Description
Technical field
The present invention relates to utilize in the field of flow meters that the detector fluid flow is measured, measures, detects, controlled, employed detector mounting pipe group in the device of adjusting etc.
Background technology
Existing for the fluid ultrasonic measurement, be the linear pattern reflection measurement.
For example, for following situation: existing control to water flow is that mechanical twisting mode is controlled flow valve and realized traffic management and control manually by the metering numerical value of observation water meter.The water meter volume is large, installs affected by environment; Adjusting to current needs manually operation control flow valve, and complicated operation, and inadequate health are not intelligent; And, manually operation control flow valve, the accuracy that flow is controlled is not enough.To this, can conceive a kind of like this scheme of flow control: utilize a pair of ultrasonic detector to come flow detected that (one of them launches ultrasound wave, another is used for receiving ultrasound wave), ultrasonic detector transfers to controller with testing result, controller is according to the traffic demand of testing result and setting, the control flow control valve is realized control to flow, so that actual flow meets the setting demand.
In the above-mentioned this volume control device of enumerating, use the fluid hose that passes through for fluid, and common fluid hose all is straight tube, ultrasonic detector is arranged in this common fluid straight tube.Because all there is certain operating lag in the ultrasonic detector of different sensitivity, this operating lag can make ultrasonic detector that the detection of flow is produced error, length of straight pipe between a pair of ultrasonic detector is shorter, the measuring error that is caused by the operating lag of detector is larger, and accuracy of measurement is lower.Therefore, reduce the operating lag of detector to the impact of accuracy of measurement, common adoptable solution is to select longer straight tube so that a pair of detector arrangement in straight tube after, distance apart increases, thereby reduces the operating lag of detector to the impact of accuracy of measurement.This mode that reduces to affect all is feasible under normal conditions.
But if fluid hose is long, meeting is so that the height of volume control device or oversize on other direction, under the limited environment of some installing space, be difficult to realize normal mounting, destruction installation environment that perhaps will be to a certain degree, installation difficulty is large and cost is high.If shorten the length of fluid hose, measuring error and control precision certainly will have been increased again.
Summary of the invention
For the detector mounting pipe group of solution in flow measurement, metering, detection, control or regulating device etc. can not adapt to accuracy of measurement is required the again technical matters of limited situation of high installing space, the invention provides a kind of detector mounting pipe group.
The present invention for the technical scheme that provides is provided is: a kind of detector mounting pipe group, comprise draft tube, and described draft tube comprises influent stream pipe section and the outflow tube section that connects docking; The angle that described influent stream pipe section and described outflow tube section form in both junctions greater than 0 °, less than 180 °, described influent stream pipe section is provided with the first flow detector away from an end of the junction of itself and described outflow tube section, described outflow tube section is provided with the second flow probe away from an end of the junction of itself and described influent stream pipe section, is provided with the first reflection part in the junction of described influent stream pipe section and described outflow tube section; The signal that described first flow detector or described the second flow probe send is received by the other side after the reflection of described the first reflection part, if that is: the first flow detector is launched signal, this signal is received by the second flow probe after the reflection of the first reflection part; If the second flow probe is launched signal, this signal is received by the first flow detector after the reflection of the first reflection part.
