Description
Technical field
This utility model belongs to blast-furnace tuyere leakage testing device technical field, is related to a kind of blast-furnace tuyere leak test rifle.
Background technology
When the blower parts such as tuyere big sleeve, middle set, little set, blowpipe are damaged or adjust air port size, length, we just need
Air port blower part is dismounted, in order to ensure after multiple wind not leakage gas, we will install laggard sector-style in air port blower part
Oral examination is leaked.
However, traditional air port leak test instrument is air port peep-hole to be inserted with oxygen lance, send into compressed air toward in blowpipe,
Then the wooden stick that front end is tied with plastic tape is stretched into little set and blowpipe contact surface again, sees whether plastic tape waves, if plastic tape
Wave, air port is leaked out.There are several obvious shortcomings in this traditional air port leak test instrument：First, the number for needing is more, leak test
When need people control valve switch at the source of the gas, a people to hold oxygen lance and send into compressed air toward in blowpipe, a people takes
Wooden stick and see whether plastic tape waves.2nd, can not comprehensive detection leak source, front end be tied with the wooden stick of plastic tape only detect several
Point, it is impossible to cover leak source comprehensively.3rd, long the time required to leak test, as air port region water pipe is more, narrow space, wooden stick are repeatedly stretched
Enter the long period to be consumed.4th, DeGrain, because oxygen lance bore is big, and only in one direction, modeling less when leaking out
When material strip slightly waves, it is difficult to discover.
Utility model content
In order to overcome the disadvantages mentioned above of prior art, this utility model to provide a kind of blast-furnace tuyere leak test rifle, it has energy
Enough comprehensive detection leak sources, one is just operable, time saving and energy saving, the features such as effect is obvious.
This utility model solves the technical scheme adopted by its technical problem：A kind of blast-furnace tuyere leak test rifle, by sending ash
Gun barrel, Sheng ash bucket, air inlet pipe composition, send grey barrel muzzle to shut, let out grey hole sending grey gun barrel front end to be drilled with 6 groups every 10cm,
This send grey gun tube rear end seamless welding away from containing on ash bucket at 1cm, is sending grey gun tube rear end to be socketed with gum cover, is containing ash bucket bottom
Plate center weld has stud, the lid that inner surface setting has sealing gasket then to fix on the cover board through stud, arrange on lid
There are Cornu Caprae seu Oviss nut, twisting Cornu Caprae seu Oviss nut cover tightly lid, contain hopper bottom and air inlet pipe front end seamless welding, air inlet pipe rear end
There is a rear tab to connect with compressed air hose and use spring hoop banding.
The stud and centre-drilling hole external diameter are suitable.
Control valve is housed in the middle of the air inlet pipe.
The beneficial effects of the utility model are：Leak test rifle has simple structure, with low cost, it is easy to safeguard, can be entirely square
Position detection leak source, one is just operable, the features such as time saving and energy saving.
Description of the drawings
Fig. 1 is this utility model vertical section structural map.
Fig. 2 is top view of the present utility model.
In figure：1- lets out grey hole, and 2- gum covers, 3- Cornu Caprae seu Oviss nuts, 4- studs, 5- lids, 6- contain ash bucket, 7- control valves, 8-
Rear tab, 9- send grey gun barrel, 10- air inlet pipe.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is further illustrated.
Referring to Fig. 1 and Fig. 2, a kind of blast-furnace tuyere leak test rifle, constituted by sending grey gun barrel 9, containing ash bucket 6, air inlet pipe 10, send ash
9 muzzle of gun barrel is shut, and lets out grey hole 1 sending 9 front end of grey gun barrel to be drilled with 6 groups every 10cm, and this send 9 rear end seamless welding of grey gun barrel to exist
Away from containing on ash bucket 6 at 1cm, sending 9 rear end of grey gun barrel to be socketed with gum cover 2, having stud 46 base plate center weld of ash bucket is contained, interior
Surface is provided with the lid 5 of sealing gasket and then fixes on the cover board through stud 4, is provided with Cornu Caprae seu Oviss nut 3 on lid 5, twisting
Cornu Caprae seu Oviss nut 3 can cover tightly lid 5, contain 6 bottom of ash bucket and 10 front end seamless welding of air inlet pipe, and 10 rear end of air inlet pipe has one
Rear tab 8 is connected with compressed air hose and uses spring hoop banding.
The stud 4 and centre-drilling hole external diameter are suitable.
Control valve 7 is housed in the middle of the air inlet pipe 10.
This utility model has simple structure, with low cost, it is easy to safeguard, can comprehensive detection leak source, one just may be used
Operation, the features such as time saving and energy saving.
