Abstract
The utility model belongs to a tyre explosion-resistant device, particularly an explosion-resistant tyre valve which is characterized in that the explosion-resistant tyre valve is a T-piece structure tyre valve which is formed by a connection port which can be arranged on an original tyre, an air inlet arranged on one end, and an air outlet arranged on another end; the pressurization value of the air outlet can be adjusted; the end of the air outlet is provided with an air whistle which can warn. The utility model has the advantages of tyre burst prevention, simple structure and convenient installation.
Description
The utility model belongs to the tire explosion protection.Be particularly related to a kind of valve.
The present air faucet of tire of generally using generally all comprises detouchable valve inside part in the valve that is connected on the tire and the valve, because what adopt is unidirectional air admission type valve, can only air inlet, and can not give vent to anger automatically.When tire is subjected to external factor (as: temperature build-up, heavy duty etc.) when influencing, perhaps tire year aging for a long time, when gaseous tension surpasses the tire ability to bear in the tire, will blow out, work the mischief.
The purpose of this utility model provides a kind of runflat valve that can reduce gaseous tension in the tire automatically.
The technical solution of the utility model is: increase the passage that can give vent to anger automatically at tire Primordial Qi mouth portion, and condition of service according to tire, can adjust the withstand voltage of gas port, when giving vent to anger automatically, the ring siren at air extractor duct place, report to the police to driver and crew, it is characterized in that bringing out the valve of " three way type " structure that gas port and an end communication port constitute by an end admission port,, be installed in the original valve of tire, replace the valve inside in the former valve, valve inside is installed in the admission port in the former tire, constitutes induction part jointly with admission port.Air extractor duct and setting nut, pressure-bearing spring, piston, packing seal have been formed the outlet gas part of scalable withstand voltage, and a siren is equipped with at the air extractor duct place.
The utility model has the advantages that: pre-runflat, simple in structure, easy for installation.Valve inside in original air faucet of tire is pulled down, be installed in the admission port, communication port is installed in original air faucet of tire, regulate the setting nut at top, configure the maximum pressure value that needs tire to bear.When the tire internal pressure increased to force value above this setting, gas was discharged from air extractor duct immediately automatically in the tire, and reaching the effect of runflat, and the siren of ringing is automatically reported to the police to driver and crew.On the setting nut at this valve top and the valve top portion do not indicate the scale of corresponding expression withstand voltage, reference when being convenient to chaufeur according to the actual condition of service setting nut of tire.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1 is the cutaway view of an embodiment of the utility model runflat valve.
As shown in Figure 1, the utility model runflat valve is by admission port 1, the three links formula structure that air extractor duct 3 communication ports 2 are formed, there is a circle seal ring 4 at the communication port place, communication port is fixed in the former valve of tire, valve inside in the former valve is pulled down in the admission port of packing into, one siren 7 is arranged at the air extractor duct place, whether give vent to anger in order to remind driver and crew's tire, runflat valve top is a setting nut 10, and indicate and the corresponding scale in valve top, according to the actual conditions that tire uses, set the maxim that valve need bear pressure, regulate the elasticity of setting nut control pressure-bearing spring 9, pressure-bearing spring pressing piston 8 and underpiston packing seal 11, when Tyre inflating, gas is from admission port 1 process valve inside, induction opening 5, communication port 2 enters in the tire, when gaseous tension in the tire surpasses the maximum withstand voltage of setting in advance, through communication port 2, through air gate 6 air extractor ducts 3 automatically discharge and the siren 7 at ring air extractor duct place again in the tire by jack-up piston 8 and piston gasket 11 for gas.
Claims (2)
1. runflat valve, comprise valve and the valve inside part that is installed in the valve, it is characterized in that described runflat valve by admission port 1, communication port 2, the three links formula structure that air extractor duct 3 is formed, communication port is contained in the former valve of tire, and original valve inside is pulled down air extractor duct and pressure-bearing spring 9 are installed in the admission port in the tire, piston 8 packing seals 11, air gate 6 constitutes outlet passageway, and the pressure-bearing spring is regulated elasticity by setting nut 10, in order to set the required pressure that bears of runflat valve; Setting nut and runflat valve top indicate the scale of corresponding withstand voltage.
2. according to the runflat valve of claim 1, it is characterized in that the air extractor duct place is equipped with a siren 7.
