The invention provides a grating, a self-flowing circulating system and a ship system. The grating comprises a mounting frame and a plurality of grating bars, the mounting frame is connected with an inlet pipeline; the plurality of grid bars are uniformly arranged in the mounting frame, and two ends of the plurality of grid bars are respectively connected with the mounting frame; the cross section of the grid bar is in a water drop shape, and the large end of the water drop shape is an incident flow face. And under the condition that fluid passes through, the fluid can flow from the large end part to the small end part of the water drop shape. Vortex shedding generated at the small end parts of the grid bars when fluid is separated from the grid is reduced, fluid excitation is reduced, and system radiation noise is reduced. The original mounting structure of the grille is not changed, the change of pipelines of a ship system is small, the structural form is simple, and mounting is convenient.

    本发明提供一种格栅、自流循环系统及船舶系统,所述格栅包括:安装框和若干栅条;安装框用于与进口管路连接;若干栅条均匀排布于所述安装框内,且若干栅条的两端分别所述安装框连接;所述栅条的横截面呈水滴形,所述水滴形的大端部为迎流面;在流体通过的情况下,所述流体能够从所述大端部流向所述水滴形的小端部。本发明减少流体与格栅脱离时在栅条的小端部产生涡脱,减小流体激励,降低系统辐射噪声。本发明不改变格栅原有的安装结构,对于船舶系统的管路改动小,结构形式简单,安装方便。
