Abstract
The utility model relates to a connection structure between an exhaust hood and a condenser. The connection structure can be easily and rapidly assembled. The connection structure comprises a reverse flange located between the exhaust hood and the condenser. The reverse flange comprises a first flange, a transition ring and a second flange. The first flange is connected with the second flange through the transition ring. The exhaust hood is connected with the first flange. The condenser is connected with the second flange. The utility model further relates to an industrial steam turbine comprising the connection structure.
Description
Technical field
The utility model relates to the linkage structure between exhaust casing and condenser, especially the exhaust casing of industrial steam turbine and the linkage structure between condenser.In addition, the utility model also relates to a kind of industrial steam turbine that comprises aforementioned linkage structure.
Background technique
Steam turbine can be used for for the equipment such as generator, compressor, pump provide power, and can be applicable to power plant, chemical plant, sugar refinery, textile mills, steel mill, paper mill or mine etc.Related system generally comprises: steam generator, and it becomes steam by heating (for example,, by coal, rock gas or fuel oil) by water; Steam turbine, it becomes kinetic energy to drive various device the transformation of energy comprising in steam.The stator blade of presence bit on cylinder body and be positioned at epitrochanterian moving vane in steam turbine.When steam turbine operation, some levels that the high pressure steam of expansion becomes with moving vane alternative arrangement through stator blade rotate rotor.Pressure in steam turbine is along with the stage of steam by succession and constantly reduce.Different applications also requires steam turbine to have various steam flow configurations, for example condensation or non-condensing steam discharge, straight-through or controlled drawing gas or controlled admission.
The in the situation that of condensation steam discharge, steam is discharged from after by turbine blade, and is directed into condenser to convert water to, finally can turn back to steam generator.In the situation that drawing gas, steam is drawn out of from steam turbine, and is used to need other occasions (for example, preheating water boiler etc.) of the steam of specified pressure and temperature.The position of drawing gas can be positioned at qualified any position on steam path, and the steam extracting can be controlled by valve.
When using condenser, condenser is by being connected with exhaust casing such as modes such as bolts.This requires the location between condenser and exhaust casing very accurate, therefore positioning action is very complicated, need to take a long time.
Model utility content
The purpose of this utility model be to provide between a kind of exhaust casing and condenser can be simply and the linkage structure of assembling rapidly.This linkage structure comprises an inverse flange between exhaust casing and condenser.Described inverse flange comprises first flange, a transition ring and second flange, and wherein said the first flange is connected by described transition ring with described the second flange.Described exhaust casing is connected with described the first flange, and described condenser is connected with described the second flange.
According to an aspect of the present utility model, described the first flange, described transition ring and described the second flange are as a whole.
According on the other hand of the present utility model, described exhaust casing is connected with described the first flange by bolt, screw, bar or double-screw bolt, and described condenser is connected with described the second flange by welding.
The purpose of this utility model is to provide a kind of industrial steam turbine that comprises above-mentioned linkage structure.Industrial steam turbine of the present utility model allows the larger deviation that is connected with between exhaust casing and condenser, thereby save, is installed the required time of steam turbine, and can supports condenser with simple supporting element.

Embodiment
For technical characteristics of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing embodiment of the present utility model is described.Identical in the drawings label represents identical or structural similarity but the identical parts of function, and wherein has the parts of same structure or function, has only schematically described one of them, or has only marked one of them.For making drawing succinct, in figure, only schematically shown the part relevant to the utility model, they do not represent that it is as the practical structures of product." connection ", " fixing " represent directly " connection ", " fixing " herein, or via " connection ", " fixing " of the third party.
Fig. 1 has schematically shown the industrial steam turbine 1 having according to the linkage structure between exhaust casing 12 of the present utility model and condenser (not shown), and wherein exhaust casing 12 is connected to steam turbine cylinder 11.As shown in Figure 3, exhaust casing flange 121 is parts of exhaust casing 12, and is positioned on one end of exhaust casing 12.As shown in Figure 2 and Figure 3, inverse flange 15 comprises the first flange 151, transition ring 152 and the second flange 153, and wherein the first flange 151 is connected by transition ring 152 with the second flange 153.Exhaust casing 12 is connected with the first flange 151, and condenser is connected with the second flange 153.As shown in Figure 2, the first flange 151, transition ring 152 and the second flange 153 are fixed to one another by welding, but also can form by the mode of for example casting an integral body.As shown in Figure 3, the exhaust casing flange 121 of exhaust casing 12 is connected with the first flange 151 by bolt, and condenser is connected with the second flange 153 by welding.It will be apparent to one skilled in the art that bolt connection can replace with screw, bar or double-screw bolt.Because condenser is welded on the second flange 153, and wide for welding the surface of the soldered condenser of the surface ratio of condenser on the second flange 153, therefore allow larger deviation when welding condenser, thereby linkage structure of the present utility model allows to carry out rapidly and assembling easily, and can support condenser with simple supporting element between exhaust casing and condenser.
Be to be understood that, although this specification is described according to each mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can, through appropriately combined, form other mode of executions that it will be appreciated by those skilled in the art that.
In this article, " schematically " expression " is served as example, example or explanation ", any diagram, the mode of execution that are described in this article " schematically " should be interpreted as a kind of preferred or have more the technological scheme of advantage.
The foregoing is only the schematic embodiment of the utility model, not in order to limit scope of the present utility model.Any those skilled in the art, is not departing from equivalent variations, modification and the combination of doing under the prerequisite of design of the present utility model and principle, all should belong to the scope of the utility model protection.
