Embodiment one: the clamping apparatus for sealing the leakage flange comprises two sealing sleeves 3 respectively sleeved on the pipelines 2 at two sides of the flange 1, wherein the two sealing sleeves 3 are clamped by a clamping assembly, and the vertical height of a clamping surface of the clamping assembly is higher than the vertical height of the leakage liquid level of the flange 1; the clamping assembly comprises an encircling annular groove 4 integrally formed by the bottom end of the sealing sleeve 3 positioned above and an embedded ring clamp 5 integrally formed by the top end of the sealing sleeve 3 positioned below, and any side of the longitudinal section of the embedded ring clamp 5 is T-shaped. Both sealing sleeves 3 are spliced by a pair of half cylinders 6 to be sleeved on the pipeline 2. The mating surfaces of each half 6 form a right-angled edge 7 and a male-female fit is formed between two opposing right-angled edges 7. The concave-convex matching comprises convex lines 8 and concave lines; the relief 8 and the intaglio are provided on the contact surfaces of the two opposite right-angled edges 7, respectively. The outer surface of the embedded ring clamp 5 is wrapped with a sealing gasket 9, a screw hole 10 is formed in the surrounding ring groove 4, and a screw rod 18 for extruding the embedded ring clamp 5 is arranged in the screw hole 10, so that the sealing gasket 9 forms interference fit between the embedded ring clamp 5 and the surrounding ring groove 4.
The first method for installing the fixture of the embodiment is as follows:

The above-mentioned mounting method, in which the through hole to be established in the center of the top end of the lower sealing sleeve 3 is larger than or equal to the maximum radius of the flange 1, can directly clamp the surrounding ring groove 4 and the insert ring clamp 5.
Obviously, as shown in fig. 1-3, the surrounding ring groove 4 and the insert ring clip 5 cannot be directly clipped under the vertical action, so the second method for installing the clip of the present embodiment is as follows:
the corresponding half cylinders 6 of the upper sealing sleeve 3 and the lower sealing sleeve 3 are installed, the embedded ring clamp 5 can be transversely rotated to be embedded into the surrounding ring groove 4, then the screw 18 is used for screwing into the screw hole 10, the sealing gasket 9 and the embedded ring clamp 5 are extruded through the screw 18, the sealing gasket 9 is extruded between the embedded ring clamp 5 and the surrounding ring groove 4 (thereby forming interference fit), at the moment, the installed half cylinders 6 of the upper sealing sleeve 3 and the installed half cylinders 6 of the lower sealing sleeve 3 are needed to be clamped in the way, at the moment, the installed half cylinders 6 of the upper sealing sleeve 3 and the installed half cylinders 6 of the lower sealing sleeve 3 are placed at the corresponding positions of the flange 1, then the other half cylinders 6 are directly aligned, one person takes charge of aligning and pressing, and the other person directly uses bolts to fold and lock the opposite right-angle edges 7.
The clamping apparatus of this embodiment adopts the way of half a section of thick bamboo 6 to splice upper and lower seal cover 3 first, then connect with corresponding half a section of thick bamboo 6 of upper and lower seal cover 3, then make two half a section of thick bamboo 6 close up and seal in flange 1 department, because the upper and lower seal cover 3 of this invention adopts the way of mechanical connection, therefore upper and lower seal cover 3 can leave a large amount of cavitys around flange 1, in order to adapt to different flange 1 sizes, and the cavity can hold the content that leaks in the partial pipeline 2, thus reduce the influence of the content to the closure of half a section of thick bamboo 6 to a certain extent.
