Description
Technical field
The utility model belongs to oxygen blast before the auxiliary device of oxygen lance before ironmaking metallurgical furnace, particularly a kind of metallurgical furnace
The Quick Connect Kit of pipe.
Background technology
Blast furnace and Ou Yelu are when burning iron mouth or other slag irons, it is necessary to introduce oxygen into oxygen blown steel pipe front end, then
Steel pipe, burn through iron mouth or slag iron are lighted, since oxygen is dangerous combustion-supporting energy medium, while position is needed replacing in operation
It puts, moves back and forth, this just needs source of the gas reliably to carry out flexible connected with steel oxygen lance, and easily by source of the gas to behaviour
At work, due to burning of the steel oxygen lance when burning operation quickly, burn after use, size is shortened quickly, it is necessary to more
The oxygen blown steel tubulation renewed, replacement finish carry out continued access burning operation that must be quickly, therefore for convenience efficiently by source of the gas
Factory leads to operation area, it is necessary to solve the safely and fast articulation issues of source of the gas and steel oxygen lance, while must also quick-replaceable steel
Oxygen lance processed, this burns the technical barrier that oxygen operates before becoming metallurgical furnace.
Utility model content
The purpose of this utility model is to provide a kind of Quick Connect Kit of oxygen lance before metallurgical furnace, structure is closed
Reason, can solve the safely and fast articulation issues of source of the gas and steel oxygen lance, being capable of quick-replaceable steel oxygen lance.
What the purpose of this utility model was realized in：The Quick Connect Kit of oxygen lance, source of the gas before a kind of metallurgical furnace
The hose of connection is connected with the casing coupling head of the pipe fitting of casing coupling thread connection, and the other end of casing coupling thread connection pipe fitting passes through screw thread
It is connected to both ends and has female coupling tunnel, the first pre-load nut is installed on casing coupling thread connection pipe fitting, in coupling tunnel
Inside cooperation is installed with the first inner tube, the first rubber sleeve, the second inner tube and the second rubber sleeve successively, and the other end of coupling tunnel passes through spiral shell
Line is connected to blowpipe connector, and the second pre-load nut is connected through a screw thread on blowpipe connector, on the outside of the second pre-load nut
Intubation jackscrew in the tube wall screw hole of blowpipe connector is installed, is inserted between the steel oxygen lance in coupling tunnel and first, second inner tube
Gap coordinates, and seals and coordinates with first, second rubber sleeve, is positioned steel oxygen lance by being intubated jackscrew.
The utility model is rational in infrastructure, solves the safely and fast articulation issues of source of the gas and steel oxygen lance, realizes fast
Speed replaces steel oxygen lance.
