Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment technology, and in particular to an irrigation outlet pipe. Background Technology

[0002] Buried sprinklers are sprinklers that are directly buried underground. They are hidden below the ground during non-irrigation periods and are mainly used for green space irrigation and irrigation of some cash crops. They are characterized by a long service life and do not interfere with surface field operations. The sprinklers are completely buried underground. During irrigation, water pressure causes the sprinklers to extend above the ground or crop surface to spray water. After irrigation, the sprinklers retract below the ground under gravity due to the absence of water pressure, making the irrigation equipment well-concealed.

[0003] While the irrigation pipes used in buried sprinklers can perform irrigation operations, it is difficult to ensure a stable water delivery when the water pressure is unstable, which affects the irrigation work. Utility Model Content

[0004] This utility model provides an irrigation outlet pipe that can control and adjust irrigation and drainage operations, ensuring stable irrigation. When irrigation stops, it can also quickly release the pressure on the adjusting head, causing the second sealing ring to block the gap between the adjusting seat and the lifting seat. It is simple and convenient to operate and provides stable water supply.

[0005] To solve the above-mentioned technical problems, this utility model provides an irrigation outlet pipe, comprising:

[0006] The outer tube has a positioning head at one of its top ends, and a positioning seat is fixedly installed inside the positioning head.

[0007] The inner tube is movably disposed inside the outer tube;

[0008] A lifting seat is disposed at the bottom of the inner wall of the inner tube, and the diameter of the lifting seat is smaller than the diameter of the positioning seat;

[0009] An adjusting head is provided with a second sealing ring. The adjusting head is movably disposed inside the lifting seat, and the diameter of the second sealing ring is not less than the diameter of the lifting seat.

[0010] As a preferred embodiment of the above technical solution, the positioning head is provided with a slot inside, the positioning seat is provided with a positioning disk and the positioning disk is located inside the slot, and the outer wall of the positioning seat is surrounded by a first sealing ring.

[0011] As a preferred embodiment of the above technical solution, the inner tube is slidably connected to the inner wall of the outer tube, and the inner tube is located at the bottom of the positioning seat when it moves to the highest position.

[0012] As a preferred embodiment of the above technical solution, the inner wall of the lifting seat is provided with a support seat, and the surface of the support seat is provided with a compression spring.

[0013] As a preferred embodiment of the above technical solution, the top end of the inner tube is threaded with an elbow, the top of the elbow is provided with a valve, and the valve is provided with a valve stem.

[0014] As a preferred embodiment of the above technical solution, the top of the adjusting head is provided with a mounting seat, and one end of the bottom of the valve stem is threadedly connected to the mounting seat.

[0015] As a preferred embodiment of the above technical solution, a filter cap is threaded at one end of the top of the inner tube, and a filter screen is provided inside the filter cap and extends into the inner tube.

[0016] This utility model provides an irrigation outlet pipe, which has an outer pipe, an inner pipe, a lifting seat, and an adjusting head. When irrigation is needed, water is introduced from the bottom of the outer pipe, and the water pushes the inner pipe and the lifting seat upward. When the inner pipe moves to the bottom of the positioning seat and can no longer move upward, the valve rod at the top adjusts the adjusting seat downward, leaving a gap between the adjusting seat and the lifting seat for water to be transported upward. After the water is transported upward through the inner pipe, it is drained outward through the elbow for irrigation or automatically drained outward through the filter cap. The entire device can controllably and adjustably carry out irrigation and drainage work, ensuring stable irrigation. When irrigation stops, the pressure on the adjusting head can be quickly released, and the second sealing ring can block the gap between the adjusting seat and the lifting seat. The operation is simple and convenient, and the water supply is stable.

[0028] The adjusting head 7 is provided with a second sealing ring 71. The adjusting head 7 is movably disposed inside the lifting seat 5, and the diameter of the second sealing ring 71 is not less than the diameter of the lifting seat 5.

[0029] This embodiment provides an irrigation outlet pipe, which has an outer pipe 1, an inner pipe 2, a lifting seat 5, and an adjusting head 7. When irrigation is needed, water is introduced from the bottom of the outer pipe 1, and the water pushes the inner pipe 2 and the lifting seat 5 upward. When the inner pipe 2 moves to the bottom of the positioning seat 4 and can no longer move upward, the valve rod 31 of the valve 3 above adjusts the valve to drive the adjusting seat 7 downward, leaving a gap between the adjusting seat 7 and the lifting seat 5 for water to be transported upward. After the water is transmitted upward through the inner pipe 2, it is drained outward through the elbow 8 for irrigation or automatically drained outward through the filter cap 9. The entire device can controllably and adjustably carry out irrigation and drainage work, ensuring the stable operation of irrigation. When irrigation stops, the pressure on the adjusting head 7 can be quickly removed, and the second sealing ring 71 can block the gap between the adjusting seat 7 and the lifting seat 5.
