How to clean the fire valve stem and valve body inner wall?

The fire valve stem and the inner wall of the valve body are very important parts of the fire equipment, which play a crucial role in controlling and scheduling the fire water source. During long-term use, due to factors such as water quality and environment, dirt and lime can easily form on the inner walls of the fire valve stem and valve body, which can lead to issues such as lax valve closure and insensitive operation. Therefore, it is particularly important to clean and maintain the inner walls of the fire valve stem and valve body.

一、 Clean the fire valve stem

1. Prepare tools and materials

The tools and materials required to clean the fire valve stem include rubber gloves, brushes, laundry detergent, soapy water, and cleaning fluid.

2. Dismantling the fire valve

Disassemble the fire valve and remove it in the order of the nominal diameter (DN). Pay attention to the usage of the valve and avoid any safety hazards. Place the snap ring and two-way valve on top of the valve aside for backup.

3. Clean the fire valve stem

Soak the valve stem inside the fire valve in soapy water for a few minutes, then gently scrub with a brush to remove all stains and lime adhering to the surface of the valve stem, and then clean with cleaning solution.

4. Apply lubricating oil

Use a brush to evenly apply an appropriate amount of lubricating oil to the surface of the valve stem, without excessive use to avoid affecting the operation effect of the valve.

5. Install fire valves

Assemble the cleaned valve stem and valve components in the corresponding order, pay attention to the correct installation of the valve status, and strictly require that the distance and connection form of the valve meet the actual needs.

二、 Clean the inner wall of the valve body

1. Prepare tools and materials

The tools and materials required to clean the inner wall of the valve body include: car press, brush, aluminum paste, etc.

2. Dismantling the fire valve

Just like cleaning the valve stem, disassemble the fire valve and place all its components aside for future use.

3. Clean the inner wall of the valve body

Touch the inner wall of the valve body once with your hand, wipe off any dirt that can be touched, and then use a press to press out the dirt from the inner body until all the dirt is removed. Then wipe the wall surface with aluminum paste to remove any dirt residue, and thoroughly rinse the wall surface with clean water.

4. Apply lubricating oil

The process of applying lubricating oil is the same as above, and for some small components, the same method can also be used for application.

5. Install fire valves

Assemble the cleaned components and pay attention to the installation position and connection method of the valve to ensure that it can be used normally after installation.

Summary: Cleaning the fire valve stem and inner wall of the valve body is an indispensable process in the maintenance of fire equipment. Only in this way can the normal operation of fire equipment be ensured and the occurrence of disasters be reduced. During the cleaning process, we should not only pay attention to safety issues, but also pay attention to the maintenance and upkeep of the fire-fighting equipment itself. Only in this way can the reliability and durability of firefighting equipment be ensured, thereby contributing to humanized services.
