Description

Technical Field

[0001] The invention belongs to the field of urban pipe network water supply and relates to a non-contact metering valve control system. Background Art

[0002] In the last century and early 21st century, urban water supply networks were primarily constructed from cast iron and galvanized pipes. These pipes are susceptible to corrosion and scaling, leading to increased impurities and poor water quality. Due to factors such as not reaching their designed service life and high replacement costs, urban water supply networks in older urban areas were generally not replaced promptly. During the network upgrade of urban water supply networks in older urban areas, it was discovered that smart water meters and smart valves were experiencing reduced lifespans and high failure rates. Investigations revealed that the cause was poor water quality, which led to rapid scaling on the internal components of the equipment, preventing the smart valves from fully opening or closing. Therefore, there was an urgent need to develop a contactless metering valve control device to measure and control the water supply. Summary of the Invention

[0003] In order to solve the problem of short service life of the above-mentioned water meters and water valves in old water supply pipe networks, the present invention provides a non-contact metering valve control device.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a non-contact metering valve control system, including a main pipeline, the main pipeline is connected to a plurality of water supply pipes, the water supply pipes are installed with a pipe-holding metering device near the main pipeline, and an intelligent pinch valve is installed on the side of the water supply pipe away from the main pipeline of the pipe-holding metering device.

[0005] Preferably, both ends of the intelligent pinch valve are threadedly connected to the water supply pipe.

[0006] Preferably, a plastic hose for water supply and circulation is provided in the smart pinch valve.

[0007] Preferably, the tube-holding metering device and the intelligent tube-pinching valve are electrically connected to a memory.

[0008] Preferably, the memory is electrically connected to a display.

[0009] Preferably, a wireless communication module is provided in the display.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are:

[0011] The pipe-holding metering device of the present invention consists of a pipe clamp and an ultrasonic water meter. The ultrasonic water meter does not come into direct contact with the water flow, thus preventing rust and scaling. The intelligent pinch valve, on the other hand, uses air pressure or a pressure rod to clamp or release the flowing hose, restoring or shutting off the water supply. Furthermore, the pressure rod and other metal components are kept out of contact with the water flow, thus preventing rust and scaling. Therefore, the pipe-holding metering device and intelligent pinch valve of the present invention have a longer lifespan and are not damaged by rust or scaling. Furthermore, the absence of cast iron parts in contact with the water flow reduces water contamination.

[0012] The present invention can perform remote monitoring and control, making water fee billing, water supply restoration, and water supply cutoff more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
