Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1-2, manhole device for boiler pressure container, including boilers and pressure vessel body 1;Boilers and pressure vessel
The upper end of body 1 is fixed with manhole pipe 2;The upper end of manhole pipe 2 is fixed with A ring flanges 3;The upper end bolt connection of A ring flanges 3 has B flanges
Disk 4;Seal washer 5 is installed between A ring flanges 3 and B ring flanges 4;Tube coupling body 6 is fixed with the middle of B ring flanges 4;Tube coupling body 6 is pushed up
End is fixed with manhole cover 7;Conical through-hole 8 is provided with the middle of manhole cover 7;Taper pressure block 9 is sliding combined with conical through-hole 8;Pot
Support frame 10 is fixed with furnace pressure force container body 1;Manhole pipe 2 is in the inner side of support frame 10;The top of support frame 10 is rotatably connected to
Inverted " v " pole 11;The one end of inverted " v " pole 11 coordinates with the tip contact of manhole cover 7, the other end and the top of taper pressure block 9
Connection is rotated to coordinate;Uniformly flange plate type short tube 12 and internal thread short tube 13 are communicated with the top sidewall of tube coupling body 6;Manhole pipe 2
For back taper;The bottom of tube coupling body 6 is back taper corresponding with the shape of manhole pipe 2;The bottom outside of tube coupling body 6 and the inner side of manhole pipe 2
It is engaged.
In the utility model, the sealing ring 14 that yielding material makes is fitted with the inwall of manhole pipe 2, when boiler pressure is held
When having pressure in device, it can be brought into close contact using pressure with tube coupling body 6.
Manhole pipe 2 is welded to connect with boilers and pressure vessel body 1, tube coupling body 6 and the bolt connection of manhole pipe 2, and in A methods
Seal washer 5 is installed between blue disk 3 and B ring flanges 4, increases the sealing of connection, prevents inside when bolt loosens
Medium is revealed.
When having pressure inside boilers and pressure vessel, taper pressure block 9 is moved up under the effect of the pressure, due to boiler
Pressure vessel self-temperature is higher, causes the temperature of manhole cover 7 also to raise, when temperature is higher, deformation occurs in manhole cover 7,
Taper pressure block 9 is to be slidably matched with manhole cover 7, therefore a certain amount of displacement occurs in the vertical direction, when taper pressure-bearing
When block 9 is moved up, drive inverted " v " pole 11 to rotate around the axis, moved down with one end of the upper-end contact of manhole cover 7, pressed
Compel manhole cover 7 to move down.Because support frame 10 is fixed on boilers and pressure vessel body 1, it is impossible to mobile, therefore when taper pressure-bearing
When block 9 is moved up, used by coordinating support frame 10 and inverted " v " pole 11, the synthesis decomposition and active force according to power with
The knowledge of reaction force, which can be derived, can produce the power for oppressing manhole cover 7 downwards, and manhole device is in boiler pressure for increase
The stability installed on vessel 1, is more firmly mounted.
Further, since manhole pipe 2 be back taper, add the pressure in boilers and pressure vessel be mainly it is upward, therefore pressure
Power by oppress sealing ring 14 deformed upon to axis direction, then will be fit together with the bottom of tube coupling body 6, by the two it
Between the fastness that is connected with tube coupling body 6 of frictional force increase manhole pipe 2.
, it is necessary to which manhole device is removed when needing to carry out the operation such as internal washing, when removing device, because of boilers and pressure vessel
Inside without pressure, therefore taper pressure block 9 will not produce upward displacement, and inverted " v " pole 11, will to release state
After rotation connection between inverted " v " pole 11 and pressure block 9 is removed, inverted " v " pole 11 just can be from support frame 10
Remove, the devices such as manhole cover 7, tube coupling body 6 then can be just removed successively.Erection sequence is opposite with dismounting order.
Gas collection can be connected on the flange plate type short tube 12 at the top of tube coupling body 6 by way of bolt between ring flange is fixed
Other servicing units such as device, can also be installed by the threaded connection between screw thread short tube.
