Compound exhaust valve principle
| The exhaust valve is an indispensable auxiliary component in the pipeline system and is widely used in boilers, air conditioners, oil and gas, water supply and drainage pipes. It is often installed at the commanding heights or elbows to eliminate excess gas in the pipeline, improve the efficiency of the road use and reduce energy consumption. The principle of the composite exhaust valve is: when the water injection starts in the pipe, the plug stays in the open position, and a large amount of exhaust is performed. When the air is exhausted, water is accumulated in the valve, the float is floated, and the plug is driven to the closed position. Stop a large amount of exhaust gas. When the water in the pipe is normally transported, if a small amount of air collects in the valve to a considerable extent, the water level in the valve drops, and the float ball descends. At this time, the air is discharged from the small hole. When the pump stops, the water flow in the pipe When empty or when a negative pressure is generated inside the pipe, the plug is quickly opened and the air is sucked in to ensure the pipeline is complete.
