Energy and its quality directly affect the total quality of valve.
Hot blast slide valve is the major part that hot-blast valve takes away heat, takes away the energy conservation effect how much heat directly affects valve
Fruit, if Chinese invention patent application CN103421919A also discloses a kind of hot air valve plate, with most traditional hot blast slide valve
Structure is the same, substantially by parts groups such as sealing seam allowance circle, sealing panel, water-stop sheet, cooling water inlet and outlet pipes, refractory insulating layers
At.
But the design feature of above-mentioned traditional hot blast slide valve is that sealing panel uses entirety to forge part, seals seam allowance circle
By inner ring and outer ring welding fabrication, and sealing panel and sealing seam allowance circle are welded to connect, however refractory insulating layer be only arranged at it is close
The surface of cover board, this allows for sealing seam allowance circle leakage outside refractory insulating layer, since entire hot blast slide valve is by high temperature thermal change
Stress, thermal loss is larger under high-temperature baking, welding weld bond fatiguability cracking, therefore welding quality requires height.
Utility model content
In order to overcome the shortcomings of background technique, the utility model provides a kind of Quan Naicai hot blast slide valve, solves existing hot wind
Valve plate is by high temperature thermal change stress weld bond fatiguability cracking, the demanding problem of welding quality.
Technical solution adopted by the utility model: a kind of Quan Naicai hot blast slide valve, including it is primary sealing area plate, second close
Cover board, sealing seam allowance circle, water inlet pipe, outlet pipe, water-stop sheet；The primary sealing area plate is parallel with secondary sealing area plate to be set
It sets, the water-stop sheet is arranged between primary sealing area plate and secondary sealing area plate, and forms the spiral for cooling water circulation
Formula water channel, the water inlet pipe and outlet pipe are respectively communicated with the import and outlet of spiral water channel；The sealing seam allowance circle setting exists
Primary sealing area plate outer ring and sealing cooperation, the section of the sealing seam allowance circle is at U-typed, and one end is two connecting pins, separately
One end forms sealing surface, and described two connecting pins and secondary sealing area plate are welded to connect；The outer surface of the primary sealing area plate,
Outer surface of the outer surface and sealing seam allowance circle of secondary sealing area plate in addition to sealing surface is equipped with one layer of refractory insulating layer.
The refractory insulating layer uses thermal cement.
The outer surface of the primary sealing area plate, secondary sealing area plate, sealing seam allowance circle setting refractory insulating layer, is equipped with
Several muscles and bones being evenly arranged.
The primary sealing area plate, secondary sealing area plate and water-stop sheet weld.
The inner sidewall of the connecting pin and secondary sealing area plate that seal seam allowance circle inner ring welds, outside the secondary sealing area plate
Circle and the inner sidewall of sealing seam allowance circle outer ring weld.
The beneficial effects of the utility model are: changing conventional double-sealing face sealing seam allowance circle is Dan Mi using above scheme
Cover seals seam allowance circle, and other than the sealing surface of sealing seam allowance circle, other positions are integrally equipped with one layer of refractory insulating layer, thus
Transmitting amount of heat is reduced, while each welding position can be covered by refractory insulating layer, to greatly reduce by height
The effect for warming varying stress effectively avoids the problem that welding weld bond fatigue cracking, improves behaviour in service, improve service life.
