Abstract
The utility model discloses a novel ball valve device and belongs to the technical field of metallurgical equipment. The novel ball valve device is divided into a front section and a back section and comprises a flange, a ball valve shell body, a sealing steel ball, a ball body slide, a cutting sleeve, a gun clip, a locking nut, a sealing gasket, sealing filler, a jackscrew and a coal injection gun barrel. The ball valve shell body of the front section is installed on a blast furnace blowing-in belly pipe and is connected through the flange, and the gun clip of the back section is installed on the coal injection gun. The gun clip is rotated clockwise by certain angle in gun-inserting operation, and is tightened with the cutting sleeve to form an entirety. The sealing gasket is arranged between the gun clip and the cutting sleeve. When the coal injection gun is extracted, the sealing steel ball falls automatically down along the ball body slipway to undertake the function of sealing. The angle and the height of the coal injection gun can be adjusted simply by unscrewing the jackscrew. The novel ball valve device has the advantages of being long in service life, good in sealing performance, strong in interchangeability, and capable of reducing spare part expense greatly. The novel ball valve device can achieve normal production of the blast furnace and reduce damping-down rate.
Description
One, affiliated technical field:
Belong to technical field of metallurgical equipment.
Two, background technology:
Certain 6# of iron and steel enterprise pulverized coal injection into blast furna powder system adopts the injection technology of Dutch Danieli Off Mecc.This injection system is in the pulverized coal injection in blast furnace process, there is the defective that can not plug or change or regulate spray gun with pressure, 15 air ports have just been stung bad in that winding-up test is of that month, although it is bad that the air port that has is not stung, but also stung out groove, just do not ground the mouth that leaks out, seriously contained blast furnace production, the blast furnace staying rate increases because changing the air port, and blast furnace can not strengthening smelting because of the coal injection minimizing.
Three, summary of the invention:
The purpose of this utility model provides the ball valve device of the plug with pressure of a kind of energy, adjusting and replacing coal spouting gun.
By the research to Dutch Danieli Off Mecc injection system and slotting gun apparatus, utilize Dutch Danieli Off Mecc to insert the characteristics of gun apparatus good airproof performance, defective for the slotting gun apparatus of original use makes up for each other's deficiencies and learn from each other, and works out a kind of novel coal spouting gun and plugs in the rifle ball-cock device.
The utility model comprises forward and backward two parts, comprises the component such as flange, ball valve shell, sealed steel ball, spheroid slideway, cutting ferrule, rifle clamp, set nut, gasket, lock packing, jackscrew, coal powder injection gun barrel.Front portion is ball valve shell, is contained on the blast furnace air-supply belly pipe, connects with flange, and latter part of rifle clamp is contained on the coal spouting gun.
When plugging in the rifle operation, the rifle clamp rotates to an angle in the direction of the clock, tightens with the cutting ferrule of ball-cock device to become one, and gasket is arranged between them, prevents that high-temperature gas from leaking outside; Under the effect of blast, sealed steel ball deposits in the ball valve shell along the spheroid slideway; When coal spouting gun was extracted ball valve shell, blast was removed, and sealed steel ball falls automatically along the spheroid slideway, seals, and prevented the ejection of blast furnace high temperature and high pressure gas.Jackscrew contacts fixing on the rifle clamp with the coal spouting gun tube outer surface.In the set nut and between the rifle clamp lock packing is arranged, they twist into one.When blast furnace is produced, for regulating coal spouting gun angle and length, jackscrew is unscrewed, is rotated coal spouting gun or regulate coal spouting gun length, regulate suitable after, tighten jackscrew, coal spouting gun is fixed.If coal spouting gun has air leakage phenomena, tighten again set nut.
When the ball valve device is normally produced at blast furnace, can with pressurely plug, regulate coal spouting gun, again can the replace with pressure coal spouting gun.And be hundred times that legacy system is inserted gun apparatus work-ing life its work-ing life.Greatly reduce the spare part expense.Satisfy the normal production of blast furnace, reduced the delay ratio of blast furnace.
Four, description of drawings:
Fig. 1 is ball valve device assembly construction synoptic diagram.
1-flange pup joint, 2-ball valve shell, 3 sealed steel balls, 4-spheroid slideway, 5-cutting ferrule, 6-rifle clamp, 7-set nut, 8-gasket, 9-lock packing, 10-jackscrew, 11-coal powder injection gun barrel among the figure.
Five, embodiment:
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Embodiment 1
The utility model divides two portions, and the ball valve shell 2 of front portion is fixedly mounted on the blast furnace air-supply belly pipe, connects with flange 1, and latter part of rifle clamp 6 is contained on the coal spouting gun 11.When plugging in the rifle operation, after coal powder injection gun barrel 11 inserted ball valve shells 2, rifle clamp 6 rotated to an angle in the direction of the clock, was abutted against with the cutting ferrule 5 of ball-cock device that to touch the inclined-plane fastening, and gasket 8 is arranged between them, prevented that high-temperature gas from leaking outside; Under the effect of blast, sealed steel ball 3 deposits in the ball valve shell 2 along spheroid slideway 4; When coal spouting gun 11 was extracted ball valve shell 2, blast was removed, and sealed steel ball 3 falls along 4 deadweights of spheroid slideway, forms the stiff dough sealing under the inside and outside differential pressure effect, prevents that blast-furnace hot-air from blowing out.Jackscrew 10 contacts fixing on rifle clamp 6 with coal powder injection gun barrel 11 outside surfaces.In the set nut 10 and between the rifle clamp 6 lock packing 9 is arranged, they twist into one.When blast furnace is produced, for regulating angle and the length of coal spouting gun 11, jackscrew 10 is unscrewed, is rotated coal spouting gun 11 or regulate coal spouting gun 11 length, regulates suitable after, tighten jackscrew 10, coal spouting gun 11 is fixed.If coal spouting gun 11 has air leakage phenomena, tighten again set nut 7.
When the ball valve device is normally produced at blast furnace, can change and can regulate coal spouting gun 11.And its work-ing life be hundred times that legacy system is inserted gun apparatus work-ing life, greatly reduce the spare part expense.Satisfy the normal production of blast furnace, reduced the delay ratio of blast furnace.
