Example Embodiment

[0035] The invention is like Figure 1-2 As shown, an interlayer 2 is provided on the outer side wall of the tank body 1, an auxiliary pipe 3 is connected to the interlayer, a plug 4 is provided in the auxiliary pipe, and a sealing ring 5 is provided on the plug;

[0036] It also includes valve body one 6, valve body two 7, vacuum ball valve one 8, vacuum ball valve two 9 and valve stem 10. Both ends of the valve body one are provided with openings, and one end of the valve body one is detachable from the auxiliary pipe Connect, the other end is fixedly connected with the vacuum ball valve;

[0037] The valve body two has an opening at one end facing the vacuum ball valve one, the vacuum ball valve one and the valve body two are connected by a clamp one 11, and the valve stem is connected to the end of the valve body two away from the vacuum ball valve one. The valve stem is movably connected in valve body two, vacuum ball valve one and valve body one;

[0038] The valve stem and the plug are detachably connected;

[0039] An interface 12 is provided on the outer side of the second valve body, and the interface is connected to the second vacuum ball valve through a clamp two 13, and the second vacuum ball valve is connected to a vacuum pump.

[0040] In the work of the present invention, a vacuum ball valve 1 is arranged between the valve body 1 and the valve body 2, wherein the valve body 1 and the vacuum ball valve 1 are fixedly connected, the valve body 2 and the vacuum ball valve 1 are connected by a clamp 1; the valve body 2 A vacuum ball valve 2 is set between the interface and the vacuum pump;

[0041] For specific replacement, proceed as follows: the interlayer is kept in a vacuum state, and the plug is located in the auxiliary pipe; the vacuum ball valve one and two are opened, and the vacuum pump vacuums the valve body one and the valve body two; the vacuum ball valve two is closed; the plug is closed through the valve stem Pull into the valve body two; close the vacuum ball valve; open the clamp, separate the valve body two and the vacuum ball valve one; replace the plug or sealing ring; once the clamp is closed, assemble the valve body two and the vacuum ball valve one ; The second vacuum ball valve is opened, and the vacuum pump will vacuum the second valve body; the second vacuum ball valve is closed; the first vacuum ball valve is opened; the plug is pushed into the auxiliary pipe through the valve stem; the sealing is completed.

[0042] It also includes a lock nut 14. The lock nut is provided with an inner retainer ring 15, the valve body is provided with an outer retainer ring 16 at one end facing the auxiliary pipe, and the lock nut is sleeved on the valve body, so The inner retaining ring is in contact with the outer retaining ring;

[0043] The auxiliary pipe is provided with an external thread, and the lock nut and the auxiliary pipe are connected by threads.

[0044] The inner retaining ring of the lock nut is in contact with the outer retaining ring of the auxiliary pipe, and the lock nut is threaded to the auxiliary pipe, thereby driving the valve body to move to the auxiliary pipe until the two contact, which is convenient for disassembly and assembly and reliable operation.

[0045] A sealing ring (that is, an annular sealing ring 18) is arranged between the end surface of the auxiliary pipe and the end surface of the valve body one.

[0046] In this way, the sealing performance between the auxiliary pipe and the valve body 1 is improved, which facilitates subsequent vacuuming and improves reliability.

[0047] The plug is provided with an internal threaded hole, the end of the valve stem is provided with an external thread, and the plug and the valve stem are connected by threads.

[0048] The two are connected by thread, which is convenient for disassembly and assembly and reliable operation.

[0049] A vacuum gauge 17 is provided on the interlayer. By setting a vacuum gauge, it is convenient to measure the vacuum degree in the interlayer.

[0050] A working method of a plug replacement device for tank vacuum, including the following steps:

[0051] S1: The interlayer is kept in a vacuum state, and the plug is located in the auxiliary pipe; the vacuum ball valve one and two are opened, and the vacuum pump vacuumizes the valve body one and the valve body two;

[0052] S2: Vacuum ball valve two is closed;

[0053] S3: Pull the plug into the second valve body through the valve stem;

[0054] S4: Once the vacuum ball valve is closed;

[0055] S5: Once the clamp is opened, separate the valve body 2 and the vacuum ball valve 1;

[0056] S6: Replace the plug or sealing ring;

[0057] S7: As soon as the clamp is closed, assemble the valve body 2 and the vacuum ball valve 1;

[0058] S8: The second vacuum ball valve is opened, and the second valve body is evacuated by the vacuum pump;

[0059] S9: The second vacuum ball valve is closed;

[0060] S10: As soon as the vacuum ball valve is opened;

[0061] S11: Push the plug into the auxiliary pipe through the valve stem;

[0062] S12: Complete.

[0063] The invention realizes the communication between the valve body one and the valve body two by controlling the switch of the vacuum ball valve one, which is convenient for vacuuming the valve body one and the valve body two; at the same time, it is convenient for the valve stem to drive the plug to move;

[0064] By controlling the switch of the vacuum ball valve two, it is convenient for the vacuum pump to perform the vacuuming action and convenient for operation.
