Description
Technical field
The present invention relates to leakage test plugging engineering device technique field, and in particular to a kind of leakage test plugging device.
Background technology
, it is necessary to carry out leak test experiment after to needing the cavity to form sealed environment to machine, to detect that seal cavity is
It is no to have in the presence of leakage.There is a kind of special-shaped tubular housing of bend pipe structure at present, two ends have opening, and one end processes to form flange
There are multiple bolts hole on attachment structure, flange connection, because the profile of bend pipe structure tubular housing is irregular, processing
Cheng Hou, when carrying out leak test, the problem of there is bad location test.
The content of the invention
In view of the technical drawbacks of the prior art, it is an object of the present invention to provide a kind of bend pipe structure tubular housing
Leakage test plugging device.
To realize that the technical scheme that the purpose of the present invention is used is：
Circle is provided with a kind of leakage test plugging device, including bottom plate, the bottom plate has being used for for annular step surface
To the seal disc of a port location sealing of workpiece, ring-shaped rubber sealing ring, the bottom are installed in the annular step surface
Side is provided with rectangular-shaped sealing plate on plate, is sealed for another flange port to workpiece, adds on the sealing plate
Work formed have on the bolt connection mounting hole of multiple companion flange ports bolt hole, the inner seal face of the sealing plate with pair
The sealing ring for the bolt connecting hole answered, the middle part of the sealing plate is introduced provided with high-pressure medium also to be passed through on interface, the bottom plate
Clamping screw is provided with pressing plate, for workpiece to be pressed on into the bottom plate from top after workpiece is positioned.
It is hickey that the high-pressure medium, which introduces interface,.
The seal disc is bolted with the bottom plate, and the bottom of the clamping screw connects with the base thread
Connect, top through after the screw hole on the pressing plate by nut check.
Leakage test plugging device of the present invention, by setting seal disc and sealing plate on bottom plate, and by sealing ring and
Ring-shaped rubber sealing ring makes after two port sealings connection of workpiece, passes through high-pressure medium and introduces interface introducing gases at high pressure or liquid
Body squeezes into the inside cavity of workpiece, you can realize leak test operation by external observation.

Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
As Figure 1-4, circle is provided with a kind of leakage test plugging device, including bottom plate 1, the bottom plate has annular
Installed in the seal disc 2 for being used for the location sealing of port 14 to a bottom of workpiece 10 of step surface, the annular step surface
There is side on ring-shaped rubber sealing ring 3, the bottom plate to be provided with a rectangular-shaped sealing plate 7 vertically, for another to workpiece
Flange port 11 is sealed, and processing forms the bolt connection mounting hole of multiple companion flange ports bolt hole on the sealing plate
71, there are the sealing ring 8 with corresponding bolt connecting hole 80, the middle part of the sealing plate on the inner seal face of the sealing plate
Introduced provided with high-pressure medium on interface 70, the bottom plate and pressing plate 4 is also provided with by clamping screw 6, for after workpiece is positioned
Workpiece 10 is pressed on the bottom plate from top.
Wherein, it is hickey that the high-pressure medium, which introduces interface, and connection high-pressure medium introduces joint 9.In the sealing
On plate with 11 pairs of another flange port of the sealing ring 8 and workpiece it is good after, the two is connected by multiple bolts 12
It is tightly connected to realize
Wherein, the seal disc 3 is connected with the bottom plate by being located at the bolt 13 of circle centre position, the clamping screw 6
Bottom is threadedly coupled with the bottom plate 1, top through after the screw hole on the pressing plate 4 by nut check.
Specifically, the clamping screw be two, respectively correspond to be arranged on bottom plate on, and with two screw holes on pressing plate
41st, 42 coordinate, tight in outer side chain by nut from after the stretching of described two screw holes 41,42.
Wherein, the sealing plate is placed directly on the bottom plate, it is not necessary to be fixed with bottom plate.
It is of the invention to make use of the flange connection surface of workpiece in itself well, the leakage test to workpiece is realized, it is convenient to operate,
And good airproof performance, test effect is notable.
Leakage test plugging device of the present invention, by setting seal disc and sealing plate on bottom plate, and by sealing ring and
Ring-shaped rubber sealing ring makes after two port sealings connection of workpiece, passes through high-pressure medium and introduces interface introducing gases at high pressure or liquid
Body squeezes into the inside cavity of workpiece, you can realize leak test operation by external observation.
Described above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
