Description

Technical Field

[0001] This utility model relates to the field of emulsion storage tank sealing technology, and in particular to a sealing structure for emulsion storage tanks. Background Technology

[0002] The sealing technology of emulsion storage tanks is structure-based, including dynamic and static sealing requirements. In static sealing, flanges are used to seal the pipes on the emulsion storage tank. Gaskets are clamped after the flanges are connected to achieve a sealed and protective structure.

[0003] The existing static sealing structure for pipelines on emulsion storage tanks relies solely on flanges and gaskets for sealing. Under long-term pressure or high-temperature conditions, the gaskets are prone to creep or stress relaxation, leading to a decrease in preload and seal failure. Alternatively, drastic temperature fluctuations can cause localized separation of the sealing surfaces, creating leakage channels.

[0004] Therefore, in view of the existing sealing structure of emulsion storage tanks, the gasket changes under long-term pressure or high temperature, resulting in a decrease in preload and sealing failure. This utility model can form a sealing structure by means of flange and sealing gasket, and simultaneously perform liquid injection sealing according to the set annular liquid storage cavity. According to the properties of the liquid, the overall sealing effect is improved, and gas can be prevented from entering or escaping when the gasket seal fails. Utility Model Content

[0005] To overcome the common problem of gaskets in emulsion storage tanks changing under long-term pressure or high temperature, leading to reduced preload and seal failure.

[0006] The technical solution of this utility model is as follows: a sealing structure for an emulsion storage tank, including an emulsion storage tank tube body. A supporting flange is integrally provided at the top of the emulsion storage tank tube body, and an annular liquid storage cavity is formed on the top surface of the supporting flange. A positioning protrusion is integrally provided on the top surface of the supporting flange, located outside the annular liquid storage cavity. A fixing stud is fixedly installed inside the annular liquid storage cavity, extending beyond the annular liquid storage cavity and the top surface of the supporting flange. A connecting tube body is installed above the supporting flange, and a connecting flange is integrally provided at the bottom end of the connecting tube body. A combination hole is formed on the connecting flange, and the combination hole is connected through the fixing stud. A nut is threaded onto the top of the fixing stud, and a washer is installed between the nut and the combination hole, with the washer surrounding the outside of the fixing stud.

[0007] Preferably, the bottom surface of the connecting flange is provided with an annular sealing layer, and the annular sealing layer extends into the interior of the annular liquid storage cavity. A sealing gasket is installed between the connecting flange and the supporting flange, and a positioning groove is provided on the sealing gasket, and the positioning groove is connected to the positioning protrusion.

[0008] Preferably, the fixing studs are distributed at equal angles within the annular liquid storage cavity, and the height of the fixing studs is greater than the height of the annular liquid storage cavity, and the diameter of the fixing studs is smaller than the spacing between the curved surfaces of the annular liquid storage cavity.

[0009] Preferably, the annular sealing layer and the connecting flange are integrated into a single structure, and the curved surface on the annular sealing layer slides and fits against the curved surface on the annular liquid storage cavity. The height of the annular sealing layer is less than the height of the fixing stud plus the thickness of the sealing gasket, and the height of the annular sealing layer is greater than the thickness of the sealing gasket.

[0010] Preferably, the annular sealing layers surround each other to form a cavity, and the internal space of the cavity is interconnected with the internal space of the combined hole and the annular liquid storage cavity.

[0011] Preferably, the sealing gasket is pressed and fitted against the bottom surface of the connecting flange and the bottom surface of the supporting flange, and the inner diameter of the sealing gasket is larger than the outer diameter of the annular sealing layer, and the outer diameter of the sealing gasket is equal to the outer diameter of the connecting flange and the supporting flange.

[0012] Preferably, the sealing gasket has positioning grooves distributed at equal angles, and the positioning grooves are connected to the positioning protrusions by a snap-fit ​​connection. The top of the positioning protrusions is chamfered, and the height of the positioning protrusions is less than the thickness of the sealing gaskets.

[0013] The beneficial effects of this utility model are:

[0014] 1. The annular liquid storage cavity and positioning groove on the support flange can be engaged to facilitate the positioning of the installed sealing gasket, maintain the stability of the sealing gasket installation, and facilitate the subsequent clamping and sealing of the sealing gasket by the support flange and connecting flange, preventing the sealing gasket from shifting during installation.

[0015] 2. Based on the annular liquid storage cavity set on the support flange, liquid injection and sealing work can be carried out. At the same time, during subsequent assembly and fixing, the connecting flange can drive the annular sealing layer to extend into the annular liquid storage cavity, so that the bottom surface of the annular sealing layer moves below the liquid surface, improving the sealing effect and making assembly convenient.

[0016] 3. The internal space of the annular liquid storage chamber is interconnected with the combined hole through the cavity formed by the annular sealing layer, which facilitates the discharge of gas inside the annular liquid storage chamber through the combined hole during the assembly process, and also facilitates the entry of the annular sealing layer into the annular liquid storage chamber to raise the liquid level.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a sealing structure for an emulsion storage tank, including an emulsion storage tank body 1, a supporting flange 2 integrally provided at the top of the emulsion storage tank body 1, and an annular liquid storage cavity 3 opened on the top surface of the supporting flange 2, and a positioning protrusion 4 integrally provided on the top surface of the supporting flange 2, the positioning protrusion 4 being located outside the annular liquid storage cavity 3, a fixing stud 5 fixedly installed inside the annular liquid storage cavity 3, and the fixing stud 5 extending out of the annular liquid storage cavity 3 and the top surface of the supporting flange 2, a connecting pipe body 6 installed above the supporting flange 2, and a connecting flange 7 integrally provided at the bottom end of the connecting pipe body 6, a combination hole 8 opened on the connecting flange 7, and the combination hole 8 being connected through the fixing stud 5, a nut 12 being threadedly installed at the top of the fixing stud 5, and a washer 13 being installed between the nut 12 and the combination hole 8, and the washer 13 being surrounding the outside of the fixing stud 5.

[0025] The bottom surface of the connecting flange 7 is provided with an annular sealing layer 9, and the annular sealing layer 9 extends into the interior of the annular liquid storage cavity 3. A sealing gasket 10 is installed between the connecting flange 7 and the supporting flange 2, and a positioning groove 11 is provided on the sealing gasket 10. The positioning groove 11 is connected to the positioning protrusion 4, which facilitates the subsequent assembly and sealing of the connecting flange 7 and the supporting flange 2.

[0026] The fixing studs 5 are evenly distributed within the annular liquid storage cavity 3, and the height of the fixing studs 5 is greater than the height of the annular liquid storage cavity 3. Furthermore, the diameter of the fixing studs 5 is smaller than the spacing between the curved surfaces of the annular liquid storage cavity 3. Based on the distribution and diameter of the fixing studs 5, it is beneficial to assemble the annular sealing layer 9 subsequently.

[0027] The annular sealing layer 9 and the connecting flange 7 are integrated into one structure. The curved surface on the annular sealing layer 9 slides and fits against the curved surface on the annular liquid storage cavity 3. The height of the annular sealing layer 9 is less than the height of the fixing stud 5 plus the thickness of the sealing gasket 10, and the height of the annular sealing layer 9 is greater than the thickness of the sealing gasket 10. The connecting flange 7 can drive the annular sealing layer 9 to extend into the interior of the annular liquid storage cavity 3, thereby contacting the liquid filled inside the annular liquid storage cavity 3 to achieve sealing.

[0028] The annular sealing layers 9 surround each other to form a cavity, and the internal space of the cavity is interconnected with the internal space of the combination hole 8 and the annular liquid storage cavity 3, which facilitates the air inside the annular liquid storage cavity 3 to be discharged through the cavity and the combination hole 8, thus facilitating the combined sealing operation.

[0029] The sealing gasket 10 is pressed and fitted against the bottom surface of the connecting flange 7 and the bottom surface of the supporting flange 2. The inner diameter of the sealing gasket 10 is larger than the outer diameter of the annular sealing layer 9, and the outer diameter of the sealing gasket 10 is equal to the outer diameter of the connecting flange 7 and the supporting flange 2. This allows the sealing gasket 10 to be installed on the outside of the annular sealing layer 9, thereby achieving a sealing combination.

[0030] The sealing gasket 10 has positioning grooves 11 distributed at equal angles, and the positioning grooves 11 are connected to the positioning protrusions 4 by a snap-fit ​​connection. The top of the positioning protrusions 4 is chamfered, and the height of the positioning protrusions 4 is less than the thickness of the sealing gasket 10. The sealing gasket 10 can be combined with the positioning protrusions 4 through the positioning grooves 11 to restrict the installation position of the sealing gasket 10, which facilitates subsequent clamping and fastening work.

[0031] Working principle: According to Figure 1 and Figures 4-5 First, liquid can be injected into the annular liquid storage cavity 3 so that the liquid level is at half the height of the annular liquid storage cavity 3. Then, the sealing gasket 10 is installed. The positioning groove 11 on the sealing gasket 10 engages with the positioning protrusion 4 to keep the sealing gasket 10 stable after installation.

[0032] according to Figures 1-4Then, the connecting pipe body 6 can drive the connecting flange 7 and the supporting flange 2 to work together. The combination hole 8 on the connecting flange 7 is connected to the fixing stud 5 through, so that the bottom surface of the connecting flange 7 is pressed and adhered to the top surface of the sealing gasket 10. At the same time, the connecting flange 7 drives the annular sealing layer 9 to extend into the annular liquid storage cavity 3, so that the bottom surface of the annular sealing layer 9 is lower than the liquid level inside the annular liquid storage cavity 3. During the installation process, the air inside the annular liquid storage cavity 3 and the annular sealing layer 9 is discharged through the combination hole 8. Finally, the gasket 13 is put on the outside of the fixing stud 5, so that the gasket 13 slides down to the top surface of the connecting flange 7. Then, the nut 12 is threaded onto the top of the fixing stud 5 and rotated down to fix the installation. The area is sealed by the installation and fixing of the gasket 13. Because the diameter of the gasket 13 is small, and the compression of the nut 12 reduces the phenomenon of leakage caused by temperature changes in the gasket 13.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
