Inflation and deflation connector of airplane gas cylinder

Abstract

The invention provides an inflation and deflation connector of an airplane gas cylinder. The inflation and deflation connector of the airplane gas cylinder comprises a connector body, an inlet pipe connector and an outlet pipe connector. The connector body is of a three-way pipe structure, wherein a port in the lower end of the connector body stretches into the gas cylinder and is connected with amouth of the gas cylinder in a sealed mode, and ports in the left and right ends of the connector body are separately connected with the inlet pipe connector and the outlet pipe connector in a sealedmode. A filter assembly and a valve assembly are separately arranged on gas paths through which an inner cavity of the connector body communicates with the inlet pipe connector and the outlet pipe connector.

Description

technical field [0001] The application relates to the design and manufacture technology of aircraft, in particular to an air filling and deflation joint of an aircraft gas cylinder. Background technique [0002] There are multiple sets of gas storage cylinders used to store gaseous media such as oxygen, nitrogen, and compressed air necessary for flight on the aircraft. There are charging and discharging joints on the gas cylinders, which are mainly used to connect the small-diameter air intake pipeline and exhaust pipeline that need to be disassembled frequently, so as to realize the connection between the ground and the air intake and exhaust air passages in flight. At present, during the use of the gas storage cylinders on the aircraft, because the mechanical impurities in the gas are easy to adhere to the gas storage cylinders and the gas pipelines, the traditional filling and deflation type gas storage cylinder connectors only serve to connect the gas pipelines. effect,...

AI Technical Summary

Problems solved by technology

At present, during the use of the gas storage cylinders on the aircraft, because the mechanical impurities in the gas are easy to adhere to the gas storage cylinders and the gas pipelines, the traditional filling and deflation type gas storage cylinder connectors only serve to connect the gas pipelines. effect, it is impossible to filter the gas in and out of the gas storage cylinder in real time, which seriously affects the service life of the gas storage cylinder and downstream system accessories; moreover, the traditional filling and deflation type gas storage cylinder connector needs to be equipped with additional filter components, resulting in The gas circuit structure of various gas storage cylinders on the aircraft is complex

At the same time, because there is often free water in the gas storage cylinder, when the gas storage cylinder rolls with the aircraft, the free water will sometimes block the air outlet, resulting in poor air supply.
