燃?xì)忾y門作為燃?xì)庀到y(tǒng)的關(guān)鍵部件，其安全規(guī)范貫穿選型、安裝、使用、維護(hù)及應(yīng)急處理全過程，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.

　　選型需符合國家標(biāo)準(zhǔn)，具備質(zhì)量證明。根據(jù)燃?xì)忸愋瓦x適配閥門，如天然氣閥門注重耐腐蝕性，液化石油氣閥門強(qiáng)調(diào)耐壓性，且規(guī)格需與管道匹配。優(yōu)先選擇操作簡(jiǎn)便、可靠性高的產(chǎn)品，杜絕劣質(zhì)型號(hào)。

　　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.

　　安裝前檢查閥門外觀，確保無損壞。安裝位置選通風(fēng)好、遠(yuǎn)離火源處，連接要牢固，用合規(guī)密封材料。螺紋連接涂專用密封膠，法蘭連接均勻緊固螺栓。安裝后必須做氣密性試驗(yàn)，確認(rèn)無泄漏方可使用。

　　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.

　　使用時(shí)要熟悉操作方法，開關(guān)狀態(tài)清晰。養(yǎng)成 “人走閥關(guān)” 習(xí)慣，長(zhǎng)時(shí)間離開或夜間需關(guān)總閥。常用閥門定期查開關(guān)靈活性，聞到異味立即關(guān)閥、通風(fēng)，禁動(dòng)電器和明火，待安全后排查或求助。閥門附近不堆雜物，防碰撞損壞。

　　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.

　　維護(hù)需定期檢查外觀和密封性，看有無銹蝕、滲漏。長(zhǎng)期未用的閥門要定期啟閉防卡澀，用干布清潔，禁用水洗。閥門故障時(shí)，嚴(yán)禁私拆，找專業(yè)人員檢修。使用 8-10 年的閥門，即使完好也建議更換，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.

　　應(yīng)急處理要果斷：發(fā)現(xiàn)泄漏立即關(guān)上游總閥，開窗通風(fēng)，禁動(dòng)易產(chǎn)生火花的設(shè)備。泄漏量大難控制時(shí)，迅速撤離到安全區(qū)求助?；馂?zāi)涉及閥門時(shí)，確保安全后關(guān)總閥，用滅火器材控火，防閥門變形加劇泄漏。

　　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?xì)忾y門安全規(guī)范關(guān)乎用戶安全，每個(gè)環(huán)節(jié)都不可疏忽，嚴(yán)格遵守才能保障系統(tǒng)穩(wěn)定運(yùn)行，筑牢安全防線。

　　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.
