Description

With the anti-freeze type pressure pipe of heating tube
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 for measure the relative pressure of liquid, the open tube that is communicated in fluid to be measured.Can be used to monitoring 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, extensive to the measurement Application comparison of liquid in pipe pressure.The pressure pipe applied now, namely many employings electrical heating is wound around ribbon heater on pressure pipe, electric energy is utilized 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.But due to the setting position of pressure pipe general all in the wild, be energized very difficult, and this heating means are to the consumption of electric energy very greatly, consumption of natural resource.Also some pressure pipe adopts hot water with (oilfield surface engineering [OSE] the 5th volume second phase 1986,4), 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 solves the problem that frozen block easily occurs existing pressure pipe in the use procedure of severe cold area.
The present invention is the technical scheme taked that solves the problem: a kind of anti-freeze type pressure pipe with heating tube of the present invention, comprise body, heating tube, heat insulation layer and fluid pipeline, heating tube is provided with outside body, heat insulation layer is provided with outside heating tube, body lower end vertically connects fluid pipeline, body upper end is connected with connecting pipe, pass through Flange joint, and be bolted, sealing gasket is had between body and connecting pipe, connecting pipe connects a spherical valve, tensimeter is at the top of device, it is characterized in that: in heating tube, be provided with phase change medium, locating ring is provided with outside heat insulation layer.
In described heating tube, phase change medium is alcohol.
Described heat insulation layer adopts thickness to be the phenol formaldehyde foam of 4cm.
Described heating tube pipe wall material adopts stainless steel, and thickness is 1mm.
Temperature in fluid pipeline measured by this pressure pipe must higher than the boiling point of alcohol, and temperature range is between 80-200 degrees Celsius.
Described heat insulation layer 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 served the heating effect of pressure pipe, effectively prevent the generation of the frozen block phenomenon of pressure pipe; In turn save the energy; Pressure pipe facilitates, accurately locates in device; Heat insulation layer has uniform hole-closing structure, and coefficient of heat conductivity is low, and heat-insulating property is good; Structure of the present invention is simple, and with low cost, safety and environmental protection, long service life is a kind of device be worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is main sectional structure schematic diagram of the present invention.
Embodiment
Composition graphs 1 illustrates present embodiment, a kind of anti-freeze type pressure pipe with heating tube, comprise body 7, heating tube 8, heat insulation layer 6 and fluid pipeline, heating tube 8 is provided with outside body 7, heat insulation layer 6 is provided with outside heating tube 8, body 7 lower end vertically connects fluid pipeline, body 7 upper end is connected with connecting pipe 3, connected by flange 11, and fixed by bolt 10, sealing gasket 4 is had between body 7 and connecting pipe 3, connecting pipe 3 connects a spherical valve 2, tensimeter 1 is at the top of device, phase change medium 5 is provided with in heating tube 8, locating ring 9 is provided with outside heat insulation layer 6.In described heating tube 8, phase change medium 5 is alcohol.Setting like this, alcohol is to responsive to temperature, and liquid phase changes fast, and heat release is rapid, and heating effect is good.Described heat insulation layer 6 adopts thickness to be the phenol formaldehyde foam of 4cm.Described heating tube 8 pipe wall material adopts stainless steel, and thickness is 1mm.Setting like this, the heat-transfer effect of steel pipe is good, the high insulating effect of phenol formaldehyde foam, effectively prevents scattering and disappearing of heat.Temperature in fluid pipeline measured by this pressure pipe must higher than the boiling point of alcohol, and temperature range is between 80-200 degrees Celsius.Setting like this, is heated effective, and the measurement of pressure pipe to it is accurate.Described heat insulation layer 6 has uniform hole-closing structure.Coefficient of heat conductivity is low, and heat-insulating property is good.
Body 7 needs 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 1Cr18Ni9Ti stainless-steel tube of also φ 12 × 1, and thickness is 1mm, and with body 7 concentric locking collar outside it, heating tube 8 is built with phase change medium 5 alcohol.Heat insulation layer 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, pressure tappings 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, prevent leak of liquid between body 7 and connecting pipe 3.Be provided with spherical valve 2 between connecting pipe 3 and tensimeter 1, contribute to overhaul of the equipments.
The present invention is when weather is colder, locating ring 9 is close to the outer wall of the heat insulation layer 6 outside heating tube 8, adjust the length of insertion according to the scale of mark on body 7 and locate, body 7 vertically interts in the pressure tap of fluid pipeline, adopts welding process with the connected mode of fluid pipeline.Because Bottomhole pressure fluid temperature is higher, therefore heating tube 8 bottom alcohol gas after the alcohol endothermic gasification of fluid pipeline becomes alcohol gas rises to heating tube 8 top, and heat release thus liquid in heating tube 8 body 7, alcohol gas after heat release liquefies again, is replaced by the gas again distilled.This process is continuous, thus is continuously pressure pipe heating.
