Automatic inflation device for aircraft tire

Abstract

The invention relates to an automatic inflation device for an aircraft tire. The automatic inflation device comprises a main pipeline, a controller and an electric source connected with the controller, wherein an air source connector is arranged at one end of the main pipeline and an inflation connector is arranged at the other end of the main pipeline; and an air source pressure gauge, a pressure reducer, an inflation pressure regulating valve, an inflation solenoid valve, a pressure-measuring pressure gauge, a pressure transmitter and a deflation solenoid valve are arranged sequentially on the main pipeline in the direction from the end with the air source connector, of the main pipeline, to the end with the inflation connector, of the main pipeline, and the inflation pressure regulating valve, the inflation solenoid valve, the pressure transmitter and the deflation solenoid valve are electrically connected with the controller. The automatic inflation device of an aircraft tire provided by the invention is simple in structure and convenient in operation; repeated inflation and deflation as well as pressure testing are not needed; inflation can be automatically completed simply by connecting the pipeline; the pressure displayed by the pressure-measuring pressure gauge is the current tire pressure; and inflation is accurate and safe.

Description

technical field [0001] The invention belongs to the technical field of aircraft tire inflation, and relates to an aircraft tire inflation device, in particular to an aircraft tire automatic inflation device. Background technique [0002] At present, most of the aircraft tire inflation devices used by aviation aircraft use manual inflators. The outfield aircraft tire inflation work is mainly for air pressure monitoring and air replenishment, and the actual air consumption is not large. If there is a large air leak in the tire, the tire will be replaced. [0003] The existing aircraft tire inflation device generally consists of three gas cylinders plus several valves and pressure gauges to form an inflatable car, which requires a tool cart to be mounted and towed when moving, or 2-3 people to complete the moving process; the inflation operation It requires the cooperation of multiple people and multiple steps to complete the operation. During the inflation process, the operat...

AI Technical Summary

Problems solved by technology

Manual inflation is aimed at a single tire, relying on the experience of the operator to manually inflate one by one, the tire pressure cannot be given accurately, therefore, it is impossible to ensure that the pressure of each group of tires is consistent

[0005] It can be seen from the above that the existing aircraft tire inflation device can no longer meet the requirements of fast, safe, and maneuverable guarantees, and there is an urgent need for a tire inflation device that can safely, quantitatively, accurately automatically inflate and deflate aircraft tires, and accurately monitor tire pressure.
