Above-mentioned generating set can be used in pipeline valve station (such as urban gate station).Here, the pressure of gas is carried out in upstream
To be lowered.The present invention is that pressure is being reduced after turbine expansion using pipeline gas.In order to meet the pipe of pipeline transmission
Road atmospheric pressure requires that the pressure of the pipeline gas of Jing turbine expansion blood pressure lowerings needs to maintain predetermined value.Entirely managed according to gas transmission station
Diverse location in road transmission, predetermined value described herein is different.For example, pipeline atmospheric pressure can be depressurized to from 10Mpa
4MPa, 2.5MPa is depressurized to from 4MPa or 1.6MPa is depressurized to from 2.5MPa, and can float within the specific limits.It should be understood that
It is, in some gas transmission stations, other predetermined values or preset range can be maintained through the pipeline atmospheric pressure of pressure regulation.
In some cases, downstream gas consumption is continually changing, therefore can cause the pipeline gas of Jing turbine expansion blood pressure lowerings
Pressure oscillation.In order to maintain its pressure, as shown in figure 1, can 14 upstream of turbine arrange a valve element 50, the valve element 50 to
The flow of the pipeline gas into turbine 14 is adjusted according to the pressure of the pipeline gas in 14 downstream of turbine, the pipeline after pressure regulation is maintained with this
Atmospheric pressure is in predetermined value or preset range.
Valve element 50 is also disposed in shell 12, positioned at inner housing 44 near this one end of pipeline gas entrance 18.Outside valve element 50
Surface defines input channel gas passage 52 with 12 inner surface of shell 28.In order to form uniform pipeline gas passage 52, outside valve element 50
Surface also forms fairing ace, makes valve element 50 be in tapered taper on the direction contrary with airintake direction.In some enforcements
In example, the sectional area of the input channel gas passage 52 is substantially the same with the sectional area of runner 46.In certain embodiments, upstream
The sectional area of pipeline, input channel gas passage 52 and runner 46 is substantially the same.Same cross-sectional area is kept, pipe can be prevented as far as possible

The problem of leakage is addressed.And, only need to during construction by the pipeline gas inlet portion 18 of shell 12 and pipeline gas export department 20 with
Upstream and downstream pipeline connects, therefore the present invention is installed using modularity, and construction is easy.
The movement of valve element 50 not only can adjust the flow of input channel gas, and can also realize the switch work(of pipeline
Energy.Meanwhile, the flow of pipeline gas can be calculated according to the pressure differential and temperature difference and the electricity for sending of turbine upstream and downstream, because
This can be used as effusion meter.Therefore, generating set of the invention realizes pipeline controlled atmosphere pressure, switch, the multi-functional of metering.And
And electromotor can also be radiated using pipeline gas, from another perspective, electromotor can be heated to pipeline gas,
, in some low temp areas, the transmission to pipeline gas is highly advantageous for this.
In sum, the invention provides a kind of puffing turbine power generation unit, its main motion parts is all disposed within
Enclosure, therefore the problem of pipeline gas leakage is addressed.And, at the construction field (site), it is only necessary to which the pipeline gas of shell is entered
Mouth and the outlet of pipeline gas are connected with upstream and downstream pipeline, therefore the present invention is installed using modularity, and construction is easily.The shifting of valve element
The dynamic flow that not only can adjust input channel gas, and the switching function of pipeline can also be realized.Meanwhile, according to turbine upstream
The flow of pipeline gas can be calculated with the pressure differential and temperature difference and the electricity for sending in downstream, therefore can be used as effusion meter.Cause
