Description
Technical field
The utility model belongs to technical field of ships, and in particular to a kind of detachable pipeline anti-corrosion for seawaterline
Lose device.
Background technology
Seawaterline is the important composition of Ship Propulsion System, auxiliary system, and main application has cooling, fire-fighting, ballast, water
Curtain, sea water and fresh water displacement etc., wherein seawater cooling is most widely used, since seawater is salting liquid, seawaterline and various kinds of equipment
There are the potential differences between different metal material between heat exchanger, to form the lower metal material of current potential as current potential compared with Gao Jin
The sacrificial anode for belonging to material, causes seawaterline or equipment heat exchanger to corrode and leak.Equipment seawater cooling line at present
Sacrificial anode mostly uses the method for installing spelter additional in equipment heat exchanger or adding iron set on pipeline, sacrificing pipeline section, still
The shortcomings that above method is should not to check the corrosion condition of sacrificial anode, and need detaching pipelines when replacement, be easy to cause and sets
Standby cabin is made dirty by seawater, and practical operation is time-consuming and laborious.
Invention content
For problems of the prior art, the utility model provides a kind of detachable pipeline for seawaterline
Erosion protection system, with realize seawaterline sacrificial anode can effective protection seawaterline and equipment heat exchanger be convenient for scene inspection again
It looks into sacrificial corrosion situation and replacement operation is simple and practicable.
To achieve the above object, the utility model uses following technical scheme：
A kind of detachable pipeline erosion protection system for seawaterline, the device include pipeline and expansion tube, described
It is connected between pipeline and expansion tube, is equipped with fixed column in the accommodating chamber bottom of expansion tube, is arranged in the fixed column sacrificial
Domestic animal anode offers sealed port on the top of expansion tube, and seal cover board is equipped at sealed port, will be close by lifting bolt
Capping plate is connected with the engaging lug on expansion tube side wall, realizes the sealing between seal cover board and expansion tube.
The shape of the sacrificial anode is cylindrical sleeves.
Restraining position ring block is welded on the inner surface of the seal cover board, the internal diameter of the spacing ring is equal to the outer diameter of fixed column.
Gasket is equipped between the seal cover board and sealed port.
The fixed column is welded on the accommodating chamber bottom of expansion tube.
To reduce the weight of whole equipment, the service life of whole equipment, pipeline, expansion tube, seal cover board, limit are improved
Ring is that titanium alloy material makes.
To reduce processing cost, corrosion resistance is improved, service life of equipment, pipeline, expansion tube, seal cover board, limit are extended
Position ring be steel material make, the pipeline, expansion tube, seal cover board, spacing ring inner wall plate modeling.
The both ends of the pipeline are respectively equipped with suction flange and outlet(discharge) flange.
The step of utility model device inspection and replacement sacrificial anode, is as follows：
1. the shut-off valve before and after pipeline is turned off；
2. removing lifting bolt, seal cover board is opened；
3. taking out sacrificial anode, dress is replaced or returned depending on feelings and is continuing with.
The operation principle of the utility model is：When seawater is from suction flange flow ipe, through seawater when expansion tube with sacrifice
Positive contact, sacrificial anode impregnates generates electrolysis in the seawater, and zinc, aluminium, cadmium element are dissolved in seawater in anode, and seawater is along sacrifice
Anode cylinder both sides flow out to outlet(discharge) flange, while being covered in the metal surface of pipeline and equipment inner cavity, form sull,
To improve the anti-corrosion capability of pipeline and equipment.
Compared with prior art, the beneficial effects of the utility model are：
1. the utility model is mainly set the ontology and sacrificial anode that suck thick water filter structure by integrated requirement
Meter is combined together, and optimizes space, the physics principle being electrolysed in the seawater by sacrificial anode, in pipeline and equipment metal watch
Face forms protective film, to greatly improve the corrosion resistance and service life of pipeline equipment.
2. using sacrificial anode as pipeline and the main element of the corrosion-resistant protection of equipment, corrosion resistant performance is relatively reliable steady
It is fixed, use protection longer life expectancy.
3. sacrificial anode is designed as replaceable pattern, the convenience of personnel's Operation and Maintenance is improved.
To sum up, the utility model can be used on all devices seawater cooling line, can effective protection seawaterline and
Equipment heat exchanger, and it is of less demanding to execute-in-place, it is simple and practicable.Whole device reliability is higher, economy is also more preferable, and
Popularization and application is to field needed for each.
