Description

Technical Field

[0001] This utility model relates to a pipeline controller, specifically a dual pressure regulating pipeline controller. Background Technology

[0002] In current agriculture, spray trucks are commonly used for large-scale spraying operations on plants. These trucks mount sprayers on vehicles and use pipeline controllers to precisely control the spraying process. Pressure regulation is a crucial function of the pipeline controller in spraying operations, directly affecting the spraying effect, uniformity, and efficient resource utilization. However, most pipeline controllers on the market today have relatively simple pressure regulation designs, often employing only a single pressure regulating structure. This single structure has many limitations in practical applications and cannot meet the complex and ever-changing needs of spraying operations. For example, in different spraying scenarios, such as dealing with different plant species, different spraying distances, and different spray volume requirements, a single pressure regulating structure may not be able to flexibly and accurately adjust the pressure. Utility Model Content

[0003] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a dual pressure regulating pipeline controller.

[0004] One technical solution of this utility model is: a dual pressure regulating pipeline controller, which includes a pressure regulating valve, comprising a first main pipe and a second main pipe distributed and interconnected on the left and right. A guide tube that runs vertically through the first main pipe and communicates with the interior of the first main pipe is fixed at the lower end of the first main pipe. A first return water pipe that communicates with the guide tube is fixed at the lower end of the guide tube. A proportional valve is installed at the upper end of the first main pipe. A threaded sleeve that extends vertically is fixed at the upper end of the second main pipe. A valve core is installed inside the threaded sleeve. A pressure regulating nut is screwed onto the outside of the threaded sleeve. A spring that extends vertically is installed inside the threaded sleeve. The spring is locked between the upper end of the valve core and the inner wall of the upper end of the pressure regulating nut. A circular pipe that runs vertically through the second main pipe and communicates with the interior of the second main pipe is fixed inside the second main pipe. A sealing gasket located above the circular pipe is fixed at the lower end of the valve core. A second return water pipe that communicates with the circular pipe is fixed at the lower end of the second main pipe.

[0005] Furthermore, the proportional valve has a valve stem extending vertically, and a plug is fixed at the lower end of the valve stem for opening or closing the upper opening of the conduit, into which the conduit is inserted.

[0006] Furthermore, it also includes an outlet diversion valve, a flow meter, a filter, and a main valve, which are connected from left to right.

[0007] Furthermore, the first main pipe has a first channel for connecting the conduit, and the second main pipe has a second channel for connecting the circular pipe.

[0008] Furthermore, the valve core slides vertically against the inner wall of the threaded sleeve.

[0009] The advantages of using the dual pressure regulating pipeline controller provided by this utility model are: it has dual pressure regulating function, and the dual pressure regulating structures work together to make pressure regulation more flexible and precise. Attached Figure Description

Detailed Implementation

[0013] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0014] like Figure 1 , Figure 2 As shown, a dual pressure regulating pipeline controller includes a pressure regulating valve 1. The pressure regulating valve 1 includes a first main pipe 1.1 and a second main pipe 1.2 that are distributed left and right and interconnected. A conduit 2 that runs vertically through the lower end of the first main pipe 1.1 and communicates with the interior of the first main pipe 1.1 is fixed. A first return water pipe 3 that communicates with the conduit 2 is fixed at the lower end of the conduit 2. A proportional valve 4 is installed at the upper end of the first main pipe 1.1. A threaded sleeve 5 that extends vertically is fixed at the upper end of the second main pipe 1.2. A valve core 6 is installed inside the threaded sleeve 5. A pressure regulating nut 7 is screwed onto the outside of the threaded sleeve 5. A spring 8 that extends vertically is installed inside the threaded sleeve 5. The spring 8 is locked between the upper end of the valve core 6 and the inner wall of the upper end of the pressure regulating nut 7. A circular pipe 9 that runs vertically through the second main pipe 1.2 and communicates with the interior of the second main pipe 1.2 is fixed inside. A sealing gasket 10 located above the circular pipe 9 and used to open or close the opening at the upper end of the circular pipe 9 is fixed at the lower end of the valve core 6. A second return water pipe 11 that communicates with the circular pipe 9 is fixed at the lower end of the second main pipe 1.2.

[0015] like Figure 2As shown, the proportional valve 4 has a valve stem 41 extending vertically. A plug 42 is fixed to the lower end of the valve stem 41 for opening or closing the upper opening of the conduit 2, into which the plug 42 extends. The valve stem 41 drives the plug 42 to move vertically, adjusting the degree to which the upper opening of the conduit 2 is opened, thereby adjusting the return water pressure. When the upper end of the conduit 2 is opened, water in the first main pipe 1.1 flows into the conduit 2 through the gap between the plug 42 and the conduit 2, and flows out from the first return water pipe 3.

[0016] The dual pressure regulating pipeline controller also includes an outlet diversion valve 12, a flow meter 13, a filter 14, and a main valve 15, which are connected from left to right.

[0017] like Figure 2 As shown, the first main pipe 1.1 has a first channel 1.1.1 for connecting to the conduit 2, and the second main pipe 1.2 has a second channel 1.2.1 for connecting to the circular pipe 9.

[0018] like Figure 2 As shown, the valve core 6 slides vertically against the inner wall of the threaded sleeve 5. Rotating the pressure adjusting nut 7 adjusts the tension of the spring 8, thereby regulating the pressure required to open the valve core 6. Rotating the pressure adjusting nut 7 downwards reduces the opening between the lower end of the sealing gasket 10 and the upper end of the round tube 9, and vice versa. During operation, if the pressure inside the second main pipe 1.2 is too high, the pressure adjusting nut 7 can be loosened to increase the opening between the lower end of the sealing gasket 10 and the upper end of the round tube 9.

[0019] The dual pressure regulating pipeline controller provided by this utility model has dual pressure regulating functions. The proportional valve 4 can be finely adjusted, and the pressure regulating nut 7 can be coarsely adjusted. The dual pressure regulating structures work together to make pressure regulation more flexible and precise.

[0020] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
