Purpose of the utility model is to solve the above problems, devise a kind of new gas turbine.
Realize that above-mentioned purpose the technical solution of the utility model is a kind of new gas turbine, including table body, the table body
Inside be equipped with both ends open channel, the both ends of the table body are respectively inlet end and outlet side, the inlet end of the table body
Equipped with preceding conducting element, the outlet side of the table body is equipped with rear conducting element, and the inside of the table body is equipped with middle guiding element, the middle guiding element
Including the support of bearing, bearing, impeller, axis, wherein
The support of bearing is arranged in the middle part of the inner cavity of table body, inserts axis on the support of bearing, the support of bearing with
Junction between axis is equipped with bearing, and one end of the axis is equipped with impeller；
The middle guiding element terminates in the impeller, and the one end far from preceding conducting element of the impeller set loaded on the axis is described
Region between the inlet end and impeller of table body forms preceding flow-guiding channel, for increasing the length of flow-guiding channel.
Preferably, the inner passage of the table body and the axis of the middle guiding element are concentric.
Preferably, the table body extends outward to form bulge loop on the side surface of left and right port；
The bulge loop, for holding, convenient for carrying out Butt Assembling with gas delivery channels.
Preferably, the region between the inlet end and impeller of the table body forms the inside that preceding flow-guiding channel is greater than table body
The 2/3 of channel.
Beneficial effect
A kind of new gas turbine made using the technical solution of the utility model, before middle guide structure is placed on, leaf
Take turns posterior assembly method, inverted structure be led by be partially installed on before on water conservancy diversion, such mode make in lead part at
In order to which a part of preceding water conservancy diversion extends, so that the length of preceding water conservancy diversion up to 2/3rds, enhances the diversion effect of preceding water conservancy diversion, from
And requirement is also reduced to installation environment, improve application range；
The rectification length rectified before gas turbine meter effectively is increased, rectification effect is improved, improves rectification
Stability, once added rectification efficiency, improved the scope of application of gas turbine meter.

Specific embodiment
The prior art, as shown in Figure 1:
The basic structure that traditional gas-turbine uses is before import i.e. left-hand is to so impeller is in preceding, axis for, left-hand
The assembling structure that is positive after is held, this structure is the widely used structure of gas-turbine in industry.For gas-turbine mainly by table body
101, preceding conducting element 103, impeller 107, the middle guide structure being made of axis 102, bearing 107, the support of bearing 105, rear conducting element 104
Deng composition, preceding 103 a big chunk of conducting element affects the precision of gas-turbine, and the water conservancy diversion length of preceding conducting element 103 one
Divide and affects whether the rotation of impeller 107 is uniform, and a part affects the environmental requirement that gas turbine meter is mounted on pipeline.
Preceding flow-guiding channel is longer, better for the rectification effect of fluid, and under traditional structure, because of the dress of impeller 107 and middle guide structure
It is determined with position, the length of preceding flow-guiding channel can not be more than the half of table body length, the performance of water conservancy diversion before limiting.
