Abstract

The invention relates to the technical field of flap valves, in particular to a turnover type cast iron deepwater flap valve which comprises a mounting plate, mounting holes are formed in the four face corners of the mounting plate, and a rotating rod is rotationally connected into a rotating sleeve. When the device cannot be normally and automatically started, a user starts a double-shaft motor through a switch, the double-shaft motor can enable a second connecting rotating rod to rotate through a first connecting rotating rod and a first bevel gear, an inner threaded sleeve can rotate through a first toothed rod and a second toothed rod, and a threaded rod can be moved out through the inner threaded sleeve; the threaded rod can jack up the cover plate through the push plate, the rotating roller and the lug plate, the cover plate and the connecting piece do circular motion, at the moment, the cover plate can be opened, the cover plate can be opened when the cover plate cannot be automatically opened, and therefore the situation that a user needs to lift up the cover plate from the bottom end of the cover plate is avoided, and the use safety of the user is improved; and the normal operation of the device can be ensured.

Description

technical field [0001] The invention relates to the technical field of flap doors, in particular to a flip-type cast iron deep-water flap door. Background technique [0002] The flap door is installed at the end of the drainage pipe. It has the function of preventing the backflow of external water. The flap door is mainly composed of four parts: the valve seat, the valve plate, the water sealing ring and the hinge. The shape is divided into round and square. The flap door Traditionally, the material of the valve is a variety of metal products, but now it has developed into a variety of composite materials. The flap door is mainly installed at the end of the drainage pipe to prevent backflow of external water. The material is divided into stainless steel, cast iron, steel, composite material (glass fiber reinforced plastic ) and other materials, the flap door is a kind of one-way valve installed at the outlet of the drainage pipe by the river. When the tide level of the river...
