The duck mouth application scope and structure characteristics of pneumatic valve

duck mouth pneumatic valve is introduced:
rubber flexible pneumatic valve, check the pneumatic valve is shaped like the duck mouth so often called duckbill pneumatic valve, duckbill pneumatic valve products are two kinds of flange and clamp connection. Duck mouth pneumatic valve is having city drainage system and sewage pipe network is widely used in sewage check pneumatic valve. Duck mouth pneumatic valve for one-piece structure, % of rubber material, built-in nylon cord fabric rubber, no mechanical parts. Pneumatic valve on-off characteristic is good, only through internal pipeline pressure and back pressure to control the pneumatic valve opening and closing the outside world, do not need to run other parts, also do not need to human or electricity. Pneumatic valve can prevent sewage corrosion, pneumatic valve closing, leakage quantity is zero, sealed performance is good.

the application scope of duckbill pneumatic valve:
duck mouth pneumatic valve is widely used in beach, coast, wharf of floods and waste water, sewage discharge and the coastal cities. Pneumatic valve (duck mouth The duck mouth pneumatic valve) Can replace the pneumatic valve flap valve check. Suggest the DN a duck mouth pneumatic valve can use clamp connection or flange connection. Pneumatic valve DN above the duck mouth it is recommended to use flange connection.

duck mouth the structure characteristics of pneumatic valve:
rubber duck mouth pneumatic valve adopts high quality elastic rubber materials, built-in reinforced rubber structure pneumatic valve products, all of them, and it according to the stress analysis and stress calculation, aiming at different working conditions, and using different design mechanism, choose different rubber formula, and according to the special process, and its aerodynamic body and flexible, in particular, to ensure maximum compressive strength at the same time, ensure the hydraulic loss minimum, to achieve the perfect combination of discharge and pressure resistance.
