Description

Technical Field

[0001] This application relates to the field of rocket pipeline inspection, and more particularly to a gaseous waste and oil-containing purging and collection device. Background Technology

[0002] During the pre-launch testing phase of a rocket, gas needs to be blown into the pipelines to check their sealing and integrity. By observing parameters such as changes in gas pressure, it is determined whether there are any leaks or other problems in the pipelines. Before the rocket is fueled with propellant, inert gases, such as nitrogen, are usually blown into the pipelines to replace the air and other impurities in the pipelines, preventing the propellant from reacting with the air and ensuring the purity and safety of the propellant.

[0003] However, as the injected gas passes through the pipelines, oily substances and excess material in the gas, as well as from the pipes themselves, can enter gas cylinders, valves, storage tanks, and other components. Excess gas in the pipelines can affect the normal operation of the pipeline system, such as causing blockages, interfering with fluid flow, and even potentially leading to serious safety accidents. Oily substances in the pipelines can corrode pipeline materials, reducing their service life and performance. They can also affect the purity and performance of rocket propellants and other fluids, thus impacting the overall efficiency and flight performance of the rocket. Therefore, it is necessary to detect excess gas and oil in the pipelines to promptly identify potential hazards and take appropriate measures to prevent them, ensuring the reliability and safety of the rocket pipeline system.

[0004] Currently, the existing method for collecting and inspecting residual substances and oily substances involves operators wrapping a piece of cloth around the gas outlet of the pipeline to collect and inspect these substances. This method is ineffective, prone to gas leakage, and fails to effectively intercept fine particles or provide direct visual inspection of the presence of small particulate matter or oily substances in the gas. Furthermore, it carries certain risks during collection and is unsuitable for gas collection and inspection under conditions of high flow rates and high pressures.

[0005] Therefore, how to improve the detection effect of foreign matter and oily substances in gas, ensure the safety of foreign matter and oily substance collection, and expand the application conditions of gas collection and inspection are technical problems that urgently need to be solved by those skilled in the art.

[0025] like Figures 1 to 3 As shown, this application provides a gas excess and oil-containing purging collector, including: a gas inlet assembly 110, a connecting fastening assembly 120, a white silk cloth 130, a primary baffle 140, an oil-absorbing chamois 150, a secondary baffle 160, and a collection chamber assembly 170.

[0026] The collection chamber assembly 170 has an inwardly recessed collection chamber at its inlet end and a gas outflow channel connecting the collection chamber to its outlet end. A secondary baffle 160, oil-absorbing chamois 150, a primary baffle 140, and white silk cloth 130 are sequentially stacked into the collection chamber from its inlet. Both the secondary baffle 160 and the primary baffle 140 have multiple vent holes extending through both ends. Gas flows sequentially through the white silk cloth 130, the primary baffle 140, the oil-absorbing chamois 150, and... Secondary baffle 160; gas inlet assembly 110 has a gas inflow channel that runs through both ends, and the outlet end of gas inlet assembly 110 extends into the collection chamber from the inlet of the collection chamber, sequentially pressing white silk cloth 130, primary baffle 140, oil-absorbing chamois 150 and secondary baffle 160; connecting fastening assembly 120 has a fastening channel that runs through both ends, and the part of gas inlet assembly 110 near the outlet end and the part of collection chamber assembly 170 near the inlet end are fastened in the fastening channel.

This facilitates the setting of a larger diameter collecting chamber and funnel-shaped portions of the gas outflow channel and gas inflow channel near the collecting chamber. Optionally, the fastening channel of the fastening assembly 120 is stepped; the outer wall of the portion of the collecting chamber assembly 170 near the inlet end is threaded to the inner wall of the larger end of the fastening channel; the gas inlet assembly 110 passes through the smaller end of the fastening channel, and the stepped surface of the fastening channel abuts the outer wall of the gas inlet assembly 110. In this way, the collecting chamber assembly 170 and the gas inlet assembly 110 can be easily assembled together by connecting the fastening assembly 120, and can also be easily separated, facilitating the replacement of the white silk cloth 130 and the oil-absorbing chamois 150.

[0031] Alternatively, the gas inlet assembly 110, the connecting fastening assembly 120, the primary baffle 140, the secondary baffle 160, and the collecting chamber assembly 170 are all made of stainless steel 1Cr18Ni9Ti; the fixing bracket 180 and the bracket nut 190 are also made of stainless steel 1Cr18Ni9Ti.

[0032] As an example, such as Figure 4 As shown, the gas inlet assembly 110 has a gas inflow channel diameter of 10 mm, an inlet end flared opening angle of 37°, an outlet end flared opening angle of 120°, a maximum outlet diameter of 26 mm, and an outer diameter of 36 mm for the portion of the gas inlet assembly 110 near the outlet end. The outer wall of the portion of the gas inlet assembly 110 near the inlet end has an M22×1.5 external thread. The inner wall of the large end of the fastening channel of the fastening assembly 120 has an M48×1.5 internal thread, and the outer diameter of the fastening assembly 120 is 62 mm. Its outer circle has knurling to facilitate tightening of the fastening assembly 120. The white silk cloth 130 has a diameter of 36 mm. The white silk cloth has a high density and can effectively intercept 10-micron particles. Furthermore, the excess material intercepted by the white silk cloth 130 can be clearly seen with the naked eye. The primary baffle 140 is 1mm thick and 36mm in diameter, with 97 2mm diameter vents evenly arranged. The oil-absorbing chamois 150 is 36mm in diameter; it is highly absorbent, does not shed, and effectively traps oily substances in the gas. The oil-absorbing chamois 150 will exhibit a slight color difference after trapping oily substances, which is visually apparent. The secondary baffle 160 is 2mm thick and 36mm in diameter, with 97 2mm diameter vents evenly arranged. The collecting chamber assembly 170 has an inner diameter of 36 mm and a depth of 14 mm. The gas outlet channel has a diameter of 10 mm, an opening angle of 37° at its outlet flared end, an opening angle of 100° at its inlet flared end, and a maximum inlet diameter of 26 mm. The outer wall of the portion of the collecting chamber assembly 170 near the inlet end has M48×1.5 external threads. The fixing bracket 180 is a 5 mm thick plate with a 23 mm diameter fixing hole. The center of the fixing hole is 35 mm from the upper surface of the lower portion of the fixing bracket 180. The lower portion of the fixing bracket 180 has a length of 80 mm. During the collection of excess material and oily substances, the fixing bracket 180 is connected to other fasteners to secure the collector of this application. The bracket nut 190 is a 7 mm thick M22×1.5 thin nut. After assembly, the length from the inlet end of the gas inlet assembly 110 to the outlet end of the collecting chamber assembly 170 is 120 mm.

[0033] When using the gas residue and oil purging collector of this application to collect and inspect residues and oily substances in pipelines, the steps are as follows:

[0034] The first step involves placing the secondary baffle 160 (2mm thick, 2mm diameter vent hole), the oil-absorbing chamois 150, the primary baffle 140 (1mm thick, 2mm diameter vent hole), and the white silk cloth 10 into the collection chamber of the collection chamber assembly 170 in sequence.

[0035] The second step is to insert the outlet end of the gas inlet assembly 110 into the collection chamber. When inserting, the two stop blocks of the gas inlet assembly 110 are aligned with the two stop grooves of the collection chamber assembly 170.

[0036] The third step is to insert the fastening assembly 120 into the inlet end of the gas inlet assembly 110 and onto the part of the collection chamber assembly 170 near the inlet end. The M48×1.5 internal thread of the fastening assembly 120 is connected and fastened to the M48×1.5 external thread of the collection chamber assembly 170. After fastening, the fastening assembly 120 ensures that the gas inlet assembly 110, white silk cloth 130, primary baffle 140, oil-absorbing chamois 150, and secondary baffle 160 are all in a compressed state.

[0037] Fourth step, screw the first bracket nut 190 into the gas inlet assembly 110 from the inlet end and screw it to the end of the external thread of the gas inlet assembly 110;

[0038] Fifth step, insert the fixing bracket 180 into the inlet end of the gas inlet assembly 110, with the lower part of the fixing bracket 180 facing the inlet end of the gas inlet assembly 110;

[0039] Step 6: Screw the second bracket nut 190 into the gas inlet assembly 110 and onto the clamping bracket 180, and then connect the lower part of the bracket 180 to other external fasteners.

[0040] Step 7: Connect the gas collection pipeline to the inlet end of the gas inlet assembly 110;

[0041] Step 8: Open the gas collection pipeline. The gas enters the collection chamber from the inlet end of the gas inlet assembly 110. The gas passes through the white silk cloth 130, the primary baffle 140, the oil-absorbing chamois 150, and the secondary baffle 160 in sequence, and is discharged from the outlet end of the collection chamber assembly 170.

[0042] Step 9: After the required time has elapsed (the collection time and pressure depend on the quality requirements of the gas used in the process), unscrew the connecting fastening component 120, remove the collection chamber component 170, and observe whether there are any visible micro-particles or excess material in the white silk cloth 130 inside the collection chamber.

[0043] Step 10: Then remove the white silk cloth 130 and the primary baffle 140 from the collection chamber and observe whether there is any wetness or color difference on the oil-absorbing chamois 150.

[0044] Step 11: If there is no excess material on the white silk cloth 130 and no oil stains on the oil-absorbing chamois 150, then the collection and testing work is complete.

[0045] Step 12: If you observe excess material on the white silk cloth 130 and oil stains on the oil-absorbing chamois 150, replace the white silk cloth 130 and the oil-absorbing chamois 150 with new ones, and repeat the above steps to blow away and collect the residue.
