[0032] like Figure 3 , Figure 4 and Figure 5 As shown, the automatic air vent valve for the basement air conditioning water system includes a connecting device. The connecting device includes a mounting base 2, a filter screen 5, a retaining ring 6, and a connecting pipe 8. The mounting base 2 is located at one end of the valve body 1 and the end of the drain pipe 12. A baffle is provided on the outer side of the bottom of the mounting base 2. A buckle 3 is provided on the upper edge of the mounting base 2. A movable ball 4 is provided in the middle of the mounting base 2. The filter screen 5 is located inside the mounting base 2 to filter impurities in the water. The retaining ring 6 is fitted onto the outer side of the mounting base 2. The upper end of the retaining ring 6 is limited by the buckle 3. The lower end of the retaining ring 6 is connected to the mounting base 2 by a first spring 7. The connecting pipe 8 is installed on the mounting base 2. A grooved convex ring is provided on the outer side of the upper end of the connecting pipe 8 for easy rotation. The lower end of the connecting pipe 8 is provided with a concave annular groove that fits with the ball 4. The inner side of the connecting pipe 8 is threaded for connecting to an external water inlet pipe.

[0033] In a specific embodiment: when in use, the water pipe is connected to the connecting pipe 8 through the thread inside the connecting pipe 8, then the stop ring 6 is pulled down and the first spring 7 is compressed, then the connecting pipe 8 is inserted into the mounting seat 2, the connecting pipe 8 pushes away the ball 4, then the stop ring 6 is reset, the stop ring 6 pushes the ball 4 to reset, so that the ball 4 clamps the lower end annular sliding groove of the connecting pipe 8, thereby installing the connecting exhaust valve.

[0034] As shown in Figure 3 and Figure 6 , the automatic exhaust valve for the air conditioning water system of the basement comprises a separation device, the separation device comprises a flow channel 9, a branch pipe 10, a separation chamber 11, a drain pipe 12 and an elastic sheet 14, the flow channel 9 is arranged below the valve body 1, the first end of the flow channel 9 is a funnel-shaped structure with a large head and a small tail, which can accelerate the water flow through the flow channel 9, the tail end of the flow channel 9 is provided with two outlets connected to the bottom of the separation chamber 11, the outlets are located on both sides of the drain pipe 12, and the outlets are funnel-shaped structures with a small head and a large tail, which can make the water flow slow down and flow out of the outlets, the branch pipe 10 is connected to both sides of the flow channel 9, and the branch pipe 10 is a “half peach heart shape”, which can prevent the water flow in the flow channel 9 from flowing back, the separation chamber 11 is provided with an exhaust hole 13 at the upper end, the inlet of the drain pipe 12 is located at the lower end of the separation chamber 11, and the lower end of the elastic sheet 14 is fixed to the outside of the exhaust hole 13.

[0035] In a specific embodiment: when the water flow enters the flow channel 9, the water flow is accelerated through the funnel-shaped structure with a large head and a small tail at the first end of the flow channel 9, part of the water flow will enter the branch pipe 10 when the water flow flows through the branch pipe 10, and then the water flow is combined with the water flow in the flow channel 9 after passing through the branch pipe 10, and then the water flow is slowed down and discharged into the separation chamber 11 through the two outlets of the flow channel 9.

[0036] In this process, the water flows collide and merge with each other, which makes the waste gas in the water flow more easily separated out, thereby forming small bubbles that rise along the flow channel 9 and are discharged into the separation chamber 11.

[0037] When the water flow enters the separation chamber 11, the water surface at the bottom of the separation chamber 11 rises, and when the water surface rises to the opening of the drain pipe 12, the upper cavity of the separation chamber 11 above the opening of the drain pipe 12 is relatively sealed due to the blockage of the elastic sheet 14 outside the exhaust hole 13, so that the water flow cannot enter the upper cavity, but the water flow can be discharged through the drain pipe 12.

[0038] The water surface at the bottom of the separation chamber 11 can make the waste gas rise and enter, thereby increasing the air pressure above, and when the air pressure increases to push away the elastic sheet 14, the waste gas is discharged out of the valve body 1 through the exhaust hole 13, and when the waste gas is discharged, the liquid level outside the drain pipe 12 will rise, and then the air pressure decreases, the elastic sheet 14 returns to normal, and the liquid level in the separation chamber 11 returns to normal.

[0040] In specific embodiments: the pressing ring 15 presses part of the elastic sheet 14 through the second spring 16, so that the elastic sheet 14 is not easy to push away, when the rotating wheel 17 is rotated, the pressing ring 15 is driven to rotate, and the contact area with the elastic sheet 14 is changed through the spiral edge of the pressing ring 15, so as to adjust the frequency of exhaust gas discharge and the amount of exhaust gas discharged each time.

[0041] Working principle: in use, the external water pipe is connected through the threads on the inner side of the connecting pipe 8, then the stop ring 6 is pulled down and the first spring 7 is compressed, then the connecting pipe 8 is inserted into the mounting seat 2, so that the connecting pipe 8 pushes away the ball 4, then the stop ring 6 is reset, so that the stop ring 6 pushes the ball 4 to reset, so that the ball 4 clamps the annular sliding groove at the lower end of the connecting pipe 8, so as to install the exhaust valve, then the water flow enters the flow channel 9, and is accelerated through the funnel-shaped structure with the large head at the front end and the small tail at the rear end of the flow channel 9, when the water flow flows through the branch pipe 10, part of the water flow will enter the branch pipe 10, and then the water flow in the branch pipe 10 is combined with the water flow in the flow channel 9, and then the water flow is slowed down through the two outlets of the flow channel 9 and discharged into the separation chamber 11, in this process, the water flow collides and combines with each other, so that the exhaust gas in the water flow is more easily separated out, thereby forming small bubbles rising along the flow channel 9 and being discharged into the separation chamber 11, then the water flow entering the separation chamber 11 makes the water surface at the bottom of the separation chamber 11 rise, and when the water surface rises to the opening of the drain pipe 12, a relatively sealed cavity is formed in the separation chamber 11 above the opening of the drain pipe 12 due to the blockage of the elastic sheet 14 outside the exhaust hole 13, so that the water flow cannot enter the cavity above, but the water flow can be discharged through the drain pipe 12, then the water surface at the bottom of the separation chamber 11 can make the exhaust gas rise and enter, so as to increase the air pressure above, when the air pressure increases to push away the elastic sheet 14, the exhaust gas is discharged through the exhaust hole 13 and the valve body 1, and when the exhaust gas is discharged, the liquid level outside the drain pipe 12 will rise, then the air pressure decreases, the elastic sheet 14 returns to the original position, and the liquid level in the separation chamber 11 returns to the original position, when adjusting, the pressing ring 15 presses part of the elastic sheet 14 through the second spring 16, so that the elastic sheet 14 is not easy to push away, when the rotating wheel 17 is rotated, the pressing ring 15 is driven to rotate, and the contact area with the elastic sheet 14 is changed through the spiral edge of the pressing ring 15, so as to adjust the frequency of exhaust gas discharge and the amount of exhaust gas discharged each time.
