I. Core Structural Features
- Connection Type : Uses Flange Connection The flange dimensions and sealing surface conform to GB/T 9119 "Steel Plate Welding Flanges for Pipes", ensuring the sealing and interchangeability of the pipeline system installation.
- Structural Form : Visible stem wedge single gate plate structure (as shown in the figure, the handwheel drives the valve stem up and down, and the gate plate is wedge-shaped), conforming to GB/T 12234 "Steel Gate Valves for Petroleum, Petrochemical and Related Industries", the wedge gate plate can self-adapt to temperature difference deformation, ensuring reliable sealing.
- Sealing Design : The valve seat and gate sealing surface use Hard Alloy Overlay Welding (indicated by "H" in the model number), conforming to GB/T 12234's technical requirements for sealing surface overlay welding, excellent wear resistance, suitable for frequent opening and closing or conditions with particulate media.
- Drive Type : Manual drive (handwheel operation), the closing torque conforms to GB/T 26480 "Inspection and Testing of Valves", convenient operation and suitable for scenes without power source.
