Description

Technical Field

[0001] This utility model relates to the field of turbine expander technology, specifically a sealing structure for a turbine expander. Background Technology

[0002] A turbo expander utilizes pressurized gas to perform adiabatic expansion and do work by consuming the gas's internal energy, thereby intensely cooling the gas to achieve refrigeration. When high-pressure gas or steam passes through the rotor blades of the turbo expander, it drives the rotor to rotate, converting the fluid's pressure energy into mechanical energy, which can be used for refrigeration or energy recovery.

[0003] Since turbine expanders need to be connected to pipelines, most existing connection methods use flange structures, which require a large number of bolts. The vibration of the turbine expander during operation may cause the rubber sealing ring to shift, resulting in wear or even breakage, affecting the sealing effect and causing the connection to be not tight enough. Existing maintenance is inconvenient, requiring tools and a lot of time for disassembly and assembly. Therefore, a sealing structure for turbine expanders is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a new technical solution: a sealing structure for a turbine expander, including a turbine expander 1, and a first connecting plate 2 fixedly installed on the outer surface of the turbine expander 1;

[0029] The turbine expander 1 is equipped with a sealing mechanism, which includes a second connecting plate 3, a connecting pipe 4, a first rubber sealing ring 5, a connecting pipe 6, a second rubber sealing ring 7, a hollow column 8, a round hole 9, a ball 10, a spring 11, a ring 12, a sliding roller 13, a pull ring 14, a groove 15, a slot 16, a locking hole 17, a first sealing groove 18, and a second sealing groove 19.

[0030] Furthermore, multiple slots 16 are formed in the inner wall of the first connecting plate 2, and multiple locking holes 17 are respectively formed in the inner wall of the multiple slots 16;

[0031] The first sealing groove 18 is formed in the inner wall of the connecting pipe of the turbine expander 1, and the second sealing groove 19 is formed on the right surface of the connecting pipe of the turbine expander 1.

[0032] Furthermore, the connecting pipe 4 is disposed on the right surface of the turbine expander 1, and the second connecting plate 3 is fixedly sleeved on the outer surface of the connecting pipe 4;

[0033] The first rubber sealing ring 5 is fixedly installed on the left surface of the connecting pipe 4.

[0034] Furthermore, the connecting pipe 6 is fixedly installed in the inner wall of the connecting pipe 4, and the second rubber sealing ring 7 is fixedly sleeved on the outer surface of the connecting pipe 6.

[0035] Furthermore, multiple hollow columns 8 are inserted into the inner wall of the second connecting plate 3, multiple round holes 9 are respectively opened on the outer surface of multiple hollow columns 8, and multiple round beads 10 are respectively disposed in the inner wall of multiple round holes 9.

[0036] Furthermore, multiple springs 11 are fixedly installed in the inner walls of multiple hollow columns 8, and multiple rings 12 are fixedly installed at the left ends of multiple springs 11.

[0037] Furthermore, multiple sliding rollers 13 are respectively fixedly sleeved in the inner wall of multiple rings 12, multiple grooves 15 are respectively opened on the outer surface of multiple sliding rollers 13, and multiple pull rings 14 are respectively fixedly installed on the right end of multiple sliding rollers 13.

[0038] When the sealing structure of this turbine expander is in use, pulling the pull ring 14 causes the sliding roller 13, which is fixedly mounted on the left surface, to slide to the right on the inner surface of the hollow column 8. The sliding roller 13 causes the ring 12, which is fixedly sleeved on the outer surface, to move to the right. The ring 12 applies a certain pressure to the spring 11, which is fixedly mounted on the right surface, causing it to contract. At this time, the groove 15 on the outer surface of the sliding roller 13 aligns with the circular hole 9 on the outer surface of the hollow column 8. The groove 15 on the outer surface of the sliding roller 13 no longer applies pressure to the beads 10 on the hollow column 8. The beads 10 on the hollow column 8 retract into the hollow column 8. Then, by inserting the hollow column 8, which is fixedly sleeved in the second connecting plate 3, into the slot 16 on the right surface of the first connecting plate 2, and aligning the circular hole 9 on the outer surface of the hollow column 8 with the locking hole 17 on the inner wall of the slot 16, the pull ring 14 is no longer pulled, and the spring 11 does not... When subjected to force, the spring 11 expands, and the spring 11 applies a leftward thrust to the ring 12 fixedly installed on the left surface. The ring 12 drives the sliding roller 13 fixedly sleeved on the inner surface to move to the left. At this time, the sliding roller 13 hits the cylinder set in the circular hole 9 and makes it protrude from the hollow column 8 and engage with the locking hole 17 opened in the inner wall of the slot 16 for fixation. At this time, the installation of the second connecting plate 3 and the first connecting plate 2 is completed. At the same time, the connecting pipe 4 fixedly installed on the inner surface of the second connecting plate 3 is inserted into the first sealing groove 18 opened on the right surface of the first connecting plate 2, and the joint is sealed by the first rubber sealing ring 5 fixedly installed on the left surface of the connecting pipe 4. At the same time, the connecting pipe 6 fixedly installed on the inner surface of the connecting pipe 4 fills into the inner wall of the turbine expander 1, and the second rubber sealing ring 7 fixedly installed on the outer surface of the connecting pipe 6 fills into the first sealing groove 18 opened in the inner wall of the connecting pipe 4 for sealing.

[0039] The turbine expander uses a sealing structure. During the installation of the connecting plate, the connecting pipe 4 is inserted into the second sealing groove 19 of the first connecting plate 2, and the connection seam is sealed by the first rubber sealing ring 5. At the same time, the second rubber sealing ring 7 on the outer surface of the connecting pipe 6 fills the first sealing groove 18 on the inner wall of the connecting pipe. This double sealing design effectively prevents media leakage, improves sealing performance, helps maintain a stable working environment inside the turbine expander, reduces energy loss, and improves the efficiency and reliability of the equipment. The sealing structure of the turbine expander controls the movement of components such as the sliding roller 13, the ring 12, and the spring 11 by pulling the pull ring 14, causing the ball 10 on the hollow column 8 to contract or protrude, thereby achieving the snap-fit ​​fixation between the hollow column 8 and the slot 16. This connection method ensures a tight connection between the second connecting plate 3 and the first connecting plate 2, preventing loosening and ensuring the stability of the equipment structure. It eliminates the need for complex tools and cumbersome operating procedures, which helps improve the installation and maintenance efficiency of the equipment and reduces labor and time costs.
