Description
Technical field
The utility model relates to a kind of cooperation to the valve inside of tyre inflating, espespecially a kind of porous air pressure valve.
Background technique
For pneumatic tire, all need to arrange valve inside (or claiming air pressure valve), the effect of valve inside is to coordinate air pump that tire is inflated, and valve is blocked in case leak-stopping gas after inflation.Because existing inside tires only has a cavity, the air pressure valve that therefore coordinates with it also only has a vent.Yet this case inventor has designed a tire (separate case application) with a plurality of separate air-pressure chambers, to inflate each air-pressure chamber, use existing air pressure valve obviously can not realize, a plurality of air pressure valves are inconvenient, the unrealistic while is also uneconomical and will use.Therefore how can simultaneously a plurality of air-pressure chambers be inflated or exit, each air-pressure chamber not communicated and separate, be the problem that this case need to solve.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of and can inflates or exit a plurality of air-pressure chambers simultaneously, and makes again the separate porous air pressure valve of each air-pressure chamber after inflation.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of porous air pressure valve comprises valve body, gas shutoff bolt and air entraining valve assembly; This valve inner is provided with cavity, and the sidewall of this cavity has at least two vents; This gas shutoff bolt is arranged on valve body, and it is provided with, and a tightening latch is slotting stretches in described inside cavity, and the inner surface contour of the exterior contour of this tightening latch and this cavity is suitable, and this tightening latch is provided with air flue and air flue outlet; This air entraining valve assembly is arranged on the air flue inlet end of this gas shutoff bolt, is provided with check valve structure in it.
The end of described tightening latch and the inner of described cavity are the taper that cooperatively interacts.
Described tightening latch is provided with outside thread and the screw-internal thread fit that is arranged on described valve body cavity, thereby described gas shutoff bolt is arranged on described valve body.
Described tightening latch is provided with a bolt head that facilitates rotary manipulation.
Be equipped with one on described each vent in order to the joint of flexible pipe to be installed.
The outside spiral of described valve body has a set screw nut.
After adopting such scheme, offered a plurality of vents due to the utility model on the valve body of described air pressure valve, and be provided with can each vent of shutoff the gas shutoff bolt, and each vent can be connected with the air-pressure chamber of a wish inflation.When inflation, unscrew the gas shutoff bolt, open each vent, can realize each air-pressure chamber is inflated simultaneously; When screwing the gas shutoff bolt, can close each vent, like this, each air-pressure chamber just can not be interconnected by air pressure valve, thereby makes each air-pressure chamber become chamber separate and sealing.When this air pressure valve being applied to have on the tire of many air-pressure chambers, can realize that an air pressure valve simultaneously to a plurality of air-pressure chambers inflations or venting, can prevent that again each air-pressure chamber is connected by this air pressure valve after inflation, guarantee the use safety of tire.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
What the utility model disclosed is a kind of porous air pressure valve, as shown in Figure 1, 2, is preferred embodiment of the present utility model.Described porous air pressure valve comprises valve body 1, gas shutoff bolt 2 and air entraining valve assembly 3, wherein:
Described valve body 1 inside is provided with the cavity 11 of hollow, and the sidewall of this cavity 11 has at least two vents 12, a joint 13 can be installed in order to the convenient flexible pipe of installing on each vent 12.
Described gas shutoff bolt 2 is arranged on described valve body 1, and it is provided with a tightening latch 21 and inserts cavity 11 inside that stretch in valve body 1, and the inner surface contour of the exterior contour of this tightening latch 21 and described cavity 11 is suitable, and this tightening latch 21 is provided with air flue 22 and air flue outlet 23.Further, outside thread 24 can be set on this tightening latch 21 coordinate with internal thread 14 on the cavity 11 that is arranged on valve body 1, thereby described gas shutoff bolt 2 is arranged on described valve body 1.The inner of the end of described tightening latch 21 and described cavity 11 can be the taper that cooperatively interacts, thereby when tightening latch 21 screws in mutually, can guarantee closely cooperating of tightening latch 21 and cavity 11.On described tightening latch 21, a bolt head 25 can also be set, to facilitate the rotary manipulation of gas shutoff bolt 2.
Described air entraining valve assembly 3 is arranged on air flue 22 inlet ends of described gas shutoff bolt 2, and this air entraining valve assembly 3 generally is similar to existing valve inside, and its inside is provided with check valve structure, and this air entraining valve assembly 3 is not this case emphasis, is not described in detail its structure at this.
In addition, spiral is gone back in the outside of described valve body 1 set screw nut 4, described air pressure valve can be arranged on tire by this set screw nut 4.
Described air pressure valve in use, it is arranged on tire 9, and as shown in Figure 3, each communicates by an interior air-pressure chamber 91 of hole 12 and tire 9, can be connected on described joint 13 by flexible pipe 8, then the other end of flexible pipe 8 is plugged on the pore 92 of air-pressure chamber 91.When wish during to tyre inflating, as shown in Figure 4, the gas shutoff bolt 2 of air pressure valve is unscrewed, each vent 12 of valve body 1 is opened, then lived air entraining valve assembly 3 and inflate, just can realize the purpose of simultaneously all air-pressure chambers 91 of tire being inflated, simple to operate, quick.When the air pressure in tire is enough; inwardly screw gas shutoff bolt 2; the tightening latch 21 of gas shutoff bolt 2 and cavity 11 sidewalls of valve body 1 are fitted tightly; each vent 12 is blocked; like this; each air-pressure chamber 91 of tire 9 just can not be interconnected by air pressure valve; make each air-pressure chamber 91 form separate and airtight chamber; when vehicle in the process of moving; when the sharp thing of prominent chance will be taken turns puncture, only have the air-pressure chamber gas leakage of breakage spot, and can not affect the air pressure of other air-pressure chambers; thereby the safety traffic of support vehicles, protection vehicle crew safety.When wanting re-type, the gas shutoff bolt 2 with described porous air pressure valve unclamps equally, and each air-pressure chamber 91 of tire will be exitted simultaneously by this air pressure valve, and is easy to operate.
The above is only preferred embodiment of the present utility model, is not to limit the scope that the utility model is implemented.Therefore variation or the modification in every case done according to claim of the present utility model and specification are within all should belonging to the scope that the utility model patent contains.
