Abstract

A drip counting meter belongs to the field of mechanical control. The utility model adds a mechanical control device on the basis of the ordinary water meter. The device is fastened to the lower part of the water meter case by the meter body seat (1), and fits together with the sinking iron (2) to form a control device for the water source of the water meter. In the closed state, when the water flow is small, the water flows through the central conduit (7) to the flat conduit (8) and then flows out from the tapered outlet pipe (9), directly driving the impeller of the water meter to rotate, increasing the sensitivity of the water meter, and completing the drip counting. When the water meter is in normal use, the water flow rushes up the sinking iron (2) and the water flow enters the water meter along the water inlet system of the original water meter to maintain normal measurement. The utility model is simple, reliable and low in cost, and can play a positive role in reducing losses of water supply departments and enhancing people's awareness of water saving.

Description

drip counter

The utility model relates to a water meter, in particular to a high-sensitivity water meter capable of counting when dripping water.

At present, the principle of the mechanical water meter used is that the water flow drives the impeller to rotate, and then drives many gears with different diameters to rotate to achieve counting. One of the problems with this type of water meter is the inability to turn the impeller when there is little water flow. Therefore, it cannot be measured when the water meter drips, and individual people use dripping water to "save" expenses. In order to arouse people's awareness of water conservation and reduce losses in the water supply sector, it is necessary to renovate the existing water meters.

The purpose of the utility model is to provide an improved water meter, which can accurately count when the user drips water.

The technical scheme of the water meter provided by the utility model is as follows: it is basically similar to the structure of the existing water meter, and what is changed is that a device is added to the lower part of the original water meter, as shown in Figure 1: The inner and lower parts of the water meter case fit together with the sinker iron (2) to form a closed state to the water inlet (3) of the meter body (1), when the water flow flows from the central conduit (7) to the flat conduit (8) and then to the cone Type water outlet pipe (9) concentrates into local water pressure, injects the impeller box of water meter, directly promotes impeller to rotate, finishes drip counting.

The working principle of the utility model is: when the water meter is in normal use (nominal flow rate, boundary flow rate, minimum flow rate), the water flow rushes up the sinking iron (2) and the water flows to the water inlet system of the water meter along the periphery of the sinking iron (2), Simultaneously, the middle flow valve (6) rises along the middle hole (4) under the effect of the water flow, and blocks the water flow of the tapered water outlet pipe (9). As shown in Figure 2: it will not affect the accurate counting of the water meter. The upper part of sinking iron (2) is disc-shaped, and the lower part is taper-shaped to match the table body seat (1), and has a certain weight. When there is no water flow or a small amount of water flow in the water meter, due to the self-weight of the sinking iron (2) tightly pressing on the water inlet (3) of the meter body seat (1), a closed state is formed, so that a small amount of water can only flow from the central conduit (7) Flow to the tapered outlet pipe (9). The middle flow valve (6) makes the central conduit (7) align with the flat conduit (8) under the control of the support (5) to ensure the unimpeded flow of small water. The entire device is generally made of brass or stainless steel.

The utility model has the advantage of completing drip counting without changing the basic structure of the original water meter. The utility model has the advantages of simple structure and low cost, and can play a certain role in promoting people's awareness of water saving and reducing losses of water supply departments.
