The gas enters the exhaust valve seat 102 through the opening set on the joint 101, and an exhaust gap is formed between the plugging part 113 and the first sliding part 108 and the exhaust channel 104. The exhaust gap is connected to the exhaust channel 104, and the gas entering the exhaust valve seat 102 passes through the exhaust gap and the exhaust channel 104 in turn and is discharged to the outside of the exhaust valve; under the support of the connecting part 112 and the action of its own gravity, during the process of the gas entering the exhaust valve being discharged, the plugging part 113 located in the limiting area does not contact the first sliding part 108 and the air inlet of the exhaust channel 104. , thereby ensuring that the gas in the working container can be completely discharged; as the gas in the working container is discharged, the liquid in the working container is slowly filled into the exhaust valve seat 102 through the joint 101, and the first sliding portion 108 moves vertically upward under the action of the liquid driving force. When the first sliding portion 108 moves to contact the blocking component 107 located in the limiting area, the first sliding portion 108 drives the blocking component 107 to move vertically upward until it is tightly fitted with the air inlet of the exhaust duct 104, and then blocks the exhaust duct 104, thereby preventing the liquid entering the exhaust valve seat 102 from overflowing.

[0043] A sliding seal is installed on the guide rod, which is used to seal the gap between the guide rod and the joint 101 to prevent the liquid entering the exhaust valve seat 102 from entering the gap between the guide rod and the joint 101 along with the movement of the connecting part 112 .

[0044] The connecting portion 112 is provided with a through groove 114.

There are two second springs 116, and the two second springs 116 are symmetrically connected to the left and right ends of the second sliding part 115. When the second spring 116 is in a normal state or a slightly extended state under the action of the gravity of the second sliding part 115, the exhaust gap is formed between the second sliding part 115 and the blocking part 113 located in the limiting area under the connection limit of the second spring 116. When the liquid in the working container is slowly filled into the exhaust valve seat 102 through the joint 101, the second sliding part 115 moves vertically upward under the action of the driving force of the liquid until it contacts the blocking part 113 located in the limiting area. The second spring 116 is moved vertically upward to contact the blocking part 113 located in the limiting area. 6 compression; the blocking component 107 is driven by the second sliding part 115 to move vertically upward until it is tightly fitted with the air inlet of the exhaust channel 104 to block the exhaust channel 104, thereby preventing the liquid entering the exhaust valve seat 102 from overflowing; by setting the second spring 116, it is possible to avoid that the second spring 116 blocks the liquid entering the valve body seat, which will affect the first sliding part 108 driving the blocking part 113 to block the exhaust channel 104; in order to facilitate the liquid entering the exhaust valve seat 102 to push the driving component to move vertically upward, the second spring 116 adopts a conventional spring in the prior art.
