Product Description


Principle
When water enters into the pipe, the plug will stop at the lower part of Locating bracket to discharge the air by a large quantity. When the air has been discharged completely, water will enter into the valve to make the ball floated, driving the plug closed and exhaust stopped. Under normal operation, there can be little gas gathered onto the upper part in pipe. When it arrives to a certain extent, the water level in valve will lower,and the float ball will lower as well, the air will be discharged out from the small hole. In case of power cut and pump stop, and when the water in pipe is emptied, there can easily cause negative pressure in pipe, and the float ball will lower along with the water. Here, the small hole will be opened, and large quantity of air will come in from the large hole, thus to ensure the safety of pipeline.
Note: it cannot be used in sewage pipeline.
