Abstract
本实用新型涉及一种高灵敏度的冷水水表，水表采用全部侧面进水方式，从而提高了流速，加大了对叶轮的推力；改变水表头三位齿轮传动的传动比来调整计数机构的转速，确保水表的准确性，水表齿轮盒底部设置调节板用它来调节进水阻力的大小来调整叶轮的转动速度以达到调节水表指针快慢的目的。其优点是：水表灵敏度高，准确性和可靠性强，在6升/小时非常微小的流量下也能计量，维护了供水单位和居民利益，有利于节约用水，节约了能量。
The utility model relates to a high-sensitivity cold water meter. The water meter adopts the water inlet mode of all sides, thereby increasing the flow velocity and increasing the thrust to the impeller; changing the transmission ratio of the three-position gear transmission of the water meter head to adjust the speed of the counting mechanism, To ensure the accuracy of the water meter, an adjustment plate is set at the bottom of the water meter gear box to adjust the size of the water inlet resistance to adjust the rotation speed of the impeller to achieve the purpose of adjusting the speed of the water meter pointer. Its advantages are: the water meter has high sensitivity, high accuracy and reliability, and can measure at a very small flow rate of 6 liters per hour, which protects the interests of water supply units and residents, and is conducive to saving water and energy.
Description
Technical field:
The utility model belongs to a kind of cold-water meter and particularly relates to a kind of highly sensitive cold-water meter.
Background technology:
The cold water meter that present known water supply industry uses mostly is A level water meter, the water inlet of water meter is based on lateral inflow, be aided with bottom water inlet, regulate water velocity by being fixed on impeller box bottom adjustable plate, these current promote wheel rotation and the driven gear counting mechanism reaches the metering purpose.But A level water meter exists stoichiometric level and the low defective of sensitivity, and causes water meter not to be measured under tiny flow quantity, and the long-term accuracy that can influence water meter measurement of using causes enormous economic loss to water-supplying unit, also is unfavorable for using water wisely.
Summary of the invention:
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: water meter is by lateral inflow, and three gear-driven ratio of gear of change water meter head, the adjustable plate of water meter is arranged on the gearcase bottom simultaneously, connect with gearcase with screw, gear material adopts anti-abrasive material.
The utility model can also adopt following technical measures: three gear-driven ratio of gear of described water meter head (gear ratio) are: when water meter nominal bore is 15mm and 20mm, and first: 25: 10, second: 30: 9, the 3rd: 31: 9.
Advantage and the good effect that the utlity model has are: increased substantially the sensitivity of water meter, guarantee under very small flow, also can measure, the accuracy height of water meter, reasonable price, this water meter is used to the meterage of registering one's residence, it measures accurate, good reliability, has safeguarded water-supplying unit and numerous residents' interests, has reduced the water rate of losing of water-supplying unit, help using water wisely, saved the energy.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cut-open view of Fig. 1.
Fig. 3 is that the gear drive of gear number system launches synoptic diagram.
Fig. 4 is adjustable plate synoptic diagram and B-B cut-open view.
Embodiment:
For further understanding summary of the invention of the present utility model, characteristics and effect, now exemplify following examples and conjunction with figs. is described in detail as follows, see also Fig. 1, Fig. 2, Fig. 3, Fig. 4, water meter is all by 2 water inlets of lateral inflow mouth, improved water velocity and strengthened the thrust of water impeller 1, impeller 1 rotates under the promotion of waterpower, adjustable plate 3 is fixed on the bottom of gearcase 5 with adjusting screw 4, when rotating adjusting screw 4, adjustable plate 3 rotates thereupon, and the change of its direction can be adjusted the resistance size that enters impeller 1 current, thereby the velocity of rotation of control impeller 1, simultaneously, the velocity of rotation of gear 6 also can respective change, for make by on the impeller 1 during one ton of water the gear counting mechanism also should show the one ton of water of passing by, just must change three gear-driven ratio of gear in the water meter gear counting mechanism, guarantee the accuracy of measuring with the velocity of rotation of adjusting counting mechanism.Now commonly used and maximum water meter nominal bore 15mm of usefulness and the water meter of 20mm are example with scape, first 9 gear ratio of three gear ratios (ratio of the gear number of teeth) are 25: 10 in the gear counting mechanism, second 10 gear ratio is 30: 9, and the 3rd 11 gear ratios are 31: 9.Gear material is selected anti abrasive polyoxymethylene for use.The initiating flow of this high sensitivity water meter (rise/hour) 15mm water meter is reduced to 7 by 10, and the 20mm water meter is reduced to 7 by 14, i.e. sensitivity improves greatly, accurate measurement, good reliability, and cost is low, helps using water wisely, has promptly saved the energy.
