Abstract
The invention provides a protective spacer bush of an iron alloy sacrificial anode for a seawater pipeline. The protective spacer bush mainly and structurally comprises an iron anode protection sleeve and spacer bush seal gaskets, wherein two annular spacer bush seal gaskets are integrally formed with the cylindrical iron anode protection sleeve and are respectively positioned at two ends of the iron anode protection sleeve; water through holes which are regularly arranged are formed in the circumference of the iron anode protection sleeve. The water through holes ensure that the an iron anode is in contact with seawater and a cathode protection function can be brought into full play; because of the protection sleeve, the abrasion of the seawater scouring to the iron anode is alleviated, and the service life of the iron anode is prolonged; when being installed, the protective spacer bush is flatly pinched to directly penetrate through the chamber of the iron anode, and two ends of the protective spacer bush are tightly sealed and adhered to the end surface of a flange through the spacer bush seal gaskets. The protective spacer bush is simple in structure, convenient to install and replace, and capable of effectively solving the problem that the pipeline is blocked as the iron alloy sacrificial anode for the seawater pipeline falls off because of non-uniform dissolution.
Description
Technical field
Invention relates to the protection spacer of ferroalloy sacrificial anode for a kind of seawaterline, is applied to boats and ships and other seawater pipe, belongs to corrosion protection technology field.
Background technology
The seawaterline of boats and ships is important component parts of ship power, fire-fighting and blowdown etc., for the normal operation that guarantees the equipment such as ship's power plant, auxiliary machinery, plays an important role.The piping material that boats and ships are used is mainly copper and copper alloy pipe, and ferroalloy sacrificial anode has unrivaled advantage than other serial sacrificial anodes such as aluminium system, magnesium system and zinc systems aspect protection copper seawater pipe line.But iron anode also exists certain use problem, real ship uses and shows, can produce because autolysis is inhomogeneous and cause bulk to come off, and then cause line clogging, and each system function of boats and ships is had a negative impact.
In view of this technological deficiency, a kind of simple in structure, easy for installation in the urgent need to occurring, be applicable to the use protection spacer of ferroalloy sacrificial anode for seawaterline, can effectively guarantee that iron anode safety brings into play the provide protection to seawater copper alloy pipeline normally.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists; the protection spacer of a kind of seawaterline with ferroalloy sacrificial anode is provided; it does not need complex technology operation that replacing is installed, and can overcome the prior art shortcoming that gasket seal is easily shifted in installation process.
The protection spacer of ferroalloy sacrificial anode for a kind of seawaterline; by elastomeric material processing and fabricating, formed; its agent structure comprises iron anode protective casing and spacer gasket seal; the spacer gasket seal of two annulars and columnar iron anode protective casing are one-body molded and lay respectively at the two ends of iron anode protective casing; the plane of spacer gasket seal is perpendicular to the axis of iron anode protective casing; on the periphery of iron anode protective casing, be provided with permeable hole, permeable hole is equidistantly arranged by ranks order on periphery.
Principle of work: during installation, protection spacer is pinched and flatly directly passed in iron anode chamber, uses bolt that iron anode is connected with two ends seawaterline, the gasket seal at spacer two ends and end face of flange fit tightly rear airtight between iron anode and seawaterline realized; The permeable hole arranging on spacer, guarantees that seawater and iron anode come in contact and give full play to galvanic protection effect; When iron anode produces after block cast, by protective casing, hold the block cast of iron anode, avoid seawaterline to stop up.
Beneficial effect:
1, one-piece construction of the present invention is simple, and it is convenient to install and change, and manufacture and production cost are low simultaneously.
2, protection spacer of the present invention two ends carry integrated caulking gum pad; can not only play the sealing function of original gasket seal; and because itself and protection spacer are structure as a whole and can produce displacement, therefore can overcome that original independent sealed pad easily produces displacement and the defect that causes pipeline leakage.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the partial enlarged drawing of protective casing and sleeve pipe permeable hole.
Fig. 3 is that the present invention installs schematic diagram.
Wherein: 1-iron anode protective casing, 2-permeable hole, 3-spacer gasket seal, 4-iron anode, 5-anode outer tube, 6-bolt, 7-seawaterline
Embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, describe the present invention.
The invention provides the protection spacer of ferroalloy sacrificial anode for a kind of seawaterline; its agent structure comprises iron anode protective casing 1 and spacer gasket seal 3; the spacer gasket seal 3 of two annulars is one-body molded and lay respectively at the two ends of iron anode protective casing 1 with columnar iron anode protective casing 1; on the periphery of the plane of spacer gasket seal 3 perpendicular to the axis iron anode protective casing 1 of iron anode protective casing 1, be provided with permeable hole 2, permeable hole is equidistantly arranged by ranks order on periphery.
The iron anode 4 of selecting according to seawaterline 7 and the dimensioned of supporting flange are made iron anode protective casing 1 and spacer gasket seal 3; iron anode 4 is sleeved in anode outer tube 5; during installation, protection spacer is pinched to the flat cavity through iron anode 4; spacer gasket seal 3 is combined closely with the supporting flange of anode outer tube 5 and seawaterline 7, uses bolt 6 that anode outer tube 5 is tightly connected together with iron anode 4 and two ends seawaterline 7.In seawaterline, 7 pass into Seawater, check pipeline sealing, whether occur seepage.During maintain and replace, only need dismantle the bolt 6 on flange with spanner, old protection spacer is changed.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
