Description
Technical field
This utility model one Air-Cooling Island freezing prevention tubing structure, belongs to Air-Cooling Island freezing prevention tubing technical field.
Background technology
Existing Air-Cooling Island main pipeline butterfly valve easily freezes when closing in the winter time bursting by freezing, owing to air cooling butterfly valve is expensive,
Cause operating cost to increase, and additionally main pipeline butterfly valve the most easily receives the erosion of dust storm, causes damaging.
Utility model content
This utility model overcomes the deficiency that prior art exists, it is provided that a kind of Air-Cooling Island freezing prevention tubing structure, not only
Can ensure that butterfly valve, not by bursting by freezing, extends the service life of butterfly valve, and can also play the effect of checking the wind and fixing the shifting sand.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of Air-Cooling Island freezing prevention tubing knot
Structure, including Air-Cooling Island body, supervisor and butterfly valve, described supervisor is connected on Air-Cooling Island body, and described butterfly valve is arranged on supervisor,
Being provided with frost box on described supervisor, butterfly valve is covered by described frost box, and described frost box is used for protecting butterfly valve in order to avoid bursting by freezing.
Being provided with accompanying-heat cable in described frost box, described accompanying-heat cable is wound around and is arranged on butterfly valve, carries out auxiliary to butterfly valve
Help heating, it is ensured that butterfly valve is not by bursting by freezing.
Being provided with temperature sensor on described butterfly valve, described temperature sensor is by wire and Power Plant DCS control system electricity
Connecting, described accompanying-heat cable also electrically connects with Power Plant DCS control system, and described Power Plant DCS control system will by temperature sensor
After the temperature signal analytical calculation that temperature sensor gathers, when the temperature of butterfly valve is less than design temperature, control accompanying-heat cable pair
Butterfly valve heats.
Described butterfly valve is motor-operated isolation valve.
This utility model compared with prior art has the beneficial effect that this utility model is at Air-Cooling Island main pipeline butterfly valve
Place adds frost box, arranges accompanying-heat cable, temperature sensor, be connected with Power Plant DCS control system in frost box, and accompanying-heat cable is less than
Automatically heat during technological temperature, can be to air cooling main pipeline and butterfly valve anti-frost protection.Air cooling butterfly valve is expensive and winter closes
Shi Rongyi icing bursting by freezing, arranges automatic heating device and can well protect the good of air cooling motor-operated isolation valve and whole air cooling system
Good operation, improves temperature mode and the reliability of whole air cooling system.The most applicable in severe cold area.Wind-proof can be played simultaneously
Husky effect.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further.
Fig. 1 is structural representation of the present utility model.
In figure: 1 be Air-Cooling Island body, 2 be supervisor, 3 be butterfly valve, 4 be frost box, 5 be accompanying-heat cable, 6 for temperature sensing
Device, 7 it is Power Plant DCS control system.
Detailed description of the invention
As it is shown in figure 1, this utility model one Air-Cooling Island freezing prevention tubing structure, including Air-Cooling Island body 1, supervisor 2 and butterfly
Valve 3, described supervisor 2 is connected on Air-Cooling Island body 1, and described butterfly valve 3 is arranged on supervisor 2, described supervisor 2 is provided with antifreeze
Case 4, butterfly valve 3 is covered by described frost box 4, and described frost box 4 is used for protecting butterfly valve 3 in order to avoid bursting by freezing.
Being provided with accompanying-heat cable 5 in described frost box 4, described accompanying-heat cable 5 is wound around and is arranged on butterfly valve 3, enters butterfly valve 3
Row auxiliary heating, it is ensured that butterfly valve 3 is not by bursting by freezing.
Being provided with temperature sensor 6 on described butterfly valve 3, described temperature sensor 6 is by wire and Power Plant DCS control system
7 electrical connections, described accompanying-heat cable 5 also electrically connects with Power Plant DCS control system 7, and temperature is passed by described Power Plant DCS control system 7
After the temperature signal analytical calculation that temperature sensor 6 is gathered by sensor 6, when the temperature of butterfly valve 3 is less than design temperature, control companion
Butterfly valve 3 is heated by electric heating cable 5.
Described butterfly valve 3 is motor-operated isolation valve.
This utility model adds frost box at Air-Cooling Island main pipeline butterfly valve (i.e. motor-operated isolation valve) place, arranges heat tracing in frost box
