Description

A flow-adjustable nozzle

technical field

The utility model relates to an adjustable flow nozzle, which belongs to a water-saving irrigation technology in the agricultural field.

Background technique

Sprinkler irrigation technology is an advanced water-saving irrigation technology, which has the advantages of saving water, labor, land, increasing production and improving crop quality. It has strong adaptability, outstanding economic and social benefits, and has been widely used in many countries and regions. and promotion.

Sprinkler is the key equipment that affects the quality of sprinkler irrigation. Major developed countries in the world have been committed to the improvement and research and development of sprinklers. The development trend is to develop in the direction of multi-function, energy saving, low pressure and adjustable flow.

my country's agricultural production is developing in a precise direction. In addition to the timely water supply of sprinkler irrigation technology, it also requires an appropriate amount of water, which can be quantitatively irrigated according to the irrigation information provided by the monitoring system. The current sprinkler irrigation equipment cannot meet the needs of flow adjustment conveniently and quickly. When adjusting the flow, it is necessary to replace nozzles of different sizes or adjust the pressure to achieve it. Therefore, in combination with the needs of current agricultural production, an adjustable flow nozzle was invented to meet the needs of contemporary agriculture for sprinkler irrigation. requirements.

Utility model content

The utility model provides a flow-adjustable nozzle, which solves the problems that the current sprinkling irrigation equipment cannot conveniently and quickly meet the flow regulation requirements, and needs to replace nozzles of different sizes or adjust the pressure to realize the flow regulation.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

An adjustable flow nozzle, including a shell and a core, the core can be freely screwed out or screwed into the shell, wherein, the area of the water outlet of the core is as the core is screwed out or Screw-in case changes.

Further, a preferred solution of the present utility model: the inside of the shell is hollow, the upper part is a cylindrical water outlet, the lower part is a cone, the core body includes a conical cylinder, and the core body is There are several gaps, and the width of the gaps gradually decreases from the top to the bottom of the conical cylinder. With such a structure of the shell and the core body, the structure is simple and the installation is convenient.

Further, a preferred solution of the present invention: the notch is triangular or trapezoidal. The triangular or trapezoidal structure is adopted. On the one hand, such a notch is easy to process and low in cost. On the other hand, after removing the notch part, the overall core body will not be greatly damaged, and the strength is still very good.

Further, in a preferred solution of the present invention: the lower part of the cone is provided with an internal thread; the outside of the lower part of the core is provided with an external thread matching the internal thread. The structure of internal and external threads is adopted to facilitate the screwing out and screwing in of the core body, and the processing is simple.

Further, a preferred solution of the present utility model: the number of said notches is 6. The number of gaps is limited to 6, which can well adjust the area of the water outlet of the core body and minimize the impact on the strength of the core body.

The beneficial effects of the utility model:

The flow-adjustable nozzle of the utility model has a simple structure and is easy to install. By rotating the shell of the nozzle, the area of the water outlet can be changed quickly and conveniently, and then the flow rate can be changed to achieve flow regulation.

Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1-3, an adjustable flow nozzle includes a shell 2 and a core 6, the core 6 can be freely screwed out or screwed into the shell 2, and the area of the water outlet of the core 6 follows the rotation of the core. Out or screw into the housing 2 changes.

Preferably: the shell 2 is hollow inside, the upper part is a cylindrical water outlet 1, the lower part is a cone 3, the core body includes a conical cylinder 4 and a cylindrical nozzle connector 7, the conical cylinder 4 and The cylindrical nozzle connecting body 7 is an integral structure, and several notches 5 are opened on the conical barrel 4 , and the width of the notches 5 gradually decreases from the top to the bottom of the conical barrel 4 . With such a structure of the shell and the core body, the structure is simple and the installation is convenient.

Preferably: the notch 5 is triangular or trapezoidal. The triangular or trapezoidal structure is adopted. On the one hand, such a notch is easy to process and low in cost. On the other hand, after removing the notch part, the overall core body will not be greatly damaged, and the strength is still very good. The notches 5 in this embodiment are triangular, and the number is 6.

Preferably: the lower part of the cone body 3 is provided with an internal thread 8 ; the outside of the lower part of the conical cylinder 4 is provided with an external thread 9 matching the internal thread 8 . The structure of internal and external threads is adopted to facilitate the screwing out and screwing in of the core body, and the processing is simple.

The utility model using method:

Install the adjustable flow nozzle of the present invention on the nozzle through the nozzle connecting body, the water flow enters from the nozzle, sprays through the core body, puts the shell on the core body, and the inner thread of the shell and the outer thread of the core engage each other to connect the shell and the core Connected into one; rotate the shell, the gap on the core gradually becomes smaller through the compression of the cone, and the area of the water flow through the nozzle also changes accordingly, and finally the water sprayed by the nozzle drives the core to change the size of the outflow area through the rotating shell, reaching The flow rate is adjustable.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.
