русскийThe globe valve of the copper valve manufacturer is a forced sealing valve that needs to apply pressure when closing. It has a simple structure, a small work schedule and a good sealing effect, which has attracted the attention of many enterprises. One of the causes of valve failure in many valve applications is corrosion.
When the globe valve is on the groundwater, if the water level is high, severe corrosion may occur, and the globe valve is not easy to disassemble during maintenance, which affects the construction progress and slows down productivity. When disassembling the globe valve, if the corrosion is severe, the nut will fail. Corrosion can cause premature failure of American standard globe valves, greatly reducing the life of the entire structure and the safety of the valve.
Therefore, the anti-corrosion of the globe valve is very important, and some manufacturers use methods such as buttering the valve to protect it. Commercially available sealants, charging flange gaps, and the entire globe valve surrounded by mineral oil and wax that are not hydrophobic, are very effective. The specific performance is that the gate valve seal is squeezed in a high-pressure environment to keep the package away from the seal. The direct result is that the sealing performance of the gate valve decreases, resulting in the failure of the entire valve seal and medium leakage.
