The smart water meter prevents backflow, so that the water is safe and worry-free

In the course of daily water supply, the flow of water should flow smoothly in a given direction, but in reality there are many factors that lead to counterflows. Sudden fluctuations in water pressure are one of the common causes, such as during peak water consumption periods, when multiple areas use a large amount of water at the same time, which can lead to a local drop in water pressure, and when the water pressure is restored, it is easy to create backflow. Temporary operations during pipeline repairs, such as improper closing and opening of valves, can also cause abnormal reversal of water flow. Equipment failures, such as the abnormal operation of water pumps, can also cause water flow disorders.

The threat to water security from countercurrents is manifold. From the perspective of measurement, the measurement data of traditional water meters will be deviated under the impact of countercurrent. This makes it difficult for water supply enterprises to accurately calculate the actual water consumption of users, leads to disputes over water bill settlement, interferes with the monitoring and analysis of the overall water consumption situation of water supply enterprises, and affects the rational planning and allocation of water resources.

From the perspective of water quality safety, counterflow may carry impurities, bacteria, dirt, etc. from the pipes back to the water supply source. For some old pipes, the rust and sediment accumulated inside will be swept into the water flow when it flows backwards, and then contaminate the entire water supply system. Especially in places with extremely high water quality requirements such as hospitals and food processing enterprises, water pollution caused by reverse flow may directly endanger the health of patients, affect food quality and safety, and cause serious consequences.

In plumbing, the impact force generated by the countercurrent can cause damage to the pipeline connections. Long-term backflow impact, the seal at the pipeline connection is easy to age and loosen, resulting in frequent water leakage. Water leakage causes waste of water resources, and may also cause secondary disasters such as ground collapse and damage to building foundations, increasing maintenance costs and loss of social resources.

At the heart of the KM05-06 Wet Type Semi-Liquid Sealed Multi Jet Silver Painted Iron Body Water Meter's anti-backflow design is its advanced check valve. This check valve acts as a "loyal guard" in the water supply system, guarding the normal direction of the water flow at all times. When the water flow is reversed, the check valve can quickly sense and react, with its unique mechanical structure, quickly close the valve channel, effectively preventing the water flow from flowing in the opposite direction.

The structural design of this check valve has been carefully optimized with a special disc and spring combination. The shape and material of the disc have been tested and refined to ensure a tight fit to the seat under a wide range of water flow conditions, preventing backflow. The springs provide just the right amount of spring, allowing the disc to open smoothly when normal water is passing through and close quickly when reverse flow occurs. This design enables the check valve to operate stably in complex water flow environments and effectively prevent the occurrence of reverse flow phenomenon. Its sensitive sensing mechanism is also a highlight. The check valve can monitor the speed, pressure and other parameters of the water flow in real time, and trigger the closing action immediately once the water flow direction changes are detected. This rapid response capability greatly improves the effect of anti-backflow and ensures the safe and stable operation of the water supply system.

In the domestic water use scenario, the anti-backflow design provides a reliable guarantee for residents' domestic water. Taking high-rise residential communities as an example, due to the large difference in floor height and frequent changes in water pressure, the risk of backflow is relatively high. In a high-rise community, due to the unstable water pressure, there was frequent reverse flow, resulting in water heaters, water purifiers and other wading equipment in some residents' homes were damaged, and the water quality was also polluted to a certain extent. After the installation of the KM05-06 Wet Type Semi-Liquid Sealed Multi Jet Silver Painted Iron Body Water Meter, the anti-backflow design played a key role in effectively avoiding backflow, and residents no longer had to worry about damage to water equipment and water quality issues, giving residents more peace of mind about water use.

In commercial places, such as shopping malls, hotels, etc., there are many water equipment, and the stability of water supply is extremely high. When a large shopping mall did not install a water meter with anti-backflow function, it caused backflow due to pipeline maintenance, resulting in abnormal water pressure in the fire protection system in the shopping mall, and some sprinkler heads had backflow, which almost affected the normal operation of the fire protection system. After the installation of the KM05-06 water meter, the hidden danger of backflow was successfully solved, and the water safety and fire safety of the mall were guaranteed.

Water safety is of paramount importance in healthcare facilities with extremely strict water quality requirements. The operating room, intensive care unit and other areas of the hospital have strict requirements for the purity and hygiene standards of water quality. In the event of a backflow that leads to water pollution, it can lead to serious medical accidents. When upgrading the water supply system, a hospital chose the KM05-06 water meter, whose anti-backflow design effectively prevented the pollution of water quality by backflow, ensured the safety of hospital water, and provided a strong guarantee for the treatment and rehabilitation of patients.
