Abstract
The utility model relates to the anti-retention structure of sampling line in a kind of LNG on-line period system, comprises sampling line, electric heating gasification device, first flow variable valve, and described electric heating gasification device and first flow variable valve are arranged on sampling line successively.The utility model, owing to increasing electrical heating pressurizing valve, variable valve in sampling line, for realizing the flow controlling sampling line LNG in pipeline, prevents the system that LNG is detained in pipeline.
Description
Technical field
The utility model relates to the anti-retention structure of sampling line in a kind of LNG on-line period system, belongs to LNG on-line period system accessory field.
Background technology
Because LNG sampling system stop valve is excessive, the problems such as the vaporization rate deficiency of low power gasifier and sampling line connection, after causing LNG to enter gasification, have sample segment to there is retention problems in pipeline.
Utility model content
The technical problem to be solved in the utility model anti-retention structure of sampling line be to provide in a kind of LNG on-line period system overcomes in prior art because LNG sampling system stop valve is excessive, the problems such as the vaporization rate deficiency of low power gasifier and sampling line connection, after causing LNG to enter gasification, sample segment in pipeline, is had to there is the defect of being detained.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: the anti-retention structure of sampling line in a kind of LNG on-line period system, comprise sampling line, electric heating gasification device, first flow variable valve, described electric heating gasification device and first flow variable valve are arranged on sampling line successively.
The beneficial effects of the utility model are: owing to increasing electrical heating pressurizing valve, variable valve in sampling line, for realizing the flow controlling sampling line LNG in pipeline, prevent the system that LNG is detained in pipeline.
On the basis of technique scheme, the utility model can also do following improvement.
The anti-retention structure of sampling line in the utility model a kind of LNG on-line period system described above, further, the sampling line after described first flow variable valve is also provided with surge tank.
The above-mentioned further beneficial effect of the utility model employing is: owing to increasing surge tank on LNG sampling line, the sample after gasification is mixed again, the heavy constituent atomization that may exist.
The anti-retention structure of sampling line in the utility model a kind of LNG on-line period system described above, further, described surge tank sampling line below is also provided with kapillary electric heating gasification device, second adjustable valve successively.
Adopt above-mentioned further beneficial effect to be: the pipeline after first time gasification increases by 2 flow control valves and a gasifier, ensure to make the LNG of gaseous state again mixed sample be transported to sampling cabinet with stable flow.
The anti-retention structure of sampling line in the utility model a kind of LNG on-line period system described above, further, also comprise pressure unit, described pressure unit is arranged on the sampling line between described kapillary electric heating gasification device and second adjustable valve.
The anti-retention structure of sampling line in the utility model a kind of LNG on-line period system described above, further, the power of described electric heating gasification device and kapillary electric heating gasification device is 200W.
The beneficial effects of the utility model are: integrated two the electric heating gasification devices of the utility model, a surge tank and two variable valve, become the modular system that has heating, throttling, temperature control, sample after stop valve docks at the scene with rock gas, can come into operation, there is the features such as construction workload is few, construction cost is low, stable performance.
Accompanying drawing explanation
Fig. 1 is the anti-retention structure schematic diagram of sampling line in a kind of LNG of the utility model on-line period system.
In accompanying drawing, the list of parts representated by each label is as follows:
1, LNG sampling line, 2, electric heating gasification device, 3, first flow variable valve, 4, surge tank, 5, kapillary electric heating gasification device, 6, second adjustable valve, 7, pressure unit.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, the anti-retention structure of sampling line in a kind of LNG of the utility model on-line period system, comprise sampling line 1, electric heating gasification device 2, first flow variable valve 3, described electric heating gasification device 2 and first flow variable valve 3 are arranged on sampling line 1 successively.Sampling line after described first flow variable valve is also provided with surge tank 4.Described surge tank 4 sampling line below is also provided with kapillary electric heating gasification device 5, second adjustable valve 6 successively.The power of described electric heating gasification device 2 and kapillary electric heating gasification device 5 is 200W.
The anti-retention structure of sampling line in a kind of LNG of the utility model on-line period system, another kind of concrete embodiment also comprises pressure unit, and described pressure unit 7 is arranged on the sampling line between described second electric heating gasification device and second adjustable valve.The principle of work of the present embodiment LNG anti-retention structure in sampling line is: the pressure of period of unloading a ship is 2.0bar, period can fluctuate up and down because unloading a ship working condition change, through the first heating gasifying device, sample after gasification enters surge tank through the first variable valve and again mixes, after being transported to the second electric heating gasification device uniformly, show the sample strain after its current gasification according to pressure unit, second adjustable valve adjusts mouth pressure flow according to pressure unit.
The kapillary electric heater that the utility model specific embodiment uses is TESCOM electric heater, and the first and second flow control valves are 44-5800 series.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
