[0014] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0015] Example

[0016] like Figure 1 As shown, a fluid intelligent formula valve includes a valve body 13, a valve core 14 and a spring 15, a pull rod 1 is provided at the upper end of the valve body 13, the lower end of the pull rod 1 is connected to the valve core 14 arranged inside the valve body 1, the lower end of the valve core 14 is connected to a movable rod 2, a No. 1 back-suction cavity 11 is provided inside the movable rod 2, and a back-suction movable cover 4 is provided at the lower end of the movable rod 2, the upper end of the back-suction movable cover 4 is connected to the upper end of the inner part of the movable rod 2 through a spring 15, a fixed seat 3 is connected to the lower end of the outer side of the valve body 13, the upper end of the fixed seat 3 is connected to the valve body 13 through a fixed seat cover 9, a small valve switch 5 is connected to the lower end of the movable rod 2, and the movable rod 2 below the small valve switch 5 is connected to the movable rod cover 6, the movable rod 2 below the movable rod cover 6 is connected to the large valve switch 7, and a small valve nozzle 8 is connected to the valve body 13 below the large valve switch 7.

[0017] A second suction cavity 12 is provided in the valve body 1 to facilitate the large valve to suck back the residual material. A ball valve 10 is connected to one side of the fixed seat 3 to facilitate feeding. The valve body 13 is made of alloy steel to ensure that its structural strength is qualified. A spring 15 is provided on the outside of the pull rod 1 between the movable rod 2 and the valve body 13 to facilitate the movement of the pull rod 1.

[0018] Specifically, when in use, the fluid intelligent formula valve has a pull rod 1 on the top of the intelligent valve, which drives the movable rod 2 and the movable rod cover 6 to move upward, so that the air in the No. 1 back-suction cavity 11 is discharged, and prepares for the small valve to back-suction the residual material, and all valves are still closed; when the pull rod 1 continues to be pulled upward, the small valve switch 5 moves upward to open, and the liquid flows out of the small valve 8; the pull rod 1 continues to be pulled upward, driving the movable rod cover 4 to move upward to discharge the air in the No. 2 back-suction cavity 12 to prepare for the large valve to back-suction the residual material, while not affecting the small valve flow; the pull rod 1 continues to be pulled upward, driving the large valve switch 7 to open, and at this time the large and small valves are simultaneously Open and carry out mass production; when the flow rate is close to the production volume, the pull rod 1 moves downward to close the large valve switch 7; the pull rod 1 continues to move downward, and the No. 2 back-suction cavity 12 expands under the action of the spring, generating back-suction so that the liquid on the surface and around the small valve 8 is sucked into the valve to avoid residual material balls; the pull rod 1 continues to move downward, and the No. 1 back-suction cavity 11 expands under the action of the spring, generating back-suction so that the liquid at the mouth of the small valve 8 is sucked into the valve to avoid residual material balls; if the production demand is not reached, the small valve 8 can be repeatedly opened and closed and the liquid at the mouth of the small valve 8 will be sucked into the valve at the same time to avoid residual material balls and meet the precision requirements.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
