Product Desciption
Big Size high-pressure ball valves are mainly used in the pipelines of various systems in thermal power plants to cut off or connect pipeline media. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, high-pressure valves are characterized by high temperature and high pressure, unique self-sealing design, the higher the pressure, the more reliable the seal. Due to the special performance, technical characteristics and working conditions, the product has formed characteristics that other products cannot replace.
Big Size high-pressure ball valves often ignore the problem of grease injection. After the grease injection gun is refueled, the operator selects the valve and the grease injection connection method for the low-temperature stop valve, and then performs the grease injection operation. There are two types of high-pressure gate valves: on the one hand, the amount of grease injection is small, and the grease injection is insufficient, and the sealing surface is worn faster due to lack of lubricant. On the other hand, excessive fat injection causes waste. The reason is that there is no accurate calculation of the sealing capacity of different valves according to the valve type category. The sealing capacity can be calculated based on the valve size and type, and then a reasonable amount of grease can be injected.

Maintenance of large diameter high pressure ball valve
The ball valve is generally in the open position during maintenance. In special circumstances, it is selected to close for maintenance. Other valves cannot be treated as open positions.
For high-pressure extended-end gate valves, observe the problem that the valve diameter is flush with the seal ring seat. For example, for ball valves, if there is an open position interference, the open position limiter can be adjusted inward to confirm that the diameter is straight and locked. Adjusting the limit can not only pursue the opening or closing position, but should be considered as a whole. If the opening position is flush and the closing position is not in place, the valve will not close tightly. In the same way, if the adjustment is in place, the adjustment of the open position should also be considered. The high-pressure high-pressure ball valve ensures the right-angle stroke of the valve. After grease injection, be sure to seal the grease injection port. Avoid the entry of impurities, or the oxidation of lipids at the grease injection port, and the cover should be coated with anti-rust grease to avoid rust. So that it can be applied in the next operation.
High-pressure and low-temperature valves should be considered for specific treatment of specific problems in the sequential transportation of oil products in the future. In view of the different qualities of diesel and gasoline, the scour and decomposition ability of gasoline should be considered. In the future valve operation, when encountering gasoline segment operations, replenish grease in time to prevent wear. When injecting grease, do not ignore the grease injection on the stem of the large-caliber high-pressure ball valve. There is a sliding sleeve or packing on the valve shaft, which also needs to be kept in a lubricated state to reduce frictional resistance during operation. If lubrication cannot be ensured, the torque will increase during electric operation and wear parts will be laborious during manual operation.
