Product Overview
Forged steel cryogenic 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 characteristics of performance and technology and working conditions, the products also have the characteristics that other products can not replace.
Forged steel check valve should pay attention to the problem of blowdown and pressure relief by wire plug. After the valve pressure test, the gas and water in the valve chamber of the sealing chamber will be pressurized due to the increase of ambient temperature. When injecting grease, it is necessary to discharge and relieve pressure first, so as to facilitate the smooth operation of injecting grease. After the grease injection, the air and water in the sealing chamber are fully replaced. Release the pressure of the valve chamber in time, which also ensures the safety of the valve. After the fat injection, we must tighten the blowdown and pressure relief wire blockage to prevent accidents. When injecting fat, we should pay attention to the problem of uniformity of fat. During normal lipid injection, the nearest lipid outlet from the lipid injection mouth first produces lipid, then to the low point, and finally to the high point, and then to the grease step by step. If not in accordance with the rules or without grease, prove that there is blockage, timely clearance treatment.
Forged steel globe valves pay attention to the problem of valve on-off position. Ball valve maintenance is generally in the open state, in special cases choose to close maintenance. Other valves should not be treated as open valves. Forged steel globe valves must be closed during maintenance to ensure that grease is filled with sealing grooves along the sealing ring. If opened, the grease will fall directly into the flow channel or valve chamber, causing waste. When valve is greased, the effect of grease injection is often neglected. The pressure, the amount of fat injected and the switch position are all normal in the operation of fat injection. However, in order to ensure the grease injection effect of the valve, sometimes it is necessary to open or close the valve, check the lubrication effect, and confirm that the surface of the valve ball or gate is lubricated evenly.
