Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
The oil storage system of a kind of non-minimum point mass flow measurement as shown in Figure 1, this unloading port of system 1, oil transport pipeline, discharge pump 2, mass flowmenter 7 and oil storage tank 13, described oil storage tank 13 is positioned at the system pipeline minimum point, discharge pump 2 has two, two discharge pumps 2 are in parallel (the using and the reserved), and unloading port 1 connects discharge pump 2, mass flowmenter 7 and oil storage tank 13 by oil transport pipeline.As shown in Figure 1, be connected with the first air separator 3 in the rear end of discharge pump 2, the rear end of the first air separator 3 arranges described mass flowmenter 7 at the local low point oil transport pipeline, the two ends of mass flowmenter 7 are respectively arranged with first and switch shutoff valve 6 and the second switching shutoff valve 8, the second switching shutoff valve 8 is connected with the second air separator 10, the second air separators 10 and is connected to described oil storage tank 13.Also be provided with collateral branch's oil transport pipeline between the first air separator 3 and the second air separator 10, collateral branch's oil transport pipeline is in parallel with mass flowmenter 7, is provided with the 3rd at collateral branch's oil transport pipeline and switches shutoff valve 9, is convenient to the flowmeter maintenance.And at the relief opening of the first air separator 3 and the second air separator 10 oil plant collecting box 4,11 is installed respectively, the small part oil plant of taking out of when collecting the relief opening exhaust is respectively equipped with flow-off 5,12 on the oil plant collecting box 4,11.
At ordinary times not during emptying discharge pump 2 stop, the first air separator 3 and second row air valve 10 are opened, oil plant collecting box 4,11 is in the empty van state, the 3rd switches shutoff valve 9 closes, the first switching shutoff valve 6 and second switches shutoff valve 8 to be opened, and is full of liquid state oiling (diesel oil) in the mass flowmenter 7.
Open as required wherein one of discharge pump 2 during emptying, oil plant is drawn into discharge pump 2 from RTC unloading mouth 1 by pipeline, by getting to the first air separator 3 after discharge pump 2 pressurizations, in the first air separator 3, form gas-liquid two state spaces, the first air separator 3 outlet valves are in open mode, drive ball float rising in the first air separator 3 in gas-liquid two state spaces on the liquid level along with oil inlet quantity strengthens, gas is discharged from, and liquid level continuation rising ball float rises thereupon and closes the first air separator 3 outlet valves.Liquid diesel stream behind the elimination bubble switches shutoff valve 6 by pipeline local low point mass flowmenter 7 through first, rises by the second switching shutoff valve 8 with pipeline, enters the second air separator 10.Outlet valve was closed in the ball float rising after the second air separator 10 was got rid of gas in pipelines, and liquid diesel oil flows to system's minimum point oil storage tank 13 through transport pipe in the pipeline.
The small part air can enter oil transport pipeline through unloading port 1 during emptying, air gas-liquid separation during through the first air separator 3, gas rising gaseous space strengthens liquid level decline in the first air separator 3 interior gas-liquid two state spaces, ball float descends thereupon, descend and to a certain degree open afterwards the first air separator 3 outlet valves, discharge air.Then continue oil-feed and drive ball float rising in the first air separator 3 in gas-liquid two state spaces on the liquid level along with oil inlet quantity strengthens, gas is discharged from, and liquid level continuation rising ball float rises thereupon and closes the first air separator 3 outlet valves.
Oil plant collecting box 4,11 is collected respectively the small part liquid diesel of being taken out of by gas when the first air separator 3 of correspondence and 10 exhaust of the second air separator, flow-off 5,12 plays the overflow effect when oil plant collecting box 4,11 oil plant liquid levels are full.If emptying the 3rd switching shutoff valve 9 is opened when flowmeter overhauls, close first and switch shutoff valve 6 and the second switching shutoff valve 8, liquid diesel oil does not switch shutoff valve 6 and second by first and switches shutoff valve 8 and mass flowmenter 7 pipelines through the 3rd stop valve valve 9.
Discharge pump 2 cuts out when stopping emptying, liquid diesel oil is sucked into oil storage tank 13 because of siphonage in the air separator 10 rear pipelines, air separator 10 interior liquid levels descend, ball float descends thereupon, descend and to a certain degree open afterwards air separator 10 outlet valves, the liquid diesel oil of oil plant collecting box 11 interior collections can be by in the intake line slowly, and air enters behind the second air separator 10 in the pipeline through the second air separator 10 outlet valves, and the low pipeline in the second air separator 10 front parts flowmeter 7 interior liquid diesel oil of improving quality still keep full packages.Simultaneously because manifold pressure the first air separator 3 interior liquid levels that descend descend, ball float descends thereupon, descend to a certain degree opening afterwards the first air separator 3 outlet valves, the liquid diesel oil of oil plant collecting box 4 interior collections because of the liquid level high pressure greater than pipeline, can slowly be flow in the pipeline.Final the first air separator 3 and the second air separator 10 outlet valves all return to and do not unload at ordinary times oil condition is open mode, and oil plant collecting box 4,11 is in the empty van state.
By above-mentioned mode of execution, the flowmeter full packages of ensuring the quality of products is measured, and reaches accurate measurement purpose, reduces unnecessary economic loss.
