Abstract
The invention discloses a seawater valve box which comprises a door grating, wherein the door grating is a water-scooping type door grating and comprises a plurality of water scooping plates; the water scooping plates are mounted on a grating of the door grating. By the use of the water scooping type grating, and in comparison with a standard flat-bottom grating, the seawater valve box can obtain a larger water intake amount under a condition of an equal-area sea chest opening; the water scooping type grating is more properly used in small-size shallow-draft privately owned boats with higher route speed than the standard grating. By the water scooping type grating, the larger water intake amount can be obtained under the condition of the same sea chest area, so that the phenomenon of air suction of a seawater pump of a main engine is avoided.
Description
Technical field
The invention belongs to equipment of Vessel technical field, particularly a kind of sea chest.
Background technology
Sea chest is mainly used in providing boats and ships main and auxiliary diesel engine cooling water, fire demand water, ballast water, the wash waters such as health, deck and anchor chain, it is directly connected to the normal operation of boats and ships, crewman and the normal life of passenger and the safety of boats and ships and personnel.
Current sea chest exist ship navigate by water in stormy waves and tempo turn under sea situation good situations time, easily there is main frame sea water pump emptying phenomenon.Sea chest design, once defectiveness, often just can expose in the mooring trial stage, and therefore head it off can only carry out at the end of ship building is basic.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of sea chest, solves main frame sea water pump emptying phenomenon.
A kind of sea chest of the present invention, comprises a grid, and described door grid is pocket water type door grid.
As the further improvement of technique scheme, described door grid comprises some pocket water plates.
Another kind as technique scheme improves, and described pocket water plate is arranged on the grid of a grid.
Sea chest of the present invention uses pocket water type grid, can obtain larger flooding quantity when same homalographic sea chest opening relative to the flat grid of standard, in the small-sized civilian boat that shallow draft, the speed of a ship or plane are high, use pocket water type grid more suitable than standard grid.Pocket water type grid makes same sea chest area can obtain larger flooding quantity, avoids main frame sea water pump emptying phenomenon.
Accompanying drawing explanation
Fig. 1 is the door grid schematic diagram of sea chest of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of sea chest that the present invention proposes is described in detail.
As shown in Figure 1, a kind of sea chest of the present invention comprises a grid, and described door grid is pocket water type door grid.Described door grid comprises some pocket water plates.Described pocket water plate is arranged on the grid of a grid.Described height of grid 626mm, described pocket water plate height 50mm.
