Abstract
The utility model discloses a transformer explosion-proof fuel drainage valve, comprising a valve, an oil exit pipe, an oil pipe flange and a transformer fuel tank; the oil exit pipe is fixedly arranged on one side of the lower part of the transformer fuel tank; the intermediate part of the oil exit pipe is provided with the valve; a terminal end of the oil exit pipe is provided with the oil pipe flange, the outer wall of which is provided with a glass plate; the glass plate is fixed between a glass fixing flange and the oil pipe flange by glass fixing bolts and the glass fixing flange, which can effectively prevent transformer oil from leakage from a fuel drainage valve and avoid safety environmental accidents; when an accident happens to the transformer and emergent oil drainage is needed, the transformer explosion-proof fuel drainage valve can realize rapid oil drainage, and reduce the equipment damage degree in a state of accidents.
Description
Technical field
The utility model belongs to transformer oil discharging valve control technology field.
Background technology
The transformer fuel outlet valve be transformer regularly draw oil sample and accident conditions under the passage of draining the oil.Present oil discharging valve is made of valve runner, valve bolt, valve flanges, oil exit pipe etc.The leakage of oil of operating transformer fuel outlet valve ubiquity valve, oil impregnate phenomenon, the transformer oil that spills is contaminated environment not only, and has potential safety hazard, particularly breaks down when catching fire when transformer, can not operate oil discharging valve fast and bleed off oil in the transformer, enlarge the degree of injury of equipment.
The utility model content
The purpose of this utility model provides and a kind ofly can prevent the valve leakage of oil, and in case of emergency bleeds off the explosion-proof oil discharging valve of transformer of transformer oil fast.
To achieve these goals, the utility model comprises: valve, oil exit pipe, oil pipe flange, oil tank of transformer, oil exit pipe is fixedly installed on transformer oil lower box part one side, in the middle of oil exit pipe, be provided with valve, be provided with the oil pipe flange in the oil exit pipe termination, it is to be provided with glass plate at oil pipe flange outer wall, utilizes glass fastening bolt and glass mounting flange that glass plate is fixed between glass mounting flange and the oil pipe flange.
Described glass plate both sides are respectively arranged with the oil resistant seal gasket, to prevent the glass plate place leakage of oil take place.
Like this, when transformer normally moves, can prevent effectively that transformer oil from spilling from the valve port of draining the oil, avoid the generation of safety and environmental protection accident; When transformer occurs cracking glass plate when accident need promptly be drained the oil, or glass plate be heated the nature fragmentation (because of glass different with the thermal coefficient of expansion of metal), oil discharging valve just can be realized draining the oil fast, the degree of injury of equipment under the reduction accident condition.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises: valve 1, oil exit pipe 2, oil pipe flange 3, oil tank of transformer 8, oil exit pipe 2 are fixedly installed on oil tank of transformer 8 bottoms one side, are provided with valve 1 in the middle of oil exit pipe 2, are provided with oil pipe flange 3 in the oil exit pipe termination.Be provided with glass plate 6 at oil pipe flange 3 outer walls, utilize glass fastening bolt 5 and glass mounting flange 4 that glass plate is fixed between glass mounting flange 4 and the oil pipe flange 3.Glass plate be circle and diameter greater than the oil exit pipe diameter, glass mounting flange and oil pipe flange diameter are should size consistent and greater than the glass plate diameter.Glass plate 6 both sides are respectively arranged with oil resistant seal gasket 7, with the sealing reliability that guarantees the glass plate place and reduce the pressure that glass plate is subjected to.
Claims (2)
