Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure, as the terms used are used to describe particular embodiments only, and are not intended to limit the exemplary embodiments based on the disclosure.

The first embodiment:

fig. 1 shows, the utility model relates to an online leakage elimination device of sediment water pipeline, including all having open-ended cyclic annular clamp 1 and cyclic annular sealed pad 2, clamp 1 with sealed pad 2 sets up with one heart. The sealing gasket 2 is positioned on the inner side of the clamp 1, and the opening of the sealing gasket 2 is opposite to the opening of the clamp 1. As shown in fig. 3, a protrusion 6 extending in the circumferential direction is provided on the outer side of the sealing gasket 2, a sliding groove 7 corresponding to the protrusion 6 and extending in the circumferential direction is provided on the inner side of the

clamp

1, and 2 or 3 protrusions 6 and sliding grooves 7 are uniformly provided in the axial direction. The protrusion 6 and the sliding groove 7 can slide relatively, that is, the sealing gasket 2 and the clamp 1 can rotate relatively. The cross sections of the protrusion 6 and the sliding groove 7 are rectangular.

The opening of the clamp 1 is also provided with a clamping part for fastening the clamp on a pipeline. The clamping part includes by the both ends of the opening part of clamp 1 outwards extend into two parallel stationary blades 3 respectively, two be equipped with corresponding through-hole on the stationary blade 3, pass in proper order with bolt 4 the through-hole, the cooperation rather than assorted nut 5 will clamp 1 fastens up. As shown in fig. 2, a plurality of through holes, and bolts 4 and nuts 5 matched with the through holes are uniformly provided on the two fixing pieces 3 along the axial direction.

The projections 6 of the sealing gasket 2 are first clamped into the sliding grooves 7 of the clamp 1, and the sealing gasket 2 is rotated relative to the clamp 1 so that their openings are in the same direction. When the slag water pipeline seepage, break big with the fingers and thumb clamp 1 and the opening of sealed pad 2 with strength, until the pipeline can pass its opening, overlap clamp 1 and sealed pad 2 on the pipeline, then the sealed pad 2 of rotation makes its opening and the relative setting of clamp 1's opening to sealed pad 2 covers the seepage position at the pipeline completely. The clamp 1 and the sealing gasket 2 are fastened on the pipeline by utilizing the clamping part (namely, the nut 5 on the bolt 4 is screwed), and when the clamp 1 deforms along with the clamping of the clamping part, the sealing gasket 2 can generate corresponding deformation along the sliding groove 7 through the protrusion 6 on the sealing gasket 2, so that when the clamp 1 is clamped on the pipeline by the clamping part, the sealing gasket 2 can tightly block the leakage part on the pipeline, and the online leakage elimination of the pipeline is easily realized.

Second embodiment:

in addition to the first embodiment, as shown in fig. 4, the cross-sectional shapes of the boss 6 and the chute 7 are trapezoidal shapes having a wide outer side and a narrow inner side. When the protrusion 6 is engaged with the sliding groove 7, the gasket 2 can be pulled out from the open end of the clip 1 only to detach the gasket 2 from the clip 1. Therefore, when depositing this device, utilize its arch 6 to rotate along the spout 7 of clamp 1 with sealed 2, make the opening of clamp 1 and sealed 2 of filling up be located same direction, clamp 1 just can form wholly with sealed 2 of filling up, conveniently deposits and takes. Simultaneously, be trapezoidal with the cross sectional shape design of arch 6 and spout 7, can avoid producing radial movement between the sealed pad 2 of hourglass in-process and clamp 1, thereby improved the utility model discloses a stability improves the work efficiency of hourglass.

The third embodiment:

the third embodiment of the present invention differs from the first or second embodiment only in the clamping portion, and the features and structures of the other portions are substantially the same. The difference specifically lies in: fig. 5 shows, the clamping part includes the arc 8 of outside arch 6 the both ends of arc 8 inwards extend and form block claw 9 the mutual symmetry in the both ends outside of clamp 1 open-ended is equipped with a plurality of recesses 10 along circumference evenly distributed, two block claw 9 can block into and be located both ends respectively in the recess 10, and then will clamp 1 fastens. The arc-shaped plate 8 is also provided with a pull ring 11 which can slide along the arc-shaped plate 8. When leakage elimination work is carried out, one clamping claw 9 is clamped into a groove 10 at one end of the opening of the clamp 1, then the pull ring 11 is pulled to the junction position of the other clamping claw 9 and the arc-shaped plate 8 according to the diameter of a pipeline, the other clamping claw 9 is clamped and pulled into a proper groove 10 at the other end of the opening of the clamp 1, and the clamp 1 enables the sealing gasket 2 to be fastened on the pipeline; when the clamping hoop needs to be disassembled, the pull ring 11 is pulled to the junction position of the arc-shaped plate 8 and one of the clamping claws 9, the pull ring 11 is pulled outwards with force, the clamping claws 9 can be pulled out of the grooves 10, and then the arc-shaped plate 8 can be easily separated from the clamping hoop 1. The leakage eliminating device is only used when the pipeline has leakage and has temporary property. Therefore, the installation and the disassembly of the device can be facilitated by the arrangement of the arc-shaped plates 8 of the clamping parts, and the time is saved. The groove 10 is preferably inclined in a direction away from the opening of the clip 1, so that the engagement force between the engagement claw 9 and the groove 10 can be increased, and the engagement claw 9 can be prevented from coming out of the groove 10. Further improved the utility model discloses a stability can, the safety of production process has been guaranteed.

In the description of the present invention, the terms describing the orientation such as "inside" and "outside" are based on the positional relationship shown in the drawings, the position close to the center of the circle of the clip 1 and the gasket 2 is "inside", and the position away from the center of the circle of the clip 1 and the gasket 2 is "outside". The above terminology is for the purpose of simplifying the description of the present invention only and is not to be construed as limiting the present invention.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
