use:
   Applied to waterproof system, discharge system, pump outlet, lifting pump station and submerged aeration system.
Features:
   The rubber flange is integrated with the valve body and is extremely easy to install. The valve body adopts an all-rubber design, which does not cause silting and stuck things, reduces maintenance costs, and allows solid particles to pass smoothly.
Manufacturing materials:
     Neoprene, Hepron, NBR, EPR, etc.
Installation method and size:
        It is made of rubber flange, valve body and duckbill. It is made of gasketed metal flange. It can be naturally connected with the metal flange and directly installed on the tank, pipe and cofferdam. When installing and connecting, the flange and the connecting flange should correspond to the size of the connecting flange. Between the flange and the connecting flange, waterproof glue should be added according to the actual situation to ensure absolute sealing after the joint is tightened. Also, care must be taken not to damage the rubber sewage check valve. Flange lips. Flange duckbill valve is a new type of water supply and drainage valve product with all-rubber structure and appearance of “buck-like” and “positive entry, reverse backstop” function. Based on force analysis and force calculation, it adopts different design mechanisms for different working conditions, selects different rubber formulas, and manufactures them according to special processes. When working in the forward direction, the water flows in from the inlet and the water pressure is small, so that the valve can be opened. The greater the water pressure, the larger the opening of the valve and the greater the flow of water. When working in the reverse direction, the valve naturally closes and the seal is reversed. The greater the back pressure, the tighter the valve and the better the sealing effect. It is widely used in various water outlets such as municipal, water conservancy, and sewage treatment to prevent back pouring and back flow, and it is an ideal product to replace the flapping door.
