Most of the existing liquid level gauges are flat-panel liquid level gauges fixedly installed on one side of the storage tank, which is not convenient for users to observe from multiple directions. At the same time, the outer casing of the liquid level gauge installed naked is mostly made of glass material, and it is easily damaged by collision during actual use. Therefore, in view of this, the existing structure and deficiencies are studied and improved to provide a hydrogen peroxide storage tank liquid level gauge, with the aim of achieving a more practical value.

[0026] Among them, the connector includes a threaded seat 4 and a fixed pipe 5. The inner side of the threaded seat 4 is rotationally connected to the outer side of the fixed pipe 5. Threads that can be threadedly connected to the threaded seat 4 are provided on the outer sides of both ends of the protective housing 2. The structure is simple and it is convenient to connect the protective housing 2 and the fixed pipe 5.

[0027] Among them, a limiting ring 6 is fixedly installed at one end of the fixed pipe 5 close to the protective housing 2. A reduced opening that is limited to the limiting ring 6 is provided at one end of the threaded seat 4, and the inner diameter of the reduced opening is equal to the outer diameter of the fixed pipe 5, preventing the threaded seat 4 from moving excessively when connecting the protective housing 2 and disengaging from the fixed pipe 5.

[0028] Wherein, sealing sleeves 7 are installed on the inner sides of both ends of the protective housing 2. One end of the sealing sleeve 7 abuts and connects with one end of the liquid level gauge body 1. The outer side of the sealing sleeve 7 fits with the inner side of the liquid level gauge body 1, and sealant is filled at the connection between the sealing sleeve 7 and the liquid level gauge body 1 to prevent hydrogen peroxide from leaking out from the connection between the sealing sleeve 7 and the liquid level gauge body 1.

[0029] Wherein, the sealing sleeve 7 abuts against the limiting ring 6 on the side away from the liquid level gauge body 1 to prevent hydrogen peroxide from leaking out from the connection between the sealing sleeve 7 and the limiting ring 6.

[0030] Wherein, one end of the fixed pipe 5 is connected through a communicating pipe 8. One end of the communicating pipe 8 is connected through a flange 9 with a connecting pipe 10, and the connecting pipe 10 is connected with the storage tank, facilitating the liquid level gauge body 1 to obtain hydrogen peroxide from the storage tank, and then quickly detecting the liquid level height in the tank.

[0031] Wherein, a control valve 11 is installed on one end of the communicating pipe 8. When it is necessary to disassemble and install the protective housing 2 and the liquid level gauge body 1, the connection between the communicating pipe 8 and the connecting pipe 10 can be closed to prevent hydrogen peroxide from flowing out of the communicating pipe 8 when disassembling and installing the protective housing 2 and the liquid level gauge body 1.

[0032] Wherein, scale lines are engraved on one side of the protective housing 2 to facilitate users to quickly observe the data of the liquid level gauge body 1.

[0033] The working principle of this embodiment: When it is necessary to install the liquid level gauge body 1, first, the protective housing 2 is sleeved on the outer side of the liquid level gauge body 1. The sealing sleeve 7 is installed on the inner side of the liquid level gauge body 1 and sealant is filled. The two ends of the protective housing 2 are respectively placed inside the upper and lower groups of threaded seats 4. Rotating the bottom threaded seat 4 drives the protective housing 2. When the protective housing 2 moves, it drives the sealing sleeve 7 to abut against the limiting ring 6. Rotating the top threaded seat 4 fixes the protective housing 2, and the installation of the liquid level gauge body 1 is completed.

[0034] Finally, it should be noted that the liquid level gauge body 1 is a device or equipment existing in the prior art, specifically a transparent glass tube.
