Description
Technical field
The utility model relates to a kind of device of monitoring generator unit stator water route hydrogen gas leakage, belongs to stator of steam turbine generator cooling water system technical field.
Background technology
On stator of steam turbine generator cooling water system water tank, conventional gas-monitoring instrument is the read out instrument of accumulation formula on the spot, although it can realize the object of flow measurement, but can not judge the gas componant and the purity that flow through gas-monitoring instrument, therefore, likely cause power plant's erroneous judgement.
Summary of the invention
The technical problems to be solved in the utility model is that the composition to gas, purity are analyzed judgement in the leakage gas flow of monitoring stator water route.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of device of monitoring stator water route hydrogen gas leakage, comprise stator cooling water tank interface, spilling water interface, condensate water discharge interface and row's air interface, stator cooling water tank interface connects the first stop valve, the first stop valve is connected with the second stop valve of parallel connection and one end of safety valve, it is characterized in that, the second stop valve in parallel and the other end of safety valve connect spilling water interface and purity sensor simultaneously, purity sensor serial connection flow sensor, flow sensor is connected with row's air interface and the 3rd stop valve simultaneously, the 3rd stop valve connects condensate water discharge interface.
The utility model has four large advantages:
1, can detect online hydrogen content in the flow of emission gases and gas.
2, be provided with safety valve and guarantee water tank pressure-fired, prevent that air from entering water tank and causing that mixing produces explosion hazard mixed gas with hydrogen.
3, can be on the spot and the long-range flow that simultaneously shows water tank emission gases, find that in time stator coil leaks hydrogen hidden danger, avoids fault spread.
4, be provided with pipeline condensate water floss hole, eliminate the possibility that condensate water inflow gas flowmeter exerts an influence to monitoring.
To sum up, the advantage that the utility model has concurrently rapidly, directly perceived, accurate, reliability is high, can be in the leakage gas flow of monitoring stator water route, composition to gas, purity are analyzed judgement, guiding operations staff carries out correct operation, can in the generator as heat eliminating medium, promote the use of to all use hydrogen.
Accompanying drawing explanation
The connection diagram of a kind of device of monitoring stator water route hydrogen gas leakage that Fig. 1 provides for the utility model;
The stereographic map of a kind of device of monitoring stator water route hydrogen gas leakage that Fig. 2 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 Figures 1 and 2, a kind of device of monitoring stator water route hydrogen gas leakage that the utility model provides, comprise stator cooling water tank interface a, spilling water interface b, condensate water discharge interface c and row's air interface d, stator cooling water tank interface a connects the first stop valve 2, the first stop valve 2 is connected with the second stop valve 5 of parallel connection and one end of safety valve 1, the second stop valve 5 in parallel and the other end of safety valve 1 connect spilling water interface b and purity sensor 3 simultaneously, purity sensor 3 is connected in series flow sensor 4, flow sensor 4 is connected with row air interface d and the 3rd stop valve 6 simultaneously, the 3rd stop valve 6 connects condensate water discharge interface c.
Once exceed the setting value of safety valve 1 from the gaseous tension of stator cooling water tank, safety valve 1 be will back down and purity sensor 3 and flow sensor 4 flow to, due to the pressure limiting effect of safety valve 1, the pressure in water tank is all the time in slight positive pressure state.Purity sensor 3 and flow sensor 4 simultaneously monitoring stream are crossed gas flow and the purity of intelligent gas meter, and can show on the spot gas flow and purity, remote signal output display gas flow.The gas that flows through purity sensor 3 and flow sensor 4 finally by exhaust main discharged to atmosphere.
Below intelligent gas meter, be provided with condensate water discharge interface c, in order to eliminate condensate water, flow into the possibility that intelligent gas meter exerts an influence to monitoring.
