Description

Technical Field

[0001] This utility model relates to the field of vortex nozzle technology, specifically a serrated vortex nozzle with uniform coverage. Background Technology

[0002] Vortex nozzles are industrial equipment widely used in chemical, petroleum, chemical fiber, electronics, and light industries, especially in applications such as gas cooling, gas purification, washing, deoxygenation, desorption, and flue gas dust removal. The technology behind this nozzle was developed to overcome the shortcomings of traditional nozzle materials such as polypropylene (PP), polytetrafluoroethylene (PTFE), brass, and stainless steel, which are characterized by high cost, susceptibility to clogging, and poor wear resistance. Vortex nozzles typically consist of a silicon carbide or stainless steel cast nozzle, a circular inlet pipe connector, and an internally threaded flange. The circular inlet pipe connector is connected to one side of the nozzle, and a circular vortex flow chamber is located in the center, perpendicular to the circular inlet pipe, connecting to a flared nozzle. This design helps to create a vortex flow, improves spray performance, and ensures a smooth, unclogging flow path. The working principle of a vortex nozzle is that the liquid enters the vortex chamber of the nozzle tangentially, and then is ejected from the nozzle orifice at a right angle to the inlet direction, forming a hollow cone-shaped spray pattern. The spray area is annular. This design makes the spray particle size small and uniform, and the vortex channel is large, reducing the possibility of nozzle clogging.

[0003] Common vortex nozzles have a circular nozzle shape with rounded edges. After the liquid is sprayed out, it forms a hollow cone-shaped spray. The water mist particles are relatively coarse and do not achieve the ideal atomization and neutralization effect. In addition, existing nozzles are usually connected by threads. However, when the nozzle is tightened, the nozzle nozzle area is not directly aligned with the spray area. If the nozzle position is adjusted by turning the thread, the thread may not be tightened, making the nozzle easy to loosen. Therefore, a serrated vortex nozzle with uniform coverage is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a serrated vortex nozzle with uniform coverage to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniformly covering serrated vortex nozzle, comprising a vortex nozzle body; a serrated nozzle is fixedly mounted on the vortex nozzle body, the edge of the serrated nozzle being circumferentially distributed serrations; an extension tube is fixedly mounted on one side of the vortex nozzle body, both the serrated nozzle and the extension tube communicating with the interior of the vortex nozzle body; a spray pipe is mounted on one side of the vortex nozzle body, both the extension tube and the spray pipe are provided with connecting devices, and a valve switch device is provided inside the spray pipe;

[0006] Preferably, the connecting device includes a connector, which is fixedly installed on one side of the extension pipe. A first fixing plate is fixedly installed on the connector, and a second fixing plate is fixedly installed on the spray pipe. The first fixing plate and the second fixing plate are equipped with the same fixing bolt and fixing nut.

[0007] Preferably, both the first and second fixing plates have fixing holes, the fixing bolts are installed in the fixing holes, and the fixing nuts are threaded onto the fixing bolts.

[0008] Preferably, the connector has an external thread, the spray pipe has an internal thread, and the connector and the spray pipe are threadedly connected.

[0009] Preferably, the valve switching device includes a switching valve core, which is movably installed inside the spray pipe. A connecting rod is fixedly installed on the switching valve core, and a turntable is fixedly installed on the connecting rod.

[0010] Preferably, the spray pipe has a rotating hole, and the connecting rod is rotatably installed in the rotating hole.

[0011] Preferably, the switch valve core has a flow groove, and the spray pipe communicates with the interior of the vortex nozzle body through the flow groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) In this utility model, the sawtooth nozzle on the vortex nozzle body enables high-speed and high-pressure water flow to impact the sawtooth, thereby causing the water flow to atomize and achieve the effect of fine spraying, so that the sprayed water mist is more uniform in the outer and central areas.

[0014] (2) In this utility model, the thread on the connector head is initially connected to the thread inside the spray pipe. During installation, the connector head is rotated until it is completely screwed into the spray pipe. If the serrated nozzle on the vortex nozzle body is not aligned with the spraying area directly below, the thread is reversed so that the serrated nozzle is aligned with the spraying area. Then, the first and second fixing plates are fixed with fixing bolts and fixing nuts. At this time, the connector head is fixed on the spray pipe.

[0015] (3) In this utility model, by rotating the turntable, the turntable drives the switch valve core to rotate through the connecting rod. After the flow channel is rotated to be perpendicular to the axis of the spray pipe, the switch valve core will block the spray pipe, thereby closing a single spray head. This facilitates the maintenance of a single spray head without affecting the water supply of other spray heads. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a uniformly covering serrated vortex nozzle, including a vortex nozzle body 1; in order to achieve uniform spraying and facilitate connection, a serrated nozzle 6 is fixedly installed on the vortex nozzle body 1. The edge of the serrated nozzle 6 is circumferentially distributed serrations. An extension pipe 4 is fixedly installed on one side of the vortex nozzle body 1. Both the connecting device 3 and the extension pipe 4 are connected to the interior of the vortex nozzle body 1. A spray pipe 5 is installed on one side of the vortex nozzle body 1. Both the extension pipe 4 and the spray pipe 5 are equipped with connecting devices 3. A valve switch device 2 is installed inside the spray pipe 5. The serrated nozzle 6 achieves the function of uniform atomization spraying. The vortex nozzle body 1 and the spray pipe 5 are connected by the connecting device 3. The valve switch device 2 controls the on / off of the water flow in the spray pipe 5.

[0023] To ensure the nozzles can effectively spray the designated area during installation, the connecting device 3 includes a connector 30, which is fixedly mounted on one side of the extension pipe 4. A first fixing plate 31 is fixedly mounted on the connector 30, and a second fixing plate 33 is fixedly mounted on the spray pipe 5. Both the first and second fixing plates 31 and 33 are fitted with the same fixing bolt 35 and fixing nut 32. Both the first and second fixing plates 31 and 33 have fixing holes 34, in which the fixing bolt 35 is installed. The fixing nut 32 is threaded onto the fixing bolt 35. The connector 30 has external threads, and the spray pipe 5 has internal threads. The connector 30 and the spray pipe 5 are threaded together. During installation, a preliminary connection is made between the threads on the connector 30 and the threads inside the spray pipe 5, followed by a rotational connection. The connector 30 is screwed into the spray pipe 5 until it is fully inserted. If the serrated nozzle 6 on the vortex nozzle body 1 is not aligned with the spray area directly below, reverse the thread to align the serrated nozzle 6 with the spray area. Then, use the fixing bolt 35 and fixing nut 32 to fix the first fixing plate 31 and the second fixing plate 33. At this time, the connector 30 is fixed on the spray pipe 5. During operation, multiple vortex nozzle bodies 1 are installed on the spray pipe 5. The spray pipe 5 is usually a multi-port pipe. Water flows into the vortex nozzle body 1 through the spray pipe 5. The serrated nozzle 6 on the vortex nozzle body 1 allows the high-speed and high-pressure water flow to impact the serrations, thereby causing the water flow to atomize and achieve the effect of fine spraying. This makes the sprayed water mist more uniform in both the outer and central areas.

[0024] Example 2: Figure 4 To achieve the function of controlling the water flow switch of a single channel, the valve switch device 2 includes a switch valve core 20, which is movably installed inside the spray pipe 5. A connecting rod 22 is fixedly installed on the switch valve core 20, and a turntable 23 is fixedly installed on the connecting rod 22. A rotating hole 24 is opened on the spray pipe 5, and the connecting rod 22 is rotatably installed in the rotating hole 24. A flow groove 21 is opened on the switch valve core 20, and the spray pipe 5 is connected to the inside of the vortex nozzle body 1 through the flow groove 21. When the nozzle of one channel fails, it is only necessary to rotate the turntable 23 on the corresponding multi-way pipe of the spray pipe 5. The turntable 23 drives the switch valve core 20 to rotate through the connecting rod 22, and rotates the flow groove 21 to be perpendicular to the axis of the spray pipe 5. At this time, the switch valve core 20 will block the spray pipe 5, thereby closing the single nozzle. This facilitates the maintenance of the single nozzle without affecting the water supply of other nozzles. The other features are the same as in embodiment 1.

[0025] The working principle is as follows: During installation, a preliminary connection is made between the thread on the connector 30 and the thread inside the spray pipe 5. The connector 30 is rotated until it is fully screwed into the spray pipe 5. If the serrated nozzle 6 on the vortex nozzle body 1 is not aligned with the spray area directly below, the thread is reversed to align the serrated nozzle 6 with the spray area. Then, the first fixing plate 31 and the second fixing plate 33 are fixed using the fixing bolt 35 and the fixing nut 32. At this point, the connector 30 is fixed to the spray pipe 5. During operation, multiple vortex nozzle bodies 1 are installed on the spray pipe 5. The spray pipe 5 is typically a multi-port pipe, and water flows through the spray pipe 5 into the vortex nozzle body 1. The serrated nozzles 6 on the vortex nozzle body 1 allow high-speed, high-pressure water to impact the serrations, resulting in atomization and a finer spray effect. This makes the sprayed water mist more uniform in both the outer and central areas. When one of the nozzles malfunctions, simply rotate the turntable 23 on the corresponding multi-port pipe of the spray pipe 5. The turntable 23, through the connecting rod 22, drives the switch valve core 20 to rotate, turning the flow channel 21 perpendicular to the axis of the spray pipe 5. At this point, the switch valve core 20 will block the spray pipe 5, thus shutting off a single nozzle. This allows for easy maintenance of a single nozzle without affecting the water supply to other nozzles.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
