Description

Technical Field

[0001] The utility model relates to an anti-leakage structure, in particular to an inserted flexible interception device reinforced anti-leakage structure, belonging to the technical field of interception and anti-seepage equipment. Background Art

[0002] The flexible interception device is an efficient and environmentally friendly fluid control device, especially suitable for urban drainage systems. The device is controlled by pneumatic components and can flexibly and quickly respond to different fluid environments to achieve clean and dirty separation. The flexible interception device can quickly cut off and divert the fluid through pneumatic control. When sewage enters the interception device, the device will act quickly to intercept the sewage and guide it into the municipal sewage pipe and send it to the sewage treatment plant for treatment. For cleaner rainwater, the device will guide it to the municipal rainwater pipe or directly discharge it into natural water bodies, thereby achieving effective separation of clean and dirty water.

[0003] In the prior art, such as the flexible intercepting device disclosed in the announcement number CN218935352U, the gas passes through the charging nozzle and enters the charging chamber, the inner rubber sleeve gathers under the action of the gas pressure, and the inner rubber sleeve blocks the inner cavity of the intercepting device to achieve interception. When the intercepting device needs to be opened, the gas in the charging chamber is extracted, and the inner rubber sleeve returns to the initial state. The design abandons the traditional way of forming a charging chamber between the outer shell and the rubber sleeve, and innovatively provides an outer rubber sleeve and an inner rubber sleeve. The charging chamber is located between the outer rubber sleeve and the inner rubber sleeve, which greatly improves the overall sealing. However, in actual use, the existing device needs to be connected to the pipeline at both ends, and the hidden plug-in installation of the device cannot be achieved, which will result in a longer length of the assembled pipeline. Secondly, although the existing device also gathers the inner rubber sleeve to form a blockage through the action of gas pressure, in actual blocking, the inner rubber sleeve is tightly together to form a blockage, and cannot form a buckle sealing structure similar to a concave and convex shape, that is, it will cause the liquid to leak easily from the blockage. Utility Model Content

[0004] The purpose of the utility model is to provide an inserted flexible intercepting device with a reinforced anti-leakage structure in order to solve at least one of the above technical problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions: an inserted flexible intercepting device with a reinforced anti-leakage structure, comprising a shell and a rubber sleeve, the rubber sleeve is connected in the shell, an air chamber is provided inside the rubber sleeve, a flow guide cavity is provided at the center of the rubber sleeve, and a reinforced anti-leakage rubber ring is provided in the flow guide cavity of the rubber sleeve;

[0006] One end of the shell is connected with a flange plate, the other end of the shell is connected with a support plate, one end of the rubber sleeve is connected with an air inlet pipe, and the air inlet pipe is communicated with the air chamber.

[0007] As a further solution of the utility model: a concave slot is provided at the front end of the shell, a convex ring is provided on one side of the flange and is clamped in the slot, and the flange and the shell are connected by a plurality of hexagon socket head screws.

[0011] As a further solution of the utility model: a reinforced anti-seepage rubber ring is integrally connected to the middle part of the rubber sleeve.

[0012] The beneficial effects of the utility model are as follows: a rubber sleeve is provided, and an air chamber is opened inside the rubber sleeve. When air is ventilated to the air chamber through the air inlet pipe, the air chamber will expand, so that the inner wall of the rubber sleeve can expand to fit together, forming a blockage for the guide cavity and playing a role of intercepting flow.
