A valve structure capable of being controlled in multiple ways is disclosed, as shown in figures 1 to 7, and comprises a valve body 1, a valve core 2 is arranged in a valve cavity of the valve body, the valve core is driven by a driving part 3 on the valve body, and a sealing part 4 is arranged between the driving part and the valve body;
the valve core comprises a body of which the outer circumferential surface is matched with the valve cavity, and a liquid passing channel 5 is arranged in the body; an upper liquid passing structure 6 and a lower liquid passing structure 7 are arranged on the body, and an inlet 8 is arranged on the valve body corresponding to the liquid passing channel of the body; the liquid passing channel adopts a blind hole structure, namely, the lower end of the valve core is opened, and the upper end of the valve core is of a closed structure.
The upper liquid passing structure comprises an upper liquid outlet 9 penetrating through the liquid channel along the radial direction, and an upper ring groove 10 communicated with the upper liquid outlet is arranged around the outer circumferential surface of the valve core;
the lower liquid passing structure comprises a lower liquid outlet 11 penetrating through the liquid channel along the radial direction, and a lower annular groove 12 communicated with the lower liquid outlet is arranged around the outer circumferential surface of the valve core;
the valve body is also provided with a first outlet 13, a second outlet 14 and a third outlet 15; when the valve core is positioned at the topmost end of the valve cavity, each outlet is communicated with the liquid passing channel; when the valve core is at a high position, the lower liquid outlet is communicated with the second outlet, and the upper liquid outlet is not communicated with the first outlet; when the valve core is positioned at the middle position, the upper liquid outlet is communicated with the first outlet on the valve body, and the lower liquid outlet is not communicated with the second outlet; when the valve core is at a low position, the lower liquid outlet is communicated with a third outlet on the valve body; when the valve core is positioned at the bottommost end, the inlet is not communicated with any outlet. It should be noted that the ports are in communication with the respective outlets, meaning that the respective annular groove portions serve as transitions that enable fluid or gas exiting the ports to communicate with the respective outlets.
The specific control principle is as follows: the control assembly drives the driving piece to act, and then the action of the valve core is realized. As shown in fig. 1, when the valve core is at the topmost position of the valve cavity, the valve core does not cover any outlet (according to the actual design requirement, only the lower liquid port is communicated with the first outlet), and at this time, the first outlet, the second outlet and the third outlet are all communicated with the inlet;

as shown in fig. 5, when the valve core is adjusted downward, the valve core reaches the neutral position, the upper outlet is connected to the first outlet, and the lower part of the lower outlet of the body covers the second outlet, so that the first outlet and the third outlet discharge liquid, and the second outlet does not pass through the liquid channel.
As shown in fig. 6, when the valve core is continuously adjusted downward, the valve core reaches a low position state, the lower liquid outlet is communicated with the third outlet, and at this time, the body covers the first outlet and the second outlet, and only the third outlet discharges liquid.
As shown in fig. 7, when the valve core is further adjusted downward, the inlet is directly communicated with the liquid passing channel when the valve core reaches the bottom end, and the valve is in a closed state because each outlet is not communicated with any liquid outlet at this time.
Based on above, the combination formula that this valve structure can be convenient realization multiple export is gone out liquid, and optional leeway is big, and the ease for use is strong, and when system design, the effectual pipeline structure that has simplified has improved design efficiency, has reduced the degree of difficulty of installation and construction, and owing to do not have too much logic control components and parts and pipeline, only need utilize driving piece action case to remove, can realize corresponding export selection for pipeline system stability can be better.

In an alternative embodiment, the control assembly includes an electric actuator, and the actuator is used to control the actuation of a driving member, such as a linear actuator, to automatically control the opening and closing of the valve and to select the corresponding outlet. Of course, in an alternative embodiment, a manually actuated form may be used, such as a threaded formation 17 on the valve body, the actuating member being threadedly connected to the valve body, and the control assembly including a handle for screwing the actuating member.
The inlet is arranged at the bottom of the valve body, and the diameter of the inlet is smaller than the inner diameter of the valve cavity. The bottom of the valve core can be designed to be conical, and when the valve core moves to the lowest end, the valve core can be sealed with the outlet to close the valve.
The valve core is processed by finish machining, and the roughness of the outer surface of the valve core is less than or equal to 0.8 as an example. The coaxiality of the valve core and the valve cavity is less than or equal to 3 mu m.
