Furthermore, the description of the vertical, horizontal, top, bottom, etc. positional relationships in the present utility model merely represents the relative positions of the components and is not an absolute position in any state.

Example 1

A flexible waterproof wall sleeve, as shown in fig. 1, comprising: line 1. The part of the pipeline 1 at the wall body 10 is sleeved with a flange sleeve 2, the outer side wall of the flange sleeve 2 is in contact with the wall body 10, and a distance of 20-40mm is arranged between the inner side wall and the outer side wall of the pipeline 1 according to the specification of the pipeline 1. The outer side wall of the pipeline 1 and the inner side wall of the flange sleeve 2 are connected through two or three or four or other designed number of elastic connecting pieces 13, wherein: one elastic connection 13 is close to the inner wall of the wall body 10, and one elastic connection 13 is close to the outer wall of the wall body 10. The wall 10 is filled with a sealing paste layer 8 at the gap between the pipeline 1 and the flange sleeve 2 to block the gap between the pipeline 1 and the flange sleeve 2. The flange 7 is additionally arranged on the inner wall of the wall body 10 at the gap between the pipeline 1 and the flange sleeve 2, and the flange 7 is detachably and fixedly connected with the flange sleeve 2. A flange gland 4 is fixed on one side of the flange 7 facing the flange sleeve 2, and a sealing ring 3 is filled between the flange gland 4 and an elastic connecting piece 13 close to the inner wall of the wall body 10.

When the flexible waterproof sleeve is used, water sealing is carried out between the flange sleeve 2 embedded into the wall body and the wall body, and a gap between the pipeline 1 and the flange sleeve 2 is sealed from the outer side of the wall body 10 through the sealing paste layer 8. The bearing force between the pipeline 1 and the flange sleeve 2 is mainly borne by the elastic connecting piece 13, so that the gap between the pipeline 1 and the flange sleeve 2 can be filled by using the traditional waterproof sealant, the filling by using structural adhesive is not needed, and the construction cost is obviously reduced. The waterproof requirement of the inner side of the wall body is generally lower than that of the outer side of the wall body, so that the wall body is sealed by the flange and the sealing ring. On the one hand, the structure ensures that the flexible waterproof sleeve has good waterproof performance, and can be detached, replaced and maintained on the sealing ring through the convenient detachability of the flange, and meanwhile, sundries can be cleaned in gaps between the pipeline 1 and the flange sleeve 2 when necessary.

Example 2

Based on the flexible waterproof wall casing according to embodiment 1, as shown in fig. 1, a wing ring 14 is fixedly installed along the radial direction of the flange casing 2 at the central portion of the wall 10 on the outer side wall of the flange casing 2. The wing ring 14 is inserted into the wall body 10, when cracks are gradually generated between the wall body 10 and the flange sleeve 2 due to different thermal expansion coefficients, the wing ring 14 can play a good role in leakage prevention and blocking, so that leakage liquid penetrating into the cracks is blocked at the wing ring 14, and continuous penetration is difficult.

Example 3

Based on the flexible waterproof casing for a wall body according to embodiment 1, as shown in fig. 1, a first platform 201 and a second platform 202 extending outwards are respectively disposed at two ports of the flange casing 2, and an elastic sealing layer is disposed at the first platform 201 on the outer wall of the wall body 10. The inner side wall of the first platform 201 is in pressing contact with the elastic sealing layer, and the inner side wall of the second platform 202 is in pressing contact with the inner wall of the wall body 10. By adding the first platform 201 and the second platform 202 at the end face of the flange sleeve 2, a buckling waterproof surface can be formed, and the water sealing performance between the flange sleeve 2 and the wall body 10 is improved. Since the exterior wall requires higher water tightness, the water tightness is sealed by the added elastic sealing layer, and the water tightness is prevented from being reduced due to the gap between the wall body 10 and the first platform 201.

Example 4

Based on the flexible waterproof casing for a wall according to embodiment 3, as shown in fig. 1, a portion of the first platform 201, which is close to the pipeline 1, is provided with a concave circular truncated cone, and the sealing paste layer 8 is formed into a circular truncated cone and fills the concave circular truncated cone of the first platform 201. This arrangement can form a multi-layer seal between the sealant layer 8 and the first platform 201, and the sealing surface does not protrude from the top of the first platform 201, thus protecting the sealant layer 8.

And flexible joint filling materials are filled between the sealing paste layer 8 and the elastic connecting piece 13 close to the outer wall of the wall body 10. This arrangement may further promote water tightness at the outer wall of the wall 10.

Example 5

Based on the flexible waterproof casing of the wall body according to embodiment 3, as shown in fig. 1, the second platform 202 is provided with a flange pipe sleeve threaded hole, the flange 7 is provided with a flange threaded hole at a position corresponding to the threaded hole, and the stud 5 passes through the flange threaded hole and is screwed and fastened with the flange threaded hole and the flange pipe sleeve threaded hole. The stud 5 is threaded with a nut 6 on the side of the flange 7 facing away from the second platform 202. This arrangement enables a detachable fixed connection between the flange 7 and the flange sleeve 2.

The part of the second platform 202 close to the pipeline 1 is provided with a groove, and the side wall of the flange gland 4 is provided with a plugboard 401 matched with the groove at the groove. This arrangement can form a multi-layer water-tight seal between the flange gland 4 and the second platform 202, improving water tightness.

Example 6

Based on the flexible waterproof casing for a wall of embodiment 1, as shown in fig. 2, the sealing ring 3 includes: a rigid core 301 that mates with line 1. The outer side of the rigid core 301 is wrapped with a rubber layer 302, and the outer side of the rubber layer 302 is wrapped with an elastic waterproof layer 303. The sealing ring 3 adopting the structure can share the bearing capacity of a part of the elastic connecting piece 13 through the rigid core 301 on one hand, and can support the elastic waterproof layer 303 through the rubber layer 302 on the other hand, so that the elastic waterproof layer 303 can be continuously pressed between the pipeline 1 and the flange sleeve 2, and elastic water sealing is realized.

Example 7

The water sealing hose 1304 is fixedly connected at its connection end to the first rigid connection 1301 and the second rigid connection 1302, respectively.

At this time, the compression spring 1303 is used to bear the pressure between the first rigid connection 1301 and the second rigid connection 1302, thereby realizing the bearing of the force between the pipeline 1 and the flange sleeve 2. When vibration occurs, the compression spring 1303 can effectively buffer vibration force, slow down rigid movement between the pipeline 1 and the flange sleeve 2, and protect the pipeline 1 and the flange sleeve 2. The added water sealing hose 1304 can realize auxiliary water sealing at the elastic connecting piece 13, and improves the waterproof sealing performance of the flexible waterproof sleeve.
