Features
1. The buoy of the exhaust valve adopts low-density PPR and composite materials, which will not deform even if it is immersed in high-temperature water for a long time. Will not cause difficulty in the movement of the pontoon.
2. The buoy lever is made of hard plastic, and the connection between the lever and the buoy and the support adopts a movable connection, so it will not rust during long-term operation and cause the system to fail to work and cause water leakage.
3. The sealing end surface of the lever is supported by springs, which can expand and contract with the movement of the lever to ensure the sealing performance without exhaust.
When the pipe starts to inject water, the plug stays in the open position to perform a large amount of exhaust. When the air is exhausted, water accumulates in the valve, the float is floated, and the plug is driven to the closed position to stop a large amount of exhaust. During normal transportation, if a small amount of air accumulates in the valve to a considerable extent, the water level in the valve drops, and the float ball drops accordingly. At this time, the air is discharged from the small hole. When the pump stops, the water in the pipe is empty or negative pressure is generated in the pipe. At this time, the plug quickly opens to suck in air to ensure that the pipeline is complete.
