Problems solved by technology

Due to the large number of tests per day in the wind tunnel, the operation is intensive and error-prone
Therefore, it is necessary to design the control system jointly with the cut-off valve and the main pressure regulating valve, and design their operation in an automatic mode, which not only ensures the reliability of the test, but also improves the test efficiency and saves costs. Currently, the hypersonic wind tunnel There is no such automated control system

Abstract

The invention discloses a control system of a stop valve and a total pressure regulating valve in a hypersonic wind tunnel, wherein the stop valve and the total pressure regulating valve are sequentially arranged on a high pressure main air inlet pipeline. The control system includes a driving pipeline system and an electrical control system; the driving pipeline system comprises a gas pipeline and a hydraulic pipeline, wherein the gas pipeline is connected with the high pressure main air inlet pipeline so as to tap a high-pressure gas, so that the stop valve and the total pressure regulating valve can be driven to be opened or closed in a linkage manner, and the hydraulic pipeline is communicated with the oil cavity of the total pressure regulating valve, so that the downstream pressure of the total pressure regulating valve can be maintained stable through adjusting the pressure of the oil cavity; the electrical control system acquires pressure data on the gas pipeline and the hydraulic pipeline through using a controller, and controls the on-off of the driving pipeline system according to a preset mode so as to realize the automatic opening or closing of the stop valve and the total pressure, and realize a regulating function of the downstream pressure of the total pressure regulating valve.

Description

technical field [0001] The invention relates to a control system of a cut-off valve and a general pressure regulating valve, in particular to a control system for the switch of the cut-off valve on the high-pressure main air intake pipeline of a hypersonic wind tunnel and the post-pressure adjustment control of the main pressure regulating valve. Background technique [0002] On the high-pressure main air intake pipeline of a conventional hypersonic wind tunnel, a cut-off valve and a general pressure regulating valve are arranged in sequence. Shut-off valves are used to quickly open or close high-pressure air sources. The main pressure regulating valve is used to adjust and stabilize the pressure behind the valve, and decompress the high-pressure main air intake, so as to ensure the stable flow of the secondary pressure regulating valve after the main pressure regulating valve, and high pressure adjustment accuracy after the valve. In the control system of the previous hype...
