I. Core Structural Features
- Connection and Sealing :Left end external thread, right end internal thread, thread conforms to GB/T 7306 55° sealing pipe thread; built-in red nitrile rubber sealing gasket (conforms to GB/T 5574 Industrial vulcanized rubber sheet), forming a double seal with the valve core soft seal (conforms to GB/T 12237 Industrial valves metal sealed ball valves) Double Seal ,Reinforces gas medium airtightness.
- Valve Body Protection :Brass substrate surface electroplating treatment, conforms to GB/T 12225 General valves copper alloy castings technical conditions, improves corrosion resistance in gas and humid environments.
- Operating Mechanism :Red reinforced nylon handle (conforms to GB/T 1040 Plastics Determination of tensile properties), 90° rotation opening and closing, handle and stem anti-detachment design, small operating torque and intuitive opening and closing status (handle parallel/perpendicular to flow direction corresponds to opening and closing).

V. Typical Application Scenarios
- Domestic Gas System :Natural gas, liquefied gas household branch pipes, gas stove/water heater front-end pipeline control (must comply with local gas safety regulations);
- Industrial Gas Transportation :Opening and closing of compressed air, nitrogen, argon and other inert gas pipelines (adaptable to pneumatic equipment, gas station houses);
- Pneumatic Equipment Matching :Gas source switch for pneumatic tools, cylinders and other pneumatic components, convenient for equipment maintenance and gas volume adjustment;
- Laboratory Gas Path :Precise control of gas medium for analytical instruments and experimental devices (small diameter adapts to precise scenarios);
- Small Gas Appliances :Gas supply pipeline for gas boilers and burners (gasket seal enhances airtightness).
