Description

Technical Field

[0001] This utility model relates to the field of pressure compensation nozzle technology, and specifically to a pressure compensation nozzle that is easy to install. Background Technology

[0002] Water-saving irrigation, as an important approach in the development of water-saving irrigation in agriculture, is an inevitable trend in the development of resource-saving and environmentally friendly modern agriculture. Micro-sprinklers are a new type of sprinkler irrigation technology that has been widely promoted in recent years. Through a rational design, water from the pump pipeline is evenly dispersed and sprayed out through the unique structure of the micro-sprinkler. The pump pressure drives the rotation of the micro-sprinkler, ultimately achieving a sufficiently large spraying area and realizing the micro-sprinkler effect. This sprinkler irrigation technology directly controls the spraying range and spray volume by adjusting the operating height of the micro-sprinkler, ending the era of water-wasting flood irrigation and demonstrating significant water-saving and yield-promoting effects.

[0003] Because of its simple structure and ease of use, this type of rotary micro-sprinkler is widely used in irrigation operations for lawns, flower beds, vegetable gardens, etc. However, its shortcomings are: the flow rate of existing micro-sprinklers is usually proportional to the pressure. The higher the pressure, the higher the flow rate, which will lead to a situation where the amount of water obtained by the front-end crop is inconsistent with the amount of water and nutrients obtained by the middle and end crops, thus affecting crop yield and quality. Utility Model Content

[0006] Preferably, a threaded pipe is fixedly connected to the bottom of the mounting base.

[0007] Preferably, the adapter is cylindrical, has a cavity inside, the diameter of the adapter is smaller than the diameter of the baffle, and the adapter has a through hole.

[0008] Preferably, the mounting base has a through hole inside, and the through hole of the mounting base communicates with the through hole of the adapter.

[0009] The beneficial effects of this utility model are reflected in the following: This utility model uses a pressure compensation component at the fluid outlet of the nozzle; under water pressure, the pressure compensation component will move along the fluid direction in the cavity, and within a certain pressure difference range, the spraying distance of the fluid will always be guaranteed, thereby ensuring the consistency of water and nutrients obtained by the crop.

[0017] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0019] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific implementation of this utility model will be described in detail below with reference to specific embodiments: such as Figures 1-5 The present invention is achieved through the following technical solution: a pressure compensation nozzle that is easy to install, including a mounting base 6, characterized in that: a sleeve 7 is threadedly connected to the mounting base 6, an adapter 9 is fixedly connected inside the sleeve 7, the adapter 9 is cylindrical, a cavity is opened inside the adapter 9, a through hole is opened in the adapter 9, a pressure compensation component 4 is slidably connected inside the cavity 9 of the adapter 9, a water outlet channel is opened on the pressure compensation component, a baffle 3 is fixedly connected to the top of the pressure compensation component 4, the diameter of the adapter 9 is smaller than the diameter of the baffle 3, an optical axis 8 is connected to the baffle 3, the optical axis 8 is slidably connected inside the limiting part 2, the limiting part 2 is fixedly connected to the mounting arm 1, the mounting arm 1 is fixedly connected to the sleeve 5, a threaded tube 7 is fixedly connected to the bottom of the mounting base 6, a through hole is opened inside the mounting base 6, and the through hole of the mounting base 6 communicates with the through hole of the adapter 9.

[0022] The working principle of this utility model is as follows: During installation, the bottom threaded pipe 7 is tightened for installation. Water flows through the threaded pipe 7 into the mounting base 6 and then through the through hole of the adapter 9 into the cavity of the adapter 9. When the water pressure is high, the water flow lifts the pressure compensation component 4. At this time, the opening between the pressure compensation component 4 and the adapter 9 becomes larger, reducing the water pressure. The optical shaft 8 is slidably connected in the limiting part 2, which can prevent the pressure compensation component 4 from undergoing horizontal displacement. At the same time, the limiting part 2 presses against the baffle 3 to prevent the pressure compensation component 4 from detaching from the adapter 9. When the water pressure is low, the water flow lifts the pressure compensation component 4 to a lower height. At this time, the opening between the pressure compensation component 4 and the adapter 9 becomes smaller, and the water pressure changes dynamically at all times.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
