Description

Technical Field

[0001] The utility model relates to a wall-penetrating waterproof casing. Background Art

[0002] When a pipeline passes through a wall with waterproofing requirements such as a basement or a pool, a waterproof casing is required to protect the pipeline to prevent the pipeline from being damaged and leaking. The existing waterproof casing usually includes a casing, a wing ring, and a pressure cap. Rubber rings are separately arranged on both sides of the inner wall of the casing to seal the inside of the casing. This structure is poor in terms of anti-leakage performance. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a wall-penetrating waterproof casing to improve the sealing performance between the waterproof casing and the pipeline.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wall-penetrating waterproof casing, comprising a flange casing, a wing ring, and a flange pressure cover, the wing ring being welded to the outer diameter surface in the middle of the flange casing, the flange pressure cover being installed at one end of the flange casing by bolts, a first limiting ring being provided on the side of the inner wall of the flange casing close to the flange pressure cover, a rubber ring being provided between the first limiting ring and the flange pressure cover, an annular protrusion being provided on the end of the flange pressure cover facing the rubber ring, the rubber ring and the inner wall of the flange casing forming a space for the annular protrusion to extend into, a gap being provided between the first limiting ring and the inner diameter surface of the flange pressure cover and the pipeline for the rubber ring to deform, and a rubber ring being also installed on the other side of the inner wall of the flange casing.

[0005] As a further improvement of the utility model, the flange sleeve is provided with a second limiting ring arranged at intervals at the installation position relative to the rubber ring, the rubber ring is sleeved on the second limiting ring and extends to the interval between the second limiting rings, and a pressure ring is sleeved on the outward side of the rubber ring.

[0006] As a further improvement of the present invention, a guide surface is provided on a side of the second limiting ring away from the flange cover.

[0007] As a further improvement of the utility model, the wing ring is provided with a plurality of through holes along its radial direction.

[0008] As a further improvement of the utility model, the flange gland is threadedly connected to the inner wall of the flange sleeve.

[0009] The beneficial effects of the utility model are as follows: one side of the waterproof sleeve is screwed into the flange cover to facilitate adjustment of the clamping force on the rubber ring, so that the rubber ring can be tightly pressed on the pipe; the other side improves the sealing performance while preventing the flange sleeve from falling out through the cooperation of the pressure ring, the second limit ring and the rubber ring.

[0013] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0014] Reference Figure 1-2As shown, a wall-penetrating waterproof casing comprises a flange casing 1, a wing ring 2, and a flange gland 3. The wing ring 2 is welded to the outer diameter surface of the middle part of the flange casing 1, and the flange gland 3 is installed at one end of the flange casing 1 by bolts. A first limiting ring 4 is provided on the side of the inner wall of the flange casing 1 close to the flange gland 3, and a rubber ring 5 is provided between the first limiting ring 4 and the flange gland 3. An annular protrusion 6 is provided on one end of the flange gland 3 facing the rubber ring 5, and the rubber ring 5 and the inner wall of the flange casing 1 form a space for the annular protrusion 6 to extend into. A gap is provided between the first limiting ring 4 and the inner diameter surface of the flange gland 3 and the pipe 10 for the rubber ring 5 to deform. The rubber ring 5 is stretched and tightened by the extension of the annular protrusion 6 so that it can fit tightly on the pipe 10. A gap is reserved between the first limiting ring 4 and the flange gland 3 and the pipe 10 so that the rubber ring 5 can extend to the gap to seal after deformation. Usually, the flange gland 3 is fixed separately by bolts, and its bolt installation method needs to be installed one by one from the diagonal bolts, so it is not convenient to pre-tighten the rubber ring 5 conveniently. In this embodiment, the flange The gland 3 is connected to the inner wall of the waterproof sleeve by threads. The length of the threads is controlled to achieve an appropriate pressure to prevent the rubber ring 5 from being in an extreme stress state, resulting in breakage or damage and leakage. A rubber ring 7 is also installed on the other side of the inner wall of the flange sleeve 1. The flange sleeve 1 is provided with a second limiting ring 8 arranged at intervals at a position where the rubber ring 7 is installed. The rubber ring 7 is sleeved on the second limiting ring 8 and extends to the interval between the second limiting rings 8. This arrangement increases the stopping ability of the rubber ring 7, so that the second limiting ring 8 The right-angle surface cooperates with it to prevent it from slipping out of the flange collar. A pressure ring 9 is sleeved on the outward side of the rubber ring 7. The pressure ring 9 is arranged to further lock the rubber ring 7 to improve its sealing performance. A guide surface is provided on the side of the second limiting ring 8 away from the flange gland 3. In addition to facilitating installation, the guide surface can also provide deformation space for the rubber ring 7 when the pipeline 10 is installed, so that the rubber ring 7 and the second limiting ring 8 are more tightly connected. The wing ring 2 is provided with a plurality of through holes along its radial direction, and the through holes are used to connect the steel wire to the on-site formwork for binding and fixing.

[0015] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
