Description

Technical Field

[0001] The utility model relates to the technical field of agricultural irrigation devices, in particular to an irrigation water pipe. Background Art

[0002] With the promotion of efficient water-saving irrigation technology, the area of pipe irrigation in southern paddy fields has increased rapidly. However, the flow rate of the water outlet of the water hydrant is too fast. The flow rate of the existing low-pressure pipeline field water hydrant that needs to dissipate energy is generally 1-2m / s. The outlet diameter of the water hydrant is commonly used to be 75mm, 90mm, and 110mm. The ideal energy dissipation effect is to reduce its flow rate to 0.2-0.3m / s. The outlet pipe of the existing water hydrant is a straight pipe. The high flow rate causes a large impact surface at the outlet, which can easily cause a huge impact on crops, resulting in damage and death of crops.

[0003] For this purpose, we propose an irrigation water pipe. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides an irrigation water pipe.

[0005] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present utility model is:

[0006] An irrigation water pipe comprises: a connecting section connected to the water outlet of a water tap via a flange; an expanded diameter section having an inner diameter larger than that of the connecting section, wherein the water inlet end of the expanded diameter section is connected to the water outlet end of the connecting section via a connecting ring.

[0007] By setting an expanded diameter section connected to the connecting section, the expanded diameter section can form a negative pressure at the connecting ring and generate a vortex, thereby dissipating energy of the water coming out of the connecting section. The expanded diameter section can guide the water flow and reduce the flow rate of the water flow, thereby avoiding the water outlet from having too much impact on the pile of crops and causing impact damage.

[0008] The invention is further defined as including an adjusting hole, the adjusting hole being opened at the top of the expanded diameter section, and the adjusting hole (4) being opened at the water inlet end close to the expanded diameter section (2), a sealing cylinder being vertically provided at the position of the adjusting hole, the sealing cylinder being fixedly connected to the pipe wall of the expanded diameter section, and a sealing plug being provided in the sealing cylinder for sealing the adjusting hole; by providing an adjusting hole, and sealing the adjusting hole through the sealing plug when it is necessary to dissipate energy of the water flow, in some cases where the water pressure is low or the water flow velocity does not need to be reduced, the sealing plug can be opened to allow the water flow of the expanded diameter section to contact with the air, thereby eliminating the internal negative pressure, and the water flow from the water tap forms a free outflow, does not dissipate energy, does not reduce the flow velocity, and ensures the irrigation flow.

[0009] It is further defined that the sealing plug is threadedly connected to the sealing cylinder. When the sealing plug is fully screwed in, the bottom surface of the sealing plug is flush with the inner wall of the expanded diameter section, and the bottom surface of the sealing plug matches the inner wall surface of the expanded diameter section. The sealing plug is T-shaped and includes an upper limiting portion and a lower sealing portion. The bottom surface of the limiting portion and the bottom surface of the sealing cylinder are respectively provided with a first sealing groove, and a first sealing ring is embedded in the first sealing groove; a first sealing groove is provided on the limiting portion of the sealing plug and the top surface of the sealing cylinder and a first sealing ring is embedded. When the sealing plug is tightened in the sealing cylinder by threads, the first sealing groove and the first sealing ring are clamped and sealed to improve the sealing performance. The bottom surface of the sealing plug is an arc surface that matches the inner wall surface of the expanded diameter section, which can greatly reduce the impact on water flow in a sealed state.

[0010] It is further defined that a plurality of mounting holes are arranged around the end face of the flange, and each mounting hole is a strip-shaped hole; setting the mounting holes on the end face of the flange as strip-shaped holes facilitates personnel to fine-tune the flange during installation, making installation easier.

[0011] It is further defined that a second sealing groove is circumferentially opened on the end face of the flange, a second sealing ring is embedded in the second sealing groove, and the cross-sections of the second sealing groove and the second sealing ring are both rectangular; a second sealing groove is opened on the end face of the flange, and a second sealing ring is arranged in the second sealing groove. When the flange and the mounting flange of the water faucet are tightly connected, the second sealing ring will be deformed, which can also further improve the sealing performance.

[0012] It is further defined that a connecting groove is provided in an annular direction on the water outlet of the flange end face, and a connecting ring is removably provided in the connecting groove; by providing a connecting groove on the water outlet of the flange end face, it can be installed on the mounting flange of a water faucet with a connecting protrusion, and providing a removable connecting ring allows the flange to also be installed on the mounting flange of a water faucet with a connecting groove, which has a wider installation adaptability.

[0013] The beneficial effects of the utility model are as follows: by connecting an expanded diameter section to the connecting section, the water flowing out of the water tap can be dissipated, so that its flow rate is reduced, thereby avoiding damage to crops caused by excessive flow rate; and the utility model has good sealing, is not easy to leak, and has a simple structure.
