Embodiment Construction

[0022] The present invention will now be further described with reference to the drawings and specific embodiments.

[0023] Such as Figure 1-5 As shown, a structure that can adjust the nozzle outlet area includes a top cover 7, a chassis 1, a turntable 2, a connecting rod 3, and a shutter 4. The top cover 7 is a cylindrical structure with front and rear openings. The rear end of the cover 7 is used to be fixed on the outlet end of the nozzle. In this specific implementation, the top cover 7 is preferably a cylindrical structure with a front and rear opening. The rear end of the top cover 7 is provided with an internal thread 6 for communication with The external thread of the nozzle outlet end is screwed and fixed. With this threaded connection structure, there is no need to make too many changes to the nozzle. It is only necessary to machine the outer wall of the nozzle outlet end with external threads, and it is easy to install and disassemble. Of course, in other embodiments...

Abstract

The invention relates to the technical field of injectors, in particular to a structure capable of adjusting the area of an outlet of a spraying nozzle. The structure capable of adjusting the area ofthe outlet of the spraying nozzle comprises a top cover, a chassis, a rotating disc, a connecting rod and shielding plates. The top cover is of a cylindrical structure with openings formed in the front end and the rear end. The rear end of the top cover is used for being fixed to the outlet end of the spraying nozzle. The chassis is of a ring-shaped structure. The chassis is fixedly arranged on the front end face of the top cover. The rotating disc is of a ring-shaped structure and arranged on the chassis in a rotating manner. The shielding plates are connected with the chassis and the connecting rod in a rotating manner correspondingly. The connecting rod is connected with the rotating disc in a rotating manner. The number of the shielding plates is multiple. The multiple shielding platesenclose a round hole of the chassis to form a spraying outlet. The axis of the spraying outlet coincides with the axis of a runner in the spraying nozzle, and when the rotating disc rotates, the connecting rod drives the shielding plates to rotate to change the size of the spraying outlet. The structure is simple, the area of the outlet of the spraying nozzle can be regulated and controlled exquisitely, and automatic adjustment can be achieved.

Description

Technical field [0001] The invention belongs to the technical field of ejectors, and specifically relates to a structure capable of adjusting the nozzle outlet area. Background technique [0002] Nozzles are widely used in today's industrial systems, from aerospace to agricultural irrigation, from air conditioning to fuel atomization, and nozzles are used in all walks of life. In many cases, it is necessary to adjust the spray area and shape of the nozzle outlet. For example, in the field of agricultural irrigation, the area and shape of the irrigation can be changed by adjusting the size of the nozzle outlet area. The flame gun used in the military and industrial fields can control the flame temperature and range by changing the nozzle outlet area. In the field of fire protection, ship fire is recognized as one of the most difficult fires in the world to extinguish. It is a relatively common and extremely dangerous accident. As an indispensable part of the ship's fire fightin...
