[0027] Reference Figure 1-Figure 4 The utility model provides a farm irrigation water supply valve, comprising a valve body 1, a screw rod 2 and a valve plate 3. The valve body 1 is provided with two openings, which are divided into a water outlet 4 and a water inlet 5. Figure 4, the valve plate 3 is arranged in the valve body 1, the screw rod 2 is threadedly connected with the valve body 1, and the bottom of the screw rod 2 passes through the valve body 1 and is connected to the valve plate 3, the valve plate 3 can reach the water inlet 5 to close the water, and a rubber sealing pad 8 is arranged at the bottom of the valve plate 3 to improve the sealing performance of the valve plate 3. A bare rod section 201 is arranged in the middle of the screw rod 2, and the top and bottom of the screw rod 2 can be threadedly matched with the valve body 1. When the screw rod 2 is rotated to reach the bare rod section 201, the screw rod 2 can be slid up and down due to the lack of thread restriction, which can effectively save the time of rotating the screw rod 2. However, in actual use, the water supply valve needs to be kept fully opened or closed to prevent water from flowing out between the bare rod section 201 of the screw rod 2 and the valve body 1. A rubber sealing pad 8 is arranged at the bottom of the screw rod 2, which is clamped between the screw rod 2 and the valve body 1 when the water supply valve is fully opened to prevent water from leaking from the connection and play a sealing role. A handle 10 is arranged at the top of the screw rod 2 to help twist the screw rod 2.

[0028] The valve body 1 is made of environmentally friendly recycled PCABS alloy material, which has the advantages of anti-aging, corrosion resistance, radiation resistance, acid and alkali resistance, long service life, etc. The valve body 1 includes an upper valve body 101 and a lower valve body 102 connected by threads, and the threaded connection is very convenient for disassembly and maintenance.

[0029] An upper flange 6 is provided at the bottom of the upper valve body 101, and a lower flange 7 is provided at the top of the lower valve body 102. The upper and lower valve bodies are fixed by connecting with stainless steel screws 9 through the flanges to prevent loosening and rusting. A downwardly extending flange 601 is provided on the outer circumference of the upper flange 6. When the upper valve body 101 and the lower valve body 102 are threadedly connected, the flange 601 can wrap the lower flange 7. Only the upper flange 6 and the flange 601 can be seen from the outside, preventing damage caused by the intrusion of foreign objects such as dust. A rubber sealing gasket 8 is provided between the upper flange 6 and the lower flange 7. The rubber sealing gasket 8 is blocked by the flange 601 and is not exposed, which can prevent the rubber from aging prematurely and increase the service life.

[0030] Here’s how it works:

[0031] When the valve needs to be opened, use the handle 10 to turn the screw 2 counterclockwise to rotate it to move the screw 2 upward. When the thread at the top of the screw 2 separates from the valve body 1, it reaches the bare rod section 201 of the screw 2. At this time, the screw 2 is no longer threadedly connected to the valve body 1. Then quickly slide the screw 2 upward to reconnect the thread at the bottom of the screw 2 to the valve body 1. Finally, the valve plate 3 is fully opened and the water supply valve starts to work.

[0032] When the valve needs to be closed, the screw rod 2 is turned clockwise to reconnect the thread on the top of the screw rod 2 to the valve body 1, and the valve plate 3 reaches the water inlet 5 of the lower valve body 102 to shut off the water, and the water supply valve is shut off and stops working.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
