How To Prolong The Service Life Of Fluorine-lined Gate Valve

To extend the service life of Lined Gate Valve, the following measures can be taken:

1. Regular inspection and maintenance

Sealing performance inspection: Regularly check the sealing performance of the valve to ensure that the valve is well sealed. You can check by observing whether the valve is leaking, or spraying a layer of soapy water on the valve to observe whether bubbles are generated.

Use pressure test and other methods to conduct more stringent inspections on the sealing to ensure the sealing of the valve under high pressure.

Operating parts inspection: Check the operating parts of the valve, such as handwheels, motors, etc., to ensure that they are flexible and reliable.

If the operating parts are found to be abnormal, such as stuck, loose or damaged, they should be repaired or replaced in time.

Impurity cleaning: Regularly clean the impurities inside the valve to prevent the accumulation of impurities from affecting the normal operation of the valve. The valve can be opened and the impurities inside can be rinsed clean with water or appropriate detergent.

2. Lubrication and protection

Lubrication of moving parts: Regularly lubricate the moving parts of the valve, such as bearings, slide rails, etc., to reduce wear and friction. Use an appropriate amount of lubricating oil or grease for lubrication, and ensure that the lubricant meets the requirements of the valve material.

Rust prevention: When the valve is not used for a long time, the valve should be closed and protected. A layer of rust inhibitor can be sprayed on the surface of the valve to prevent oxidation and corrosion.

For valves that are stored for a long time, it is recommended to keep the sealing pair slightly open and separated to avoid deformation of the sealing surface under long-term pressure.

3. Use environment control

Temperature and pressure: Pay attention to the temperature and pressure of the valve use environment to ensure that the use conditions of the valve are within the allowable range. Avoid valve damage or leakage due to improper operation.

Medium compatibility: Ensure that the medium is compatible with the valve material to avoid corrosion or damage to the valve by the medium.

4. Correct installation and operation

Correct installation: Install the valve strictly in accordance with the installation instructions, ensure that the flange nuts are tightened evenly in sequence in the diagonal direction (symmetrically), and with appropriate torque.

The flange cover of the fluorine-lined valve cannot be opened at will unless it is ready to be connected to the pipeline to protect the PTFE flange surface from damage.

Standard operation: During use, the operating procedures should be followed to avoid excessive or improper operation of the valve.

5. Regular inspection and evaluation

Regular inspection: Regularly conduct comprehensive inspections on valves, including appearance, material, sealing, operational flexibility, etc.

Performance evaluation: Evaluate the performance of the valve based on the test results to promptly discover and solve problems.

6. Other precautions

During the maintenance process, attention should be paid to safety to avoid misoperation and accidents.

For important valves or systems, it is recommended to establish a regular maintenance and inspection system to ensure the long-term stable operation of the valve.

Through the implementation of the above measures, the service life of the fluorine-lined gate valve can be effectively extended, and its efficiency and safety can be improved.
