Abstract
The utility model provides a translation and target type flowmeter in order to solve the technical problems of complicated structure, big measurement error, low accuracy, poor safety, narrow application range, etc. existing in the existing target-type flowmeter. The technical scheme adopts a target rod double-shrapnel suspension structure and a non-contact type linear Hall magnetic induction structure, eliminating the disturbance of fluid complicated force action to measurement, a target plate always keeps vertical to the flow direction of measured fluid, and thus, the measurement error is reduced obviously, the measuring accuracy is enhanced, the safe handling performance is high, the flow measurement range is wider and the utility model can also be used for the measurement in petroleum and impurity fluid.
Description
Technical field
The utility model relates to a kind of target-type flow instrument improvement technology.
Background technology
Target type meter is as differential pressure type flow meter, stressedly had specific funtcional relationship with flow velocity and calculates and record data such as flow velocity according to it by the target plate that is in the fluid flow cavity body.The stress equilibrium bridge that the transmitter of existing target type meter is made up of power induction foil gauge constitutes, and becomes to send target plate stressed elastic deformation signal with lever target bar or stress tube.The technical problem underlying that prior art exists is: one, it is formed in the structure, the seal isolation mechanism of strain detecting mechanism and fluid chamber is set, the part-structure spare that wherein participates in strain detecting will doublely be done mechanical sealing element simultaneously, in testing because of experiencing the fluid flow forces frequent deformation, be prone to the seal leakage phenomenon, security performance is low; Its two, the pressure condition of bearing detected fluid owing to strain test element is quite complicated to be disturbed greatly, just becomes the error that is difficult in the measurement structure eliminate and disturbs, and causes the measuring error increasing; Its three, the target bar transmits the stressed variation of target plate with lever construction, makes target plate produce angular displacement and moves, and causes target plate and rate of flow of fluid direction out of plumb, this self structure defective has caused its measuring accuracy to be difficult to raising.So in sum, though existing target type meter has the wider characteristics of range of application, the flowmeter survey error is big, precision is low, poor safety performance but because the defective of self strain detecting mechanism structure has caused, thereby be unsuitable for the low discharge measurement range, and be applied to cautiously in inflammable, the explosive fluid measurement environment.
The utility model content
Goal of the invention of the present utility model is to provide a kind of parallel-moving type target type meter that induction becomes censorship survey mechanism structure, improves metering accuracy of simplifying.Parallel-moving type target type meter technical scheme of the present utility model, the major technique content of its technical scheme is: a kind of parallel-moving type target type meter, detected fluid tube chamber one side communicates the flowmeter cavity is set, the axis place of flowmeter cavity hangs and is provided with the target bar, this target bar is hung by flowmeter cavity top naturally by the shell fragment that its symmetria bilateralis is provided with, the target plate that is fixed in target bar lower end is arranged in fluid chamber, and target bar top is provided with the magnetic induction hall sensor corresponding permanent magnet that be provided with, realize sensing change send outer with the flowmeter cavity.
The parallel-moving type target type meter technical scheme that the utility model provides, in the design owing to adopted the two shell fragment hitches of target bar, the detected fluid mobilization is tried hard to recommend moving-target plate and target bar thereof, what target bar and target plate produced is the stressed displacement of translation, so just make the target plate in moving, to keep plumbness with the detected fluid flow direction all the time, thereby avoided target plate in the prior art and fluid flow direction is inconsistent and technology disadvantage that measuring accuracy that cause is low; Another technological merit of the technical program is that its composition is simple in structure, especially its transmitter adopts is that the contactless linear Hall element of magnetic induction substitutes the change of strain chip and send mechanism, promptly eliminated the interference of the complicated power effect of fluid to measuring, measuring error is reduced greatly, and needn't become the seal means that the mechanism for implementing strictness is surveyed in censorship to induction, this mechanism was damaged also can guarantee its safe application performance.So the flow range that the target type meter of present technique structure is suitable for is wideer, also can be applicable in the middle of the measurement of petroleum-type, impurity fluid.
Description of drawings
Fig. 1 and Fig. 2 are respectively the main cut-open view and the cross-sectional view of parallel-moving type target type meter of the present utility model.
Embodiment
As shown in the figure, detected fluid tube chamber 1 one sides communicate parallel-moving type target type meter cavity 8 of the present utility model are set, hang on the axis of this flowmeter cavity 8 and be provided with target bar 3, this target bar 3 is that the two shell fragments 4 by its symmetria bilateralis setting hang and are arranged in the flowmeter cavity 8, the top of flowmeter cavity 8 is fixed on described pair of shell fragment 4 tops, target plate 2 is fixed in the lower end of target bar 3, target bar 3 upper ends are set with a permanent magnet 5, with this permanent magnet 5 corresponding flowmeter cavity 8 outer magnetic induction Hall elements 6 that are provided with common formation transmitter that are positioned at, its change send electric signal as calculated treating apparatus 7 finish conversion of signals, calculate and result's demonstration.
