The most key important component of peace system, in view of its critical importance, security reliability should attract great attention.
But current original crisis warning system has the following deficiencies: can only test single AST solenoid valve online, and original system is set
In meter, four AST solenoid valves can only individually be made in thread test, can not series, parallel experiment.And when testing, two can only be passed through
ASP pressure switch determines whether solenoid valve is working properly, and AST solenoid valve, integrated block assembly can not be isolated, on-bne repair unit
In normal course of operation, if it find that the component on AST solenoid valve, integrated block assembly can not work normally, external leakage has
The problems such as, it can only work, cannot be isolated, on-line maintenance " in spite of illness ".Shutdown could be handled hidden after unit needs application to reduce load
Suffer from, once causing " non-to stop ", will cause very huge economic loss, be unfavorable for the long-term safety stable operation of unit.It can not be real-time
ASP pressure is monitored, former emergency trip device is equipped with ASP pressure monitoring point among four series-parallel AST electromagnetism valve positions, but makes
It is two pressure switches, can only whether working properly as four solenoid valves of qualitative analysis.
