Working principle
During normal operation, the small steel ball in the valve will tightly seal the pores connected to the atmosphere due to the action of gravity and pressure inside the pipeline; when a staged vacuum occurs in the pipeline, the internal pressure is negative pressure and the small ball is at the outside air pressure. Under the action, it quickly bounces open, the air can enter, and the vacuum of the pipeline is broken.
