Description

Technical Field

[0001] The utility model relates to the field of agricultural spray nozzles, in particular to an anti-overflow one-way nozzle. Background Art

[0002] The sprinkler is the most important part of the sprinkler system. Pressurized water is sprayed into the air through it, and then dispersed into fine water droplets and evenly scattered on the spray area it controls. It is also called a sprinkler. Its function is to convert the pressure energy of the water flow into kinetic energy, spray it into the air to form raindrops, and evenly distribute them to the spray area to spray the lawn. The sprinkler can be installed on a fixed or mobile pipeline, on the water pipe of the sprayer group truss, and on the traction frame of the winch sprinkler, and it can form a complete sprinkler or sprinkler system with matching machines and pumps. The performance of the sprinkler and whether it is used properly will play a decisive role in the spraying quality, economy and working reliability of the entire sprinkler system or sprinkler.

[0003] Existing sprinkler heads are directly connected to the water supply pipe. Although the water spraying speed is fast and smooth, after the water spraying stops, a large amount of water remains in the water supply pipe, so the sprinkler heads will still flow water after the water spraying stops. In the scene of large-scale mechanized spraying, the amount of water used for spraying cannot be accurately controlled, and unnecessary waste of water resources will occur, resulting in poor spraying effect and high spraying cost.

[0025] The nozzle body 11 has a buffer chamber 14, the lower surface of the buffer chamber 14 is fixedly connected to a guide platform 15, and the guide platform 15 has a guide pipe 16. The guide platform 15 and the buffer chamber 14 can ensure the water pressure on the one hand, and better cooperate with the anti-overflow component 2 on the other hand.

[0026] A water outlet pipe 17 is provided on one side of the nozzle body 11 close to the nozzle assembly 3, and the water outlet pipe 17 is connected to the flow guide pipe 16. A water inlet pipe 13 is provided in the extended water inlet head 12, and the water inlet pipe 13 is connected to the buffer chamber 14. Water flows into the buffer chamber 14 through the water inlet pipe 13, then into the flow guide pipe 16 through the buffer chamber 14, and then into the water outlet pipe 17 through the flow guide pipe 16. The extended water inlet head 12 is not vertically arranged with the plane of the fixed outer tube connecting frame 4, and the water inlet pipe 13 is arranged parallel to the nozzle assembly 3.

[0027] The anti-overflow assembly 2 includes an anti-overflow body 21, an air vent 22 is provided on the upper surface of the anti-overflow body 21, the anti-overflow body 21 is threadedly connected to the side outlet connection thread 18, and a sealing ring 28 is connected between the anti-overflow body 21 and the side outlet connection thread 18. The sealing ring 28 can effectively ensure the sealing of the anti-overflow body 21, and the consistency of the atmospheric pressure can be ensured by the air vent 22, so that the anti-overflow effect can be achieved normally.

[0028] The anti-overflow body 21 is fixedly connected with a limited sliding sleeve 23 inside, and the limited sliding sleeve 23 is slidably connected with a limited sliding column 24 inside. One end of the limited sliding column 24 is fixedly connected with a connecting slider 26, and the lower surface of the connecting slider 26 is fixedly connected with an anti-overflow diaphragm 27, and the anti-overflow diaphragm 27 is cooperatively connected with the guide platform 15. The connecting slider 26 moves up and down with the limited sliding column 24, thereby driving the anti-overflow diaphragm 27 to move up and down, or making the anti-overflow diaphragm 27 contact with the guide platform 15, so as to achieve a sealing effect.

[0029] A return spring 25 is sleeved on the outer side of the limiting sliding sleeve 23, one end of the return spring 25 is fixedly connected to the inner upper surface of the anti-overflow body 21, and the other end of the return spring 25 is fixedly connected to the upper surface of the connecting slider 26. The return spring 25 can ensure that the anti-overflow diaphragm 27 can press against the guide platform 15 when the water pressure is insufficient, thereby achieving the anti-overflow effect.

[0030] The nozzle assembly 3 includes a water outlet nozzle 31, one end of which is fixedly connected to a limit retaining ring 32, and a filter 33 is fixedly connected to one side surface of the limit retaining ring 32. The filter 33 can effectively filter impurities in the water to prevent the impurities in the water from clogging the water spray pipe 35, thereby ensuring the normal operation of the water outlet nozzle 31.

[0031] A pressurizing sleeve 34 is fixedly connected between the water outlet nozzle 31 and the limit retaining ring 32, and a water spray pipe 35 is provided on the water outlet nozzle 31, and the water spray pipe 35 is connected to the pressurizing sleeve 34. A diffuser 36 is provided at the end of the water outlet nozzle 31, and the diffuser 36 is connected to the water spray pipe 35. The pressurizing sleeve 34 can increase the water pressure, thereby increasing the flow rate of water in the water spray pipe 35, and the diffuser 36 can expand the area of ​​the water spray, thereby ensuring the efficiency of the spray.

[0032] The outer side of the water outlet nozzle 31 is sleeved with a nozzle connecting nut 37, and the nozzle connecting nut 37 is threadedly connected to the top connecting thread 19. The nozzle connecting nut 37 is limited by a limiting retaining ring 32, so as to facilitate the fixing of the nozzle connecting nut 37 and the top connecting thread 19, and ensure the installation stability of the water outlet nozzle 31.

[0033] Working principle: water flows from the public water pipe into the extended water inlet head 12, and the water enters the buffer chamber 14 through the water inlet pipe 13, and then enters the guide pipe 16 through the buffer chamber 14, and then enters the water outlet pipe 17 through the guide pipe 16. The water passing through the water outlet pipe 17 passes through the filter 33 to effectively filter impurities in the water to prevent impurities in the water from clogging the water spray pipe 35. The water passes through the booster sleeve 34 to increase the pressure and flow rate of the water itself. The high-pressure and high-speed water passes through the water spray pipe 35 and is sprayed out from the diffuser 36. While ensuring a certain spray distance, the diffuser 36 can expand the area of ​​the sprayed water, thereby ensuring the efficiency of the spray. When the water valve is closed or when the water pressure is insufficient, the anti-overflow diaphragm 27 will move downward under the action of the reset spring 25, so that the anti-overflow diaphragm 27 presses against the guide platform 15, blocking the water from entering the guide pipe 16 through the buffer chamber 14, thereby achieving the anti-overflow effect of the nozzle, thereby achieving top drip prevention.
