The utility model is mainly composed of a casing (1), a spherical shunting element (2), a worm wheel (3) and a signal transducer (4) or a casing (1), a cylindrical shunting element (2) and a meter (3). The utility model can be directly arranged in pipes with large diameter for measuring and controlling the flow of the fluid. The utility model has the advantages of simple structure, convenient installation and operation, few errors, lower energy consumption in the measuring process and wider measuring range, which can be used for the occasions of measuring and controlling the big flow of the fluid in the industries.
Description
The utility model belongs to the meter fluid flow instrument, and especially shunt type flowmeter is applicable to the occasion that fluid flow in the large diameter pipeline is measured and controlled.
Before the utility model is made, fluid flow in the large diameter pipeline is measured and control, because all there are many difficulties in heavy caliber flowing meter at aspects such as manufacturing and demarcation, when measuring, there is the excessive deficiency of energy consumption again, be difficult to implement, therefore the situation of heavy caliber flowing meter use at present is few, fluid flow in the industrial large diameter pipeline, the general employing goes out some subtubes than minor diameter at the trunk line parallel branch, measures and controls with restriction flowmeter respectively then.Restriction flowmeter is most typical to be orifice flowmeter, mainly the plate and the pressure chamber of opening a circular hole by central authorities constituted, in measuring channel, insert orifice flowmeter perpendicular to fluid flow direction, fluid produces a differential pressure by orifice plate circular hole front and back end, the size of this differential pressure can be represented the size of tube fluid flow.This kind flowmeter structure is simple, and therefore application is wider aborning, but energy consumption is still excessive in the measuring process, and it is wrong when poor when differential pressure transmitter to be in operation, and just is difficult to find, thereby can not get correcting timely, be easy to generate the error of measurement of fluid flow and control, influence implementation result.
Task of the present utility model is that a kind of structure of design is comparatively simple, in the mensuration process energy consumption lower, directly place large diameter pipeline to be used for that fluid flow is measured and the shunt type flowmeter of control.
A kind of shunt type flowmeter, mainly by housing (1), spherical vent diverter (2), worm gear (3), signal transducer (4) or by housing (1), cylindrical vent diverter (2), gauging table (3) constitutes, the spherical vent diverter (2) that is arranged in the housing (1) is the spheroid that a ball centre along continuous straight runs has an aperture, device worm gear (3) in this aperture, spherical vent diverter (2) installs little pipe respectively in two ends up and down, the other end of the little pipe in lower end is fixed on the center on the housing (1), center device signal transducer (4) and be fixed on center on the housing (1) in the little pipe in upper end, the cylindrical vent diverter (2) that is arranged in the housing (1) is the little pipe of device dividing plate in the pipe, this little pipe is positioned at housing (1) center along continuous straight runs and respectively opens an aperture in both sides, with a dividing plate two apertures are separated separated into two parts fully in the little pipe, these cylindrical vent diverter (2) two ends are connected with gauging table (3) respectively by the roundlet pipe and are fixed on center on the housing (1).The aperture of spherical vent diverter (2) or cylindrical vent diverter (2) tapping is toroidal.
Shunt type flowmeter of the present utility model compared with prior art, can directly place large diameter pipeline to be used for the mensuration and the control of fluid flow, have simple in structure, advantages such as energy consumption is lower in easy to install and use, the mensuration process, measurement range is big, error at measurment is little can be widely used in the occasion of big flow measurement of industrial fluid and control.
