Abstract

The invention relates to a test device for the large-flow performance of an electrically adjusted valve, and a test method of the test device. The test device comprises an air source module, a pressure regulating module, a flow measuring module, an air heating module, a test bed and an exhaust module which are sequentially connected through pipelines; and pressure sensors and temperature sensors used for detecting an inlet and an outlet of the valve are arranged in the pipelines at the two ends of the test bed. The test device is high in adjusting precision, easy to implement, rapid to implement, easy to operate and convenient to maintain, can meet the test requirements of an electrically adjusted valve product, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of aviation equipment testing, in particular to a large-flow performance test device and a test method for an electric regulating valve. Background technique [0002] At present, to determine whether the performance of aviation accessories is qualified is mainly to conduct simulation performance tests on various aviation accessories. During the test, it is necessary to provide an air source that meets the pressure, flow, and temperature. At the same time, the test equipment must have control over the relevant temperature, pressure, and flow. And monitoring, some of the pneumatic valves have high temperature and large flow, which put forward requirements on the temperature resistance, pressure resistance and flow volume of the pressure source and test device. Because of the increase of temperature, the seals at normal temperature cannot meet the performance requirements. In terms of materials, common steel pi...
