Description

Technical Field

[0001] The present application relates to the technical field of washers, and in particular to an anti-disassembly and drop-off washer. Background Art

[0002] During the pipeline installation process, it is usually necessary to add gaskets between the connected flanges. The gaskets are used to increase the sealing between the flanges, and the materials used are also better than ordinary flanges.

[0003] However, in some experimental pipelines, the pipelines need to be disassembled many times. When the pipelines are disassembled, the sealing ring loses the support of the pipeline and falls to the ground, causing deformation and wear. The damaged sealing ring loses its sealing effect and cannot be used again. In response to the above-mentioned related technologies, the applicant has proposed a gasket that can prevent it from falling after disassembly, so that the gasket can be reused many times. Utility Model Content

[0009] By adopting the above technical solution, although the separation structure increases the complexity of the gasket, the gasket can be easily installed and disassembled by using specific tools through the reasonable design of the separation box and the lifting column size, as well as the appropriate elastic force of the separation spring, which ensures both safety and operational convenience; through the sliding connection between the lifting column and the separation box, and the elastic drive of the separation spring, the contact surface between the gasket and the flange is adaptively adjusted.

[0018] Although the separation structure increases the complexity of the gasket, the reasonable design of the separation box and the lifting column size, as well as the appropriate elastic force of the separation spring, make it easy to install and remove the gasket with specific tools, which not only ensures safety but also takes into account the convenience of operation; the sliding connection between the lifting column and the separation box, as well as the elastic drive of the separation spring, realizes the adaptive adjustment of the contact surface between the gasket and the flange. This design can prevent unevenness caused by tolerance, ensure close contact between the gasket and the flange, and enhance the sealing effect;

[0019] By controlling the rotation of the bolt, it is possible to switch between the two positions, thus achieving precise control of the position of the magnetic stone. When the control bolt is located close to the lifting column, the magnetic stone is connected to the plug-in channel through the connecting channel, which facilitates the installation of the magnetic stone.

[0027] Reference Figure 2 , 3 The outer ring of the gasket body 1 is fixed with a skirt 3 extending outward, and the separation box 21 is fixed to the skirt 3 respectively. The skirt 3 can disperse the stress of the separation spring 23, so that the gasket has good sealing when the connection state is maintained; when one side of the flange is disassembled, the separation spring 23 drives the lifting column 22 to push the corresponding side flange to separate to prevent adhesion, while the other side of the flange is kept connected by the magnetic adsorption structure 4 on the gasket body 1 to prevent falling.

[0028] Reference Figure 2 , 3 The magnetic adsorption structure 4 includes a magnetic stone 42 and a plug-in channel 41. The plug-in channel 41 is opened on the end wall of the separation box 21 on the side opposite to the gasket body 1, and the plug-in channel 41 is arranged close to the flange end wall away from the lifting column 22. The plug-in channel 41 is connected to the outside of the flange, thereby avoiding affecting the sealing of the gasket body 1; the magnetic stone 42 is penetrated and accommodated in the plug-in channel 41, and the magnetic stone 42 is positioned in the separation box 21 through the limit control structure 6 on the inner side of the plug-in channel 41.

[0029] Reference Figure 2 , 3The limit control structure 6 includes a control bolt 61, a connecting channel 62 and a positioning step 63. The control bolt 61 is screwed to the side wall of the separation box 21 opposite to the lifting column 22; the positioning step 63 is fixed to the bolt hole of the separation box 21 corresponding to the control bolt 61; the connecting channel 62 is opened on the side wall of the control bolt 61; when the control bolt 61 is located on the side close to the lifting column 22, the connecting channel 62 is connected to the plug-in channel 41, and the magnetic stone 42 is accommodated in the connecting channel 62; when the control bolt 61 is located on the side away from the lifting column 22, the control bolt 61 abuts against the positioning step 63, and the end wall of the control bolt 61 is flush with the side wall of the separation box 21; a screwdriver hole 7 is opened on the end wall of the control bolt 61 close to the positioning step 63, which is convenient for rotating the control screw.

[0030] Reference Figure 3 , 4 The magnetically attracted gasket body 1 can be easily separated by the prying ear structure 5. The prying ear structure 5 includes a seesaw 51 and a protective plate 52. The seesaw 51 is accommodated in the side wall of the separation box 21 corresponding to the lifting column 22, and the seesaw 51 is fixed to the penetration end of the lifting column 22; when the lifting column 22 is penetrated outside the separation box 21, a gap is left between the seesaw 51 and the separation box 21; the protective plate 52 is penetrated and slidably connected to the separation box 21, and the protective plate 52 is fixed to the seesaw 51 and is located on the outside of the separation spring 23 to prevent the separation spring 23 from being damaged during prying.

[0031] The working process of the present application is: rotate the control screw to the side away from the positioning step 63, at this time the connecting channel 62 is connected with the plug-in channel 41, insert the magnetic stone 42 into the connecting channel 62, and then rotate the control screw to the side close to the positioning step 63, at this time the connecting channel 62 and the plug-in channel 41 are misaligned, the magnetic stone 42 is positioned in the control screw, and at the same time the side wall of the control screw is flush with the separation box 21, the magnetic stone 42 can effectively exert magnetic force.

[0032] The side of the gasket body 1 with the positioning step 63 is installed on the flange, and the magnetic stone 42 assists in adsorption to facilitate installation. The flange on the other side is installed on the gasket body 1. The lifting column 22 is squeezed and accommodated in the separation box 21 to enter the standby state.

[0033] When the flange needs to be disassembled, the flanges on both sides are separated, and the lifting column 22 protrudes from the separation box 21, generating a force to separate the flange on the side close to the lifting column 22 from the gasket body 1, and the magnetic stone 42 is adsorbed on the gasket body 1 on the other side, so that the gasket body 1 will not fall off during the flange separation process. At this time, the seesaw 51 is penetrated by the lifting column 22 on the outside of the separation box 21. By prying the seesaw 51 with the cocking rod, the suction force of the magnetic stone 42 can be easily resisted, thereby separating the gasket body 1 from the flange on the other side, so that the disassembly process of the gasket body 1 is stable and reliable without falling off.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
