With the rapid advancement of modern industry, fluid control technology has become increasingly significant. Among various types of ball valves, Fully Welded Ball Valves have gained preference in both the chemical industry and the oil and natural gas sectors due to their exceptional performance and reliability. This paper offers an in-depth analysis of the operational guidelines, maintenance necessities, and the crucial role of Fully Welded Ball Valves in ensuring the efficiency and safety of industrial processes.
Proper control is fundamental to the operation of Fully Welded Ball Valves. Ensuring accurate control not only guarantees the right flow but also prolongs the valve’s service life. Here are the key steps for operating these ball valves.
Prior to performing this, ensure that the power or gas source of the valve is connected and the valve’s manual or automatic control system is functioning correctly. Then, turn the handle slowly or actuate the actuator so that the ball rotates 90° in the valve seat to open the valve. At this point, you should consider the care with which you pursue the speed of opening to ensure you do not damage the valve due to operation that is too fast.
Perform the opposite operation of opening the valve to slowly close the valve by rotating the handle in the reverse direction or activating the actuator to make the valve ball return to its initial position. After closing, verify whether the sealing performance of the valve meets the requirement of no leakage.
Regularly switching the fully welded ball valve can not only prevent fine impurities from adhering to the surface of the valve seat and the ball, but also maintain the switching flexibility of the ball valve and check whether the closing function is reliable.
To extend the lifespan of Fully Welded Ball Valves and ensure stable operation under extreme conditions such as high pressure and temperature, regular maintenance is crucial. Here are the general maintenance guidelines:
Upon the completion of heating/cooling, close the ball valve in place and keep the pipeline and valve full of water to ensure that the pipeline is full of water and not oxidized or corroded.
Regularly check all operating conditions of Fully Welded Ball Valves, especially the following main components.
Examine whether the valve body has visible corrosion, cracking, or damage to the exterior. For fully welded ball valves, the structural characteristics place more stress on the condition of the weld because the accessories are welded as opposed to being flanged.
For hand-operated ball valves, the handle should feel "springy" to enable ease of opening and closing. In actuated ball valves, check the power supply, and air or hydraulic supply to the actuator for being in good working condition as well as correctly transmitting the control signal.
The valve seat and seal are important components of the ball valve. These components should be checked regularly for wear and aging. Damaged seals can cause valve failure, especially when working in high temperature, high pressure or corrosive media environments.
After long-term use, dirt and sediment will accumulate inside the ball valve, affecting the movement of the valve core and damaging the seal, so it is necessary to clean it.
The valve surface, especially the dust and dirt on the welds, needs to be cleaned regularly to prevent corrosion and material aging.
If it is found that the valve cannot be opened and closed normally or the sealing performance is poor, the valve may need to be disassembled for internal cleaning. It is recommended to be carried out by a qualified technician to prevent damage to the sensitive internal components of the valve.
As a crucial part of the pipeline system, the operation and maintenance of ball valves directly impact the overall safety and efficiency of the system. Proper operating procedures, regular inspections, cleaning, and timely seal replacements can significantly extend the service life of Fully Welded Ball Valves and mitigate unnecessary failures. Users should design maintenance plans tailored to actual operating conditions and frequency of use to ensure that the Fully Welded Ball Valves are always in optimal working condition.
