[0014] 1. This chemical safety detection gas sealing ring is provided with a sealing ring component group 02 and a connecting component group 03. Since it will be in contact with corrosive gases in the sampling bottle, such as sulfur dioxide, hydrogen sulfide, hydrogen fluoride, etc., it is easy for a small part of the rubber sealing ring to be corroded and damaged due to frequent contact with these gases. At this time, the entire sealing ring needs to be replaced, and the use of sealing rings made of other materials cannot guarantee the same low use cost as rubber sealing rings. In the corresponding designed sealing ring component group 02, when the bottle cap 12 is covered on the bottle body 11 through a threaded cover, the bottle cap 12 and the bottle body 11 will squeeze the sealing ring component group 02 structure, and the outer ring 21, the first sealing member 23, the second sealing member 24, the third sealing member 25 and the fourth sealing member 26 play the role of filling the bottle cap 12 and the bottle body 11. The first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 directly contact the gas inside the bottle body 11. When the bottle body 11 is filled with corrosive gas, only the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 will contact the corrosive gas. When corrosion occurs, only one of the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 needs to be replaced. Compared with the current technology, if a part of the corroded part needs to be replaced, the entire sealing ring needs to be replaced. This technology can greatly reduce the maintenance cost.

[0015] 2. This chemical safety detection gas sealing ring is provided with a sealing ring component group 02 and a connecting component group 03. The current connection between the sealing ring and the sealed bottle cap is unstable. During use, the sealing ring is easy to fall off the sealed bottle cap, affecting use. In the corresponding designed connecting component group 03, a screw 31 passes through the outer ring 21, and then passes through the bottle cap 12 to extend to the outside of the top of the bottle cap 12. The position where the screw 31 extends is connected by a thread and a ring plate 32. The screw 31 and the ring plate 32 can fix the outer ring 21 to the bottle cap 12. When the bottle cap 12 and the bottle body 11 squeeze the connecting component group 03, since the screw 31 contacts the outer ring 21 and the bottle cap 12 through the through hole, it will not affect the sealing of the sealing ring component group 02. When squeezed The end of the screw 31 extending outside the bottle cap 12 will become longer, and the collar plate 32 will release the contact with the bottle cap 12, so that the connecting component group 03 will not affect the extrusion sealing of the sealing ring component group 02. At the same time, due to the fixation of the screw 31 and the collar plate 32 to the outer ring 21, the connection between the outer ring 21 and the bottle cap 12 can be guaranteed to be stable. Through the grooves of the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 contacting the convex ring 22, the positions of the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 can be guaranteed to be stable, and the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 can form a complete ring, which has stability and will not fall off easily after forming the ring.

[0031] Working principle: Due to contact with corrosive gases in the sampling bottle, such as sulfur dioxide, hydrogen sulfide, hydrogen fluoride, etc., the rubber sealing ring is easily corroded and damaged due to frequent contact with these gases. At this time, the entire sealing ring needs to be replaced, and the use of sealing rings made of other materials cannot guarantee the same low cost of use as rubber sealing rings. In the corresponding designed sealing ring component group 02, when the bottle cap 12 is covered on the bottle body 11 through threads, the bottle cap 12 and the bottle body 11 will squeeze the sealing ring component group 02 structure, and the outer ring 21, the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 fill the fine gap between the bottle cap 12 and the bottle body 11 to prevent the inside of the bottle body 11 from Gas leaks from the connecting gap, and the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 directly contact the gas inside the bottle body 11. When the bottle body 11 is filled with corrosive gas, only the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 will contact the corrosive gas.

When the bottle cap 12 and the bottle body 11 squeeze the connecting component group 03, since the screw 31 contacts the outer ring 21 and the bottle cap 12 through the through hole, it will not affect the sealing of the sealing ring component group 02. When squeezed, the screw 31 extends out of the bottle cap 12. The end will become longer, and the ring plate 32 will release the contact with the bottle cap 12, so that the connecting component group 03 will not affect the extrusion sealing of the sealing ring component group 02. At the same time, due to the fixation of the screw 31 and the ring plate 32 to the outer ring 21, the connection between the outer ring 21 and the bottle cap 12 can be guaranteed to be stable. Through the grooves of the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 contacting the convex ring 22, the positions of the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 can be guaranteed to be stable, and the first seal 23, the second seal 24, the third seal 25 and the fourth seal 26 can form a complete ring, which has stability and will not fall off easily after forming the ring.
