Abstract
The utility model provides a tire explosion-proof inflating valve, by sealing cap (1), aerify sealed mouth (2), connecting pipe (3), rubber body (4) and superpressure discharge valve (5) and constitute, superpressure discharge valve (5) are automatic to be opened when tire internal gas pressure surpasss superpressure discharge valve (5) set pressure value, can automatic recovery close when tire internal pressure drops to superpressure discharge valve (5) set pressure value, make tire internal gas pressure keep at set pressure value. The tire explosion-proof inflating valve can effectively prevent the occurrence of tire burst caused by various factors, particularly prevent the tire burst caused by the fact that the temperature of the tire rises due to heat generated by friction between the tire and a road surface and the pressure of gas in the tire rises synchronously to exceed the compressive strength of the tire under the conditions of high-temperature weather in summer and continuous long-time high-speed driving, and can avoid traffic accidents possibly caused by tire burst.
Description
Technical field
The present invention relates to a kind of explosion-proof air valve of tyre, belong to tire manufacturing technology field, be specially adapted to the explosion-proof of the inner tube of a tyre or inner tube free automobile tyre.
Background technology
Known automobile tyre tire tube valve, have only inflation and sealing function, do not possess the superpressure degassing function, under heavy load, summer high temperature weather and continuous situation of running at high speed for a long time, because the heat that tire and pavement friction produce makes the temperature of tire rise very highly, the pressure of gas also raises synchronously in the tire, the compressive resistance of the tire that rubber is made under hot conditions descends on the contrary simultaneously, when the gaseous tension in the tire surpasses the compressive resistance of rubber tire, will blow out, even may cause traffic accident therefrom.
Summary of the invention
The purpose of this invention is to provide a kind of have superpressure exhaust and auto-reset function, can prevent tire blow-out, prolong the tire explosion-proof air valve of tyre in service life.
Explosion-proof air valve of tyre of the present invention, it comprises sealing cap, gasing sealed mouth, connection pipe and rubber bodies etc., it is characterized in that between connection pipe and the rubber bodies or connection pipe is provided with the superpressure blow off valve.
Described superpressure blow off valve comprises valve body, place the adjusting double-screw bolt in the valve body right hand valve body opening, place the seal ring of regulating between double-screw bolt and the valve body hole, at the spring of regulating between double-screw bolt and the spool, seal ring between valve body and the connection pipe, be positioned at the valve port hole of valve body hole upper end, be positioned at the valve body hole right side, deflation hole between valve port hole and the spool, protecting jacket top is connected with valve body (or rubber bodies), forms annular waste air duct between bottom and the valve body (or rubber bodies), annular waste air duct is connected with deflation hole, the air extractor vent in valve body left side, the air extractor vent upper end communicates with connection pipe, and the lower end communicates with tire.
The spool of described superpressure blow off valve can be non-metallic material or metallic material, if use non-metallic material, be provided with metal gasket or spool is placed in the metallic sheath between spring and spool, the contact surface in the upper end of spool and valve port hole can be plane, sphere or the conical surface.
The upper end, valve port hole of described superpressure blow off valve also can be provided with filtering net and locating bush.
Explosion-proof air valve of tyre outward appearance of the present invention, the same with known automobile tyre tire tube valve except many protecting jackets, installation method also is as good as with known automobile tyre tire tube valve.
Explosion-proof air valve of tyre of the present invention, owing to be provided with the superpressure blow off valve therein, at summer high temperature weather with under the situation of running at high speed for a long time continuously, tire causes in the tire gaseous tension to raise or other unforeseen circumstances causes that gaseous tension raises in the tire because of producing high temperature with pavement friction, all can be by the superpressure blow off valve with the portion gas exhaust to atmosphere, make the interior gaseous tension of tire be controlled at the settling pressure value, prevent the generation of blowing out, simultaneously when inflation of tire, also can easily it be controlled at the settling pressure value, avoid causing tire and pavement friction resistance to increase because of inflation pressure in the tire is not enough, the motor car engine consumption of power increases, or causes blowing out because of inflation pressure of tire is too high.
Description of drawings
Accompanying drawing is the constructional drawing of explosion-proof air valve of tyre embodiment of the present invention.
Shown in the figure:
1-sealing cap, 2-gasing sealed mouth, 3-connection pipe, 4-rubber bodies, 5-superpressure blow off valve, 5-1-valve body, 5-2-regulate double-screw bolt, 5-3-seal ring, 5-4-spring, 5-5-spool, 5-6-seal ring, 5-7-protecting jacket, 5-8-deflation hole, 5-9-annular waste air duct, 5-10-valve port hole, 5-11-valve body hole, 5-12-air extractor vent, 5-13-filtering net, 5-14-locating bush, 5-15-metallic sheath
The specific embodiment
Explosion-proof air valve of tyre of the present invention as shown in drawings, between connection pipe 3 and rubber bodies 4, be provided with superpressure blow off valve 5, it comprises the valve body hole 5-11 that places valve body 5-1 right side, place adjusting double-screw bolt 5-2, seal ring 5-3, spring 5-4, spool 5-5 in the valve body hole 5-11, the valve port hole 5-10 that directly is processed to form by valve body hole 5-11, be positioned at valve body hole 5-11 top, the air extractor vent 5-12 in deflation hole 5-8 between valve port hole 5-10 and the spool 5-5 and valve body 5-1 left side.
The pressure that can bear according to tire is determined the settling pressure value of tire, and the compressive force by regulating double-screw bolt 5-2 regulating spring 5-4 is to setup pressure value.When inflation of tire, sealing cap 1 is pulled down, connecting source of the gas inflates in tire, gas is by gasing sealed mouth 2 and connection pipe 3, the air extractor vent 5-12 in the valve body 5-1 left side of superpressure blow off valve 5 enters tire, the spring force that pressure when gaseous tension in the tire surpasses the settling pressure value in the valve port hole 5-10 overcomes spring 5-4 backs down spool 5-5, gas in the tire is by air extractor vent 5-12, the gap of opening between valve port hole 5-10 and valve port hole 5-10 and the spool 5-5 enters valve body hole 5-11, through deflation hole 5-8 and annular waste air duct 5-9 exhaust to atmosphere, when gaseous tension in the tire is reduced to the settling pressure value, spring force by spring 5-4 automatically resets spool 5-5,5-10 closes with the valve port hole, makes the interior gaseous tension of tire remain on the settling pressure value.
At summer high-temperature weather with under the situation of running at high speed for a long time continuously, because tire and pavement friction produce the temperature build-up that heat makes tire; The pressure of gas also raises synchronously in the tire, when the gaseous tension in the tire surpasses the settling pressure value, as previously mentioned, the spring force that pressure in the 5-10 of valve port hole overcomes spring 5-4 backs down spool 5-5, gas in the tire is by air extractor vent 5-12, the gap of opening between valve port hole 5-10 and valve port hole 5-10 and the spool 5-5 enters valve body hole 5-11, through deflation hole 5-8 and annular waste air duct 5-9 exhaust to atmosphere, when the gaseous tension in the tire is reduced to the settling pressure value, spring force by spring 5-4 automatically resets spool 5-5,5-10 closes with the valve port hole, makes the gaseous tension in the tire remain on the settling pressure value.
The present invention compares with known technology, has following outstanding advantages and effect: had pressure Gas and auto-reset function can prevent effectively that automobile tyre from blowing out, and avoid may causing thus Traffic accident; Permission automobile tyre inner gas pressure is suitable higher and don't meeting is too high, can Reduce tire wear, prolong Using Life of Tyre.
