Welded Ball ValveWidely Used In Pipeline Transportation Of Oil, Natural Gas, Etc., Strict Adherence To Regulations Is Required To Ensure Operational Safety And Service Life. Before Installation, It Is Necessary To Check The Integrity Of The Valve, Verify The Nameplate Parameters Match The Working Conditions, Blow The Pipeline To Remove Impurities And Welding Slag, And Avoid Damaging The Sealing Surface. When Lifting, It Should Be Hung On The Lifting Ear Or The Central Axis Of The Valve Body, And It Is Strictly Prohibited To Tie It To The Handwheel Or Actuator To Prevent Damage To The Components.

During The Welding Process, The Valve Should Be Opened Moderately At 15 ° -30 ° To Avoid The Valve Chamber Being Sealed And Causing A Sudden Increase In Thermal Pressure, Which Could Damage The Valve Seat And Body. At The Same Time, Control The Heat Input And Take Cooling Measures To Prevent The Temperature Of The Seal From Exceeding 140 ℃. The Quality Of The Weld Seam Must Comply With Relevant Standards. After Welding, Wait For The Valve To Cool To Room Temperature Before Operating To The Fully Open Or Fully Closed Position.

When Operating, It Is Necessary To Open And Close Smoothly, Avoiding Excessive Force. Manual And Electric Operations Must Be Strictly Carried Out According To Regulations To Prevent Damage To The Valve Stem And Valve Core. During Regular Maintenance, It Is Necessary To First Relieve Pipeline Pressure, Disconnect The Power And Gas Sources, And Then Disassemble And Clean. The Cleaning Agent Should Be Compatible With Valve Components And Media, And Non-metallic Parts Should Not Be Soaked For A Long Time.

Proper Amount Of Grease Injection Is Required, And The Dosage Should Be Calculated According To The Valve Size To Avoid Insufficient Wear Or Excessive Waste. The Grease Injection Pressure Should Meet The Requirements. Daily Inspection Of Sealing Performance Is Necessary, And Any Leaks Should Be Dealt With Promptly To Avoid Pressure Maintenance. When Idle, Proper Protection Should Be Taken To Prevent Impurities From Entering And Components From Rusting, Ensuring That The Valve Can Be Put Into Normal Use At Any Time.
