I. Core Structural Features (with illustrations)
- Flange Connection Structure ：The valve body uses flange connection at both ends. The flange dimensions and sealing surfaces comply with the requirements of GB/T 9119, ensuring the sealing and interchangeability of the pipeline system connections and compatibility with various national standard pipeline systems.
- Main Material and Process ：The valve body is made of **ductile iron (QT450-10)** casting (in accordance with GB/T 12227), with high structural strength, pressure resistance, and impact resistance, suitable for high-pressure conditions such as fire protection and water supply.
- Sensing and Display Unit ：Integrated on top is an electronic display and control module equipped with an LCD screen and operation buttons, displaying flow data in real time; sensor interfaces are provided on the side (wiring terminals and sensor installation structure are shown in the picture), and the sensors use a plug-in design for sensitive response, meeting the requirements of GB/T 32246 for the installation and signal transmission of sensing elements.
- Sealing Design ：The valve body and flange connection use a nitrile rubber sealing gasket (in accordance with GB/T 3452.1), combined with bolt fastening, to ensure zero leakage of the medium and meet the sealing performance requirements of GB/T 13927.

V. Typical Application Scenarios
- Fire protection engineering In automatic sprinkler fire extinguishing systems, it monitors the water flow status of the pipe network and triggers a signal to start the fire pump in case of fire, complying with the "GB 50974 Technical Specifications for Fire Water Supply and Fire Hydrant Systems".
- Water Supply and Drainage Engineering In urban water supply and drainage pipe network, it monitors and controls the flow rate, adapting to the metering scenarios of "GB 50015 Design Standard for Building Water Supply and Drainage".
- Heating System It detects the flow rate of the hot water circulation pipe network to prevent interruption/overflow, meeting the monitoring requirements of "GB 50736 Design Code for Heating, Ventilation and Air Conditioning of Civil Buildings".
- Wastewater Treatment It controls the inflow of the wastewater treatment plant process sections (aeration tank, sedimentation tank), complying with "GB 50334 Acceptance Standard for Engineering Quality of Urban Wastewater Treatment Plants".
- Chemical Pipeline It provides flow alarm and control for low-corrosive liquids (such as clear water raw materials), adapting to the safety monitoring of "GB 50160 Fire Prevention Design Standard for Petrochemical Enterprises".
