[0026] The current liquid level gauge sealing device is formed by combining multiple layers of sealing rings, and the multiple layers of sealing rings are movably superimposed. If the measured liquid is a high-temperature, high-pressure or corrosive liquid, the sealing ring is a consumable and is prone to surface corrosion and wear over a long period of use, resulting in gaps between adjacent sealing rings, thereby affecting the sealing effect of the liquid level gauge.

[0027] See also Figure 1-Figure 5 As shown, the device includes a base body 1, which is composed of a top cover 11 and a bottom box 12. A threaded ring 13 is fixedly connected to the surface of the top cover 11, and a mounting groove 14 that fits the surface of the threaded ring 13 is provided on the surface of the bottom box 12. A liquid level meter body 16 is stored inside the bottom box 12, and a liquid inlet hole 15 is provided at the bottom of the bottom box 12. A sealing component 2 is connected to the inner cavity of the bottom box 12, and a mounting component 3 for improving the installation stability of the sealing component 2 is installed on the outer wall of the sealing component 2.

[0028] First, the specific structure of the sealing component 2 is disclosed. The sealing component 2 includes an inner pad 21 arranged inside the bottom box 12. The outer wall of the inner pad 21 is fixedly connected with a middle pad 22. The outer wall of the middle pad 22 is installed with an outer pad 23. The inner wall of the inner pad 21 fits with the surface of the liquid level meter body 16. The surface of the outer pad 23 fits with the inner wall of the bottom box 12. The middle pad 22 is a hollow bag structure. A connecting pipe 24 is installed on the top of the middle pad 22. The middle pad 22 is arranged between the outer pad 23 and the inner pad 21, and the middle pad 22 is made of a hollow bag material. When the inner pad 21 is sleeved on the surface of the liquid level meter body 16, gas is transported to the middle pad 22 through the connecting pipe 24, so that the outer pad 23 can fit with the inner wall of the bottom box 12, so as to achieve the effect of sealing the liquid level meter body 16. Among them, the inner pad 21, the middle pad 22 and the outer pad 23 are an integrated structure, which further improves the sealing effect of the liquid level meter body 16.

[0029] Next, the specific structure of the installation component 3 is disclosed. The installation component 3 includes a limiting groove 32 opened on the inner wall of the bottom box 12. The outer wall of the outer pad 23 is fixedly connected to the limiting block 31, and the surface of the limiting block 31 is in contact with the inner wall of the limiting groove 32. When the gas is transported to the center pad 22, the center pad 22 expands and drives the outer pad 23 to stretch, so that the limiting block 31 connected to the surface of the outer pad 23 is clamped in the inner part of the limiting groove 32, which effectively reduces the situation where the sealing component 2 moves on the surface of the liquid level meter body 16, thereby improving the sealing effect of the liquid level meter body 16.

[0030] The improvement of this embodiment is that: first, by means of the threaded ring 13 provided on the top of the top cover 11 and the mounting groove 14 provided on the surface of the bottom box 12, the top cover 11 and the bottom box 12 can be threadedly mounted to form a base body 1, which is convenient for mounting the liquid level gauge body 16. When the inner pad 21 is sleeved on the surface of the liquid level gauge body 16, gas is transported to the middle pad 22 through the connecting pipe 24, so that the outer pad 23 can fit with the inner wall of the bottom box 12, thereby achieving the effect of sealing the liquid level gauge body 16. The inner pad 21, the middle pad 22 and the outer pad 23 are an integrated structure, which further improves the sealing effect of the liquid level gauge body 16.

[0031] When gas is transported to the center pad 22, the center pad 22 expands and drives the outer pad 23 to stretch, so that the limit block 31 connected to the surface of the outer pad 23 is clamped in the inside of the limit groove 32, effectively reducing the movement of the sealing assembly 2 on the surface of the liquid level meter body 16, thereby improving the sealing effect of the liquid level meter body 16.

[0032] Considering the service life of the sealing component 2 as a whole, in order to further improve the service life of the sealing component 2 as a whole and reduce the corrosion of its surface, Figure 5 As shown, the surfaces of the inner pad 21 and the outer pad 23 are both paved with anti-corrosion pavement 4 .

[0033] The improvement lies in that the anti-corrosion pavement 4 laid on the surface of the inner pad 21 and the outer pad 23 can increase the overall service life of the sealing component 2, reduce the corrosion of the surface of the sealing component 2, and then improve the sealing effect of the liquid level meter body 16, wherein the anti-corrosion pavement 4 can be made of silicone rubber coating, fluororubber coating or acrylic coating material.

[0034] Since the top cover 11 and the bottom box 12 need to be threadedly connected, and the connecting pipe 24 extends out of the surface of the middle cushion 22, in order to facilitate the storage of the connecting pipe 24, the connecting pipe 24 is preferably placed in a storage container 10. Figure 1-Figure 4 As shown, the connecting pipe 24 is a foldable structure as a whole.

[0035] The improvement lies in that: the connecting tube 24 is a foldable structure. When the base body 1 needs to be closed, the connecting tube 24 can be folded to reduce the size of the connecting tube 24 extending out of the surface of the middle pad 22, which is convenient for storing the connecting tube 24 without affecting the closing of the base body 1. The connecting tube 24 can be made of a corrugated tube material.

[0036] In summary, the working principle of this solution is as follows: first, by setting the threaded ring 13 on the top of the top cover 11 and the installation groove 14 opened on the surface of the bottom box 12, the top cover 11 and the bottom box 12 can be threadedly installed to form a base body 1, which is convenient for installing the liquid level gauge body 16. When the inner pad 21 is sleeved on the surface of the liquid level gauge body 16, the gas is transported to the middle pad 22 through the connecting pipe 24, so that the outer pad 23 can fit with the inner wall of the bottom box 12 to achieve the effect of sealing the liquid level gauge body 16, wherein the inner pad 21, the middle pad 22 and the outer pad 23 are an integrated structure, which further improves the sealing effect of the liquid level gauge body 16. The connecting pipe 24 is a foldable structure. When the base body 1 needs to be closed, the connecting pipe 24 can be folded to reduce the size of the connecting pipe 24 extending out of the surface of the middle pad 22, which is convenient for storing the connecting pipe 24 without affecting the closing of the base body 1, wherein the connecting pipe 24 can be made of a bellows material;

[0037] When gas is transported to the center pad 22, the center pad 22 expands and drives the outer pad 23 to stretch, so that the limit block 31 connected to the surface of the outer pad 23 is clamped in the inside of the limit groove 32, effectively reducing the movement of the sealing component 2 on the surface of the liquid level meter body 16, thereby improving the sealing effect of the liquid level meter body 16. The anti-corrosion pavement 4 laid on the surface of the inner pad 21 and the outer pad 23 can increase the overall service life of the sealing component 2, reduce the corrosion of the surface of the sealing component 2, and thereby improve the sealing effect of the liquid level meter body 16. The anti-corrosion pavement 4 can be made of silicone rubber coating, fluororubber coating or acrylic coating.
