Scheme as a further preference has the choked flow protrusion for reducing flow, choked flow protrusion court for one week in the nozzle
It is slot to the side of fire protection pipeline, is to expand mouth towards the side of mixing duct.
Scheme as a further preference, one end of the fire protection pipeline are connected to seawater suction pump, and the other end is provided with
Bilge discharge pipe.
Scheme as a further preference is provided with the first valve on each suction piping, sets on the negative-pressure pipeline
It is equipped with the second valve, is provided with valve on the fire protection pipeline at the negative pressure cavity both ends.
Compared with prior art, a kind of residual water of washing of tanks of the utility model removes system, matches in conjunction with existing fire protection pipeline
It closes and uses, the checkout time of the residual water of washing of tanks can be shortened, improve the elimination efficiency of the residual water of washing of tanks, reduce the working strength of crewman.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of negative pressure cavity；
Wherein, 1- jet pump, 2- negative pressure cavity, 3- nozzle, 4- mixing duct, 5- negative-pressure pipeline, 6- vacuum pipe, 7- water suction
Pipeline, 8- drinking-water pipe, 9- bilge discharge pipe, the first valve of 10-, the second valve of 11-.
Specific embodiment
The optimal technical scheme that according to the present invention will be described in detail below with reference to the accompanying drawings.
A kind of residual water of washing of tanks of the utility model removes system, is dedicated to quickly removing the residual water of washing of tanks, and guarantee that crewman exists
It more easily transports, installs in the course of work, store relevant device and tool, reduce crewman's working strength, improve working efficiency,
It cuts operating costs.
It is mainly included in the jet pump 1 being arranged on fire protection pipeline in cabin, the jet pump 1 includes negative pressure cavity 2, negative pressure cavity 2
For three-port structure, wherein a port plant is provided with nozzle 3, and a port plant is provided with mixing duct 4, a port
It is provided with negative-pressure pipeline 5；
One connection fire protection pipeline of nozzle 3, other end are located at the nozzle of mixing duct 4, have within one week in nozzle 3 and subtract
The choked flow protrusion of small flow, choked flow protrusion are slot towards the side of fire protection pipeline, are to expand towards the side of mixing duct 4
