Certainly existing manhole door returns the problem of dress technology: 1, influencing unit on-load.2, after high-pressure heater is out of service, water supply
Temperature is low, and coal consumption increases.3, service personnel's labor intensity increases, and the cost of overhaul increases.
In order to realize above-mentioned technical problem, the utility model adopts the following technical solution:
A kind of High Pressure Heater in Thermal Power Station manhole door that can quickly return dress, including it is high-pressure heater shell, built-in
Formula manhole door and clamp device；High-pressure heater shell is equipped with manhole；Built-in manhole door section is in convex shape, including big end
And small end；The diameter of big end is greater than the diameter of manhole；Big end is located at high-pressure heater enclosure interior；One end of big end adds with high pressure
Hot device inner walls are hinged；The diameter of small end and the diameter matches of manhole；The bottom of small end is fixed with guiding device；Fastening dress
It sets, for fixing high-pressure heater shell and built-in manhole door.
Further, guiding device includes welding to lead arc to plate on the outside of pre- small end bottom.
Further, arc is led to being welded with several ribs between plate and small end.
Further, it leads arc and is equipped with chamfering to board bottom portion.
Further, lead arc to the length of plate be 150mm, width 3mm.
Further, the outside of small end is equipped with push-pull ring.
Further, it when built-in manhole door returns dress completion status, is also set between big end and high-pressure heater inner walls
There is metallic gasket.
Further, clamp device includes the stud being fixed on small end, fixed plate and nut；Built-in manhole door returns dress
When completion status, stud passes through fixed plate and is tightened by nut.
Further, the outer wall that high-pressure heater shell is located at manhole is equipped with annular convex platform；Fixed board ends ride over convex
On platform.
Compared with the existing technology, the utility model has the following beneficial effects:
1. high-pressure heater returns dress manhole door after having overhauled, the primary success of dress is returned using guide plate, avoids and does over again, contract
The short repair time, it ensure that repair quality.2. reducing personnel labor intensity, ensure that repair quality, saved maintenance at
This.By calculating, fill for every time before a manhole is relatively transformed compared to nearly 10000 yuan of the cost of overhaul of saving.
