The other end of one end of the separable air exhaust sealing valve 9 can be externally connected with air exhaust tools such as an air exhaust tube, an air pump and the like to exhaust the bag body 1. There are various configurations of the separable pneumatic sealing valve 9, and in this embodiment, as shown in fig. 6, the separable pneumatic sealing valve 9 includes a first housing 400, a valve needle 401, a first valve plug 402, and a second valve plug 403. The first housing 400 is a hollow plastic tube. The first housing 400 has a first air inlet 404 at one end and a first air outlet 405 at the other end. One end of the first housing 400 is connected with the other end of the vent nozzle 7 in a sealing manner through threads, that is, the separable suction seal valve 9 can be separated after being connected with the vent nozzle 7 in a sealing manner. The other end of the first housing 400 may be externally connected to a suction tool. The inner wall of the first housing 400 is provided with a first valve plug 402 and a second valve plug 403 which are annular, and the first valve plug 402 and the second valve plug 403 are made of flexible materials such as rubber or silica gel. An air inlet channel 406 which penetrates up and down is formed between the first valve plug 402 and the second valve plug 403, and air in the bag body 1 can pass through the air inlet channel 406 during air extraction. The valve needle 401 is confined in the space between the first valve plug 402 and the second valve plug 403, and the second valve plug 403 can block the valve needle 401 from disengaging from the first outlet port 405 during air extraction.

The other end of the second housing 500 may be externally connected with a suction tool. Flexible valve sheet 501 is fixed to fixing bracket 502 by plug 503. The inner wall of the second shell 500 is provided with a fixed support 502, the fixed support 502 comprises a large ring 506, a small ring 507 and connecting rods 508, the large ring 506 is integrally connected with the inner wall of the second shell 500, the small ring 507 is consistent with the central point of the large ring 506, the small ring 507 is connected with the large ring 506 through at least two connecting rods 508, a third through hole 509 is formed between the two connecting rods 508 and enables air to flow up and down, and a fourth through hole 510 is formed in the middle of the small ring 507. The flexible valve plate 501 is round, is made of flexible materials such as rubber or silica gel and the like, and is attached to the upper end face of the large ring 506 to form sealing. The lower end of the flexible valve plate 501 is connected with a plug 503, and the plug 503 is plugged into a fourth through hole 510 in the middle of the small ring 507 to fix the flexible valve plate 501 on the fixing bracket 502. When the other end of the second housing 500 is externally connected with an air suction tool for air suction, the edge portion of the flexible valve sheet 501 is separated from the upper end of the large ring 506 and is turned upwards under the action of air pressure. The air in the bag body 1 is discharged to the second outlet 505 through the third through-hole 509 of the fixing bracket 502. The air extracting tool continuously extracts air until the air in the bag body 1 is completely extracted and can not be extracted. When the air extracting tool stops extracting air, the edge part of the flexible valve plate 501 which is turned up naturally falls back downwards to be attached to the upper end face of the large ring 506 and keeps a sealing state under the action of external atmospheric pressure. When the air suction is completed, the air suction tool is removed from the other end of the second housing 500, and the second cover 12 is screwed on the other end of the second housing 500, the sealing performance of the separable air suction sealing valve 9 is better.
