1.Description.
The single-port exhaust valve should be fitted to the high point of the pipe or where there is a air lock.In the process of carrying water, the water in the pipeline constantly releases tiny gases, which accumulate at the higher point of the pipeline and form air bags, making it difficult to carry water and reducing the system's capacity to carry water.These gases can be removed by a single vent valve.It is suitable for protecting or improving the water delivery efficiency of the system in high-rise buildings and small pumping stations.

6.Operating principle
Exhaust state, buoy, by gravity pull down one end of the lever, the lever in the tilt state at this moment, in the leverage and vent contact appeared gap, air through the vent through the gap, with the air discharge, water level rise, buoy under the effect of the buoyancy of water float upwards, the lever on the seal face pressure on the porosity, gradually until the vent is completely blocked.The exhaust valve is now completely closed.
