What faults may occur during the operation of cast steel stop valves? What are the causes of these faults?
1. Leakage and liquid leakage: Leakage and liquid leakage of cast steel stop valves are mainly caused by wear and damage of the sealing surface. The damage of the sealing surface is mainly caused by improper material selection, substandard processing accuracy, and loose installation.
2. Inflexible operation: The inflexible operation of cast steel stop valves is mainly caused by damage, blockage, and jamming of internal parts, such as valve stem bending and valve core wear.
3. Leakage: Leakage of cast steel stop valves is mainly caused by damage to the valve stem seal. Seal damage includes seal aging and seal wear, which will make the valve unable to close completely and prone to leakage.
4. Blockage: The blockage of cast steel stop valves may be caused by foreign matter or scale on the valve core.
5. Damage: Damage to the body of cast steel stop valves is mainly caused by external impact and heavy impact.
After recognizing the above common faults, I believe everyone already knows how to avoid them!
