Abstract
The utility model provides a tire anti-explosion device capable of automatically releasing the pressure of a tire. The tire anti-explosion device comprises a cylinder body, wherein the cylinder body is internally provided with a valve core, the upper part of the valve core is provided with a pressure spring arranged in the cylinder body, a pressure releasing opening is arranged on the side wall of the cylinder body, the upper part of the pressure spring is provided with an adjusting spring, and an outlet arranged at the lower part of the cylinder body is connected with a tire cycle valve by a cycle valve connecting pipe. The tire anti-explosion device is simple in structure, compact, reliable, small in volume, and light in weight; and the valve core can move due to the pressure difference, so that the tire anti-explosion device is free from lag, quick in reaction, safe and reliable, and wide in application range.
Description
Technical field
The utility model relate to a kind of can be automatically to the explosion-protection equipment of tyre of tire release.
Background technique
At present, in order to prevent tyre explosion, existing multiple explosion-protection equipment of tyre on the market: such as the tire pressure monitoring flameproof apparatus.Part tire pressure monitoring flameproof apparatus 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 component occur aging or loosening, trigger alarm timely just often; And in the situation that 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.
The model utility content
The technical problems to be solved in the utility model is, overcomes the defects that prior art exists, and provides a kind of functional reliability good, Safety performance is high can be automatically to the explosion-protection equipment of tyre of tire release.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of can be automatically to the explosion-protection equipment of tyre of tire release, 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 Regulation spring, and the inferior part of the cylinder block outlet is connected with tyre valve by the valve cock connecting tube.
Further, the preferred I shape spool of described spool.
The utility model is by the spool of common one-way valve in the similar hydraulic 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 utility model 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 utility model one embodiment's structural representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1, the 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 Regulation spring 1, and cylinder body 2 lower exits are connected with tyre valve by valve cock connecting tube 6.
Described spool 5 is the I shape spool.
In the situation that tyre inner pressure is too high and greater than pressure spring 3 preset pressure, spool 5 is backed down, tire inner high voltage gas is delivered to pressure relief opening 4 places by valve cock connecting tube 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 Regulation spring 1 pressure on cylinder body 2 lower exits, and tyre valve is realized sealing.Can be in the situation that the pretightening force of different setting pressure springs 3 by Regulation spring 1.
In the situation that too high to automotive tire pressure, by using the utility model can in time carry out release, tyre inner pressure is remained under the pressure spring 3 default pressure maximums, well eliminated in the situations such as outside tires excess Temperature, caused the too high and hidden danger of blasting of tyre inner pressure.
Claims (2)
- One kind can be automatically to the explosion-protection equipment of tyre of tire release, it is characterized in that, 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 Regulation spring, and the inferior part of the cylinder block outlet is connected with tyre valve by the valve cock connecting tube.
- 2. according to claim 1 can it is characterized in that automatically to the explosion-protection equipment of tyre of tire release, described spool is the I shape spool.
