Description

Technical Field

[0001] The utility model relates to the technical field of intelligent irrigation, in particular to an intelligent irrigation control valve. Background Art

[0002] In the process of planting in large-scale farmland, intelligent irrigation is needed to solve the water supply needs of large-scale farmland. Multiple branch water supply pipes are connected by the main water supply pipe on the outside of the intelligent irrigation system. The branch water pipes enter the farmland area, and valves are set in each branch water supply pipe to control the irrigation area.

[0003] Usually one or two water pumps are installed in the irrigation system to meet the irrigation water needs. The water pump draws water directly from the water reservoir and transports it to the main water supply pipe. In this process, in order to prevent stains and impurities in the water reservoir from entering the water pump and causing damage to the inside of the water pump, a filter device is installed in the pipeline on the side close to the water pump. However, in actual use, when the filter device has been working for a certain period of time and too many impurities accumulate inside, the operator is required to disassemble the pipeline to replace the filter material, otherwise it will affect the normal operation of the water pump.

At this time, the drainage valve is closed and the water delivery valve is opened. The water contacts the filter material in the mounting frame in the output pipe and penetrates the filter material. The filter material blocks the impurities in the water flow, and because of its own shape and the scouring of the water flow, the impurities intercepted by the filter material will move toward the center position, so that the surface of the filter material will not be completely covered by the impurities to ensure the filtering effect. When the impurities in the filter material reach the upper limit, the water pump is started to reverse. At this time, the water flows along the output pipe to the input pipe side and enters, taking the impurities on the surface of the filter material away from the filter material and entraining the impurities into the water distribution pipe. At this time, the check valve is closed, and the water flows outward along the drainage valve to take out the impurities. The filter material can be cleaned without disassembling the pipeline.

[0019] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0020] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0021] Example 1

[0022] like Figure 1-3 As shown, an intelligent irrigation control valve comprises an input pipe 1, wherein one end of the input pipe 1 is provided with a water delivery valve 2, and the output end of the water delivery valve 2 is provided with an output pipe 3, wherein the input pipe 1 and the output pipe 3 are respectively arranged on both sides of the water delivery valve 2, and an installation frame 4 is arranged on the inner wall of the output pipe 3, and a filter material 5 is arranged on the surface of the installation frame 4, wherein the installation frame 4 is composed of mesh plates on both sides and a center rod between the mesh plates, and the filter material 5 is arranged on the outside of the center rod, and the filter material 5 is a conical sheet structure, and a total of a plurality of the filter materials 5 are arranged horizontally. The filter materials 5 are evenly arranged, and there is a gap between each filter material 5, and the opening direction of the filter material 5 is toward the water distribution pipe 6. A water distribution pipe 6 is arranged on the side of the output pipe 3 away from the water delivery valve 2, and a check valve 7 and a drain valve 8 are installed inside the water distribution pipe 6. The water distribution pipe 6 is a Y-shaped three-way pipe, wherein the horizontal part of the pipeline is respectively connected to the output pipe 3 and the check valve 7, and the vertical part of the pipeline is provided with a drain valve 8. The check valve 7 and the drain valve 8 are both electrically controlled remote valves, and the check valve 7 and the drain valve 8 are electrically connected.

[0023] Working principle: First, the water pump drives the water flow through the check valve 7 and into the water distribution pipe 6. At this time, the drainage valve 8 is closed and the water flows along the water distribution pipe 6 into the output pipe 3 and passes through the filter material 5. The filter material 5 filters the impurities in the water flow. Due to its own shape and the water flow, the impurities on the surface of the filter material 5 will move to the center, so that its surface will not be completely covered by impurities. Then the water flows through the water delivery valve 2 and the input pipe 1 into the irrigation system;

[0024] When the impurities in the filter material 5 reach the upper limit, the working direction of the water pump can be reversed, so that the water flows along the input pipe 1 to the output pipe 3 and passes through the filter material 5. At this time, the water flow is filtered by the filter material 5, so no impurities will be left on the surface of the filter material 5. At the same time, the water flow passing through the filter material 5 will carry the impurities on the other side away from the filter material 5. The water flow cannot flow through the check valve 7 and can only flow outward through the drain valve 8 to bring the impurities out of the pipeline.

[0025] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
