Abstract
The invention belongs to the technical field of flow meters and provides a novel electronic flow meter which is precise in metering as an existing flow meter is great in metering deviation for small flow. The electronic flow meter comprises a housing, an inner sleeve, a connector and a fixing rack, wherein the housing is fixed on the connector through the fixing rack; a water outlet is formed in the inner sleeve; the inner sleeve and the housing are in sealing connection through a sealing ring; the diameter of a water inlet of the housing is greater than that of a water outlet of the housing; a cavity is formed in the housing; an impeller is arranged in the cavity; the impeller can rotate relative to the housing; a magnet is arranged on the impeller; a detecting sensitive element is arranged on the housing. The electronic flow meter has the beneficial effects that flow velocity is increased to generate impact force by designing the diameter of the water inlet of the housing to be greater than that of the water outlet of the housing, and small flow has relatively great impact force to realize a precise metering purpose of the flow meter.
Description
Technical field
The invention belongs to flowmeter technology field, particularly a kind of electronic flow-meter.
Background technology
Usually need in the accurate fields of measurement of some low flow rate liquids and measure accurately, and flow is very little.And now general flowmeter when all there is low discharge measurement deviation comparatively large, just not to measure even at all, and need volume little, and flowmeter at present in China market is all very greatly, directivity is insensitive; Present flowmeter be all exist place vertically, traverse, measured deviation too large or not workable shortcoming when keeping flat.
Summary of the invention
The object of the invention is large for measurement deviation during existing flowmeter low discharge and one that is that provide measures novel electron flowmeter accurately.
The present invention is achieved by the following technical solution:
A kind of electronic flow-meter, comprise shell, inner sleeve, web member and fixed mount, shell is fixed on web member by fixed mount, inside puts and has water delivering orifice, be tightly connected between inner sleeve and shell by O-ring seal, shell water inlet diameter is greater than shell water delivering orifice diameter, there is a chamber in the enclosure, in chamber, impeller is installed, and impeller opposite shell can rotate, impeller is provided with magnet, shell is provided with a detection sensitive element.
A truncated cone-shaped structure is formed between described shell water inlet and shell water delivering orifice.
Described impeller comprises rotation axis and blade, and magnet is established on the rotating shaft, and blade is fixing on the rotating shaft, and rotation axis can opposite shell rotate.
Described blade is six, and the distribution of blade circular array on the rotating shaft.
The annular pawl structure being convenient to connect is arranged with outside the water inlet of shell.
The annular pawl structure being convenient to connect is arranged with outside the water inlet of shell.
Beneficial effect of the present invention: shell water inlet diameter design is greater than shell water delivering orifice diameter by the present invention, produces impulsive force to increase flow velocity; Thus make low discharge all have larger impulsive force, realize flowmeter and measure object accurately.
Accompanying drawing explanation
Fig. 1 is perspective view of the present invention.
Fig. 2 is cut-open view of the present invention.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment
A kind of electronic flow-meter as shown in Figure 1, comprise shell 1, inner sleeve 2, web member 3 and fixed mount 4, shell 1 is fixed on web member 3 by fixed mount 4, inner sleeve 2 has water delivering orifice, be tightly connected by O-ring seal 5 between inner sleeve 2 and shell 1, shell 1 water inlet diameter is greater than shell water delivering orifice diameter, there is a chamber in shell 1, impeller 6 is installed in chamber, and impeller 6 can opposite shell 1 rotate, impeller 6 is provided with magnet 7, shell is provided with a detection sensitive element 8 (electromagnetic flow transducer).A truncated cone-shaped structure is formed between described shell water inlet and shell water delivering orifice.Described impeller comprises rotation axis and blade, and magnet is established on the rotating shaft, and blade is fixing on the rotating shaft, and rotation axis can opposite shell rotate.Described blade is six, and the distribution of blade circular array on the rotating shaft.The annular pawl structure being convenient to connect is arranged with outside the water inlet of shell.The annular pawl structure being convenient to connect is arranged with outside the water inlet of shell.
The design of the bore of liquid-inlet is greater than outlet bore by the present invention, produces impulsive force to increase flow velocity; Adopt the decay that 6 page wheel reduction liquid outlets cause to the distance measuring core wheel to reduce liquid sticky power; The size of reduction core wheel assembly and quality are to reduce friction and viscosity resistance; Reduce the decay of liquid flow forces by swirl channel, reduce friction and the resistance to impact of liquid and passage, the adjustment core wheel width of page and the ratio of injection stream are to reduce the viscosity resistance of liquid; Reduce friction with point cantact between sports apparatus; Adjustment magnetic reduces interference and the obstruction of magnetic field of the earth power;
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention, those ordinary skill in the art simple change and replace be all within protection scope of the present invention.
