Problems solved by technology

However, when the diameter of the drainage pipe or outlet connected to the shunt well is large (such as the diameter of the pipe is above DN400), the diameter of the rubber sleeve cannot be large and the amount of deformation is large. At this time, the end of the rubber sleeve Under large deformation with the end of the outer shell, the end of the rubber sleeve slips out between the flange and the end of the outer shell, and the seal of the charging chamber is not good

Embodiment 1

[0032] see Figure 1 to Figure 9 As shown, the present invention provides a shut-off device, including a rubber sleeve 1, the rubber sleeve 1 is provided with a through flow channel 10, and three or four independent pressure chambers 11 are arranged in the inner circumference of the rubber sleeve 1. In the example, the rubber sleeve 1 is cylindrical, and the cross-sectional shape of the rubber sleeve 1 is circular, and the rubber sleeve 1 at the position of each pressure chamber 11 has an outer rubber layer 12 and an inner rubber layer 13, and The outer rubber layer 12, the inner rubber layer 13 and the rubber sleeve 1 outside the pressure chamber 11 are in an integrated structure; the outer rubber layer 12 of each pressure chamber 1 is provided with an inlet and outlet hole 14, and the inlet and outlet holes 14 and The pressurized chamber 11 is communicated, and the inlet and outlet holes 14 can be two holes of the inlet hole and the outlet hole arranged on the outer rubber l...

Embodiment 2

[0038] see Figure 9 As shown, this embodiment also provides a pipeline with a shut-off device, including:

[0039] The intercepting device in this embodiment, the intercepting device includes a rubber sleeve 1;

[0040] Gland 4, one end of the rubber sleeve 1 is provided with a circumferentially outward raised edge, the other end of the rubber sleeve 1 is installed in the pipe, and the outer wall of the rubber sleeve 1 is attached to the inner wall of the pipe, and the raised edge passes through the The gland 4 is fitted and fixed around the pipe port. During installation, the rubber sleeve 1 is inserted into the pipe from the pipe port, and the raised edge of the rubber sleeve 1 is fixed around the pipe port by the gland 4 and bolts. Easy to install and disassemble. The rubber sleeve 1 is fixed in the pipe through the gland, which cancels the structure of the traditional steel outer cover and reduces the weight of the whole product. At the same time, due to the removal of ...

Embodiment 3

[0046] This embodiment also provides a method for using the intercepting device, as follows:

[0047] Install the shut-off device with four independent pressurized chambers 11 in the pipeline in Example 1. In the installed state, two pressurized chambers 11 are located in the lower half of the pipeline, and the other two pressurized chambers 11 are located in the upper half of the pipeline. The device includes Cut-off state and cut-off state, choose the following cut-off state or cut-off state according to the use requirements:

[0048] At the same time, fill the two pressure chambers 11 located in the lower half with a certain pressure medium until the inner rubber layers of the two pressure chambers 11 are bonded together, and the inner rubber layer 13 of the two pressure chambers 111 deforms upwards to have a certain flow rate Highly see Figure 4 As shown, the flow passage 10 is in a shut-off state;

[0049] All the pressure chambers of the simple shut-off device are con...

Abstract

The invention discloses an intercepting device and a use method, and a pipeline for installing the intercepting device. The intercepting device comprises a rubber sleeve, wherein the rubber sleeve isprovided with a circulating channel in a penetrating mode, the intercepting device is characterized in that three or four independent pressure filling cavities are formed in the rubber sleeve and arearranged at intervals along the circumferential direction of the rubber sleeve, the position, each pressure filling cavity is located, of the rubber sleeve is provided with an outer rubber layer and an inner rubber layer, the outer rubber layers and the inner rubber layers and the rubber sleeve outside the pressure filling cavities are of an integrated structure, access holes are formed in the outer layer rubber layer of each pressure filling cavity, and the access holes communicate with the pressure filling cavities. According to the intercepting device, the pressure filling cavities are arranged in the rubber sleeve, the whole rubber sleeve is of an integrated structure, and compared with the prior art, the problem of sealing of the pressure cavities is avoided, the structure is simpler,and the installation and use are convenient.

Description

technical field [0001] The invention relates to the technical field of drainage equipment, in particular to an intercepting device, a use method, and a pipe for installing the device. Background technique [0002] The flexible shutoff device is a kind of shutoff facility applied to the water outlet or outlet of the diversion well. Its structure generally includes an outer shell and a rubber sleeve. A pressurized cavity is formed between the outer shell and the rubber sleeve. The end of the rubber sleeve The upper part and the end of the outer shell are sealed and connected by a flange. When the pressurized gas is filled into the pressurized cavity, the rubber sleeve is relatively inwardly deformed, the inner wall of the rubber sleeve is attached, and the circulation channel is closed. However, when the diameter of the drainage pipe or outlet connected to the shunt well is large (such as the pipe diameter is above DN400), the diameter of the rubber sleeve cannot be large and ...
