paragraph below and just forms the overall of special core.It is exactly an one-way cock in fact, and when you inflate a tire, the pressurized air in inflator enters valve inside by hollow space, and resilient India rubber tube " top " is risen, and air enters tire; When not inflating, elastic rubber pipe tightens up, and covers the aperture of side, and air can not be refluxed from tire.Existing valve inside cannot open pressure release automatically, and in time being cold with thermal conversion, the gas of inside tires there will be expansion pressure rising and causes blowing out.
Summary of the invention
Cannot releasing pressure automatically for existing tyre valve, tire pressure raises and easily generates the problem of blowing out, and the utility model provides a kind of anti-explosion air valve.
Design plan of the present utility model is: anti-explosion air valve, comprises valve inside body, and the valve inside valve body that is provided with in valve inside body closes valve port, and valve inside body afterbody is provided with screw and negative thread.Install coil spring in screw, helical spring front end holds out against valve inside valve body, and helical spring end is connected on spring perch.Spring perch is fixedly connected with by screw thread with valve inside body.Have standard socket bolt hole in spring perch, facilitate mounting spring seat.
The valve port of valve inside body communicates with the standard socket bolt hole of spring perch, outwards exits during for opening valve inside valve body.
Described spring perch is fixed in the screw of valve inside body by screw thread.
Anti-explosion air valve is arranged on tire inner tube or on tubeless wheel rim.Time force value before tire internal gas pressure reaches the limit of blowing out (fixed according to design value), gaseous tension can overcome helical spring power to be pushed open the valve inside valve body of anti-explosion air valve, gas will be gone to air by socket bolt hole in tire, carry out pressure release.When tyre inner pressure reduces, valve inside valve body upwards pushes up by helical spring elastic force, returns to home position, closes valve, makes gas confinement in tire.
The utility model is not when changing original valve inside unitized construction; only increase a kind of explosion-proof check valve of tyre core apparatus; cost increase is very little; but can actv. prevent external temperature from changing and in running car because the increase of tire internal gas pressure blowing out of causing; there is provided the safety of tire, the safety of actv. protection driver and crew.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1---tire, 2---anti-explosion air valve body, 3---valve inside valve body, 4---coil spring, 5---helical spring seat, 6---screw thread, 7-standard socket bolt hole, 8---screw.
Detailed description of the invention
Below in conjunction with specific embodiment and Figure of description, the utility model is described in further detail.Specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
Embodiment: as shown in Figure 1, explosion-proof check valve of tyre core, anti-explosion air valve body 2 is arranged on tire 1, and anti-explosion air valve body 2 opens screw 8, arranges negative thread 6 in hole, installs valve inside valve body 3 in anti-explosion air valve body 2, closes valve port.Valve inside valve body 3 afterbody arranges coil spring 4, holds out against valve inside valve body 3, push down valve port by coil spring 4.Helical spring seat 5 is connected with bottom coil spring 4.Helical spring seat 5 and anti-explosion air valve body 2 are connected and fixed by screw thread 6, are fastened in screw 8.Standard socket bolt hole 7 is opened in helical spring seat 5.Valve port, the screw of anti-explosion air valve body 2 communicate with standard socket bolt hole 7 three, and valve port is closed by valve inside valve body 3 in centre.
Wherein helical spring seat 5 and anti-explosion air valve body are connected and fixed by screw thread 6, and coil spring 4 holds out against valve inside valve body 3, compress valve port.The pressure size of coil spring 4 pairs of valve inside valve bodies 3, i.e. pressure of tire limit, by the determining positions of adjustment helical spring seat 5 in screw.Inner-hexagon spanner is put in the standard socket bolt hole 7 of helical spring seat 5 force value of carrying out install and adjust and blowing out before the limit.Anti-explosion air valve body 2 is connected by techniques such as sulfurations with tire inner tube.Tubeless tire is connected can be undertaken connecting or being threaded by welding with wheel rim.
Explosion-proof check valve of tyre core, achieves the releasing pressure automatically function of pressure of tire, prevents the generation of blowing out.Improve the quality of tire, guarantee driving safety.
Be the utility model preferred embodiment in sum, all changes made according to technical solutions of the utility model, all belong to protection domain of the present utility model when the function of producing does not exceed the scope of technical solutions of the utility model.
