Detailed Description

For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting description of the features of the present invention is now provided in combination with the drawings of the present invention:

as shown in fig. 1, the carbon dioxide aluminum cylinder valve comprises a valve body 1, wherein the valve body 1 is provided with a channel 11 which is through from top to bottom, a mandril 2 which extends from top to bottom extends into the upper end of the channel 11, the channel 11 comprises an upper cavity 111 and a lower cavity 112 which can be communicated with each other, a piston 3 which extends from top to bottom is installed at the upper end of the lower cavity 112, a spring 4 which extends from top to bottom is sleeved outside the piston 3, the mandril 2 is positioned in the upper cavity 111 and used for pressing down the piston 3, nuts 5 which are distributed from top to bottom and positioned outside the mandril 2, a press cap 6 and a base 7 are also installed in the upper cavity 111, the nuts 5 are in threaded connection with the valve body 1, a sealing ring 8 is installed between the middle part of the mandril 2 and the press cap 6, the left side and the right side of the upper end of the valve body 1 are provided with a vent hole 12, the press cap 6 and the upper cavity 111 are sequentially communicated from outside to inside, the base 7 is provided with each other, a through hole 71 which is through from top to bottom is formed between the outer wall of the lower end of the mandril 2 and the inner wall of the base 7, a gap is reserved between the outer wall of the lower end of the mandril 2, and the lower end of the piston 3 is in contact with the lower end of the base 7 and blocks the opening 71 of the lower end of the base 7.

The spring 4 is clamped between the outer wall of the upper end of the piston 3 and the inner wall of the valve body 1. After a switch of the soda water machine is pressed down, the dioxygen ejector rod 2 is driven to move downwards, the ejector rod 2 drives the piston 3 to move downwards, and the spring 4 is compressed.

In order to facilitate the alignment of the top rod 2 with the piston 3, the middle of the upper end of the piston 3 is provided with a jack 31 with an upward opening, and the lower end of the top rod 2 extends into the jack 31.
