The product is used for the highest point on the sewage pipe or the gas closure place, to remove the gas in the sewage pipe to dredge the pipe, so that the pipeline operation is normal, if the valve is not installed, the pipeline will appear closed gas, so that the sewage flow rate is affected, or even interrupted. If there is power failure, stop, negative pressure in the pipe at any time, will cause pipe vibration or rupture, exhaust, suction valve will quickly inhale air, prevent pipeline vibration or rupture. The product is used at the highest point of sewage management or a gas closing place, to remove the gas in the sewage pipe to dredge the pipeline, so that the pipe, if the valve is not installed, the pipeline will appear closed gas, so that the sewage flow rate is affected, or even closed gas, so that the sewage flow rate is affected, or even interrupted. If there is a power failure to stop the pump, negative pressure appears in the pipe at any time, which will cause pipe vibration or rupture. The exhaust and suction valve will quickly inhale air to prevent vibration or rupture of the pipe.
When the internal logistics in the pipe is in operation, the valve stops the lower part of the positioning frame and conducts a lot of exhaust. When the air is discharged, the sewage enters the method to float the ball, drive the valve to close, and stop the exhaust. When the pipe is running, a small amount of gas is naturally produced, and the gas will be concentrated in the pipe to work, to a considerable extent, the sewage in the valve drops, the floating ball drops smoothly, and the gas is discharged from the hole. If there is power failure, pump stop, the water flow in the pipe is negative pressure at any time, the floating ball drops smoothly, open the hole to drive the large hole to fill a large amount of gas supply to ensure the safety of the pipeline.
Note: the pressure of the exhaust valve should not be lower than 0.02MPa during use. If it is lower than 0.02MPa, the exhaust valve is prone to water leakage, and the valve must be equipped with a valve for maintenance.
