Detailed Description
The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.
In order to achieve the above object, the present utility model provides the following embodiments:
as shown in fig. 1 to 4, an air spring inflating tool for a commercial vehicle comprises an air inlet unit, a pressure limiting unit and an air outlet unit; the air inlet unit, the pressure limiting unit and the air outlet unit are sequentially connected, the air inlet unit can be connected with an external air source, and the air outlet unit can be connected with an air spring inflation pipeline. The air inlet unit comprises an air inlet pipeline 1 and a separating switch 2, and the separating switch 2 is arranged on the air inlet pipeline 1; the pressure limiting unit comprises a pressure limiting valve 4; the gas outlet unit comprises a gas outlet connector 7.
The air outlet unit further comprises an air distribution connector 5, and an air inlet of the air distribution connector 5 is connected with an air outlet of the pressure limiting valve 4; the gas distribution joint 5 is at least three taps, and the gas outlet joint 7 is arranged on one joint of the gas distribution joint 5. The air outlet unit further comprises a water drain valve 6, and the water drain valve 6 is arranged on one joint of the air distribution joint 5.
The gas outlet unit further comprises a plug 8, and the plug 8 is arranged on an unused interface of the gas distribution joint 5. When other equipment needs to be connected, the plug 8 can be taken out, and when the equipment is not needed, the plug 8 is plugged so as to prevent air leakage.
The commercial car air spring inflating tool further comprises a reducing joint, and an air inlet of the pressure limiting valve is connected with the disconnecting switch through the reducing joint.
The air outlet joint 7 is a three-way joint. One end of the three-way joint is connected with the air inlet of the air distribution joint 5, and the other two ends of the three-way joint are used as air outlets and can be respectively connected with air spring inflation pipelines on the left side and the right side of the commercial vehicle.
The standard pressure of the pressure limiting valve is 0.4MPa so as to adapt to the air pressure required by the air spring.
Also comprises a fixing unit. The fixing unit comprises a U-shaped fixing support 9, one side of the fixing support 9 is fixed on the pressure limiting valve 4 through bolts and nuts, and the other side of the fixing support is fixed on a commercial vehicle frame through bolts and nuts.
