Description

Technical Field

[0001] The utility model relates to the technical field of connecting flanges, in particular to a vacuum cavity loose sleeve inner welding flange anti-loosening device. Background Art

[0002] Flange connection is an important connection method in pipeline construction. It mainly connects pipes and plays an important role and value. Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively, add flange gaskets between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment already have flange plates, which also belong to flange connection.

[0003] When installing the existing connecting flange and pipeline, the pipeline is usually extended into the inner diameter of the flange, and the flange and the pipeline are welded with an electric welder. When the pipeline is damaged, since the flange and the pipeline are welded together, the pipeline cannot be disassembled separately. Therefore, when the pipeline is damaged, the pipeline and the flange need to be replaced as a whole. This greatly increases the replacement cost and reduces the practicality of the device. Therefore, a vacuum chamber loose sleeve inner welding flange anti-loosening device is provided to solve the above problems. Utility Model Content

[0005] When installing the pipe flange and the pipeline, the pipeline is usually inserted into the inner diameter of the flange, and the flange and the pipeline are welded with an electric welder. When the pipeline is damaged, since the flange and the pipeline are welded together, the pipeline cannot be disassembled separately. Therefore, when the pipeline is damaged, the pipeline and the flange need to be replaced as a whole. This greatly increases the replacement cost and reduces the practicality of the device.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A vacuum chamber loose sleeve internal welding flange anti-loosening device comprises a connecting sleeve, one side of the connecting sleeve is fixedly connected to a connecting pipe flange body, a pipeline is provided inside the connecting sleeve, the outside of the pipeline is fixedly connected to a fixing ring, a T-shaped groove is symmetrically provided inside the fixing ring, a T-shaped slider is slidably connected inside the T-shaped groove, the outside of the T-shaped slider is rotatably connected to a rotating cylinder, a connecting ring is fixedly connected to the outside of the connecting sleeve, and the connecting ring is threadedly connected to the rotating cylinder, a sliding push block drives the slide plate to squeeze the T-shaped slider to move, and the T-shaped slider drives the clamping block to move out of the inside of the clamping groove, thereby the rotating cylinder can be rotated in the opposite direction to separate the rotating cylinder from the connecting ring, and the rotating cylinder can be disassembled separately when the pipeline is damaged.

[0008] Preferably, a sealing gasket is fixedly connected to the interior of the rotating cylinder so that the sealing gasket is pressed tightly against the connecting sleeve, thereby increasing the sealing performance of the connection between the connecting sleeve and the pipeline.

[0009] Preferably, a T-shaped limit groove is provided inside the rotating cylinder, and a T-shaped limit block is symmetrically slidably connected inside the T-shaped limit groove. The T-shaped limit block is fixedly connected to the T-shaped slider, which is convenient for limiting the rotating cylinder and preventing the rotating cylinder from shifting during movement.

[0010] Preferably, one side of the T-shaped slider is fixedly connected to a blocking block, and the other side of the T-shaped slider is fixedly connected to a telescopic spring. The interior of the fixed ring is equidistantly provided with blocking slots for use with the blocking block. The T-shaped slider pushes the blocking block into the interior of the blocking slot under the elastic force of the telescopic spring to prevent the rotating cylinder from rotating in the opposite direction during use of the device.

[0011] Preferably, a placement groove is provided inside the T-shaped slider, and a slide is slidably connected inside the placement groove. The slide squeezes the T-shaped slider to move, and the T-shaped slider drives the card block to move out of the slot.

[0013] The utility model provides a vacuum chamber loose sleeve inner welding flange anti-loosening device. Compared with the existing technology, it has the following advantages:

[0014] The vacuum chamber has a detachable pipe flange. Through the arrangement of the connecting ring and the rotating cylinder, the slide can be pulled to squeeze the T-shaped slider to move. The T-shaped slider drives the clamping block to move out of the inside of the clamping groove, and the rotating cylinder can be rotated to separate the rotating cylinder from the connecting ring. When the pipeline is damaged, it can be disassembled separately, reducing replacement costs and improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Furthermore, a sealing gasket 6 is fixedly connected to the interior of the rotating cylinder 5 so that the sealing gasket 6 is pressed tightly against the connecting sleeve 1 , thereby increasing the sealing performance of the connection between the connecting sleeve 1 and the pipeline 9 .

[0023] Furthermore, a T-shaped limit groove 7 is opened inside the rotating cylinder 5, and a T-shaped limit block 10 is symmetrically slidably connected inside the T-shaped limit groove 7. The T-shaped limit block 10 is fixedly connected to the T-shaped slider 8, which is convenient for limiting the rotating cylinder 5 and preventing the rotating cylinder 5 from shifting during movement.

[0024] Furthermore, a block 16 is fixedly connected to one side of the T-shaped slider 8, and a telescopic spring 17 is fixedly connected to the other side of the T-shaped slider 8. The interior of the fixed ring 3 is equidistantly provided with card slots 12 for use with the block 16. Under the elastic force of the telescopic spring 17, the T-shaped slider 8 pushes the block 16 into the interior of the card slot 12 to prevent the rotating cylinder 5 from rotating in the opposite direction during use.

[0025] Furthermore, a placement groove 15 is opened inside the T-shaped slider 8, and a slide plate 14 is slidably connected inside the placement groove 15. The slide plate 14 squeezes the T-shaped slider 8 to move, and the T-shaped slider 8 drives the block 16 to move out from the inside of the slot 12.

[0027] When the pipe 9 and the connecting sleeve 1 are installed, the pipe 9 is pushed into the connecting sleeve 1 and the sliding rotating cylinder 5 moves in the direction of the connecting ring 4. At the same time, the rotating cylinder 5 drives the T-shaped slider 8 to slide inside the T-shaped slide groove 11 through the T-shaped limit block 10, and the rotating cylinder 5 is threadedly connected with the connecting ring 4, so that the sealing gasket 6 and the connecting sleeve 1 are tightly pressed, increasing the sealing effect of the connection between the connecting sleeve 1 and the pipe 9. At the same time, the T-shaped slider 8 pushes the blocking block 16 into the inside of the blocking groove 12 under the elastic force of the telescopic spring 17 to prevent the rotating cylinder 5 from rotating in the opposite direction during use, thereby increasing the stability of the connection between the connecting sleeve 1 and the pipe 9. When the pipe 9 and the connecting sleeve 1 are disassembled, the sliding push block 13 drives the slide plate 14 to squeeze the T-shaped slider 8 to move, and the T-slider 8 drives the blocking block 16 to move out of the inside of the blocking groove 12. As a result, the rotating cylinder 5 can be rotated in the opposite direction to separate the rotating cylinder 5 from the connecting ring 4, which can be disassembled separately when the pipe 9 is damaged, reducing the replacement cost and improving the practicality of the device.
