AI Technical Summary

Technical Problem

In existing high-pressure gas distribution station technologies, electric explosion valves and high-speed switching valves suffer from high operating costs, significant safety risks, slow response speeds, low accuracy in controlling pressure rise rates, and low levels of automation, making it difficult to meet the testing needs of high-end manufacturing and defense industries.

Method used

By replacing the electric explosion valve with a rupture disc, and combining it with a sonic nozzle and a remote monitoring and control unit, rapid deflation and precise pressurization of high-pressure gas can be achieved. Through remote control and closed-loop protection mechanisms, the safety and automation of the test are ensured.

Benefits of technology

It achieves millisecond-level rapid pressurization of high-pressure gas, with a wide adjustable range of pressurization rate and high pressure control accuracy, reducing usage costs and safety risks, and improving the automation level and operational safety of the test.

Abstract

The invention discloses a test method and system for a high-pressure section gas supply and distribution station. The method comprises the following steps: S1, preparation before test; s2, simulating and calculating test parameters; s3, pressurizing and storing an air source; s4, test personnel evacuate; and S5, carrying out a rapid pressurizing test. The rupture disk replaces a traditional electric explosion valve and a high-speed switch valve to achieve rapid explosion venting of high-pressure gas, supervision and storage limitation of initiating explosive devices is eliminated, the use cost and the safety risk are reduced, the requirement for rapid response of a test is met by means of the millisecond-level explosion venting characteristic of the rupture disk, the rupture disk and the sonic nozzle are mature in technology and free of action frequency limitation, and the test efficiency is improved. And meanwhile, by replacing sonic nozzles with different throat diameters and combining critical flow control and actual gas state equation accurate calculation, 0.1 MPa / ms to 35 MPa / ms wide-range pressure increasing rate adjustment is achieved, the pressure control precision is within + / -5%, and the device can adapt to tested objects with different free volumes.
