1. The traditional rubber diaphragm of the aerator is changed to a rubber diaphragm with extension compensation, which can freely rebound and avoid the tearing and falling off of the diaphragm caused by stress concentration. A reverse folding structure with better sealing performance is adopted between the diaphragm and the support plate, which greatly extends the service life and effectively avoids the phenomenon of diaphragm falling off.
2. The diaphragm adopts an internal check valve design - a thickened center without holes. When the air supply is turned off, under the effect of water pressure and the elasticity of the diaphragm itself, the center of the diaphragm falls back and precisely covers the air release holes in the unperforated area of the support plate, just like a check valve, which can prevent the liquid from flowing back into the aeration system.
3. The diaphragm is made of imported ethylene propylene diene monomer (EPDM) rubber, which is anti-aging, corrosion-resistant, acid and alkali resistant, and durable. The connection between the aerator and the pipeline adopts a unique connection method, which makes the pipeline connection more secure, has better sealing performance, and can effectively prevent the loosening of the connection parts caused by the vibration generated during aeration work.
