Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fluid control, particularly to a valve design capable of adjusting flow path direction and having cleaning function. BACKGROUND

[0002] In modern industrial and agricultural automation, valves as a key pipe accessory are widely used to control the flow direction and flow rate of fluids. In particular, in the field of animal breeding, valves are used in water feeding pipelines to control the flow direction of nutrient solution or water, so as to meet the water feeding needs of different breeding areas. For example, in an automated breeding system, the valve needs to be able to flexibly switch the flow path to achieve precise water or nutrient solution feeding to different areas.

[0003] In addition, valves also play an important role in protecting wild animals. In wildlife protection areas or zoos, valves are used to manage the fluid control of artificial lakes, water feeding points and feeding systems. For example, by precisely controlling the flow direction and flow rate of fluids, it can ensure that wild animals obtain appropriate amount of water and nutrient solution in different seasons and different areas. This precise control not only helps the health of animals, but also reduces resource waste and improves management efficiency.

[0004] However, the existing multi-path control valve has some shortcomings in practical application, especially in the scenes of animal water feeding or protecting wild animals. For example, Chinese patent CN201920292798 (a multi-path control valve) uses a rotating valve plug to switch the flow path between the input end and the two output ends, but has the following limitations:

[0005] 1. The multi-path control valve mainly uses a rotating valve plug to switch the flow path between the input end and the two output ends, but cannot realize more complex flow path control, such as arbitrary connection or disconnection between three main flow paths. In the scene of animal water feeding, it may be necessary to control the delivery of nutrient solution, water and medicine at the same time, and the existing design cannot meet such complex needs.

[0006] 2. The multi-path control valve does not have a special cleaning function, and cannot clean the inside of the valve when switching the flow path. In the scene of animal water feeding, the residual nutrient solution or medicine inside the valve may breed bacteria, causing fluid pollution and affecting animal health.

[0007] 3. Although the multi-path control valve in the prior art mentions a sealing gasket, there may still be a problem of poor sealing during complex flow path switching, leading to fluid leakage. In the scene of animal water feeding, the leaked fluid may pollute the breeding environment and increase maintenance costs.

[0008] 4. Multi-channel control valves cannot completely isolate flow paths when switching flow paths, which may cause cross-contamination between fluids. In the animal watering scenario, if it is necessary to deliver nutrient solution first and then deliver drug solution, the residual nutrient solution may contaminate the drug solution, affecting the drug effect.

[0009] 5. Multi-channel control valves can only control three channels and cannot achieve flexible control of more channels. In a complex animal watering system, more flow paths may be needed to meet different needs. Utility model content

[0015] Further, the valve capable of adjusting the flow path direction and having the cleaning function comprises a valve seat plug 7 for closing the fifth passage 501.

[0016] Further, the rotation of the valve core 4 can align the first sector hole with the first passage and the third passage, so as to realize the communication of the flow path between the first passage and the third passage.

[0017] Further, the rotation of the valve core can isolate the first sector hole and the second sector hole from the first passage and the third passage, while making the fourth passage and the fifth passage communicate, so as to realize the cleaning function inside the valve.

[0018] In addition, by rotating the valve core piece, the valve can realize the communication of any two flow paths of the three main flow paths or the mutual communication of all flow paths, and can realize the isolation of the three main flow paths and the on-off of the flow path between the fourth passage and the fifth passage.

[0022] Compared with the prior art, the valve has the following beneficial effects:

[0023] Functional diversification and cleaning performance improvement The present application constructs a complete flow path system including three main flow paths (first passage, second passage, third passage) and fourth passage and fifth passage through scientific and reasonable valve core design and flow path layout. Through the rotation of the valve core, not only the communication or all communication between any two of the three main flow paths can be realized, but also the cleaning function inside the valve can be realized through the communication of the fourth passage and the fifth passage.

At the same time, the valve core surface is provided with a sealing ring installation groove, the valve body and the valve seat are connected by bolts and provided with a sealing groove to accommodate the sealing ring, further enhancing the sealing performance of the valve, reducing the risk of fluid leakage, and ensuring the safety and reliability of the system.
