The utility model is related to a kind of Accident of Transformer draining valve new structure, belongs to technical field of transformer equipment.Technical scheme is：Oil exit pipe（9）One end be vertically set on transformer box wall（1）On, the other end of oil exit pipe is provided with flange one（6）, it is oriented to union（4）One end be provided with flange two（7）, butterfly valve（3）It is arranged on flange one and flange two（7）Between, flange one, butterfly valve is crossed bolt and is fixedly connected with flange two-way；The guiding union（4）It is arc, the other end for being oriented to union is provided with cover plate（5）, cover plate（5）With transformer box wall（1）It is mutually perpendicular to.The utility model opens, close and need to be only rotated by 90 ° Handle of butterfly valve with spanner, and compared to the rotation of gate valve, a few are efficient and convenient.Drained the oil by only cover plate need to be broken into pieces, greatlyd save time and the step of operation, risk is preferably minimized.Can effectively ensure that oil extraction direction vertically downward, prevent the phenomenon outside horizontal oil spout to oil sump.
Description
Technical field
The utility model is related to a kind of Accident of Transformer draining valve new structure, belongs to technical field of transformer equipment.
Background technology
Typically using the cast iron gate valve of finished product, regular size has φ 100, φ 125, φ to traditional Accident of Transformer draining valve
150 etc..After transformer generation accident, to be drained the oil by the accident draining valve of lower oil tank, need to dismantle gate valve protection cap
Plate, rotation hand wheel opens gate valve.Gate valve hand wheel stroke is universal more long, and oil extraction direction is horizontal cross, if oil pressure in transformer
Larger, transformer oil easily sprays oil sump and causes ground pollution.
Utility model content
The purpose of this utility model is to provide a kind of Accident of Transformer draining valve new structure, overcomes and uses traditional gate valve
The drawbacks of, realize orientation oil extraction, it is ensured that transformer oil is discharged into oil sump, without external contamination；Open operation more efficient and convenient, more
Transformer body is protected well, solves the above mentioned problem that background technology is present.
A kind of Accident of Transformer draining valve new structure, comprising transformer box wall, transformer tank bottom, butterfly valve, be oriented to union,
Cover plate, flange one, flange two, seal washer and oil exit pipe, the transformer box wall are vertically set on transformer tank bottom
Top, one end of oil exit pipe is vertically set on transformer box wall, and another end interface of oil exit pipe is flange one, is oriented to union
One end is provided with flange two, and butterfly valve is arranged between flange one and flange two, and flange one, butterfly valve and flange two-way are crossed bolt and fixed and connect
Connect；The guiding union is arc, and the other end for being oriented to union is provided with cover plate, and cover plate mutually hangs down with transformer box wall
Directly, it is provided with seal washer between the other end of cover plate and guiding union.
The guiding union is bent downwardly 90 degree.
The flange one and flange two are circular steel plate flange.
Oil extraction end replaces steel plate cover plate to block with glass material.
Good effect of the present utility model：First, using butterfly valve, good seal performance, long service life are opened, closed only
Handle of butterfly valve need to be rotated by 90 ° with spanner, compared to the rotation of gate valve, a few are efficient and convenient.Second, traditional gate valve is needed before opening
Fastening bolt is turned on spanner, the cover plate of end is removed, taken some time；And the utility model need to only strike cover plate
It is broken to be drained the oil, when burst emergency is run into, time and the step of operation are greatlyd save, risk is dropped to most
It is low.3rd, it is oriented to union and can effectively ensure that oil extraction direction vertically downward, prevent the phenomenon outside horizontal oil spout to oil sump.The
Four, relative because there is the finished product gate valve that expose screw rod and cannot paint again, accident draining valve of the present utility model can be become by original
Depressor it is flexible carry out color matching spray painting, it is in global consistency and even better in appearance, the 5th, it is close with seal washer
Envelope, plays a part of antifouling, dust-proof, anti-toy.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
In figure：Tank wall 1, bottom 2, butterfly valve 3, be oriented to union 4, cover plate 5, flange 1, flange 27, seal washer 8,
Oil exit pipe 9.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples：
A kind of Accident of Transformer draining valve new structure, comprising transformer box wall 1, transformer tank bottom 2, butterfly valve 3, guiding connection
Pipe 4, cover plate 5, flange 1, flange 27, seal washer 8 and oil exit pipe 9, the transformer box wall 1 are vertically set on change
The top of depressor bottom 2, one end of oil exit pipe 9 is vertically set on transformer box wall 1, and another end interface of oil exit pipe 9 is method
Blue 1, the one end for being oriented to union 4 is provided with flange 27, and butterfly valve 3 is arranged between flange 1 and flange 27, flange one 6, butterfly valve
3 and flange 27 be bolted to connection；The guiding union 4 is arc, and the other end for being oriented to union 4 is provided with cover plate
5, cover plate 5 is mutually perpendicular to transformer box wall 1, and seal washer is provided between the other end of cover plate 5 and guiding union 4
8。
The guiding union 4 is bent downwardly 90 degree.
The steel plate 1 and steel plate 27 are circular steel plate.
The cover plate 5 is fixed using steel plate trim ring by fastening bolt, and there is seal gasket both sides.
Open, need to only be rotated by 90 ° for Handle of butterfly valve with spanner by closing, and sealing glass breaking can be drained the oil, lead
Oil extraction direction is can effectively ensure that to union vertically downward, prevent the phenomenon outside horizontal oil spout to oil sump.
