Abstract
The utility model discloses a corrosion resistant seawater sluice valve. The sluice valve comprises a sluice valve body which is connected with two pipelines and a flashboard which is inserted between the two pipelines. A groove is arranged on the sluice valve body and at the position which is corresponding to the flashboard. The flashboard is inserted into the groove. The two sides of the groove are respectively provided with a closed ring, wherein the two sides of the grooves contact the flashboard. Due to the fact that the sluice valve body is provided with the closed rings which can be replaced, service life of the sluice valve is prolonged. Meanwhile, due to the fact that added zinc blocks are used for slowing the speed of electrons emitted by a steel sluice valve, corrosion process of the sluice valve is prolonged. Due to the fact that a partial modularized replacing mode is used for replacing a whole replacing mode, not only is cost saved, but also the partial modularized replacing mode is capable of being adapted to other sluice valves of the same type. The corrosion resistant seawater sluice valve provides a new solution for corrosion of the sluice valve caused by seawater.
