Alloy permeation aseptic technic overcomes the problem of traditional plug is resistant to high temperatures, corrosion-resistant and abrasion resistance properties are poor and poor sealing,
The resistant to high temperatures and corrosion resistance of plug is improved, but the multi-component alloy co-cementation aseptic technic that the utility model uses is in plug sheet
The anti-corrosion layer finite thickness generated on body can only carry out anti-corrosion protection to plug ontology, can not be easy on sea water filter
The weak structure for generating electrochemical corrosion carries out long-term anti-corrosion protection, and anticorrosion ability is limited, once on plug ontology
Anti-corrosion layer damages it is necessary to replace entire plug, easily causes waste of material, increases the operation and maintenance cost of equipment.
Utility model content
The purpose of this utility model is to overcome defect of the existing technology, and the existing sea water filter of effective solution is released
