[0026] Embodiment 1

[0027] As Figure 1 shown:

[0028] A split pressure vessel with a mechanical seal device includes a split pressure vessel body 1, a tank cover A 11 installed on the top of the split pressure vessel body 1, and a tank cover B 12 installed on the bottom of the split pressure vessel body 1.

[0029] In this embodiment: In the existing split pressure vessel with a mechanical seal device {Publication (Announcement) Number}: CN203297613, a split pressure vessel is disclosed. In this patent, the split pressure vessel body 1, the tank cover A11, and the tank cover B12 proposed in this application document are disclosed. The split pressure vessel body 1, the tank cover A11, and the tank cover B12 in this application document adopt the same technical means as those in this existing technology. These technical means will not be elaborated one by one here. Regarding the existing upper seal assembly 2 in this application, further improvements are made. For details, refer to the disclosed technology below; to solve the technical problems existing in this existing technology, as disclosed in the background technology above, "Although this design can directly connect the tank body and the tank cover, when the internal pressure of the pressure vessel is relatively high during the use of the existing device, the sealing performance of the split pressure vessel connected by flanges is relatively poor, and air leakage may occur, which is not convenient for people to use". In combination, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, an upper seal assembly 2 and a lower seal assembly 3 are added on this basis.

[0030] Furthermore:

[0031] As Figures 1 to 4 shown:

[0032] Combined with the above content: It also includes an upper seal assembly 2 arranged between the split pressure vessel body 1 and the tank cover A11; the upper seal assembly 2 includes an upper insertion shaft seal plug 26 fixedly connected to the top surface of the split pressure vessel body 1, a first sealing ring 25 installed on the surface of the upper insertion shaft seal plug 26, and an upper connecting member A24 threadedly connected to the surface of the upper insertion shaft seal plug 26.

[0033] In this embodiment: When the pressure inside the split pressure vessel body 1 increases, the first gasket 22 first plays a sealing role, and the upper connecting member A24, the first sealing ring 25, and the upper insertion shaft seal plug 26 below the first gasket 22 can further play a sealing role, thereby greatly enhancing the sealing effect between the split pressure vessel body 1 and the tank cover A11.

[0034] Even further:

[0035] In an alternative embodiment, a first retaining ring 23 is installed at the top end of the upper connecting member A24, a first gasket 22 is installed at the top end of the first retaining ring 23, the bottom end of the tank cover A11 is fixedly connected with an upper insertion shaft A21, and the upper insertion shaft A21 and the upper connecting member A24 are threadedly connected.

[0036] In this embodiment: The threaded connection setting of the upper insertion shaft A21 and the upper connecting member A24 can improve the sealing effect between the split pressure vessel body 1 and the tank cover A11.

[0037] Furthermore:

[0038] In an alternative embodiment, the upper insertion shaft A21 is matched with the structure of the first gasket 22.

[0039] In this embodiment: The setting of the first gasket 22 can strengthen the sealing between the upper insertion shaft A21 and the upper connecting member A24.

[0040] Furthermore:

[0041] In an alternative embodiment, it further includes a lower sealing assembly 3 arranged between the split pressure vessel body 1 and the tank cover B12; the lower sealing assembly 3 includes a lower insertion shaft A31 fixedly connected to the bottom end of the split pressure vessel body 1, a lower insertion shaft sealing plug 33 arranged at the bottom end of the lower insertion shaft A31, and a lower connecting member A34 threadedly connected inside the lower insertion shaft sealing plug 33, and the lower connecting member A34 is fixedly connected to the tank cover B12.

[0042] In this embodiment: When the pressure inside the split pressure vessel body 1 rises, due to the threaded connection between the lower connecting member A34 and the lower insertion shaft sealing plug 33, the sealing between the split pressure vessel body 1 and the tank cover B12 is ensured.

[0043] Furthermore:

[0044] In an alternative embodiment, a spring 32 is fixedly connected between the lower insertion shaft A31 and the lower insertion shaft sealing plug 33. An internal thread 35 is provided inside the lower insertion shaft sealing plug 33, and an external thread 36 is provided on the surface of the lower connecting member A34.

[0045] In this embodiment: The settings of the external thread 36 and the internal thread 35 can make the lower insertion shaft sealing plug 33 and the lower connecting member A34 be connected together more tightly.

[0046] It should be noted that: The function of the spring 32 can make the lower insertion shaft A31 and the lower insertion shaft sealing plug 33 fit tightly together, thereby ensuring the overall sealing of the device.

[0047] Furthermore:

[0048] In an alternative embodiment, a second sealing ring 37 is installed at the top end of the lower connecting member A34.

[0049] In this embodiment: The setting of the second sealing ring 37 can enhance the sealing effect between the split pressure vessel body 1 and the tank cover B12.

[0050] Working principle: When the pressure inside the split pressure vessel body 1 increases, the first gasket 22 acts as a seal first. The upper connecting piece A24, the first sealing ring 25 and the upper interpenetrating shaft sealing plug 26 below the first gasket 22 can further enhance the sealing effect, thus greatly enhancing the sealing effect between the split pressure vessel body 1 and the tank cover A11. Since the lower connecting piece A34 and the lower interpenetrating shaft sealing plug 33 are threadedly connected, the sealing performance between the split pressure vessel body 1 and the tank cover B12 is ensured. Under the sealing action of the second sealing ring 37, the sealing effect between the split pressure vessel body 1 and the tank cover B12 can be further improved. The function of the spring 32 can make the lower interpenetrating shaft A31 and the lower interpenetrating shaft sealing plug 33 fit tightly, thereby ensuring the overall sealing performance of the device.

[0051] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
