1、The first summarizeToday,internal sample of liquid dielectric in the oiltank is performed by ISO3170(GB/T4756-1998)Petrol liquid product handicraft sample law.It is impossibly to control accurately sample process. Usually the sample will not be exact.Performing personnels will feel tired as usual be
2、cause of hardwork.When rain or snow, climb oiltank that is a very dangerous job.When getting a sample at top of oiltank,easily volatile and noxious dielectric will injure someones，at one time，it will not be in favour of environment and the medium of oiltank will be polluted by other things from envi
3、ronment.For solving these problem, we have developed ” The auto control getting sample from oiltank” that according to ISO3170(GB/T4756-1998 criterion,it has achieved that liquid sample at different level of oiltank will be sampled. The machine operation is very simply、very accurate、excellently repe
4、ated,its structure is simple and it will be install very easily. It will not pollute the environment too. The sample machine has been awarded nationalpatent and the second prize of the sino petrol & chemical industry automation vocation 2010 year. The auto control getting sample from oiltank , its s

18、nk samplers characteristic and virtue1. Accurate sample locationThe sampler uses the patent technology” The liquid sample from oiltank Multilayer frame means expansion of type of zero gravity, the number of parent is ZL 200820029965.3”.We establish the database of multilayer frame means expansion ma
19、nufacture parameter by more and more test. We can assure that our multilayer frame means expansion can conquer connatural weak point that can not go up and down in ratio of equality by others. Assure every sample connection that been set in multilayer frame means expansion can automatically go up an
20、d down in ratio of equality with liquid level, to let it to truely get upper sample、middles ample、lower sample、upper middles lowes 1:1:1 uniform combination sample. If multilayer frame means expansion can go up and down in ratio of equality that will decide every connections definition of sample.For
21、 the drawing-1:the drawing-12. Independence of sample mediumThe sampler uses the patent technology” The sample devicment of Multi-dimensional sampling valve, the number of parent is ZL 200620079363.X” that is independent shunting plant of multilayer sample in the valve. It can take sample of every l
22、ocation independently shunt to lofting valve and can mix upper sample、middles ample、lower sample by the rate of 1:1:1 and take it to lofting valve, sample personnel can get every independent sample and 1:1:1 uniform combination sample from lofting valve exit.3、Security and reliability A) The self-tu
23、ning oil tank sampler uses the patent technology” The multichannel two globe valves, the number of parent is ZL 200720032338.0” that can fast cut off the communication of guitar pipe and pipe of outside, make sure that medium of oiltank will not leak out.The globe valvess button run reliably and acc
24、urately, its operation is simple and convenient B) The sampler only need be operated on the ground, and operationer need not climb to the top of oiltank to sample. Eliminate the danger of climbing in the rain or snow. Eliminate the danger when getting a sample at top of oiltank,easily volatile and n
25、oxious dielectric will injure someones. Take humanized and reliable environmental sample come true.4. Reasonable structure and simple operationThe sampler uses the patent technology” The sample devicment of Multi-dimensional sampling valve, the number of parent is ZL 200620079363.X ” that take multi
26、layer sample oil pipes scientifically and possibly combine into one of circular operation hand-actuated wheel. Operate the rated hand-actuated wheel to choice sample point. Take complex operation process to simple action.For drawing-2 Drawing-25. Hes-cling structure and little leaking pointScience a
27、nd reasonable The self-tuning oil tank sampler structure, Can the DuoGe sampling output line and a circulation return pipe road high oil chips in cluster. Make DuoGe independent sample line compact from a took over, the output to tank through within the operation of the DuoWei sampling valve ,This c
28、ompact structure tell the DuoGe lofting, thus greatly reducing valve sealing the number of points. In normal conditions using zero leakage .For drawing-3For drawing-36.Sample pipe road has reverse wash function: The self-tuning oil tank sampler take SKC-HF structure circulating pump But through the
29、cycle of the pump valve or reverse rotation oil change realize tank Sample pipe road, reverse through media Thus will CaiYangGuan way or tank sampling injector mesh on the plugging of dirt reverse wash to tanks, at any time to sampling the pipeline the cleaning 7. Replacement old way of the operatio
30、n is simple:The self-tuning oil tank sampler used specially developed for sampling convenient and special two tee lofting valve, Made with a conversion between lofting cycle is very simple, just press the valve for the arrows spin an Angle start after circulating pump can. 8. Convenient installation
31、: The sampler can be set up special steam heating device, oil tank external sampler components have straight heat conduction heat tracing of. For drawing-4 Use electric heating, in the valve body sampler exclusively electric tracing band through the heating channel, the heating effect ideal. A heati
32、ng device can be used for the sampler asphalt, and so easy as the medium tank. For drawing-49. Meet of the medium to sampling The sampler can be set up special steam heating device, oil tank external sampler omponents have straight heat conduction heat tracing of. Use electric heating, in the valve
33、body sampler exclusively electric tracing band through the heating channel, the heating effect ideal. A heating device can be used for the sampler asphalt, and so easy as the medium tank.The sixth The self-tuning the composition of the oil tank sampler The self-tuning oil tank sampler The compositio
34、n of the oil tank sampler as shown in figure 5 shows 1, extendable frame; 2, float group; 3, circulating pump 【 manual pump, pneumatic pump 】; 4, sampling combination tube; 5, sampling distribution device; 6, the integrated oil, a choice of the directional control valve, valve, sample combination di

36、tank with oil level within the truss and sample, the upper or lower, middle kind, samples and top samples (optional) sampling mouth all fixed in telescopic rack, telescopic frame in liquid is according to the proportion of sampling, ensure that came out of the position accuracy. The sampling locatio
37、n is determined according to the ISO3170 (GB/T4755 1998) oil liquid product manual sampling method regulation of sampling location of the design. For drawing-6 showsFor drawing-6Different sample position of the pipeline is independent sample through sampling combination tube transfer to oil chips, a
38、gain through the DuoWei reversing valve handwheel control of their respective independent leads to the valve, again by lofting lofting valve control lofting or cycle will turn to cycle the valve, start lofting circulation pump can turn number after the part of the old way of pipeline to the bottom o
39、f the tank replacement cycle; And then the valve position to rotate lofting lofting, can get the export of lofting valve in the tank is a position of the sample. Repeat the above。The upper, middle and lower sample sample: kind of combination is set in the sample by DuoWei reversing valves in a unifo
40、rm Distribution device to complete the combination. Through the handwheel rotation operation will turn to the combination mark can sample position: get the exact combination of samples. DuoWei globe valves are normally is often a state, it is used for emergency cut off in the tank pipe and outside storage tanks each sampling the sampler connection, and ensure that the oil in the tank is protected。The eighthSampler installation For drawing-7For drawing-7The ninth sampler operating methods
