Description
Technical field
The invention belongs to acoustics, field of sensing technologies, particularly utilize ultrasonic detecting technology to combine flow break-make control technology, specifically is a kind of ultrasonic flow rate metering instrument and flow control system.
Background technology
The ultrasonic flow instrument is to be principle with " velocity contrast method ", measures the instrument of fluid flow in the pipeline section pipe.It has adopted advanced multiple-pulse technology, signal digitalized treatment technology and error correcting technique, makes flow instrument more can adapt to on-the-spot environment, measures more convenient, economical, accurate.Can be widely used in fields such as oil, chemical industry, metallurgy, electric power, plumbing.
Existing ultrasonic flow instrument; Have reflective and two kinds of correlations by hyperacoustic emission and receive mode, characteristics are the measuring tubes that all require a certain-length and caliber, and caliber is more little; Fluid velocity in the pipe can be fast more; The flow field is stable more, and the length of measuring tube is long more, and the precision of corresponding metering instrument is just high more.
Based on above characteristics, the existing fluid pipe network that adopts the metering of ultrasonic flow instrument, its break-make control method generally is employed in the outer equipped Self controlling valve of the certain caliber distance in instrument front and back, in order to avoid influence the measurement of instrument, requirement has bigger on-the-spot installing space.When realizing that like need convection cell carries out intelligently connecting or disconnecting control, between instrument and operation valve, set up the control communication separately, increase installation cost thus, and later maintenance cost.
Other also has a kind of control system that Self controlling valve is integrated into instrument table body water side; This system is because table body and Self controlling valve one; Therefore structure is comparatively compact, and installation and Communication Control are convenient, but because the too small meeting of valve apertures is influential to instrument inner fluid flowing field stability; The latus rectum of valve must be accomplished consistent with caliber or bigger; This moment, latus rectum increased, and the required torque of valve break-make can become greatly, needed to dispose the normal operation that can provide driving mechanism and more jumbo battery than large torque to guarantee this system.
Summary of the invention
Goal of the invention: the present invention is for overcoming above-mentioned defective, provide a kind of easy for installation, measure accurately, volume is little, control is simple and reliable ultrasonic and flow control system.
Technical scheme: a kind of ultrasonic and fluid break-make control integrated approach comprise control module 1, ultrasonic device 3, fluid break-make control device 2.The topworks of said fluid break-make control device is positioned at the measuring tube inside of ultrasonic device, and topworks is provided with the hole that the both sides opening runs through topworks, and the aperture of topworks is more than or equal to the measuring tube aperture.The hole cross section of running through topworks includes but not limited to circle, ellipse, square, rectangle, and rhombus is trapezoidal etc.When topworks rotates to certain angle, the center line of hole coincides with the center line of measuring tube or when parallel, fluid flow is maximum; When topworks's continuation rotation, the center line of hole and measuring tube center line angle increase gradually, when vertical; Fluid flow diminishes gradually, until being zero.
Said control module 1 is to receive and handle the velocity information of ultrasound wave in fluid by signal Processing and mimic channel; Record time difference through time chip; Deliver to the information such as instantaneous delivery that microprocessor calculates fluid, these information can directly be presented on the instrument through data display circuit, or import in the user's data storehouse through communicating circuit is long-range; Simultaneously can set requirement by the user, convection cell break-make control device 3 is operated.Said user sets and requires to refer to the user through telecommunication, IC-card sensing, the communicating circuit of communication modes Access Control modules (1) such as infrared emission, the setting that microprocessor is carried out.
Said ultrasonic device 3 is made up of pipeline section 3.4, transducer 3.3, catoptron 3.1, measuring tube 3.2; Said transducer 3.3 tool ultrasonic emitting and receiving functions; Receive ultrasound wave by 3.1 → the second transducers of first transducer 3.3 emission ultrasound wave → catoptron 3.1 → measuring tube, 3.2 → topworks, 2.1 → measuring tube, 3.2 → catoptrons 3.3; Draw the flow information of fluid through control module 1; When fluid break-make control device 2 is carried out the shutoff operation, control module 1 will be controlled the metering computing that ultrasonic device 1 stops convection cell.
Said ultrasonic device 3 is reflective measurement structure, and this device can be used for the correlation measurement structure equally, promptly carries out hyperacoustic transmitting and receiving without any catoptron between two transducers.
Said fluid break-make control device 2 is made up of topworks 2.1, transmission shaft 2.2, driving mechanism 2.3; When control module 1 is set requirement by the user; When this device is carried out the make-break operation requirement, drive transmission shafts 2.2 rotations, make topworks 2.1 carry out make-break operation by driving mechanism 2.3.
Because topworks 2.1 is positioned within the measuring tube 3.2; And measuring tube 3.2 is because of the measurement characteristics of ultrasonic flow instrument; Measuring tube 3.2 can have certain undergauge under the situation that the pressure loss allows; Therefore the aperture of topworks 2.1 can accomplish identical with measuring tube 3.2 apertures, to reach the requirement that reduces driving mechanism 2.3 output torques.
The invention has the beneficial effects as follows: the installation requirement space is little, and is convenient for installation and maintenance, and cost is low, and measuring accuracy height and break-make control are simple.
