Abstract
Description
Technical Field
[0001] This utility model relates to the field of compensator technology, and in particular to a sealed spherical compensator. Background Technology
[0002] A spherical compensator is a compensating device used in pipeline systems. It uses a sphere as the main moving part and utilizes the angular displacement of the sphere to absorb the deformation of the pipeline caused by thermal expansion and contraction and mechanical displacement. It can effectively compensate for the axial, lateral and angular displacement of the pipeline, reduce the stress caused by the deformation of the pipeline, and has the characteristics of large compensation capacity, small space occupation, convenient installation and adaptability to complex pipeline layout. It is widely used in pipeline systems in the fields of thermal power, chemical industry and metallurgy.
[0003] Sealed spherical compensators are a special type of spherical compensator. They feature a significantly enhanced sealing structure compared to ordinary spherical compensators. Through the use of high-performance sealing materials and unique sealing designs, such as sealing rings and gaskets, they effectively prevent internal media leakage. They absorb axial, lateral, and angular displacements caused by thermal expansion and contraction and mechanical displacement in pipelines, reducing pipeline deformation stress while ensuring the system's sealing performance and safety. They are commonly used in pipeline systems in the thermal, chemical, and petroleum industries where high sealing performance is required. However, in practice, sealed spherical compensators are primarily used to compensate for lateral displacement in pipelines; their ability to compensate for axial displacement is relatively weak. If a pipeline system experiences both large axial and lateral displacements, it needs to be used in conjunction with other types of compensators. This increases the complexity and cost of the pipeline system. In existing technologies, improvements to the internal structure of sealed spherical compensators, such as increasing the flexibility of the connection between the sphere and the pipeline and adopting a telescopic connection structure, allow the sphere to compensate for lateral displacement while also adapting to axial displacement to a certain extent. However, when the pipeline is displaced, the sphere and the seal will be subjected to significant impact and friction forces. Under such conditions for a long time, the surface of the sphere and the seal will wear rapidly, leading to a decrease in sealing performance and the problem of media leakage. Utility Model Content

[0030] 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.
[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a sealed spherical compensator, comprising a housing 1. Mounting rings 14 are installed at both the upper and lower ends of the outer side of the housing 1. A mounting base plate 10 is fixedly connected to the bottom of the housing 1. Multiple mounting circular plates 6 are fixedly connected at equal intervals to the lower outer side of the housing 1. A fixed thick rod 17 is fixedly connected to the top of the mounting circular plate 6. A telescopic thin rod 8 is slidably connected inside the fixed thick rod 17. A fixed top plate 16 is fixedly connected to the bottom of the mounting rings 14. A spring 11 is fixedly connected to the bottom of the fixed top plate 16. The installation of the spring 11 reduces damage from impacts and tipping. The top of the telescopic thin rod 8 is connected to the bottom of the fixed top plate 16. The bottom of the telescopic rod 8 passes through the middle of the mounting circular plate 6 and is fixedly connected to the fixed circular plate 7. The middle of the fixed circular plate 7 is fixedly connected to the outer side of the mounting base plate 10. A cleaning mechanism 2 is installed on the top right side of the housing 1. The cleaning mechanism 2 is used for cleaning the inside of the housing 1. A rotating cylinder 3 is rotatably connected to the middle of the top right side of the housing 1. A fixed base 15 is fixedly connected to the bottom of the mounting base plate 10. The installation of the fixed base 15 makes the device more stable. Multiple nuts 4 are threaded at equal intervals on the outer side of the mounting ring 14. Bolts 5 are threaded on the bottom outer side of the nuts 4. The installation of the bolts 5 makes the mounting ring 14 securely installed.
[0032] Specifically, during equipment operation, if vibration or displacement occurs, the mounting ring 14 will cause the fixed top plate 16 to bear force, causing the spring 11 to compress or stretch. The spring 11 absorbs energy through its deformation. At the same time, the telescopic thin rod 8 slides synchronously within the fixed thick rod 17, limiting the deviation of the spring 11 during deformation and improving the stability of the buffer direction. The telescopic thin rod 8 can also assist the spring 11 in dispersing stress and further consume kinetic energy through sliding friction. Through the above process, external impact is converted into energy loss due to the deformation of the spring 11 and the sliding of the rod, thereby reducing structural damage to the equipment caused by vibration or displacement and achieving buffer protection for the equipment.
[0033] Reference Figure 1 , Figure 3 and Figure 5 The cleaning mechanism 2 includes a mounting plate 209, which is rotatably connected to the top right end of the housing 1. A cleaning tank 208 is fixedly connected to the rear side of the mounting plate 209. A motor 201 is installed in the middle of the rear side of the cleaning tank 208. The installation of the motor 201 provides power to the subsequent processes. A rotating rod 203 is fixedly connected to the output end of the motor 201. A stirring blade 205 is fixedly connected at equal intervals to the outer side of the rotating rod 203. Multiple nozzles 204 are installed at equal intervals on the front side of the mounting plate 209. A slot block 206 is fixedly connected to the front side of the rotating rod 203. An elastic scraper 207 is engaged in the middle of the front side of the slot block 206. A feed pipe 202 is connected to the top of the rear side of the cleaning tank 208. A circular cover 18 is installed on the rear side of the feed pipe 202. A fixed cylinder 19 is fixedly connected to the middle of the rear side of the circular cover 18. The installation of the circular cover 18 prevents dirt from entering from here.
[0034] Specifically, after starting the motor 201, the rotating rod 203 is driven to rotate, which in turn drives the stirring blade 205 to stir, so that the cleaning liquid injected into the cleaning tank 208 from the feed pipe 202 can be fully mixed. Through the nozzle 204 installed on the front side of the mounting plate 209, the stirred cleaning liquid can be sprayed into the interior of the housing 1 to effectively clean the inner wall. At the same time, the rotation of the rotating rod 203 will also drive the front end slot block 206 and its engaged elastic scraper 207 to rotate together. The elastic scraper 207 is closely attached to the inner wall of the housing 1 and scrapes away stubborn stains during the rotation. Through the installation of the mounting plate 209, the device can be flipped up when not in use, thereby saving space. Through the above process, the cleaning of the interior of the housing 1 is achieved.
[0035] Reference Figure 1 , Figure 2 and Figure 3 Multiple circular holes 9 are equidistantly provided on the outer side of the mounting base plate 10. A slot plate 13 is fixedly connected to the top front side of the housing 1, and a notice board 12 is installed in the middle of the slot plate 13.
[0036] Specifically, the circular hole 9 facilitates the installation of the base plate 10, the slot plate 13 facilitates the replacement of the notice board 12, and the notice board 12 facilitates the reminder to staff.
[0037] Working principle: When vibration or displacement occurs during the operation of the device, the bottom ring 14 drives the fixed top plate 16 to be stressed, causing the spring 11 to be compressed or stretched. The spring 11 absorbs energy through deformation. At the same time, the telescopic thin rod 8 slides synchronously within the fixed thick rod 17, which can limit the displacement of the spring 11 during deformation, ensure the stability of the buffer direction, and at the same time assist the spring 11 in dispersing stress. The kinetic energy is further consumed through sliding friction. Through the above process, the external impact is converted into energy loss due to the deformation of the spring 11 and the sliding of the rod, thereby reducing the structural damage caused by vibration or displacement of the device and realizing the buffer protection of the device.
[0038] The motor 201 is turned on, which drives the rotating rod 203 to rotate, thereby causing the stirring blade 205 to stir and mix the cleaning liquid injected into the cleaning tank 208 from the feed pipe 202 evenly. Through the installation of the nozzle 204 on the front side of the mounting plate 209, the stirred cleaning liquid can be sprayed into the interior of the housing 1 to rinse the inner wall. At the same time, the rotating rod 203 drives the front end slot block 206 and its engaged elastic scraper 207 to rotate together. The elastic scraper 207 is in close contact with the inner wall of the housing 1 and scrapes away stubborn stains during rotation. Through the installation of the mounting plate 209, the device can be flipped up when not in use to avoid occupying too much space. Through the above process, the interior of the housing 1 is cleaned.
