Description

Technical Field

[0001] This utility model relates to the field of centrifugal compressor unit technology, and in particular to an anti-surge protector for centrifugal compressor units. Background Technology

[0002] A centrifugal compressor unit is a combination of equipment that converts mechanical energy into gas pressure energy. It mainly consists of a centrifugal compressor, a drive motor, a lubrication device, a cooling device, and a control device. The centrifugal compressor is its core component. It uses a high-speed rotating impeller to do work on the gas, accelerating the gas under the action of centrifugal force. Then, it decelerates in the diffuser, converting kinetic energy into pressure energy, thereby increasing the gas pressure. With the continuous advancement of technology, anti-surge protectors specifically designed for centrifugal compressor units are widely used.

[0003] A surge protector for centrifugal compressors is a device specifically designed to prevent surge phenomena in centrifugal compressors. Surge is an unstable operating condition that occurs during the operation of a centrifugal compressor, which can lead to a decrease in compressor performance and even damage to the device. Surge protectors use various mechanisms to prevent and deal with this situation. However, during their operation, due to the complexity of their structure and the presence of moving parts, the sealing difficulty increases, the probability of leakage increases, and the probability of affecting the compressor's performance and the anti-surge effect also increases. In the existing technology, the sealing effect is enhanced by selecting sealing materials according to the compressor's working environment, such as temperature, pressure, and medium. However, after changing the working environment, the same sealing material cannot adapt to different working environments, such as high temperature, cold, and environments containing corrosive media, thereby reducing the sealing effect and reducing the scope of application. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-surge protector for centrifugal compressor units, aiming to improve the problem in the prior art that the same sealing material cannot adapt to multiple working environments after changing the working environment, thereby reducing the sealing effect and the scope of application.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-surge protector for centrifugal compressor units, comprising a valve body, with pipes connected to both the left and right ends of the valve body, and second fixed bend plates installed on the top left and right ends of the valve body. A first fixed bend plate is installed on the top of the pipes. The top left and right ends of the first fixed bend plate and the top left and right ends of the second fixed bend plate are threaded with second screws. A rotating short column is rotatably connected to the top left side of the second fixed bend plate, and a connecting circular plate is fixedly connected to the top right side of the first fixed bend plate. A connecting rope is fixedly connected to the outer side of the rotating short column. A fixed block is fixedly connected to the front left end of the second fixed bend plate, and a second spring is fixedly connected to the left side of the fixed block. Multiple fixed circular plates are equidistantly installed on the outer side of the valve body, and a reminder mechanism is installed at the bottom of the fixed circular plates. The reminder mechanism is used to remind workers of water leakage.

[0006] As a further description of the above technical solution:

[0007] The reminder mechanism includes a box body, which is installed at the bottom of the fixed circular plate. Multiple mounting plates are equidistantly arranged on the outer side of the box body. A fixing plate is fixedly connected inside the box body. A first spring is fixedly connected to the middle of the inner bottom wall of the fixing plate. A rubber plate is installed at the middle of the bottom end of the fixed circular plate. A fixing block is provided at the bottom of the rubber plate. The bottom of the fixing block is fixedly connected to the top of the first spring.

[0008] As a further description of the above technical solution:

[0009] The outer perimeter of the box is fixedly connected with female buckles, and one end of the mounting plate is fixedly connected with a male buckle.

[0010] As a further description of the above technical solution:

[0011] A rotating bent rod is fixedly connected to the middle of the top of the rotating short column, and a protective sleeve is installed on the outside of the rotating bent rod.

[0012] As a further description of the above technical solution:

[0013] The left and right ends of the outer side of the rotating short column are slidably connected with locking rods, and the top of the locking rods is fixedly connected with locking blocks.

[0014] As a further description of the above technical solution:

[0015] Each of the two fixed circular plates has multiple bolts threaded at equal intervals on its adjacent sides, and nuts are threaded onto the outer side of each bolt.

[0016] As a further description of the above technical solution:

[0017] A mounting plate is installed on the front side of the valve body, and multiple first screws are threaded at equal intervals on the outer side of the mounting plate.

[0018] As a further description of the above technical solution:

[0019] A fixed rod is rotatably connected to the middle of the front side of the valve body, and a handle is fixedly connected to the front side of the fixed rod.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when changing the working environment, the sealing material needs to be replaced. First, remove the locking rod, rotate the rotating bend rod to loosen the connecting rope, and then the first and second fixed bend plates spring open under the action of the spring. Unscrew multiple second screws and bolts to separate the pipe from the valve body. After replacing the sealing material, screw and bolts are screwed back on, the bend rod is rotated in the opposite direction to fix the locking rod, and the device installation is completed. This facilitates disassembly and replacement of the sealing material, extends the service life, and expands the scope of application.

[0022] 2. In this utility model, if the fixed circular plate leaks during long-term use, water will accumulate at the bottom, causing the adhesive of the adhesive plate to decrease and making it impossible to fix the connected fixing blocks. The fixing blocks will fall down due to gravity and make a sound when they fall on the fixing plate, alerting the staff to the leak. By installing the first spring, the fixing blocks will continue to make a sound to help locate the leak point. Attached Figure Description

Detailed Implementation

[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 3 and Figure 4This utility model provides an embodiment of an anti-surge protector for a centrifugal compressor unit, comprising a valve body 1, with pipes 9 connected to both the left and right ends of the valve body 1. Second fixed bend plates 12 are installed on the top left and right ends of the valve body 1, and a first fixed bend plate 4 is installed on the top of the pipes 9. Second screws 15 are threadedly connected to the top left and right ends of the first fixed bend plate 4 and the second fixed bend plate 12, respectively, to ensure a more stable installation. A rotating short column 24 is rotatably connected to the top left side of the second fixed bend plate 12, and a connecting circular plate 11 is fixedly connected to the top right side of the first fixed bend plate 4. A connecting rope 17 is fixedly connected to the outer side of the rotating short column 24, allowing adjustment of the distance between the first fixed bend plate 4 and the second fixed bend plate 12. A fixing block 14 is fixedly connected to the front left end of the second fixed bend plate 12, and a fixing block 14 is fixedly connected to the left side of the fixing block 14. A second spring 13 is attached to facilitate the disassembly of the device. Multiple fixed circular plates 10 are equidistantly installed on the outer side of the valve body 1. A reminder mechanism 2 is installed at the bottom of the fixed circular plates 10 to remind the staff of water leakage. A rotating bent rod 18 is fixedly connected to the top center of the rotating short column 24. A protective sleeve 19 is installed on the outer side of the rotating bent rod 18 to prevent the rotating bent rod 18 from slipping out of the hand. A locking rod 21 is slidably connected to the left and right ends of the outer side of the rotating short column 24. A locking block 20 is fixedly connected to the top of the locking rod 21 to prevent unnecessary rotation of the rotating short column 24. Multiple bolts 3 are threadedly connected at equal intervals on the adjacent sides of the two fixed circular plates 10. Nuts 16 are threadedly connected to the outer side of the bolts 3. The installation of bolts 3 and nuts 16 makes the fixed circular plates 10 more securely installed.

[0032] Reference Figure 1 , Figure 2 and Figure 5 The reminder mechanism 2 includes a box body 201, which is installed at the bottom of the fixed circular plate 10. Multiple mounting plates 203 are equidistantly arranged on the outer side of the box body 201. A fixed plate 204 is fixedly connected inside the box body 201. A first spring 205 is fixedly connected to the middle of the inner bottom wall of the fixed plate 204. The installation of the first spring 205 enables the device to emit sound continuously. A rubber plate 206 is installed at the middle of the bottom end of the fixed circular plate 10. A fixing block 202 is provided at the bottom of the rubber plate 206. When the rubber plate 206 is in contact with water for a long time, its adhesiveness will decrease, causing the fixing block 202 to fall. The bottom of the fixing block 202 is fixedly connected to the top of the first spring 205. Female buckles 23 are fixedly connected to all four sides of the outer side of the box body 201. A male buckle 22 is fixedly connected to one end of the mounting plate 203. The engagement of the male buckle 22 and the female buckle 23 facilitates the disassembly of the device.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A mounting circular plate 5 is installed on the front side of the valve body 1. Multiple first screws 8 are threaded at equal intervals on the outer side of the mounting circular plate 5. The installation of the first screws 8 makes the mounting circular plate 5 more stable. A fixing rod 7 is rotatably connected to the middle of the front side of the valve body 1. A handle 6 is fixedly connected to the front side of the fixing rod 7. The installation of the handle 6 makes it easier to use the device.

[0034] Working principle: When the working environment needs to be changed, the sealing material needs to be replaced. At this time, the locking rod 21 is removed by the locking block 20. Then, the rotating bent rod 18 protected by the protective sleeve 19 is rotated, so that the rotating short column 24 starts to rotate, thereby loosening the connecting rope 17. At this time, the first fixed bent plate 4 and the second fixed bent plate 12 will quickly spring apart due to the rebound of the second spring 13. Then, the multiple second screws 15 and bolts 3 are unscrewed to separate the pipe 9 from the valve body 1. At this time, the sealing material can be replaced. After the replacement is completed, the multiple second screws 15 and bolts 3 are screwed on, and the rotating bent rod 18 is rotated in the opposite direction. At the same time, the locking rod 21 is re-fixed to complete the installation of this device. Through the above process, this device can be easily disassembled and the sealing material replaced when the working environment is changed, thereby extending its service life and expanding its application range.

[0035] During long-term use of this device, if water leaks at the fixed circular plate 10, the water will accumulate at the bottom of the fixed circular plate 10 due to gravity. As the adhesive plate 206 is in contact with water for a long time, its adhesiveness will decrease. At this time, the fixing block 202 connected to its bottom will not stick due to the reduced adhesiveness. The fixing block 202 will move downward under the action of gravity and fall to the top of the fixing plate 204. At this time, an sound will be emitted to remind the staff. Through the installation of the first spring 205, the fixing block 202 will emit a sound continuously, thereby reminding the staff of the location of the leak.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
