Description

Technical Field

[0001] This invention relates to the field of radioactive waste treatment technology, and in particular to a remotely replaceable valve device and a method for remotely replacing valves. Background Technology

[0002] In the field of radioactive waste treatment engineering, valves are commonly used equipment. They are typically designed to be located outside the radioactive hot chamber and not circulated with radioactive media to ensure their service life. However, in certain special conditions, such as high-level radioactive waste vitrification treatment projects, valves are required at both the inlet and outlet of the washing liquid circulation pump in the exhaust gas treatment system. Valve types include ball valves and check valves. These valves have a limited service life in radioactive environments, especially since their sealing components cannot withstand high-dose radiation. Therefore, it is necessary to enable valves to be replaced remotely in radioactive environments.

[0003] However, in existing technologies, valves in radioactive environments are mostly installed in pipelines via threads, making it difficult to disassemble and replace valves remotely using robotic arms. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art by providing a remotely replaceable valve device and a method for remotely replacing valves, which can realize the overall remote replacement of the second connecting component and the valve.

The clamping assembly is disposed on the first clamping plate and the second clamping plate, and is used to clamp the second clamping plate onto the first clamping plate under the operation of the robot, and to release the second clamping plate from the first clamping plate. After the two second clamping plates on the two valve jumpers are pressed onto the corresponding first clamping plates, the second sealing joint is pressed onto the first sealing joint, so that the second inlet end is pressed onto the first outlet end and connected to each other; after the two second clamping plates on the two valve jumpers are released from the corresponding first clamping plates, the robot arm can remove the two second clamping plates and the valve from the two first clamping plates.

[0008] In some embodiments, the clamping assembly includes a bolt and a nut; the bolt is movably disposed on the second clamping plate, and the nut is disposed at the bottom of the first clamping plate; the bolt can be tightened onto the nut after passing through the second clamping plate and the first clamping plate from top to bottom under the operation of the robot arm, so as to clamp the second clamping plate onto the first clamping plate.

[0010] In some embodiments, the second clamping plate is provided with a gripping block; the robotic arm can grip the gripping part and then move the nut.

[0011] In some embodiments, a positioning pin is provided on the lower surface of the second pressing plate, and a positioning hole is provided on the upper surface of the first pressing plate, wherein the positioning pin is adapted to the positioning hole.

[0027] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are enlarged for clarity. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0028] Example 1: like Figure 1 As shown, this embodiment of the invention provides a remotely replaceable valve device, which is applied in a hot chamber plant to enable remote replacement of valves within the hot chamber plant.

[0029] like Figure 1 As shown, the remotely replaceable valve device includes a valve jumper and a valve 3. The valve jumper is installed inside the hot chamber plant and includes a first connecting component 1, a second connecting component 2, and a clamping component 4. The first connecting component 1 has a first inlet end and a first outlet end; the first inlet end is connected to a hot chamber pipeline inside the hot chamber plant. The second connecting component 2 has a second inlet end and a second outlet end, and is movable under the operation of a robotic arm; the second inlet end can be connected to the first outlet end after clamping the first outlet end. The clamping component 4 is installed on the first connecting component 1 and the second connecting component 2, and is used to clamp the second connecting component 2 onto the first connecting component 1 under the operation of the robotic arm, and to release the second connecting component 2 from the first connecting component 1. Valve 3 is mounted on the second connecting component 2 and connected to the second outlet end. After the second connecting component 2 is pressed against the first connecting component 1, the second inlet end is pressed against the first outlet end and connected to each other, so that valve 3 can be connected to the hot chamber pipe. After the second connecting component 2 is released from the first connecting component 1, the robot can remove the second connecting component 2 from the first connecting component 1 to replace the second connecting component 2 and valve 3 at the second outlet end as a whole.

[0030] For example, the hot chamber piping in the hot chamber plant can be the piping at the inlet and outlet of the scrubbing liquid circulation pump in the exhaust gas treatment system.

[0031] For example, the robotic arm can move the second connecting component 2 so that the second connecting component 2 is opposite to the first connecting component 1.

[0032] For example, such as Figure 1 As shown, the first connecting component 1 is located below the second connecting component 2, the first inlet end is located at the lower part of the first connecting component 1, and the first outlet end is located at the upper part of the first connecting component 1. The second inlet end is located at the lower part of the second connecting component 2, and the second outlet end is located at the upper part of the second connecting component 2. The second inlet end is opposite to the first outlet end.

[0033] Alternatively, the first connecting component 1 and the second connecting component 2 can be arranged sequentially along the horizontal direction.

[0034] The robotic arm can move the second connecting component 2 onto the first connecting component 1, or remove the second connecting component 2 from the first connecting component 1. The valve 3 is mounted on the second connecting component 2, therefore the valve 3 can move synchronously with the second connecting component 2.

[0035] For example, valve 3 can be a ball valve, check valve, pressure reducing valve, gate valve, or butterfly valve, etc.

[0036] like Figure 1 As shown, valve 3 is connected to the second outlet end through the first pipe 18. The first pipe 18 can be a rigid pipe.

[0037] With the above setup, after the robotic arm presses the second connecting component 2 onto the first connecting component 1, the valve 3 can be connected to the hot chamber pipe.

[0038] like Figure 1 As shown, when valve 3 is damaged, the robotic arm can operate the clamping assembly 4 to loosen the second connecting assembly 2 from the first connecting assembly 1, so that the second inlet end and the first outlet end are no longer connected, thus disconnecting valve 3 from the hot chamber pipeline; at this time, the robotic arm can remove the second connecting assembly 2 and valve 3 as a whole from the first connecting assembly 1, and move the second connecting assembly 2 and valve 3 as a whole to a temporary storage position.

[0039] Afterwards, the newly replaced second connecting component 2 and valve 3 can be moved onto the first connecting component 1 by a robotic arm. The robotic arm operates the clamping component 4 to press the second connecting component 2 onto the first connecting component 1, so that the newly replaced valve 3 can be connected to the hot chamber pipeline again. Thus, the robotic arm can remotely replace the second connecting component 2 and valve 3 as a whole.

[0040] During normal use, valve 3 can be opened or closed by rotating the arm of the robotic arm.

[0041] Therefore, the remotely replaceable valve device provided in this embodiment of the invention, by setting a first connecting component 1 and a second connecting component 2, wherein the first connecting component 1 has a first inlet end and a first outlet end, and the second connecting component 2 has a second inlet end and a second outlet end, connects the first inlet end to the hot chamber pipeline in the hot chamber plant, and the second inlet end can be connected to the first outlet end after being pressed together, and the valve 3 is connected to the second outlet end, so that the hot chamber pipeline is connected to the valve 3 after the second inlet end is pressed together with the first outlet end. By enabling the second connecting component 2 to move under the operation of a robotic arm, the robotic arm can move the second connecting component 2 onto the first connecting component 1, or remove the second connecting component 2 from the first connecting component 1. By setting a pressing component 4, the robotic arm can press the second connecting component 2 onto the first connecting component 1, and release the second connecting component 2 from the first connecting component 1. Therefore, when the valve 3 is damaged, the robotic arm can operate the pressing component 4 to release the second connecting component 2 from the first connecting component 1, and remove the second connecting component 2 and the valve 3 as a whole from the first connecting component 1 by moving the second connecting component 2. The robotic arm can then move the newly replaced second connecting component 2 and valve 3 onto the first connecting component 1, and operate the clamping component 4 to clamp the second connecting component 2 onto the first connecting component 1, so that the newly replaced valve 3 is connected to the hot chamber pipe again, thereby completing the overall remote replacement of the second connecting component 2 and valve 3 through the robotic arm.

[0042] In some embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, there is one valve jumper. The first connecting assembly 1 includes a first clamping plate 5 and multiple first sealing joints 6; the multiple first sealing joints 6 are all disposed through the first clamping plate 5, and the two ends of the first sealing joint 6 form a first inlet end and a first outlet end, respectively. The second connecting assembly 2 includes a second clamping plate 7 and multiple second sealing joints 8; the second clamping plate 7 is movable under the operation of a robot; the multiple second sealing joints 8 are all disposed through the second clamping plate 7, and the multiple second sealing joints 8 are arranged one-to-one with the multiple first sealing joints 6, and the two ends of the second sealing joints 8 form a second inlet end and a second outlet end, respectively. The valve 3 is disposed on the second clamping plate 7, and the two ends of the valve 3 are respectively connected to the two second outlet ends on the valve jumper. The clamping assembly 4 is disposed on the first clamping plate 5 and the second clamping plate 7, and is used to clamp the second clamping plate 7 onto the first clamping plate 5 under the operation of the robot, and to release the second clamping plate 7 from the first clamping plate 5. After the second pressing plate 7 is pressed onto the first pressing plate 5, multiple second sealing joints 8 are pressed onto the corresponding first sealing joints 6, so that multiple second inlet ends are pressed onto the corresponding first outlet ends and connected to each other; after the second pressing plate 7 is released from the first pressing plate 5, the robot can remove the second pressing plate 7 and valve 3 from the first pressing plate 5.

[0043] For example, the first clamping plate 5 and the second clamping plate 7 can be two mating flanges.

[0044] For example, such as Figure 4 As shown, the first sealing joint 6 is a sealing pipe joint, and the second sealing joint 8 is a sealing pin joint.

[0045] For example, the first sealing joint 6 on the first clamping plate 5 is connected to the hot chamber pipe by welding.

[0046] For example, such as Figure 3 As shown, the first inlet end is located at the lower end of the first sealing joint 6, and the first outlet end is located at the upper end of the first sealing joint 6; the second inlet end is located at the lower end of the second sealing joint 8, and the second outlet end is located at the upper end of the second sealing joint 8. The surface roughness of the contact surface between the second inlet end and the first outlet end is not higher than Ra0.8.

[0047] For example, the number of first sealing joints 6 on the first pressing plate 5 can be two, three, or four, etc. The number of second sealing joints 8 on the second pressing plate 7 is the same as the number of first sealing joints 6, and the positions of the multiple second sealing joints 8 on the second pressing plate 7 are the same as the positions of the multiple first sealing joints 6 on the first pressing plate 5, so that after the second pressing plate 7 is pressed against the first pressing plate 5, the multiple second sealing joints 8 are pressed against the corresponding multiple first sealing joints 6.

[0048] like Figure 1As shown, both ends of valve 3 are connected to the hot chamber pipes via a valve jumper. At this time, the two first inlet ends of the valve jumper are connected to the two hot chamber pipes, and the two hot chamber pipes are interconnected through valve 3. When the robotic arm moves the second clamping plate 7, it can move the second clamping plate 7 and valve 3 as a whole.

[0049] When valve 3 needs to be replaced, the robotic arm operates the clamping assembly 4 on the valve jumper to release the second clamping plate 7 from the first clamping plate 5. This allows the robotic arm to remotely remove and move the second clamping plate 7 and valve 3 as a whole. The robotic arm can then move the newly replaced second clamping plate 7 and valve 3 onto the second clamping plate 7 and operate the clamping assembly 4 to press the second clamping plate 7 against the first clamping plate 5. This connects both ends of valve 3 to the two hot chamber pipes via the valve jumper, enabling remote replacement of valve 3 and the second clamping plate 7 as a whole.

[0050] In some embodiments, such as Figure 5 and Figure 6 As shown, there are two valve jumpers. The first connecting assembly 1 includes a first clamping plate 5 and at least one first sealing joint 6; the first sealing joint 6 is disposed through the first clamping plate 5, and its two ends form a first inlet end and a first outlet end, respectively. The second connecting assembly 2 includes a second clamping plate 7 and at least one second sealing joint 8; the second clamping plate 7 is movable under the operation of a robot; the second sealing joint 8 is disposed through the second clamping plate 7, and its two ends form a second inlet end and a second outlet end, respectively. Figure 5 and Figure 6 As shown, valve 3 is simultaneously mounted on the second clamping plates 7 of both valve bridges, with both ends of valve 3 connected to the second outlet ends of the two valve bridges respectively. Clamping assembly 4 is mounted on the first clamping plate 5 and the second clamping plate 7, used to clamp the second clamping plate 7 onto the first clamping plate 5 under the operation of the robotic arm, and to release the second clamping plate 7 from the first clamping plate 5. After the two second clamping plates 7 on the two valve bridges are clamped onto their corresponding first clamping plates 5, the second sealing joint 8 is clamped onto the first sealing joint 6, so that the second inlet end is clamped onto the first outlet end and connected to each other; after the two second clamping plates 7 on the two valve bridges are released from their corresponding first clamping plates 5, the robotic arm can remove the two second clamping plates 7 and valve 3 from the two first clamping plates 5.

[0051] For example, in two valve jumpers, one valve jumper has one first sealing joint 6 and the other valve jumper has one second sealing joint 8; or, one valve jumper has one first sealing joint 6 and the other valve jumper has multiple second sealing joints 8; or, one valve jumper has multiple first sealing joints 6 and the other valve jumper has one second sealing joint 8.

[0052] Combination Figure 5 and Figure 6 Under any circumstances, both ends of valve 3 can be connected to the two second outlet ends on the two valve jumpers, and the two hot chamber pipes can be connected to valve 3 through the corresponding first inlet on the two valve jumpers.

[0053] like Figure 5 and Figure 6 As shown, when there are multiple first sealing joints 6 and multiple second sealing joints 8 in the two valve jumpers, multiple types and sizes of valves 3 can be installed on the two valve jumpers at the same time. This is suitable for situations where multiple hot chamber pipelines are arranged close together and all need to be equipped with valves 3 that can be replaced remotely.

[0054] like Figure 5 and Figure 6 As shown, when valve 3 needs to be replaced, the robotic arm sequentially operates the clamping components 4 on the two valve bridges, causing the second clamping plates 7 in both valve bridges to loosen from their corresponding first clamping plates 5. This allows the robotic arm to remove the two second clamping plates 7 along with valve 3. The robotic arm can then move the two newly replaced second clamping plates 7 and valve 3 onto the second clamping plates 7 in the two valve bridges, and sequentially operate the clamping components 4 on the two valve bridges to clamp the two second clamping plates 7 onto their corresponding first clamping plates 5. This connects both ends of valve 3 to the two hot chamber pipes through the two valve bridges, enabling remote disassembly and replacement of valve 3 and the two second clamping plates 7.

[0055] For example, in two valve jumpers, two second clamping plates 7 can be fixed together by a fixing rod to maintain the synchronous movement of the two second clamping plates 7.

[0056] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the clamping assembly 4 includes a bolt 9 and a nut 10; the bolt 9 is movably mounted on the second clamping plate 7, and the nut 10 is mounted on the bottom of the first clamping plate 5; the bolt 9 can be tightened onto the nut 10 after passing through the second clamping plate 7 and the first clamping plate 5 from top to bottom under the operation of the robot arm, so as to press the second clamping plate 7 onto the first clamping plate 5.

[0057] For example, both the second clamping plate 7 and the first clamping plate 5 are provided with through holes that allow the bolt 9 to pass through. After the bolt 9 passes through the through holes on the second clamping plate 7 and the first clamping plate 5, it is threadedly connected to the nut 10.

[0058] For example, the bottom of the first clamping plate 5 is provided with a groove into which the nut 10 can slide, and the nut 10 is positioned at the bottom of the first clamping plate 5 after sliding into the groove.

[0059] For example, the robotic arm can operate an electric wrench to tighten bolt 9, and the tightening torque of the electric wrench is approximately 120 N·m.

[0060] For example, a sleeve 19 is provided on the second clamping plate 7, and the bolt 9 also passes through the sleeve 19 to raise the screwing position of the bolt 9, which facilitates the operation of the electric wrench.

[0061] After the robotic arm loosens the bolt 9 from the nut 10, the second clamping plate 7 can be removed from the first clamping plate 5.

[0062] For example, the clamping assembly 4 may also include a quick-release buckle and a quick-release hook. The quick-release buckle is disposed on the first clamping plate 5, and the quick-release hook is disposed on the second clamping plate 7. The robot arm can hook the quick-release buckle onto the quick-release hook and clamp it to press the second clamping plate 7 onto the first clamping plate 5, or to release the second clamping plate 7 from the first clamping plate 5.

[0063] In some embodiments, the nut 10 is provided with a gripping part. The robot arm can grasp the gripping part and move the nut (10).

[0064] For example, the gripping part can be a hook welded to the nut 10, and the robot arm can grip the hook to remove the nut 10 from the bottom of the first clamping plate 5 for replacement.

[0065] With the above settings, after the nut 10 wears out from long-term use, the robot arm can easily replace the nut 10 remotely.

[0066] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, a gripping block 11 is provided on the second clamping plate 7. The robotic arm can grip the gripping block 11 to drive the second clamping plate 7 to move.

[0067] For example, the gripping block 11 is welded to the second clamping plate 7. The gripping block 11 is provided with gripping grooves for the robotic arm to grip.

[0068] The above settings facilitate the movement of the second clamping plate 7 by the robotic arm.

[0069] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the lower surface of the second pressing plate 7 is provided with a positioning pin 12, and the upper surface of the first pressing plate 5 is provided with a positioning hole, and the positioning pin 12 is adapted to the positioning hole.

[0070] For example, there can be two positioning pins 12, and the two positioning pins 12 have different lengths. Correspondingly, there can also be two positioning holes. During the process of the robot moving the second pressing plate 7 onto the first pressing plate 5, the robot first inserts the longer positioning pin 12 into the corresponding positioning hole, and then inserts the shorter positioning pin 12 into place. After that, the second pressing plate 7 continues to move downward, and the precise positioning between the second pressing plate 7 and the first pressing plate 5 is achieved through the two positioning pins 12.

[0071] In some embodiments, the first connecting component 1 has a plurality of first sealing joints 6; the second connecting component 2 has a plurality of second sealing joints 8. The first pressing plate 5 is circular in shape, and the plurality of first sealing joints 6 are evenly arranged along the circumference of the first pressing plate 5; the second pressing plate 7 is circular in shape, and the plurality of second sealing joints 8 are evenly arranged along the circumference of the second pressing plate 7.

[0072] With the above arrangement, the space on the second pressing plate 7 and the first pressing plate 5 can be fully utilized to arrange more first sealing joints 6 and second sealing joints 8, and to disperse the force exerted by the first sealing joint 6 on the first pressing plate 5 and the force exerted by the second sealing joint 8 on the second pressing plate 7.

[0073] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the first connecting component 1, the second connecting component 2, and the clamping component 4 form a jumper pair 13; there are multiple jumper pairs 13, which are arranged sequentially, and the first clamping plate 5 and the second clamping plate 7 in the multiple jumper pairs 13 are arranged alternately in sequence; the second clamping plate 7 of the previous valve jumper is fixedly connected to the first clamping plate 5 of the next valve jumper; the second outlet end of the previous valve jumper is connected to the first inlet end of the next valve jumper through the second pipe 14; the hot chamber pipe is connected to the first inlet end of the foremost jumper pair 13; the valve 3 is connected to the second outlet end of the last jumper pair 13.

[0074] For example, the number of jumper pairs 13 can be two, three, or more, etc.

[0075] like Figure 1 , Figure 2 and Figure 3As shown in the figure, two jumper pairs 13 are displayed. The two jumper pairs 13 are arranged sequentially from top to bottom. The second clamping plate 7 in the lower jumper pair 13 is fixedly connected to the first clamping plate 5 in the upper jumper pair 13 via a fixing rod 21, forming an intermediate replacement module. The first inlet end of the lower jumper pair 13 is connected to the hot chamber pipe, and the second outlet end of the upper jumper pair 13 is connected to the valve 3.

[0076] For example, such as Figure 1 , Figure 2 and Figure 3 As shown, the number of jumpers 13 is set to two, and the number of intermediate replacement modules is one. In daily use, when replacing valve 3, only the second clamping plate 7 above the intermediate replacement module is replaced as a whole. After long-term use and multiple replacements of the second clamping plate 7, the sealing contact surface between the first sealing joint 6 in the intermediate replacement module and the second sealing joint 8 above it will wear down. In this case, the intermediate replacement module can be replaced as a whole by a robotic arm (the replacement process is similar to that of replacing the valve) to ensure the sealing performance between the first sealing joint 6 and the second sealing joint 8.

[0077] The weight and position of the gripping block 11 in the intermediate replacement module can be adjusted according to the center of gravity of the intermediate replacement module so that the center of gravity of the intermediate replacement module is located on the center line of the entire intermediate replacement module.

[0078] The above settings ensure the sealing performance of the remotely replaceable valve device and maintain its normal operation for an extended period of time.

[0079] In some embodiments, such as Figure 1 As shown, the remotely replaceable valve device also includes a fixing component 15. The fixing component 15 is used to fix the first clamping plate 5.

[0080] For example, the fixing components are fixed to the wall of the hot chamber plant.

[0081] The above settings can fix the position of the remotely replaceable valve device, maintaining its stability during operation.

[0082] In some embodiments, such as Figure 1 , Figure 7 and Figure 8 As shown, the fixing assembly 15 includes a fixing bracket 16 and a pin 17. The fixing bracket 16 has a mounting hole whose dimensions are adapted to the dimensions of the first clamping plate 5; the first clamping plate 5 is engaged in the mounting hole. The pin 17 passes through the fixing bracket 16 and extends into the first clamping plate 5.

[0083] For example, the mounting bracket 16 is formed by welding a support and a support plate 20, with the support welded to an embedded plate in the hot chamber. Mounting holes are formed in the support plate 20.

[0084] For example, the number of pins 17 is two.

[0085] With the above settings, the first pressing plate 5 can be fixed to the fixing frame 16 by the plug pin 17. Compared with welding the first pressing plate 5 to the fixing frame 16, the dimensional deviation of the first pressing plate 5 during the welding process can be avoided.

[0086] It should be noted that the main components (such as the second clamping plate 7) of the remotely replaceable valve device provided in this embodiment of the invention can all be made of stainless steel to improve the radiation resistance of the remotely replaceable valve device.

[0087] After the initial installation of the aforementioned remotely replaceable valve device, the steps for replacing valve 3 are as follows: 1. When valve 3 needs to be replaced over a long distance, use a robotic arm to carry an electric wrench to tighten bolt 9 until bolt 9 is detached from nut 10; 2. The second clamping plate 7 and valve 3 are removed from the first clamping plate 5 by the gripping groove on the gripping block 11 of the second clamping plate 7 using a robotic arm, and then transported as a whole to the storage location (e.g., maintenance station). 3. The robotic arm picks up the new second clamping plate 7 and valve 3, moves them above the first clamping plate 5, positions them using two positioning pins 12, and places them in place; 4. Using a robotic arm carrying an electric wrench, tighten the bolt 9 on the second clamping plate 7 and tighten the bolt 9 onto the nut 10; 5. If an intermediate replacement module is provided, the intermediate replacement module shall be replaced when the sealing surface of the first sealing joint 6 of the intermediate replacement module is worn. The replacement method of the intermediate replacement module is the same as that of the second pressure plate 7 and valve 3. 6. When the threads of nut 10 wear out after multiple replacements, a robotic arm can be used to grip the gripping part on nut 10, pull it out horizontally, and then replace it with a new nut 10 and install it.

[0088] The advantages of the remotely replaceable valve device provided in this embodiment of the invention are as follows: 1) It enables remote replacement of the entire valve 3 in a radioactive environment; 2) The sealing method of the valve device's sealing structure that can be remotely replaced adopts a hard sealing method using sealing pin joints and sealing pipe joints, which is not affected by radiation, acid, or other environmental factors. 3) Remote replacement can be completed via a robotic arm inside the heated chamber, making operation simple and convenient; 4) For long-distance installation, the positioning method is simple and reliable; 5) Multiple intermediate replacement modules can be set up as needed, so that valve 3 can be replaced hundreds of times and the reliable sealing of the remotely replaceable valve device can still be guaranteed.

[0089] Example 2: This invention provides a method for remotely replacing a valve. The method uses the remotely replaceable valve device in Embodiment 1, and the method includes steps S100-S400.

[0090] S100, the robotic arm operates the clamping component 4 to release the second connecting component 2 from the first connecting component 1.

[0091] At this time, the second inlet end is no longer connected to the first outlet end, and the second connecting component 2 is in a state where it can be removed from the first connecting component 1.

[0092] S200, the robotic arm removes the second connecting component 2 from the first connecting component 1, causing the second connecting component 2 to drive the valve 3 to be removed from the first connecting component 1.

[0093] Valve 3 is mounted on the second connecting assembly 2, so removing the second connecting assembly 2 allows for the simultaneous removal of valve 3. The removed second connecting assembly 2 and valve 3 can then be placed in a storage location (e.g., a maintenance station).

[0094] S300, the robotic arm moves the newly replaced second connecting component 2 and valve 3 onto the first connecting component 1.

[0095] S400, the robotic arm operates the clamping assembly 4 to press the second connecting assembly 2 onto the first connecting assembly 1, so that the second inlet end is pressed onto the first outlet end and they are connected to each other, so that the valve 3 can be connected to the hot chamber pipeline.

[0096] For example, valve 3 can be a valve applied at the inlet and outlet of the scrubbing liquid circulation pump in the exhaust gas treatment system.

[0097] Using the above method, valve 3 can be replaced remotely via a robotic arm when it malfunctions.

[0098] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
