Description
[technical field]
The utility model relates to gas supply auxiliary facility technical field, specifically a kind of segmentation control heating blanket of gas supply system.
[background technology]
Be stored in gas (NH3, BCL3 etc.) in steel cylinder when it is in use because meeting produces the liquid transformation to gaseous state in liquid mode, whole steel cylinder can output heat absorption phenomenon, and temperature can reduce along with the increase of gas consumption.At this moment need on steel cylinder, install heating blanket heating steel cylinder additional, give temperature-compensating of steel cylinder, and by temperature control equipment control constant output temperature.Traditional heating blanket is inserted heater strip in silicon rubber, and a temperature inductor is installed, then by outside temperature control box control.Temperature control box is controlled the work of heater strip or stops by obtaining the temperature feedback of heating blanket.But traditional heating blanket runs into such problem in use: in the time of the gas of full bottle, heating blanket can well be controlled whole steel cylinder temperature.Once but a liquid level reduces in bottle, does not have the local temperature of liquid level to tend to higher than the temperature that has liquid level in heating blanket, and be reduced to temperature inductor once when position when liquid level, the temperature that will cause actual feedback is not the actual temperature that is heated liquid.Finally cause evaporation capacity inadequate.In addition without any safety precautions, there is serious potential safety hazard in this heating blanket, in use procedure.
[utility model content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and segmentation control heating blanket that a kind of gas supply system is provided, can control uniformly whole steel cylinder temperature, after avoiding liquid level to decline, local temperature is too high, liquid level heats inadequate phenomenon in the time of low temperature, and use is very safe, reliable, also plays energy-conservation effect.
Design for achieving the above object a kind of segmentation control heating blanket of gas supply system, comprise heating blanket body 11, temperature control box 12, the two ends of described heating blanket body 11 are provided with fixing hole 13, in described fixing hole 13, fixed part 5 is housed, described heating blanket body 11 is by multiple independent heating cell formations, described each independent heating unit comprises thermal insulation layer 31, heater strip 32 and insulating outer layer 33, described thermal insulation layer 31 is provided with temperature inductor 9, temperature switch 10, and described heater strip 32, temperature inductor 9, temperature switch 10 are by connection temperature control box 12.
Between described heater strip 32 and insulating outer layer 33, be provided with screen 1, heat-insulation layer 34, between described heater strip 32 and thermal insulation layer 31, be provided with screen 2 36, described screen 1, screen 2 36 are by connection temperature control box 12.
Described heating blanket body 11 is made up of independent heating unit 1, independent heating unit 2 22, independent heating unit 3 23.
Described fixed part 5 adopts elastic tightening band.
The utility model compared with the existing technology, novel structure, simple, by by heating blanket by being divided into multiple independently temperature controls region under upper, and monitor in real time the temperature at each section of position of steel cylinder by the temperature inductor in each region, after liquid level declines, epimere or stage casing output reduce the temperature equalization of the whole steel cylinder of guarantee.After avoiding liquid level to decline, local temperature is too high, and liquid level heats inadequate phenomenon in the time of low temperature.Localized heating can also reduce the output of heating blanket entirety in the time of low liquid level, plays energy-conservation effect; In addition, the utility model is also provided with excess Temperature and earth leakage protective measure, uses very safely, and automaticity is high, is worthy of popularization.
