Briefly Explain The Main Characteristics Of Flange Ball Valves And Welded Ball Valves

1 Piece Ball Valve requires maintenance and upkeep during use, and this maintenance is a daily routine that must be done every day. Only with proper maintenance and upkeep can the service life of flange ball valves be extended, allowing them to fully utilize their advantages and serve us. So, how should flange ball valves be maintained and serviced?

1、 Be sure to check the valve switch indicator and valve number plate clearly to ensure that the identification is clear. If the label is damaged or detached, it should be promptly supplemented.

2、 Check the bolts at each bracket and connection of the flange ball valve to see if they are well connected. If there is any looseness, tighten them again.

3、 Check the condition of key parts of the flange ball valve, including the packing gland, oil filling hole, oil filling hole nut, plug, expansion joint, valve cover and valve body connection, etc., to see if there are any abnormal conditions in these components. Ensure that all components are functioning properly.

4、 In addition to the daily inspection work mentioned above, a major maintenance is also required once a year. Thoroughly inspect all aspects of the equipment to promptly troubleshoot and avoid significant losses caused by malfunctions.

In short, the maintenance and upkeep of flange ball valves is very important, and sticking to it can achieve good results. If the operation is improper or maintenance is not paid attention to, the valve will inevitably malfunction. Leakage of flange ball valves is a common problem. When a flange ball valve malfunctions, it should be dealt with immediately, but it is important to seek professional maintenance personnel to handle it. Generally, if you purchase a flanged ball valve from a large manufacturer, the manufacturer can provide after-sales service. Therefore, if you have any problems, contacting the manufacturer can solve your troubles.

Pipeline transportation systems play an important role in the transportation of energy fluids such as natural gas, coal, oil, water, and chemical solvents. It is said that more than 90% of natural gas in China is transported through pipeline systems, and valve control is an important component of pipeline systems. So, what are the basic performance requirements for welded ball valves? Below is an introduction for everyone.

1、 Zero level seal

The sealing requirements for welded ball valves, ordering valves, butterfly valves, and globe valves must be zero level in order to ensure effective cutoff of downstream pipelines. If there are metal particles in the liquid medium being transported, it may affect the sealing effect of the valve. The sealing of the valve has a difference between primary sealing and secondary sealing. The former is a metal to metal seal, while the latter is a metal to rubber or PTFE material seal. If sealing failure or medium leakage occurs during medium transportation, emergency sealing should be carried out to minimize the impact loss.

2、 Fire and static electricity prevention

The fire and anti-static design of welded ball valves should also be done to the best, otherwise, once a fire occurs, it will cause external and internal leakage, resulting in losses. If there are problems with the pipeline transportation system of natural gas or chemical plants, there are also significant safety hazards. When the ball part of the welded ball valve is rubbed and clamped by non-metallic substances, it is easy to cause static electricity, so the ball must be conductive with the valve body. If it is transporting corrosive chemical media fluids, then welded ball valves made of anti-corrosion materials should be selected.

In addition, welded ball valves also have basic properties such as temperature difference resistance, pressure resistance, and wear resistance. The quality performance of welded ball valves is directly related to their manufacturing materials and production technology. Therefore, when purchasing welded ball valves, it is essential to find a reliable manufacturer as the top priority.
