物理除銹

Physical rust removal

使用鋼絲刷或砂紙：對(duì)于生銹不嚴(yán)重的閥門，可以用鋼絲刷或砂紙輕輕擦拭生銹部位，將銹層去除。操作時(shí)要注意力度，避免刮傷閥門表面，影響其密封性和外觀。

Use a wire brush or sandpaper: For valves that are not severely rusted, gently wipe the rusted area with a wire brush or sandpaper to remove the rust layer. Attention should be paid to the force during operation to avoid scratching the surface of the valve, which may affect its sealing and appearance.

采用噴砂處理：如果閥門生銹面積較大或銹層較厚，可以采用噴砂的方法。利用高速噴射的砂粒沖擊生銹表面，去除銹跡和雜質(zhì)。噴砂處理能快速有效地除銹，且能使閥門表面形成一定的粗糙度，有利于后續(xù)的防腐處理。但噴砂處理需要專業(yè)設(shè)備，一般適用于工業(yè)場(chǎng)合。

Sandblasting treatment: If the rust area or rust layer of the valve is large, sandblasting can be used. Use high-speed sand particles to impact rusted surfaces and remove rust and impurities. Sandblasting treatment can quickly and effectively remove rust, and can create a certain roughness on the surface of the valve, which is beneficial for subsequent anti-corrosion treatment. But sandblasting requires professional equipment and is generally suitable for industrial applications.

化學(xué)除銹

Chemical rust removal

使用除銹劑：可選用專門的金屬除銹劑。將除銹劑噴涂或涂抹在生銹的閥門表面，讓除銹劑與銹層充分反應(yīng)，溶解銹跡。一段時(shí)間后，用清水沖洗或用布擦拭干凈。使用除銹劑時(shí)，要按照產(chǎn)品說(shuō)明書的要求進(jìn)行操作，注意安全防護(hù)，避免除銹劑接觸皮膚和眼睛。

Use rust remover: Specialized metal rust remover can be selected. Spray or apply rust remover onto the rusted surface of the valve, allowing the rust remover to fully react with the rust layer and dissolve the rust. After a period of time, rinse with clean water or wipe clean with a cloth. When using rust remover, follow the requirements of the product manual, pay attention to safety protection, and avoid contact with skin and eyes.

利用酸液浸泡：對(duì)于一些小型閥門或生銹嚴(yán)重的部件，可以將其放入稀酸溶液中浸泡除銹。常用的酸液有鹽酸、硫酸等，但酸液濃度不宜過(guò)高，浸泡時(shí)間要適當(dāng)控制，以免過(guò)度腐蝕閥門。浸泡后，需用清水徹底沖洗干凈，并及時(shí)進(jìn)行中和處理和干燥，防止再次生銹。

Soak in acid solution: For some small valves or severely rusted components, they can be immersed in a dilute acid solution to remove rust. Commonly used acid solutions include hydrochloric acid, sulfuric acid, etc., but the concentration of the acid solution should not be too high, and the soaking time should be appropriately controlled to avoid excessive corrosion of the valve. After soaking, rinse thoroughly with clean water and promptly neutralize and dry to prevent rusting again.

防銹處理

涂抹防銹油：除銹后，為防止閥門再次生銹，可在其表面涂抹一層防銹油。防銹油能在閥門表面形成一層保護(hù)膜，隔絕空氣和水分，阻止鐵銹生成。涂抹時(shí)要確保油層均勻，覆蓋所有容易生銹的部位。

Apply anti rust oil: After rust removal, to prevent the valve from rusting again, a layer of anti rust oil can be applied to its surface. Rust proof oil can form a protective film on the surface of the valve, isolating air and moisture and preventing rust formation. When applying, ensure that the oil layer is uniform and covers all areas that are prone to rusting.

噴涂防腐漆：對(duì)于一些對(duì)外觀要求較高或在惡劣環(huán)境中使用的閥門，可以選擇噴涂防腐漆。在除銹和表面處理后，按照規(guī)定的工藝進(jìn)行噴漆操作。防腐漆具有良好的耐腐蝕性和裝飾性，能有效延長(zhǎng)閥門的使用壽命。

Spray anti-corrosion paint: For valves that require high appearance or are used in harsh environments, spray anti-corrosion paint can be chosen. After rust removal and surface treatment, spray paint according to the prescribed process. Anti corrosion paint has good corrosion resistance and decorative properties, which can effectively extend the service life of valves.

日常維護(hù)

Routine maintenance

定期檢查：建立定期檢查制度，經(jīng)常觀察閥門的外觀和使用情況，及時(shí)發(fā)現(xiàn)早期生銹跡象，以便采取相應(yīng)措施，防止銹跡擴(kuò)大。

Regular inspection: Establish a regular inspection system, regularly observe the appearance and usage of valves, promptly detect early signs of rust, and take corresponding measures to prevent rust from expanding.

保持清潔干燥：保持閥門表面清潔，及時(shí)清除灰塵、污垢和水漬。對(duì)于在潮濕環(huán)境中使用的閥門，要加強(qiáng)通風(fēng)或采取防潮措施，盡量減少閥門與水分接觸的機(jī)會(huì)。

Keep clean and dry: Keep the valve surface clean and promptly remove dust, dirt, and water stains. For valves used in humid environments, ventilation should be strengthened or moisture-proof measures should be taken to minimize the chance of contact between the valve and moisture.

合理使用和保養(yǎng)：按照閥門的使用說(shuō)明書正確操作，避免閥門受到不必要的碰撞和損傷。在閥門的活動(dòng)部位，如閥桿、螺母等，定期涂抹潤(rùn)滑劑，保證其靈活轉(zhuǎn)動(dòng)，防止因摩擦而生銹。

Reasonable use and maintenance: Operate the valve correctly according to the user manual to avoid unnecessary collisions and damage to the valve. Regularly apply lubricant to the active parts of the valve, such as the valve stem and nut, to ensure its flexible rotation and prevent rusting due to friction.
