Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

As shown in fig. 1 to 6, a fan-shaped spray nozzle with adjustable flow rate comprises a nozzle opening adjusting device and a spray head body 5, wherein an external thread 503 of the spray head body 5 is connected with an internal thread 601 of a pipeline gradual interface 6; the nozzle body 5 is internally provided with a flow guide fan 7, the front end face 701 of the flow guide fan 7 is in contact positioning with the external thread end face 406 of the nozzle inner body 4, and the rear end face 703 of the flow guide fan 7 is in contact positioning with the stepped inner hole end face 602 of the pipeline progressive interface 6. The external thread 405 of the nozzle inner body 4 is screwed into the screw hole 501 of the nozzle body 5.

The nozzle opening adjusting device comprises a nozzle inner body 4, two nozzle outer bodies 3, two bolts 1 and two springs 2, wherein guide blocks 302 of the two nozzle outer bodies 3 are respectively inserted into a slot 401 and a slot 404 on the nozzle inner body 4, the two bolts 1 respectively penetrate through holes 301 of the two nozzle outer bodies 3, penetrate through the springs 2 and are screwed into threaded holes 403 of the nozzle inner body 4, and positioning and jacking of the two nozzle outer bodies are realized. The spring 2 is arranged between the nozzle inner body 4 and the nozzle outer body 3, is sleeved on the bolt 1 and plays a role of jacking. After the installation is finished, the spring 2 has a certain pretightening force to realize the tight jacking of the nozzle outer body 3.

The progressive interface 502 on the spray head body 5 is an air inlet, the progressive interface 603 of the pipeline progressive interface 6 is a liquid inlet, and the progressive interface and the liquid inlet both adopt progressive structures, so that a transfusion pipe and a gas pipe can be easily butted.

The position of the fracture 702 is opposite to the air inlet after the flow guide fan 7 is installed.

The structure of the nozzle inner body 4 is symmetrical about the central line of the inner hole 402, the design can ensure that the structures of the two nozzle outer bodies 3 are completely the same, the additional expenditure for manufacturing the two nozzle outer bodies 3 is saved, the consumption of manpower and material resources when the two structures are required to be processed is reduced, and the processing cost is greatly saved.

When the fog amount is too large, the bolts 1 on the two sides can be rotated rightwards, and the axial feeding of the bolts 1 is realized through the rotating motion of the bolts 1, so that the nozzle outer bodies 3 are driven to slide on the nozzle inner body 4, and the opposite motion of the two nozzle outer bodies 3 is realized. Every rotatory a week of bolt 1 can drive the 3 axial displacement of nozzle outer body helical pitch of a screw thread, through the regulation of angle, and then realize the more meticulous regulation of displacement, can improve the precision of nozzle mouth size adjustment. In the process, the spring 2 always pushes the nozzle outer body 3 tightly and is in a working state. In the process, the nozzle opening is adjusted to be small through the right rotation of the bolt 1, and the mist quantity is adjusted to be small.

When the fog amount is too small, the bolts 1 on both sides can be rotated to the left, when the bolts 1 are rotated to the left, the bolts 1 can be continuously screwed out of the threaded holes 403 on the nozzle inner body 4, and the nozzle outer body 3 can move outwards along with the bolts 1 due to the elastic force of the spring 2. Through the bolt 1 of levogyration both sides, can realize the back-to-back motion of two nozzle outer bodies 3, and then increaseing the nozzle mouth, realized the accent of fog volume greatly.

In the invention, the size of the mist quantity can be changed at any time according to the actual spraying effect, and the progressive interface is convenient for the butt joint of the pipe orifice.

1. the device has simple structure and convenient installation.

2. The novel electric heating furnace is composed of a plurality of parts, only one part can be replaced in later maintenance, cost is saved, and resources are saved.

3. The outer body structures of the two nozzles are completely the same, so that the left and the right are not required to be distinguished, the production process is simplified, and the installation of a user is facilitated.

4. The operation is simple, complex steps are not needed in the operation process, and workers can directly operate the device.

5. The progressive interface makes the docking of the lines easier.

6. The size of the nozzle opening is adjusted with high precision.
