Abstract
The disclosed water meter is composed of measuring mechanism (MM), indicating mechanism, shell and closure. Main characters are that MM is installed inside body of meter; rectification wing wheel is installed inside measuring cavity (MC) of MM; there is driving gear (or magnet steel) on up end of axle of wing wheel. Being distributed on base of MC circle wise by using supporting axle as center, diversion holes lead water flow to the wing wheel. Lower end of diversion holes is connected to the collecting chamber (CC). Water inlet of CC is connected to MC in coaxial. A non-return disk covers the inlet of CC. There are one or more shunting pores on sidewall of MC. One end of the pores and inlet of CC are connected to bowl shaped filter screen, and outlet at up part of MM is connected to outlet on shell. Advantages are: smaller pressure loss than spiral wing type meter, higher sensitivity than aerovane wing type meter, high wearability etc.
Description
Technical field
The invention belongs to discharge metering field, relating in particular to bore is the water meter of 8mm to 50mm.
Background technology
At present, the water meter of living standard of urban and rural population water metering, great majority are to adopt rotor water gauge.The principal feature of this water meter measurement mechanism is: the blade of impeller is straight, and current impact the impeller rotation along the impeller tangential direction, the stress surface of blade all with the parallel axes of this wing wheel; Measuring on the chamber wall in chamber has several water conservancy diversion inclined holes, and the tangential direction that the current that guiding comes from pod apertures are circumference is punched on the stress surface of blade, to drive the wing wheel rotation; The transmission gear on wing wheel wheel shaft top drives indicating mechanism and measures.Problem is: impeller also has been subjected to a radial force that forces its disalignment except that the tangential force that is activated its rotation.So frictional resistance increases, the sensitivity of water meter is not high; Support to the wing wheel wheel shaft also causes uneven wear, and wearing and tearing its sensitivity of back further descends again.For example: existing DN15 water meter, when 8L/h is following, just can not rotate substantially, that is to say the pipeline behind the table or the race of water swivel, emit, to drip, leakage can't be measured, and water resource is run off in vain.
Summary of the invention
The objective of the invention is, improve the wear-resisting condition between wing wheel and its bolster in water meter measurement performance and the measuring mechanism, the sensitivity that improves water meter prolongs its serviceable life.
Realize the water meter of a kind of wing wheel band of described purpose fairing, it mainly is made up of measuring mechanism (4), indicating mechanism (3), shell (5), cover (2) etc.Its improvement part is characterised in that in the measuring mechanism (4) of table rectification wing wheel (7) is housed.
Measurement chamber (6) is arranged at its top of measuring mechanism (4), measuring top, chamber (6) has water delivering orifice (61), and the bottom of measuring chamber (6) be that the pod apertures (63) that center, uniform several current of annular are guided rectification wing wheel (7) into communicates with measurement chamber (6) with bolster (65).The other end of these pod apertures (63) communicates with a collecting chamber (83), and the water inlet (82) of this collecting chamber (83) is in collecting chamber (83) bottom, and coaxial with described rectification wing wheel (7).Covered a check disk (10) on the water inlet (82) in collecting chamber (83), outside the periphery of this check disk (10) to six vertical uniform gussets (81) of its guiding; That is to say, this check disk (10) can be along gusset (81) slippage up and down, and, on the circumferential side wall of measuring chamber (6), have several uniform, its position than measure chamber (6) water delivering orifice (61) low, than the high shunting aperture (62) of current being guided into rectification wing wheel (7) vanelets (73) of pod apertures (63).The other end of this shunting aperture (62) all communicates with bowl-type filter screen (9) with described collecting chamber (83) water inlet (82).
The technology of the present invention improved plan is, the rectification wing wheel (7) of measuring dress in the chamber (6) is useful on the annulus (74) of rectification, several big blades (72) are arranged in the annulus (74), the face that big blade (72) is hit is the inclined-plane, the angle of this inclined-plane and wing wheel wheel between centers is 10 °～60 °, this angle has this rectification wing wheel (7) generation axial thrust load upwards, on annulus (74) outer shroud several vanelets (73) are arranged, the face that vanelets (73) is hit is the plane, disclose so far, those skilled in the art can find out fully: the described big blade (72) of water impact rectification wing wheel (7) that attracts from side amount chamber (6) bottom pod apertures (63) is the inclined-plane, drive the direction rotation of rectification wing wheel (7) towards needs, that is to say, the big current that attract from pod apertures (63) remove the same with prior art, impact blade and make the wing wheel rotation (obviously, this is main) outside, also have an axial thrust load that the rectification wing wheel is up pushed away, the friction between the bearing of measuring interior bolster (65) in chamber (6) and rectification wing wheel (7) is reduced.
Now in conjunction with the actual measurement process of technical scheme of the present invention in water meter, introduce its superiority: when the water yield of normal use flows to the water inlet (82) of collecting chamber (83), because the pressure of current is enough big, cover in the check disk (10) on this water inlet (82) top and upwards backed down, because collecting chamber (83) water inlet (82) is coaxial with rectification wing wheel (7), and pod apertures (63) is that center annular is uniform with rectification wing wheel (7) wheel shaft, so, enter measurement chamber (6) by pod apertures (63), the resultant radial force that impacts the current of the big blade (72) of rectification wing wheel (7) is zero.In other words, what drive rectification wing wheel (7) rotation is pure couple, does not have the sort of radial force that makes wing wheel wheel shaft disalignment of the prior art.Further, the big blade (72) of current on impacting rectification wing wheel (7) that attracts from pod apertures (63) makes its rotation, also has an axial thrust load that rectification wing wheel (7) is up pushed away.Like this, the normal pressure between rectification wing wheel (7) bearing and its lower support axle (65) opposing end faces has just reduced greatly, and friction force has therebetween also reduced naturally widely.The result of comprehensive above-mentioned effect is, in all processes of measuring the water yield, the friction force between rectification wing wheel (7) bearing and its lower support axle (65) reduces, and it is also little that it and rectification wing wheel (7) are taken turns the frictional resistance of between centers.So the present invention has just had the wearing quality more much higher than existing water meter.When the water yield is little to can not back down check disk (10) time, all current just flow to from shunting aperture (62), water slug rectification wing wheel (7) vanelets (73) that attracts by shunting aperture (62).Because the flow area of this shunting aperture (62) is little, measure chamber (6) wall and rectification wing wheel (7) annulus (74) in addition and form little runner, so, when current therefrom pass through, dynamic pressure increases to some extent, can impact rectification wing wheel (7) rotation again, and the less water yield is measured, play the effect of shunting metering, when tiny flow quantity, still have fabulous sensitivity.Especially under the situation that normally makes water consumption, rectification wing wheel (7) bearing and bolster (65) wearing and tearing are very little, so prolonged its serviceable life.
