Description
[affiliated technical field]
The utility model relates to a kind of adapter assembly, especially belongs to the power transformer transport pipe coupling assembly that a kind of auxiliary transformer oil transport pipeline and oil transport pipeline are coupled to each other usefulness.
[background technique]
Transformer is a kind of power equipment of electric substation's extensive use, therefore giving the transformer makeup oil in installation, annual test and the overhaul process is a day-to-day work of power engineering unit, because the particularity of electric power facility, requirement to transformer oil oil is quite high, if before and after oiling and in the withstand voltage experiment chemical examination, find that oil does not meet standard, dropping into lot of manpower and material resources with regard to needs comes slops is filtered, therefore, not only can delay the power construction duration directly influence putting into operation of electric substation, also can stay potential safety hazard to the operation of whole electrical network.In the prior art; when running into duct length when not enough for the transformer oil transportation with oil transport pipeline; owing to there is not suitable coupling assembly; adopt the mode of iron pipe and rubber tape colligation butt joint through regular meeting; time-consuming, sealing is poor, causes the pollution and the seepage of transformer oil easily, be difficult to guarantee transformer oil oil; in addition, also can directly influence application of vacuum, pump-down time, oil injecting speed, the vacuum range of transformer.
[summary of the invention]
For solving the above-mentioned problems in the prior art, the utility model aims to provide a kind of power transformer transport pipe coupling assembly, can realize connecting between transport pipe and the transport pipe easily by this coupling assembly, advantage with good seal performance, thereby guarantee transformer oil oil, the degree of purity carried, effectively improve oil transportation efficient, help eliminating the potential safety hazard of electric power facility.
The technological scheme that its technical problem that solves the utility model adopts is: the structure outline of this power transformer transport pipe coupling assembly is: it is made of two attaching nuts, two oil connections and a dustproof connecting head, dustproof connecting head is the barbell shape, axially symmetrical, axis is a pipe, the pipe end forms step, and the step outer ring surface has outside thread; Two oil connections lay respectively at dustproof connecting head both sides, and the oil connection axial shape is the step tubular, and the tubular afterbody has a connection buckle of admitting dustproof connecting head pipe end, and the external diameter and the externally threaded end of step outer ring surface that connect buckle directly are complementary; Two attaching nuts lay respectively at the dustproof connecting head outside, have the internal thread that is complementary with dustproof connecting head pipe outside thread on attaching nut's the internal ring wall, step in forming after attaching nut's the outlet reducing.
Aforesaid a kind of power transformer transport pipe coupling assembly, it is characterized in that: the external annulus of the tubular front portion of oil connection is provided with the oil pipe draw-in groove.
Aforesaid a kind of power transformer transport pipe coupling assembly, it is characterized in that: attaching nut's ring wall is provided with the degree of tightness hole of annular spread.
Beneficial effect: also do not find this type of coupling assembly in the prior art, as with the accessory kit of power transformer, two transport pipe are nested with respectively on the oil connection at two ends by its mouth of pipe, fastening the back with snap ring again connects firmly, the oil pipe draw-in groove is set on the oil connection, and it is higher that the snap ring button is embedded in the oil pipe draw-in groove tightness.Admittedly be spun on the outside thread of dustproof connecting head with the attaching nut again, thereby realize two butt joints between the transport pipe.Because assembly adopts screw thread to spin, and is convenient and practical, all is provided with corresponding seal ring on the sealing surface of each parts, good seal performance, thus guaranteed transformer oil oil, degree of purity, help improving oil transportation efficient.
Below in conjunction with drawings and Examples the utility model is further specified.
[description of drawings]
Fig. 1 is an assembly structure schematic representation of the present utility model.
Sequence number is represented respectively among the figure: the attaching nut 10, degree of tightness hole 101, internal thread 102, interior step 103; Oil connection 20, oil pipe draw-in groove 201, draw-in groove bulge loop 202 connects buckle 203, annular cavity 204, transition cylinder 205; Dustproof connecting head 30, pipe end 301, outside thread 302, pipe 303.
[embodiment]
In Fig. 1, be respectively attaching nut 10, oil connection 20, dustproof connecting head 30, oil connection, attaching nut from left to right.Because the structure of two attaching nuts and two oil connections is identical, and dustproof connecting head 30 also is axial symplex structure fully, therefore, only tells one-sided symplex structure in following telling.
Middle dustproof connecting head 30 is the barbell shape, and axially symmetrical, axis is a pipe 303, and pipe end 301 exposes head, and forms a circular step, and the anchor ring of circular step is provided with outside thread 302.
It is step-like that oil connection 20 outer wall axial shape are tubular, constitutes by connecting the slightly little transition cylinder 205 of buckle 203, external diameter and the anterior pipe of external diameter minimum from right to left.Connect buckle 203 external diameter maximums, its annular cavity 204 has a step of admitting seal ring (not drawing among Fig. 1), and assembling back sealing circle just in time is positioned on the step of pipe end 301 of dustproof connecting head 30 pipes 304, plays seal action.The anterior pipe outer ring surface of the oil connection 20 of external diameter minimum is provided with oil pipe draw-in groove 201, in order to ensure docking with the sealing of transport pipe, oil pipe draw-in groove 201 can be established several roads more, the middle part with draw-in groove bulge loop 202 at interval, during use, the transport pipe mouthpiece cover is stuck in the oil pipe draw-in groove 201 with card article then to the base portion of the anterior pipe of oil connection 20, guarantees sealing.
Attaching nut 10 is the parts with a through hole, and the inner ring wall in its left side inwardly ring convexes into an interior step 103, and step 103 mainly plays with the outer wall that is connected buckle 203 and realizes fastening bit pairing in this.Interior step 103 internal ring wall to the right is provided with internal thread 102, and this internal thread 102 can spin with outside thread 302, screws the back and guarantees that under the effect of seal ring oil connection 20 docks with the sealing of dustproof connecting head 30.Attaching nut 10 ring wall is provided with degree of tightness hole 101, and degree of tightness hole 101 is a through hole, therefore, is the outside of preferably depending on attaching nut 10 in setting, to improve sealing effect.
Contrast Fig. 1 tells assembly process below, to deepen understanding of the present utility model.
Seal ring is inserted on annular cavity 204 sealing surfaces that connect buckle 203 earlier, attaching nut 10 is inserted in oil connection 20, and make on the step of pipe end 301 of pipe 303 of the dustproof connecting head 30 of annular cavity 204 butt joints that connects buckle 203, make attaching nut 10 fastening by internal thread 102 and outside thread 302, finish oil connection 20 with this and dock with the sealing of dustproof connecting head 30.
