Description

Technical Field

[0001] This invention relates to the technical field of compensators, specifically an adjustable bellows compensator for pipelines. Background Technology

[0002] Bellows compensators are a type of compensating element. They utilize the effective expansion and contraction deformation of their main working body, the bellows, to absorb dimensional changes in pipelines, ducts, and containers caused by thermal expansion and contraction, or to compensate for axial, lateral, and angular displacements. They can also be used for noise reduction and vibration damping. They have wide applications in modern industry. The working principle of bellows compensators is mainly based on the internal bellows structure, which absorbs and disperses the displacement caused by thermal expansion or contraction due to temperature and pressure changes in the pipeline system, thereby reducing the stress on the pipeline system and protecting its safe and stable operation.

[0003] In pipeline systems, the bellows compensator undergoes thermal expansion or contraction due to temperature and pressure changes. Excessive and repeated contraction and stretching of the bellows section may lead to excessive and irreversible deformation, causing damage to the bellows section and affecting the service life of the equipment. Therefore, the inventor designed an adjustable bellows compensator for pipelines to solve the above-mentioned technical problems. Summary of the Invention

[0005] (II) Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: An adjustable corrugated compensator for pipelines, comprising a corrugated pipe body, an inner sleeve and two flange connecting plates, wherein the two ends of the corrugated pipe body are respectively welded to the two flange connecting plates, the inner port of the corrugated pipe body is welded to the outer side of one end of the inner sleeve, and the two flange connecting plates are each provided with corresponding protrusions in an annular arrangement, the corresponding protrusions are connected to each other by an adjustable thread structure, and the annular outer side of the inner sleeve is provided with an annular embedding groove corresponding to the inner corrugation of the corrugated pipe body, and an irregular high-pressure airbag is sandwiched between the annular embedding groove and the inner corrugation of the corrugated pipe body; A reinforcing section is provided in the middle of the corrugated pipe body. A duct is provided in the corresponding part of the irregular high-pressure airbag and the reinforcing section. The duct passes through the reinforcing section and extends to the outside. A pressure gauge and a pressure reducing valve are installed on the duct in sequence.

[0007] Preferably, the irregularly shaped high-pressure airbag is in an inflated state during use, and the inflated high-pressure airbag fits against the corrugated inner wall of the bellows body.

[0008] Preferably, a sealing ring is provided between the outer port of the inner sleeve and the corrugated pipe body.

The sealing ring can effectively prevent fluid in the pipeline system from overflowing into the gap between the corrugated pipe body and the inner sleeve.

[0009] Preferably, the corresponding protrusions between the two flange connecting discs are provided with an adjustable thread structure, which includes a corresponding threaded rod and a lock nut.

[0010] Preferably, the pressure gauge displays the air pressure value inside the irregular high-pressure airbag, and the pressure gauge monitors the air pressure inside the irregular high-pressure airbag in real time, thereby monitoring the stretching and contraction changes of the bellows body through the pressure changes inside the irregular high-pressure airbag.

[0011] Preferably, the reinforcing part is integrally formed with the corrugated pipe body, which effectively enhances the overall structural integrity of the equipment.

[0012] (III) Beneficial Effects: This invention provides an adjustable bellows compensator for pipelines. It possesses the following beneficial effects: (1) The adjustable bellows compensator for pipelines strengthens the bellows body with a soft structure by setting up a special-shaped high-pressure airbag, which changes the non-adjustability of the traditional bellows structure, enhances the applicability of the bellows compensator, and effectively buffers and protects the bellows body, reduces the internal stress caused by equipment deformation, and improves the adjustability of the bellows compensator.

[0013] (2) The adjustable bellows compensator for pipelines has a reinforcing part on the bellows body, which can effectively increase the tensile and shrinkage strength of the bellows body and effectively reduce the stress deformation caused by thermal expansion and contraction of the pipeline system.

[0014] (3) The adjustable corrugated compensator for pipelines has a sealing ring sandwiched between the corrugated pipe body and the inner sleeve, which can effectively prevent the fluid inside the pipeline system from overflowing into the gap between the corrugated pipe body and the inner sleeve.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1-2 As shown, the present invention provides a technical solution: an adjustable bellows compensator for pipelines, comprising a bellows body 1, an inner sleeve 2, and two flange connecting plates 3. Both ends of the bellows body 1 are welded to the two flange connecting plates 3 respectively. The inner port of the bellows body 1 is welded to the outer side of one end of the inner sleeve 2. Each of the two flange connecting plates 3 has corresponding protrusions arranged in a ring. The corresponding protrusions are connected by an adjustable thread structure 4. The corresponding protrusions between the two flange connecting plates 3 are correspondingly arranged with the adjustable thread structure 4. The adjustable thread structure 4 includes a corresponding threaded rod and a lock nut. The inner sleeve... An annular groove 5 is formed on the outer surface of the bellows 2, corresponding to the inner corrugations of the bellows body 1. A shaped high-pressure airbag 11 is sandwiched between the annular groove 5 and the inner corrugations of the bellows body 1. The shaped high-pressure airbag 11 is in an inflated state during use and fits against the inner corrugated wall of the bellows body 1. A sealing ring 6 is sandwiched between the outer port of the inner sleeve 2 and the bellows body 1. The sealing ring 6 is located at the end away from the welding of the inner sleeve 2. The sealing ring 6 can effectively prevent fluid in the pipeline system from overflowing into the gap between the bellows body 1 and the inner sleeve 2. A reinforcing section 7 is provided in the middle of the corrugated pipe body 1. The reinforcing section 7 is integrally formed with the corrugated pipe body 1, effectively enhancing the overall structural integrity of the equipment. A gas guide pipe 8 is provided at the corresponding part of the irregularly shaped high-pressure airbag 11 and the reinforcing section 7. The gas guide pipe 8 passes through the reinforcing section 7 and extends to the outside. A pressure gauge 9 and a pressure reducing valve 10 are sequentially installed on the gas guide pipe 8. The exhaust port of the pressure reducing valve 10 is connected to a pressure stabilizing device. The pressure stabilizing device introduces high-pressure gas into the irregularly shaped high-pressure airbag 11 through the pressure reducing valve 10. The pressure gauge 9 displays the gas pressure value inside the irregularly shaped high-pressure airbag 11. The pressure gauge 9 monitors the gas pressure inside the irregularly shaped high-pressure airbag 11 in real time, and monitors the stretching and contraction changes of the corrugated pipe body 1 by monitoring the pressure changes inside the irregularly shaped high-pressure airbag 11. All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0019] In summary, when the equipment is in use, the corrugated pipe body 1 is connected to the pipeline system through the flange connection plate 3. The pressure is regulated by the external pressure stabilizing system of the pressure reducing valve 10. When the corrugated pipe is in use, the stress of thermal expansion and contraction of the pipeline system stretches or compresses the corrugated pipe body 1, so that the irregular high-pressure air bag 11 can follow the corrugated pipe body 1 to undergo soft deformation, effectively reducing the stress deformation of the corrugated pipe body 1.

[0020] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
