Description

Technical Field

[0001] This application belongs to the field of liquid phase sampling technology, specifically a liquid phase sampling device. Background Technology

[0002] The liquid phase refers to a substance in a liquid state, where there is only liquid and no solid or gas phase in the system. When sampling the liquid phase inside the pipeline, a sampling device is used. The sampling device consists of a sampling container and a container valve pipe connected to the liquid phase pipeline. When the container valve pipe is opened, the liquid phase can be transported to the sampling container for sampling.

[0003] Existing liquid phase sampling devices cannot effectively control the overall sampling volume during sampling. The sampling container lacks a volume control mechanism, making it inconvenient to take the corresponding volume. In addition, excessively high overall pressure also causes sampling inconvenience. Utility Model Content

[0004] The purpose of this application is to provide a liquid phase sampling device in order to solve the problem that the existing liquid phase sampling devices mentioned above cannot effectively control the sampling capacity and excessive sampling pressure during sampling.

[0005] The technical solution adopted in this application is as follows: A liquid phase sampling device includes a liquid phase pipeline and a sampling valve cover. The sampling valve cover is installed and connected to the outer end of the liquid phase pipeline. An upper container is fixed to the lower end of the sampling valve cover. A sampling control mechanism is installed in the middle of the lower end of the upper container. A lower container is installed on the periphery of the sampling control mechanism on the upper container. A bottom solenoid valve is installed at the lower end of the lower container. The sampling valve cover, the upper container, the bottom solenoid valve, and the sampling control mechanism are electrically connected to the external central processing panel box through a connecting line.

[0006] By adopting the above technical solution, the sampling valve cover is installed and connected to the outer end of the liquid phase pipeline. When the sampling valve cover opens the internal flow channel, the liquid phase substance inside the liquid phase pipeline is transported through the sampling valve cover, which then transports the liquid phase medium to the upper container tank. After the sampling valve cover closes, the pressure in the upper container tank is not as high as the pressure inside the liquid phase pipeline, thus facilitating personnel sampling. A lower container tank is installed on the periphery of the sampling control mechanism on the upper container tank. The sampling control mechanism can sample the capacity inside the lower container tank. A bottom solenoid valve is installed at the lower end of the lower container tank, and the sampled liquid phase medium in the lower container tank can be discharged and collected through the bottom solenoid valve.

[0007] In a preferred embodiment, the sampling control mechanism includes a first electric telescopic cylinder, a corrugated telescopic tube, and a blocking disc. The lower end of the telescopic rod of the first electric telescopic cylinder is equipped with a blocking disc, and the upper end of the blocking disc is equipped with a corrugated telescopic tube. The first electric telescopic cylinder and the corrugated telescopic tube are mounted and connected to the upper container tank.

[0008] By adopting the above technical solution and through the sampling control mechanism structure, the sampling capacity inside the lower container can be adjusted by raising and lowering it.

[0009] In a preferred embodiment, the corrugated telescopic tube and the blocking disc are connected by screws, and the connection between the corrugated telescopic tube and the blocking disc is continuous.

[0010] By adopting the above technical solution and using the corrugated telescopic tube structure, the received liquid medium can be transported through the blocking disc.

[0011] In a preferred embodiment, the upper container tank includes an upper container tank shell, a lower mounting flange ring, a top solenoid valve, and an electric cylinder mounting chassis. The lower mounting flange ring is fixed to the lower periphery of the upper container tank shell, and the electric cylinder mounting chassis is installed in the middle of the lower end of the upper container tank shell. The top solenoid valve is installed on the outer side of the electric cylinder mounting chassis on the upper container tank. The top solenoid valve is mounted and connected to the corrugated telescopic pipe, and the electric cylinder mounting chassis is mounted and connected to the first electric telescopic cylinder.

[0012] By adopting the above technical solution, the upper container tank structure can receive the liquid medium and isolate the transport pressure of the liquid pipeline.

[0013] In a preferred embodiment, the lower container includes a graduated observation window, a lower container shell, and an upper mounting flange ring. The upper mounting flange ring is fixedly connected to the upper circumference of the lower container shell, and a graduated observation window is installed in the middle of the front end of the upper mounting flange ring. The lower container shell is mounted on the sampling valve cover.

[0014] By adopting the above technical solution, liquid media can be collected through the lower container tank structure.

[0015] In a preferred embodiment, the sampling valve cover includes a cover shell, a bottom sleeve, an intermediate delivery pipe, and a first solenoid valve. The bottom sleeve is fixedly connected to the lower middle of the cover shell. An intermediate delivery pipe is fixedly connected to the interior of the cover shell and the bottom sleeve. The first solenoid valve is installed at the upper end of the intermediate delivery pipe. The first solenoid valve is installed and connected to the liquid phase pipeline. The bottom sleeve is installed and connected to the upper container tank through the cover shell.

[0016] By adopting the above technical solution and using the sampling valve cover structure, it is possible to seal and transport liquid media.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0018] 1. In this application, the sampling control mechanism can adjust the sampling capacity by raising and lowering the sample. When the first electric telescopic cylinder of the sampling control mechanism extends and retracts, it can change the position of the blocking disc. The blocking disc is fitted inside the lower container, thereby changing the sampling collection capacity inside the lower container. A corrugated telescopic tube is installed at the upper end of the blocking disc. The extension and retraction of the corrugated telescopic tube during the raising and lowering of the blocking disc prevents obstruction. The first electric telescopic cylinder and the corrugated telescopic tube are installed and connected to the upper container, allowing for corresponding installation and placement.

[0019] 2. In this application, the sampling valve cover is closed, so that the pressure in the upper container tank is not as high as the internal pressure of the liquid phase pipeline, thus facilitating personnel sampling. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Example 1

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a liquid phase sampling device includes a liquid phase pipeline 1 and a sampling valve cover 2. The sampling valve cover 2 is installed and connected to the outer end of the liquid phase pipeline 1. When the sampling valve cover 2 opens its internal flow channel, the liquid phase substance inside the liquid phase pipeline 1 is transported through the sampling valve cover 2. An upper container tank 3 is fixedly connected to the lower end of the sampling valve cover 2, and the sampling valve cover 2 transports the liquid phase medium into the upper container tank 3. Then, the sampling valve cover 2 closes, so that the pressure in the upper container tank 3 is not as high as the pressure inside the liquid phase pipeline 1, thereby facilitating sampling by personnel. A sampling control mechanism is installed in the middle of the lower end of the upper container tank 3. 6. The sampling control mechanism 6 can receive the upper container tank 3. The lower container tank 4 is installed on the periphery of the sampling control mechanism 6 on the upper container tank 3. The sampling control mechanism 6 can sample the contents of the lower container tank 4. A bottom solenoid valve 5 is installed at the lower end of the lower container tank 4. The sampled liquid medium in the lower container tank 4 can be discharged and collected through the bottom solenoid valve 5. The sampling valve cover 2, the upper container tank 3, the bottom solenoid valve 5 and the sampling control mechanism 6 are electrically connected to the external central processing panel box through the connecting wire. In this way, they can be operated and controlled through the external central processing panel.

[0028] The sampling control mechanism 6 includes a first electric telescopic cylinder 61, a corrugated telescopic tube 62, and a blocking disc 63. The lower end of the telescopic rod of the first electric telescopic cylinder 61 is equipped with the blocking disc 63. When the telescopic rod of the first electric telescopic cylinder 61 extends or retracts, it can change the position of the blocking disc 63. The blocking disc 63 is sleeved inside the lower container tank 4, thereby changing the sampling collection capacity inside the lower container tank 4. The upper end of the blocking disc 63 is equipped with the corrugated telescopic tube 62. When the blocking disc 63 is raised or lowered, the extension and retraction state of the corrugated telescopic tube 62 ensures that there is no obstruction during the raising and lowering of the container tank 3. The first electric telescopic cylinder 61 and the corrugated telescopic tube 62 are installed and connected to the upper container tank 3, so that they can be installed and placed accordingly.

[0029] The corrugated expansion tube 62 and the blocking disc 63 are connected by screws, which facilitates installation and disassembly by personnel. The connection between the corrugated expansion tube 62 and the blocking disc 63 is open, so that the liquid medium can be transported accordingly without obstruction during transport.

[0030] The upper container tank 3 includes an upper container tank shell 31, a lower mounting flange ring 32, a top solenoid valve 33, and an electric cylinder mounting base 34. The lower mounting flange ring 32 is fixedly connected to the lower circumference of the upper container tank shell 31. The lower mounting flange ring 32 is connected to the lower container tank 4 by screws, allowing for corresponding installation. The electric cylinder mounting base 34 is installed in the middle of the lower end of the upper container tank shell 31. The electric cylinder mounting base 34 is mounted on the first electric telescopic cylinder 61, which can then be correspondingly... The electric cylinder mounting chassis 34 is equipped with a top solenoid valve 33 on the outside of the upper container tank 3. When the internal flow channel of the top solenoid valve 33 is open, the liquid medium inside the upper container tank 3 can be discharged and transported through the top solenoid valve 33. The top solenoid valve 33 is installed and connected to the corrugated expansion pipe 62. The liquid medium discharged by the top solenoid valve 33 can be transported into the corrugated expansion pipe 62, and then transported to the collection chamber inside the lower container tank 4 below the blocking disc 63 through the corrugated expansion pipe 62.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, the lower container 4 includes a graduated observation window 41, a lower container shell 42, and an upper mounting flange ring 43. The upper mounting flange ring 43 is fixedly connected to the upper circumference of the lower container shell 42. The upper mounting flange ring 43 is connected to the sampling valve cover 2 by screws, which facilitates corresponding installation and placement. The lower container shell 42 is hollow inside, so that liquid media can be stored for sampling. A graduated observation window 41 is installed in the middle of the front end of the lower container shell 42. The scale of the graduated observation window 41 makes it easy for personnel to check the internal sampling capacity of the lower container shell 42.

[0032] The sampling valve cover 2 includes a cover shell 21, a bottom sleeve 22, an intermediate delivery pipe 23, and a first solenoid valve 24. The bottom sleeve 22 is fixedly connected to the lower middle of the cover shell 21. The bottom sleeve 22 is installed and connected to the upper container tank 3 by screws on the cover shell 21, so that they can be installed and placed accordingly. The intermediate delivery pipe 23 is fixedly connected to the middle of the cover shell 21 and the bottom sleeve 22. The liquid phase medium received by the intermediate delivery pipe 23 can be delivered to the upper container tank 3. The first solenoid valve 24 is installed at the upper end of the intermediate delivery pipe 23. The first solenoid valve 24 is installed and connected to the liquid phase pipeline 1. When the internal flow channel of the first solenoid valve 24 is opened, the liquid phase medium inside the liquid phase pipeline 1 can be delivered to the intermediate delivery pipe 23 through the first solenoid valve 24.

[0033] The implementation principle of the liquid phase sampling device embodiment of this application is as follows: In use, the sampling valve cover 2 is installed and connected to the outer end of the liquid phase pipeline 1. When the sampling valve cover 2 opens the internal flow channel, the liquid phase substance inside the liquid phase pipeline 1 is transported through the sampling valve cover 2, and the sampling valve cover 2 transports the liquid phase medium to the upper container tank 3. Then the sampling valve cover 2 is closed, so that the pressure of the upper container tank 3 is not as high as the internal pressure of the liquid phase pipeline 1, thereby facilitating personnel sampling. The sampling control mechanism 6 is located on the periphery of the upper container tank 3 and a lower container tank 4 is installed. The sampling control mechanism 6 can sample the capacity inside the lower container tank 4. A bottom solenoid valve 5 is installed at the lower end of the lower container tank 4. The sampled liquid phase medium in the lower container tank 4 can be discharged and collected through the bottom solenoid valve 5.
