Technical field
This utility model belongs to oil and gas industrial technical field, particularly relates to a kind of railway and unloads station new type of safe
Unloading Device.
Background technology
Existing oil depot railway is unloaded and is stood in time trestle is carried out Process Planning, at oil discharge pipe, and existing peace
Fill common cut-out cock, the most easily cause string oil, tank car bleed or oil product between oil filling riser to unload the phenomenons such as the cleanest.Fig. 1 is
Example, the easy produced problem of trestle only installing common block valve is as follows:
1. assume oil depot railway unload station trestle organize Unloading Arm, if only installing common block valve, when there being a crane more
The oil-immersed pump of pipe does not works in the case of unwitting, and the oil product being easy for causing other oil filling riser oil-immersed pumps to pump is simultaneously to this groove
Car send oil, thus causes this tank car bleed.
2. in the case of normal emptying, due to uncertain factor (time difference started such as oil-immersed pump, or tank car appearance
Measure the situations such as not of uniform size), when a tank car oil product will be unsnatched wherein, if the ball valve under oil filling riser is closed not in time, also
Easily cause the oil product that other oil filling riser oil-immersed pumps pump and send oil to this tank car simultaneously, thus this tank car oil product occurred unloads the most existing
As, to cause emptying time-lag.
Therefore can oil filling riser be normally carried out loading and unloading oils process by safe emptying under there is not above-mentioned unexpected situation
Significance.
Utility model content
Technical problem to be solved in the utility model is, in order to effectively prevent oil sale industry from carrying out oil depot emptying
Alter oil, tank car bleed or oil product during operation between multiple oil filling risers and unload the generation of sordid phenomenon.
For solving the problems referred to above, the technical solution of the utility model is, a kind of railway is unloaded the safe Unloading Device in station, including
Organize oil filling riser, oil circuit pipeline and oil depot more；Described often group oil filling riser is connected with oil depot by oil circuit pipeline；Described oil filling riser and oil depot it
Between be provided with oil pump；It is parallel with on described same oil circuit pipeline and organizes oil filling riser more；It is provided with between described oil filling riser and oil circuit pipeline and cuts
Disconnected valve and check valve；Oil circuit is then passed through block valve and check valve by oil filling riser, then sequentially passes through oil pump arrival oil depot.
Further, the block valve of described oil filling riser and check valve two ends bypass line in parallel.
Further, described bypass line includes check valve and block valve.
Further, described oil circuit pipeline includes diesel oil pipe, No. 93 medium gasoline pipeline and No. 97 medium gasoline pipeline, described bavin
Oil pipeline, No. 93 medium gasoline pipeline and No. 97 medium gasoline pipeline are all connected in parallel on same group of oil filling riser.
Further, described oil filling riser is also parallel with gasoline and sweeps storekeeper line and storekeeper line swept by diesel oil.
Further, described gasoline is swept and is provided with gasoline sliding-vane pump on storekeeper line.
Further, described diesel oil is swept and is provided with diesel oil sliding-vane pump on storekeeper line.
The beneficial effects of the utility model: device makes simply, production cost is few；After oil filling riser installs block valve, stop oil
Product backflow, string oil, it is to avoid owing to backflow, string are by the fail-safe caused；Block valve and the check valve two ends of oil filling riser are in parallel simultaneously
Bypass line, pipeline is installed check valve and block valve successively, and this technological process can be used for hair oil operation；Many group oil filling risers can be simultaneously
Unloading diesel oil, No. 93 gasoline and three kinds of oil products of No. 97 gasoline, this technological process can be used not only for emptying operation it can also be used to send out
Oil operation, is independent of each other.During fundamentally solving Railway Trestle Bridge emptying, oil product flows back into tank car, tank car bleed and oil
Product unload sordid safety problem.

Fig. 3 is the unloading of this utility model embodiment, hair oil pipeline schematic diagram.
Detailed description of the invention
With specific embodiment, this utility model is further elaborated below in conjunction with the accompanying drawings.
The station new type of safe Unloading Device as in figure 2 it is shown, a kind of railway is unloaded, including organizing oil filling riser, oil circuit pipeline and oil more
Storehouse；Described often group oil filling riser is connected with oil depot by oil circuit pipeline；It is provided with oil pump between described oil filling riser and oil depot；Described same oil
It is parallel with on the pipeline of road and organizes oil filling riser more；Block valve and check valve it is provided with between described oil filling riser and oil circuit pipeline；Oil circuit passes through crane
Pipe is then passed through block valve and check valve, then sequentially passes through oil pump arrival oil depot.Oil circuit pipeline includes diesel oil pipe, No. 93 gasoline
Pipeline and No. 97 medium gasoline pipeline, described diesel oil pipe, No. 93 medium gasoline pipeline and No. 97 medium gasoline pipeline are all connected in parallel on same group
On oil filling riser.
Diesel fuel oil through oil filling riser, block valve, check valve, diesel oil pipe, diesel pump to diesel oil storehouse.
No. 93 oil product of gasoline are through oil filling riser, block valve, check valve, No. 93 medium gasoline pipeline, petrol pump to No. 93 petrol storages.
No. 97 oil product of gasoline are through oil filling riser, block valve, check valve, No. 97 medium gasoline pipeline, petrol pump to No. 97 petrol storages.
As in figure 2 it is shown, the installation of above-mentioned check valve, it is to avoid oil product through oil collecting pipe, block valve flow to another oil filling riser (or
Tank car) generation of accident, also stopped the event that in single oil filling riser, oil product refluxes through block valve simultaneously.Some oil filling riser is prevented to dive
When oil pump quits work, the oil product that other oil filling riser oil-immersed pumps are pumped send oil to this tank car simultaneously, causes this tank car to emit oil condition.
In addition it also avoid when tank car oil product will be unsnatched ball valve under oil filling riser to close not in time, cause other oil filling riser oil-immersed pumps to pump
Oil product send oil to this tank car simultaneously, occurs that this tank car oil product unloads sordid phenomenon.
Also it is parallel with gasoline on oil filling riser and sweeps storekeeper line and storekeeper line swept by diesel oil.Described gasoline is swept and is provided with vapour on storekeeper line
Oil sliding-vane pump.Described diesel oil is swept and is provided with diesel oil sliding-vane pump on storekeeper line.Remaining oil product in oil filling riser sweeps storekeeper by diesel oil
Line or gasoline are swept in the oil return tank that correspondence collected under the effect of gasoline sliding-vane pump or diesel oil sliding-vane pump by storekeeper line.
As it is shown on figure 3, in the new type of safe oil transferring device that can be used for emptying and hair oil, based on Fig. 2, again at oil filling riser
Block valve and check valve two ends are in parallel bypass line, pipeline includes check valve and block valve.Close during hair oil and bypass with this
The block valve in unloading line that pipeline is in parallel, opens the block valve on this bypass line simultaneously, starts emptying.List on this pipeline
Oil product can be avoided to reflux to the installation of valve.Many group oil filling risers can unload diesel oil, No. 93 gasoline and three kinds of oil products of No. 97 gasoline simultaneously,
It is independent of each other；This technological process can be used not only for emptying operation it can also be used to hair oil operation.Fundamentally solve Railway Trestle Bridge
During emptying, oil product flows back into tank car, and tank car bleed and oil product unload sordid safety problem.
Those of ordinary skill in the art is it will be appreciated that embodiment described here is to aid in this reality of reader understanding
