Industrial valves are an important accessory for controlling the flow of media on industrial pipelines. They are widely used in petroleum, chemical industry, metallurgy, electric power, paper-making, pharmaceuticals, food and other industries. In order to ensure the normal operation of industrial valves and extend their service life, they need to be maintained regularly. TWS will introduce several common industrial valve maintenance methods below.
I. Regular inspection
Regular inspection of industrial valves is an important part of maintenance. The inspection contents include: whether the appearance of the valve is damaged, corroded, etc.; whether the sealing performance of the valve is good; whether the operation of the valve is flexible; whether the connection parts of the valve are loose, etc. If problems are found, they should be repaired or replaced in time.
II. Cleaning
During the use of industrial valves, dirt and impurities will be generated inside the valve due to corrosion, precipitation and other reasons of the medium. These dirt and impurities will affect the sealing performance and operating performance of the valve, so it needs to be cleaned regularly. When cleaning, you can use water or chemical cleaning agents to remove dirt and impurities.
III. Lubrication
The operating parts of industrial valves, such as valve stems, valve discs, etc., need to be lubricated regularly to ensure flexible operation. When lubricating, you can use lubricating oil or grease and apply it to the operating parts.
IV. Anti-rust
During use, industrial valves are susceptible to corrosion and oxidation by the medium, so they require regular anti-rust treatment. Anti-rust treatment can use anti-rust agent or anti-rust paint, which can be applied to the surface of the valve.
V. Storage
If industrial valves are not used for a long time, they need to be stored in a dry, ventilated place and inspected and maintained regularly. During storage, the valve should be protected from being squeezed and collided by heavy objects to avoid damage to the valve.
VI. Precautions
When maintaining industrial valves, you need to pay attention to the following points:
1. Before maintenance, the valve should be closed and the medium in the pipeline should be drained to avoid danger.
2. Appropriate tools and equipment should be used during maintenance to avoid damaging the valve.
3. After maintenance, the operating parts of the valve should be restored to their original positions and a trial run should be performed to ensure the normal operation of the valve.
4. For some special industrial valves, such as high temperature valves, high pressure valves, etc., they need to be maintained according to relevant regulations.
VII. Conclusion
In short, although the valve is small, it requires a lot of maintenance! Regular "physical examination" and maintenance of butterfly valves, gate valves, and check valves can not only greatly extend their service life, but also keep work efficiency online, quietly saving you a lot of maintenance trouble. TWS is always here. The above are some practical maintenance tips we have shared. We hope they can help you. If you are unsure about anything in actual operation, or need to purchase high-quality valves, please feel free to consult us!
