It mainly uses the mixing of gas and liquid and other arbitrary fluids, and the mixing of gas and liquid in different proportions to achieve a certain atomization state. Due to its strong applicability, simple operation, high efficiency and other advantages, it is increasingly widely used. The current mixed atomization device not only has a single function, but also has difficulty in controlling the mixing ratio, resulting in unsatisfactory mixed atomization effect.

[0003] In recent years, in order to improve the mixed atomization effect and application range of the multi-fluid control device, paddle wheels, spiral guide vanes or tapered or expanding curved surfaces inside the pipeline are integrated inside the mixing device to improve the mixed atomization effect. For example, the Chinese utility model patent with the authorization announcement date of January 14, 2022 and the authorization announcement number of CN215516687U discloses a multi-fluid pipeline static mixer, which is mainly used for mixing between liquids. By integrating paddle wheels, spiral guide vanes and other structures, the mixing effect is good.

[0068] When the fluid in the valve body intermediate flow channel one 11.2 and the valve body intermediate flow channel two 11.12 reaches the end of the anti-backflow valve core one 15.1 and the anti-backflow valve core two 15.2, the pressure of the fluid in the flow channel is increased. When the pressure overcomes the elastic force of the spring one 14.1 and the spring two 14.2 respectively, the fluid in the valve body intermediate flow channel one 11.2 and the valve body intermediate flow channel two 11.12 pushes away the anti-backflow valve core one 15.1 and the anti-backflow valve core two 15.2 respectively, so that the fluid flows through the inner hole of the anti-backflow valve core one 15.1 and the anti-backflow valve core two 15.2 to reach the valve body outlet flow channel one 11.4 and the valve body outlet flow channel two 11.11 respectively.

[0069] After the valve body outlet flow channel one 11.4 is blocked, the fluid in the valve body outlet flow channel one 11.4 passes through the valve body connecting large flow channel 11.3, and then passes through the valve body connecting small flow channel two 11.5, the valve body connecting small flow channel three 11.6, the valve body connecting small flow channel four 11.7, the valve body connecting small flow channel five 11.8, the valve body connecting small flow channel six 11.9, and the valve body connecting small flow channel one 11.10 respectively to reach the periphery of the valve body outlet flow channel two 11.11, and is fully mixed with the fluid in the valve body outlet flow channel two 11.11. The mixed fluid flows out of the valve body 11 through the valve body outlet flow channel two 11.11.

[0070] The number of the valve body inlet flow channel, the intermediate flow channel and the outlet flow channel in the multi-mode mixed control atomization device includes but is not limited to two groups, and the number of the control valve core and the anti-backflow valve core includes but is not limited to two groups.

[0071] The fluid is not limited to any single fluid, gas or liquid, and the combination of gas and different liquids can also be used.

[0072] The number of the valve body connecting small flow channel in the valve body includes but is not limited to four, and the number of groups includes but is not limited to one group.

[0073] The mode switching in the multi-mode mixed control atomization device is not limited to a single fluid mode or a gas and different liquid mixed atomization flow mode.

[0074] The control and adjustment device in the multi-mode mixed control atomization device is not limited to the manual control of the rotating handle, and can be controlled by a solenoid valve, or can be liquid or gas controlled, wherein the opening range can be from 0 to maximum.

[0075] In the multi-mode mixed control atomization device, as described above, by rotating the rotating handle, the valve core is spirally rotated in the conversion joint, the relative position of the valve core and the valve body flow channel is changed, the flow area is changed, and the flow of the fluid in each flow channel is changed. Since the angle and the number of turns of the spiral rotation are relatively fixed and controllable, the control of the flow has great operability in a certain range, and the precise adjustment of the flow from 0 to the maximum value can be realized.

[0076] Two identical valve cores are installed on the valve body, by passing two different types of fluids such as gas and different types of liquid, by rotating the adjusting handle respectively, the flow rate of each fluid can be realized, and in order to ensure the mixing atomization effect, a plurality of mixing holes are opened at the mixing position of the flow channel in the valve core, which can ensure the full mixing and atomization of gas and liquid. In addition, for different application conditions, by rotating the rotating handle of the control valve core, the free switching of the flow mode of single fluid flow and mixed flow of multiple fluids can be realized. Considering the case that the pressure in the flow channel is increased due to the blockage of the flow channel, which causes the reverse flow and mutual flow of different flow channels, a backflow prevention valve core is arranged in each single fluid flow channel to prevent the mutual flow of the fluids in the two single flow channels, thereby ensuring the safety of the flow.

[0077] In a multi-mode mixed control atomization device, the mode switching of gas, liquid and other single fluid flow, gas and liquid mixed atomization flow can be realized, wherein the flow rate of any fluid can be accurately controlled from 0 to maximum, the mixed fluid can be adjusted at any ratio, and the device has the advantages of strong applicability, wide application range and multiple working modes. A plurality of mixing holes are opened at the mixing position, the mixing and atomization effect is good, and the safety is high.

[0078] A multi-mode mixed control atomization device control method, using the multi-mode mixed control atomization device of any one of the above, including a mixed control atomization implementation method: any several liquids and gases pass through the corresponding medium flow channels respectively, the relative position between the wedge-shaped bottom of the flow regulating valve core and the stepped platform of the medium flow channel is changed by rotating the flow regulating valve core, so that the area of the flow channel changes, the area of the flow channel can be adjusted from 0 to the maximum range, or the area of the flow channel is adjusted by an electromagnetic control valve or a hydraulic control valve or a pneumatic control valve, so as to control the flow rate of the passing fluid, so that the ratio of liquid to gas changes when mixed and atomized, thereby realizing the adjustment of mixed control atomization.

[0079] Further, it further includes a multi-mode switching implementation method: by rotating each flow regulating valve core, the relative position between the wedge-shaped bottom of each flow regulating valve core and the stepped platform of the corresponding medium flow channel is changed, so that the area of the flow channel increases or decreases, or the area of the flow channel is adjusted by an electromagnetic control valve or a hydraulic control valve or a pneumatic control valve, the area of the flow channel can be adjusted from 0 to the maximum range, when the area of a certain flow channel is 0 and the area of another flow channel is not 0, it is a single fluid atomization mode; when the area of each flow channel is not 0, it is a gas and different liquid mixed atomization flow mode.

[0080] Further, the backflow prevention method is also included: when the pressure inside the atomization outlet is increased due to blockage or other reasons, and the pressure is higher than the inlet pressure of the medium flow channel, the fluid pressure cannot overcome the spring force of the backflow prevention valve, and the backflow prevention valve will automatically close the medium flow channel, so that each medium flow channel is completely blocked, preventing the high-pressure mixed atomized fluid from flowing into any single fluid; when the pressure in any medium flow channel is too high, the backflow prevention valve will open, while the other backflow prevention valves will close, so that the various fluids in the medium flow channel will not flow into each other.

[0081] A multi-mode mixed control atomization device control method, when a multi-mode mixed control atomization device including two medium flow channels is used, the mixed control atomization implementation method is:

[0082] When any liquid and gas pass through the valve body liquid inlet flow channel one 11.1 and the valve body inlet flow channel two 11.13 to reach the flow channel formed by the valve body 11 and the flow regulating valve core one 2.1 and the flow regulating valve core two 2.2, the relative positions of the wedge-shaped bottom of the flow regulating valve core one 2.1 and the flow regulating valve core two 2.2 and the stepped plane of the valve body 11 are changed by rotating the rotary handle one 1.1 and the rotary handle two 1.2, so that the area of the flow channel changes, and the area can be adjusted from 0 to the maximum range, so as to control the flow of the fluid passing through, so that the ratio of liquid to gas changes during mixed atomization. Thus, the mixed control atomization adjustment is realized.

[0083] The multi-mode switching implementation method is:

[0084] When the rotary handle one 1.1 or the rotary handle two 1.2 is rotated, the relative positions of the wedge-shaped bottom of the valve core flow regulating valve core one 2.1 or the flow regulating valve core two 2.2 and the stepped plane of the valve body 11 can be changed, so that the area of the flow channel increases or decreases, and the area can be adjusted from 0 to the maximum range. When the area of a certain flow channel is 0, and the area of another flow channel is not 0, it is a single-fluid flow mode; when the areas of the two flow channels are not 0, it is a gas and different liquid mixed atomization flow mode.

[0085] The backflow prevention implementation method is:

[0086] When the pressure inside the valve body 11 mixing atomization pipeline is increased due to blockage of the mixing atomization flow channel or other reasons, when the pressure is higher than the pressure of the valve body liquid inlet flow channel one 11.1 and the valve body gas inlet flow channel two 11.13, the liquid and gas of the valve body liquid inlet flow channel one 11.1 and the valve body gas inlet flow channel two 11.13 cannot overcome the spring force of the spring one 14.1 or the spring two 14.2, and the corresponding anti-backflow valve core one 15.1 or the anti-backflow valve core two 15.2 will be closed, causing the valve body liquid inlet flow channel one 11.1 and the valve body gas inlet flow channel two 11.13 to be completely blocked, preventing the high-pressure mixed atomization fluid from flowing into any single fluid in the valve body liquid inlet flow channel one 11.1 and the valve body inlet flow channel two 11.13.

[0087] When the pressure of the liquid and gas in any one of the valve body liquid inlet flow channel one 11.1 or the valve body inlet flow channel two 11.13 is too high, the anti-backflow valve core one 15.1 or the anti-backflow valve core two 15.2 will be opened, and the anti-backflow valve core two 15.2 or the anti-backflow valve core one 15.1 will be closed, so that the liquid and gas in the two single flow channels will not flow into each other, playing a safety protection role.

The above is only a preferred embodiment of the present application and is not intended to limit the present application.
