Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, in particular to an oxygen pipeline replacement and purge structure. Background Art

[0002] Oxygen pipeline is one of the main products of air separation equipment and is a gaseous oxygen transportation equipment. Due to the special physical and chemical properties of oxygen, the safety of oxygen pipeline during operation plays an important role in the stable operation of air separation equipment.

[0003] During the installation of pipeline equipment, various impurities, such as welding slag, dust, etc., will inevitably be brought into the equipment and pipelines during installation. They must be removed before commissioning to avoid valve action and unexpected equipment failure during operation.

[0004] Therefore, after the oxygen pipeline has passed the degreasing cleaning and pressure test, it must be purged and replaced to clean the impurities inside the pipeline and the possible flammable and explosive gases, to ensure the cleanliness of the inside of the pipeline and ensure the safety of the oxygen pipeline when it is put into operation.

[0005] At present, the factory adopts the method of manually controlling the purge pressure to purge and replace the oxygen pipeline. The pressure fluctuates greatly, which increases the purge time. In addition, the purge results cannot be analyzed in time during the purge, and the purge effect cannot be fed back in real time, resulting in low efficiency.

[0006] Therefore, we propose an oxygen pipeline replacement purge structure to solve the existing problems. Utility Model Content

[0007] The utility model aims to solve the problems existing in the background technology and proposes an oxygen pipeline replacement and purge structure.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oxygen pipeline replacement and purge structure, comprising a floor, a distribution box, a panel, a pressure sensor and a pipe body, the upper surface of the floor is provided with a panel, a pressure sensor is embedded in the panel, a touch plate is fixed to the working end of the pressure sensor, a pressure control valve is installed at one end of the pipe body through a flange, an air blowing pipe is fixed to the input end of the pressure control valve, a butterfly valve is installed at the other end of the pipe body through a flange, and the output end of the butterfly valve is facing the touch plate.

[0009] Preferably, a distribution box is installed on the upper surface of the floor;

[0010] The control elements inside the distribution box are electrically connected to the pressure sensor, the butterfly valve, the pressure control valve and the pump body through wires.

[0011] Preferably, a pump body is mounted on the upper surface of the distribution box by bolts;

[0012] An air filter assembly is installed at the suction end of the pump body;

[0013] The discharge end of the pump body is communicated with the air blowing pipe.

[0014] Preferably, a support seat is installed on the lower surface of the floor;

[0015] There are four support bases in total, and the positions of the four support bases are distributed in a rectangular array on the lower surface of the floor.

[0016] Preferably, a matching installation groove is provided at a corresponding position on the upper outer wall of the panel;

[0017] The pressure sensor is fixed at the bottom end of the inner wall of the installation slot, and the touch panel covers the slot opening of the installation slot.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] During use, the oxygen pipeline replacement purge structure of the utility model can be moved to the installation position of the oxygen pipeline, and the purge gas inlet and discharge port of the oxygen pipeline body are provided with a pressure control valve and a butterfly valve;

[0020] When the pump is working, high-pressure airflow is generated and enters the pipe through the air blowing pipe. The pressure control valve controls and stabilizes the blowing pressure, achieving the purpose of continuous blowing. The butterfly valve can also be adjusted to increase the pressure in the pipe and control the rapid opening and closing of the valve at the discharge point, so that the impurities in the pipe are discharged from the discharge port along with the airflow, achieving the purpose of explosive blowing.

[0021] During the purging process, the airflow carries the impurities and sprays them onto the touch plate. Due to the different pressures of the airflow impacting the touch plate and the solid impurities impacting the touch plate, the signal received by the pressure sensor fluctuates greatly, indicating that there are still impurities inside the tube body at this time. When the signal received by the pressure sensor is in a stable state, it means that the impurities inside the tube body have been purged clean.

[0022] The utility model is provided with a detection structure at the discharge point, and the purge result is analyzed in time during purge, and the purge effect is fed back in real time, so that the pipeline purge effect can be monitored in real time and the purge efficiency is improved.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1

[0031] like Figure 1-Figure 4 As shown, the utility model proposes an oxygen pipeline replacement and purge structure, comprising a floor 1, a distribution box 2, a panel 4, a pressure sensor 5 and a tube body 7. The upper surface of the floor 1 is provided with a panel 4, and the pressure sensor 5 is embedded and installed in the panel 4. A touch plate 12 is fixed to the working end of the pressure sensor 5. A pressure control valve 8 is installed at one end of the tube body 7 through a flange, and an air blowing pipe 9 is fixed to the input end of the pressure control valve 8. A butterfly valve 6 is installed at the other end of the tube body 7 through a flange, and the output end of the butterfly valve 6 is facing the touch plate 12.

[0032] Based on Example 1: During use, the oxygen pipeline replacement purge structure of the utility model can be moved to the installation position of the oxygen pipeline, and the purge gas inlet and discharge port of the oxygen pipeline body 7 are provided with a pressure control valve 8 and a butterfly valve 6;

[0033] The pump body 11 generates high-pressure airflow through the air blowing pipe 9 into the pipe body 7, and the purge pressure is controlled and stabilized by the pressure control valve 8, so as to achieve the purpose of continuous purge. The butterfly valve 6 can also be adjusted to increase the pressure in the pipeline, and the rapid opening and closing of the valve at the discharge point can be controlled to discharge impurities in the pipeline from the discharge port along with the airflow, so as to achieve the purpose of explosive purge.

[0034] During the purging process, the airflow carries impurities and sprays them onto the touch plate 12. Since the pressures of the airflow impacting the touch plate 12 and the solid impurities impacting the touch plate 12 are different, the signal received by the pressure sensor 5 fluctuates greatly, indicating that there are still impurities inside the tube body 7 at this time. When the signal received by the pressure sensor 5 is in a stable state, it means that the impurities inside the tube body 7 have been purged clean.
