Abstract
The utility model relates to a valve of an automobile tire, particularly an anti-explosion device for an automobile tire, which is connected with the valve of the automobile tire. The anti-explosion device for an automobile tire is characterized in that a back hoop (1) and a housing body (2) are in thread connection, and a front hoop (9) and the vale of the automobile tire are in thread connection. A pneumatic spring (3) is sheathed on a conical top pad (4), a rubber pad (6) is arranged between the conical top pad (4) and a thimble (8), and an annular rubber pad (7) is sheathed on the thimble (8). The utility model has the advantages of simple structure, low cost, safe operation and use and convenient maintenance.
Description
The utility model relates to the motor tire valve nozzle, is specially the motor tire explosion protection that the motor tire valve nozzle is connected.
At present motor tire is when inflation, do not noted filling as operating personal many, the then direct explosion of tire, or summer when temperature is too high, tyre inner pressure increases, and during then above tire pressure, just produces explosion.Existing technology is the object of filling foam and so in motor tire.
It is a kind of when the motor tire internal pressure reaches or be near the mark pressure that the purpose of this utility model is to provide, and the meeting automatic deflation makes the interior pressure of tire be less than or equal to the motor tire explosion protection of tire standards pressure forever.
The purpose of this utility model is achieved in that back hoop (1) is to be threaded with housing (2), preceding hoop (9) is to be threaded with the motor tire valve, gas spring (3) is enclosed within on the taper top pad (4), is enclosed within on the thimble (8) for rubber cushion (6), annular rubber cushion (7) between taper top pad (4) and thimble (8).
Advantage of the present utility model is: simple in structure, with low cost, and operation, safe and reliable, easy to maintenance.
Fig. 1 is the utility model structural principle generalized section.
Below in conjunction with accompanying drawing in detail the utility model most preferred embodiment is described in detail: back hoop (1) is to be threaded with housing (2), preceding hoop (9) is to be threaded with the motor tire valve, gas spring (3) is enclosed within on the taper top pad (4), is enclosed within on the thimble (8) for rubber cushion (6), annular rubber cushion (7) between taper top pad (4) and thimble (8).The anticyclonic pressure that for example motor tire bore is 8MPa, we set the explosion-proof air pressure of the utility model is 7.5MPa, after motor tire pumps enough air in, the utility model is screwed on the valve of tire by preceding hoop (9), annular rubber cushion (7) then sticks together tightly with motor tire valve edge, thimble (8) withstands the air tube of motor tire, make the air pressure in the utility model air chamber (10) identical with the motor tire internal gas pressure, when automobile surpasses 7.5MPa, gas spring (3) will shrink and move, simultaneously, be subjected to gas pressure, taper top pad (4) and rubber cushion (6) also move in the meeting, and then gas will pass through air leakage hole (5) discharge, makes the motor tire internal gas pressure remain 7.5MPa.Back hoop (1) can be turned on, and according to different automobiles, changes the spring of different pressures.
Claims (1)
1, a kind of motor tire explosion protection, it is to be made of back hoop (1), housing (2), gas spring (3), taper top pad (4), air leakage hole (5), rubber cushion (6), annular rubber cushion (7), thimble (8), preceding hoop (9), it is characterized in that: back hoop (1) is to be threaded with housing (2), preceding hoop (9) is to be threaded with the motor tire valve, gas spring (3) is enclosed within on the taper top pad (4), is enclosed within on the thimble (8) for rubber cushion (6), annular rubber cushion (7) between taper top pad (4) and thimble (8).
