Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 5 shown, the present utility model provides a pneumatically based one-inlet multi-outlet valve that can be self-drained. The buoy 3 slides downward from the inside of the outer shell 2. Since the air outlet hole 6 is fitted inside the air outlet sleeve 21, the air blocking hole 4 at the top of the downward-sliding buoy 3 rotates with the air outlet hole 6, and there is a gap between the two sleeved inside the bellows 5, and the gas is discharged from the inside of the air outlet hole 6.

[0024] Specifically, the connecting block 14 is screwed inside the pressing plate 13, and the connecting block 14 injects high-pressure gas into the air inlet 15. The high-pressure gas pushes the sliding rod 22 inside the valve body 1 to slide to the right. The first slider 11 sleeved outside the sliding rod 22 slides to the right, and the first slider 11 presses and closes the top of the second track 20.

[0025] Furthermore, by rotating the bolt 9, the pressing distance of the spring 10 on the sliding rod 22 is achieved.

[0026] Still further, water cannot flow out from the inside of the second water outlet 18 and can only flow out from the bottom end of the first water outlet hole 17. When the injection of high-pressure gas into the valve body 1 stops, it slides to the left under the action of the spring 10, and the water flows into the inside of the first track 19 and flows out from the bottom end of the first water outlet hole 17.

[0027] It should be noted that the first slider 11 presses and closes the top of the second track 20, and at this time, water cannot flow out from the inside of the second water outlet 18.

[0028] It should be noted that the water filter net 8 slides up and down inside the valve body 1.

[0029] It is worth introducing that the slide bar 22 slides left and right inside the cavity of the valve body 1, and the spring 10 is rotatably connected inside the cavity of the valve body 1 to realize the pressing distance of the spring 10 on the slide bar 22.

[0030] Among them, the valve body 1 is a prior art and will not be elaborated; at the same time, the present utility model also includes a power source, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated; the "front, back, left, and right" perspectives of this device are based on Figure 1 the direction shown in the figure.

[0031] Working principle:

[0032] Place the valve body 1 on a flat table, connect and fix the high-pressure air pipe to the air inlet 15, inject water into the inside of the valve body 1 from the direction of the water inlet 16. The inside of the valve body 1 is filled with water, and the water squeezes the water filter net 8 to push up the floating buoy 3 at the top through the connecting rod 7. The air blocking hole 4 inside the square groove of the floating buoy 3 is connected to the air outlet hole 6, and the water squeezes the gas and discharges it from the inside of the air outlet hole 6 on the outer side of the housing 2. When the water level drops, the floating buoy 3 slides downward from the inside of the housing 2. Since the air outlet hole 6 is embedded in the inside of the air outlet sleeve 21, the right side of the air outlet hole 6 does not move, the air blocking hole 4 rotates, the top groove of the floating buoy 3 abuts against the air blocking hole 4, the floating buoy 3 slides, the air blocking hole 4 and the air outlet hole 6 rotate, and the gas is discharged from the gap between the two inside the corrugated pipe 5;

[0033] When it is necessary to deflect the direction of the water between the valve bodies 1, start the outer high-pressure air pipe and inject high-pressure gas into the air inlet 15. The high-pressure gas pushes the slide bar 22 inside the valve body 1 to slide to the right. The first slider 11 sleeved outside the slide bar 22 slides to the right. The first slider 11 abuts against and closes the top of the second track 20. At this time, the water cannot flow out from the inside of the second water outlet 18 and can only flow out from the bottom end of the first water hole 17. When stopping injecting high-pressure gas into the valve body 1, it slides to the left under the action of the spring 10. The second slider 12 outside the slide bar 22 slides to the left, and the water flows into the inside of the first track 19 and flows out from the bottom end of the first water hole 17. When it is necessary to adjust the drainage volume, the pressing distance of the spring 10 on the slide bar 22 can be realized by rotating the bolt 9.

[0034] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0035] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
