Description

Technical Field

[0001] This utility model relates to the field of vortex nozzle technology, specifically an adjustable square vortex nozzle. Background Technology

[0002] A vortex nozzle is a specially designed nozzle that enhances the spraying effect by generating a rotating airflow. It is widely used in the fields of gas or liquid atomization, dispersion and spray control. The vortex nozzle utilizes the principles of fluid dynamics to generate vortices or eddies within the nozzle, which can achieve a finer and more uniform spraying effect and has higher efficiency. Its main feature is that the ejected fluid has a rotating motion through vortex motion, thereby changing the fluid's spraying characteristics.

[0003] Traditional vortex nozzles spray in a circular shape, which cannot evenly cover the required area in many applications, requiring the installation of multiple nozzles, increasing the cost of water pump production. Furthermore, the flow rate cannot be adjusted during spraying, reducing the applicability of vortex nozzles. Therefore, an adjustable square vortex nozzle is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable square vortex nozzle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable square vortex nozzle, comprising a square vortex nozzle body; a connecting pipe is installed at one end of the square vortex nozzle body, a flow channel is opened inside the connecting pipe, and a flow adjustment mechanism is provided on the side of the connecting pipe;

[0006] Preferably, the flow regulating mechanism includes a fixed sleeve installed on the side of the connecting pipe, a limiting plate installed at one end of the fixed sleeve, a symmetrical through hole at one end of the limiting plate, two guide posts installed inside the fixed sleeve, springs sleeved on the sides of the guide posts, a rotating rod rotatably installed at one end of the fixed sleeve, a rotating block installed at one end of the rotating rod, a flow baffle plate installed on the side of the rotating rod, and a second sealing ring installed at one end of the flow baffle plate.

[0007] Preferably, a connecting groove is provided at one end of the square vortex nozzle body, and a connecting ring is installed at one end of the connecting pipe, wherein the connecting groove and the connecting ring are adapted to each other.

[0008] Preferably, a sealing groove is provided at one end of the square vortex nozzle body, and a first sealing ring is installed at one end of the connecting pipe, wherein the sealing groove is adapted to the first sealing ring.

[0009] Preferably, two butterfly blocks are installed at one end of the rotating block, and a symmetrical auxiliary plate is installed at one end of the limiting plate.

[0010] Preferably, the limiting plate is slidably installed inside the fixed sleeve, and the limiting plate is adapted to the rotating block.

[0011] Preferably, one end of the spring is mounted on the inner wall of the fixed sleeve, and the other end of the spring is mounted on the limiting plate.

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

[0013] (1) By setting a limiting plate and perforations, when it is necessary to adjust the flow rate of the main body of the square vortex nozzle, the limiting plate is pressed and slid at one end of the fixed sleeve, so that the limiting plate is separated from the rotating block, the guide column is compressed, the rotating block is rotated and the rotating rod is rotated, which in turn drives the flow barrier plate in the flow channel to rotate, so that the contact area between the flow barrier plate and the fluid changes, thus completing the flow rate adjustment. After the limiting plate is released, the guide column rebounds and causes the limiting plate to fit against the side of the rotating block, fixing the position of the rotating block, and then fixing the position of the flow barrier plate, so that the flow rate tends to be stable.

[0014] (2) By setting up a butterfly block and an auxiliary plate, when it is necessary to adjust the limiting plate and the rotating block, the rotating block can be rotated by the butterfly block, so that the operator can use force when rotating to adjust the flow plate more quickly. The auxiliary plate can press the limiting plate into the fixed sleeve without having to put the fingers into the fixed sleeve, leaving enough space when rotating the rotating block, making it more convenient for the operator to adjust and improving the applicability of the device.

[0023] 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.

[0024] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: an adjustable square vortex nozzle, comprising a square vortex nozzle body 1; a connecting pipe 3 is installed at one end of the square vortex nozzle body 1, a flow channel 4 is opened inside the connecting pipe 3, and a flow regulating mechanism 2 is provided on the side of the connecting pipe 3; the flow regulating mechanism 2 includes a fixing sleeve 21 installed on the side of the connecting pipe 3, a limiting plate 22 is installed at one end of the fixing sleeve 21, a symmetrical through hole 23 is opened at one end of the limiting plate 22, two guide posts 24 are installed inside the fixing sleeve 21, and springs 25 are sleeved on the side of the guide posts 24. A rotating rod 26 is rotatably mounted on one end of the fixed sleeve 21, a rotating block 27 is mounted on one end of the rotating rod 26, a baffle plate 28 is mounted on the side of the rotating rod 26, a second sealing ring 29 is mounted on one end of the baffle plate 28, two butterfly blocks 9 are mounted on one end of the rotating block 27, symmetrical auxiliary plates 10 are mounted on one end of the limiting plate 22, the limiting plate 22 is slidably mounted inside the fixed sleeve 21, the limiting plate 22 is adapted to the rotating block 27, one end of the spring 25 is mounted on the inner wall of the fixed sleeve 21, and the other end of the spring 25 is mounted on the limiting plate 22. When When the flow rate of the square vortex nozzle body 1 needs to be adjusted, the auxiliary plate 10 is pressed down to drive the limiting plate 22 to slide into the fixed sleeve 21. The limiting plate 22 moves under the limitation of the guide post 24, compressing the spring 25 in the fixed sleeve 21. At the same time, the opening on the limiting plate 22 separates from the rotating block 27, releasing the limitation on the rotating block 27. At this time, the rotating block 27 can be rotated by the butterfly block 9. The rotating block 27 drives the rotating rod 26 to rotate, which in turn drives the flow baffle 28 in the flow channel 4 to rotate. The position of the rotating baffle 28 in the flow channel 4 is adjusted by the rotation of the flow baffle 28. The flow rate is adjusted by adjusting the contact area between the side of the baffle plate 28 and the fluid. After the auxiliary plate 10 is released, the spring 25 returns the limiting plate 22 to its original position and abuts against the side of the rotating block 27, fixing the position of the baffle plate 28 and stabilizing the flow rate. When the baffle plate 28 is in contact with the inner wall of the flow channel 4, the second sealing ring 29 blocks and seals the fluid. The flow rate in the flow channel 4 is controlled by rotating the baffle plate 28, thereby adjusting the outflow at the main body 1 of the square vortex nozzle and uniformly spraying the required area.

[0025] Example 2: As Figure 2 and 3As shown, a connecting groove 5 is provided at one end of the square vortex nozzle body 1, and a connecting ring 7 is installed at one end of the connecting pipe 3. The connecting groove 5 and the connecting ring 7 are adapted to each other. A sealing groove 6 is provided at one end of the square vortex nozzle body 1, and a first sealing ring 8 is installed at one end of the connecting pipe 3. The sealing groove 6 and the first sealing ring 8 are adapted to each other. When not in use, the connecting pipe 3 can be removed, and the connecting ring 7 can be separated from the thread in the connecting groove 5 by rotating the connecting pipe 3, thus canceling the connection between the square vortex nozzle body 1 and the connecting pipe 3. When in use, the first sealing ring 8 in the sealing groove 6 can ensure the tightness of the connection between the square vortex nozzle body 1 and the connecting pipe 3, improving the applicability of the device. The remaining features are the same as in Embodiment 1.

[0026] The working principle is as follows: When it is necessary to adjust the flow rate of the square vortex nozzle body 1, the auxiliary plate 10 is pressed down to drive the limiting plate 22 to slide into the fixed sleeve 21. The limiting plate 22 moves under the limit of the guide post 24, compressing the spring 25 in the fixed sleeve 21. At the same time, the opening on the limiting plate 22 separates from the rotating block 27, releasing the limitation on the rotating block 27. At this time, the rotating block 27 can be rotated by the butterfly block 9. The rotating block 27 drives the rotating rod 26 to rotate, which in turn drives the flow baffle 28 in the flow channel 4 to rotate. By rotating the position of the flow baffle 28 in the flow channel 4, the contact area between the side of the flow baffle 28 and the fluid is adjusted, thereby adjusting the flow rate. After the auxiliary plate 10 is released, the spring 25 rebounds and drives the limiting plate 25 to rotate. Position plate 22 returns to its original position and abuts against the side of rotating block 27, fixing the position of flow baffle 28 and stabilizing the flow rate of the fluid. When flow baffle 28 is in contact with the inner wall of flow channel 4, second sealing ring 29 blocks and seals the fluid. By rotating flow baffle 28, the flow rate in flow channel 4 is controlled, thereby adjusting the outflow at the main body 1 of square vortex nozzle. When not in use, connecting pipe 3 can be removed. By rotating connecting pipe 3, connecting ring 7 is separated from the thread in connecting groove 5, thus canceling the connection between the main body 1 of square vortex nozzle and connecting pipe 3. In use, first sealing ring 8 in sealing groove 6 can ensure the tightness of the connection between main body 1 of square vortex nozzle and connecting pipe 3, improving the applicability of the device.

[0027] 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.
