Technical field
The utility model relates to a kind of burning oxygen to drain rifle, belong to iron and steel smelting technology field.
Background technique
In modern steel integrated complex, oxygen is important industrial gasses, and dosage is very big, and oxygen steelmaking is exactly a kind of oxygen
Gas method for making steel reacts oxygen and carbon and generates carbon dioxide and remove carbon monoxide for smelting iron by supplying oxygen to ironmaking processes, will
Iron is restored from compound；It is all by artificial direct without suitable operational instrument at present when burning oxygen or oxygen is burnt in drainage
Oxygen pipe is inserted into oxygen air induction hose and burns oxygen, purging area is small, and oxygen pressure is big, is manually not easy to grasp size, need centainly
Skill, the spray of molten steel splash is irregular, easily scald staff；Oxygen is burnt in traditional drainage, and two people is needed to operate, and a people, which opens, to pour, and one
People burns oxygen, and because that can not accomplish simultaneously operating, throughput is unable to control so as to cause tempering hidden danger；For this purpose, needing a kind of structure letter
Single, easy to operate, highly effective and safe device solves the above problems.
Summary of the invention
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of structures to be simple and convenient to operate, highly effective and safe
It burns oxygen and drains rifle.
Purpose of the utility model is realized as follows:
A kind of burning oxygen drainage rifle includes stainless steel ball valve, and one end valve port of the stainless steel ball valve welds aerobic pipe-in-pipe,
The oxygen pipe-in-pipe is equipped with through-hole, is provided with locking device right above through-hole, and oxygen pipe is plugged in oxygen pipe-in-pipe, turn locking
Device is fixed locked by oxygen pipe, and the outer diameter of above-mentioned oxygen pipe is less than the internal diameter of oxygen pipe-in-pipe；Another end valve of the stainless steel ball valve
Mouth is welded with hose sleeve, and the tail end of above-mentioned hose sleeve is connected with oxygen air induction hose；
A kind of burning oxygen of the utility model drains rifle, and the locking device includes to be vertically provided at right above oxygen pipe sleeve pipe through-hole
Boss, the center of the boss is equipped with through-hole and is connected with the through-hole of oxygen pipe-in-pipe, is provided in the through-hole of the boss
Screw thread, matched lock-screw are screwed on boss；
A kind of burning oxygen of the utility model drains rifle, and the inner wall of the oxygen pipe-in-pipe is provided with sealant, and sealant is flexibility
Material；
A kind of burning oxygen of the utility model drains rifle, and the end outer wall of the hose sleeve is equipped with multiple evenly arranged rings
Shape flange collar；
Compared with prior art, the utility model has the beneficial effects that
The utility model connect oxygen pipe with oxygen pipe-in-pipe by the way that drainage rifle is arranged between oxygen pipe and oxygen air induction hose
And be locked by locking device, it is connect into oxygen hose with hose sleeve and passes through the increase increase of casing tail portion annular bead and rubbed
Power is wiped, prevents tempering phenomenon occur due to air-flow is excessive to be caused and disengage into oxygen hose and hose sleeve, while improving air-tightness；It is logical
Cross stainless steel ball valve control oxygen flow, can one man operation, structure is simple and convenient to operate, highly effective and safe.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram for burning oxygen and draining rifle of the utility model.
Fig. 2 is a kind of oxygen pipe-in-pipe structural schematic diagram for burning oxygen and draining rifle of the utility model.
Fig. 3 is a kind of hose sleeve structural schematic diagram for burning oxygen and draining rifle of the utility model.
Wherein:
Stainless steel ball valve 1, oxygen pipe-in-pipe 2, sealant 2.1, hose sleeve 3, annular bead 3.1, locking device 4, boss
4.1, lock-screw 4.2, oxygen pipe 5.
Specific embodiment
Referring to Fig. 1~3, the utility model relates to a kind of burning oxygen drain rifle, include stainless steel ball valve 1, the stainless steel
One end valve port of ball valve 1 welds aerobic pipe-in-pipe 2, and the oxygen pipe-in-pipe 2 is equipped with through-hole, and locking dress is provided with right above through-hole
Set 4, being plugged to oxygen pipe 5 in oxygen pipe-in-pipe 2 when use, turn locking device 4 is fixed locked by oxygen pipe 5, above-mentioned oxygen pipe 5
Outer diameter is less than the internal diameter of oxygen pipe-in-pipe 2；The other end valve port of the stainless steel ball valve 1 is welded with hose sleeve 3, above-mentioned Hose Jacket
The tail end of pipe 3 is connected with oxygen air induction hose；
Further, the locking device 4 includes the boss 4.1 for being vertically provided at 2 outer wall of oxygen pipe-in-pipe, the boss
4.1 center is equipped with through-hole and is connected with oxygen pipe-in-pipe 2, is provided with screw thread in the through-hole of the boss 4.1, matched
Lock-screw 4.2 be screwed on boss 4.1, when oxygen pipe 5 is plugged in oxygen pipe-in-pipe 2, turn lock-screw 4.2 is by oxygen pipe
5 are locked；
Preferably, the inner wall of the oxygen pipe-in-pipe 2 is provided with sealant, and sealant is flexible material, ensure that oxygen pipe sleeve
Air-tightness between pipe 2 and oxygen pipe 5；
Further, the end outer wall of the hose sleeve 3 is equipped with multiple evenly arranged annular beads 3.1, oxygen
Air induction hose increases frictional force after being socketed on hose sleeve 3, prevents from leading to oxygen hose and hose sleeve 5.3 because air-flow is excessive
It disengages and tempering phenomenon occurs, while improving air-tightness；
Working principle:
When needing to burn oxygen, oxygen pipe is plugged in oxygen pipe-in-pipe, and with locking device is fixed oxygen pipe locked；Connect oxygen
Afterwards, oxygen flow is controlled by stainless steel ball valve, starts to burn oxygen, one can be operated, and tolerance is adjustable, securely and reliably.
In addition: it should be noted that above-mentioned specific embodiment is only a prioritization scheme of this patent, the skill of this field
Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent..
