As Figure 1-4, the present invention includes hollow valve body 1, is arranged on the hollow valve body tube reducing group 3 of the one end of hollow valve body 1
With the depression bar 2 for being fixed in the other end of hollow valve body 1, the valve body that the hollow valve body tube reducing group 3 is sequentially reduced by internal diameter subtracts
Footpath sleeve composition, adjacent valve body tube reducing sleeve are connected through a screw thread, and valve body tube reducing sleeve is also hollow structure, the hollow valve
The maximum valve body tube reducing sleeve of internal diameter is connected through a screw thread with hollow valve body 1 in body tube reducing group 3, and the two of the valve body tube reducing sleeve
End is respectively arranged with internal thread and external screw thread, sets female side and the smaller valve body tube reducing sleeve connection of internal diameter, if
It is equipped with the externally threaded side valve body tube reducing sleeve bigger with internal diameter or hollow valve body 1 is connected.If valve body tube reducing sleeve has three,
Internal diameter is designated as tube reducing 1, tube reducing 2 and tube reducing 3, tube reducing 1, that is, one end of tube reducing 1 and is provided with external screw thread successively from big to small, in
Offside on empty valve body 1 positioned at depression bar 2 is provided with the internal thread being adapted with the bottom external screw thread of tube reducing 1, and the other end of tube reducing 1 is set
Internal thread is equipped with, is adapted with the external screw thread on tube reducing 2, the internal thread on the other end of tube reducing 2 is mutually fitted with the external screw thread on tube reducing 3
Match somebody with somebody, the gas-charging connection on internal thread and equipment on the other end of tube reducing 3 is connected through a screw thread.
The hollow valve body 1 is located at the side of depression bar 2 and is provided with external screw thread, passes through the external screw thread hollow valve body 1 and inflation
Device connects.Thus, by the transfer of hollow valve body 1, the gas-charging connection in the equipment of different bores is connected with aerating device.
In use, several valve body tube reducing sleeve sets, on hollow valve body 1, according to the bore of the gas-charging connection in equipment, selection is closed
Suitable valve body tube reducing sleeve, it is unnecessary only to back out, and convenient and swift, use range is wide, and the inflation solved in equipment connects
Head and the unmatched problem of aerating device joint.
Further, hollow valve body is additionally provided with the hollow valve body 1 and increases footpath group, the hollow valve body increases footpath group
It is located at the both ends of hollow valve body 1 respectively with depression bar 2, hollow valve body increases footpath group and subtracts big valve body diameter increasing sleeve cylinder group successively by internal diameter
Into adjacent valve body diameter increasing sleeve cylinder is connected through a screw thread, and the hollow valve body increases the valve body diameter increasing sleeve cylinder that internal diameter is minimum in the group of footpath
It is connected through a screw thread with hollow valve body 1.Further, the both ends of the valve body diameter increasing sleeve cylinder are respectively arranged with internal thread and outer spiral shell
Line, set the female side valve body diameter increasing sleeve cylinder smaller with internal diameter or hollow valve body 1 to be connected, be provided with externally threaded one
The side valve body diameter increasing sleeve cylinder bigger with internal diameter is connected.
Thus, by the transfer of hollow valve body 1, bore can be increased or decreased to what is matched with equipment gas-charging connection
Size, redundance are backed out, convenient and swift, and use range is wide.
Include tank body 4 with the supporting air accumulator of above-mentioned high-pressure aerated transition valve, the air accumulator present invention also offers a kind of
And air valve, the air valve include valve 5 and sealing device that is interior positioned at tank body 4 and being connected with valve 5 outside tank body 4, institute
The bottom that sealing device is connected to valve 5 is stated, the sealing device includes being fixed in tank body 4 and is provided with ventilation on four perisporiums
Through hole 6-1 seal sleeve 6, the sealing-plug 7 being arranged in seal sleeve 6 and it is fixed in sealing-plug 7 and the bottom of seal sleeve 6
Spring 8, the longitudinal section of the sealing-plug 7 is up-narrow and down-wide trapezoidal, the top of the seal sleeve 6 and the sealing-plug 7
It is adapted, the internal diameter of the valve 5 is more than the internal diameter at the most narrow place in the top of sealing-plug 7；
The internal diameter of the valve 5 is more than the diameter of the depression bar 2, and the external screw thread phase with hollow valve body 1 is provided with the valve 5
The internal thread of adaptation.Further, the hollow valve body 1 is located at the side of depression bar 2 and is provided with hollow branch sleeve, hollow branch sleeve

The external screw thread being adapted with valve 5 is set on hollow branch sleeve, in use, hollow branch sleeve is arranged on valve 5 i.e.
Can.
In use, according to the size for the gas-charging connection for treating charger, the valve body tube reducing in hollow valve body tube reducing group 3 is selected
Sleeve or hollow valve body increase the valve body diameter increasing sleeve cylinder in the group of footpath, and remainder is removed, and the depression bar 2 of hollow valve body 1 injects gas
In mouth 5, after valve 5 and hollow valve body 1 are threadably secured, because depression bar 2 drives sealing-plug 7 to move down, the high pressure in tank body 4
Gas flows to valve 5 by the ventilation through hole 6-1 of seal sleeve 6, so as to which gas in tank body 4 be delivered to by hollow valve body 1
Treat in charger, after the completion of inflation, hollow valve body 1 is backed out, during backing out, in the presence of the screen resilience of spring 8,
Sealing-plug 7 blocks the connected component between seal sleeve 6 and valve 5, because the longitudinal section of sealing-plug 7 is up-narrow and down-wide ladder
Shape, the top of the seal sleeve 6 is adapted with the sealing-plug 7, as illustrated, the gas in tank body 4 passes through through hole of ventilating
6-1 applies to sealing-plug 7 to be upwarded pressure, and such sealing-plug 7 is interference fitted, and makes the air seal in tank body.
The present invention can realize fast insert-pull and can bear the oil pressure of 30 atmospheric pressure, and sealing is good, it is necessary to be set
During standby inflation, sealing-plug 7 is pushed, airway open, realize reliable airtight guarantee when not in use.Pass through hollow valve body 1
Intermediary so that different gas-charging connections can be connected by hollow valve body 1 with air accumulator, substantially increase charging efficiency, solve quilt
The problem of charger joint and air accumulator are difficult to matching degree, it is easy to large-scale promotion.
