Water Hammer(also Known As Water Hammer) Is A Phenomenon Of Sudden And Violent Pressure Fluctuations In Pipeline Systems Caused By Rapid Changes In Water Flow Velocity. It Is Often Caused By Sudden Opening And Closing Of Valves, Start And Stop Of Water Pumps, Etc., Which Can Cause Impact On Pipelines And Connecting Parts. As A Convenient Pipeline Connection Method, The Key To Adapting To Water Hammer Protection Is To Ensure Connection Reliability And Reduce Impact Transmission.

Water Hammer Is Divided Into Positive Water Hammer And Negative Water Hammer. Positive Water Hammer Can Cause A Sudden Increase In Pressure Due To The Obstruction Of Water Flow, Which May Damage Pipeline Interfaces And Valves; Negative Water Hammer Can Easily Cause Thin-walled Pipelines To Collapse Due To The Formation Of Vacuum Inside The Pipeline. The Sealing Performance And Seismic Resistance Of Groove Connections Directly Affect The Safety Of Pipelines Under Water Hammer Impact, And The Quality Of Connections Should Be Given Special Attention.

The Groove Connection Adopts Components Such As Clamps And Sealing Rubber Rings To Connect The Pipeline, Which Has The Characteristics Of Easy Installation, Flexible Disassembly, And Good Sealing, And Is Suitable For Various Pipeline Materials. When Dealing With Water Hammer, It Is Necessary To Use Groove Fittings That Are Suitable For The Pressure Level To Ensure That The Clamps Are Tightened In Place. The Sealing Rubber Ring Should Be Made Of Impact Resistant And High-temperature Resistant Materials To Reduce Interface Leakage Caused By Water Hammer Impact.

At The Same Time, The Groove Connecting Pipeline Needs To Be Equipped With Water Hammer Protection Equipment, Such As Installing Slow Closing Check Valves And Water Hammer Eliminators At The Outlet Of The Water Pump To Slow Down Changes In Water Flow Velocity And Absorb Impact Energy; Avoid Frequent Starting And Stopping Of Water Pumps And Sudden Opening And Closing Of Valves To Reduce Water Hammer From The Source. It Is Widely Used In Water Supply And Drainage, Heating And Other Systems. After Reasonable Adaptation Of Water Hammer Protection Measures, It Can Effectively Improve The Impact Resistance Of Pipeline Systems And Ensure Operational Safety.
