Description
Technical field
The present invention relates to a kind of sacrifice flange for sea water service system.
Background technology
During vessel motion, the heat that equipment is produced largely finally is taken away by heat exchange by seawater, seawater
System is as the main body of ship heat exchange, and the moment is all in operation, but corrosive properly is stronger, therefore seawaterline and and pipeline
The equipment being connected turns into the severely afflicated area of corrosion, from the point of view of the quality warranty list of pipe-line system collects after being delivered for use according to ship, greatly
Part is corrosion of piping, while the vestige corroded also occurs in partial equipment interface, even with epoxy-based lacquers, internal plastic coating etc. first
Enter measure to handle pipeline inner surface, can not still prevent corrosion of the seawater to pipeline and equipment.In this case, make
Sea water service system is protected with sacrificial anode into unique mode.
At present, in terms of the anode loss protection of sea water service system, more common be using sacrifice short tube, be exactly pipeline with
The position of equipment connection sets a bit of pipe for not doing any surface treatment, protects pipeline by the use of this pipe as anode and sets
It is standby, but there is problems with the sacrifice short tube：Pipe wall thickness is identical, it is difficult to be detected to the leakage point of pipe, i.e.,
Leakage point is uncontrollable；And tube wall is relatively thin, the very short time will be corroded out leak point, it is necessary to frequently change, waste
Material.
The content of the invention
The technical problem to be solved in the present invention be in order to overcome the uncontrollable defect of sacrifice short tube leakage point of prior art,
A kind of sacrifice flange for sea water service system is provided.
The present invention is to solve above-mentioned technical problem by following technical proposals：
A kind of sacrifice flange for sea water service system, its feature is that the sacrifice flange includes the method for hollow cylindrical
Blue body, the end face of the flange body is uniformly distributed some bolts hole, and the flange body outside wall surface radially
Provided with a perforate.
In this programme, aperture bottom to the thickness of flange body internal face be it is whole sacrifice flange wall most thin place,
It is also to sacrifice the part that flange corrodes at first, as long as therefore detecting whether the bottom of the perforate has seawater in actual application
Leakage, just can know that whether the sacrifice flange has been corroded, so as to know whether to need to replace.
It is preferred that the perforate is arranged between the two neighboring bolt hole.
It is preferred that the bottom of the perforate to the thickness of the internal face of the flange body is more than 13mm.The thickness is big
In the wall thickness for sacrificing short tube in the prior art, therefore the service life of the present invention is longer.
It is preferred that the sacrifice flange also includes a screw, the screw part is embedded in the perforate, another part
The exposed outside wall surface in the flange body.
Sacrificing when flange is protected as anode to sea water service system needs external wire to be connected with hull, is sacrificing flange
A current loop is formed between equipment.Wire can be directly welded on sacrifice flange, but is so not easy to change, therefore
In this programme, a screw is set in perforate, and wire directly can be entangled on screw, the installation of sacrificing flange and more is facilitated
Change.The screw thread matched with the screw can be set in the perforated wall, screw is fixed on sacrifice flange.
It is preferred that the edge of the end face of the flange body is provided with groove, the groove is used to place sealing ring.Sacrifice method
Orchid is used to connect the pipeline and equipment in sea water service system, and sealing ring is set in the groove for sacrificing flange, serves preferably close
Seal effect.
The positive effect of the present invention is：The present invention on flange is sacrificed due to being provided with perforate so that leakage point
It is controllable；And the most thin-walled of the sacrifice flange of the present invention is more than the wall thickness of sacrifice short tube of the prior art, i.e. aperture bottom is to sacrificial
The thickness in domestic animal flange inner wall face is more than the thickness of sacrifice short tube of the prior art, adds the service life for sacrificing flange；Separately
Outside, the setting of screw causes the present invention to be easily installed and change.
Brief description of the drawings
Fig. 1 is used for the schematic diagram for sacrificing flange of sea water service system for the embodiment of the present invention 1；
The cross section structure diagram that Fig. 2 is A-A in Fig. 1；
Fig. 3 is used for the schematic diagram for sacrificing flange of sea water service system for the embodiment of the present invention 2.
Embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to described reality
Apply among a scope.
Embodiment 1
Fig. 1-2 shows a kind of sacrifice flange for sea water service system, and the sacrifice flange includes the method for hollow cylindrical
Blue body 1, the end face of flange body 1 is uniformly distributed some bolts hole 12, and the outside wall surface of flange body 1 is radially provided with
One perforate 13.It is preferred that perforate 13 is arranged between two neighboring bolt hole 12.The edge of the end face of flange body 1 is provided with recessed
Groove 14, groove 14 is used to place sealing ring.
When sacrifice flange is protected as sacrificial anode to sea water service system, it will first sacrifice flange and be installed on equipment and pipeline
Between, and it is respectively equipped with sealing ring between sacrifice flange and equipment and pipeline.After installing, the external wire on flange is sacrificed
It is connected with hull, wire can be welded on sacrifice flange or other modes, to sacrifice shape between flange and equipment
Into a current loop.Because the bottom of perforate 13 to the thickness h of the internal face of flange body 1 is that whole sacrifice flange wall is most thin
Place, is also to sacrifice the part corroded at first of flange in actual application, as long as therefore detecting that the bottom of the perforate 13 is
It is no to have seawater leakage, just can know that it is described sacrifice flange whether be corroded, if detect at perforate 13 occur leakage, it is necessary to and
Shi Genghuan sacrifices flange.
In the present embodiment, the thickness h of the internal face of the bottom of perforate 13 to flange body 1 is more than 13mm.The thickness h is big
In the wall thickness for sacrificing short tube in the prior art, therefore the service life of the present invention is longer.
Embodiment 2
Embodiment 2 is substantially the same manner as Example 1, as shown in figure 3, difference is that sacrificing flange also includes a screw
15, the part of screw 15 is embedded in the perforate 13, the exposed outside wall surface in flange body 1 of another part.Wire is directly welded
Mode on flange is sacrificed, is not easy to install and changes sacrifice flange, therefore in the present embodiment, one is set in perforate 13
Screw 15, wire can be directly entangled on screw 15, facilitate the installation and replacing for sacrificing flange.It can be set in the perforated wall
The screw thread matched with the screw 15, screw 15 is fixed on sacrifice flange.
Although the embodiment of the present invention is the foregoing described, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
On the premise of the principle and essence of the present invention, various changes or modifications can be made to these embodiments, but these changes and
Modification each falls within protection scope of the present invention.
