Description
Technical field
The present invention relates to interim respirator.
Background technology
The effect of transformer breather silica gel and lubricating cup, silica gel is the water that filtering enters in the air of transformer oil capsule
Part, transformer oil sac is contacted with transformer oil for a long time, if water content is too high in air, easily accelerates the aging of oil capsule.Oil
The effect of transformer oil is that breathing mouth is lived with oil sealing in cup, prevents silica gel bump contact outside air and change of making moist rapidly
Color.When observing that silica gel changes colour more than 2/3 from bottom to top in transformer breather, it is necessary to report defect, operation maintenance personnel is arranged
Respirator silica gel replacing is carried out, grave gas are protected into the number of converting to during replacing.Silica gel is changed and requires fine, and humidity should not be too
It is high.A respirator silica gel is changed to generally require 30-40 minutes.After former respirator is pulled down, typically without special instrument by air guide
Pipe is sealed, and easily has humid air or foreign matter to enter transformer oil sac, causes oil capsule accelerated ageing.
The content of the invention
Problem to be solved by this invention is to provide interim respirator, is connected to pulling down when former respirator changes its silica gel
Wireway, it is to avoid wireway be directly exposed in air make moist or foreign matter entrance, it is quick and easy for installation.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：Interim respirator, including from top to bottom according to
The flange of secondary setting, upper lid, cylinder and lower cover, gas port is respectively equipped with the flange, Shang Gai and lower lid, and the cylinder is upper and lower
Through connection, the gas port on the flange is connected with the gas port on upper lid, gas port and cylinder lumen on the upper lid
Connection, the cylinder lumen is connected with the gas port on lower lid, and the flange is provided with the cramp for bending inwards, the cramp
End outward bending forms flange.Cramp snaps onto the end face and wireway of interim respirator upper flange when on the flange of wireway
The end face laminating of upper flange, it is to avoid wireway be directly exposed in air make moist or foreign matter entrance, the bending structure of cramp
So that the flange of interim respirator and wireway realizes that plug-in is loaded and unloaded, it is quick and easy for installation.
Improved, the cramp is connected by screw on flange.
It is improved, connecting rod is provided with the cylinder, the upper end of the connecting rod and upper lid are threadedly coupled, the connecting rod
Lower end and lower cover threaded connection, the cylinder be positioned at lid and lower cover between.It is easy to loading and unloading, it is easy to cleaning.
It is improved, it is respectively equipped with caulking groove, the upper end of the cylinder on the lower surface of the upper lid and the upper surface of lower cover
It is embedded in the caulking groove of lid, the bottom of the cylinder is embedded in the caulking groove of lower cover.Avoid the cylinder from shifting, it is ensured that upper lid and
The sealing connected between cylinder and lower cover and cylinder.
Improved, the flange and upper lid are formed in one structure.
Improved, the upper surface of the flange is provided with wearing layer, the component that the wearing layer passes through following weight
Make and formed：20~30 parts of deionized water, 2~3 parts of hydrochloric acid, 7~10 parts of butyl titanate, 12~17 parts of absolute ethyl alcohol, positive silicic acid
2~3 parts of ethyl ester, 2~3 parts of silane coupler, 2~3 parts of aluminium isopropoxide, 1~2 part of acetylacetone,2,4-pentanedione, 1~2 part of silica gel solvent and stream
1~2 part of flat agent.Flange upper table surface wear is avoided by the setting of wearing layer, and then ensures the laminating degree of flange and wireway, on
State formula formed wearing layer energy strong bond is in flange surface and abrasion resistant effect is good.
Improved, the wearing layer makes to be formed by the component of following weight：25 parts of deionized water, hydrochloric acid 3
Part, 9 parts of butyl titanate, 15 parts of absolute ethyl alcohol, 2 parts of tetraethyl orthosilicate, 2 parts of silane coupler, 2 parts of aluminium isopropoxide, acetylacetone,2,4-pentanedione 1
1 part of part, 1 part of silica gel solvent and levelling agent.
Beneficial effect：
After adopting the above technical scheme, the interim respirator of the invention, exhales when cramp is snapped onto on the flange of wireway temporarily
The end face of haustorium upper flange is fitted with the end face of wireway upper flange, it is to avoid wireway makes moist or different in being directly exposed to air
The entrance of thing, the bending structure of cramp causes that the flange of interim respirator and wireway realizes that plug-in is loaded and unloaded, easy for installation fast
It is prompt.
