The transportation, installation, production and operation, and maintenance of the valve may all be the root cause of the internal leakage of the valve, so preventive measures also run throughout the whole process. Let's take a look at how to properly prevent the internal leakage of High-Pressure Floating Ball Valves ?
1. New valve acceptance: The valve acceptance process focuses on checking whether the spherical surface and valve seat are intact and free of scratches and whether the sealing performance of the soft seal is good. At the same time, we check whether the auxiliary configuration, such as the grease injection nozzle and the inner check valve is in good condition. The grease injection nozzle and the inner check valve are the only way to "connect" the inside and outside of the valve, and their integrity ensures the smooth flow of the grease injection channel.
2. Protection and cleaning before installation: temporarily protect both sides of the valve during the installation and construction of the pipeline to avoid the entry of rainwater, dust, mud, sand, sundries, etc., which will affect the sealing performance of the valve; the valve must be installed during the installation process. Clean, control the sealing state of the valve, ensure that there is no foreign matter inside, effectively protect the valve seal, and reduce seal damage, these requirements And measures are the keys to avoiding internal leakage of the valve in the future.
3. Correct operation and maintenance: operate strictly in accordance with the valve operation specifications, and strictly prohibit multi-person operation, afterburner operation, and brute force operation. If the valve is abnormal, pay more attention, find the cause the first time, and take corresponding measures.
4. Regular maintenance: For the operation of valve management and maintenance, the most important thing is that preventive and maintenance measures should be in place on time, and the valve should be inspected and maintained regularly. When the valve is found to have internal leakage, the valve should be immediately Checked and repaired to prevent the further expansion of the degree of endoleak.
