Composite Exhaust ValveIt Is A Pipeline Exhaust Specialized Valve That Integrates A Large Amount Of Exhaust, Trace Exhaust, And Negative Pressure Air Supply. Its Core Function Is To Discharge A Large Amount Of Air From The Pipeline When Filling Water, Continuously Discharge Trace Air During Operation, And Quickly Suck In Air When The Pipeline Is Under 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, And Connecting Interfaces. 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. Common Models Include CARX, FGP4X, Etc. The Core Highlight Is The Composite Exhaust Structure, Which Adopts A Floating Ball And Lever Linkage Design, Which Can Automatically Identify The Air And Medium Inside The Pipeline, Achieve Automatic Start Stop Exhaust, And Have Dual Functions Of Exhaust And Air Supply Without Manual Intervention. Some Models Use A Specific Diameter Floating Ball With A Conical Inlet Design To Prevent High-speed Airflow From Blowing And Blocking The Exhaust Port.

The Core Features Are Distinct, With Clear Exhaust Division Of Labor, Which Can Quickly Remove A Large Amount Of Air When The Pipeline Is Filled With Water, Continuously Discharge Trace Amounts Of Air Generated During Operation, And Quickly Inhale Air 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, With High Cost-effectiveness And Wide Applicability.

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. It Can Also Be Used In Sewage Transportation Pipelines (special Sewage Type). Compared To Ordinary Single Port And Double Port Exhaust Valves, Its Functions Are More Comprehensive, Taking Into Account Both Exhaust And Air Supply, Which Can Better Ensure The Efficiency And Safety Of Pipeline Operation. It Is The Preferred Exhaust Accessory For Various Medium And Large Pipeline Systems.
