Because the sewage exhaust valve will produce scum during long-term use, it is necessary to fundamentally solve the problem by installing a filter or filter below the exhaust valve, which can effectively filter out foreign matter such as scum.

Structure and use of sewage exhaust valve:

The exhaust valve is a cylindrical barrel-shaped body, which mainly contains a group B STAINLESS STEEL BALL, rod (FLOAT ARM) and plug head (POPPET). The valve is installed at the pump outlet or in the water distribution pipeline to remove a large amount of air gathered in the pipe, or the trace air gathered at a higher level of the pipeline is discharged to the atmosphere to improve the efficiency of the pipeline and the pump, and once there is negative pressure in the pipe, the exhaust valve quickly inhales the outside air to protect the pipeline caused by negative pressure damage.

Operation principle of sewage exhaust valve: When the tube begins to fill with water, the plug head stays in the open position for a large amount of exhaust, when the air is discharged, water in the valve, the float is floated, drive the plug head to the closed position, stop a large amount of exhaust, when the water in the tube is normally transported, if a small amount of air gathers in the valve to a considerable extent, the water level in the valve drops, the float drops accordingly, at this time the air is discharged by the small hole, when the pump stops, When the water flow in the pipe is empty or when there is negative pressure in the pipe, the plug head is quickly opened and the air is inhaled to ensure that the pipeline is complete.
