Abstract
This utility model relates to Nuclear Instrument technical field, is specifically related to a kind of non-explosion-proof ring flange of nuclear density meter.It includes the disk body of annular, the inner side of described disk body forms the installing hole being stepped that outer diameter is big and the inner diameter is little, peripherally disposed on described disk body have several connecting holes, and on the inner side end of described disk body, depression is provided with the annular groove that can house sealing ring.This utility model quickly can realize fitting tightly with non-explosion-proof detector shell adpting flange, and after bonded to each other, have an annular groove that can put sealing ring, not only can function well as cushioning effect, make between metal covering the tightst, and waterproof effect can be functioned well as, structure design advantages of simple, convenience quick for installation.
Description
Technical field
This utility model relates to radioprotective field of instrumentation technology, is specifically related to a kind of non-explosion-proof ring flange of nuclear density meter.
Background technology
Nuclear level gauge is made up of three parts: transmitter unit, detector cells, radioactive source and carrying shield.Detector cells
Mainly it is made up of shell, sodium iodide crystal, photomultiplier tube, preamplification board and aviation socket etc..
The non-explosion-proof detector of nuclear density meter is applied to general occasion, have to expire when explosion-proof detector shell and Flange joint
Sufficient certain industrial grade requires and field erected convenient and swift property.
Utility model content
Technical problem to be solved in the utility model is to provide that one is completely embedded reliably, shock-absorbing capacity is good and meets anti-
The non-explosion-proof ring flange of nuclear density meter of water class requirement.
For realizing above-mentioned technical purpose, the technical scheme that this utility model employing is following:
The non-explosion-proof ring flange of nuclear density meter, including the disk body of annular, it is big and interior that the inner side of described disk body forms outer diameter
The installing hole being stepped that end diameter is little, peripherally disposed on described disk body have several connecting holes, described disk body
On inner side end, depression is provided with the annular groove that can house sealing ring.
As preferably, the end face outside of described disk body is positioned at the peripheral region of described installing hole and stretches out formation convex annular
Edge.
As preferably, the cross section of described annular groove is semicircle.
As preferably, described connecting hole is provided with six and is distributed uniformly and circumferentially.
This utility model has the following beneficial effect: non-explosion-proof detector shell adpting flange and this non-explosion-proof flange
Dish can quickly realize fitting tightly, and bonded to each other after have an annular groove that can put sealing ring, not only can be fine
Play cushioning effect, make between metal covering the tightst, and waterproof effect can be functioned well as, structure sets
Meter advantages of simple, convenience quick for installation.
Accompanying drawing explanation
The following drawings is only intended to, in schematically illustrating this utility model and explaining, not limit model of the present utility model
Enclose.Wherein:
Fig. 1 is the cross-sectional view of this utility model embodiment；
Fig. 2 be this utility model embodiment look up structural representation.
In figure: 1-disk body；2-installing hole；3-connecting hole；4-annular groove；5-annular flange flange.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is expanded on further.In the following detailed description, only by saying
Bright mode describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art is permissible
Recognize, in the case of without departing from spirit and scope of the present utility model, can be by various different modes to described
Embodiment is modified.Therefore, accompanying drawing and description are inherently protection that is the most illustrative rather than that be used for limiting claim
Scope.
As depicted in figs. 1 and 2, the non-explosion-proof ring flange of nuclear density meter, including the disk body 1 of annular, the inner side shape of described disk body 1
Becoming outer diameter big and the little installing hole 2 being stepped of inner diameter, peripherally disposed on described disk body 1 have several
Connecting hole 3, in the present embodiment, connecting hole 6 is provided with six and is uniformly distributed, in order to install；
On the inner side end of described disk body 1, depression is provided with the annular groove 4 that can house sealing ring；The outside of described disk body 1
End face is positioned at the peripheral region of described installing hole 2 and stretches out formation annular flange flange 5.Employing said structure designs, this non-explosion-proof method
Blue dish can quickly realize fitting tightly with probe body adpting flange, by annular groove 4 and sealing ring, and not only can be very
Play cushioning effect well, make between metal covering the tightst, and waterproof effect can be functioned well as, be beneficial to
Improve water resistance.
Wherein, the cross section of described annular groove 4 is preferably designed as semicircle, the most easy to process, and is easy to place O type
Sealing ring.
The foregoing is only the schematic detailed description of the invention of this utility model, be not limited to model of the present utility model
Enclose.Any those skilled in the art, equivalent done on the premise of without departing from design of the present utility model and principle
Change and amendment, all should belong to the scope of this utility model protection.
