When the pressure in the transport pipe 1 is too high, the sealing block 41 moves in the direction away from the transport pipe 1 under the action of the air pressure in the transport pipe 1 until the sealing block 41 is separated from the connecting pipe 3, the supporting spring 43 is compressed, the connecting pipe 3 is communicated with the transport pipe 1, and at the moment, the natural gas in the transport pipe 1 can be diffused into the receiving airbag 2. When the air pressure in the conveying pipe 1 is small, the sealing block 41 moves towards the direction close to the connecting block under the action of the supporting spring 43 until the sealing block 41 is tightly clamped with the connecting pipe 3 again, and at the moment, the connecting pipe 3 and the conveying pipe 1 are in a closed state. Under the action of the supporting spring 43, the natural gas in the conveying pipe 1 is automatically diffused.
The transition duct 21 is gradually flared in a direction away from the connecting tube 3. Since the greater the air pressure in the transport pipe 1 is, the farther the distance that the sealing block 41 moves in the direction away from the connecting pipe 3 under the action of the air pressure in the transport pipe 1 is, after the sealing block 41 enters the transition pipeline 21, the distance between the sealing block 41 and the side wall of the transition pipeline 21 gradually increases as the sealing block 41 moves in the direction away from the connecting pipe 3.

When the volume of the receiving airbag 2 is continuously reduced, the clamping block 52 is gradually separated from the clamping groove 241. The clamping block 52 pulls the clamping plug 24 to move so as to realize reset clamping between the clamping plug 24 and the connecting hole 23.

When the worker observes that the identification section 71 is located on the outer side of the installation box 6, the clamping block 52 is clamped with the clamping groove 241 at the moment, the clamping block 52 is about to push the clamping plug 24 to be separated from the connecting hole 23, and the fact that the exhaust tube 51 is about to enter the bearing air bag 2 is proved; at this time, the air pump can be started to perform air extraction and collection on the natural gas in the receiving air bag 2.
A dispersion hole 61 is formed in one side wall of the installation box 6, and a sealing plug 62 is clamped in the dispersion hole 61. During the process of the suction pipe 51 entering the receiving airbag 2, the natural gas in part of the receiving airbag 2 may overflow the receiving airbag 2. At this time, natural gas overflowing from the receiving airbag 2 enters the installation box 6, and when the natural gas in the installation box 6 needs to be diffused, the sealing plug 62 is pulled to be separated from the diffusion hole 61. Because the natural gas overflowing into the installation box 6 from the receiving air bag 2 is very little, the resource waste is hardly caused.
