How Much Do You Know About The Maintenance Of American Standard Ball Valves?
Ball Valve During maintenance, attention should also be paid to the water ingress problem in the electric head and its transmission mechanism. Especially the rainwater that seeps in during the rainy season. One is to rust the transmission mechanism or the transmission sleeve, and the other is to freeze in winter. The forged steel American standard ball valve causes excessive torque when the electric valve is operated, and damage to the transmission components will cause the motor to be unloaded or the over-torque protection to trip and fail to achieve electric operation. The transmission components are damaged and manual operation is also impossible. After the over-torque protection is activated, manual operation cannot be switched on and off. If forced operation is performed, the internal alloy components will be damaged.
Steel and iron are alloys based on iron and carbon as the main added element, collectively referred to as iron-carbon alloys.
Put the cast pig iron in a molten iron furnace to melt, that is, cast iron (liquid), and cast the liquid cast iron into castings. This kind of cast iron is called cast iron.
Large-diameter American standard ball valve What is the difference between cast steel and carbon steel. First, steel is classified by chemical composition
(1) Carbon steel: a. Low carbon steel (C≤0.25%); b. Medium carbon steel (C≤0.25~0.60%); c. High carbon steel (C≤0.60%).
Steel is classified by forming method: (1) Forged steel; (2) Cast steel; (3) Hot rolled steel; (4) Cold drawn steel.
American standard ball valves are generally kept in the open position during maintenance, and closed for maintenance in special circumstances. Other valves cannot be treated as open.
