Water meter device with water hammer resisting structure

Abstract

The invention relates to the technical field of water meter devices, in particular to a water meter device with a water hammer resisting structure, which comprises a water meter device main body. Thewater meter device main body comprises a water meter shell, a water inlet pipe is fixedly arranged at one end of the water meter shell, a water outlet pipe is fixedly arranged at the other end of thewater meter shell, and water hammer eliminating mechanisms are inserted into the top ends of the water inlet pipe and the water outlet pipe in a threaded mode. By arranging the water hammer eliminating mechanism, the movable piston moves up and down under the dual effects of gas with certain pressure and irregular water hammer to form a dynamic balance, so that irregular water hammer wave oscillation is effectively eliminated, water flow shock waves can be secondarily eliminated through the water hammer eliminating mechanism, water flow impact waves can be eliminated in the shortest time, so that pipelines in the water inlet pipe and the water outlet pipe are protected, the pipelines are prevented from being broken, water flow is prevented from rapidly impacting mechanical parts in the water meter shell, and the service life of the device is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of water meter devices, in particular to a water meter device with an anti-water hammer structure. Background technique [0002] With the development of technology, more and more smart water meters have entered thousands of households. Water meters are instruments for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into volumetric water meters and speed water meters. Originated in the United Kingdom, the development of water meters has a history of nearly 200 years. When selecting the specifications of a water meter, you should first estimate the size and flow range of the flow normally used, and then choose a water meter with a specification that is closest to the value of the commonly used flow. as preferred. A water meter is an instrument for measuring water flow and records the water consumption of tap water. The water meter is installed on the water p...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a water meter device with an anti-water hammer structure to solve the problem of the water pipe on the side of the water meter due to pressure water flow when the user suddenly loses power or the valve is closed too quickly in the existing water meter device proposed in the above background technology. Inertia produces water flow shock waves, and the force generated by the water flow shock waves back and forth will quickly impact the internal mechanical structure of the water meter, which is easy to damage the internal fixed structure of the pipeline and water meter, thus affecting the accuracy of detection
