物理除锈

Physical rust removal

使用钢丝刷或砂纸：对于生锈不严重的阀门，可以用钢丝刷或砂纸轻轻擦拭生锈部位，将锈层去除。操作时要注意力度，避免刮伤阀门表面，影响其密封性和外观。

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.

采用喷砂处理：如果阀门生锈面积较大或锈层较厚，可以采用喷砂的方法。利用高速喷射的砂粒冲击生锈表面，去除锈迹和杂质。喷砂处理能快速有效地除锈，且能使阀门表面形成一定的粗糙度，有利于后续的防腐处理。但喷砂处理需要专业设备，一般适用于工业场合。

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.

化学除锈

Chemical rust removal

使用除锈剂：可选用专门的金属除锈剂。将除锈剂喷涂或涂抹在生锈的阀门表面，让除锈剂与锈层充分反应，溶解锈迹。一段时间后，用清水冲洗或用布擦拭干净。使用除锈剂时，要按照产品说明书的要求进行操作，注意安全防护，避免除锈剂接触皮肤和眼睛。

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：对于一些小型阀门或生锈严重的部件，可以将其放入稀酸溶液中浸泡除锈。常用的酸液有盐酸、硫酸等，但酸液浓度不宜过高，浸泡时间要适当控制，以免过度腐蚀阀门。浸泡后，需用清水彻底冲洗干净，并及时进行中和处理和干燥，防止再次生锈。

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.

防锈处理

涂抹防锈油：除锈后，为防止阀门再次生锈，可在其表面涂抹一层防锈油。防锈油能在阀门表面形成一层保护膜，隔绝空气和水分，阻止铁锈生成。涂抹时要确保油层均匀，覆盖所有容易生锈的部位。

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.

喷涂防腐漆：对于一些对外观要求较高或在恶劣环境中使用的阀门，可以选择喷涂防腐漆。在除锈和表面处理后，按照规定的工艺进行喷漆操作。防腐漆具有良好的耐腐蚀性和装饰性，能有效延长阀门的使用寿命。

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.

日常维护

Routine maintenance

定期检查：建立定期检查制度，经常观察阀门的外观和使用情况，及时发现早期生锈迹象，以便采取相应措施，防止锈迹扩大。

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.

保持清洁干燥：保持阀门表面清洁，及时清除灰尘、污垢和水渍。对于在潮湿环境中使用的阀门，要加强通风或采取防潮措施，尽量减少阀门与水分接触的机会。

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.

合理使用和保养：按照阀门的使用说明书正确操作，避免阀门受到不必要的碰撞和损伤。在阀门的活动部位，如阀杆、螺母等，定期涂抹润滑剂，保证其灵活转动，防止因摩擦而生锈。

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.
