Preferably, the through hole is manhole, and it forms four circular ring structures, four circles after being connected with T-shaped sealing ring The internal diameter of ring structure from being followed successively by Φ 266cm, Φ 255cm, Φ 243cm, Φ 232 inside outside.
Preferably, the cover plate is circular cover, and the circular cover lower end both sides are symmetrically installed with two peaces with mounting hole Block is filled, the circular cover is provided with a circular groove, and the diameter of the circular groove from diminishing successively inside outside.
Preferably, the outermost diameter of the circular groove is Φ 194cm, and most inner side is Φ 163cm.
Preferably, the distance between two mounting blocks are 130cm.
Preferably, the through hole is square through hole.
Four mounting holes are arranged with the valve seat.
Preferably, the hinge is formed by connecting rod and installed in the latch of connecting rod two end.
Preferably, the contiguous block being engaged with the mounting blocks is installed on the valve seat, and on mounting blocks and contiguous block Offer the hole passed through for connecting rod.
The present invention is provided with following beneficial effect:
The cast iron flap valve, which is provided with, is only used for the circular and square delivery port of unimodal current, vertebration, reliable operation, Without manual operation, hoisting capacity comes from source pressure, when the hydraulic pressure in flap valve is then opened more than flap valve outside pressure;It is on the contrary then close Close;Suitable for the transformation of farmland water channel, water conservancy system, municipal wastewater, urban flood defence water drainage, sewage treatment plant, waterworks etc..
