Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the quick-replacement double-rupture-disc device comprises a fixed pressure pipeline 1, a sleeve flange 2, a moving pipeline 3, a screw blocking cover 4, a guide thread block 5, a push-pull screw 6, a synchronous transmission chain wheel set 7 (comprising a driving wheel 11, a driven wheel 12 and a tension wheel 13), a spiral lifter 8, a fixed pressure pipeline 9 and a rupture disc 10. Wherein fixed pressure pipeline 1 and fixed pressure pipeline 9 are fixed with ground, provide the atress for quick replacement double rupture disk device and support. The screw plugging cover 4 and the guide thread block 5 are fixedly connected with flanges on the moving pipeline 3 and the fixed pressure pipeline 9 respectively, the push-pull screw 6 and the guide thread block 5 are screwed in and fixed, then the screw plugging cover 4 is used for limiting, force is transmitted to the moving pipeline 3 through the screw plugging cover 4, and the moving pipeline 3 is driven to move along the axial direction. In order to prevent the movable pipeline 3 from generating eccentric force to cause movement jam, the movable pipeline 3 is symmetrically driven, the symmetrical two-side push-pull screw rods 6 need to ensure synchronous movement, the synchronous movement is ensured by a synchronous transmission chain wheel group 7, the structure of the synchronous transmission chain wheel group is arranged as shown in figure 3, and the synchronous transmission chain wheel 7 is integrally arranged on a retainer and synchronously moves along with the movable pipeline 3. The spiral lifter 8 is a power source component and provides movement displacement and output force for the quick replacement of the double rupture disk device. The sealing form between the sleeve flange 2 and the moving pipeline 3 is shown in fig. 4, and consists of a sealing ring 14 and a sealing ring retainer ring 15, so that high-pressure sealing can be ensured, and relative sliding between the sleeve flange 2 and the moving pipeline 3 can be realized.
When the rupture disk is disassembled, firstly, the fastening bolt for clamping the rupture disk flange is loosened. The screw elevator 8 is started to drive the synchronous transmission chain wheel set 7 to rotate, the push-pull screw rods 6 with symmetrical sides are driven to rotate at the same time, the push-pull screw rods 6 rotate in the guide thread blocks 5 and translate leftwards at the same time, and the compaction screw rod plugging cover 4 pushes the moving pipeline 3 to move leftwards. When the moving pipe 3 moves a sufficient distance to the left, the rupture disk 10 on the right has a sufficient space for disassembly. When the left rupture disk 10 is replaced, the spiral lifter 8 is started reversely, the moving pipeline 3 moves rightwards, the sleeve flange 2 and the moving pipeline 3 move together under the action of the friction force of the sealing ring, and after the left rupture disk 10 moves rightwards for a sufficient distance, the left rupture disk 10 has enough disassembly space to be disassembled.
