[0021] The inner wall of the valve body 3 is fixedly connected to the outer wall of the flow component 4. The flow component 4 includes a barrier block 401 and a valve core 402. A first flow cavity is formed in the inner wall of the barrier block 401 near one side. Second and third flow cavities are respectively formed in the inner walls of the barrier block 401 near the back and the front. The inner wall at the center of the barrier block 401 is rotatably connected to the outer wall of the valve core 402. A flow groove is formed in the inner wall of the valve core 402, and the cross-sectional shape of the flow groove is set as an L shape. The outer wall at the top of the flow component 4 is fixedly welded to the bottom end of the adjusting component 5, and the outer wall of the adjusting component 5 is rotatably connected to the inner wall of the valve body 3.

[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the input component 1 is composed of an input pipe 101, a support frame 102 and a connecting pipe 103. The inner wall of the input pipe 101 is fixedly welded to the outer wall of the support frame 102. The bottom end of the input pipe 101 is fixedly connected to one end of the connecting pipe 103. A groove is formed in the inner side wall of the input pipe 101. When materials need to be input, the materials enter through the input pipe 101.

[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the metering component 2 includes a support column 201, a spring 202, a sliding column 203 and a sliding block 204. The inner bottom wall of the support column 201 is fixedly connected to the bottom end of the spring 202. The top end of the spring 202 is fixedly connected to the bottom end of the sliding column 203. The outer side wall of the sliding column 203 is slidably connected to the inner side wall of the support column 201. The top end of the sliding column 203 is fixedly connected to the bottom of the sliding block 204. The bottom end of the support column 201 is fixedly connected to the top of the support frame 102.

When the materials start to flow into the input pipe 101, as the amount of materials accumulates, the sliding block 204 moves downward under the pressure of the materials, compressing the spring 202. This process can be controlled by the preset stiffness of the spring 202. When the compression amount reaches a certain threshold, the sliding block 204 slides into the groove.

[0025] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer wall of the barrier block 401 is fixedly connected to the inner wall of the three-way valve body 301. When the valve core 402 rotates inside the barrier block 401, the L-shaped flow groove will be connected or staggered with different flow cavities on the barrier block 401, thereby controlling the flow path of the fluid.

[0026] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjusting member 5 is composed of a connecting rod 501, an adjusting disk 502, a latch 503 and a toggle block 504, and the top of the connecting rod 501 is fixedly connected to the bottom of the adjusting disk 502, the inner wall of the adjusting disk 502 is movably plugged with the outer wall of the latch 503 near the top, and the top of the latch 503 is fixedly connected to the bottom of the toggle block 504, the outer wall of the latch 503 near the bottom is movably plugged with the inner wall of the first locking groove, and the outer wall of the connecting rod 501 is rotatably connected with the inner wall of the rotating groove, and the bottom end of the connecting rod 501 is fixedly welded to the outer wall of the top of the valve core 402. When the valve is closed, the latch 503 is located in the second locking groove. When the flow path of the fluid needs to be adjusted, the latch 503 is pulled out by the toggle block 504. 3. Rotate the adjusting disk 502 to drive the valve core 402 to rotate in the blocking block 401, so that the flow groove of the valve core 402 is aligned with the first flow cavity and the second flow cavity at the same time, and the fluid can flow from the first flow cavity through the flow groove into the second flow cavity to realize fluid exchange between the two directions. After adjustment, insert the pin 503 into the first locking groove for locking. When the flow path of the fluid needs to be changed, rotate the adjusting disk 502 again to drive the valve core 402 to rotate in the blocking block 401, so that the flow groove of the valve core 402 is aligned with the first flow cavity and the third flow cavity at the same time, and the fluid can flow from the first flow cavity through the flow groove into the second flow cavity, so as to conveniently realize the switching of pipelines and meet different fluid transportation requirements.

[0027] The use method and advantages of the utility model: When the device which is convenient for switching pipelines and quantitative input is working, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the valve is closed, the latch 503 is located in the second locking groove. When the flow path of the fluid needs to be adjusted, the latch 503 is pulled out by the toggle block 504, and the adjusting disk 502 is rotated to drive the valve core 402 to rotate in the blocking block 401, so that the flow groove of the valve core 402 is aligned with the first flow cavity and the second flow cavity at the same time, and the fluid can flow from the first flow cavity through the flow groove into the second flow cavity to achieve fluid exchange between the two directions. After adjustment, the latch 503 is inserted into the first locking groove for locking. When the flow path of the fluid needs to be changed, the adjusting disk 502 is rotated to drive the valve core 402 to rotate in the blocking block 401, so that the flow groove of the valve core 402 is aligned with the first flow cavity and the third flow cavity at the same time. The fluid can flow from the first circulation cavity through the circulation groove into the second circulation cavity, which facilitates the switching of the pipeline. When the material begins to flow into the input pipe 101, as the amount of material accumulates, the sliding block 204 moves downward under the pressure of the material, compressing the spring 202. This process can be controlled by the pre-set stiffness of the spring 202. When the compression reaches a certain threshold, the sliding block 204 slides into the groove. At this time, the material flows from the groove to the bottom. After the quantitative material flows in, the pressure on the spring 202 decreases, and the spring 202 begins to release the stored elastic potential energy, pushing the sliding column 203 and the sliding block 204 to move upward and return to the initial position or a preset position, thereby realizing quantitative control of the material input amount.
