What is the Introduction to the Characteristics of Forged Steel Ball Valve
Forged steel ball valves are mainly suitable for cutting off or connecting pipeline media in various systems of thermal power plants. Applicable media: water, steam and other non-corrosive media. Compared with other valve products, forged steel valves are characterized by high temperature and pressure, unique self-sealing design, the higher the pressure, the more reliable the sealing. Because of the special performance, technical characteristics and working conditions, the products also have the characteristics that other products can not replace.
I. Characteristics of Forged Steel Ball Valve
Forged steel ball valves are mainly suitable for cutting off or connecting pipeline media in various systems of thermal power plants. Applicable media: water, steam and other non-corrosive media. Compared with other valve products, forged steel valves are characterized by high temperature and pressure, unique self-sealing design, the higher the pressure, the more reliable the sealing. Because of the special performance, technical characteristics and working conditions, the products also have the characteristics that other products can not replace. Forged steel ball valves often overlook the problem of fat injection. After the greasing gun is refueled, the operator chooses the valve and the connecting mode of the low-temperature globe valve, and then carries out the greasing operation. There are two kinds of forged steel gate valves: on the one hand, less grease injection is insufficient, and the sealing surface accelerates wear due to lack of lubricant. On the other hand, excessive fat injection causes waste. Because there is no accurate calculation of different valve sealing capacity according to the type and type of valve. Sealing capacity can be calculated by valve size and type, and then a reasonable amount of grease can be injected.
II. Maintenance of Forged Steel Ball Valve
Ball valve maintenance is generally in the open state, in special cases choose to close maintenance. Other valves cannot be treated as open valves.
Forging steel extended end gate valve should observe the problem of valve diameter and sealing ring seat leveling. For example, ball valves, if there is an open interference, can adjust the open limit inward, confirm that the path is straight and then lock. Adjusting the limit should not only pursue the position of opening or closing one side, but also consider it as a whole. If the opening is smooth and the closing is not in place, the valve will not be closed properly. Similarly, when adjustments are in place, corresponding adjustments should also be taken into account. Forged steel ball valves ensure the right-angled stroke of the valve. After fat injection, the mouth of fat injection must be sealed. Avoid impurities entering, or lipid oxidation at the lipid injection mouth. Cover with anti-rust grease to avoid rusting. So that it can be applied in the next operation
