燃气阀门作为燃气系统的关键部件，其安全规范贯穿选型、安装、使用、维护及应急处理全过程，是防范事故的重要保障。

　　As a key component of the gas system, the safety standards of gas valves run through the entire process of selection, installation, use, maintenance, and emergency response, and are an important guarantee for preventing accidents.

　　选型需符合国家标准，具备质量证明。根据燃气类型选适配阀门，如天然气阀门注重耐腐蚀性，液化石油气阀门强调耐压性，且规格需与管道匹配。优先选择操作简便、可靠性高的产品，杜绝劣质型号。

　　The selection must comply with national standards and have quality certification. Select suitable valves based on the type of gas, such as natural gas valves that emphasize corrosion resistance and liquefied petroleum gas valves that emphasize pressure resistance, and the specifications need to match the pipeline. Prioritize products that are easy to operate and highly reliable, and eliminate inferior models.

　　安装前检查阀门外观，确保无损坏。安装位置选通风好、远离火源处，连接要牢固，用合规密封材料。螺纹连接涂专用密封胶，法兰连接均匀紧固螺栓。安装后必须做气密性试验，确认无泄漏方可使用。

　　Check the appearance of the valve before installation to ensure there is no damage. The installation location should be well ventilated, away from fire sources, firmly connected, and sealed with compliant materials. Apply special sealant to threaded connections, and tighten bolts evenly on flange connections. After installation, an air tightness test must be conducted to confirm that there are no leaks before use.

　　使用时要熟悉操作方法，开关状态清晰。养成 “人走阀关” 习惯，长时间离开或夜间需关总阀。常用阀门定期查开关灵活性，闻到异味立即关阀、通风，禁动电器和明火，待安全后排查或求助。阀门附近不堆杂物，防碰撞损坏。

　　Familiarize yourself with the operation method and ensure clear switch status when using. Develop the habit of "closing the valve when people leave", and close the main valve when leaving for a long time or at night. Regularly check the flexibility of commonly used valves. If you smell any odor, immediately close the valve and ventilate. Do not touch electrical appliances or open flames. Wait until it is safe to investigate or seek help. Do not pile up debris near the valve to prevent collision damage.

　　维护需定期检查外观和密封性，看有无锈蚀、渗漏。长期未用的阀门要定期启闭防卡涩，用干布清洁，禁用水洗。阀门故障时，严禁私拆，找专业人员检修。使用 8-10 年的阀门，即使完好也建议更换，避免密封件老化。

　　Regular inspection of appearance and sealing is required for maintenance, to check for rust and leakage. Valves that have not been used for a long time should be opened and closed regularly to prevent jamming, cleaned with a dry cloth, and water washing is prohibited. When the valve malfunctions, it is strictly prohibited to dismantle it privately and seek professional personnel for maintenance. Valves that have been in use for 8-10 years are recommended to be replaced even if they are intact to avoid aging of the seals.

　　应急处理要果断：发现泄漏立即关上游总阀，开窗通风，禁动易产生火花的设备。泄漏量大难控制时，迅速撤离到安全区求助。火灾涉及阀门时，确保安全后关总阀，用灭火器材控火，防阀门变形加剧泄漏。

　　Emergency response should be decisive: if a leak is found, immediately close the upstream main valve, open windows for ventilation, and prohibit the operation of equipment that is prone to sparks. When the leakage is large and difficult to control, quickly evacuate to a safe area for help. When a fire involves valves, ensure safety and close the main valve. Use fire extinguishing equipment to control the fire and prevent valve deformation from exacerbating leakage.

　　燃气阀门安全规范关乎用户安全，每个环节都不可疏忽，严格遵守才能保障系统稳定运行，筑牢安全防线。

　　The safety regulations of gas valves are related to user safety, and every link cannot be neglected. Strict compliance is necessary to ensure the stable operation of the system and build a strong safety defense line.
