Why should the fire extinguisher valve be cleaned and pre-treated before installation

Fire extinguisher valves play a vital role in fire extinguishing systems, and the stability of their performance directly affects the reliability and safety of the entire system. Therefore, it is particularly important to carry out comprehensive cleaning and pretreatment before installing the valve. This process can not only extend the service life of the valve and its related components, but also significantly improve the efficiency of fire extinguishing.
Importance of cleaning and pretreatment
Before installing the fire extinguisher valve, cleaning and pretreatment are key measures to ensure the stable performance of the valve and its connecting parts. The cleaning process can effectively remove impurities such as oil, dust, rust, etc. on the valve and its connecting parts. If these impurities are not removed in time, they may have a negative impact on the sealing performance of the valve, resulting in leakage or the valve cannot be opened and closed normally. Pretreatment includes applying lubricants and rust inhibitors, etc., which are aimed at reducing the friction resistance of the valve during operation, preventing corrosion and rust, and thus improving the reliability and durability of the valve.
Specific content of cleaning work
Appearance cleaning: Use a clean cloth or brush to remove oil and dust from the valve and its connecting parts. For stains that are difficult to remove, it is recommended to use appropriate detergents for treatment, but avoid using chemicals that are corrosive to the valve material.
Internal cleaning: For valves that require internal cleaning, such as valves with filters or internal channels, special cleaning tools or equipment must be used to ensure that the internal channels are unobstructed to prevent blockage or affect the flow of fire extinguishing agents.
Sealing surface inspection: During the cleaning process, special attention should be paid to the sealing surface of the valve to ensure that it is free of damage, scratches, and rust. If damage or rust is found, the relevant parts should be repaired or replaced in time.
Specific content of pretreatment work
Lubricant application: After cleaning, an appropriate amount of lubricant should be applied to key parts such as the operating mechanism and sealing surface of the valve to reduce friction resistance during operation, thereby improving the operating flexibility and sealing performance of the valve.
Anti-rust treatment: For valve parts that are prone to rust, such as bolts and nuts, anti-rust treatment should be carried out. Special anti-rust agents can be used for spraying or soaking to form a protective film to prevent parts from rusting.
Inspection and adjustment: During the pretreatment process, it is also necessary to check whether the operating mechanism of the valve is flexible and reliable and whether the sealing performance is good. If problems are found, they should be adjusted or replaced in time to ensure that the valve can work normally after installation.
Precautions for cleaning and pretreatment
Safety is always the top priority when performing cleaning and pretreatment work. Relevant safety operating procedures should be strictly followed to prevent accidents. In addition, choosing the right tools and materials is also crucial. According to the material and type of the valve, the cleaning agent and pretreatment agent should be reasonably selected to avoid damage to the valve. Finally, after cleaning and pretreatment, be sure to conduct a comprehensive inspection of the valve to ensure that all parts meet the relevant requirements and that there are no omissions or omissions.
