Abstract
A tire inflation tool comprises a pressure regulating valve, a safety valve, a shutoff valve and a deflation valve, wherein the pressure regulating valve and the safety valve are sequentially connected through a high-pressure air pipe; the air inlet end of the pressure regulating valve is connected with a high-pressure gauge, and the air outlet end of the pressure regulating valve is connected with a low-pressure gauge I; and a second low-pressure gauge is connected to the high-pressure air pipe on one side of the air release valve. Compared with the prior art, the utility model discloses a tire inflation instrument inflates the atmospheric pressure of in-process through each manometer real time monitoring, avoids under the traditional mode earlier aerifing the complicated work that the back detected, has promoted work efficiency, has avoided the equipment damage problem because of change instrument leads to many times moreover.
Description
Technical Field
The utility model relates to an aircraft ground maintenance equipment field specifically indicates a tire inflation instrument.
Background
The tire inflation instrument is the instrument that uses in the tire maintenance, and at present, the inflation instrument that uses behind the aircraft tire maintenance mostly is single instrument, can only inflate, can not measure, need pull down the tire pressure table for the inflation instrument and measure, and the inflation process can't be monitored, and reciprocal change instrument inefficiency causes the inflation valve damage of inflation instrument more easily.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, and provide a tire inflation instrument.
In order to solve the technical problem, the utility model discloses a technical scheme is:
a tire inflation tool comprises a pressure regulating valve, a safety valve, a shutoff valve and a deflation valve, wherein the pressure regulating valve and the safety valve are sequentially connected through a high-pressure air pipe; the air inlet end of the pressure regulating valve is connected with a high-pressure gauge, and the air outlet end of the pressure regulating valve is connected with a low-pressure gauge I; and a second low-pressure gauge is connected to the high-pressure air pipe on one side of the air release valve.
Furthermore, the tail end of the high-pressure air pipe is connected with a quick-release connector.
Furthermore, the pressure range of the high-pressure gauge is 0-25 Mpa.
Furthermore, the range of the first low-pressure gauge and the second low-pressure gauge is 0-2.5 Mpa.
Compared with the prior art, the utility model discloses a tire inflation instrument inflates the atmospheric pressure of in-process through each manometer real time monitoring, avoids under the traditional mode earlier aerifing the complicated work that the back detected, has promoted work efficiency, has avoided the equipment damage problem because of change instrument leads to many times moreover.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
the pressure regulating valve comprises a pressure regulating valve 1, a safety valve 2, a safety valve 3, a shutoff valve 4, an air release valve 5, a quick release connector 6, a high-pressure gauge 7, a first low-pressure gauge 8 and a second low-pressure gauge 8.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in figure 1, the tire inflation tool comprises a pressure regulating valve 1, a safety valve 2, a shutoff valve 3 and a deflation valve 4, wherein the pressure regulating valve 1, the safety valve 2, the shutoff valve and the deflation valve 3 are sequentially connected through a high-pressure air pipe, the inlet end of the high-pressure air pipe is connected with a nitrogen cylinder, the tail end of the high-pressure air pipe is connected with a quick-release connector 5, and the quick-release connector 5 is used for being connected with a tire to be inflated.
The air inlet end of the pressure regulating valve 1 is connected with a high-pressure gauge 6, and the air outlet end of the pressure regulating valve 1 is connected with a low-pressure gauge I7; and a second low-pressure gauge 8 is connected to the high-pressure air pipe on one side of the air release valve 4.
In the embodiment, the high-pressure gauge 6 is a mechanical pressure gauge of Shanghai pressure reducer factory, Ltd, and the measuring range is 0-25 Mpa; the first low-pressure gauge 7 and the second low-pressure gauge 8 are mechanical pressure gauges of Shanghai pressure reducer factory Limited, and the measuring range is 0-2.5 Mpa.
The working principle is as follows: after the tire is assembled, connecting the tire inflation tool with a nitrogen gas source, confirming that the shutoff valve 3 is closed, connecting the quick release connector 5 with the tire inflation inlet, and opening the gas source valve; whether the residual air pressure of an air source meets the tire inflation requirement is confirmed by observing the high-pressure gauge 6, the pressure regulating valve 1 is adjusted, whether the inlet air pressure meets the inflation requirement is confirmed by observing the first low-pressure gauge 7, and if the pressure is overlarge, the air is discharged through the safety valve 2; slowly opening the shut-off valve 3, observing whether the numerical value of the second low-pressure gauge 8 reaches the inflation standard, closing the shut-off valve 3 when the pressure reaches the inflation standard, and opening the deflation valve 4 to deflate if the pressure in the tire is overlarge.
The present invention is not limited to the above-described embodiments, and those skilled in the art can make modifications or changes without departing from the spirit of the present invention.
