Abstract

The invention relates to a constant flow air supply device of an aircraft environment control test system and a control method, and belongs to the technical field of aircraft environment control system test design. The device comprises an air compressor, an air storage tank, an automatic regulating valve, a controller, a pressure sensor, a manual regulating valve and an environmental control test system, one end of the air compressor is connected with the air storage tank; the air storage tank is connected with the environmental control test system through a pipeline; an automatic regulating valve, a pressure sensor and a manual regulating valve are arranged on the pipeline; and the controller is respectively connected with the automatic regulating valve and the pressure sensor. Compared with an existing manual adjustment means, the constant flow air supply device for air supply of the aircraft environment control test system can achieve automatic flow adjustment, and manpower cost is saved.

Example Embodiment

[0019] Next, the technical solutions in the embodiments of the present invention will be described in connection with the drawings of the embodiments of the present invention, and it is understood that the described embodiments are merely the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the present invention without making creative labor premise.

[0020] A aircraft ring control system constant flow gas supply device including air compressor 1, gas storage tank 2, automatic regulating valve 3, controller 4, pressure sensor 5, manual regulating valve 6, and ring control system 7;

[0021] One end of the air compressor 1 is connected to the gas tank 2, and the gas storage tank 2 is connected to the ring control system 7;

[0022] Automatic adjustment valve 3, pressure sensor 5, and manual regulating valve 6 are provided on the pipeline;

[0023] The controller 4 is connected to the automatic adjustment valve 3 and the pressure sensor 5, respectively.

[0024] Further, there is compressed air in the gas storage tank 2.

[0025] Further, the pipeline is a gas supply line.

[0026] Aircraft ring control test system Control method for controlling flow gas supply device:

[0027] Compressed air in the gas storage tank 2 follows upstream of the consumption of the ring control system 5, the pressure is constantly fluctuating, thus changing the flow of gas to the downstream ring control system 5;

[0028] The controller 4 outputs the pressure value to the automatic adjustment valve 3 to the automatic adjustment valve 3 by the controller 4, the controller 4 outputs the pressure value preset in the controller 4, and controls the pressure downstream of the automatic adjustment valve 3 to the set pressure value.

[0029] Further, by adjusting the opening degree of the manual adjustment valve 6, the flow rate of the air supply to the downstream loop test system 5 is controlled to be constant.

[0030] Further, the flow rate of the gas supply of the ring control system varies with the fluctuation of the pressure in the gas storage tank 2.

[0031] In all the schemes mentioned above, the connection between the two components can be connected, bolts, and nuts, bonded, bolts, and nuts or other well-known connection methods according to the actual situation, and described herein not described herein Any, preferably, it is preferred to be welded, although the embodiments of the present invention have been shown and described, and those skilled in the art, it is understood that the principles and spirit of the present invention will be apparent to those skilled in the art. These embodiments can be made, modified, replaced, and modified, and the scope of the invention is defined by the appended claims and their equivalents.
