Background technique
Sodium ion is one of the index that emphasis monitors in the water chemistry monitor system of power station, certain nuclear power station make up water treatment system
It needs to be monitored Na ion concentration, to guarantee that the water quality indicator for process system is met the requirements.Existing make-up water preparation
System uses intermittent duty mode, carries out water processed or stoppage in transit according to unit demand.When water manufacturing system is stopped transport, one side sample introduction stream
Great changes have taken place when amount relatively operates normally, and instrument measurement numerical value also correspondingly generates relatively large deviation；On the other hand, instrument measurement cup
Interior liquid level is insufficient, and under air pump purging, sodium ion electrode surface is in alternation of wetting and drying variable condition, causes measured value to have larger
Fluctuation, more than the alarm limits of instrument, is frequent in master control room monitoring screen and outranges alarm.And in system shutdown state
Under, such no practical significance of alarm, the alarm frequently occurred can influence in master control ASD picture brush screen instead and interference manipulates
The normal monitoring of member and operation.If move back fortune instrument manually, but there are the response time slow (move back fortune and come into operation not in time), put into operation just
The too long problem of phase instrument unavailable time.Therefore it is above-mentioned for solving to need to design a modified sodium table status monitoring device
Problem.
Summary of the invention
Object of the present invention is to provide a kind of sodium table status monitoring device and its operation side in view of the above shortcomings of the prior art

The technical issues of warning message.
The technical scheme is that
A kind of sodium table status monitoring device, comprising: sampling valve is connected with other valve, flowmeter and calibration in turn from the bottom to top
Valve；The calibration valve is connect with diffuser, and is arranged in alkalizing agent bottle；Alkalizing agent bottle connects measuring cup；Measuring cup connects
Transmitter is connect, the transmitter is also connected with air pump and overflow cup；The overflow cup, measuring cup connect with catch basin respectively
It connects；The other valve is connect with overflow cup.
Measuring electrode, reference electrode and temperature electrode are respectively arranged in measuring cup as described above.
Liquid-level switch, liquid-level switch contact, slide bar and magnetic float are additionally provided in overflow cup as described above；The overflow cup
Nuclear power station is also respectively connected and operates normally I&C system and analyzer transmitter.
Slide bar as described above is vertically set on inside overflow cup, and slide bar upper end, magnetic float is arranged in the liquid-level switch contact
It is arranged on slide bar, magnetic float floats up and down under buoyancy along slide bar.
Liquid-level switch as described above is integrated in the overflow cup in sampling valve downstream, and liquid-level switch contact is in normally open,
It is connected on instrument signal output line, overflow cup is mounted on the position higher than measuring cup.
A kind of operation method of sodium table status monitoring device as described above, water sample enter gauge internal pipeline by sampling valve,
Alkalization bottle is flowed through after other valve, flowmeter adjust flow, measuring cup is entered after sample alkalization, and air pump is continuous into measuring cell
Bubble is blasted to believe the Na ion concentration chemistry in water sample to be measured with stirred sample and cleaning measuring electrode surface, electrode system
It is exported through transmitter to monitoring screen after number being converted to electric signal；
When overflow cup liquid level reach a certain height, liquid-level switch contact is closed under magnetic float magneticaction；When water processed
When system operates normally, overflow cup, which is in, is full of overflow situation, and magnetic float is close to liquid-level switch contact, and liquid-level switch contact is in magnetic
It is closed under float magneticaction, instrument signal normally exports to nuclear power station and operates normally I&C system, and master control room ASD is normally shown
Instrument currently measures indicating value；When water manufacturing system is stopped transport, sample introduction flow substantially reduces until stopping, at this time in overflow cup under liquid level
Drop, magnetic float drop down onto overflow bottom of the tube, and two contacts of liquid-level switch disconnect, and instrument stops output signal, master control room monitoring screen
Only exist channel failure warning note.
The invention has the following advantages:
When water manufacturing system is in stoppage in transit or inspecting state, liquid level decline in overflow cup, triggering liquid-level switch disconnects, stops
Upload communication, will not frequently occur sodium ion in master control ASD transfinites value alarm, and channel failure alarm, operator only occurs in instrument
State in conjunction with current system is the warning reason that can determine whether instrument, does not influence normal monitoring.Fortune and the instrument that comes into operation are moved back with manual
It compares, a large amount of manpower and material resources costs can be saved, while also having many advantages, such as that the response time is fast, resetting time is short.
