How does the exhaust valve perform exhaust work

Exhaust valves are more commonly used in heating systems or HVAC systems. When the water is heated, hydrogen or oxygen will be released, which will cause a lot of adverse effects, damage or reduce the heating effect. If these gases cannot be discharged in time If it does, it will have a lot of adverse effects, so the use of exhaust valves is indispensable in the pipeline system, and is widely used in boilers, oil and gas, and water supply and drainage pipelines. The exhaust valve is often installed at a high point or elbow to remove excess gas in the pipeline, improve pipeline efficiency and reduce energy consumption. 

If the hot gas inside the pipeline is hot, it may cause oxidation and corrosion of the pipeline and hot water circulation When it is not smooth and unbalanced, it will cause local uneven heat dissipation, local overheating or local heat loss, noise when the pipeline is running with air, and the vortex phenomenon caused by the circulating pump. Exhaust When there is gas overflow in the system, the gas will climb up the pipeline and gather at the higher point of the system rating. When the exhaust valve is installed, it is also at a higher point. The gas enters the upper part of the exhaust valve. When the gas increases and the pressure rises, the gas will cause the water level in the cavity to drop. As the water level drops, the air vent opens to perform exhaust work. 

The exhaust valve is used in the main heating system or heating system, because there is always a certain amount of air dissolved in the water, the solubility of the air will be reduced due to the increase in temperature, so that the gas gradually escapes from the water during the water cycle. It is separated to form bubbles or gas columns. Therefore, exhaust valves are widely used in boilers, oil and gas, and water supply and drainage pipelines. They can remove excess gas in the pipeline, improve the efficiency of pipelines and roads, and reduce energy consumption. If it is discharged, it will cause undesirable consequences and cause oxidation and corrosion of the pipeline. 

Exhaust valves are widely used. The more common ones are float type exhaust valves, float lever type exhaust valves, and cylinder type exhaust valves. Float type exhaust valves have a small exhaust volume and are only suitable for exhaust When the air volume is small; the cylinder type exhaust valve can only discharge a section of air when exhausting, and can not perform continuous exhaust; the cylinder type exhaust valve can discharge at a high speed regardless of pressure or no pressure. The exhaust valve plays an indispensable role in the pipeline.
