A test device for ultra-high pressure extrusion servo system

Abstract

The invention provides a testing device of an ultrahigh-pressure extrusion type servo system. The testing device comprises an equivalent simulation pipeline, wherein the equivalent simulation pipeline is in parallel connection with two ends of an electric explosion valve of the ultrahigh-pressure extrusion type servo system; one end of the equivalent simulation pipeline is connected with an air charging connector, and the other end of the equivalent simulation pipeline is connected with an on-line testing port of a pressure reducing valve; and the equivalent simulation pipeline is used for simulating the electric explosion valve equivalently, so that a test on the high-pressure extrusion property of a high-pressure helium gas source is carried out. According to the testing device of the ultrahigh-pressure extrusion type servo system, in a state that the high-pressure helium gas source is equipped with the electric explosion valve, the high-pressure helium gas extrusion test is carried out through the testing device which is in parallel connection with two ends of the electric explosion valve; both the pressure-bearing property and the sealing property of the electric explosion valve are checked; and high testing coverage of the ground test is realized.

Description

technical field [0001] The invention relates to the test field of a rocket servo system, in particular to a test device for an ultra-high pressure extrusion servo system. Background technique [0002] The ultra-high pressure extrusion servo system is an indispensable key single machine of the rocket servo system, and its working power is the most powerful except the rocket engine. Its working characteristics play a decisive role in the attitude control of the servo system and even the whole rocket. When the rocket is flying, the electric explosion valve on the high-pressure helium source of the servo system is detonated by the electric explosion tube, and the cutter in the electric explosion valve is pushed to cut off the partition to form a helium passage, and the high-pressure helium (60MPa) stored in the high-pressure helium source is thus The passage reaches the pressure reducing valve, and after being decompressed by the pressure reducing valve (24MPa), it is applied t...
