Abstract
The present invention relates to a kind of gas turbine meter for having carried rotation baffle, it is characterised in that the front end of turbine is mounted with that the gas that can be flowed through produces the baffle of the conical helical pattern of rotary thrust in table body.2. it is different from the axially vertical baffle for blowing to turbine of current air-flow straight line, the surface that blade is vertically blowed into the air-flow generation rotating vortex in table body of the invention that allowed using a baffle that gas medium can be allowed to produce rotation, reduce the loss of axial force caused by blade, measured so as to increase the torque of turbine so that can be rotated in the case of in small air-flow, expand the scope of flowmeter metering.
Description
Technical field
Patent of the present invention is related to a kind of gas turbine meter for having carried rotation baffle.
Background technology
The baffle of current gas turbine meter is straight line water conservancy diversion, exactly allows the air-flow of medium along linear
Guide plate blows to turbine along table intracoelomic cavity is axially vertical, and the blade of turbine and the direction of air-flow tilt certain angle by gas
Axial force be converted into tangential force so as to drive the rotation of turbine, because the angle of impeller and the flow direction of air-flow have certain angle
Thus there is very big a part of axial force to be transformed into tangential force, therefore be just difficult to driving leaf in the case of air-flow is less
The rotation of wheel influences the scope of measurement so as to which the gas being difficult on low discharge measures.
The content of the invention
Different from the axially vertical baffle for blowing to turbine of air-flow straight line of current medium, the present invention can be allowed using one
The baffle that gas medium produces rotation allows into the air-flow generation rotation in table body and vertically blows to the surface of blade, reduces leaf
The loss of axial force caused by piece, so as to increase the torque of turbine so that progress can be rotated in the case of in small air-flow
Metering, expand the scope of flowmeter metering.
Brief description of the drawings
Fig. 1 is the schematic view of the mounting position in flowmeter of the present invention in specification, and figure number is that 001 map title is front view,
Fig. 2 is the structural representation of the present invention, and figure number is that 002 map title is front view, and Fig. 3 is Fig. 2 left side view, and figure number is 003 figure
Entitled left view, Fig. 4 are the 3-D views of the present invention, and figure number is that 004 map title is graphics.Sequence number description of contents in figure：1 is
Rise rotation baffle, 2 be turbine, 3 be table body, 4 be conveyor screw, 5 be centring ring, 6 be locating rod.
Present invention can be realized by following scheme：
Conveyor screw 4 is that a bullet front end is arc transition, has helicla flute on bullet, helicla flute can make to flow through
Gas produce rotation.The direction of spiral makes air-flow vertically blow to the surface of turbo blade.
Conveyor screw 4 is connected with centring ring 5 by locating rod 6 and keeps concentric.
Centring ring 5 is a cylindrical tubular body, and excircle part is fitted close with table body 3, ensures conveyor screw 4 and table body
3 inner chambers are concentric.
Claims (2)
