Abstract
The utility model relates to an oil-draining and gas-discharging plug, belonging to the field of transformer manufacture technology and capable of being used for draining oil and discharging gas of oil-immersed type electric transmission and transformation equipment, such as an electric transformer, a reactor, a high-voltage switch and the like. The technical scheme is as follows: the oil-draining and gas-discharging plug comprises a plug seat (1), a metal plug (3), rubber pads (2) and protective covers (4), wherein the plug seat is arranged at the position of an opening of the electric transmission and transformation equipment; the metal plug is matched with the plug seat and the two are connected by threads; the plug seat and the metal plug are externally provided with the protective covers; and the rubber pads are arranged between the protective cover and the plug seat. The oil-draining or gas-discharging operation is finished, and then the protective covers and the rubber pads carry out secondary sealing on the oil-draining plug so as to prevent dust from polluting the plug; and in case that little leaked oil exists between the metal plug and the plug seat, the rubber pads and the protective covers can play a role of secondary sealing. If being aged or damaged, the rubber pads at the protective covers can be replaced with oil at any time, thus being extremely convenient. The oil-draining and gas-discharging plug has the characteristics of reasonable structure, reliable sealing, simple and convenient operation and the like.
Description
Affiliated technical field:
The utility model relate to a kind ofly drain the oil, air relief cock, belong to technical field of transformer manufacturing, can be respectively applied for oil immersed type power transmission and transforming equipments such as power transformer, reactor, high-voltage switch gear and drain the oil and exit.
Background technology:
When oil immersed type power transmission and transforming equipments such as power transformer, reactor, high-voltage switch gear are drained the oil and are exitted, some is lower than more residual insulating oils of position meeting of fuel outlet, thoroughly discharging is clean for the insulating oil that these are residual, needs in the minimum point at these positions bleeder plug to be installed.When these power transmission and transforming equipments are installed oilings or in the middle of the operation, some is higher than in the rising seat of exhaust outlet and the pipeline can gather some gases, for these gaseous emissions totally being avoided the safe operation of the equipment that influences, needs at these positions air relief cock to be installed.Existing bleeder plug and air relief cock all are with rubber blanket or the sealing of rubber seal ring between metal threaded plug and obturating plug, in case rubber blanket or rubber seal ring are broken, can cause insulating oil leakage, can not change and repair before these power transmission and transforming equipments power failures are drained the oil, widget causes burden.And after the sealing rubber blanket of usefulness or rubber seal ring are aging, can produce slight oil impregnate, though do not influence equipment operation, the insulating oil that oozes out very easily is infected with dust, influences the outward appearance of equipment.
The utility model content:
The utility model purpose provides and a kind ofly drains the oil, air relief cock, and sealing is reliable, and is simple to operation, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
Drain the oil, air relief cock comprises obturating plug, metal closures, rubber blanket, guard shield, obturating plug is arranged on the tapping of power transmission and transforming equipment, metal closures and obturating plug coupling are threaded each other, on obturating plug, outside the metal closures guard shield are set, and are provided with rubber blanket between guard shield and the obturating plug.
The part that air relief cock comprises is identical with bleeder plug, and just its obturating plug upper side has the aperture of a venting usefulness.
The utility model is screwed into the obturating plug metal closures and seals at the tapping welding obturating plug of power transmission and transforming equipment, and rubber blanket and guard shield play secondary seal and protective effect.
When equipment normally moved, threaded metal stopper was screwed into obturating plug, sealed with the aperture of the tight obturating plug in the conical points crown of metal closures, and insulating oil can not flow out.When needs are drained the oil, earlier guard shield is screwed down from obturating plug, again metal closures is screwed down from obturating plug, insulating oil flows out from obturating plug, drains the oil again metal closures to be tightened after finishing to seal, and uses protective cover and rubber blanket with the bleeder plug secondary seal at last.If venting, then metal stopper is unclamped but do not screw down, when metal stopper falls back on the position of air vent of obturating plug upper side, having gas ejects from air vent, stop the rotation of metal closures this moment, discharge when having only insulating oil to flow out when no longer including gas in the air vent, tighten metal closures again and reseal.
Drain the oil or bleed air operation finish the back with guard shield and rubber blanket with the bleeder plug secondary seal, prevent the pollution of dust to stopper, just in case slight oil impregnate is arranged between metal closures and the obturating plug, rubber blanket and guard shield can play the effect of secondary seal.If the rubber blanket at guard shield place is aging or damaged, can be with oil to change at any time, very convenient.
The utlity model has characteristics such as rational in infrastructure, that sealing is reliable, simple to operation.
