Abstract
The invention discloses a kind of pipeline underground heat heat tracing still, including heat tracing still body and circulation pipe, it is characterized in that heat tracing still body is integral type or split type hermetic container, described heat tracing still body sets inlet tube and outlet, this internal vertical direction of described heat tracing still sets at least circulation pipe, and described circulation pipe is by support and heat tracing still body assembly connection.The material of described heat tracing still body is the metal that heat conductivility is excellent, and described circulation pipe is the straight tube of hollow, and height is 2/3～3/4 heat tracing still body height.Present configuration is scientific and reasonable, easy construction, and it is pretty good to invest little but heat tracing effect, is worthy to be popularized.
Description
Technical field
The present invention relates to gas transmission and distribution technical field, be specifically related to a kind of pipeline underground heat heat tracing still.
Background technology
Gas pressure regulating valve uses self-operated type structure mostly, and its operation principle is by acting on above core component epithelium
Spring force and the combustion gas lift of bottom, this disappears and other rises reaches autocontrol valve switch size, with the transmission & distribution that maintenance is more stable
Pressure.The normal working temperature of this epithelium is-10 DEG C～60 DEG C, and winter temperature is too low, or summer temperature is too high, all can be to epithelium
Duty affected.Temperature is the lowest, and epithelium can be by " numb with cold "；Temperature is the highest, also can make epithelium fatiguability thus cause
The situation that service life reduces.
The temperature the to be solved impact on pressure regulator valve duty, at present method predominantly recirculated water heat tracing and electricity add
Hot heat tracing two ways, the former has bidirectional temp regulation function, and the latter is suitable only for winter.The common defects that two ways exists is investment
Relatively costly, even there is certain potential safety hazard, as circulation needs source of recycled water and circulation power source, electric heating system
Then have the potential safety hazard that electric leakage brings.
Depth of soil is referred to as shallow top layer between 0～20cm, and its temperature is affected the biggest by outside climatic environment.There is money
Material shows, the month that China's soil moisture is minimum is January, is secondly 2, March and 11, December, and region is concentrated mainly on
Northeast and the Northwest.The monthly minimum of the soil moisture of the 20cm degree of depth is-12 DEG C, for Heilungkiang in January and Inner Mongol part
Area measured data, remaining month and area, the soil moisture is the most all more than-8 DEG C.Comparatively speaking, 20cm soil at a depth below
Earth temperature is affected by environment relatively small, is cool in summer and warm in winter for comparing ambient temperature, it is clear that utilize ground for gas pressure regulating valve
The optimal Cooling and Heat Source of hot heat tracing.
Summary of the invention
It is an object of the invention to provide a kind of not only economic, but also the pressure regulator valve heating device of safety and environmental protection, be specially one pipe
Road underground heat heat tracing still.
This practicality newly does to include heat tracing still body and circulation pipe, it is characterized in that heat tracing still body is integral type or split type close
Closing container, described heat tracing still body sets inlet tube and outlet, and this internal vertical direction of described heat tracing still sets at least circulation
Pipe, described circulation pipe is by support and heat tracing still body assembly connection.
The material of described heat tracing still body is the metal that heat conductivility is excellent, include but not limited to ferrum, copper, the one of aluminum or
Its alloy.
Described circulation pipe is the straight tube of hollow, and height is 2/3～3/4 heat tracing still body height.
In actual application, the present invention is arranged on upstream or the downstream pipe of voltage adjusting device, wherein heat tracing still Ontology
During 1/2 highly places into the soil, and heat tracing still body is simultaneously attached in the confined space of band insulation with voltage adjusting device.Work as pipeline
When inside having fuel gas flow, its heat of the combustion gas in the underground pipe network crossed by geothermal heating can heat companion when by heat tracing still body
This is the most external for hot still, air in couveuse；When in pipeline without fuel gas flow, due to the existence of underground heat, heat tracing still body is imbedded
There is the temperature difference in inside and outside (or deserving to be called down) of soil part, in heat tracing still body, combustion gas can circulate from bottom to top along circulation pipe, thus
BADIRE is conducted to outside heat tracing still, air in couveuse.Though two kinds of situations all can ensure voltage adjusting device in severe winter or heat,
All the time it is in comparatively ideal working environment.
The medicine have the advantages that scientific and reasonable for structure, easy construction, invests little but heat tracing effect pretty good, is worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
In figure, 1-heat tracing still body, 2-inlet tube, 3-outlet, 4-circulation pipe, 5-support, 6-combustion gas loop direction, 7-
Soil
Detailed description of the invention
In conjunction with Fig. 1, the present invention is described as follows:
A kind of pipeline underground heat heat tracing still, including heat tracing still body 1 and circulation pipe 4, is characterized in that heat tracing still body 1 is integrated
Formula or split type hermetic container, described heat tracing still body 1 sets inlet tube 2 and outlet 3, the most square in described heat tracing still body 1
To setting at least circulation pipe 4, described circulation pipe 4 is by support 5 and heat tracing still body 1 assembly connection.
The material of described heat tracing still body 1 is the metal that heat conductivility is excellent, includes but not limited to the one of ferrum, copper, aluminum
Or its alloy.
Described circulation pipe is the straight tube of 4 hollows, and height is 2/3～3/4 heat tracing still body 1 height.
In actual application, the present invention is arranged on upstream or the downstream pipe of voltage adjusting device, and wherein heat tracing still body 1 is about
1/2 highly places into the soil in 7, and heat tracing still body 1 is simultaneously attached to the close of band insulation with voltage adjusting device (not shown)
Close in space.When there being fuel gas flow in pipeline, the combustion gas in the underground pipe network crossed by geothermal heating, by heat tracing still body
The air within heat tracing still body 1 outside, couveuse can be heated when 1；When in pipeline without fuel gas flow, due to depositing of underground heat
, heat tracing still body 1 place into the soil 7 inside and outside (or deserving to be called down) part there is the temperature difference, combustion gas loop direction in heat tracing still body 1
4 as it is shown in figure 1, thus BADIRE is conducted to air in heat tracing still body 1 outside, couveuse.Two kinds of situations all can ensure pressure regulation
No matter equipment is in severe winter or heat, it is in all the time in comparatively ideal working environment.
Above example is only in order to illustrate technical scheme and unrestricted, and those skilled in the art are with reference to concrete real
Execute example technical scheme is modified, or other equivalent without deviating from technical solution of the present invention spirit and
Scope, it all should be contained in the middle of scope of the presently claimed invention.
