[0054] To further disclose the features and technical content of this application, please refer to the following detailed description and accompanying drawings. However, the accompanying drawings are provided for reference and illustration only and are not intended to limit this application.
[0055] Please see Figure 1This is a plan view of the detection state in this application. This application provides a concentration detection pipeline device 1 for a chemical agent, which can be connected between two agent tanks 2 and 3, so that the agent in one agent tank 2 can be detected numerically (e.g., concentration) through the concentration detection pipeline device 1, and then the detected agent can be transported to the other agent tank 3 for subsequent use. The concentration detection pipeline device 1 includes a branch pipeline 10, a first detection pipeline 11, a second detection pipeline 12, a connecting pipeline 13, and a collecting pipeline 14; wherein:
[0056] The branch pipe 10 has an inlet end 100, and a first branch end 101 and a second branch end 102 connected to the inlet end 100, and the first branch end 101 and the second branch end 102 are also connected. The inlet end 100 is used to connect to the aforementioned reagent tank 2, so that the reagent of the concentration to be detected can enter the inlet end 100 from the reagent tank 2 for detection.
[0057] The first detection line 11 has a first input terminal 110, a first output terminal 111, and a first concentration detector 112 disposed between the first input terminal 110 and the first output terminal 111. The first input terminal 110 is connected to the first branch terminal 101 of the aforementioned branch line 10, so that the reagent entering the inlet terminal 100 of the branch line 10 can pass through the first detection line 11 and be initially detected by the first concentration detector 112. A first inlet control valve 110a is provided between the first input terminal 110 and the first branch terminal 101. The first inlet control valve 110a can be a switch valve, used to control whether the connection between the first input terminal 110 and the first branch terminal 101 is maintained. Figure 1 In the embodiment shown, the first inlet control valve 110a is in an open state, allowing the agent to flow to the first concentration detector 112 for concentration detection.
[0058] The second detection pipeline 12 has a second input terminal 120, a second output terminal 121, and a second concentration detector 122 disposed between the second input terminal 120 and the second output terminal 121. The second input terminal 120 is connected to the second branch terminal 102 of the aforementioned branch pipeline 10, and a second inlet control valve 120a is provided between the second input terminal 120 and the second branch terminal 102. The second inlet control valve 120a can be a switching valve, which can be used to control whether the connection between the second input terminal 120 and the second branch terminal 102 is established. Figure 1 In the embodiment shown, the second inlet control valve 120a is closed to restrict the agent to flow only to the first concentration detector 112 for concentration detection.
[0059] This application primarily connects the connecting pipe 13 between the first detection pipe 11 and the second detection pipe 12. Specifically, the connecting pipe 13 has a first connecting end 130, a second connecting end 131, and a connecting control valve 132 disposed between the first connecting end 130 and the second connecting end 131. The first connecting end 130 is connected to the first output end 111 of the first detection pipe 11, and the second connecting end 131 is connected to the second input end 120 of the second detection pipe 12, so that the reagent for the first concentration detection can enter the second detection pipe 12 through the connecting control valve 132 of the connecting pipe 13, and be detected a second time by the second concentration detector 122. The connecting control valve 132 can be a switch valve, used to control whether the connection between the first detection pipe 11 and the second detection pipe 12 is established. Figure 1 In the embodiment shown, the connection control valve 132 is in an open state, allowing the agent to flow to the second concentration detector 122 for concentration detection.
[0060] Furthermore, the manifold 14 has an outlet end 140, and a first manifold 141 and a second manifold 142 connected to and gathered at the outlet end 140. The first manifold 141 is connected to the first output end 111 of the first detection conduit 11, and a first outlet control valve 111a is provided between the first manifold 141 and the first output end 111. The first outlet control valve 111a can be a switch valve, used to control whether the connection between the first manifold 141 and the first output end 111 is established. Figure 1 In the illustrated embodiment, the first outlet control valve 111a is closed to prevent the drug from being directly delivered to another drug tank 3 without passing through the second concentration detector 122. Furthermore, the second manifold 142 is connected to the second output terminal 121 of the aforementioned second detection pipeline 12, and a second outlet control valve 121a is provided between the second manifold 142 and the second output terminal 121. This second outlet control valve 121a can be a switching valve, used to control whether the connection between the second manifold 142 and the second output terminal 121 is maintained. Figure 1 In the embodiment shown, the second outlet control valve 121a is in the open state to allow the reagent that has passed the secondary concentration detection to be delivered to another reagent tank 3 for subsequent use.
[0061] And in Figure 1 In the state shown, the first inlet control valve 110a, the connecting control valve 132 and the second outlet control valve 121a are in the open state, while the second inlet control valve 120a and the first outlet control valve 111a are in the closed state, thus forming a detection loop.
[0062] In summary, the concentration detection pipeline device for the chemical reagents described above can be obtained.
[0063] Accordingly, Figure 2 and Figure 3 As shown, through the above design, this application can also be used independently as any one of the detection lines. Figure 2 As shown, by closing the second inlet control valve 120a, the second outlet control valve 121a, and the connecting control valve 132, which are connected to the second detection pipeline 12, and opening the first inlet control valve 110a and the first outlet control valve 111a, which are connected to the first detection pipeline 11, the agent can be supplied from the agent tank 2 to the other agent tank 3 using only the first detection pipeline 11; and if Figure 3 As shown, by closing the first inlet control valve 110a, the first outlet control valve 111a, and the connecting control valve 132 that are connected to the first detection pipeline 11, and opening the second inlet control valve 120a and the second outlet control valve 121a that are connected to the second detection pipeline 12, the agent can be supplied from the agent tank 2 to another agent tank 3 using only the second detection pipeline 12.
[0064] Also, such as Figure 4 As shown, this application may also branch off to a first discharge end 113 at the first input end 110 of the first detection pipeline 11, and the first discharge end 113 is provided with a first discharge control valve 113a. The first discharge control valve 113a may be a switch valve, which can control whether the agent in the first detection pipeline 11 is discharged. At the same time, the second input end 120 of the second detection pipeline 12 may branch off to a second discharge end 123, and the second discharge end 123 is provided with a second discharge control valve 123a. The second discharge control valve 123a may be a switch valve, which can also control whether the agent in the second detection pipeline 12 is discharged.
