Abstract
The utility model relates to a water gauge part especially relates to perpendicular helical vane type water meter's part. The utility model relates to a divertor has perpendicular helical vane type water meter of through -hole down, including casing and core, wherein the core mainly include counter, blind flange again, go up the divertor, impeller, divertor down, its technical essential lies in under that the top supporting seat surface design of divertor has 2 the through -hole be no less than of equal circumference angular distribution. The utility model discloses an increase divertor through -hole down, after the water gauge was intake, partial rivers can pass through these apertures, to the certain lift of impeller production, upwards lifted the impeller to reduce apical frictional force of impeller bearing and lower divertor. So both can reduce the beginning kinetic energy of impeller, improve the precision of water gauge, improve the performance of whole table rill, can reduce bearing and last apical wearing and tearing of divertor down again, prolong the life of water gauge.
Description
Technical field
The utility model is a kind of water meter part, particularly relates to the part of vertical Woltmann water meter.
Background technology
As shown in Figure 1, vertical Woltmann water meter mainly comprises housing 1 and movement 2, and wherein movement mainly comprises again counter 21, blind flange 22, upper air deflector 23, impeller 24, lower air deflector 25 etc.Lower air deflector is positioned at water inlet position bottom movement, and impeller is between upper and lower air deflector, top 251 supports of air deflector and top 231 location of upper air deflector are fixed on the lower, under the effect of impeller gravity, lower air deflector top 251 and impeller aloxide bearing 241 friction force large, affect the rill precision of water meter, wheel rotation at present air deflector top 251 and impeller aloxide bearing 241 is is easily worn and torn, and affects the serviceable life of water meter.
Summary of the invention
The utility model object is to overcome the high initiating and short-life shortcoming that existing helical vane type water meter exists, and provides that a kind of precision is higher, the vertical Woltmann water meter of longer service life.
The technical scheme that the utility model adopts is the vertical Woltmann water meter that a kind of lower air deflector has through hole, comprise housing and movement, wherein movement mainly comprises again counter, blind flange, upper air deflector, impeller, lower air deflector, and its technical essential is the through hole being no less than 2 having equal circumference angle to distribute in the top supporting seat surface design of lower air deflector.
The utility model increases several little through hole on the top supporting seat surface of lower air deflector.After water meter water inlet, part current can pass through these apertures, to producing certain lift in the middle part of impeller, upwards lift impeller, to reduce top the produced friction force of impeller aloxide bearing and lower air deflector.So both can reduce the initiating kinetic energy of impeller, and improve the precision of water meter, improve the performance of whole table rill, the top wearing and tearing of bearing and lower air deflector can be reduced again, extend the serviceable life of water meter.
The utility model has the through hole of varying number by water meter bore different designs, and more large through-hole number is more for general bore, as: bore 50 centimetres of water meters, have three through holes.
Bore 80 centimetres of water meters, have four through holes.
The diameter of through hole is 1-4 millimeter.
The utility model is by increasing lower air deflector through hole, and when after water meter water inlet, part current can pass through these apertures, produce certain lift to impeller, upwards lift impeller, to reduce the top friction force of impeller bearing and lower air deflector.So both can reduce the initiating kinetic energy of impeller, and improve the precision of water meter, improve the performance of whole table rill, the upper top wearing and tearing of bearing and lower air deflector can be reduced again, extend the serviceable life of water meter.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing vertical Woltmann water meter
Fig. 2 is structural representation of the present utility model
Wherein: top 24 impellers of air deflector on air deflector 231 on 1 housing 2 movement 21 counter 22 blind flange 23
Top 252 through holes of 241 impeller aloxide bearing 25 times air deflectors, 251 times air deflectors.
Embodiment
Be described in detail the utility model below in conjunction with view, the following examples can make professional and technical personnel more understand the utility model, but do not limit the utility model in any form.
As shown in Figure 2, a kind of lower air deflector has the vertical Woltmann water meter of through hole, comprise housing 1 and movement 2, wherein movement mainly comprises again counter 21, blind flange 22, upper air deflector 23, impeller 24, lower air deflector 25, impeller 24 is between upper and lower air deflector, top 251 supports of air deflector and top 231 location of upper air deflector are fixed on the lower, at the through hole 252 being no less than 2 that the top supporting seat surface design of lower air deflector 25 has equal circumference angle to distribute, the diameter of through hole 252 is 1-4 millimeter.After water meter water inlet, part current can pass through these apertures, to producing certain lift in the middle part of impeller, upwards lift impeller, to reduce the friction force that impeller aloxide bearing 241 and lower air deflector top 251 produce.Reduce the initiating kinetic energy of impeller, improve the precision of water meter, improve the performance of whole table rill, bearing and the top wearing and tearing of lower air deflector can be reduced again, extend the serviceable life of water meter.
Have the through hole of varying number by water meter bore different designs, more large through-hole number is more for bore, and diameter is also larger, as: bore 50 centimetres of water meters, have three through holes 252, and the diameter of through hole 252 is 2 millimeters.Bore 80 centimetres of water meters, have four through holes 252, and the diameter of through hole 252 is 3 millimeters.It is same as the prior art that all the other do not state part.
The above is only preferred implementation of the present utility model, for those skilled in the art, do not depart from make in essential scope of the present utility model improvement, replacement and retouching, also should belong to protection domain of the present utility model.
