Description
Technical field
The present invention relates to high-temperature gas leak detection technology field, is used for nuclear power station more specifically to one kind and positions
The detection system of leakage.
Background technology
In the prior art, mainly there are three kinds to the method for high-temperature gas leakage, overheat monitoring, one of which is point type temperature
Sensor, i.e., by the temperature sensor in fragile and leakage position arrangement measurement point type, by sensing surrounding catheter air
The change of temperature come determine whether gas leakage or pipe overheat.Because general high temperature conduit piping arrangement is longer, and exist
Compared with connectors and movable part, this kind of detection method needs to arrange a large amount of temperature sensors, and circuit is very numerous and diverse；Meanwhile by
It is only capable of detecting on preset position in the temperature sensor of point type, substantial amounts of measurement blind area is present.
Another is line detector, and line detector main at present mainly has irrecoverable and can recover two kinds：
Whether beyond retrievable provides on-off model, the change that renewable type passes through the resistance value between cable by the conducting of cable
Provide analog signalses.Alarm signal is provided and can not realize that it is let out when overheat however, both detectors can only be realized
Reveal the positioning of position.
The third is tonometry, sets pressure sensor by the diverse location in high-temperature gas conduit, passes through survey
Amount conduit in pressure change determine whether to leak, the measuring method can be used for gross leak measurement, for Small leak due to
The change of environmental control system operating mode, catheter interior pressure have certain fluctuation, plus the pneumatic hysteresis quality of pressure measxurement, it is difficult to sentence
It is disconnected whether to have leakage.Although Small leak is for the performance impact very little of environmental control system, because gas temperature is very high, conduit is small to be let out
The harm for bringing perimeter systems is leaked then to can not be ignored.In addition, although upstream leakage can be carried out by the pressure change in downstream
Judge, but it can not be accurately positioned the particular location of leakage, while the shortcomings of quality weight also be present in the measuring method.
How to provide it is a kind of it is simple in construction, reliability is high, applied widely and with being used for nuclear power station positioning leak
The high-temperature gas leak detection system of capability, turn into those skilled in the art's important technological problems to be solved.
