Abstract
A cantilever flow sensor belongs to the fluid measuring device technical field. The present inserted flow sensors mainly comprise flute-shaped tube type, tangent hung swing type and vertex type. The application range is limited because the present sensors can not measure low-flow speed and high-temperature fluid with great viscosity and high dust content. The technical proposal of the utility model is that a screw stress arm 1 is vertically penetrated through and fixed on a load transfer shaft 7; a drive sensor 5 is connected with the load transfer shaft 7 and the drive sensor 5 can be a pressure sensor, a torque sensor or a weighting sensor; the load transfer shaft 7 is connected with a shell 3 by a flexible shaft connector 4; the load transfer shaft 7 is equipped in two bearings 6 on the shell 3; the screw stress arm 1 is extended into a pipe wall 2. The utility model is characterized by a rational practical design and ingenious novel conception and the utility model can measure the low-flow speed and high-temperature fluid with great viscosity and high dust content; the sensor has a high sensitivity.
Description
Technical field: the utility model relates to fluid metering instrument technical field, is the cantilevered flow sensor more specifically.
Background technology: at present the plug-in type flow transducer that uses mainly contains flute-form, tangentially outstanding wing formula and whirlpool rank formula, because that it can not measure viscosity is big, and the dustiness height, low flow velocity and high temperature fluid, range of application is restricted.
Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of cantilevered flow sensor of design.Its technical scheme is: screw rod is vertically passed by the arm of force 1 and is fixed on the force transmission shaft 7, and dynamic pickup 5 is connected with force transmission shaft 7, and dynamic pickup 5 can be pressure transducer, torque sensor or LOAD CELLS; Elasticity connecting shaft body 4 is connected force transmission shaft 7 with housing 3; Force transmission shaft 7 is contained in two bearings 6 that are arranged on the housing 3, and screw rod is stretched in the duct wall 2 by the arm of force 1.The advantage of this utility model is: the reasonable in design practicality, and the novelty that is skillfully constructed, the installation that can not stop production, measurable viscosity is big, dustiness height, low flow velocity and high temperature fluid, this transducer sensitivity height.
Description of drawings: Fig. 1 front view, Fig. 2 is subjected to the arm structure synoptic diagram for the screw rod of band expander, and Fig. 3 is at Fig. 2 A-A place cut-open view, and Fig. 4 is subjected to the arm structure synoptic diagram for the screw rod of band elliptical vessel, and Fig. 5 is at Fig. 4 A-A place cut-open view.In the accompanying drawing: 1, screw rod is subjected to the arm of force, and 2, duct wall, 3, housing, 4, elasticity connecting shaft body, 5, dynamic pickup, 6, bearing, 7, force transmission shaft, 8, wiring board, 9, upper end cover, 10, expander, 11, elliptical vessel.
Embodiment: screw rod is vertically passed by the arm of force 1 and is fixed on the force transmission shaft 7, and dynamic pickup 5 is connected with force transmission shaft 7, and dynamic pickup 5 can be pressure transducer, torque sensor or LOAD CELLS; Elasticity connecting shaft body 4 is connected force transmission shaft 7 with housing 3; Force transmission shaft 7 is contained in two bearings 6 that are arranged on the housing 3, and screw rod is stretched in the duct wall 2 by the arm of force 1.The cantilevered flow sensor is to be subjected to the arm of force 1 and fluid collision principle by a thinner screw rod, and the viscosity higher of fluid, higher dustiness, elegance can not influence the flow of rod member by the stressed fluid that shows.
Cantilevered flow sensor project organization as shown in drawings.Screw rod is rotated around axial line by the arm of force 1, and suffered fluid momentum is acted on dynamic pickup 5 by axle 7, and dynamic pickup 5 will be exported an electric signal relevant with flow.Increasing screw rod is subjected to the arm of force 1 length will increase electrical signal intensity.For making screw rod be subjected to the stressed width of the arm of force 1 to have two kinds because of fluid density changes the respective change concrete grammar
A, screw rod are subjected to the arm of force 1 termination to be designed to the variable pipe of diameter, and expander 10 is set in the pipe, and expander 10 volume change can change the caliber size.Expander 10 volumes change because of fluid density is different, thereby change the stressed width of rod member, adjust the stressed size that screw rod is subjected to the arm of force 1 automatically.
B, screw rod are subjected to the arm of force 1 termination to be designed to elliptical vessel 11, elliptical vessel 11 is subjected to buoyancy, move along the rod member axial direction, and under the effect of the worm and gear kind of drive, make oval rod member rotate an angle, so just change screw rod and be subjected to the positive stressed width of the arm of force 1, thereby adjusted the stressed size that screw rod is subjected to the arm of force 1 automatically.
