[0002] After the installation of the crude benzene tank steel belt level gauge is completed, during the process of entering the medium crude benzene, the gas detection probe near the benzene tank always alarms, and the operator can always smell a strong smell of benzene when passing by during the inspection. After inspection, it is found that the smell is leaking from the steel belt sleeve, which poses a considerable safety hazard. During the installation process of the steel belt level gauge, the steel belt sleeve extends from the crude benzene tank to the ground dial, and cannot be sealed. In the prior art, the application with the publication number CN215261953U discloses an anti-volatile liquid level gauge, which includes a liquid seal pipe, a pulley is installed inside the liquid seal pipe, the steel belt is wound around the outside of the pulley, the two ends of the steel belt extend out of the liquid seal pipe, the middle part of the liquid seal pipe is provided with a liquid seal bending section, and one end of the liquid seal pipe is detachably provided with a mounting pipe. By using the liquid seal pipe, the volatile gas in the tank is prevented from volatilizing from the liquid level gauge hole, thereby avoiding pollution. However, its structure is relatively complicated, and it is troublesome to add the sealing liquid. At present, there is a lack of a simpler sealing structure. Utility Model Content

In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the creation of the present invention.

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] Embodiment 1: A sealing structure for a steel belt type liquid level gauge, such as Figure 1-Figure 3 As shown, it includes a tank body 1, on which a guide pipe Ⅰ3 is provided, and the guide pipe Ⅰ3 is connected to a connecting component Ⅰ, and the connecting component Ⅰ is connected to one side of the sealed oil pot 6 through a sealing pipe Ⅰ15, and the other side of the sealed oil pot 6 is connected to a connecting component Ⅱ through a sealing pipe Ⅱ16, and the connecting component Ⅱ is connected to a liquid level meter body through a guide pipe Ⅱ10; the connecting component Ⅰ and the connecting component Ⅱ both include an elbow 4, and a fixed pulley Ⅰ5 is provided inside the elbow 4; a fixed pulley Ⅱ is provided at the bottom of the sealed oil pot 6; the liquid level meter body is connected to one end of a steel belt, and the other end of the steel belt is connected to a float 11 after passing through the fixed pulley Ⅰ5 of the connecting component Ⅱ, the fixed pulley Ⅱ of the sealed oil pot 6 and the fixed pulley Ⅰ5 of the connecting component Ⅱ in sequence, and the float 11 is located inside the tank body 1; the sealing pipe Ⅰ15, the sealed oil pot 6, and the sealing pipe Ⅱ16 are connected in sequence to form a V-shaped structure to prevent the sealing oil of the sealed oil pot 6 from overflowing. The utility model ensures the sealing of the whole system and avoids the problem of benzene gas leakage by arranging the guide pipe and the connecting assembly and the connection mode of the sealing pipe and the sealing oil pot 6.

[0021] Embodiment 2: A sealing structure applied to a steel belt type liquid level gauge, wherein the sealing oil pot 6 is provided with two connecting holes 12, and the sealing oil pot 6 is connected to the sealing pipe Ⅰ15 and the sealing pipe Ⅱ16 through the two connecting holes 12 respectively; the connecting holes 12 are located below the two sides of the sealing oil pot 6; the sealing oil pot 6 is provided with an injection port 9 at the top, and the bottom of the sealing oil pot 6 is funnel-shaped, and a discharge port 13 is provided at the bottom of the funnel to facilitate the discharge of waste liquid. The injection port 9 at the top of the sealing oil pot 6 is convenient for filling the sealing oil, and the discharge port 13 at the bottom is convenient for discharge and cleaning and maintenance; the upper plane of the sealing oil pot 6 is lower than the lowest point of the connecting component Ⅰ or the connecting component Ⅱ. Avoid sealing oil from entering the tank body 1 and causing pollution; the guide tube Ⅱ10 is provided with a clamp, which is fixed to one end of the fixing rod 2, and the other end of the fixing rod 2 is fixed to the tank body 1. The combined use of the clamp and the fixing rod 2 ensures the stability of the guide tube II 10, reduces the displacement problem caused by vibration, and improves the measurement accuracy; the fixed pulley I 5 and the fixed pulley II both include a mounting seat 8, a rotating wheel 14 is rotatably connected to the mounting seat 8, and a groove 7 is provided on the rotating wheel 14.

When the liquid level in the tank body 1 changes, the float 11 rises and falls with the liquid level, and the steel belt connected to the float 11 moves accordingly. The displacement of the steel belt is converted into a signal that can be read by the liquid level meter body, thereby displaying the actual liquid level. The internal benzene gas will be blocked by the sealing oil in the sealing oil pot 6 to ensure that the liquid inside the tank body 1 will not contact the external environment; the sealing oil can be added through the injection port 9 at the top of the sealing oil pot 6 to maintain the necessary liquid level. If the sealing oil needs to be maintained or replaced, it can be operated through the discharge port 13 at the bottom of the sealing oil pot 6.
