Description
technical field
The present invention relates to pipeline pressure-measurement measurement mechanism technical field, be specifically related to a kind of anti-freeze type pressure pipe with heating tube.
Background technology
Pressure pipe is for measuring the open tube relative pressure of liquid, that be communicated in fluid to be measured.Can be used to monitor dam seepage line, osmotic pressure pressure, underground water table and around dam seepage flow etc.Be widely used in different fields, as industries such as oil, chemical industry, construction machinery production, colliery, shipbuilding, aviation, automobile, Industry Control, medicine equipments, to liquid in pipe, press force measurement application more extensive.Present applied pressure pipe, many employing electrical heating are wound around ribbon heater on pressure pipe, utilize electric energy to heat for pressure pipe, but there are some shortcomings in this pressure pipe, because device needs energising, so this pressure pipe is only applicable to apart from the nearer place of people's living environment, application conditions is restricted.Yet due to the setting position of pressure pipe generally all in the wild, switch on very difficult, and this heating means are very large to the consumption of electric energy, consumption of natural resource.Also some pressure pipe adopts hot water to follow (the 5th volume second phase 1986,4 of oilfield surface engineering [OSE]), but this pressure pipe is also because condition element is restricted.
Summary of the invention
The present invention proposes a kind of anti-freeze type pressure pipe with heating tube, and object is to solve existing pressure pipe the problem of frozen block easily occurs in the use procedure of severe cold area.
The present invention addresses the above problem the technical scheme of taking to be: a kind of anti-freeze type pressure pipe with heating tube of the present invention, comprise body, heating tube, thermal insulation separation thermosphere and fluid pipeline, body is provided with heating tube outward, heating tube is provided with insulation layer outward, body lower end vertically connects fluid pipeline, body upper end is connected with connecting pipe, by flange, connect, and be bolted, between body and connecting pipe, there is sealing gasket, on connecting pipe, connect a spherical valve, tensimeter is at the top of device, it is characterized in that: in heating tube, be provided with phase change medium, thermal insulation separation thermosphere peripheral hardware has locating ring.
In described heating tube, phase change medium is alcohol.
Described thermal insulation separation thermosphere adopts the phenol formaldehyde foam that thickness is 4cm.
Described heating tube pipe wall material adopts stainless steel, and thickness is 1mm.
Temperature in the measured fluid pipeline of this pressure pipe must be higher than the boiling point of alcohol, and temperature range is between 80-200 degrees Celsius.
Described thermal insulation separation thermosphere has uniform hole-closing structure.
The invention has the beneficial effects as follows: do not need external energy, overcome the energising difficult problem of traditional pressure pipe, both played the heating effect of pressure pipe, effectively prevented the generation of the frozen block phenomenon of pressure pipe; Saved again the energy; Pressure pipe facilitates, accurately locates in device; Thermal insulation separation thermosphere has uniform hole-closing structure, and coefficient of heat conductivity is low, and heat-insulating property is good; The present invention is simple in structure, with low cost, safety and environmental protection, and long service life, is a kind of device being worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is main sectional structure schematic diagram of the present invention.
Embodiment
In conjunction with Fig. 1, present embodiment is described, a kind of anti-freeze type pressure pipe with heating tube, comprise body 7, heating tube 8, thermal insulation separation thermosphere 6 and fluid pipeline, the outer heating tube 8 that is provided with of body 7, the outer insulation layer 6 that is provided with of heating tube 8, body 7 lower ends vertically connect fluid pipeline, body 7 upper ends are connected with connecting pipe 3, by flange 11, connect, and fixed by bolt 10, between body 7 and connecting pipe 3, there is sealing gasket 4, on connecting pipe 3, connect a spherical valve 2, tensimeter 1 is at the top of device, in heating tube 8, be provided with phase change medium 5, the outer locating ring 9 that is provided with of thermal insulation separation thermosphere 6.The interior phase change medium 5 of described heating tube 8 is alcohol.So arrange, alcohol is to responsive to temperature, and liquid phase changes fast, and heat release is rapid, and heating effect is good.Described thermal insulation separation thermosphere 6 adopts the phenol formaldehyde foam that thickness is 4cm.Described heating tube 8 pipe wall materials adopt stainless steel, and thickness is 1mm.So arrange, the heat-transfer effect of steel pipe is good, and the high insulating effect of phenol formaldehyde foam effectively prevents scattering and disappearing of heat.Temperature in the measured fluid pipeline of this pressure pipe must be higher than the boiling point of alcohol, and temperature range is between 80-200 degrees Celsius.So arrange, be heated effective, pressure pipe is accurate to its measurement.Described thermal insulation separation thermosphere 6 has uniform hole-closing structure.Coefficient of heat conductivity is low, and heat-insulating property is good.
Body 7 need to have certain intensity and sealing, and needs good heat conductivility, therefore adopts weldless steel tube, and body 7 of the present invention adopts the 1Cr18Ni9Ti stainless-steel tube of φ 12 * 1, and wall thickness is 0.8mm.Heating tube 8 adopts the also 1Cr18Ni9Ti stainless-steel tube of φ 12 * 1, and thickness is 1mm, outside it, phase change medium 5 alcohol is housed in heating tube 8 with body 7 concentric locking collars.Thermal insulation separation thermosphere 6 adopts phenol formaldehyde foam, and thickness is 4cm, is tightly wrapped in outside heating tube 8.The pressure tappings of body 7 adopts ligulate pressure tappings, and pressure tappings is back to liquid flow direction, in order to avoid change dynamic pressure into static pressure.Body 7 is connected with connecting pipe 3 by flange, adds the tooth profile metal sealing gasket 4 that one deck 2mm is thick between body 7 and connecting pipe 3, prevents leak of liquid.Between connecting pipe 3 and tensimeter 1, be provided with spherical valve 2, contribute to overhaul of the equipments.
The present invention is in the situation that weather is colder, the outer wall of the thermal insulation separation thermosphere 6 outside locating ring 9 and heating tube 8 is close to, length the location of according to the scale of mark on body 7, adjusting insertion, body 7 vertically interts in the pressure tap of fluid pipeline, adopts welding process with the connected mode of fluid pipeline.Because working fluid temperature in pipe is higher, therefore after heating tube 8 bottoms become alcohol gas near the alcohol endothermic gasification of fluid pipeline, alcohol gas rises to heating tube 8 tops, thereby and the liquid in heat release heating tube 8 bodies 7, alcohol gas after heat release liquefies again, and the gas again being distilled replaces.This process is continuous, thereby is continuously pressure pipe heating.
