The utility model content: the purpose of this utility model is to provide a kind of lighter valve non-adjusting current limiter device for overcoming the deficiencies in the prior art, this non-adjusting current limiter device can with the direct adapted of existing air valve, gas tank also need not to change.
For achieving the above object, the utility model adopts following technical scheme: a kind of lighter valve non-adjusting current limiter device, it is characterized in that: described non-adjusting current limiter device comprises filter air film and two packing rings that are clipped in the passage that is provided with the regulation breathing area on filter air film both sides respectively, and washer outer diameter and nipple internal diameter are suitable.
As further setting of the present utility model: the passage contour shape of described packing ring is the geometric figure of rule, and the passage of described packing ring can be made of two or more through holes.
Further be provided with as of the present utility model: described packing ring one side end face is provided with cavity, and the center is provided with thin through hole at the bottom of the cavity, and two packing ring cavitys are relative again.
Further be provided with as of the present utility model: the passage shape of described packing ring has the sagging structure of anti-filter air film, and the sagging structure of described anti-filter air film can be to become radial passage to constitute by profile; Also can be to become the passage of " worker " shape to constitute by profile; Can also be by on packing ring one side end face cavity being set, the center be provided with thin through hole at the bottom of the cavity, and it is that the radial groove in center constitutes that described cavity bottom surface is provided with thin through hole.
Compared with prior art, the washer outer diameter and the nipple of non-adjusting current limiter device are suitable, can directly place the nipple on the existing gas tank gas outlet, screwing in existing air valve assembly then compresses, the throughput of non-adjusting current limiter device is only relevant with the area of packing ring central through hole, when the area of packing ring central through hole is constant, throughput also just remains unchanged, the flare height also just remains unchanged equally, reached purpose with the direct adapted of existing air valve, also help the former workman of class assembling, be more convenient for applying.
The utility model is described in further detail below in conjunction with accompanying drawing, and provide specific embodiment.
