Description

Transformer respirator connecting device

Technical Field

The utility model relates to the technical field of disassembly and assembly of transformer respirators, in particular to a transformer respirator connecting device.

Background

As shown in figure 1, the flange of the existing transformer respirator 6 is directly connected with the flange of the conservator breathing tube 5, so that the disassembly and assembly are inconvenient. Each time the disassembly and assembly are carried out by two persons, one person holds the respirator tank body, and the other person removes the bolts, so that the disassembly and assembly of the bolts are time-consuming and labor-consuming. Replacement of the respirator is a relatively frequent task, and thus there is a need for improvements in the manner in which the respirator is replaced.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a transformer breather connecting device which can quickly complete the replacement of a transformer breather.

In order to solve the technical problems, the utility model adopts the following technical scheme: a transformer breather connecting device comprises an upper connecting part and a lower connecting part which are connected in a screwed mode;

the upper connecting part comprises an upper connecting pipe which is used for being connected with a breathing pipe of the transformer oil pillow;

the lower connecting part comprises a lower connecting pipe which is used for being connected with the respirator;

the upper connecting part is screwed with the lower connecting part, and then the upper connecting pipe is tightly connected with the lower connecting pipe.

Preferably, the side walls of the upper connecting pipe and the lower connecting pipe are provided with a buckle and a limiting ring for screwing, the inner side of the buckle is provided with a limiting groove, and the limiting groove is matched with the limiting ring.

Preferably, the limiting ring extends in the rotation direction, and the thickness of the limiting ring is gradually increased, so that the limiting groove is used for tightly pressing the upper connecting pipe and the lower connecting pipe.

Preferably, a lock catch for preventing the upper connecting part and the lower connecting part from rotating relatively is arranged on the outer side of the buckle.

Preferably, the upper end of the upper connecting pipe is provided with an upper flange plate for being connected with a breathing pipe flange, and the lower end of the lower connecting pipe is provided with a lower flange plate for being connected with a respirator flange.

Preferably, the lower end of the upper connecting pipe and the upper end of the lower connecting pipe are provided with sealing ring mounting grooves for placing rubber sealing rings.

The utility model provides a transformer respirator connecting device, which has the following advantages: 1. the respirator is replaced without disassembling bolts, so that time and labor are saved; 2. replacement of the respirator may be accomplished by a single person; 3. can be improved on the existing respirator without changing the original equipment.

Detailed Description

As shown in fig. 2 and 3, a transformer respirator connecting device comprises an upper connecting part 1 and a lower connecting part 2 which are connected in a screwed mode;

the upper connecting part 1 comprises an upper connecting pipe 3, and the upper connecting pipe 3 is used for being connected with a breathing pipe 5 of a transformer oil pillow;

the lower connecting part comprises a lower connecting pipe 4, and the lower connecting pipe 4 is used for being connected with a respirator 6;

the upper connecting part 1 is screwed with the lower connecting part 2, and then the upper connecting pipe 3 is tightly connected with the lower connecting pipe 4.

Preferably, the side walls of the upper connecting pipe 3 and the lower connecting pipe 4 are provided with a buckle 7 and a limiting ring 8 for screwing, the inner side of the buckle 7 is provided with a limiting groove 9, and the limiting groove 9 is matched with the limiting ring 8.

Preferably, the thickness of the limiting ring 8 increases gradually along the rotation direction, so that the limiting groove 9 is used for pressing the upper connecting pipe 3 and the lower connecting pipe 4.

Preferably, a lock catch 10 for preventing the upper connecting portion 1 and the lower connecting portion 2 from rotating relatively is arranged on the outer side of the buckle 7.

Preferably, the upper end of the upper connecting pipe 3 is provided with an upper flange plate 11 for being connected with a breathing pipe flange, and the lower end of the lower connecting pipe 4 is provided with a lower flange plate 12 for being connected with a respirator flange.

Preferably, a seal ring mounting groove 13 for placing a rubber seal ring is arranged at the lower end of the upper connecting pipe 3 and the upper end of the lower connecting pipe 4.

When the breathing tube device is used, as shown in fig. 4, the breathing tube device is additionally arranged between the breathing tube 5 and the respirator 6 of the conservator, and the respirator can be detached only by opening the lock catch 10 and rotating the lower connecting part 2 when the respirator is detached. After the respirator is heated and dehumidified, the lower connecting part 2 is connected to the upper connecting part 1 in a screwing way, so that the installation of the respirator can be completed, and the disassembly and assembly can be completed by a single person, thereby greatly improving the efficiency.

The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
