Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with the technology of the present invention side
Implemented premised on case, give detailed embodiment and specific operating process, but the protection model of the present invention
Enclose and be not limited to following embodiments.
Embodiment
As shown in figure 1, a kind of high reliability nitrogen gas generator drainage system, including drain solenoid valve 1 and PLC
Controller 2, drain solenoid valve 1 are arranged on the drainage pipeline of nitrogen gas generator and are connected with PLC 2,
Drain solenoid valve 1 and PLC 2 form timing drainage magnetic valve, drainage system also include microcontroller 3,
Alarm 4, first pressure sensor 51 and second pressure sensor 52, the discharge outlet of nitrogen gas generator, first
Pressure sensor 51, drain solenoid valve 1 and second pressure sensor 52 are sequentially connected, microcontroller 3 respectively with
Alarm 4, first pressure sensor 51 and second pressure sensor 52 connect.
When 1 normal work of drain solenoid valve, the hydraulic pressure in drainage pipeline everywhere should be consistent, when the first pressure
When the hydraulic pressure value that force snesor 51 and second pressure sensor 52 detect differs by more than setting value, draining can determine whether
Magnetic valve 1 fails, or has blocking in pipeline, and now microcontroller 3 makes alarm 4 alarm in the first manner,
Remind faulty in operating personnel's pipe.
Drainage system also includes the leve monitor 6 being arranged on the drainage pipeline of nitrogen gas generator, leve monitor
6 positions are higher than drain solenoid valve 1, and are connected with microcontroller 3.Under normal circumstances, should not in drainage pipeline
There is too many ponding.When drain solenoid valve is unable to proper drainage, and microcontroller 3 and two pressure sensors are not yet
When detecting pressure anomaly, leve monitor 6 can be made up, i.e., when leve monitor 6 detects that water level exceedes
During setting value, now pipe internal water accumulation has reached dangerous values, and leve monitor 6 sends alarm signal to microcontroller 3
Number, control alarm 4 is alarmed in the second after microcontroller 3 receives signal, is reminded at operating personnel
Reason.Because the drainage pipeline of nitrogen gas generator is provided with hand-operated valve 7, the position of hand-operated valve 7 is less than leve monitor 6,
When operating personnel notice the alarm of the second way, then operable hand-operated valve 7, by the ponding in drainage pipeline
Discharge manually, the normal operation of nitrogen gas generator is not influenceed, reduce shutdown loss.
