[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] See also Figure 1-3, the utility model provides an embodiment: a liquid level gauge with a sampling function, including a liquid level tube 1, the lower end of the liquid level tube 1 is fixedly connected to a tee tube 6, and a first valve 7 is installed at the connection between the tee tube 6 and the liquid level tube 1, and the other two ports of the tee tube 6 are respectively fixedly connected to a sampling tube 10 and a second valve 8. A threaded hole is provided at the middle position of the lower end surface of the sampling tube 10, and a screw 11 is connected to the inner thread of the threaded hole. A piston block 9 is rotatably installed at one end of the screw 11. The piston block 9 is located inside the sampling tube 10, and a scale groove 13 is provided on the side surface of the screw 11. A hand wheel 12 is fixedly connected to one end of the screw 11. When sampling is needed, the first valve 7 can be opened to connect the sampling tube 10 with the inside of the liquid level tube 1, and then the screw 11 is rotated. Due to the screw 11 and the sampling tube 10 One end is threadedly connected, so the rotation of the screw 11 can move the axial position, thereby causing the piston block 9 to move inside the sampling tube 10. At this time, the solution inside the liquid level tube 1 can be effectively extracted. Since a scale groove 13 is provided on the outer surface of the screw 11, the position of the piston block 9 can be accurately adjusted, thereby accurately controlling the amount of solution extracted from the sampling tube 10. After the extraction is completed, the first valve 7 is closed, and then the second valve 8 is opened, and then the screw 11 is rotated in the opposite direction to move the piston block 9 to the reverse position inside the sampling tube 10, thereby squeezing out the solution inside the sampling tube 10 to achieve a complete sampling operation. During the entire sampling process, a segmented control method is adopted to avoid directly extracting the solution from the high-pressure liquid level tube 1, which can effectively avoid accidents, and the safety and practicality are effectively improved.

[0019] Furthermore, a float 14 is provided inside the liquid level tube 1, a snap groove is provided on the side surface of the float 14, and a plurality of permanent magnets 15 are snap-fitted inside the snap groove. A display box 4 is fixedly installed on the side surface of the liquid level tube 1, a cavity is provided inside the display box 4, and liquid metal is provided inside the cavity. The upper and lower ends of the side surface of the liquid level tube 1 are respectively integrally connected with a first liquid guide tube 2 and a second liquid guide tube 3. A cover plate 5 is installed at the upper port of the liquid level tube 1, wherein the second liquid guide tube 3 can be used to introduce the solution in the external container into the interior of the liquid level tube 1. At this time, the float 14 floats on the surface of the solution, and the permanent magnet 15 snapped on the float 14 can attract the liquid metal inside the display box 4 and place part of the liquid metal at the same level as the liquid level, which can facilitate the staff to quickly check the liquid level height inside the container.

[0020] Working principle: When in use, first install the liquid level gauge at the designated position, then use the second liquid guide tube 3 to guide the solution in the external container into the interior of the liquid level tube 1, and the float 14 floats on the surface of the solution. The permanent magnet 15 clipped on the float 14 can attract the liquid metal inside the display box 4 and place part of the liquid metal at the same level as the liquid level, which can facilitate the staff to quickly check the liquid level height inside the container. During use, when it is necessary to sample the solution inside the container, open the first valve 7 to connect the sampling tube 10 with the interior of the liquid level tube 1, and then turn the screw 11. Since the screw 11 is threadedly connected to one end of the sampling tube 10, the rotation of the screw 11 can The axial position is moved, and the piston block 9 is moved inside the sampling tube 10. At this time, the solution inside the liquid level tube 1 can be effectively extracted. Since a scale groove 13 is provided on the outer surface of the screw 11, the position of the piston block 9 can be accurately adjusted, and the amount of solution extracted by the sampling tube 10 can be accurately controlled. After the extraction is completed, the first valve 7 is closed, and then the second valve 8 is opened, and then the screw 11 is rotated in the opposite direction to move the piston block 9 to the reverse position inside the sampling tube 10, and then the solution inside the sampling tube 10 is squeezed out to achieve a complete sampling operation. In the entire sampling process, a segmented control method is adopted to avoid directly extracting the solution from the high-pressure liquid level tube 1, which can effectively avoid accidents.
