Seat, bonnet, connection twisted seat, twisted seat connecting rod, bell jar, installation cat ladder, middle adpting flange, guides stem and valve seat；The centre
Adpting flange lower end is connected by bolt and valve seat；The middle adpting flange upper end is connected with solid with the bonnet
It is fixed；The guiding fixed seat is installed using screw among the bonnet upper end, guides stem is housed among the guiding fixed seat；Institute
Guides stem is stated to pass perpendicularly through the connection twisted seat and put in inside the belljar valve；Between the connection twisted seat and guides stem
Sliding friction coordinates；The connection twisted seat twists with twisted seat connecting rod to be connected；The lower seat of the twisted seat connecting rod is connected with bell jar using bolt
Connect fixation；The steel wire penetrating is oriented to fixed seat；The bell jar possesses the centre bore being slidably matched with guides stem so that institute
Stating bell jar can slide up and down along the guides stem；The middle adpting flange edge suitable for reading is installed by the electric block branch
Frame, electric block is installed on the bracket of electric hoist top；The electric block output end passes through rotating roller and the steel wire rope
It is attached in a manner of rotating and winding；In the bracket of electric hoist side installation and maintenance cat ladder；It is right in the lower end of belljar valve
Side is provided with installation cat ladder；
Further, the connection twisted seat is made with guides stem of stainless steel material；
Further, the bell jar is coordinated with valve seat using circular cone is domatic, and reaches sealing by gravity extruding.
By adopting the above-described technical solution, major diameter belljar valve provided by the utility model, overcomes traditional belljar valve
Airtight performance is poor, and the defects of easily being deformed in hot environment, the utility model has that simple in construction, heat resistance is good, no
The advantages of yielding and good seal performance, equipment fault can be effectively reduced, reduce potential safety hazard, relatively reliable practical skill
Art, there is wide development space.

Embodiment
A kind of major diameter belljar valve as depicted in figs. 1 and 2, including：Electric block 1, bracket of electric hoist 2, maintenance are climbed
Ladder 3, steel wire rope 4, it is oriented to fixed seat 5, bonnet 6, connection twisted seat 7, twisted seat connecting rod 8, bell jar 9, installation cat ladder 10, middle connection method
Orchid 11, guides stem 12 and valve seat 13；The lower end of middle adpting flange 11 is connected by bolt and valve seat 13；In described
Between the upper end of adpting flange 11 be joined with bolts with the bonnet 6；Led among the upper end of bonnet 6 using described in screw installation
To fixed seat 5, guides stem 12 is housed among the guiding fixed seat 5；The guides stem 12 passes perpendicularly through the connection twisted seat 7
And put in inside the belljar valve；Sliding friction coordinates between the connection twisted seat 7 and guides stem 12；The connection twisted seat 7
Twist and connect with twisted seat connecting rod 8；The lower seat of the twisted seat connecting rod 8 is fixed with bolts with bell jar 9；The steel wire rope 4 passes through
It is oriented to fixed seat 5；The bell jar 9 possesses the centre bore being slidably matched with guides stem 12 so that the bell jar 9 can be along described
Guides stem 12 slides up and down；The bracket of electric hoist 2 is installed in 11 edge suitable for reading of middle adpting flange, electronic at this
The top of cucurbit support 2 is installed by electric block 1；The output end of electric block 1 is twined by rotating roller and the steel wire rope 4 with rotating
Around mode be attached；In the side installation and maintenance cat ladder 3 of bracket of electric hoist 2；Set on the right side of the lower end of belljar valve
There is installation cat ladder 10；Further, the connection twisted seat 7 is made with guides stem 12 of stainless steel material；Further,
The bell jar 9 is coordinated with valve seat 13 using circular cone is domatic, and reaches sealing by gravity extruding.
The model CD2-6A types of electric block 1 described in the utility model, belong to valve seat 13 described in existing former and height
After the adpting flange that furnace roof end is set is bolted fixation, edge slot builds sealing by laying bricks or stones with heat resistance concrete；The centre
Build fire resisting silicate heat-insulation layer inside adpting flange 11 by laying bricks or stones, outside builds silicate heat-insulation layer by laying bricks or stones.The bell jar 9 is using thickening cast steel
Integral design, high temperature resistant are indeformable.
As depicted in figs. 1 and 2, the course of work of belljar valve described in the utility model is as follows：Electric block 1 screws steel wire rope
4, and then lift bell jar 9 and be lifted up along guides stem 12 to top, belljar valve is opened, coal gas is by blast furnace through middle connection method
