The gas pipeline is a component that everyone usually encounters. When the valve is used for a long time, there may be some minor problems. At this time, we need to judge it and eliminate the fault. Usually, the inner leakage of the ball valve is the gas pipeline. One of the most common problems with ball valves is that there are many reasons for the internal leakage of the ball valve. Firstly, the cause of the internal leakage of the valve during the construction period, such as the overall damage of the valve caused by improper transportation and lifting, causes the internal leakage of the valve; The valve was not dried and treated to prevent internal corrosion of the sealing surface; the construction site protection was not in place, no blind plates were installed at both ends of the valve, and impurities such as rainwater and sand entered the valve seat, causing leakage; The valve seat injects grease, causing impurities to enter the rear of the valve seat, or burns causing internal leakage during welding; the valve is not installed in the full open position, causing damage to the ball. If the valve is not in the full open position during welding, the welding spatter will Causes damage to the sphere. When the sphere with the welding spatter is attached to the switch, the valve seat will be damaged, resulting in internal leakage; Construction remnants cause scratching the sealing surface; factory-installed or not to cause leakage accurate time position, if the stem drive sleeve assembly or other accessory with angular displacement, the valve will leak. Sometimes improper cleaning causes damage to the sealing surface, and there are also long-term unmaintained or inactive valves, which cause the valve seat and the ball to lock. In many cases, industrial proportional valves such as proportional valves and some special proportional adjustments When the valve is in working state, the valve will cause seal damage and internal leakage will also be affected; many large-diameter ball valves have large stem stop blocks. If the valve is used for a long time, the valve stem and the stem stop block are caused by corrosion and the like. There will be rust, dust, paint and other debris, which will cause the valve to not rotate into place and cause leakage -
If the valve is buried, the extended stem will generate and drop more rust and impurities, preventing the ball from rotating in place, causing the valve to leak, so it is necessary to clean and clear the valve regularly.
