Abstract
The invention relates to a fuel gas branched pipe, in particular to a fuel gas branched pipe used for a light combustion gas turbine taking gas as fuel. In order to solve the technical problem, the fuel gas branched pipe used for the light combustion gas turbine taking the gas as the fuel which is good in gas tightness and reliable in use safety is provided, and the adopted technical scheme includes that one end of a first pipeline is communicated with a fuel gas total pipe, the other end of the first pipeline is communicated with one end of a second pipeline, the other end of the second pipeline is communicated with one end of a third pipeline, and the other end of the third pipeline is connected with a nozzle. The fuel gas branched pipe used for the light combustion gas turbine taking the gas as the fuel is mainly used for the light combustion gas turbine.
Description
Technical field
The present invention relates to a kind of fuel gas and be in charge of, be specifically related to a kind of fuel gas for the lightweight gas turbine take gas as fuel and be in charge of.
Background technology
Lightweight gas turbine is to derive from take aero-turbine as basis remodeling, development, the fuel of aero-turbine is Aviation Fuel, it was liquid before entering nozzle, because the active force between liquid molecule is larger, certain viscosity is arranged, and fuel gas is in charge of hard tube part and nozzle and fuel gas and is in charge of and is connected the ball that adopts-cone connection between hard tube part and house steward and can guarantees that generally liquid Aviation Fuel does not leak.Yet, when the lightweight gas turbine that comes when remodeling adopts gaseous fuel, gaseous fuel generally all contains one or more in hydrogen, methane, carbon monoxide, inflammable and explosive, poisonous and harmful, and between gas molecule, active force is very little, very easily diffusion, the connection of ball-cone are difficult to guarantee the air-tightness be in charge of.Fuel gas is in case leakage, the very likely accident such as breaking out of fire, blast.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and it is good that technical problem to be solved has been to provide a kind of air-tightness, and the safe and reliable fuel gas that is used for the lightweight gas turbine take gas as fuel is in charge of.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of fuel gas for the lightweight gas turbine take gas as fuel is in charge of, comprise: the first pipeline, the second pipeline and the 3rd pipeline, one end of described the first pipeline is connected with the fuel gas house steward, the other end of the first pipeline is connected with an end of the second pipeline, the other end of described the second pipeline is connected with an end of the 3rd pipeline, and the other end of described the 3rd pipeline is connected with nozzle.
Between described the first pipeline and fuel gas house steward, all be connected by welded flange between the 3rd pipeline and nozzle.
Described the first pipeline and the 3rd pipeline are hard tube.
Described the second pipeline is metal hose.
The beneficial effect that the present invention compared with prior art has is: the fuel gas that the present invention utilizes welded flange and metal hose to form is in charge of, and has greatly improved the air-tightness that fuel gas is in charge of, and guarantees that fuel does not leak, and is safe and reliable.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
In figure: 1 is the first pipeline, and 2 is the second pipeline, and 3 is nozzle, and 4 is welded flange, and 5 is the fuel gas house steward, and 6 is the 3rd pipeline.
The specific embodiment
As shown in Figure 1, a kind of fuel gas for the lightweight gas turbine take gas as fuel is in charge of, comprise: the first pipeline 1, the second pipeline 2 and the 3rd pipeline 6, one end of described the first pipeline 1 is connected with the fuel gas house steward, the other end of the first pipeline 1 is connected with an end of the second pipeline 2, the other end of described the second pipeline 2 is connected with an end of the 3rd pipeline 6, and the other end of described the 3rd pipeline 6 is connected with nozzle 3.
Between described the first pipeline 1 and fuel gas house steward, all be connected by welded flange 4 between the 3rd pipeline 6 and nozzle 3.
Described the first pipeline 1 and the 3rd pipeline 6 are hard tube.
Described the second pipeline 2 is metal hose.
In the present invention, the hard tube material preferably adopts 1Cr18Ni9Ti or 0Cr18Ni9; When the other materials such as employing 30#, 35#, 40#, 45#, 50#, 55#, 60# or 65#, take into full account the physicochemical property of mechanical property, physicochemical property, processing performance and the medium of material.
The above has done detailed description to embodiments of the invention by reference to the accompanying drawings, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also make various variations under the prerequisite that does not break away from aim of the present invention.
