A buckle is provided between the end cover 1 and the barrel cover body 2, and the end cover 1 and the barrel cover body 2 are buckled through the buckle. Two ventilation holes 3 are provided on the outer wall of the barrel cover body 2, and ventilation valves are installed in the two ventilation holes 3. The main function of the ventilation valve is to adjust and control the pressure and gas flow in the container to prevent the formation of vacuum or overpressure inside the container, thereby protecting the safety and efficiency of the container. And the flow channel of the ventilation valve is one-way, and methanol liquid cannot flow out.

[0024] A threaded groove is provided on the outer wall of the barrel cover body 2, and a plug fixing ring 5 is threadedly connected to the inner wall of the threaded groove. An annular groove is provided at the top of the plug fixing ring 5, and a first sealing gasket 4 is placed on the inner wall of the annular groove. The first sealing gasket 4 increases the sealing performance between the liquid outlet cover 13 and the plug fixing ring 5.

[0025] A second sealing gasket 6 is fixedly connected to the top inner wall of the plug fixing ring 5. When liquid extraction is not required, the second sealing gasket 6 blocks the liquid outlet position at the top of the plug fixing ring 5 to play a sealing role. A third sealing gasket 8 is fixedly connected to the inner wall of the bottom of the barrel cover body 2, and the third sealing gasket 8 seals the barrel cover body 2 after being threadedly connected to the barrel container.

[0026] The outer wall of the plug fixing ring 5 is provided with a liquid outlet mechanism. The liquid outlet mechanism includes a plug 7. The inner wall of the plug fixing ring 5 is slidably connected to the outer wall of the plug 7. A spring 9 is sleeved at the bottom of the plug 7. The bottom of the spring 9 is in contact with the outer wall of the barrel cover body 2. The spring 9 drives the plug 7 to move upward through its own elastic force.

[0027] A fourth sealing gasket 10 is provided between the bottom of the plug fixing ring 5 and the outer wall of the barrel cover body 2. The fourth sealing gasket 10 increases the sealing performance between the bottom of the plug fixing ring 5 and the barrel cover body 2 to avoid liquid leakage during liquid extraction. An inlet 11 is provided at the bottom of the barrel cover body 2. A pipe can be sleeved on the outer wall of the inlet 11. The bottom of the pipe extends into the interior of the barreled container. The outer wall of the plug fixing ring 5 is threadedly sleeved with a liquid outlet cover 13. The bottom of the liquid outlet cover 13 presses against the top of the plug 7. A notch is provided at the bottom of the liquid outlet cover 13. A plurality of flow channels are provided on the outer wall of the plug 7.

[0028] The methanol solution flows into the plug fixing ring 5 through the inlet 11, passes through the plurality of flow channels on the plug 7, flows from the notch at the bottom of the liquid outlet cover 13 to the liquid outlet 12, generates a negative pressure suction through an existing pump body, and the liquid outlet 12 is docked with the input end of the pump body to extract the methanol liquid. The bottom of the liquid outlet cover 13 presses against the top of the first sealing gasket 4. A liquid outlet 12 is provided at the top of the liquid outlet cover 13.

[0029] Working principle: When in use, threadedly dock the inner thread at the bottom of the barrel cover body 2 with the barreled container, and then install two existing ventilation valves on the two ventilation holes 3 respectively.

The bottom of the liquid outlet cover 13 no longer presses against the top of the plug 7. The plug 7 moves upward under the action of the spring 9. After the plug 7 moves upward, the top of the plug 7 is tightly fitted together through the second sealing gasket 6 to block the liquid outlet position at the top of the plug fixing ring 5, playing a sealing role. Then cover the end cover 1 of the barrel cover to seal the methanol liquid in the barrel; when liquid needs to be taken, screw the liquid outlet cover 13 onto the plug fixing ring 5 to increase the sealing performance through the first sealing gasket 4. At this time, the top of the plug 7 is pressed and will move downward, and the spring 9 is compressed by force, and the liquid channel is opened. The methanol solution flows into the plug fixing ring 5 through the inlet 11, passes through the plurality of flow channels on the plug 7, and flows from the notch at the bottom of the liquid outlet cover 13 to the liquid outlet 12 to extract the liquid.
