Description

Technical Field

[0001] The utility model relates to a bellows compensator, in particular to an adjustable bellows compensator, belonging to the technical field of compensators. Background Art

[0002] Compensators are also commonly called expansion joints, or telescopic joints. They are composed of bellows and end pipes, brackets, flanges, ducts and other accessories that constitute their working body. They are a kind of compensation element that can be used to reduce noise and vibration. They are widely used in modern industry and are usually used in heating. In order to prevent the heating pipeline from deforming or damaging due to thermal elongation or temperature stress when the heating pipeline is heated, a compensator needs to be installed on the pipeline. In order to face pipelines on different axes, an adjustable bellows compensator is generally used.

[0003] An adjustable bellows compensator disclosed in the Chinese patent application disclosure specification CN219623501U fixes the sliding plate and the sliding sleeve together by a first fastening bolt, pulls the sliding sleeve to rotate on the support plate, so that the other flange plate moves horizontally with the fixed flange plate, realizes the fixed connection of two coaxial and parallel pipe joints, and improves the practicality of the bellows.

[0004] However, in the technical solution of the above-mentioned comparative document, the bellows compensator lacks a corresponding leakage alarm mechanism. Since the temperature difference between the inside and outside of the bellows compensator is large, the elongation of the compensator is large, and the bellows will repeatedly expand and contract during operation, which will greatly affect the service life of the bellows. When the bellows leaks, the staff cannot be informed in time, which may lead to major production accidents. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The purpose of the utility model is to provide an adjustable bellows compensator in order to solve the above problems, so as to solve the problem that the prior art does not have a leakage alarm function, resulting in the staff being unable to promptly know when the bellows compensator is damaged.

[0007] (II) Technical solution

[0008] The utility model is implemented through the following technical scheme: an adjustable bellows compensator, comprising two flanges, wherein an alarm mechanism is arranged on the outer side of one of the flanges, the alarm mechanism comprises two hoses, and the ends of the two hoses close to each other are commonly fixedly connected to a fixing tube, the outer surface of the fixing tube is fixedly connected to a fixing box, a rectangular opening is opened on the bottom surface of the fixing box, a cross plate is fixedly connected to the inner wall of the fixing box, a fan is fixedly connected to the upper surface of the cross plate, a controller and a battery are respectively fixedly connected to the inner bottom wall of the fixing box, a water immersion sensor and a temperature sensor are respectively fixedly connected to the bottom surface of the fixing box, and the controller is electrically connected to the fan, the water immersion sensor and the temperature sensor respectively through wires.

[0009] Preferably, the sides of the two flanges close to each other are fixedly connected with a bellows, and the inner wall of the bellows is fixedly connected with a flow guide pipe. The bellows and the flow guide pipe are both existing technologies and this application does not make further limitations.

[0010] Preferably, two groups of circular holes are opened on the left side of each flange, and the ends of the two hoses that are away from each other are fixedly connected to the side surfaces of the two flanges that are close to each other. The circular holes are for facilitating the installation of bolts to ensure that the connection time can be reduced when connecting to the pipeline.

[0011] Preferably, the outer surface of each flange is fixedly connected to a fixing block, and each fixing block is fixedly connected to two rectangular plates on a side close to the fixing tube. By providing the fixing block and the rectangular plate, the fixing block can be used to provide support and fixation for the rectangular plate.

[0012] Preferably, the inner wall of each rectangular plate is fixedly connected to a bearing, and the inner ring of each group of bearings is commonly fixedly connected to a rotating shaft. The rotating shaft can be fixed by the bearing to fill the gap between the rotating shaft and the rectangular plate without affecting the operating status of the two.

[0013] Preferably, two groups of the rotating shafts have two rectangular frames fixedly connected to their outer surfaces, and another two rotating shafts have two sliding plates fixedly connected to their outer surfaces, and the outer surface of each sliding plate is slidably connected to the inside of the rectangular frame. Through the rectangular frame and the sliding plate, the sliding plate can be used to slide inside the rectangular frame, thereby extending according to the extension of the compensator.

[0014] Preferably, two partitions are fixedly connected to the inner wall of the fixed box, and the side surfaces of the two partitions close to each other are fixedly connected to the two side surfaces of the cross plate respectively. The interior of the fixed box can be divided into three spaces through the partitions, so that the three electronic components inside the fixed box do not affect each other during operation.

[0015] The utility model provides an adjustable bellows compensator, which has the following beneficial effects:

[0016] 1. This adjustable bellows compensator uses the mutual cooperation between the hose and the fixed tube, and connects the hose with the flange to ensure that the hose can extend along with the extension of the compensator. The fixed box can be fixed by the fixed tube, which can provide a fixed position for subsequent alarms and detection devices, and does not affect the normal extension of the compensator.

[0017] 2. The rectangular mouth, cross plate and fan of this adjustable bellows compensator cooperate with each other, and the cross plate is used to provide better support for the fan. The fan can extract the hot air inside the fixed box to prevent condensation of water droplets inside the fixed box due to the large temperature difference between the inside and outside of the compensator. In combination with the water immersion sensor and the temperature sensor, the temperature inside the fixed box can be detected, providing the prerequisite for the operation of the fan. The water immersion sensor can effectively detect whether the compensator is damaged and cause internal hot water leakage, thereby ensuring that in the early stage of compensator damage, the staff can promptly obtain leakage information and reduce losses.

[0030] See also Figure 1 and Figure 2 The alarm mechanism 5 includes two hoses 503, and the ends of the two hoses 503 that are close to each other are fixedly connected to a fixing tube 504. Two groups of circular holes 4 are opened on the left side of each flange 1. The ends of the two hoses 503 that are far away from each other are respectively fixedly connected to the side surfaces of the two flanges 1 that are close to each other. By providing the circular holes 4, the flange 1 can be installed on the pipeline through the circular holes 4 and bolts, which is convenient for connection.

[0031] See also Figure 1 , Figure 2 and Figure 4 The outer surface of the fixed cylinder 504 is fixedly connected to the fixed box 502, and a rectangular opening 501 is opened on the bottom surface of the fixed box 502. The outer surface of each flange 1 is fixedly connected to a fixed block 6, and each fixed block 6 is fixedly connected to two rectangular plates 10 on a side close to the fixed cylinder 504. By providing the fixed block 6 and the rectangular plate 10, the rectangular plate 10 can be fixed by the fixed block 6, thereby providing a better supporting force for the rectangular plate 10.

[0032] See also Figure 3 and Figure 4 The inner wall of the fixed box 502 is fixedly connected with a cross plate 507, the upper surface of the cross plate 507 is fixedly connected with a fan 508, the inner wall of each rectangular plate 10 is fixedly connected with a bearing 9, and the inner ring of each group of bearings 9 is fixedly connected with a rotating shaft 8. By providing the bearings 9 and the rotating shaft 8, the rotating shaft 8 can be fixed by the bearings 9 to ensure that the rotating shaft 8 runs more stably.

[0033] See also Figure 3 and Figure 4 The inner bottom wall of the fixed box 502 is respectively fixedly connected with a controller 505 and a battery 509, and the bottom surface of the fixed box 502 is respectively fixedly connected with a water immersion sensor 506 and a temperature sensor 510, wherein the outer surfaces of the two groups of rotating shafts 8 are fixedly connected with two rectangular frames 12, and the outer surfaces of the other two rotating shafts 8 are fixedly connected with two sliding plates 7, and the outer surface of each sliding plate 7 is slidably connected to the inside of the rectangular frame 12. By providing the rectangular frame 12 and the sliding plate 7, the sliding plate 7 can slide inside the rectangular frame 12 and can extend along with the extension of the compensator.

[0034] See also Figure 3 and Figure 4 The controller 505 is electrically connected to the fan 508, the water immersion sensor 506 and the temperature sensor 510 through wires. Two partitions 11 are fixedly connected to the inner wall of the fixed box 502. The sides of the two partitions 11 close to each other are fixedly connected to the two sides of the cross plate 507 respectively. By providing the partitions 11, the interior of the fixed box 502 can be divided into three spaces by the partitions 11 to ensure that the devices do not affect each other.

[0035] When the utility model is in use: first, respectively connect the water immersion sensor 506, the fan 508, the temperature sensor 510 and the controller 505 to the power supply. When the power supply is connected, the device can be used normally. When the device needs to be installed, it is only necessary to contact the two flanges 1 with the two pipe openings respectively, and then connect and stabilize them through bolts and circular holes 4. When hot water passes through the inside of the guide tube 2, the guide tube 2 will transfer the heat to the bellows 3, and then the internal temperature of the fixed tube 504 will also increase. However, at this time, the temperature outside the fixed tube 504 is low, so water droplets will condense on the inner wall of the fixed tube 504, and the temperature sensor 510 fixed on the bottom surface of the fixed box 502 will receive a signal of temperature rise, and then the temperature sensor 510 will transmit information to the controller 505 through an electrical signal. The controller 505 again controls the operation of the fan 508 through an electrical signal, and the heat inside the fixed tube 504 is blown out by the fan 508 to prevent internal condensation of water droplets. The fixed cylinder 504 can guide the outside air to the inside of the fixed cylinder 504 through the ventilation holes opened on the surface. When the bellows 3 is broken, the hot water inside will accumulate in the fixed cylinder 504 through the damaged part. When the water immersion sensor 506 detects the accumulated water source, the water immersion sensor 506 also transmits information to the controller 505 through an electrical signal, and the controller 505 will transmit the information to the monitoring room, thereby achieving the purpose of the alarm. The water immersion sensor 506 uses the refraction and reflection principle of light in different medium cross-sections for detection. LEDs and photoelectric receivers are placed in the device. When the detector is placed in the air, due to total reflection, most of the LED photons are received by the photoelectric receiver. When it is close to the surface of the hemisphere, due to the refraction of light, the LED photons received by the photoelectric receiver will be reduced, so that the output will also change and an alarm will be generated, effectively avoiding the problem that the device does not have a leakage alarm function when it is in use, which may cause a major production accident.
