Description
Technical field
The utility model relates to the industrial fluids flow measurement, specifically is used for the ultrasonic vortex shedding flow meter of a kind of new plug-in of liquid, gas flow measurement, metering.
Background technology
Along with the development and the water resources management requirements of one's work of heat supply undertaking, the measurement of large-caliber flow is more and more important.Chinese patent ZL02289091.2 discloses a kind of ultrasonic Doppler vortex shedding flow meter.It is to be oppositely arranged emission, reception sonac in the fluid line periphery, is provided with the vortex shedder that produces eddy current at pipe interior, and vortex shedder is positioned at the upstream that liquid medium flows to, and the doppler ultrasound sensor is positioned at the downstream of vortex shedder.Fluid in pipeline produces eddy current through the vortex street generator, the ultrasonic Doppler sensor is produced generally rein in effect and measure.The vortex shedding flow meter of this structure be in pipeline center because body takes place, and sonac is positioned at the pipeline periphery, so, eddy current signal is subjected to the influence of direct current fluid in the pipeline, causes the measured data accuracy of sonac low, the flowmeter poor anti jamming capability.
Chinese patent ZL02242807.0 discloses the whole plug-in type vortex shedding flow meter of a kind of vortex shedder, its structure is to connect the vortex street detection bodies in the supporting linkage lower end, the connecting link upper end passes support from the pipeline that is provided with ball valve and seal assembly and connects the table body, wears lead connection table body and detection bodies in the supporting linkage.Its shortcoming is a no affixed point between connecting link lower end and tested pipeline, and therefore, under the swash of wave effect of fluid, the vortex street detection bodies of connecting link lower end tends to do slight swing, thereby causes the test result error to strengthen.And directly with connecting link lower end and tested pipeline affixed after, cause trouble can for again the maintenance that continues to flow.
The utility model content
The purpose of this utility model just provides the ultrasonic vortex shedding flow meter of the strong new plug-in of a kind of antijamming capability, to improve measuring accuracy.
The utility model is achieved in that the structure of this new flowmeter is the following termination vortex street detection bodies at supporting linkage, the upper end of supporting linkage is passed pedestal and is connect the indicator gauge body, connect the indicator gauge body on the lead of cross-under in the supporting linkage, connect the vortex street detection bodies down.The vortex street detection bodies is made up of stream tube entire body, vortex shedder and ultrasonic transmitter and ultrasonic receiver, vortex shedder is the trapezoidal column structure, radially be welded in the stream tube entire body, ultrasonic transmitter and ultrasonic receiver are installed in the flow body sidewall that the body downstream takes place.
When the utility model uses, with the whole pipe under test center that is complementary of inserting of vortex street detection bodies.When fluid flows through, the downstream that body takes place in the flow body pipeline produces whirlpool, be positioned at the ultrasonic transmitter that flow body sidewall symmetry installs, the signal that ultrasonic receiver is gathered only limits to take place the whirlpool signal that body produces, thereby got rid of that direct current fluid exerts an influence to the whirlpool signal and the measuring error brought, and then improved the accuracy of detection of flowmeter.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the ultrasonic vortex shedding flow meter of the utility model plug-in type is to connect ultrasonic vortex street detection bodies 4 in the lower end of supporting linkage 5, the upper end of supporting linkage is passed pedestal 1 and is connect indicator gauge body (not shown), the open butt joint solid welding on pedestal 1 lower end and the tested body.Connect indicator gauge body (not shown) on the lead of cross-under in the supporting linkage, connect vortex street detection bodies 4 down.Vortex street detection bodies 4 is made up of stream tube entire body 42, vortex shedder 43 and ultrasonic transmitter and ultrasonic receiver, vortex shedder 43 is the trapezoidal column structure, radially be welded in the stream tube entire body 42, ultrasonic transmitter and ultrasonic receiver are installed in flow body 42 sidewalls that the body downstream takes place.
Ultrasonic transmitter and ultrasonic receiver are symmetrical perforates on the flow body tube wall that the body downstream takes place, and in welding probe socket 41, two probe sockets emission are installed respectively in the hole, receive the ultrasonic probe assembly; The probe socket 41 outer sleeve pipes 45 that are welded with respectively, last sleeve pipe 45 joins running casing 45 external welding end caps 44 with supporting linkage 5.
On pedestal 1, be provided with connecting link stationary installation 2.The connecting link stationary installation can adopt the structure of any one convenient locking of the prior art and pine oil, as common worm drive.But a kind of concrete implementation is symmetrical perforate on the barrel of pedestal 1, connects respectively outside the hole in a sleeve pipe 21, two sleeve pipes respectively that cross-under has screw rod 23, and the screw rod middle part has convex shoulder to be connected on the reducer of sleeve pipe 21 endoporus, sealing-in end cap 22 on the external port of sleeve pipe 21; Cross-under has tapped push pipe 24 respectively in two sleeve pipes 21, and the leading portion of screw rod 23 is screwed in the push pipe 24.Between the surface of contact of the surface of contact of sleeve pipe 21 and end cap 22 and screw rod and end cap, install sealing gasket additional.The application of force when screw rod outer end is made prism with convenient the rotation.End at screw rod connects locking dome 25 with bolt, and screw rod is in metastable state during in the normal use of dependable flow, thereby makes push pipe hold out against connecting link all the time.
Adopt this structure, the gap of supporting linkage between two push pipes passed.Sleeve pipe and end cap play position-limiting action to screw rod, during rotary screw, and the revolution of screw rod original position, reciprocating with the push pipe that screw rod spins.Receipts then clamp supporting linkage in two push pipes, and connecting link is played fixation; Contra rotating screw, two push pipes retreat to certain position outward, and the detection bodies that connecting link and following termination thereof are established is passed through in two push pipe gaps, and connecting link and detection head withdraws from smoothly when keeping in repair conveniently to continue to flow.The utility model maintenance that both can realize easily continuing to flow can make measurement more accurate again.Be fit to very much the measurement of large diameter pipeline rate-of flow, be suitable for large tracts of land and promote the use of.
