Product Description

overview

The flap door of the float tank is a check valve product, which is mainly installed

at the end of the drainage pipe to prevent back flow of external water.Material is

divided into stainless steel, carbon steel and other materials.
The product is a one-way valve installed at the outlet of the drainage pipe by the

river. When the tide level of the river is higher than the outlet of the outlet pipe and the

pressure is higher than the pressure in the pipe, the flap door panel of the floating tank

will automatically close to prevent the tide water from pouring back into the drainage

pipe.This product is developed by our company.The product is subject to Q / tf-b2771

industrial technical standard; it is tested according to GB / t13927 test requirements;

equipment nominal pressure (PN): 0.25-1.6mpa; nominal diameter (DN): 200-2000mm.
 

main structure description:

The flapping door of the floating box uses the buoyancy of the empty box structure of the gate leaf in the water to reduce the rear door force, so as to increase the opening angle of the gate leaf.The flap door of the floating tank must be submerged for underwater installation and operation.The flap door is installed at a certain angle to ensure a good seal under the water head of 0.5m.The switch shall befree and flexible. When the flap door is partially submerged in the water, the internal pressure of the pipeline is large and the reverse pressure is small, the flap door allows partial leakage. When the water pressure of the river increases, the flap door will automatically close and seal.

1, simple structure, convenient installation, economic and practical.

2 .The utility model can bear the reverse water head and avoid the phenomenon

    that the conventional duck valve can not bear the reverse pressure and reverse

    suction that can not stop water.

3. because the hinge seat adopts unique technology, it can buffer and adjust,

    which makes the gate bear even force when it is closed, anti fatigue and durable.

4.The gravity and buoyancy of the door cover have been accurately calculated,

   and the secondary hydraulic calibration has been carried out to ensure flexible action,

   small resistance, energy saving and reliable operation.
