Abstract
The invention relates to a tire explosion-proof device which comprises a cylinder body, wherein a valve core is arranged in the cylinder body; a press spring positioned inside the cylinder body is arranged at the upper part of the valve core; a pressure relief opening is formed in the side wall of the cylinder body; a regulating spring is arranged at the upper part of the press spring; an outlet at the lower part of the cylinder body is connected with a cycle valve of a tire through a cycle valve connecting pipe. The tire explosion-proof device has the advantages of simple and compact structure, reliability, small size and light weight. The tire explosion-proof device has the advantages of no delay and rapid response due to the fact that the valve core is driven to move under the action of differential pressure. In addition, the tire explosion-proof device is safe and reliable. Therefore, the application range is wide.
Description
Technical field
The present invention relates to a kind of explosion-protection equipment of tyre.
Background technology
At present, in order to prevent tyre explosion, existing multiple explosion-protection equipment of tyre on the market: such as the tire pressure monitoring explosion protection.Part tire pressure monitoring explosion protection also is equipped with warning device simultaneously, as utilize tire pressure raise to promote to be contained in connecting rod trigger alarm device in the cylinder, but because its unreliability that exists machinery to trigger, in case parts occur aging or loosening, trigger alarm timely just often; And in the situation of high pressure, namely can trigger alarm, even also can't automatically carry out release to tire, there is the potential safety hazard of blowing out, functional reliability is poor, and safety performance is low.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defects that prior art exists, and provides a kind of functional reliability good, the explosion-protection equipment of tyre that safety performance is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of explosion-protection equipment of tyre, comprise cylinder body, be provided with spool in the cylinder body, spool top is provided with the pressure spring that places cylinder interior, have pressure relief opening on the cylinder side wall, pressure spring top is provided with regulating spring, and the inferior part of the cylinder block outlet is connected with tire valve by the tire tube valve connection pipe.
Further, the preferred I shape spool of described spool.
The present invention is by the spool of common check valve in the similar hydraulic efficiency pressure system, in and the situation greater than the preset pressure of pressure spring too high at tyre inner pressure, tire inner high voltage gas backs down spool, makes tire inner high voltage gas leakage, reaches the effect that reduces tyre inner pressure; When tyre inner pressure dropped to preset pressure less than pressure spring, spool was realized sealing being pressed under the effect of pressure spring in the inferior part of the cylinder block outlet to cranked tire valve.
The present invention is simple in structure, and compact reliable, volume is little, and is lightweight; Utilize pressure reduction that spool is moved, do not have hysteresis, be swift in response, safe and reliable, applied widely.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to Fig. 1, present embodiment comprises cylinder body 2, is provided with spool 5 in the cylinder body 2, spool 5 tops are provided with the pressure spring 3 that places cylinder body 2 inside, have pressure relief opening 4 on cylinder body 2 sidewalls, pressure spring 3 tops are provided with regulating spring 1, and cylinder body 2 lower part outlets are connected with tire valve by tire tube valve connection pipe 6.
Described spool 5 is the I shape spool.
In and the situation greater than pressure spring 3 preset pressure too high at tyre inner pressure, spool 5 is backed down, and tire inner high voltage gas is delivered to pressure relief opening 4 places by tire tube valve connection pipe 6, get rid of to atmosphere through pressure relief opening 4,
Reach the effect that reduces tyre inner pressure; When tyre inner pressure dropped to preset pressure less than pressure spring 3, spool 5 had been pressed under the effect of regulating spring 1 pressure on cylinder body 2 lower part outlets, and tire valve is realized sealing.By regulating spring 1 can be in different situations the predetermincd tension of setting pressure spring 3.
In the situation too high to automotive tire pressure, release can be in time carried out in the application of the invention, tyre inner pressure is remained under the default maximum pressures of pressure spring 3, well eliminated in the situations such as outside tires excess Temperature, cause the too high and hidden danger of blasting of tyre inner pressure.
