Abstract
The utility model discloses a kind of exhaust funnel that refuels, it is characterized in that described funnel outer wall is fluted, described groove is from funnel end opening to funnel spiral extension suitable for reading, described inner wall of hopper has breather pipe, described breather pipe is communicated to inner wall of hopper top bottom inner wall of hopper, described groove is many, equidistantly arranges.When refueling, application the utility model can realize refueling and container is outwards vented and carries out simultaneously, guarantee container internal and external pressure balance, realize stable adding speed oil, avoid the generation of fuel injection event, promote and refuel efficiency, shorten refueling time, this device simple structure is practical, makes simple.
Description
Technical field
The utility model belongs to oiling field, relates to a kind of refueling unit device of air.
Background technology
Voltage transformer, due to long-time use, there will be the petrol starvation because a variety of causes causes often.By conventional funnel when refueling to voltage transformer, because voltage transformer oil filling port is less, funnel rim of a cup frame is placed on oil filling port, be blinded by oil filling port, only leave bell mouth, and funnel lower port is less, while oiling, installation for transformer internal gas outwards can only be vented from bell mouth, namely filling passage and exhaust passage share bell mouth, when gas is discharged, the speed that oil can be caused to flow into conservator slows down, extend refueling time, when installation for transformer internal gas can not be discharged in time, conservator internal pressure can be caused to increase, oil is caused to flow into conservator, when installation for transformer internal gas cannot discharge pressure increase to a certain degree time, often there is fuel injection event, transformer oil can be sprayed onto with it staff, therefore the work-hours that refuels also extends, and voltage transformer is generally unsettled, distance ground is higher, many more than 2 meters, during oiling, need staff's ascend operation, oil spout and long-time aloft work fatigue easily cause staff high-altitude to drop danger, inefficiency.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of exhaust funnel that refuels, and described funnel can steadily symmetry be positioned on voltage transformer oil filling port, refuels smooth and easy, and flow velocity is evenly quick, not oil spout.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of exhaust funnel that refuels, it is characterized in that described funnel outer wall has spiral groove, described spiral groove extends to the upper outlet of funnel from funnel end opening.Because groove is spiral, therefore funnel steadily symmetry can be positioned over vessel port, during oiling, gas in container can enter from the groove port of funnel end opening, arrives the contact opening of funnel and container, be rejected to air from spiral recess outlet along spiral groove, ensure that container internal and external pressure balance, prevent air-resistance phenomenon from occurring, realize oiling smooth and easy steadily fast, the flow velocity of oil is even.
Further, described inner wall of hopper is provided with breather pipe, and described breather pipe is communicated to funnel from funnel bottom.Arranging breather pipe is that container provides another breather line, prevents that groove is too small or to block the exhaust that causes not smooth.
Further, described spiral groove extends to the top of funnel from funnel end opening.
Preferably, described spiral groove is many, equidistantly arranges.
Preferably, described breather pipe is India rubber tube, and described India rubber tube is adhered to inner wall of hopper, and it is suitable for reading that funnel is stretched out in the upper end of India rubber tube, and the lower end of India rubber tube flushes with funnel end opening.
The beneficial effect adopting technique scheme to produce is: described oiling exhaust funnel has filling passage and exhaust passage simultaneously, when described oiling exhaust funnel is placed on oil filling port, the gas in container can be got rid of by exhaust passage while refueling, make the equilibrium of pressure of container inside and outside, during oiling, oil flow velocity is even, not oil spout, promote oiling efficiency, shorten refueling time, this device simple structure is practical, makes simple.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Detailed description of the invention
Embodiment 1
A kind of exhaust funnel that refuels, the outer wall of funnel 1 has spiral groove 2, and spiral groove 2 is spirally extended to the upper outlet of funnel 1 from the end opening of funnel 1, and described spiral groove 2 has 3, equidistant symmetric offset spread.Oiling exhaust funnel is put into voltage transformer oil filling port, during oiling, oil is from bell mouth inflow transformer conservator, and the air in installation for transformer can discharge installation for transformer from the spiral groove 2 of funnel, be communicated with air, make the equilibrium of pressure of container inside and outside, during oiling, oil flow velocity is even, not oil spout, promote oiling efficiency, shorten refueling time, this device simple structure is practical, makes simple.
Embodiment 2
A kind of exhaust funnel that refuels, the outer wall of funnel 1 has spiral groove 2, spiral groove 2 is spirally extended to the suitable for reading of funnel 1 from the end opening of funnel 1, described spiral groove 2 has 3, equidistant symmetric offset spread, the inner wall of hopper of funnel 1 is provided with freeing pipe 3, and the suitable for reading of funnel 1 is stretched out in the upper end of freeing pipe 3, and the lower end of freeing pipe 3 flushes with the end opening of funnel 1.Oiling exhaust funnel is put into voltage transformer oil filling port, and during oiling, oil is from bell mouth inflow transformer conservator, and the air in installation for transformer can discharge installation for transformer from the spiral groove 2 of funnel, is communicated with air; Also can enter from the lower port of freeing pipe 3, enter air via freeing pipe 3.Described freeing pipe 3 is India rubber tube, is adhered to funnel 1 inwall.Two kinds of ventilating modes make the equilibrium of pressure of container inside and outside, and during oiling, oil flow velocity is even, not oil spout, and promote oiling efficiency, shorten refueling time, this device simple structure is practical, make simple.
