Stainless steel flap door

The stainless steel flap door cover is equipped with a pull ring. The opening angle of the pull ring should be greater than 60 degrees without jamming. The switch should be free and flexible. When the flap door is partially immersed in water, the internal pressure of the pipe is large, and the reverse pressure is small, the allowable leakage of the flap door is limited

product details

  Stainless steel flap door The cover is equipped with a pull ring to pull the pull ring. The opening angle of the cover should be greater than 60 degrees without jamming. The switch should be free and flexible. When the flap door is partially immersed in water, the internal pressure of the pipe is large, and the reverse pressure is small, the clap door can be allowed to leak. When the water pressure in the river increases, the flap door will automatically close and seal, and the advanced enterprise management mode will be selected High tech company. We are mainly engaged in water conservancy engineering, waterstop, gate hoist, cast iron inlaid copper gate, steel gate, HDPE flap door, composite material flap door, gate equipment, clapper equipment design, technology development, sales, manufacturing, device integration of modern scale water conservancy engineering enterprises.
 
Main features:
It has simple structure and good sealing performance. It has the advantages of light structure, small running resistance and low impact force. The floating weight in the water is small and the opening angle is large, which can effectively reduce the flow resistance and save energy and electricity. Because of its light weight and small transformation inertia, the angular velocity and impact force before closing are reduced. The stress condition is improved, and its strength and rigidity are good. The installation mode is flange structure, and the installation is convenient. It can save electric energy, manpower, hydrolysis fee, etc. The door leaf is a sealed cavity structure with small specific gravity. There is no need to hang the counterweight;
 
 
 
 
Advantages of stainless steel flap door:
Stainless steel flap door belongs to the field of drainage engineering, which depends on the drainage pipe which is discharged into the river channel to prevent the backflow of river water. Background technology urban rainwater drainage is generally organized drainage. Rainwater from roads and blocks is discharged into river channels through drainage pipes. The flood control standard of river channel is higher, and the standard of drainage pipeline is lower than that of river. Even if the rainfall is small and medium, the water level of drainage pipeline is higher, and the water level of river channel is relatively low. Rainwater can be discharged into river channel through pipeline. In the flat terrain area, the elevation difference between the outlet of the drainage pipeline and the river channel is small. When the river water level rises in the rainstorm, the river water flows back into the drainage pipeline, which will cause waterlogging. Therefore, it is necessary to install clappers when the drainage pipes are discharged into the river outfall in many flat areas.
