Description
Technical Field
The invention belongs to the technical field of water meters, and relates to a water meter core adjusting device.
Background
The water meter is a meter for measuring water flow, and most of the water meters are integrated flow measurement of water, and generally are divided into two types, namely a volumetric water meter and a speed water meter. The speed type water meter comprises a horizontal spiral vane type water meter suitable for a large-caliber pipeline, and comprises a meter shell, an error adjusting device, an impeller, a worm gear mechanism, a dial plate, a bracket with a water inlet and a water outlet and a flange cover of a positioning bracket, wherein the impeller is arranged on the bracket to form a water meter core, the bracket is positioned in the meter shell, the flange cover is connected with the meter shell, and the flange cover is positioned between the dial plate and the meter shell. When the horizontal spiral vane type water meter is applied, the impeller axis of the water meter is generally parallel or coincident with the axis of a tap water pipeline, and the impeller adopts a spiral vane shape. When water flows into the water meter, the water flows out after impacting the impeller to rotate along the axial direction of the impeller, the rotating speed of the impeller is in direct proportion to the water flow speed, the water is transmitted through the worm and gear mechanism, and the total water passing through the meter case is displayed on the counting mechanism. Therefore, the stable rotation of the impeller has a great relationship with the measuring range, sensitivity, precision and circulation capacity of the water meter.
When the flow of water is too large, the overload water can impact the impeller, so that the overload water is prevented from impacting the impeller as much as possible, and the excessive water flowing through the water flowing through port is additionally formed in the shell, which is easy to think by a person skilled in the art, however, the movement body is positioned in the watchcase, so that when the size of the adjusting port is required to be adjusted, the movement body needs to be detached from the watchcase, and the problem of poor adjustment convenience exists in the water meter. Meanwhile, the arrangement of the adjusting port influences the circulation balance of the impeller, namely the flow quantity of water flow at the position of the impeller close to the adjusting port is large, the impact force of the water flow at the position is correspondingly larger, the position of the impeller is easy to deviate under the impact action of the water flow after long-term use, the impact force of the water flow on the impeller is increased, the rotation stability of the impeller is reduced, and the measuring precision of the water meter is reduced.
