In the perforate of upper body, connection sealing is realized by sealing structure.
Preferably, described collocation structure includes installing cushion block, flexible member, installs supporting plate and install guide rod.
Preferably, flexible member is compression spring, expansion bellow or butterfly spring.
Preferably, sealing structure, including connecting short section and encapsulant, connecting short section is by bolt, pad and container
Upper body is fastenedly connected sealing.
Preferably, seal form can be labyrinth seal, packing seal, O-ring sealing in one kind or therein group
Conjunction form.
Said vesse is set to two or more, facilitates installation and maintenance.Flange passes through O-ring or pad and fastening
Part is connected.
Wherein, heated element manufacture and installation process in, must ensure linearity, it is ensured that uniformly produced upwards during expanded by heating
Displacement.
Due to the presence of hot environment, device interior sets cooling component, and internal jacket cylinder, discharging/feed pipe are set
Cooling component, cooling component is cooled down from chuck, bushing type；
The quantity of flexible member should be set to 4 multiple, and be evenly arranged along center span centre, so that proof stress is uniform.
When connecting short section is connected with upper vessel portion shell flange, flange gasket or O-ring sealing are can select, it is tight by bolt
Firmware is tightened.
The beneficial effects of the utility model are：The utility model collocation structure main element includes spring, supporting plate, sealing
The elements such as part, will not need to set expansion joint in container, and solution is difficult to the difficulties such as internal installation connection, new using this practicality
Type, it is possible to increase installation effectiveness and security, reduces equipment investment and manufacturing cost.

Specific embodiment
Specific embodiment of the present utility model is described in detail below：
Reference picture 1, Fig. 2 and Fig. 3, a kind of thermal expansion absorbing structure, including lower vessel portion housing 1 and internal jacket cylinder 6,
Lower vessel portion housing 1 is provided with supporting plate 2, and heated element 3 is placed in supporting plate 2, heated element 3 and internal jacket cylinder 6 it
Between place gasket seal 4, the mounting seat of collocation structure 5 is set in the mounting seat of internal jacket cylinder 6, collocation structure 5 is arranged on
On jacket cylinder 6, charging/discharge nozzle 8 is inserted in the perforate of upper vessel portion housing 7, and connection sealing is realized by sealing structure 9.
Described collocation structure 5 includes installing cushion block 5-1, flexible member 5-2, installs supporting plate 5-3 and install guide rod 5-4.
Flexible member 5-2 is compression spring, expansion bellow or butterfly spring.
Sealing structure, including connecting short section 9-1 and encapsulant 9-2,9-3；Connecting short section passes through bolt, pad and container
Upper body 7 is fastenedly connected sealing.Seal form can be labyrinth seal, packing seal, O-ring sealing etc. dynamic sealing form or
Combining form therein.
Container lower house 1 is fixed on steel construction or ground, by heated element placement and inner barrel supporting plate 2.Place
Gasket seal 4 is hung with row and for internal jacket cylinder 6 to be placed on heated element top in the upper surface of heated element 3, is slowly drop down to
Fitted with heated element upper surface；Collocation structure 5 is internally installed on the spring mounting seat of jacket cylinder 6.Hung container with row
Upper body 7 is hung to directly over container lower house 1, it is ensured that charging/discharge nozzle 8 is slow to be led to from the perforate flange of upper shell
Cross, slowly carried out during decline；Container upper and lower casing flange is connected with fastening.Now feed/discharge tube chamber domestic demand
It is isolated with the cavity of container casing, it is necessary to seal, setting sealing structure 9 installs connecting short section and seal 9-2,9-3；
In actual production process, container internal heat generation element 3 is heated, and bottom is supported due to fixed, can be produced upwards axially
Displacement L1；The displacement of expansion upwards causes internal jacket cylinder 6 also with moving upwardly together；Now depositing due to supporting plate 5-3
Flexible member is compressed.After certain temperature T is reached, flexible member is L2 by decrement, and spring now is due to being pressed
Contracting produces pressure F；Therefore gasket seal 4 between heated element 3 and internal jacket cylinder 6 is compressed, and power F acts on pad
On, so as to reach the stress that sealing needs, realize sealing herein.Because internal jacket cylinder 6 is same with charging/discharge nozzle 8
Shi Shangyi, charging/discharge nozzle realizes axial displacement inside connecting short section 9-1.In addition, charging/discharge nozzle 8 and connecting short section 9-
Dynamic sealing is realized by seal 9-2,9-3 between 1.So as to realize that the swell increment caused due to high-temperature expansion is compensated.
