Description
Technical field
The utility model relates to common hot blast valve used by a kind of blast furnace ironmaking, especially a kind of common hot blast valve valve
Body.
Background technique
Hot-blast valve is installed on the hot blast manifold between hot-blast stove and hot blast main pipe, is the switching equipment of hot-blast stove air-supply.
It is welded for a long time using mild steel always, water-cooling structure, development had the lining hot-blast valve with refractory lining later, but because of structure
Complexity, it is at high cost, it applies and is subject to certain restrictions on medium and small blast furnace.Common hot blast valve is because structure is simple, and cost is relatively low, medium and small
There are also comparable application spaces in blast-furnace equipment market, but there is the place that has much room for improvement in structure, in recent years hot air valve body and valve
Plate constitutes the position of sealing into hot wind side, is directly constituted with hot air valve plate body into hot wind side side by right tube plate left side
Sealing, but the sealing that right tube plate is constituted due to wall thickness limitation, generally less than 25mm, such right tube plate left side and hot air valve plate
Band is obvious partially narrow, sealing effect is influenced, to influence the service performance of hot-blast valve.The structure at the position is urgently improved.
Utility model content
In view of the above technical problems, the purpose of the utility model is to provide a kind of novel common hot air valve body, overcome
Existing common hot air valve body there are the drawbacks of, hardly increase valve weight and manufacturing cost, but substantially change valve seal
Performance.
The technical solution of the utility model specifically:
A kind of common hot air valve body, including long flange, Zuo Falan, right flange, left plate, right side plate, left tube sheet, right pipe
Plate, interior coaming plate, peripheral board, water inlet pipe, outlet pipe and sewage pipe weld left plate and right side plate, a left side for left plate on long flange
Side is successively welded with left tube sheet and Zuo Falan, and right tube plate and right flange, left plate and right side plate are successively welded in the right side of right side plate
Between weld in coaming plate, be provided with peripheral board on the outside of interior coaming plate, peripheral board is between left flange and right flange, on peripheral board
It is provided with water inlet pipe and outlet pipe, sewage pipe is welded with below interior coaming plate, blowdown pipe end is pierced by peripheral board, the hot-blast valve
The right tube plate left side of valve body is mutually welded with contact ring right side close to inner radius, is leaned at contact ring outer diameter with right side plate left side
It is mutually welded at adjacent pores diameter, is hot air valve plate body between left plate and right side plate, contact ring left side and hot air valve plate body are right
Side constitutes sealing.
The left plate, right side plate, contact ring, left tube sheet, right tube plate, interior coaming plate, peripheral board, left flange and right flange it
Between surround interconnected cooling water cavity.
The wall thickness such as the contact ring and right side plate, contact ring outer diameter are identical with right side plate hole internal diameter.
Compared with the existing technology, the wall thickness such as the contact ring of the utility model and right side plate, contact ring outer diameter and right side plate hole
Internal diameter is identical, and such contact ring and right side plate can save raw material from same steel plate loading and unloading, especially contact ring left side with
Hot air valve plate body is constituted into hot wind side side and is sealed, and sealant band width is than existing structure right tube plate left side as sealing
Face, band obviously broaden, and sealing performance improves, and the valve body economy, sealing effect are good, raw particularly suitable for medium and small blast furnace equipment
It produces and needs.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the diagrammatic cross-section in the direction A-A in Fig. 1.
Specific embodiment
As shown in fig. 1, a kind of common hot air valve body, including long flange 1, Zuo Falan 2, right flange 3, left plate 4, the right side
Side plate 5, left tube sheet 6, right tube plate 7, interior coaming plate 8, peripheral board 9, water inlet pipe 10, outlet pipe 11 and sewage pipe 12 weld on long flange 1
Left plate 4 and right side plate 5 are connect, the left side of left plate 4 is successively welded with left tube sheet 6 and left flange 2, and the right side of right side plate 5 is successively
Right tube plate 7 and right flange 3 are welded, interior coaming plate 8 is welded between left plate 4 and right side plate 5, the outside of interior coaming plate 8 is provided with periphery
Plate 9, peripheral board 9 are provided with water inlet pipe 10 and outlet pipe 11 between left flange 2 and right flange 3 on peripheral board 9, valve body
Lower section is provided with sewage pipe 12, and sewage pipe 12, which is welded on the lower section of interior coaming plate 8 and is pierced by peripheral board 9, to be stretched to outside valve body.
7 left side of right tube plate of hot air valve body is mutually welded with 14 right side of contact ring close to inner radius, outside contact ring 14
It is mutually welded at diameter at right side panel aperture close on 5 left side of right side plate, is hot air valve plate between left plate 4 and right side plate 5
