Abstract
The invention provides an intelligent turbine flowmeter with redundant measurement function, comprising a shell, an impeller, a signal converter and a regulating valve; wherein the impeller is arranged in the shell, the regulating valve is arranged at one end of the shell in an integration way. And the intelligent turbine flowmeter with redundant measurement function also comprises two ultrasound probes which are respectively arranged and fixed on the shell in the integration way. The invention has the beneficial effects that an integrative turbine flowmeter, regulating valve and ultrasound probe structure is adopted, redundant function of continuous measurement can also be realized even the impeller of the turbine flowmeter is in blockage fault, trade settlement dispute is reduced, maintenance response time of the turbine flowmeter is increased, and leakage points of flow measurement and control pipe line are reduced.
Description
Technical field
The present invention relates to a kind of fluid measurement instrument field, but a kind of intelligence turbine flowmeter of redundant measurement particularly.
Background technology
Application along with new forms of energy; In the city, the small towns used tap water, pipeline hot water and pipe gas widely; Particularly the application of these new forms of energy of rock gas has brought convenience to the user; Present stage, the kind of gas discharge measurement instrument was more; Turbo flow meter is exactly wherein a kind of, because compact conformation, good reproducibility, the rangeability of turbo flow meter are wide, precision is high, element zero point drift is little, the characteristics that antijamming capability is good have obtained the application widely on the natural gas flow measuring field.But; The shortcoming of typical turbine flowmeter also becomes increasingly conspicuous in the metering process of rock gas, mainly be the impeller of present turbo flow meter when card is stifled because not energy measurement and metering causes continuous data and actual flow generation deviation; Cause trade dispute; At present, also have method to solve, but this method install complicacy additional, has increased the many places leakage points, has improved the cost of equipment purchasing greatly through adding to adorn an identical instrument.Therefore the problem of typical turbine flowmeter existence need be solved.
Summary of the invention
But the intelligence turbine flowmeter that the purpose of this invention is to provide a kind of redundant measurement solves in the turbo flow meter observing and controlling process, can not continuous measurement during impeller jam fault, and pipeline leakage point is many, overhauls the untimely problem that very easily produces trade dispute.
For realizing above-mentioned purpose, the present invention adopts following technical scheme to solve above technical matters, but a kind of intelligence turbine flowmeter of redundant measurement; Comprise housing, impeller, signal converter and variable valve; Impeller is installed in the housing, the integrated end that is installed in housing of variable valve, and signal converter is handled measurement and control signal; Also comprise two ultrasonic probes, be fixed on the housing respectively integratedly.
Two ultrasonic probes are fixedly mounted on impeller and the adjusting housing between cutting down; Said ultrasonic probe is installed with the axial one-tenth miter angle of housing; Be installed in housing both sides radially respectively, and the alignment of the longitudinal center line of two ultrasonic probes, remain on housing shaft in same plane.
Ultrasonic probe can screw thread or welded and installed.
Ultrasonic probe can realize that the flow of convection cell carries out redundant measurement, when impeller jam fault appears in turbo flow meter, after through the universal circuit module turbo flow meter signal and ultrasonic probe signal being compared, realizes continuing metering with ultrasonic probe.
The invention has the beneficial effects as follows and adopt incorporate turbo flow meter, adjusting to cut down and the ultrasonic probe structure; Also can continuous measurement when being implemented in turbo flow meter impeller jam fault; Reduce the trade settlement dispute; Increase the maintenance reaction time of turbo flow meter, reduced the leakage point of flow measuring and controlling pipeline.

Embodiment
Specify the preferred embodiments of the present invention below in conjunction with accompanying drawing.
Present embodiment such as Fig. 1, Fig. 2, shown in Figure 3, but a kind of intelligence turbine flowmeter of redundant measurement comprise housing 1, impeller 7, signal converter 3, regulate and cut down 4 and ultrasonic probe 5,6.Impeller 7 is arranged in the housing 1, and the spool of variable valve 4 is arranged in the housing 1 of one section lengthening, and housing 1 one ends at an end of location shell 2 and spool place are connected as a single entity through flange; Housing 1 also is provided with flange so that be connected with pipeline with the other end of location shell 2; Adjusting is cut down 4 and is chosen as motorized adjustment and cuts down, and also can select pneumatic or surge to regulate to cut down according to the observing and controlling needs, and ultrasonic probe 5,6 is installed with the axial one-tenth miter angle of housing 1; Be installed in housing 1 both sides radially respectively; And the alignment of the longitudinal center line of two ultrasonic probes 5,6 remains in the housing 1 axial same plane, and ultrasonic probe 5,6 and housing 1 are through being threaded; Ultrasonic probe 5,6 carries protective casing, establishes protective casing in addition also can for ultrasonic probe 5,6.
The flow signal of turbo flow meter is handled the back through signal converter 3 and is combined secondary instruments to carry out intelligent display, teletransmission, communication and carry out observing and controlling through variable valve; Ultrasonic probe 5,6 is in the energising redundant state when flat; When the impeller 7 of turbo flow meter breaks down because of jam; Turbo flow meter signal and ultrasonic probe signal compare through the comparator circuit module that is arranged in the signal converter 3; Make signal converter 3 select to adopt the measured value of ultrasonic probe 5,6, thereby do not interrupt flow measurement and accumulative total, help striving for the repair time and don't influence feed because of impeller 7 jams of turbo flow meter; Eliminate the trade dispute that the flow metering error causes, ultrasonic probe 5,6 incorporate mounting structure on housing 1 has reduced the leakage point of Flow Measuring System well in addition.
