Description
Technical field
The utility model relates to the device of arranging safely hydrogen in a kind of generator hydrogen gas system under the state of emergency, belongs to steam turbine generator hydrogen gas system technical field.
Background technique
Because the heat exchange efficiency of hydrogen is high, loss is little, so large turbo-type generator usually adopts hydrogen_cooling, this is very practical method.But hydrogen mixes the accident of may blasting with air, the percentage composition of hydrogen in mixed gas is lower than 4% or be safe mixed gas higher than 74% time side, therefore when using the steam turbine generator of hydrogen_cooling, Security must effectively be guaranteed.
At conventional thermal power plant, the most frequently used urgent row's hydrogen mode is manually to arrange hydrogen, and the danger of personnel's operation is very large.Nuclear power generator has used urgent row's hydrogen design proposal that solenoid valve automatic remote is controlled, but still have potential safety hazard, because break down and cannot open once this solenoid valve, just can not reach object urgent, quick, safety dumping hydrogen, finally may cause generator not arrange in time hydrogen and explosion caused incidents.
Summary of the invention
The technical problems to be solved in the utility model is to provide device a kind of high security, that can automatic remote control the hydrogen in emptying generator.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide the device of safety row hydrogen under a kind of state of emergency, it is characterized in that, comprise the shunt circuit being formed in parallel by least two way solenoid valve series loops, one end access emptying pipe of this shunt circuit, the other end is connected to hydrogen control unit, and every way solenoid valve series loop comprises the solenoid valve of at least two series connection, and each solenoid valve is energising and cuts out and power-off is opened.
Preferably, also comprise Pressure testing spare interface, the corresponding Pressure testing spare interface of every way solenoid valve series loop, i Pressure testing spare interface accesses between the solenoid valve of adjacent two series connection in the series loop of i way solenoid valve via pipeline.
Preferably, described in each solenoid valve all connect one be positioned at far-end for showing the display unit of current solenoid valve state.
Preferably, described in each, the outside of solenoid valve is all connected in series a stop valve.
The utility model utilization principle in parallel and series connection while redundancy protecting increases the safety reliability of device row hydrogen, and in the middle of every pair of solenoid valve, detection interface is set, and can by online Pressure testing, reflect whether solenoid valve has damaged condition at any time.
The utility model has four large advantages:
1, many solenoid valves redundancy protecting, Security is high;
2, in the middle of every pair of solenoid valve, Pressure testing interface is set, once pressure raises, just can detects online the sealability of any one solenoid valve, process in time;
3, every pair of solenoid valve two ends arrange stop valve, make any one solenoid valve can under non-stop-machine state, isolate replacing;
4, the unlatching of solenoid valve or close by "on" position determines, Full-automatic remote is controlled, and guarantees operator safety.
In sum, the utility model has stable, efficient, practical, safe and reliable advantage concurrently, in all generators using hydrogen as cooling medium, can promote the use of, can avoid under emergency, high-rating generator cannot be arranged hydrogen and the incidents that sets off an explosion safely.
Accompanying drawing explanation
The connection diagram of the device of safety row hydrogen under a kind of state of emergency that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, the utility model is described further.
As shown in Figure 1, the device of safety row hydrogen under a kind of state of emergency that the utility model provides, comprise the shunt circuit being formed in parallel by two way solenoid valve series loops, one end access emptying pipe of this shunt circuit, the other end is connected to hydrogen control unit, every way solenoid valve series loop comprises the solenoid valve of two series connection, be the solenoid valve 2 in Fig. 1, solenoid valve 3, solenoid valve 4 and solenoid valve 5, in the outside of each solenoid valve, be all in series with a stop valve, make the two ends of each solenoid valve can have a stop valve, each solenoid valve is energising and cuts out and power-off is opened.The corresponding Pressure testing spare interface of every way solenoid valve series loop, i Pressure testing spare interface accesses between the solenoid valve of adjacent two series connection in the series loop of i way solenoid valve via pipeline.Described in each solenoid valve all connect one be positioned at far-end for showing the display unit 1 of current solenoid valve state.
When steam turbine generator normally moves, solenoid valve 2, solenoid valve 3, solenoid valve 4 and solenoid valve 5 are energising closed condition, hydrogen is sealed in generator, now, no matter any one solenoid valve is opened because of fault, has another solenoid valve of series connection with it to guarantee there will not be the phenomenon of hydrogen gas leakage; When steam turbine generator occurs that emergency need to be arranged hydrogen, no matter any one solenoid valve cannot be opened because of fault, has a way solenoid valve in parallel with it to guarantee generator automatic hydrogen-discharging smoothly, without manual operation.
In addition, under non-stop-machine state, by the detection interface arranging in the middle of every way solenoid valve is carried out to Pressure testing, the pressure value obtaining can carry out clear and definite judgement to the sealing of any one solenoid valve.And be provided with stop valve at every pair of solenoid valve two ends, make any one fault solenoid valve under non-stop-machine state, to isolate replacing.
The unlatching of solenoid valve or close by "on" position determines, can control by Full-automatic remote, thoroughly guarantees operator safety.
