Description

technical field [0001] The invention relates to the field of ships, in particular to an antifreeze seawater valve box. Background technique [0002] Most waters in northern my country have freezing periods, and some river basins have freezing periods as long as half a year. Generally, the seawater valve tanks of ships are straight through. For ships in this navigation area, after the seawater valve tanks freeze, not only the melting period is long, but also the frozen volume expands, which is easy to damage the hull. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an antifreeze seawater valve box. [0004] The technical solution adopted by the present invention to solve the technical problem is: to construct a kind of antifreeze type seawater valve box, including a box body, the bottom of the box body is provided with a water inlet, a short pipe is installed at the water inlet, and the box body A first flange i...
