Abstract
The invention discloses a duplex blind plate flange. The duplex blind plate flange comprises a flange part, and further comprises a blind plate part and a projection part, wherein the blind plate part is near the flange part; two through holes are formed in the duplex blind plate flange, and are positioned between the flange part and the blind plate part; the projection part is arranged above the flange part and the blind plate part, and is provided with a push-pull groove; the two ends of the push-pull groove respectively extend to the blind plate part and the flange part; and the flange part, the blind plate part and the projection part are molded as a whole. The duplex blind plate flange can realize rotary switchover and push-pull type switchover, and needs a smaller space in operation, so that the space limitation is reduced, and the duplex blind plate flange can be suitable for narrow areas.
Description
Technical field
The present invention relates to a kind of duplex blank flange.
Background technique
Duplex blank flange is part conventional on boats and ships, for the connection between pipe.By adjustment duplex blank flange, can realize switching the switching of pipeline.At present, when needing the switching switching pipeline, need the disassembling bolts on duplex blank flange, therefore, there is the defect using inconvenience in it; In addition, need larger space during switching, therefore, it is not suitable for narrow zone.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the use inconvenience that prior art exists, the defect needing larger switching space, providing a kind of duplex blank flange.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of duplex blank flange, it comprises a flange part, its feature is, described duplex blank flange also comprises a blind plate portion and a bump, described blind plate portion and described flange part adjoin, described duplex blank flange is also provided with two through holes, through hole described in two is between described flange part and described blind plate portion, described bump is located at the top in described flange part and described blind plate portion, described bump is provided with a push/pull slot, the two ends of described push/pull slot extend described blind plate portion and described flange part respectively, described flange part, described blind plate portion and described bump are formed in one.
Preferably, described flange part and described blind plate portion are respectively provided with at least one bolt hole, and the diameter of described through hole is identical with the diameter of described bolt hole.All wear bolt in bolt hole and through hole, this duplex blank flange can be fixed on pipeline, and the diameter of through hole is identical with the diameter of bolt hole, therefore, both can use identical bolt, thus have saved cost.
Preferably, the width of described push/pull slot is identical with the diameter of described bolt hole.All can wear bolt in push/pull slot and bolt hole, this duplex blank flange can be fixed on pipeline, and the width of push/pull slot is identical with the diameter of described bolt hole, therefore, both can use identical bolt, thus have saved cost.
Preferably, the bolt hole in described flange part is two.By two bolts hole, this duplex blank flange stably can be fixed on pipeline.
Preferably, the bolt hole in described blind plate portion is two.By two bolts hole, this duplex blank flange stably can be fixed on pipeline.
Positive progressive effect of the present invention is: marine piping uses duplex blank flange of the present invention, when needing the break-make switching pipeline, mode by rotation or this duplex of push-and-pull blank flange realizes, therefore, duplex blank flange of the present invention can realize rotary type and switch and plug-type switching, during operation, requisite space is less, thus reduces spatial constraints, is applicable to narrow zone.
Accompanying drawing explanation
Fig. 1 is the structural representation of present pre-ferred embodiments.
Fig. 2 is the A-A cross-sectional schematic in Fig. 1.
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the present invention to be described.
As depicted in figs. 1 and 2, a kind of duplex blank flange, it comprises flange part 1, blind plate portion 2 and bump 3, blind plate portion 2 adjoins with flange part 1, and duplex blank flange is also provided with two through holes 4, two through hole 4 is between flange part 1 and blind plate portion 2, bump 3 is located at the top in flange part 1 and blind plate portion 2, bump 3 is provided with push/pull slot 5, and the two ends of push/pull slot 5 extend blind plate portion 2 and flange part 1 respectively, and flange part 1, blind plate portion 2 and bump 3 are formed in one.
Flange part 1 and blind plate portion 2 are respectively provided with two bolts hole 6, and the diameter of through hole 4 is identical with the diameter of bolt hole 6; The width of push/pull slot 5 is identical with the diameter of bolt hole 6.
Marine piping uses duplex blank flange of the present invention, when needing the break-make switching pipeline, can have two kinds of switching modes.
The first switching mode is that rotary type switches.Specifically, in through hole 4, bolt is housed, with arbitrary through hole 4 for rotating center, rotates this duplex blank flange, the switching of duplex blank flange realization to the break-make of pipeline can be made, and action required space is less.
The second switching mode is plug-type switching.Specifically, be provided with bolt in push/pull slot 5, applied thrust on this duplex blank flange, this duplex blank flange can slide along push/pull slot, thus realizes the switching of duplex blank flange to the break-make of pipeline, and action required space is less.
Duplex blank flange of the present invention can realize rotary type and switch and plug-type switching, and during operation, requisite space is less, thus reduces spatial constraints, is applicable to narrow zone.
In describing the invention, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.
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.
