Abstract

The invention provides an electromagnetic valve automatic testing device for a spaceflight attitude and orbit control engine. The electromagnetic valve automatic testing device comprises a testing switching circuit, a conduction insulation testing circuit and a valve characteristic testing circuit. The input end of the test switching circuit is connected with a tested valve, the output end of the test switching circuit is respectively connected with the conduction insulation circuit and the valve characteristic test circuit, and the tested valve is singly connected with the conduction insulation test circuit or the valve characteristic test circuit. Compared with an existing testing method, the device has the advantages that the number of times of manually plugging and unplugging the testing plug is reduced, and the probability of manual operation errors is reduced.

Description

technical field [0001] The invention relates to the technical field of aerospace engines, in particular to an automatic testing device for solenoid valves used in aerospace attitude and orbit control engines. Background technique [0002] Mass production requirements of a certain type of missile: In order to meet batch testing, mass delivery, and rapid assembly, the attitude control engine system test must improve test efficiency to avoid damage to the attitude control engine system caused by human error, resulting in delays in production and delay in assembly. [0003] For the high-response solenoid valve test in the attitude control engine system test, it is first necessary to replace the valve characteristic test cable to complete the characteristic test after the conduction insulation test data of the valve is qualified. It takes a long time to replace the test cable. If the tester is unskilled, he may forget to replace the test cable and use the valve characteristic tes...
