Forged steel pneumatic valve maintenance matters needing attention

pneumatic valve maintenance, also pay attention to the water problems in electric head and its transmission mechanism. Especially in the rainy season infiltration of rainwater. It is rust the actuator or the shaft sleeve, the second is the winter freeze. Damaged electric pneumatic valve operating torque is too big, when driving part can make the motor no-load jumped or super torque protection cannot be achieved electric operation. Driving part is damaged, manual operation can't. After the super torque protection operation, manual operation is also unable to switch, such as forced operation, will damage the internal metal parts.
iron and steel is based on iron, add carbon as the main elements of the alloy, collectively known as the iron carbon alloy.
the casting pig iron in the cupola melting, namely get cast iron ( Liquid) , the liquid cast iron is cast into the casting, the cast iron is cast iron pieces.
and cast steel and carbon steel where is difference. First, steel classified by chemical composition
( Carbon steel: a. Low carbon steel ( C≤。 %） ； b。 Medium carbon steel ( C≤。 ~。 %） ； c。 High carbon steel ( C≤。 %） 。
steel classification: (press forming method Forged steel. ( Cast steel; ( Hot rolled steel. ( Cold drawn steel.
