[0056] The working principle of the utility model is:

[0057] 1), water flow control mechanism:

[0058] The core component of the water supply tap is the butterfly valve switch, which is composed of the switch valve body 1, the valve seat 3 and the valve plate 4. When the user needs to adjust or close the water flow, the angle position of the valve plate 4 can be changed by rotating the shaft 5 connected to the valve plate 4.

[0059] The valve seat 3 is installed in the switch valve body 1, and the position is fixed by clamping the protrusion 12 in the switch valve body 1, which ensures the sealing and stability.

[0060] The valve plate 4 is rotatably installed on the valve seat 3 through the shaft 5, and the both ends of the shaft 5 extend to the outside of the switch valve body 1, which is convenient for the user to operate;When the valve plate 4 is in a horizontal state, the water flow is completely blocked;When the valve plate 4 is gradually rotated to the vertical direction, the water flow passage is opened, allowing the water flow to pass.

[0061] 2), quick change connector function:

[0062] In order to realize the quick switching between different types of irrigation tools or systems, the water supply tap is designed with three kinds of quick change connector assemblies: bayonet joint 9, quick connector 10 and fire hydrant 11.

[0063] One end of the pipe assembly (which can be an elbow 7 or a straight-through 8) is installed in cooperation with the upper end face of the switch valve body 1, and is clamped from the outside by the gland 2, which ensures that the connection is tight and stable.

[0064] The other end of the pipe assembly is screwed with the corresponding quick-change connector, allowing users to easily change the type of connector without tools, improving the flexibility and efficiency of irrigation operations.

[0065] 3) Dustproof protection measures:

[0066] A dust screen 6 is installed at the end of the pipe assembly, effectively preventing dust and other impurities from entering the water faucet, keeping the equipment clean, reducing the risk of failure caused by foreign matter, and prolonging the service life.

[0067] 4) Overall operation process:

[0068] When starting the irrigation operation, the user first installs the required type of quick-change connector on the water faucet, and then adjusts the valve plate 4 angle by rotating the shaft 5 to open or adjust the water flow size.

[0069] During irrigation, the dust screen 6 acts as a barrier to prevent external pollutants from entering; after irrigation is completed, the user can quickly replace other types of connectors to adapt to new irrigation tasks, or completely close the butterfly valve switch to stop water supply.
