Abstract
The invention discloses a variable flow wedge shaped flowmeter and belongs to the field of flow measuring technology. A problem of a failure to change flow measuring scope is solved. The flowmeter comprises a flange, a pressure taking pipe, a wedge, a differential pressure transmitter and a measuring pipe. The wedge is connected with the measuring pipe via at least two fastening screws. The upper part of the wedge is of an arc-shaped structure and is in seamless connection with the inner wall of the measuring pipe. By loosening the fastening screws, taking the wedge, putting into a new wedge and fixing the new wedge with the fastening screws, the original wedge can be replaced. According to the invention, by changing the wedge fixedly welded in a traditional flowmeter with a replaceable wedge fixed by the fastening screws, so during use, by changing the wedge, the flow measuring scope can be changed according actual flow volume; flow measurement is kept in the precise scope all the time; and loss of pressure can satisfy technological requirements.
Description
One, technical field the invention belongs to the field of measuring technique of flow, particularly relates to a kind of wedge flow meter.
Two, background technology wedge flow meter is a kind of novel throttling differential pressure type flow measurement instrument, and it can carry out high-precision flow measurement under the fluid situations of high viscosity, low reynolds number (Reynolds number > 500 can use); Unrivaled advantage and irreplaceable effect is had compared with low, that flow is little, caliber is large flow measurement occasion at flow velocity.But the wedge of wedge flow meter is than being disposable design and welding production, voussoir can be able to not be changed as orifice plate, on the one hand because flow value during design is often bigger than normal, when finding after installation that actual flow is too little, not in the flow measurement range of flow meters work; Exceed measurement range again along with production capacity increases flow on the other hand, continue to measure as strengthened differential pressure pick-up, crushing is too large, does not meet technological requirement.
Three, summary of the invention the object of this invention is to provide a kind of changeable flow wedge flow meter, solve the problem that can not change flow measurement range, it comprises flange, pressure pipe, voussoir, differential pressure transmitter and measuring tube, voussoir is connected with measuring tube by trip bolt, at least be connected with measuring tube by 2 trip bolts, voussoir top is circular arc, connect with wall seamless in measuring tube, and by trip bolt and the seamless link of measuring tube inwall, when changing voussoir, first can unclamp trip bolt and take out voussoir, then put into new voussoir trip bolt and fix.The present invention changes the voussoir be welded and fixed in conventional wedge flowmeter as the fixing replaceable voussoir of trip bolt into, during use, according to actual flow size, flow measurement range can be changed by changing voussoir, flow measurement is remained in accuracy rating, and crushing can meet technological requirement.
Four, description of drawings 1 is the axial cut-open view of a kind of changeable flow wedge flow meter of the present invention;
Fig. 2 is a kind of changeable flow wedge flow meter of the present invention radial cross-section.
Five, embodiment is described further a kind of changeable flow wedge flow meter of the present invention below in conjunction with Fig. 1 and Fig. 2, it comprises flange 1, pressure pipe 2, voussoir 3, differential pressure transmitter 4 and measuring tube 6, voussoir 3 is connected with measuring tube 6 by trip bolt 5, at least be connected with measuring tube 6 by 2 trip bolts 5, voussoir 3 top is circular arc, connect with wall seamless in measuring tube 6, and by trip bolt 5 and the seamless link of measuring tube 6 inwall, when changing voussoir 3, first can unclamp trip bolt 5 and take out voussoir 3, then put into new voussoir 3 trip bolt 5 to fix.
