Mechanical screw-wing water meter with a ductile iron body and flange connection. It features accurate and stable measurement, strong anti-interference capability, and is suitable for municipal water supply, industrial production, agricultural irrigation, etc., enabling precise metering of large-flow water and ensuring efficient and reliable water supply management.
Performance
1. Accurate and Stable Measurement: Adopts a screw-wing impeller structure, ensuring uniform water flow impact and effectively reducing mechanical wear. It maintains high metering accuracy within ±2% even after long-term operation, meeting the stringent requirements of industrial and municipal water supply.
2. Strong Anti-interference Capability: The meter body is integrally cast from ductile iron, which is pressure-resistant and corrosion-resistant, and can withstand water hammer impacts and water quality fluctuations in the pipe network. A built-in anti-magnetic interference device prevents external magnetic fields from affecting measurement accuracy.
3. Long Service Life: Key components are made of stainless steel and engineering plastics, which are anti-aging and rust-resistant. It can operate stably for more than 10 years in environments ranging from -20℃ to 60℃, significantly reducing maintenance and replacement costs.
Application
1. Municipal Water Supply Main Lines: Widely used in main lines and branch nodes of urban water supply networks. Large-diameter flange connections are suitable for DN50~DN300 pipe diameters, enabling accurate metering of total water consumption in residential areas, factories, and public buildings, and providing reliable data for water fee accounting and pipe network scheduling.
2. Industrial Production Water: Suitable for production water metering in chemical, power, metallurgical and other industries. It can withstand high-flow and high-pressure working conditions, support bidirectional flow metering, and meet the precise control requirements of industrial circulating water and process water.
3. Agricultural Irrigation and Water Conservancy: In farmland irrigation, water conservancy pump stations and other scenarios, it can adapt to turbid water quality and high-flow impacts. It features an anti-clogging design, effectively metering irrigation water consumption, and supporting agricultural water-saving management and water resource allocation.
Specifications
1. Caliber and Connection Method: Covers various calibers such as DN50, DN80, DN100, DN150, DN200, DN300, and adopts flange connections in compliance with national standards like GB/T 17219. It adapts to water supply networks of different pipe diameters, with convenient installation and strong sealing performance.
2. Flow and Pressure Ratings: The nominal pressure is 1.6MPa, and the overload flow can reach 1.25 times the nominal flow. The common flow range covers Q1~Q4 levels, meeting the full-condition metering requirements from low to high flow and adapting to different water supply scenarios.
3. Material and Protection Level: The meter body is made of ductile iron QT450-10, the cover is stainless steel 304, and the seals are nitrile rubber. The protection level reaches IP65, enabling it to adapt to harsh environments such as humidity and dust, ensuring long-term stable operation.
