Abstract
The invention discloses a sacrifice flange for a sea water system, which comprises a hollow cylindrical flange body, wherein the end surface of the flange body is uniformly distributed with a plurality of bolt holes; and the outer wall surface of the flange body is provided with an open hole in the radial direction. The sacrifice flange has controllable leakage points. The thickness of the thinnest wall of the sacrifice flange is greater than the wall thickness of the sacrifice stub pipe in the prior art; and thus, the sacrifice flange has longer service life, and is convenient for installation and replacement.
Description
Technical field
The present invention relates to a kind of sacrifice flange for sea water service system.
Background technique
In the process of vessel motion, the heat major part that equipment produces finally is taken away by seawater by heat exchange, sea water service system is as the main body of boats and ships heat exchange, moment is all in operation, but corrosive properly is stronger, therefore seawaterline and the equipment that is connected with pipeline all become the severely afflicated area of corrosion, after being delivered for use according to boats and ships, the quality guarantee list of pipe-line system gathers, major part is corrosion of piping, also there is the vestige of corrosion in the equipment interface of part simultaneously, even if employ epoxy paint, the advanced measure such as internal plastic coating processes pipeline internal surface, seawater still cannot be stoped the corrosion of pipeline and equipment.In this case, sacrificial anode is used to protect into unique mode sea water service system.
At present, in the anode loss protection of sea water service system, comparatively conventional is use to sacrifice short tube, arrange in the position of pipeline and equipment connection exactly and a bit ofly do not make any surface-treated pipe, utilize this pipe as anode to protect pipeline and equipment, but described sacrifice short tube exists following problem: tube wall thickness is identical, be difficult to detect the leakage point of pipe, namely leakage point is uncontrollable; And tube wall is relatively thin, the very short time will be corroded out leak point, needs frequently to change, waste material.
Summary of the invention
The technical problem to be solved in the present invention is the uncontrollable defect of sacrifice short tube leakage point in order to overcome prior art, provides a kind of sacrifice flange for sea water service system.
The present invention solves above-mentioned technical problem by following technical proposals:
For a sacrifice flange for sea water service system, its feature is, described sacrifice flange comprises the flange body of hollow cylindrical, and the end face of described flange body is uniformly distributed some bolts hole, and the outer wall of described flange body is radially provided with a perforate.
In this programme, aperture bottom is the place that whole sacrifice flange wall is the thinnest to the thickness of flange body internal face, in actual application, also be the part that sacrifice flange corrodes at first, as long as therefore whether the bottom detecting described perforate has seawater to leak, just can know whether described sacrifice flange is corroded, thus learn the need of replacement.
Preferably, described perforate is arranged between adjacent two described bolts hole.
Preferably, bottom to the thickness of internal face of described flange body of described perforate is greater than 13mm.Described thickness is greater than in prior art the wall thickness of sacrificing short tube, therefore longer service life of the present invention.
Preferably, described sacrifice flange also comprises a screw, and a described screw part is embedded in described perforate, the exposed outer wall in described flange body of another part.
Sacrificing when flange is protected sea water service system as anode needs external wire to be connected with hull, between sacrifice flange and equipment, form a current loop.Wire can directly be welded in sacrifices on flange, but is not easy to like this change, therefore in this programme, arranges a screw in perforate, and wire can directly be entangled on screw, facilitates the installation and replacing of sacrificing flange.The screw thread matched with described screw can be set in described perforated wall, screw be fixed on and sacrifice on flange.
Preferably, the edge of the end face of described flange body is provided with groove, and described groove is for placing seal ring.Sacrificing flange for connecting pipeline in sea water service system and equipment, seal ring being set in the groove of sacrificing flange, serving better sealing effect.
Positive progressive effect of the present invention is: the present invention, owing to being provided with perforate on sacrifice flange, makes leakage point controlled; And the most thin-walled of sacrifice flange of the present invention is greater than the wall thickness of sacrifice short tube of the prior art, namely aperture bottom is greater than the thickness of sacrifice short tube of the prior art to the thickness of sacrificing flange inner wall face, adds the working life of sacrificing flange; In addition, screw be arranged so that the present invention be convenient to install and change.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the sacrifice flange for sea water service system of the embodiment of the present invention 1;
Fig. 2 is the sectional structure schematic diagram of A-A in Fig. 1;
Fig. 3 is the schematic diagram of the sacrifice flange for sea water service system of the embodiment of the present invention 2.
Embodiment
Mode below by embodiment further illustrates the present invention, but does not therefore limit the present invention among described scope of embodiments.
Embodiment 1
Fig. 1-2 shows a kind of sacrifice flange for sea water service system, and described sacrifice flange comprises the flange body 1 of hollow cylindrical, and the end face of flange body 1 is uniformly distributed some bolts hole 12, and the outer wall of flange body 1 is radially provided with a perforate 13.Preferably, perforate 13 is arranged between adjacent two bolts hole 12.The edge of the end face of flange body 1 is provided with groove 14, and groove 14 is for placing seal ring.
When sacrifice flange is protected sea water service system as sacrificial anode, first sacrifice flange is installed between equipment and pipeline, and sacrifices flange and be respectively equipped with seal ring between equipment and pipeline.After installing, on sacrifice flange, external wire is connected with hull, and wire can be welded on sacrifices on flange, also can be other modes, to form a current loop between sacrifice flange and equipment.Because, bottom perforate 13 to the thickness h of flange body 1 internal face be the place that whole sacrifice flange wall is the thinnest, in actual application, also be the part that sacrifice flange corrodes at first, as long as therefore whether the bottom detecting described perforate 13 has seawater to leak, just can know whether described sacrifice flange is corroded, if detect, perforate 13 place leaks, and needs to change in time to sacrifice flange.
In the present embodiment, the bottom of perforate 13 is greater than 13mm to the thickness h of the internal face of flange body 1.Described thickness h is greater than in prior art the wall thickness of sacrificing short tube, therefore longer service life of the present invention.
Embodiment 2
Embodiment 2 is substantially the same manner as Example 1, and as shown in Figure 3, difference is that sacrificing flange also comprises a screw 15, and screw 15 part is embedded in described perforate 13, the exposed outer wall in flange body 1 of another part.Wire is directly welded in the mode of sacrificing on flange, be not easy to install and change sacrifice flange, therefore in the present embodiment, arrange a screw 15 in perforate 13, wire can directly be entangled on screw 15, facilitates the installation and replacing of sacrificing flange.The screw thread matched with described screw 15 can be set in described perforated wall, screw 15 be fixed on and sacrifice on flange.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that this only illustrates, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection scope of the present invention.
