Description

Technical Field

[0001] This utility model relates to the field of hydrogen-oxygen separation technology, and in particular to a detachable hydrogen-oxygen separator outlet connector structure. Background Technology

[0002] In the field of hydrogen-oxygen separation technology, hydrogen-oxygen separators, as core equipment for achieving efficient separation of hydrogen and oxygen after water decomposition, are widely used in many important industrial sectors such as new energy, chemical industry, and medical industry. The outlet connector, as a key component connecting the separator body to the external gas pipeline, directly affects the safety, sealing performance, and ease of maintenance of the entire hydrogen-oxygen delivery system.

[0003] After the hydrogen-oxygen separator completes its separation operation, a certain pressure of hydrogen or oxygen will remain inside and in the outlet connector channel. Since traditional outlet connectors do not have any special structure to release the pressure at the connector in advance, during the process of the operator disassembling the connector, as the seal between the connector and the separator body or gas pipeline is gradually released, the high-pressure gas remaining at the connector cannot be discharged in an orderly and controllable manner. At this time, the high-pressure gas is very likely to form a strong gas jet phenomenon at the moment the seal is broken. This gas jet will not only cause the disorderly diffusion of gases with specific properties such as hydrogen and oxygen, but if the hydrogen concentration reaches the explosion limit and encounters a source of ignition, it will cause a serious safety accident. At the same time, the high-speed jet of gas may also cause physical injury to the operator, such as physical discomfort caused by airflow impact or the risk of parts splashing. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art by providing a detachable hydrogen-oxygen separator outlet connector structure. This structure addresses the issue that after the hydrogen-oxygen separator completes its separation operation, a certain pressure of hydrogen or oxygen remains inside and in the outlet connector channel. Because traditional outlet connectors lack any dedicated structure for pre-releasing pressure at the connector, during the operator's disassembly process, as the seal between the connector and the separator body or gas pipeline gradually loosens, the high-pressure gas remaining at the connector cannot be discharged in an orderly and controllable manner. At this point, the high-pressure gas is highly likely to form a strong gas jet phenomenon the instant the seal is broken. This gas jet not only causes the disorderly diffusion of gases with specific properties such as hydrogen and oxygen, but if the hydrogen concentration reaches the explosion limit and encounters a source of ignition, it will cause a serious safety accident. Simultaneously, the high-speed gas jet may also cause physical injury to the operator, such as discomfort caused by airflow impact or the risk of component splashing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable hydrogen-oxygen separator outlet connector structure, comprising: The hydrogen-oxygen separation assembly has a hydrogen-oxygen separation tank fixedly installed on its top, and an outlet pipe fixedly connected to one side of the hydrogen-oxygen separation tank. The pressure relief structure of the connector is located on the vent pipe; The pressure relief structure of the connector includes a connecting pipe, which is bolted to the end of the outlet pipe away from the hydrogen-oxygen separator. An exhaust port is opened on the outer surface of the connecting pipe. A positioning cylinder is fixedly connected inside the exhaust port. A connecting rod is slidably connected inside the positioning cylinder. Both ends of the connecting rod slide to the outside of the positioning cylinder. A sealing plug is fixedly connected to one end of the connecting rod. The sealing plug is slidably connected to the inside of the exhaust port. Multiple vent holes are opened on the outer surface of the sealing plug. A sliding disc is fixedly sleeved on the outer surface of the connecting rod. The sliding disc is slidably connected inside the positioning cylinder. A spring is sleeved on the outside of the connecting rod and is located inside the positioning cylinder.

[0006] Preferably, the joint pressure relief structure further includes a sealing bolt and a fixing pipe. The fixing pipe is fixedly connected to the outer surface of the connecting pipe and communicates with the interior of the vent hole. The sealing bolt is threadedly connected to the interior of the fixing pipe.

[0007] Preferably, the end of the connecting rod away from the sealing plug has a positioning hole.

[0008] Preferably, one end of the spring is fixedly connected to the sliding disk, and the end of the spring away from the sliding disk is fixedly connected to the inside of the positioning cylinder.

[0009] Preferably, two limiting slide plates are fixedly connected to the side of the connecting pipe near the air outlet pipe, and two limiting grooves are opened on the side of the air outlet pipe near the connecting pipe, with the two limiting slide plates slidingly connected to the interior of the corresponding limiting grooves respectively.

[0010] Preferably, a sealing ring is fixedly connected to the side of the connecting pipe near the vent pipe, and a sealing groove is provided on the side of the vent pipe near the connecting pipe, with the sealing ring slidingly fitted inside the sealing groove.

[0011] Preferably, the cross-sections of the limiting slide plate and the limiting slide groove are both "L" shaped structures.

[0012] Preferably, the connecting pipe is internally connected to the air outlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The detachable hydrogen-oxygen separator outlet connector structure allows the sealing bolts to be unscrewed from the fixed pipe when the pressure in the outlet pipe and connecting pipe is too high. The connecting rod is then pressed down with the pressure rod, causing the connecting rod to slide and compress the spring in the positioning cylinder, which in turn causes the sealing plug to slide, exposing the vent hole to the exhaust hole. This allows the high-pressure gas to be discharged in an orderly manner, preventing gas jets from causing injury to the operator and ensuring the operator's personal safety.

It has a limit groove 5 and a sealing groove 6 for conveying gas and for installation with the connecting pipe 4.

It is used to connect to the vent pipe 3 and transport gas, and also has a pressure relief function. Limiting slide groove 5: Two of them are opened on the side of the air outlet pipe 3 near the connecting pipe 4. They are slidably connected with the corresponding limiting slide plate 7 to guide the installation of the connecting pipe 4 and prevent rotation. Sealing groove 6: It is opened on the side of the air outlet pipe 3 near the connecting pipe 4, and slides to fit the sealing ring 8. The sealing at the connection is achieved by the embedding of the sealing ring 8. Limiting slide plate 7: Fixed on the side of the connecting pipe 4 near the air outlet pipe 3, there are two in total, the cross section is "L" shaped, and it slides into the corresponding limiting slide groove 5 to achieve installation guidance and prevent horizontal rotation; Sealing ring 8: It is fixed on the side of the connecting pipe 4 near the outlet pipe 3, slides into the sealing groove 6 and slides to fit, and works with the flange bolts to achieve a reliable seal at the joint. Sealing bolt 9: It is connected to the internal thread of the fixing pipe 18. When tightened, it helps to seal the vent hole 10 to prevent gas leakage. After unscrewing, it can be used for pressure relief. Vent 10: It is opened on the outer surface of the connecting pipe 4, with a fixed positioning cylinder 12 inside, which is connected to the fixed pipe 18. The sealing plug 11 slides inside it, which is a pressure relief channel. Sealing plug 11: It is slidably connected to the vent 10, and one end is connected to the connecting rod 14. Multiple vent holes 17 are opened on the outer surface, which can block or open the vent 10 to control pressure relief. Positioning cylinder 12: It is fixedly connected inside the exhaust hole 10, and internally slides to connect the connecting rod 14 and the sliding plate 13, providing installation space for the sliding of the connecting rod 14 and the spring 15; Sliding disc 13: It is fixedly sleeved on the outer surface of the connecting rod 14 and slidably connected inside the positioning cylinder 12. One end is connected to a spring 15, which compresses or releases the spring 15 as the connecting rod 14 moves. Connecting rod 14: It is slidably connected inside the positioning cylinder 12, with both ends extending to the outside. One end is connected to the sealing plug 11, and the other end has a positioning hole 16. It is equipped with a sliding disc 13, which is used to transmit force to drive the sealing plug 11 to move. Spring 15: It is sleeved on the outside of the connecting rod 14 and located inside the positioning cylinder 12. Its two ends are connected to the sliding plate 13 and the inner wall of the positioning cylinder 12 respectively. It drives the sealing plug 11 to reset through extension and retraction. Positioning hole 16: It is opened at the end of the connecting rod 14 away from the sealing plug 11. A pressure rod can be inserted and pressed to drive the connecting rod 14 and the sealing plug 11 to move and relieve pressure. Vent hole 17: Multiple vent holes are provided on the outer surface of the sealing plug 11. When the sealing plug 11 slides to a certain position, the vent hole 10 is exposed, allowing high-pressure gas to be discharged through it to achieve pressure relief. Fixed pipe 18: Fixedly connected to the outer surface of the connecting pipe 4, communicating with the interior of the vent hole 10, and internally threaded to connect to the sealing bolt 9, providing a base for the installation and sealing of the sealing bolt 9. Example 1

[0021] like Figure 1-5 As shown, when the connecting pipe 4 is disassembled and the pressure of the vent pipe 3 and the connecting pipe 4 is too high, the sealing bolt 9 can be unscrewed from the fixed pipe 18. Then, the pressure rod is inserted into the positioning hole 16 and pressed down, thereby driving the connecting rod 14 to slide in the positioning cylinder 12 and compressing the spring 15. This causes the connecting rod 14 to drive the sealing plug 11 to slide in the vent hole 10. When the sealing plug 11 slides to a certain position, the multiple vent holes 17 on its outer surface are exposed in the vent hole 10. At this time, the high-pressure gas at the connecting pipe 4 can be discharged through the vent holes 17, realizing the pressure relief function. When the pressure in the connecting pipe 4 drops to the normal range, the pressure rod is released, and the spring 15 returns to its original state under its own elastic force, thereby driving the connecting rod 14 and the sealing plug 11 to reset and move, so that the sealing plug 11 re-seals the vent hole 10, stopping the pressure relief. The sealing bolt 9 is tightened in the fixed pipe 18, playing an auxiliary sealing role and preventing gas from leaking from the vent hole 10. Example 2

[0022] like Figure 5 As shown, the positioning hole 16 allows the operator to apply force precisely using the pressure rod. The pressure rod can have an L-shaped structure, making the depressurization process more stable and controllable, greatly improving the safety of operation and reducing the probability of accidents caused by gas jets.

[0023] Furthermore, during the installation process, the two L-shaped limiting slide plates 7 fixed on the side of the connecting pipe 4 near the outlet pipe 3 slide into the two limiting slide grooves 5 opened on the corresponding side of the outlet pipe 3. This L-shaped structure design allows the connecting pipe 4 to be accurately guided during installation and effectively prevents the connecting pipe 4 from rotating in the horizontal direction after installation, ensuring the stability of the connection. At the same time, the sealing ring 8 fixed on the side of the connecting pipe 4 near the outlet pipe 3 slides into the sealing groove 6 opened on the corresponding side of the outlet pipe 3, and the sealing ring 8 slides and adapts to the inside of the sealing groove 6. Then, the flange is connected with bolts, thereby achieving a reliable seal at the connection between the connecting pipe 4 and the outlet pipe 3 and preventing gas leakage.

[0024] When the connecting pipe 4 is disassembled and the pressure of the vent pipe 3 and the connecting pipe 4 is too high, the sealing bolt 9 can be unscrewed from the fixed pipe 18. Then, the pressure rod is inserted into the positioning hole 16 and pressed down, thereby driving the connecting rod 14 to slide in the positioning cylinder 12 and compressing the spring 15. This causes the connecting rod 14 to drive the sealing plug 11 to slide in the vent hole 10. When the sealing plug 11 slides to a certain position, the multiple vent holes 17 on its outer surface are exposed in the vent hole 10. At this time, the high-pressure gas at the connecting pipe 4 can be discharged through the vent holes 17, realizing the pressure relief function. When the pressure in the connecting pipe 4 drops to the normal range, the pressure rod is released, and the spring 15 returns to its original state under its own elastic force, thereby driving the connecting rod 14 and the sealing plug 11 to reset and move, so that the sealing plug 11 re-seals the vent hole 10, stopping the pressure relief. The sealing bolt 9 is tightened in the fixed pipe 18 to play an auxiliary sealing role and prevent gas from leaking from the vent hole 10.

[0025] Finally, remove the bolts on the flange and rotate the connecting pipe 4 to disengage the two limiting slide plates 7 from the interior of the corresponding limiting slide grooves 5, thereby facilitating the separation of the connecting pipe 4 from the air outlet pipe 3.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
