Lose, affect boiler efficiency.
Content of the invention
For solving the above problems, the utility model provides a kind of sealing structure being applied to economizer ventilation beam, welding
Difficulty is low, good sealing effect.
A kind of sealing structure being applied to economizer ventilation beam described in the utility model, including economizer ventilation beam, steel
Set a roof beam in place, economizer backplate and sealing device, described economizer backplate is installed on described truss-steel beam, and described economizer ventilation beam is swollen
Swollen end is located on described truss-steel beam through described economizer backplate, and described sealing device is set in described economizer ventilation beam and expands
End is simultaneously welded with described economizer backplate and described truss-steel beam respectively.
Improve further, described sealing device includes bend, pars contractilis and stop nut, described bend head end and institute
State the welding of economizer backplate, described bend tail end is connected with described pars contractilis head end, is provided with limited block above described pars contractilis,
Described stop nut is connected through described limited block with described bend.
Described sealing device is set in the expanding end of ventilation beam, and sealing device is welded with economizer backplate and truss-steel beam respectively
Connect, welding difficulty is low, be difficult sealing-off, limited block is preferably located at pars contractilis end, stop nut is tightened on limited block or unclamped,
Adjust the amount of unclamping of pars contractilis, to adapt to the expansion or shrinkage of ventilation beam expanding end.
Improve further, described pars contractilis is ripple struction, described pars contractilis is provided with some reinforcing rings, described reinforcing ring
It is located at the sunk part of described ripple struction, so that pars contractilis is more firmly hardly damaged.
Improve further, the bending radius of described bend is 50mm, and welding effect is optimal.
Improve further, described sealing device is made up of the steel plate punched of 2mm-3mm of thickness.
