[0002] The air valve is a component in the compressor used to control the flow of gas in and out of the cylinder. It is mainly composed of a valve seat, a valve plate, a spring and a lift limiter.

[0003] For example, a compressor air valve with the authorization announcement number "CN103671034B" has a first air vent used to communicate with the exhaust port of the compressor, and a second air vent is provided on the air inlet chamber, and the second air vent is used to communicate with the suction port of the compressor. The valve plate is movably provided at the exhaust port on the valve seat to open or close the exhaust port, and the valve stem is movably provided at the suction port of the valve seat to open or close the suction port. Compared with the existing piston compressor, the air valve has a simple structure, fewer parts, easy assembly and high reliability. However, when the compressor air valve is used, the flow area of ​​the valve body is fixed, which limits the working efficiency of the compressor and requires replacement of the compressor air valve. Therefore, the compressor air valve needs to be replaced every time the flow area is adjusted, which reduces the adaptability of the compressor air valve and increases the difficulty of using the compressor air valve.

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Embodiment 1:

[0021] See also Figure 1-5In the present embodiment, a compressor air valve capable of increasing the flow area includes an outer shell 1 and a through port 5. The outer shell 1 is provided with a through port 5 on both sides of the front surface, and a slide groove 4 is provided on both sides of the front surface. The inner wall of the slide groove 4 is connected with an opening and closing structure 2. The outer wall of the outer shell 1 is provided with a thread 7 at the rear, and the thread 7 facilitates the threaded connection between the outer shell 1 and the compressor air pipe. The outer surface of the outer shell 1 is connected with a control structure 3, and the outer wall of the control structure 3 is connected with a bracket 6.

[0022] The opening and closing structure 2 includes a square plate 201 and a straight rod 202. The outer wall of the square plate 201 is slidably engaged with the inner wall of the slide groove 4. The square plate 201 is subjected to force to slide up and down through the inner wall of the slide groove 4. The inner wall of the square plate 201 is fixedly connected to the inner end of the straight rod 202. A horizontal plate 203 is fixedly connected to the front of the square plate 201. Bolts 204 are respectively threadedly connected to the left and right sides of the front of the horizontal plate 203. The bolts 204 are subjected to force to rotate back and forth through the horizontal plate 203, pushing the horizontal plate 203 to facilitate the movement of the square plate 201. The rear of the outer wall of the bolt 204 is plugged into the front circular opening of the housing 1, and the rear of the outer wall of the straight rod 202 is slidably connected to the inner wall notch of the slide groove 4.

[0023] By means of the opening and closing structure 2, the bolt 204 is rotated forward through the horizontal plate 203, so that the rear of the outer wall of the bolt 204 is separated from the circular opening on the front side of the shell 1, and then the horizontal plate 203 is pushed outward. The horizontal plate 203 is forced to slide the square plate 201 outward on the inner wall of the slide groove 4. At this time, the square plate 201 gradually opens the slide groove 4. At this time, the air vents on the front side of the shell 1 are increased, and the flow area is increased. Subsequently, the bolt 204 is rotated backward through the horizontal plate 203, so that the rear of the outer wall of the bolt 204 is plugged into the circular opening corresponding to the front side of the shell 1, thereby improving the adaptability of the compressor valve and reducing the difficulty of using the compressor valve.

[0024] The control structure 3 includes a round rod 301 and a cylinder 302. The outer wall of the round rod 301 is slidably connected to the front side of the outer shell 1. The round rod 301 slides back and forth through the front side of the outer shell 1 under force. The front side of the round rod 301 is fixedly connected to the output end of the cylinder 302. The model of the cylinder 302 is selected according to the usage requirements. The rear end face of the round rod 301 is fixedly connected to a round plate 303. The outer wall of the round plate 303 fits the inner wall of the outer shell 1. The left and right sides of the outer wall of the cylinder 302 are respectively fixedly connected to the inner front end of the bracket 6, and the rear end face of the bracket 6 is fixedly connected to the front side of the outer shell 1.

[0025] Working principle:

[0026] The outer shell 1 is threadedly connected to the air pipe position of the compressor through the thread 7 at the rear of the outer wall to complete the fixing of the outer shell 1.

[0027] Air valve use:

[0028] The working output end of the cylinder 302 moves backward with the round rod 301 through the front of the shell 1, and the moving round rod 301 moves the circular plate 303 backward in contact with the inner wall of the shell 1, so that the circular plate 303 moves to a place with a larger inner diameter at the rear of the shell 1. At this time, the inside of the shell 1 is opened, and the compressor is started to intake or exhaust air through the shell 1. After the work is completed, the output end of the cylinder 302 moves forward with the round rod 301, and the round rod 301 moves forward with the circular plate 303, so that the circular plate 303 is inserted back to the original position of the inner wall of the shell 1 to complete the closing of the air valve.

[0029] Air valve flow area adjustment:

[0030] The bolt 204 is rotated forward through the cross plate 203, so that the rear of the outer wall of the bolt 204 is separated from the circular opening on the front side of the shell 1, and then the cross plate 203 is pushed outward. The cross plate 203 is forced to slide the square plate 201 outward on the inner wall of the slide groove 4. At this time, the square plate 201 gradually opens the slide groove 4. At this time, the air vents on the front side of the shell 1 are increased, and the flow area is increased. Subsequently, the bolt 204 is rotated backward through the cross plate 203, so that the rear of the outer wall of the bolt 204 is plugged into the circular opening corresponding to the front side of the shell 1. When the flow area is reduced, the cross plate 203 is pushed inward to bring the square plate 201 back to its original position, and then the bolt 204 is plugged into the circular opening at the original position.

[0031] Embodiment 2:

[0032] See also Figure 1-5 In this embodiment, a compressor air valve capable of increasing the flow area further comprises a circular ring 8, the inner wall of the circular ring 8 being fixedly connected to the outer wall of the outer shell 1.

[0033] Working principle:

[0034] After the outer shell 1 is connected to the compressor air pipe through the thread 7, the ring 8 will be tightly pressed against the end of the compressor air pipe. The ring 8 plays a sealing role through its own rubber material, which can prevent water from entering through the connecting gap between the compressor air pipe and the outer shell 1.
