I. Core Structural Features (with illustrations)
- Flange Connection Design ：The valve body uses National Standard Flange Connection (Compliant with GB/T 9119, Flat and Raised Face Integral Steel Pipe Flanges), the flange sealing surface and bolt hole layout are compatible with the national standard pipeline system, ensuring connection sealing and universality.
- Main Material and Process ：The valve body uses **Ductile Iron (QT450-10)** casting (implementing GB/T 12227, General Valves - Technical Conditions for Carbon Steel Castings), with anti-corrosion spray coating on the surface, pressure-resistant and impact-resistant, suitable for high-pressure conditions such as fire protection and industrial fluids.
- Sensing and Display Integration ：Equipped at the top with Electronic Display Control Unit (including LCD screen and operation buttons), real-time display of flow data; a sensor installation interface is provided on the side (wiring terminals and sensor structure are visible in the picture), the sensor adopts an insertion design, with sensitive response, conforming to the installation and signal transmission requirements of GB/T 32246 Thermal Flow Switches.
- Sealing System Design ：The valve body and flange use Nitrile Rubber Gasket (Compliant with GB/T 3452.1, Hydraulic and Pneumatic O-ring Rubber Seals), combined with bolt fastening structure, ensuring zero leakage of medium, meeting the sealing performance requirements of GB/T 13927, Industrial Valves - Pressure Test.

Traffic switch
The flow switch uses a national standard flange connection (GB/T 9119) and a ductile iron body (GB/T 12227), integrating a high-precision sensor and electronic display unit. The flow monitoring accuracy reaches ±2% FS, and the protection level is IP65. It is suitable for various fields such as fire protection, water supply and drainage, heating, and industrial cooling. It monitors fluid flow in real time and outputs switching signals, providing reliable protection for the safe and efficient operation of the system. It is a national standard compliant core component for industrial and civil pipeline flow control.
