Description

Technical Field

[0001] The present invention relates to the technical field of agricultural valves, in particular to a partition control valve device for planting. Background Art

[0002] In actual vegetable planting, the growth of vegetables cannot be separated from water supply, especially in large-scale greenhouse planting. When the vegetable planting area involved is large, it is necessary to adjust the water volume according to the humidity requirements of different vegetable plots. The valve pipeline control structure plays an important role in actual vegetable planting, especially in off-season vegetable planting in winter greenhouses. The growth quality of vegetables is closely related to the water supply. The current zoning control valve is widely used due to its advantages such as flexible control. However, when the current planting zoning control valve is used in winter or in high-altitude cold areas, the water in the main pipeline stops flowing and is prone to freezing, causing pipeline rupture and affecting water supply. It is not convenient to automatically control the emptying of residual water. Pipes in low-lying areas are more likely to accumulate water. Irrigation water usually has more impurities, and the traditional filter structure is prone to clogging and requires frequent cleaning. At the same time, impurities such as sand and stones can easily cause the valve to get stuck, and long-term friction will easily cause water leakage, and the valve is not easy to automatically expand and close.

[0003] To this end, we propose a partition control valve device for planting. Summary of the Invention

After confirming that the expansion stopper 4 is in the state of being attached to the isolation ring 106, the antifreeze drainage part 6 is automatically controlled to discharge the residual water in the docking pipe 201, which can be more suitable for the water supply work of off-season vegetable greenhouses, and avoid the residual water in the docking pipe 201 outdoors from freezing after watering is completed, causing the docking pipe 201 to freeze and crack or affect the water supply. At the same time, this structure adopts a row of antifreeze connecting pipes 601 to discharge residual water, which can be suitable for low-lying terrain and other locations where residual water is easy to remain, and can ensure the antifreeze service life of the docking pipe 201. The method of discharging residual water also reduces the erosion of the pipeline caused by long-term water storage. At the same time, this structure adopts an electromagnet 602 to control the movement of the sliding sleeve 603, which can be automatically controlled without manual operation. It is more suitable for long-distance water delivery work and is more practical. Support rods 6041 can be used to support the ground, preventing the ground from affecting the movement of the sliding sleeve 603 and ensuring smooth control of the structure. Antifreeze connecting pipes 601 are fixed between the connecting pipes 201 by bolts. The number of antifreeze connecting pipes 601 can be adjusted according to the terrain. For example, in a depression, the antifreeze connecting pipes 601 are placed at the bottom of the depression. On some slopes, the number of antifreeze connecting pipes 601 can be reduced. The length of the connecting pipes 201 and the isolation filter plate 202 can be adjusted accordingly to ensure that the position of the antifreeze connecting pipes 601 can drain residual water. When the expansion stopper 4 moves forward to contact the isolation ring 106, it squeezes the sliding post 504. The sliding post 504 is compressed and retracts, squeezing the microswitch 502. The microswitch 502 then controls the electromagnet 602 to energize, and the magnetic ring 6031 controls the sliding sleeve 603 to move rightward. The sliding sleeve 603 no longer blocks the drainage hole 6011, allowing residual water to be drained.

[0039] The working principle of this embodiment is as follows: first, the water inlet pipe 104 is connected to the outlet pipe of a water source with a higher terrain, such as a reservoir, and the number of the connecting pipe 201 and the antifreeze connecting pipe 601 is set according to the needs, and the flanges are provided for docking. When docking, the adjacent isolation filter plates 202 are plugged into each other end to end through the docking groove blocks 2021 to limit the position, and the connecting pipe 201 is placed on the ground and laid to the water-using area. When the water is passed, the zoned drain valves 204 are controlled respectively to drain the water in the zone and irrigate. The zoned discharge pipe 203 is located above the isolation filter plate 202, and the water discharged by the main valve pipe 101 is isolated by the isolation plate 103. The isolation plate 103 is tilted upward to fit the drain pipe 102, and impurities are isolated at the bottom of the isolation plate 103 and filtered as the water flows through a row of isolation filter plates 202; when impurities need to be cleaned, the impurity discharge cock 702 is opened, and at this time, the zoned drain valves 204 are closed, and water is passed in the main valve pipe 101. The isolation filter plates 20 are isolated by the water flow. 2. The impurities at the bottom can be flushed out and discharged through the threaded holes on the blocking end plate 701; when the structure is controlled to stop water supply: rotating the mixing valve stem 301 drives the advancing piston 302 to move, pushing the expansion blocking column 401, and sealing it with the isolation ring 106 through the rubber sealing sleeve 403. If there is sand or stone or the rubber sealing sleeve 403 is worn to a certain extent, the mixing valve stem 301 is continued to be rotated, and the advancing piston 302 slides in the internal cavity of the expansion blocking column 401, compressing the return spring 404. At this time, the air pressure in the internal cavity of the expansion blocking column 401 increases, and the rubber sealing sleeve 403 is conducted through the exhaust hole 402. The middle section of the rubber sealing sleeve 403 expands and can be fully expanded to fit the isolation ring 106, preventing impurities such as sand and stone from affecting the sealing effect of the isolation ring 106. Reverse rotation of the mixing valve stem 301 can control the rubber sealing sleeve 403 to separate from the isolation ring 106. At this time, the water source can flow from the main valve pipe 101 to the drain pipe 102 for water supply;

[0040] When the expansion stopper 4 moves forward and fits the isolation ring 106, it will squeeze the sliding column 504. At this time, the sliding column 504 is compressed and retracts to squeeze the micro switch 502. At this time, the micro switch 502 can control the electromagnet 602 to be energized, and the magnetic iron ring 6031 controls the sliding sleeve 603 to move to the right. At this time, the sliding sleeve 603 no longer blocks the drainage hole 6011. Under the action of gravity, the water flow can be discharged from the drainage hole 6011. Correspondingly, when the expansion stopper 4 is controlled to move backward again to open the drainage, the expansion blocking column 401 no longer squeezes the micro switch 502, and the electromagnet 602 is powered off. Under the pull of the reset spring 605, the sliding sleeve 603 can be controlled to reset and block the drainage hole 6011, thereby ensuring normal water supply of this structure.
