Description
Technical field
The utility model relates to a kind of corrosion and control device of material microscopic examination, and it is particularly useful for the automatic temperature-control Huey test device regularly of stainless steel material.
Background technology
Along with the more and more harshness of oil and gas development, processing industry corrosion environment, the carbon steel and low alloy steel material of corrosion stability difference has been difficult to satisfy the needs of production and processing.Because it is low, in light weight that stainless steel pipe has maintenance cost, and the characteristics of longer service life, become the focus of oil and gas industry selection, have huge economic benefit.Yet stainless steel pipe causes the material sensitization if thermal treatment is improper or welding process is improper, is easy to produce intercrystalline corrosion.Produce the stainless steel pipe of intercrystalline corrosion, when receiving stress, promptly can intercrystalline fracture, intensity almost completely disappears, because intercrystalline corrosion is difficult for inspection, so the unexpected destruction of causing equipment is very harmful.So must check its intercrystalline corrosion performance during to the stainless steel pipe quality assessment.
At present, China's test standard commonly used is GB/T 4334-2008 " the corrosion stainless steel intercrystalline corrosion test method of metal and alloy ".When making an experiment by standard code, the material sample that needs a person with the qualifications of a general is put into the etchant solution Continuous Heat corrosion 2,16,48,120 hours of boiling, could accomplish Huey test.Existing corrosion testing apparatus is made up of electric heater, the reflux condenser that the conical flask of corrosive liquid is housed and is installed in flask upper end, and the liquid coolant of reflux condenser is provided by tap water.There is following problem in use in this device: 1) must have manual work day and night on duty so that cut off the water supply or accomplish heat time heating time after in time cut off the electricity supply; 2) conical flask is young, and very inconvenient when dress is materialsed, sample size is restricted simultaneously, is unfavorable for the sample survey when workload is big; Standard-required solution keeps little boiling when 3) selecting sulfuric acid-copper sulphate corrosion test for use, and conventional electric heater adds thermally labile, is prone to cause experimental data inaccurate.Chinese patent CN 201653870U discloses a kind of intercrystalline corrosion automatic gauging appearance, and this apparatus structure is simple, and safety and stability has improved automaticity.The inconvenience but this device dress is materialsed has adopted traditional electrical to heat simultaneously and has caused the solution concentration instability and finally cause check data inaccurate.
Therefore, existing test unit working costs effort can't be accomplished Huey test efficiently, safely, accurately.
The utility model content
The utility model purpose provides a kind of automatic temperature-control Huey test device regularly.But this device automatic temperature-control swift to operate, accomplish Huey test regularly, safely, exactly.
The described a kind of automatic temperature-control of the utility model Huey test device regularly is made up of reflux condensing tube, flow sensor, temperature sensor, section beaker, plane cover plate, electric jacket and control circuit; The section beaker places electric jacket, and the plane cover plate places on the section beaker, and the ring groove of plane cover plate and section beaker surface of contact is embedded with O-ring seal; Temperature sensor passes the plane cover plate and inserts in the section beaker, keeps in touch with corrosive liquid in the beaker; Reflux condensing tube is fixed on the rubber plug ring in the cover central hole of plane, and with the section beaker in be communicated with, reflux condensing tube and condensate pipe join, flow sensor is installed on the condensate pipe; Flow sensor, temperature sensor and electric jacket are connected with control circuit;
Flow sensor switch and timer that control circuit joins by the power switch that is connected with AC power, with flow sensor are formed; Power switch, flow sensor switch and timer three connect and link to each other with relay; Relay links to each other with temperature controller, transformer; Temperature controller links to each other with temperature sensor, and the other end and the electric jacket of transformer join, and are connected with AC power.
The course of work of the utility model is: at first closed power switch, open water valve, and import heat time heating time at timer, in temperature controller input heating-up temperature, at this moment, with flow sensor switch and timer contact closure, relay conducting.Temperature controller is regulated the heating voltage of electric jacket through transformer.When temperature sensor detected the etchant solution heating-up temperature and reaches input temp, the temperature controller control transformer made its sustaining voltage constant, thereby made the electric jacket heating constant, and this moment, etchant solution stably kept slight boiling condition.If solution does not reach boiling or violent boiling, can regulate through the input temp of temperature controller.Sense condensate water cutout or flow when too small when flow sensor, the automatic cutout of flow sensor switch contact is cut off the electricity supply, and stops heating.This moment, timer also quit work, and showed excess time.But Closing Switch continues work excess time when condensation flow is recovered; Perhaps working as the timer time counting was zero (representing that promptly the hot corrosion time arrives), and the timer contact breaks off cuts off the electricity supply off-test.When adorning appearance with sampling, the plane cover plate is together taken off together with the reflux condensing tube and the temperature sensor that are fixed on above it, can be through convenient dress appearance of the section beaker of spaciousness and sampling.
The beneficial effect of the utility model is: 1) when condensate water cutout or flow are too small, but automatic cutout cut off the electricity supply, prevent dangerous situation.When current recover to continue work excess time.Or when test period finished, this device also can be cut off the electricity supply automatically and stopped heating.Improve the automaticity of Huey test device, realized the Huey test Automatic Control; 2) adopted the section beaker of wide-mouth, not only fast easy to operate during with sampling dress appearance, and increased container volume, and increased sample-loading amount, improved work efficiency; 3) electric jacket that has adopted controllable temperature can be stablized heated solution and make it keep slight boiling condition as heating tool, has improved the test degree of accuracy; 4) simple in structure, simple operation, low cost of manufacture.
