High Speed Composite Exhaust ValveIt Is A Specialized Valve For Pipeline Exhaust That Integrates High-speed Exhaust, Micro Exhaust, And Negative Pressure Air Supply. Its Core Function Is To Discharge A Large Amount Of Air From The Pipeline At High Speed During Water Filling, Continuously Discharge A Small Amount Of Air During Operation, And Quickly Suck In Air During Pipeline Negative Pressure To Prevent Air Blockage, Cavitation, And Negative Pressure Damage To The Pipeline. It Meets Relevant Industry Standards And Is Widely Used In Long-distance Water Supply, HVAC, Industrial And Other Pipeline Systems. It Is A Key Auxiliary Valve To Ensure Efficient And Safe Operation Of Pipelines.

Structurally, It Mainly Consists Of A Valve Body, A Composite Exhaust Mechanism, A Floating Ball Component, A Buffer Device, And A Flange Interface. The Valve Body Is Mostly Made Of Cast Iron Or Stainless Steel, The Floating Ball Is Made Of Stainless Steel, And The Sealing Element Is Made Of Corrosion-resistant Materials Such As Nitrile Rubber. The Core Highlight Is The High-speed Exhaust Structure And Composite Function, Using A Specific Diameter Floating Ball With A Conical Inlet Design To Prevent High-speed Airflow From Blocking The Exhaust Port. The Built-in Buffer Spring Structure Reduces The Impact Of The Floating Ball And Extends Its Service Life. The Exhaust Mechanism Is Linked To The Floating Ball To Achieve Automatic Start Stop, While Also Having Dual Functions Of Exhaust And Air Supply, Without The Need For Manual Intervention.

The Core Features Are Distinct, With High Exhaust Efficiency. When Filling With Water, It Can Quickly Exhaust A Large Amount Of Air, Continuously Discharge Trace Amounts Of Air During Operation, And Quickly Inhale When Draining Water; Reliable Anti Blowing And Blocking Design, Avoiding Exhaust Failure, Suitable For Media With Nominal Pressure Of 0.1~2.5MPa And ≤ 80 ℃; The Automatic Air Supply Function Can Prevent Pipeline Negative Pressure Deformation And Alleviate Water Hammer Hazards; Compact Structure, Easy Maintenance, Tight Sealing Without Leakage, Can Be Vertically Installed At High Points Of Pipelines, Compatible With Various Pipe Diameters, And Some Models Can Be Easily Disassembled And Repaired.

It Has A Wide Range Of Application Scenarios And Is Commonly Used In Long-distance Water Pipelines, Municipal Water Supply And Drainage Main Pipelines, HVAC Systems, Water Pump Outlet Pipelines, Etc. It Is Especially Suitable For Situations Where Pipeline Laying Is Long, Water Filling And Exhaust Volume Is Large, Or Negative Pressure Is Easily Generated. Compared To Ordinary Dual Port Exhaust Valves, Its Exhaust Speed Is Faster, Its Functions Are More Comprehensive, And It Also Has The Function Of Replenishing Air And Preventing Negative Pressure, Which Can Better Ensure The Efficiency And Safety Of Pipeline Operation. It Is The Preferred Exhaust Accessory For Complex Pipeline Systems.
