Soft-sealed Gate ValveWidely Used In Water Supply And Drainage, Municipal And Other Fields, Common Faults Mainly Include Leakage, Difficulty In Opening And Closing, Valve Stem Jamming, Etc. Targeted Solutions Need To Be Taken To Quickly Restore The Normal Operation Of Valves, Ensure The Stability Of Pipeline Systems, And Control The Total Word Count Within 500 Words.

Leakage Is A Common Fault, Divided Into Valve Stem Leakage And Valve Body Sealing Surface Leakage. Valve Stem Leakage Is Often Caused By Aging And Loosening Of The Packing. It Is Necessary To Disassemble The Valve Stem, Replace It With Suitable High-temperature And Corrosion-resistant Packing, And Evenly Tighten The Packing Gland; Sealing Surface Leakage Is Often Caused By Wear And Tear Of Medium Impurities Or Aging Of Sealing Components. It Can Be Repaired By Polishing The Sealing Surface Or Directly Replaced With A New Soft Sealing Component. After Replacement, A Sealing Test Is Required.

The Main Reasons For Difficulty In Opening And Closing Are Valve Stem Corrosion, Gate Jamming, Or Medium Crystallization Blockage. Apply Lubricating Oil To The Valve Stem To Remove Rust, Disassemble The Valve And Clean Impurities At The Gate. If The Medium Crystallizes, Rinse The Valve Chamber With An Appropriate Solvent; If The Valve Stem Is Bent Or Deformed, It Needs To Be Corrected Or Replaced To Avoid Forcefully Opening And Closing And Damaging Components.

Valve Stem Jamming Is Often Caused By Long-term Lack Of Maintenance, Severe Corrosion, Or Overly Tight Packing. First, Loosen The Packing Gland, Soak The Valve Stem In Rust Remover, Slowly Turn The Handwheel, And Do Not Use Force To Operate; Long Term Idle Valves Need To Be Opened And Closed Regularly And Coated With Rust Proof Oil. In Addition, If There Is An Abnormal Flow Rate In The Valve, It Is Necessary To Check Whether The Gate Opening Is In Place, Clean Up The Debris In The Pipeline, And Ensure That The Valve Can Play Its Regulating Role Normally.
