Description
Technical field
A kind of instrument and the technical field of measurement are the utility model is related to, relates more specifically to a kind of instrument tracing system.
Background technology
Various regions temperature in winter and extreme minimum temperature are widely different.Certain areas are seen by temperature on average, can be not required to
Want heat tracing.But perhaps extreme minimum temperature can influence the instrument of outdoor installation and the normal work of measuring system, so should be according to
These regional environment extreme minimum temperatures determine the heat tracing of instrument and measuring system.
Because the medium species of chemical engineering measurement object is various, the physical characteristic such as its condensation temperature is also different, so instrument
Table and measuring system may have phenomena such as freezing, condense, crystallizing, separating out at ambient temperature.Material measures pipeline and detector
Table perhaps can not meet minimum environment temperature requirement, thus instrument must use tracing system.
Instrument tracing system type has low-pressure steam heat tracing (tracing steam 0.46MPa, 150 DEG C), hotwater tracing at present
(side het water 0.9MPa, 90 DEG C) and electric tracing, wherein temperature of the steam tracing pipeline in incubator are least easily controlled.Firm
When entering winter or temperature and getting warm again after a cold spell, it is bad and cause to be incubated the too high feelings of the temperature inside the box easily to occur heat tracing temperature control in insulation box for instrument
Condition, temperature when serious in incubator can reach 70 to 80 DEG C, and the operating temperature of general instrument is between 0 to 60 DEG C.If
Instrument is chronically under hot environment and worked, and can cause gauge internal electronic component accelerated ageing, in some instances it may even be possible to occur what is damaged
Situation.This may influence the normal production of device, and serious even causes device disastershutdown.
In general low-pressure steam tracing system, instrument and pressure guiding pipe carry out heat tracing in the corresponding incubator of a pipeline.
In real work, instrument attendant can only carry out hand switch valve operation by steam tracing distribution station at the scene.General point
Gate valve is used with station, the type valve is opened smaller little with larger difference.Therefore the temperature in insulation box for instrument is led to
It is often all very high, the purpose for controlling heat tracing temperature within the specific limits is unable to reach, this causes heat tracing temperature overtemperature in incubator
Situation happens occasionally.
Utility model content
Main purpose of the present utility model is to transform the heat traced pipeline inside existing insulation box for instrument, both reaches
The temperature of incubator is controlled within the specific limits, prevents overtemperature, ensures instrumentation energy long-period stable operation again.
To achieve these goals, the utility model provides a kind of instrument tracing system, including incubator, the incubator
Closing space is limited to accommodate instrument, wherein, the first heat tracing loop and the second heat tracing loop are additionally provided with the incubator, and
And the first heat tracing loop and the second heat tracing loop can independently be the incubator and provide heat.
Further, the first heat tracing loop is that the heat in the unit interval that the incubator provides is less than second companion
Hot loop is the heat in the unit interval that the incubator provides.
Further, the first heat tracing loop and the second heat tracing loop are steam companions, and described
The both ends in the both ends in one heat tracing loop and the second heat tracing loop are respectively connecting to steam tracing inlet tube and steam tracing goes out
Mouth pipe.
Further, the both ends in the both ends in the first heat tracing loop and the second heat tracing loop connect by three respectively
Head is connected to steam tracing inlet tube and steam tracing outlet.
Further, the first valve for controlling the first heat tracing loop is provided with the first heat tracing loop；Institute
State the second valve being provided with the second heat tracing loop for controlling the second heat tracing loop.
Further, first valve is connected to the first heat tracing loop by socket weld, and second valve passes through
Socket weld is connected to the second heat tracing loop.
Further, the first heat tracing loop is less than the second heat tracing loop in the distance of the incubator inside turn
In the distance of the incubator inside turn.
Further, kept between the first heat tracing loop and the second heat tracing loop and the inwall of the incubator
Spacing distance.
Further, the first heat tracing loop, the second heat tracing loop, the steam tracing inlet tube and steam companion
Hot outlet is seamless steel pipe.
Further, the second heat tracing loop includes vertical heat tracing pipeline section and horizontal heat tracing pipeline section, and the instrument is set
Position between the first heat tracing loop and the horizontal heat tracing pipeline section.
The beneficial effects of the utility model are that, when just entering the winter or temperature gets warm again after a cold spell, instrument tracing system only needs to put into operation
Less first heat tracing loop.Open the first valve, close the second valve, due to the first heat tracing loop incubator inside turn away from
From shorter, relatively good control temperature, this ensures that environment temperature not superhigh temperature or ultralow temperature in incubator；Into the severe winter
Afterwards, tracing system needs big loop of putting into operation, and at this moment opens the second valve, closes the first valve, the second heat tracing loop is entirely being incubated
Case inside turn one is enclosed, heat tracing pipe line length, and is not close to insulation tank wall, reduce radiated energy, so by adjust the first valve and
Switching to adjust the environment temperature in incubator for second valve, ensures the environment temperature in incubator between 0-50 DEG C, so as to
Ensure instrumentation long-period stable operation.
It should be understood that in the environment of extreme low temperature, the first valve and the second valve can also be opened simultaneously so that first
Heat tracing loop works simultaneously with the second heat tracing loop, there is provided more preferable heat tracing effect.
