To provide a bell-mouth for a ship capable of suppressing an increased discharge time by reducing pressure loss and improving suction capacity while reducing the amount of liquid remaining in a tank by reducing a gap between the bell-mouth and the bottom of the liquid tank.SOLUTION: A bell-mouth 10 for a ship is connected to a fluid suction end in a pipe line of the ship and has a pressure loss reduction section 11 of a bulging shape toward at least one of an outer peripheral direction and an inner peripheral direction on an opening end peripheral edge. The cross-sectional shape of the pressure loss reduction section includes a curved section or is desirable to be a polygonal shape. The pressure loss reduction section is integrally molded on the opening end peripheral edge or is desirable to be a ring-shaped appendage attached to the opening end peripheral edge.SELECTED DRAWING: Figure 1

    【課題】液体タンクの底面との隙間を小さくしてタンク内に残る液体の量を少なくしつつ、圧力損失を低減して吸入能力を向上させることで排出時間の増加を抑制することの可能な、船舶用ベルマウスを提供する。【解決手段】船舶の配管系統の流体吸入端部に接続される船舶用ベルマウス10であって、開口端周縁部に、外周方向及び内周方向の少なくとも1つに向けて膨出する形状の圧力損失低減部11を有する。圧力損失低減部の断面形状が、曲線を含むこと、又は多角形であることが好ましい。また、圧力損失低減部が、開口端周縁部に一体成形されていること、又は開口端周縁部に取り付けられたリング状の付加物であることが好ましい。【選択図】図1
