Specific embodiment
For content of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following examples, and coordinate
Accompanying drawing describes in detail as follows：
Refer to Fig. 1～Fig. 3, a kind of tight type flange clamp of shovel, including chuck body 1, described chuck body 1 includes two
Semi-cylindrical shaped portion, two described semi-cylindrical shaped portions are butted into annular solid, and described semi-cylindrical shaped portion inner circumferential is provided with semi-circular boss 3；
Described semi-circular boss 3 embeds between the interface of a pair of flange, the two sides of described semi-circular boss 3 by shovel tight mode with
This fits tightly to the interface of flange, and the top surface of described semi-circular boss 3 is enclosed to the interface of flange with this, constitutes sealing
Cavity.Described semi-circular boss 3 is radially provided with the injecting hole 4 of insertion.For ease of two semi-cylindrical shaped portion docking are fastened,
The radially opposite sides in two described semi-cylindrical shaped portions also can all be respectively equipped with otic placode 2, described otic placode be provided with bolt hole 5 it is also possible to
Other modes are taken to fasten two semi-cylindrical shaped portions.
Flange A6 and flange B9 constitutes a pair of flange, is provided with flange gasket 10, works as flange gasket between flange A6 and flange B9
When piece 10 (sealing gasket) lost efficacy, will leak between flange A6 and flange B9, by two semi-cylindrical shaped parts of chuck body 1
It is not arranged on flange A6 and the flange outer face of flange B9, make semi-circular boss 3 embed the gap between flange A6 and flange B9.
Then bolt is passed through the bolt hole 5 of chuck body 1 both sides otic placode 2 and tighten, semi-circular boss 3 encloses annular boss, with method
The interface of blue A6 and flange B9 is adjacent to, and makes chuck body 1 and the flange pair of leakage flange jointly enclose sealing cavity.
Shovel is implemented sternly to shovel tight position 7 and the tight position of shovel 8 of flange B of flange A.Shovel tight position to refer to, with flange A6 and
The flange corner that the interface of flange B9 is contacted with the semi-circular boss 3 of chuck body 1.Inject sealant in cavity, formed
The seal pressure suitable with leaking medium pressure, terminates leakage.
Further, the axial cross section shape in described semi-cylindrical shaped portion can be infundibulate.Its outer lateral section is rectangle, in
Portion section is trapezoidal, and inner side semi-circular boss 3 section is rectangle, and thickness is less than the minimum clearance amount of flange A6 and flange B9,
It is easy between the flange pair of embedded leakage.
Workflow of the present utility model and operation principle：
(1) on-site land survey is (by GB/T 26467-2011《Bearing device on-line pressure sealant technical specification》Carry out)
1. reconnaissance at criminal scene leakage system interior media pressure, temperature, dielectric property.
2. leakage position physical dimension, completes the determination that fixture semi-circular boss 3 stretches out size and width relative dimensions.
