Abstract
The utility model discloses a replacement connector for a ballast tank overflow pipe. An air pipe (4) of a ballast tank is provided with the overflow pipe (3), a standard flange (1) is welded to the tail end of the overflow pipe (3) and connected with a blind flange (2), the outer circumference of the standard flange (1) and the outer circumference of the blind flange (2) are correspondingly provided with four U-shaped slotted holes (5), the standard flange (1) is fixedly connected with the blind flange (2) through bolts installed in the U-shaped slotted holes (5), and the end face of the blind flange (2) is further provided with a handle (6). Due to the fact that one end of every U-shaped slotted hole is open, positioning, installation and dismantling of the bolt are facilitated, the blind flange can be dismantled only by dismantling the four bolts, and dismantling time is reduced. The handle is added to the blind flange, operation by seamen is further facilitated, and working efficiency is improved.
Description
Technical field:
The utility model relates to one and facilitates ballast exchange, is applied to the displacement contact on ballast tank spill pipe.
Background technique:
For guarantee boats and ships in navigation, entering and leaving port, load and unload and the different operating mode such as berth keeps the balance of appropriate water displacement, drinking water, hull vertical and horizontal, to maintain suitable metacentric height, reduce the vibration that the excessive bending moment of hull and shearing force alleviate hull.Need to ballast water be injected to ballast tank or discharge ballast water from ballast tank according to actual conditions.Conventionally the double ballast displacement pipeline that does of ballast tank air duct.In the process of ballast water displacement, need the displacement contact of dismounting ballast tank air duct overflow pipe frequently, displacement contact is in the past round-meshed common flange, fixes by eight bolts.Because the general bore of spill pipe is larger, connecting bolt quantity is more, and you can disassemble blank flange nut need to be screwed down to ability completely, effort again consuming time.
Summary of the invention:
The utility model, for the above-mentioned deficiency of prior art, provides a kind of displacement contact of simple in structure, easy to operate ballast tank spill pipe.
Technical solution of the present utility model is: a kind of displacement contact of ballast tank spill pipe, on the air duct of ballast tank, be provided with spill pipe, end at spill pipe is welded with standard flange, standard flange is connected with blank flange, on the excircle of standard flange and blank flange, correspondence is provided with four U-shaped slotted eyes, standard flange is fixedly connected with by the bolt being placed in U-shaped slotted eye with blank flange, is also provided with handle on the end face of blank flange.
U-shaped slotted eye of the present utility model, due to an end opening, facilitates the location of bolt, and installation and removal, and only to need four bolts of dismounting be detachable blank flange, reduces the take-down time.On blank flange, increase handle, further facilitate crewman's operation, increase work efficiency.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model standard flange.
Fig. 3 is the structural representation of the utility model blank flange.
Embodiment:
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figures 1 to 3, a kind of displacement contact of ballast tank spill pipe, on the air duct 4 of ballast tank, be provided with spill pipe 3, be welded with standard flange 1 at the end of spill pipe 3, standard flange 1 is connected with blank flange 2, on the excircle of standard flange 1 and blank flange 2, correspondence is provided with four U-shaped slotted eyes 5, and standard flange 1 is fixedly connected with by the bolt being placed in U-shaped slotted eye 5 with blank flange 2, is also provided with handle 6 on the end face of blank flange 2.
Standard flange is directly welded on pipeline, zinc-plated processing together with pipeline, and blank flange is made rear zinc-plated processing, and both connect by bolt and nut, can guarantee the requirement of close property, and it are very convenient to remove and install blank flange.
Claims (1)
1. the displacement contact of a ballast tank spill pipe, on the air duct (4) of ballast tank, be provided with spill pipe (3), it is characterized in that: be welded with standard flange (1) at the end of spill pipe (3), standard flange (1) is connected with blank flange (2), on the excircle of standard flange (1) and blank flange (2), correspondence is provided with four U-shaped slotted eyes (5), standard flange (1) is fixedly connected with by the bolt being placed in U-shaped slotted eye (5) with blank flange (2), is also provided with handle (6) on the end face of blank flange (2).
