In summary, the marine backflow preventing floor drain and the installation method have the following beneficial effects: the marine anti-backflow floor drain comprises a floor drain cover, a floor drain body, a rail and an anti-backflow device, wherein the four structures are detachably assembled together, so that the occupied space is saved; each structure can be produced and manufactured in a space outside the ship, and the assembly between the structures does not need to adopt a welding mode, so that the marine backflow-preventing floor drain is free from the influence of the ship without a welding space, and corresponding parts can be removed for later maintenance or replacement, and the marine backflow-preventing floor drain is simple and convenient.
The floor drain cover has a double filtering structure, can prevent impurities such as fibers, large particles and the like from entering the pipeline and the backflow preventing device, and effectively prevents the pipeline from being blocked; the opening part of the floor drain body is subjected to rubber vulcanization treatment so as to ensure that the contact surface of the opening and the ship body structure can be effectively sealed and prevent water leakage; the baffle plate limiter is connected with the track by a spring, and rubber vulcanization treatment is carried out on the surface of the baffle plate limiter, so that rigid connection between the clamping groove and the baffle plate limiter is avoided, and the effects of shock absorption and noise reduction are achieved; the anti-backflow device integrates anti-backflow and anti-odor functions by using the reducing pipe and setting the lowest height of the anti-backflow outlet to be higher than the height of the circle center when the floating ball falls on the floating ball blocking piece by coincidence.
The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, it is intended that all equivalent modifications and variations of the invention be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
