Abstract
The utility model discloses a metal pipe horizontal-type float flowmeter. The metal pipe horizontal-type float flowmeter is characterized in that a measuring mechanism (B) is composed of a measuring pipe (1), a guide rod (2), a front support (3a), a rear support (3b), a conical float (4), a front float stabilizing spring (5a), a rear float stabilizing spring (5b) and a pore plate (6), the conical float (4) is installed on the guide rod (2) in a sliding fit mode through a central hole, and magnetic steel (40) is installed in the conical float (4). The metal pipe horizontal-type float flowmeter is reasonable in structure, the measuring mechanism (B) is completely horizontal, fluid does not change in flowing direction, flowing resistance is small, differential pressure losses are small, measuring can be conducted accurately while the full-scale flow is small, the range of flow is expanded, working is reliable and installation, use and maintenance are convenient.
Description
Technical field
The utility model relates to flowmeter, particularly metal pipe float flow meter.
Background technology
Metal pipe float flow meter is the instrument for flow measurement, can measure liquid, gas and steam.
Metal pipe float flow meter is comprised of measuring mechanism and converter two parts.Its principle of work is: float is located in vertical measuring tube, and medium flows into from measuring the lower end of organ pipe, from upper end, flows out, effect due to fluid, float upper and lower end face produces a differential pressure, and this differential pressure is the raising force of float, when the lift being subject to when float and float gravitational equilibrium, float rests on a certain position, magnet steel coupling on magnet steel on float and converter shaft, by Electromagnetic Coupling System, converts flow value to, by pointer and index dial, indicated, or output 4-20mA current signal.
When common suspended body flowmeter is used, the measuring tube of flowmeter must be arranged on the pipeline section of capwise, and fluid media (medium) is from bottom to up by the measuring tube of flowmeter.Because field working conditions condition often need to be installed metal pipe float flow meter on horizontal pipe.So its structure of existing horizontal metal tube float flow meter is a kind of distortion of vertical stratification, just in the upper and lower side connection of measuring tube, offer horizontal liquid inlet and outlet pipe, although realized, be connected on horizontal pipe, a medium left side is entered the right side and is gone out, but middle measuring tube position is still vertical stratification, this kind of structure changes media flow form, the media flow bad stability that enters measuring tube, the pressure loss strengthens, and the measuring accuracy of suspended body flowmeter is reduced.
Utility model content
The object of the invention is for above-mentioned existing metal tube
floatthe shortcoming of flowmeter is not enough, and what provide is a kind of rational in infrastructure, reliable operation, install, working service easily metal tube horizontal suspended body flowmeter measuring mechanism and use the metal pipe float flow meter of this measuring mechanism.
This metal pipe float flow meter comprises converter A and measuring mechanism B, it is characterized in that: measuring mechanism B comprises measuring tube 1, guide pole 2, fore-stock 3a, after-poppet 3b, taper float 4, front float stabilizing spring 5a, rear float stabilizing spring 5b, orifice plate 6, fore-stock 3a and after-poppet 3b are fixedly mounted on respectively the both ends, left and right in measuring tube 1, the two ends, left and right of guide pole 2 are fixed and are connected with center pit on after-poppet 3b with fore-stock 3a respectively, taper float 4 is slidably installed on guide pole 2 by its center pit, in taper float 4 bodies, be provided with magnet steel 40, float stabilizing spring 5a before installing between fore-stock 3a and taper float 4 front ends on guide pole 2, float stabilizing spring 5b after installing between after-poppet 3b and taper float 4 rear ends on guide pole 2, corresponding taper float 4 is at the interior fixed installation orifice plate 6 of measuring tube 1, circular hole 61 on orifice plate 6 coordinates with the rear end cone top part 41 of taper float 4.
The utility model medium flows into from the left end of measuring tube 1, taper float 4 is acted on guide pole by fluid to move right, medium is from the annular space surface current mistake of 6 of taper float 4 and orifice plates, and taper float 4 is subject to when moving right that the acting in conjunction of its front float stabilizing spring 5a and rear float stabilizing spring 5b is stable to stop.
The utility model is rational in infrastructure, reliable operation, and installation, working service are conveniently, in taper float 4 bodies, be provided with magnet steel 40 and be coupled with the magnet steel on converter A shaft, by Electromagnetic Coupling System, be directly changed into flow value, by pointer and index dial, indicated, or output 4-20mA current signal.
It is complete horizontal that measurement of the present invention forms B, and the metal pipe float flow meter fluid of prior art change import and export position does not have the change on flow direction relatively, thereby makes fluid flow resistance little, and difference pressuring loss is very little.Output signal and flow are linear, at full scale flow hour, also can accurately measure, and have expanded the rangeability of flow.
