[0034] Working principle: When the device is not installed, the plug 9 blocks the oil hole 23 under the action of the two push blocks 7. When using the device, press the button 3, and the push block 7 releases the sliding sleeve 11. As the sliding sleeve 11 slides and falls on the sliding shaft 10, the pressure rod 8 and the spring 6 are pushed open, and the sliding shaft 10 drives the plug 9 to fall, connecting the upper flange ring 4 and the lower flange ring 29. The plug 9 drives the pressure block 12 to press the push rod 30, and the air valve 27 is opened. At this time, the ball valve is operated. When it is not working, the wrench 5 is in a horizontal position. When the wrench 5 is in the set state, the wrench 5 drives the upper valve stem 13 and the lower valve stem 15 to rotate the ball core 14. The valve core 25 in the ball core 14 is the channel for gasoline. When the wrench 5 is horizontal, the valve core 25 faces the inner wall of the device and gasoline cannot pass through. When working, pull the wrench 5 up or down, the wrench 5 drives the upper valve stem 13 and the lower valve stem 15 to rotate, and the ball core 14 drives the valve core 25 to rotate. The valve core 25 aligns with the oil hole 23 and gasoline can pass through. When the device is working, open the ball valve and the plug 9 to work normally. After the bundle is tied, first turn the wrench 5 to drive the upper valve stem 13 and the lower valve stem 15 to rotate, and at the same time drive the ball core 14 and the valve core 25 to close the valve core 25 to prevent the gasoline from flowing downward. Press the button 3 to turn the device upside down, and the plug 9 slides to the top of the device. After releasing the button 3, the push block 7 again blocks the plug 9 to prevent it from falling, and the air valve 27 stops working. Among them, the sealing ring 22 in the ball valve is made of rubber sealing ring 22, which is resistant to dirt and has strong sealing to prevent gasoline from leaking out. The compression ring 22 set on one side of the upper valve stem 13 The sleeve 21 is used to compress the packing 20, and the bottom gasket 19 is also used to fix the packing 20 to prevent gasoline from leaking from one side of the ball valve. The lower valve cover 16 is used to fix the lower valve stem 15 to enhance its life. The pressure cover 18 supports the valve seat 17, and the valve seat 17 supports the ball core 14. The fixing column 26 and the compression structure 24 on the extended iron sheet 31 ensure that the device will not fall apart to a certain extent, and when the air valve 27 stops working, it provides thrust for separating the upper flange ring 4 and the lower flange ring 29, reducing manual labor.
