Abstract
A multifunctional fast pumping oil drainer for oil transportation pipelines is applied to the repair and reconstruction process of oil field oil transportation pipelines. An oil pumping pipe penetrates through the center hole of a housing; a sealing rubber sleeve is arranged in the sealing groove of the housing; a disc-shaped gland is fixed to the upper end face of the housing through a bolt; a gas guide center hole is formed in the lower end of the housing; transverse holes are symmetrically formed on the outer wall of the housing and communicated with the gas guide center hole; gas inlet control valves are fixed to the outer ends of the two transverse holes through screw threads, respectively; a three-way joint is connected to the top of the oil pumping pipe through screw threads; and a screwed plug is fixed to the other pass-through end connection of the three-way joint through screw threads. The multifunctional fast pumping oil drainer has the following advantages that: the oil drainer is inserted into an operation hole formed in the oil pumping pipeline, and oil pumping operation by using an oil pump is employed or a plurality of different operation manners such as oil draining operation by using compressed air or by filling nitrogen to cause pressure are employed, thereby accomplishing clearing of accumulated oil in the pipeline.
Description
Technical field
The utility model relates to oil field oil transport pipeline technical field, and the special tool of pump drainage oil usefulness in particularly a kind of oil transport pipeline repairing transformation process is the multi-functional quick pump drainage oil device of a kind of oil transport pipeline.
Background technique
At present; In oil transport pipeline main line, stand a repairing or general overhaul or transformation pipeline construction; Traditional oil extraction mode is on pipeline, to leave an oil pumping also need leave a tonifying Qi sky in other position in the hole, and is for thoroughly that oil product discharging in the pipeline is clean, needs sometimes even also that the side carry out the perforate oil extraction under pipe; Still need open a tonifying Qi hole again during oil extraction; This kind operating type perforate quantity is many, difficulty big, operating risk increases, the time is long, workload is big, and oil product relies on and puts from pressure in the pipeline, in actual job, often a tool oil trap need be set below oil drain out; Oil product in the pipeline is disposed in the oil trap, re-uses the pumping unit secondary and change other containers over to.
The model utility content
The purpose of the utility model is: provide a kind of oil transport pipeline multi-functional quick pump drainage oil device; According to pump drainages such as trunk pipeline and station repairing, general overhaul transformation oil operation process and practical application; Treat the trapped fuel in the oil transportation pipeline section of operation with quick cleaning; Practice thrift the first-aid repair construction time, alleviate the work operations amount.
The technological scheme that the utility model adopts is: the multi-functional quick pump drainage oil device of oil transport pipeline; Mainly form by housing, gland, sealing rubber cover, air intake control valve, oil pick-up tube and threeway; It is characterized in that: housing has center hole for the cylinder bodily form, in the housing center hole, is installed with an oil pick-up tube; There is the circular seal groove upper end of housing, in the seal groove of housing, sealing rubber cover is arranged, and sealing rubber cover is enclosed within on the outer wall of oil pick-up tube, through bolt a discoidal gland is arranged in the upper-end surface of housing, and gland compresses sealing rubber cover; There is the air guide center hole lower end of housing, and symmetry has transverse holes on the outer wall of housing, and transverse holes is communicated with the air guide center hole, is fixed with an air intake control valve in the outer end of two transverse holes respectively through screw thread; Through the threeway that has been threaded, the straight-through end interface of threeway is connected the top of oil pick-up tube at the top of oil pick-up tube; The straight-through end interface of another of threeway is fixed with a plug through screw thread; The plug of outwarding winding can insert probe and also pass oil pick-up tube, probe ability, liquid depth in the pipelines in the threeway always.
The working principle of the multi-functional quick pump drainage oil device of summary oil transport pipeline.Consult Fig. 1.One, when carry in the pipeline oil product utilize its from press Lee with pipeline in oil product be disposed to liquid level and can't rely on when pressure is put, quick pump drainage oil device is directly installed on the perforate pipe nipple.The bolt 4 of outwarding winding is regulated oil pick-up tube 6 extrusions, is advisable at the bottom of contacting transport pipe with oil pick-up tube 6, and tighting a bolt 4 is that gland 2 compresses sealing rubber cover 3, prepares the operation of pump drainage oil.Because oil pick-up tube 6 can be inserted pipeline depth according to the transport pipe diameter adjustment, can oil pick-up tube 6 directly be inserted the oil transport pipeline bottom, adjust the bolt 4 of screwing and compress gland 2, sealing rubber cover 3 and oil pick-up tube 6 are combined closely, realize sealing.Two, when utilizing pumping units such as Roots's oil pump or diaphragm pump to pump, directly be connected the pump inlet end on the connection mouth 8 of threeway through flexible pipe; Because oil transport pipeline is a confined space, during the operation of beginning pump drainage oil, housing 1 two ends air intake control valve 5 is opened; Tonifying Qi in pipeline; Regulate air intake control valve 5 control oil drain quantities, avoid pipeline negative pressure to occur and cause oil extraction not smooth, can oil product pump drainage in the oil transport pipeline is clean.Three, when the job site condition does not possess the pumping unit oil pumping; Nitrogen capable of using or compressed-air line are connected on the air intake control valve 5 of housing 1 both sides; Air intake pressurized in oil transport pipeline; This moment, suction pressure acted directly on the interior oil product liquid level of oil transport pipeline, because pressurization can directly give off pipeline with oil product in the pipeline.Four, behind pump drainage oil end-of-job, the plug 9 of threeway 7 upper ends of outwarding winding, the stock rod that directly probe is inserted in the threeway 7 inserts in the mouth, surveys liquid depth in the oil transport pipeline.
The beneficial effect of the utility model: the multi-functional quick pump drainage oil device of the utility model oil transport pipeline; Insert in the operation hole of leaving on the pumping pipelines; Use oil well pump oil pumping operation or use pressurized air, nitrogen to annotate multiple different operating types such as pressure oil operation, accomplish the trapped fuel in the clearing of pipeline.A covering device can satisfy the pump drainage oil operation of each specification pipeline of DN100 to DN800 simultaneously.Do not need large-scale pumping units such as Roots's oil pump when using this device pump drainage oil operation, reduced repairing operation collection and pretended industry time and recovery vehicle, facility outfit requirement.Average each job step is saved 2.5 hours in dimension repairing operation process.This apparatus structure compactness, good seal performance, make pipeline and extraneous hermetic barrier.
