Side is detachably connected by engaging lug fitted bolt part；Protective case after the upper protective case and lower protective case assembly includes two
The fixed plate of side and the cydariform coaming plate for connecting both sides fixed plate, fixed plate are circular slab, cydariform coaming plate by both sides to centre by
It is gradually outwardly；The maximum inner diameter D1 of the cydariform coaming plate is more than flange outer diameter D2；Fixing hole is provided among the fixed plate, Gu
The interior edge for determining hole is provided with retainer plate made of elastomeric material；The internal diameter D3 of the fixing hole is more than outer diameter tube D4, and retainer plate is just
The internal diameter D5 of normal state is less than outer diameter tube D4；The cydariform coaming plate, fixed plate, fixing hole, retainer plate by upper protective case and
Lower protective case is divided equally.
The retainer plate includes being fixed on the fixing end on fixing hole and the connection end with tube fit, connection end inner side
Curve inwardly to form U-shape structure.
Sealing strip is equipped with the respective mating surface of the upper protective case and lower protective case junction.
Any side cydariform coaming plate of the protective case is provided with detection mouth, and detection mouth is provided with and planted inside protective case
Pressure gauge.
Above-mentioned technical proposal is employed, the utility model has following beneficial effect：(1) the utility model is included up and down
Symmetrically arranged upper protective case and lower protective case, not only mounting flange protective case simultaneously can be installed in pipeline, can also be directed to existing
There is the flange in pipeline to carry out later stage installation, good airproof performance simple to operate, there are wide market prospects.
(2) curve inwardly to form U-shape structure on the inside of the connection end of the utility model retainer plate, shape when coordinating with pipe surface
Change direction with its original bending direction always, better tightness, service life is longer.
(3) any side cydariform coaming plate of the utility model protective case is provided with detection mouth, detection mouth be provided with plant into
Pressure gauge inside protective case, it is convenient for people to intuitively check flange leakage situation when checking.
Brief description of the drawings
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model, wherein
Fig. 1 is structural representation of the present utility model.
Fig. 2 is internal structure schematic diagram of the present utility model.
Fig. 3 is the utility model box flange mating connection schematic diagram.
Embodiment
(embodiment 1)
As shown in Fig. 1 to Fig. 3, the flange leakage protective case of the present embodiment, protective case is drum organization, including symmetrical above and below
The upper protective case 1 and lower protective case 2, upper protective case 1 and the lower side of protective case 2 set is hinged by hinge, and opposite side passes through company
Lug fitted bolt part is detachably connected.
Protective case after upper protective case 1 and the lower assembly of protective case 2 includes the fixed plate 3 and connection both sides fixed plate of both sides
3 cydariform coaming plate 4, fixed plate 3 are circular slab, and cydariform coaming plate 4 is gradually outwardly by both sides to centre.Cydariform coaming plate 4 is most
Large diameter D1 is more than flange outer diameter D2.Fixing hole 3-1 is provided among fixed plate 3, fixing hole 3-1 interior edge is provided with elastomeric material system
Into retainer plate 5.Fixing hole 3-1 internal diameter D3 is more than outer diameter tube D4, and the internal diameter D5 of the normal condition of retainer plate 5 is less than outside pipeline
Footpath D4.Cydariform coaming plate 4, fixed plate 3, fixing hole 3-1, retainer plate 5 are divided equally by upper protective case 1 and lower protective case 2.Retainer plate 5
It is inwardly curved on the inside of connection end 5-2 including the fixing end 5-1 being fixed on fixing hole 3-1 and with tube fit, connection end 5-2
It is curved into U-shape structure.Sealing strip is equipped with the respective mating surface of upper protective case 1 and the lower junction of protective case 2.Protective case is appointed
