Embodiment 1

[0030] In a comprehensive performance test of a dual-channel distribution valve, the details are as follows:

[0031] The first step is to turn on the air source 1, and the compressed air with a pressure of 0.8MPa passes through the pressure regulating table 5, and after the first round of the pressure value is stabilized at (0.15-0.4)MPa, it is stored in the air tank 3 and connected to the first pressure gauge 4-1 to test, the current pressure is 0.2MPa.

[0032] In the second step, the 0.2MPa compressed air after the first round of stabilization is sent to the second pressure regulating valve 2-2 through the pressure regulating table 5, and then the second round of pressure regulation is performed, and the second pressure gauge 4-2 is connected for detection. The current pressure It is 0.124MPa, and the pressure value is stable in the range of (0.121-0.158)MPa. Open the on-off valve 6, send the compressed air to the dual-channel distribution valve 9, connect the flow meter 7...

Abstract

The invention belongs to the technical field of valve performance testing, and relates to a device for testing the comprehensive performance of a dual-channel distribution valve. The device is composed of a gas source (1), a pressure regulating table (5), a second pressure regulating valve (2-2), a second pressure gauge (4-2), a third pressure gauge (4-3), a fourth pressure gauge (4-4), a switch valve (6), a flow meter (7), a test box (10), a power supply (11), a vacuum device (12), an oscilloscope (13), a first deicing sleeve (14-1) and a second deicing sleeve (14-2). The testing method is simple in operation, the used comprehensive performance testing system is simple in configuration, the detection capability of the comprehensive performance of the dual-channel distribution valve can be effectively realized, the detection capability comprises pressure, flow and vacuum degree, the internal pressure switch signals of the dual-channel distribution valve are acquired, the technical indexes of the dual-channel distribution valve are ensured to meet the requirements, and the test is reliable and stable.

Description

technical field [0001] The invention belongs to the technical field of valve performance testing, and relates to a comprehensive performance testing device and method for a dual-channel distribution valve. Background technique [0002] The dual-channel distribution valve is a component of the aircraft airbag deicing system, and is crucial to the safe operation of the airbag deicing system. Since the dual-channel distribution valve is an imported product, there is no effective performance testing method in the past work. In order to effectively verify the performance of the dual-channel distribution valve, ground test verification must be carried out. The comprehensive performance test of the dual-channel distribution valve is realized by detecting the pressure and flow rate, vacuum degree and pressure switch setting value during inflation. Contents of the invention [0003] The object of the present invention is: to provide a dual-channel distribution valve comprehensive ...
