Examples
Referring to fig. 1, the present invention provides a vacuum pipe sealing connection structure, which includes a pipe end assembly 10 and a sealing assembly 20.
Wherein, seal assembly 20 installs the tip at pipeline tip subassembly 10, and when seal assembly 20 adopted traditional packing ring sealing mode, increase the packing ring from inside to outside holding power for the packing ring is difficult not hard up, guarantees that the packing ring has good sealed effect for a long time.
Referring to fig. 1, the pipe end assembly 10 includes a pipe main body 110 and a flange 120, the flange 120 is fixedly installed at an end of the pipe main body 110, and the flange 120 and the pipe main body 110 are fixed by welding; and one side of the flange plate 120, which is far away from the pipeline main body 110, is provided with a mounting groove 121.
Referring to fig. 2 and 3, the sealing assembly 20 includes a sealing gasket 210 and an elastic supporting member 220, wherein one side of the sealing gasket 210 is clamped in the mounting groove 121, and a groove 211 is formed on one side of the sealing gasket 210 close to the pipe body 110. The elastic supporting member 220 includes a telescopic adjusting lever 222 and a spring 221, one end of the telescopic adjusting lever 222 is fixedly connected to the bottom end of the mounting groove 121, the other end of the telescopic adjusting lever 222 is connected to the spring 221, and the end of the spring 221 is disposed inside the groove 211. The sealing washer 210 is provided with annular grooves 212 on the side away from the flange plate 120, and at least three groups of annular grooves 212 are arranged. The vertical section of the annular groove 212 is of an inverted trapezoidal structure. One side of the sealing washer 210 is provided with a through hole corresponding to the mounting hole on the flange plate 120 for fixing and mounting the bolt. The trapezoidal annular groove 212 on the outside of the sealing gasket 210 enables the sealing gasket 210 to have better sealing effect with the port contact surface of the cavity. A sealing ring 230 is arranged at the bottom end inside the mounting groove 121, a through hole 231 is formed in one side of the sealing ring 230, and the elastic supporting member 220 movably penetrates through the through hole 231; the sealing ring 230 is used to increase the elasticity of the sealing gasket 210. The seal ring 230, the flange 120 and the sealing gasket 210 all have the same inner diameter.
Referring to fig. 4, the telescopic adjusting rod 222 includes a screw 224 and a sleeve 223, one end of the screw 224 is fixedly connected to the bottom end of the inside of the mounting groove 121, and the screw 224 is fixed to the mounting groove 121 by welding; and the other end of the screw 224 is screwed into the interior of the sleeve 223, and the end of the sleeve 223 is connected with the spring 221. The inner wall of the sleeve 223 is provided with internal threads 225, and the screw 224 is in threaded fit with the sleeve 223. Turning the sleeve 223 in the telescopic adjuster, the sleeve 223 is also moved laterally while turning outside the screw 224, so that the distance between the spring 221 and the sealing washer 210 is adjusted. One side of the sleeve 223 far away from the screw 224 is provided with a limit groove 226. A limiting block 240 is arranged on one side of the sleeve 223 far away from the screw 224, the limiting block 240 is sleeved inside the spring 221, and one end of the limiting block 240 is inserted inside the limiting groove 226; the limiting block 240 is used for limiting the installation position of the spring 221. The limiting groove 226 is also used for limiting the installation limiting block 240.
The working principle of the vacuum pipeline sealing connection structure is as follows: when the sealing device is used, the sealing washer 210 on one side of the flange plate 120 has a good sealing effect, the sealing washer 210 has supporting force towards the outer side of the port through the spring 221 in the elastic supporting piece 220 and the telescopic adjusting piece, and the end of the pipeline is not easy to leak when the sealing washer 210 is used for a long time. By rotating the sleeve 223 in the telescopic adjusting part, the sleeve 223 moves transversely while rotating outside the screw 224, so that the distance between the spring 221 and the sealing washer 210 is adjusted, and the sealing washer 210 has stronger reverse supporting force during installation. The annular groove 212 on the outside of the sealing gasket 210 enables the sealing gasket 210 to have this better sealing effect with the port contact surface of the chamber.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
