[0002] At present, ball valves are widely used in oil refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries, and occupy a pivotal position in the national economy.

[0003] The utility model patent with patent publication number CN219082328U discloses a multi-directional controllable ball valve, which relates to the field of valve technology. The utility model includes a valve body, one end of which is fixedly connected to a flange; the other end of the valve body is fixedly connected to a valve seat; the valve seat sleeve is provided with a rotating rod; a telescopic rod is installed in a linear array around the rotating rod; a plurality of water outlet pipes are connected to the linear array around the valve body; a first pressing spring buckle is sleeved on the side of the valve body relative to the water outlet pipe; a plurality of ball seats are arranged in a linear array on the inner wall of the valve body; a valve ball is sleeved in the ball seat; a second pressing spring buckle is sleeved on the side around the valve ball. The utility model installs a plurality of valve balls in the valve body, and each valve ball and the side surface of the valve body are respectively provided with mutually cooperating pressing spring buckles. The rotating rod is used to drive the telescopic rod in the linear array around the rotating rod, which then cooperates with the pressing spring buckle to simultaneously control the rotation of a plurality of valve balls, thereby enabling diversion and closure at the same time, and is easy to operate.

[0004] However, in actual use, although the ball valve of this structure can synchronously control the diversion and closing, it cannot accurately control the size of the diversion, so that the medium flow cannot be accurately controlled, and it is not convenient to adjust the valve flow according to actual conditions. Therefore, a multi-directional controllable ball valve is proposed, which can accurately control the valve medium flow and improve the practicality of the ball valve. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a multi-directional controllable ball valve.

[0006] The utility model is realized through the following technical scheme: a multi-directional controllable ball valve, including a first tube shell and a second tube shell, the first tube shell and the second tube shell are connected to form a valve tube, a plurality of valve balls are cooperatively installed in the valve tube, a bolt rod is bolted in each of the valve balls, each of the bolt rods is commonly connected to an axle rod, one end of the axle rod is connected to a motor, the motor is electrically connected to an encoder, a plurality of water inlet pipes are welded to one side of the first tube shell, a plurality of water outlet pipes are welded to one side of the second tube shell, a flow meter is installed on each of the water outlet pipes, a plurality of the water inlet pipes are commonly connected to a connecting pipe, and a water injection port is provided on the connecting pipe.

[0007] It can be seen that in the above technical solution, by injecting the medium from the water inlet, the medium is divided from the connecting pipe into the water inlet pipe, and then enters the valve pipe, flows out from the water outlet pipe through the water holes opened inside each valve ball, and the medium flow rate discharged from the corresponding water outlet pipe is measured by each flow meter, and the rotation of the motor can be controlled by the encoder, which can make the shaft rotate, thereby making the valve ball rotate, so that the two sides of each water hole are synchronously changed with the flow path of the water inlet pipe and the water outlet pipe respectively, and cooperate with the detection of the flow meter to accurately control the flow of the discharged medium. At the same time, through the rotation of the motor, when each valve ball rotates 90°, the flow of the medium is closed.

[0008] Optionally, in a possible implementation manner, a water hole is opened in the middle of the valve ball, one end of the water hole is arranged in cooperation with the water inlet pipe, and the other end of the water hole is arranged in cooperation with the water outlet pipe.

[0009] It can be seen that in the above technical solution, after the corresponding medium enters from the water inlet pipe, it can enter the water hole, and then flow into the water outlet pipe from the other end of the water hole for discharge. The medium flow rate is controlled by the diameter size of the water hole connected with the water inlet pipe and the water outlet pipe.

[0010] Optionally, in a possible implementation, a through hole is formed through the valve ball, the through hole is vertically arranged to the water through hole, and a shaft rod is inserted through the through hole to be connected to each bolt rod.

[0011] It can be seen that in the above technical solution, each valve ball can be connected and fixed to the shaft rod by connecting the bolt rod and the shaft rod, so that during the rotation of the shaft rod, each valve ball can rotate synchronously, so that the connection diameter between the water hole opened in the valve ball and the inlet and outlet pipes can be adjusted, thereby regulating and controlling the medium flow.

[0012] Optionally, in a possible implementation, a cylindrical bolt groove is opened at one end of the valve ball, and a corresponding hexagonal limit groove is opened at the other end of the valve ball, a cylindrical hexagonal head is welded on the top end of the bolt rod, and the cylindrical hexagonal head is crimped in the cylindrical bolt groove, and a locking nut is sleeved on the bolt rod, and the locking nut is cooperatively arranged in the hexagonal limit groove.

[0013] It can be seen that in the above technical solution, the cylindrical hexagonal head at the top of the bolt rod is inserted into the cylindrical bolt groove, and the locking nut is arranged in the hexagonal limiting groove. When the cylindrical hexagonal head is screwed, the hexagonal limiting groove can limit the locking nut, thereby facilitating the installation of the bolt rod and making the bolt rod as a whole hidden in the valve ball, thereby preventing the installation of the bolt rod from affecting the rotation of the valve ball.

[0014] Optionally, in a possible implementation manner, shaft seals are installed in valve tubes between adjacent valve balls.

[0015] It can be seen that in the above technical solution, by installing a shaft seal in the valve tube between adjacent valve balls, the adjacent valve balls can be isolated to avoid mutual contamination when different media are injected.

[0016] The beneficial effects of the utility model are:

[0017] The utility model adopts the arrangement of a motor, an encoder and a plurality of valve balls connected to the shaft rod. Compared with the prior art, the utility model can accurately control the angle of rotation of the motor driven by the shaft rod when the motor is running by controlling the rotation of the motor through the encoder, thereby automatically adjusting the diameter of the medium connected to the water hole opened in the valve ball and the inlet and outlet pipes, thereby more accurately and synchronously controlling the medium flow, thereby improving the practicality of the ball valve.
