Embodiment
For utility model content, feature and effect of the present utility model can be further appreciated that, following examples are hereby enumerated, and
Accompanying drawing is coordinated to describe in detail as follows：
Refering to accompanying drawing 1.
Embodiment 1
A kind of dredger central cooler back purge system, is made up of sea water pump, valve and pipeline, seawater pump intake warp
Valve, sea water filter connection outboard, seawater pump discharge by the road, valve be connected in parallel two sets of central coolers, two sets of central coolers
Seawer outlet connects sea water pump entrance pipe and outboard through valve, the pipeline connection between two sets of central cooler seawater inlets and valve
Screw down nonreturn valve is backwashed, backwash screw down nonreturn valve connects outboard by pipeline through kingston valve.
Backwash screw down nonreturn valve uses DN100 screw down nonreturn valves, caliber 100mm.Kingston valve is stopped from DN100
Return valve.Backwash screw down nonreturn valve is copper material, and pipeline takes stainless steel or galvanized pipe, and pressure rating is more than 0.3Mpa.Pipe
Road is connected with backwash screw down nonreturn valve using flange, is linked together between pipeline by way of welding.
The present embodiment concrete structure and its implementation process：
A kind of dredger central cooler back purge system, is made up of sea water pump, valve and pipeline.Backwash part includes
3 copper screw down nonreturn valves of DN100, caliber are 100mm stainless steel pipeline.Wherein 3 copper screw down nonreturn valves of DN100 pass through
Flange connects, and the stress levels of stainless steel pipeline are 0.3mpa.Linking by being welded to connect between pipeline and pipeline.
Dredger central cooler back purge system is backwashed by the way of being set up in former ship to central cooler
Operation.It is 100mm stainless steel tube and 3 copper screw down nonreturn valves of DN100 from caliber, and opens up special maritime mouth, realizes
Function.Stainless steel tube is welded between former central cooler import and inlet valve, two coolers set up flushing line separately, and collect
