[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figure 1The present invention provides a jacketed flange with a sealed isolation cavity, comprising: an inner flange 2 and a connecting structure 3. An outer flange 1 is mounted on the upper surface of the inner flange 2 by means of the connecting structure 3, and the connecting structure 3 is mounted on the upper surface of the outer flange 1.

[0024] In the embodiments of this utility model, please refer to Figures 2 to 4The connecting structure 3 includes three connecting grooves 304, a rotating ring 301, and three fixing rods 307. All three connecting grooves 304 are formed on the outer flange 1. The rotating ring 301 is rotatably connected to the outer flange 1, and the three fixing rods 307 are fixedly connected to the outer flange 1. A positioning plate 315 is slidably connected to the inner wall of the connecting groove 304. A slot 305 is formed on the inner wall of the positioning plate 315, and a locking plate 306 is slidably connected to the slot 305. The rotating ring 301 is fixedly connected to the locking plate 306. Three limiting grooves 302 and six... The positioning groove 303 and the limiting groove 302 are interconnected with each other. The fixing rod 307 is slidably connected to the limiting groove 302. The arc surface of the limiting groove 302 is slidably connected to the positioning post 308. The positioning post 308 is slidably connected to the positioning groove 303. The arc surface of the three fixing rods 307 is slidably connected to the moving ring 309. The moving ring 309 is fixedly connected to the three positioning posts 308. The arc surface of the fixing rod 307 is fitted with a spring 313. The two ends of the spring 313 are fixedly connected to the fixing rod 307 and the moving ring 309, respectively. When personnel need to assemble and fix the outer flange 1 and inner flange 2, they can move the outer flange 1 to slide the positioning plate 315 into the inner wall of the connecting groove 304. Then, the personnel can rotate the rotating ring 301 until the clamping plate 306 slides into the inner wall of the clamping groove 305. At this time, the spring 313 rebounds, causing the positioning pin 308 to slide into the inner wall of the positioning groove 303. This allows for quick and easy assembly and fixing of the outer flange 1 and inner flange 2, improving installation efficiency. The curved surface of the spring 313 is fitted with a bellows 314, and both ends of the bellows 314 are fixedly connected to the fixing rod 307 and the moving ring 309, respectively. The bellows 314 protects the spring 313 and extends its service life. Three handles 310 with circular cross-sections are fixedly connected to the upper surface of the moving ring 309. The handle 310 facilitates the movement of the movable ring 309, improving ease of operation. An anti-slip sleeve 312, with a hollow circular cross-section, is fixedly connected to the arc surface of the handle 310. The anti-slip sleeve 312 increases friction between the user's hand and the handle 310, preventing slippage during movement. A guide block 311 is fixedly connected to the upper surface of the positioning plate 315. The guide block 311 guides the positioning plate 315, allowing it to slide easily into the inner wall of the connecting groove 304. The movable ring 309 is made of stainless steel. Stainless steel rings have high strength and good wear resistance, preventing deformation of the movable ring 309 during short-term use. The working principle of the jacketed flange with isolation cavity sealing provided by this utility model is as follows: When personnel need to connect and fix the outer flange 1 and the inner flange 2 to form an isolation cavity between them, the isolation cavity is used to increase the sealing performance and prevent leakage of the medium in contact with the flange. Then, when personnel need to connect and fix the outer flange 1 and the inner flange 2, they can first move the outer flange 1, moving it closer to the inner flange 2, so that the guide block 311 and the positioning plate 315 slide into the inner wall of the connecting groove 304. The guide block 311 guides the positioning plate 315, allowing personnel to easily slide the positioning plate 315 into the inner wall of the connecting groove 304 until the cavities between the outer flange 1 and the inner flange 2 abut. Then, with the help of the anti-slip sleeve 312, the personnel move the handle 310 upwards. The anti-slip sleeve 312 increases the friction between the personnel's hand and the handle 310, preventing slippage during movement. The handle 310 then moves the moving ring 309 upwards. The handle 310 facilitates the movement of the personnel's hand. The movable ring 309 moves to improve the ease of operation for personnel. The movable ring 309 drives the bellows 314 and spring 313 to wind up. The movable ring 309 also drives the positioning pin 308 upwards until the positioning pin 308 completely slides out of the inner wall of the positioning groove 303. Then, the operator rotates the rotating ring 301, which drives the clamping plate 306 to move closer to the positioning plate 315. At this time, the fixing rod 307 slides on the inner wall of the limiting groove 302 until the clamping plate 306 slides into the inner wall of the clamping slot 305. The bellows... The tube 314 can protect the spring 313 and extend its service life. At this time, the fixing rod 307 abuts against the side wall of one end of the limiting groove 302. Then, when the anti-slip sleeve 312 is released, the spring 313 rebounds, causing the positioning pin 308 to move towards the positioning groove 303 until the positioning pin 308 slides into the inner wall of the positioning groove 303. The moving ring 309 is a stainless steel ring. The stainless steel ring has high strength and good wear resistance, which can prevent the moving ring 309 from deforming during short-term use.
