Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figure 1 and Figure 5 shown, a kind of flange for chemical pipelines provided in this embodiment includes a first pipeline 100 and a second pipeline 200. One end of the first pipeline 100 is fixedly provided with a sleeve seat 110, and one end of the second pipeline 200 is fixedly provided with an insertion seat 210. The insertion seat 210 is inserted into the inside of the sleeve seat 110. A connection structure is arranged between the sleeve seat 110 and the insertion seat 210. Insert strips 111 are arranged on both sides of the inner wall of the sleeve seat 110, and notch grooves 211 matching with the insert strips 111 are opened on both sides of the insertion seat 210. The connection structure includes an annular groove 250. The annular groove 250 is opened inside the insertion seat 210. Perforations are opened on both sides of the annular groove 250. Rotating sleeves 251 connected to the perforations are rotatably installed on both sides inside the annular groove 250. A connection groove 254 is opened inside the sleeve seat 110. A connection hole connected to the perforation is opened on one side of the connection groove 254. A mounting screw 253 penetrates through the inside of the connection hole. One end of the mounting screw 253 is inserted into the connection groove 254, and the other end of the mounting screw 253 penetrates through the perforation and is inserted into the inside of the rotating sleeve 251. Limiting blocks are arranged on both sides of the inner wall of the perforation, and limiting grooves are opened on both sides of the mounting screw 253. One end of the limiting block is movably inserted into the inside of the limiting groove. A special-shaped gear 252 is fixedly sleeved on the outer side of the rotating sleeve 251. A rotating gear disk 255 is rotatably installed inside the annular groove 250. The rotating gear disk 255 meshes with the special-shaped gear 252. A slide groove 220 is opened on one side of the annular groove 250. A slide block 230 penetrates through the inside of the slide groove 220. One end of the slide block 230 is connected to the rotating gear disk 255. A limiting structure is arranged at one end of the slide block 230;

[0029] In this embodiment, the insertion seat 210 is inserted into the interior of the sleeve seat 110, and the insertion bar 111 is inserted into the interior of the notch groove 211, so that the connection hole is connected to the perforation. The user pushes the slider 230, and the slider 230 moves along the chute 220. The movement of the slider 230 drives the rotation gear disc 255 to rotate inside the annular groove 250. The rotation gear disc 255 drives a plurality of rotating sleeves 251 to rotate through the special-shaped gear 252. The cooperation between the limiting block and the limiting groove enables the mounting screw 253 to move outward from the insertion seat 210 as the rotating sleeve 251 rotates. One end of the mounting screw 253 passes through the connection hole and is inserted into the interior of the connection groove 254, so that the insertion seat 210 can be quickly connected to the sleeve seat 110, and the connection structure is arranged inside to prevent it from being exposed for a long time and not being affected by the environment.

[0030] As Figures 1 to 4 shown, a flange for a chemical pipeline provided in this embodiment, the limiting structure includes a movable clamping ring 240. The movable clamping ring 240 is rotatably installed on the surface of the insertion seat 210 and is located on one side of the chute 220. The movable clamping ring 240 is in contact with the slider 230. One end of the movable clamping ring 240 is provided with a slot 241, and one side of the movable clamping ring 240 is provided with a clamping groove 242. The clamping groove 242 is connected to the slot 241. One side of the insertion seat 210 is rotatably installed with a movable clamping rod 243. One end of the movable clamping rod 243 passes through the slot 241, and a threaded clamping sleeve 244 is rotatably installed on the surface of the movable clamping rod 243. The threaded clamping sleeve 244 is threadedly connected to the movable clamping rod, and one end of the movable clamping rod is inserted into the interior of the clamping groove 242;

[0031] In this embodiment, after the insertion seat 210 is connected to the sleeve seat 110, the slider 230 moves to one end of the chute 220. The user rotates the movable clamping ring 240 so that the movable clamping ring 240 is in contact with one side of the slider 230. The user rotates the movable clamping rod 243, and the movable clamping rod 243 is inserted into the interior of the slot 241. The user rotates the threaded clamping sleeve 244, and one end of the threaded clamping sleeve 244 is inserted into the interior of the clamping groove 242, so that the movable clamping ring 240 cannot rotate, thereby preventing the slider 230 from moving inside the chute 220, and indirectly strengthening the connection between the mounting screw 253 and the connection hole.

[0032] As Figure 3 and Figure 4As shown in the figure, a flange for a chemical pipeline provided in this embodiment has a sealing structure on the side where the sleeve seat 110 is in contact with the insertion seat 210. The sealing structure includes a sealing groove 264, which is opened on one side inside the sleeve seat 110. An active sealing ring 260 is inserted into the sealing groove 264. A fixed sealing ring 261 is movably inserted into the active sealing ring 260. One end of the fixed sealing ring 261 is connected to one end of the insertion seat 210. A pressure ring 265 is movably installed inside the fixed sealing ring 261. A pressure rod 262 is installed on one side of the pressure ring 265. One end of the pressure rod 262 is connected to the active sealing ring 260. A compression spring 263 connected to the pressure ring 265 is sleeved on the surface of the pressure rod 262;

[0033] In this embodiment, when the insertion seat 210 is inserted into the sleeve seat 110, the active sealing ring 260 is inserted into the sealing groove 264. As the insertion seat 210 is connected to the sleeve seat 110, the fixed sealing ring 261 moves into the active sealing ring 260. The active sealing ring 260 drives the pressure ring 265 to move through the pressure rod 262, stretching the compression spring 263. Under the reaction force of the compression spring 263, the connection between the active sealing ring 260 and the sealing groove 264 is strengthened, and the sealing performance between the insertion seat 210 and the sleeve seat 110 is enhanced.
