The core of the liquid seal technology of Single-jet Series Water Meter is to use the static pressure characteristics of liquid to balance the pressure difference. When the pressure inside the water meter changes due to water flow or other factors, the liquid in the liquid seal will respond quickly and form a stable static pressure layer in the sealing cavity. This static pressure layer is like a barrier that can prevent the internal high-pressure liquid or gas from leaking to the outside through the sealing gap, and also prevent external pollutants or low-pressure gas from entering the water meter, thereby ensuring the sealing and safety of the water meter.
The mechanical structure inside the water meter is complex, with many tiny gaps and pores. These gaps may be difficult to completely seal under normal circumstances, but liquid seal technology can easily cope with them. The liquid is fluid and can automatically fill these tiny gaps to form a continuous, leak-free sealing barrier. This filling action not only improves the sealing effect, but also enhances the overall structural strength of the water meter.
The liquid seal can also effectively isolate the water meter from gas contact with the external environment. In complex environments such as industrial production, pollutants such as external dust and tiny particles can easily enter the water meter, causing problems such as blockage, wear of parts or inaccurate data. Liquid sealing technology blocks these pollutants outside the water meter by forming a layer of liquid barrier, thereby protecting the cleanliness and normal operation of the internal mechanical structure.
Liquid sealing technology plays a significant role in improving the measurement accuracy of water meters. In water meter design, the accuracy of the metering tube is crucial, and the liquid seal can prevent the metering tube from deviating in a static state and errors caused by partial friction. Through liquid sealing technology, the stability and accuracy of the metering tube during the measurement process can be ensured, thereby improving the overall measurement performance of the water meter. This is crucial for application scenarios that require accurate measurement of water flow.
There are many precise mechanical structures inside the water meter, which have high requirements for the working environment. Liquid sealing technology can not only provide a stable lubrication environment, reduce the probability of mechanical wear and failure, but also isolate the impact of external temperature changes on the internal mechanical structure to a certain extent. Through liquid sealing technology, the stability and reliability of the water meter in different environments can be ensured, and its service life can be extended. This is of great significance for water meters that need to operate stably for a long time.
Liquid seal technology can effectively extend the service life of water meters by improving the sealing performance of water meters and protecting the internal mechanical structure. During long-term use, water meters will inevitably be affected by various factors and fail or be damaged. Liquid seal technology can reduce the risk of these failures and damages, ensuring that the water meter can operate continuously and stably. This has significant benefits in reducing maintenance costs and improving usage efficiency.
In Single-jet Series Water Meter, liquid seal technology is usually applied to the sealing cavity between the rotor and the housing. This design enables effective sealing between the rotating and stationary parts to prevent leakage and ingress of the medium. When water flows through the water meter, the rotor rotates to measure the water flow. The liquid seal ensures the sealing between the rotor and the housing, preventing the water from leaking out of the sealing gap. At the same time, the liquid seal can also protect rotating parts such as the rotor from erosion and wear by external contaminants, ensuring its long-term stable operation.
