Description

Technical Field

[0001] This utility model relates to the field of nozzles, specifically to an industrial nozzle with adjustable flow rate. Background Technology

[0002] In the industrial sector, nozzles, as key fluid control components, are widely used in various processes such as spraying, cooling, cleaning, and humidification. However, traditional industrial nozzles have some inherent design flaws that limit their performance and applicability.

[0003] The nozzle is equipped with an external adjusting rotating component for regulating the nozzle flow rate. However, during use, the adjusting rotating component is easily affected by the environment and may rotate, which will eventually change the nozzle flow rate and reduce the overall performance of the nozzle. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned defects and provide an industrial nozzle with adjustable flow rate. This invention solves the technical problem that the existing adjustable rotating parts are easily affected by environmental factors during use, which can cause the nozzle flow rate to change and thus reduce the overall performance of the nozzle.

[0005] The purpose of this utility model is achieved through the following means: an adjustable flow industrial nozzle, comprising a tube body, a nozzle, a fixed perforation plate and a rotatable perforation plate, wherein the nozzle is connected to the upper end face of the tube body, the fixed perforation plate is fixedly assembled in the inner cavity of the tube body, the rotatable perforation plate is rotatably assembled in the inner cavity of the tube body, and locking mechanisms are connected to both sides of the rotatable perforation plate, and a limit plate is sleeved on the outside of the tube body.

[0006] The locking mechanism includes two sets of hollow arms. The hollow arms are connected to a rotatable perforated plate. A sliding arm is slidably connected to the inner cavity of the hollow arm, and a pressure plate is connected to the outside of the sliding arm. A first spring is connected between the sliding arm and the hollow arm. A connecting rod is hinged to the bottom of the sliding arm. A locking arm is hinged to the other end of the connecting rod. A slotted annular block is slidably connected to the outside of the locking arm, and the slotted annular block is connected to the hollow arm.

[0007] Furthermore, both the rotatable perforated plate and the fixed perforated plate have holes at their opposite ends, and the two sets of holes are staggered. The flow rate of the pipe is changed by the staggering of the holes in the rotatable perforated plate and the fixed perforated plate.

[0008] Furthermore, transverse grooves are provided on both outer sides of the tube body. These transverse grooves are slidably connected to the hollow arm, facilitating the transmission of the hollow arm and thereby improving the smoothness of the transmission of the hollow arm.

[0009] Furthermore, a flange is connected to the bottom of the pipe body, and a limit hole is opened on the outside of the flange, which facilitates the connection of the pipe body to an external device.

[0010] Furthermore, the top of the limiting plate is evenly provided with slots, which are slidably connected to the locking arm. The slots facilitate the insertion of the locking arm, thereby locking the position of the rotatable perforated plate.

[0011] Furthermore, a sliding groove is provided at the bottom of the hollow arm, and the sliding groove is slidably connected to the connecting rod. Sliding grooves are provided on both sides of the outer side of the slotted annular block, and the sliding grooves are slidably connected to the locking arm. A second spring is connected between the locking arm and the sliding groove. The sliding groove facilitates the transmission of the connecting rod, guides the locking arm to make it move in a straight line, and the second spring facilitates the locking arm to return to its original position after the movement is completed.

[0012] The beneficial effects of this utility model are as follows: By adding a hollow arm, a rotatable perforated plate, and a fixed perforated plate, the flow rate of the pipe can be adjusted quickly by rotating the rotatable perforated plate and changing the position of the holes in the rotatable and fixed perforated plates during pipe operation, thereby improving the overall practicality of the device. At the same time, by adding a sliding arm, pressure plate, connecting rod, locking arm, and limiting plate, the position of the rotatable perforated plate is automatically locked when the positions of the rotatable and fixed perforated plates change, preventing the rotatable perforated plate from rotating due to external environmental forces, which would cause changes in the flow rate of the pipe.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] In this embodiment, refer to Figure 1and Figure 2 The industrial nozzle with adjustable flow rate specifically implemented includes a tube body 1, a nozzle 2, a fixed orifice plate 3 and a rotatable orifice plate 4. The nozzle 2 is connected to the upper end face of the tube body 1. The fixed orifice plate 3 is fixedly installed in the inner cavity of the tube body 1. The rotatable orifice plate 4 is rotatably installed in the inner cavity of the tube body 1. Locking mechanisms 5 are connected to both sides of the rotatable orifice plate 4. A limit plate 6 is sleeved on the outside of the tube body 1.

[0020] The combination of pipe body 1, nozzle 2, fixed orifice plate 3 and rotatable orifice plate 4 is a common nozzle device in the prior art. The fixed orifice plate 3 is fixed in the inner cavity of pipe body 1 and cannot rotate. The rotatable orifice plate 4 can rotate and cooperate with the fixed orifice plate 3 to change the flow rate of pipe body 1. The nozzle 2 can discharge water from the outlet. The locking mechanism 5 can control the rotation of rotatable orifice plate 4. The limit plate 6 can cooperate with the locking mechanism 5 to lock the position of rotatable orifice plate 4.

[0021] Please see Figure 3 and Figure 4 The locking mechanism 5 includes two sets of hollow arms 51. The hollow arms 51 are connected to the rotatable perforated plate 4. The inner cavity of the hollow arm 51 is slidably connected to the sliding arm 52, and the outer side of the sliding arm 52 is connected to the pressure plate 53. A first spring 56 is connected between the sliding arm 52 and the hollow arm 51. The bottom of the sliding arm 52 is connected to the connecting rod 54 by a hinge. The other end of the connecting rod 54 is connected to the locking arm 55 by a hinge. The outer side of the locking arm 55 is slidably connected to the slotted annular block 58, and the slotted annular block 58 is connected to the hollow arm 51.

[0022] The hollow arm 51 can drive the rotatable perforated plate 4 to move. The sliding arm 52 can slide in the inner cavity of the hollow arm 51. The pressure plate 53 makes it convenient for the operator to drive the sliding arm 52 to move. The connecting rod 54 can drive the locking arm 55 to move. The locking arm 55 can be inserted into the inner cavity of the limiting plate 6 to lock the position of the rotatable perforated plate 4.

[0023] The rotatable perforated plate 4 and the fixed perforated plate 3 each have holes at their opposite ends, and the two sets of holes are staggered. The flow rate of the pipe body 1 is changed by the staggered holes of the rotatable perforated plate 4 and the fixed perforated plate 3. The outer sides of the pipe body 1 are provided with transverse grooves 12, which are slidably connected to the hollow arm 51. The transverse grooves 12 facilitate the transmission of the hollow arm 51, thereby improving the transmission smoothness of the hollow arm 51.

[0024] The bottom of the pipe body 1 is connected to a flange 11. A limiting hole is opened on the outside of the flange 11. The flange 11 facilitates the connection of the pipe body 1 to an external device. The top of the limiting plate 6 is evenly provided with slots. The slots are slidably connected to the locking arm 55. The slots facilitate the insertion of the locking arm 55, thereby locking the position of the rotatable opening plate 4.

[0025] The bottom of the hollow arm 51 is provided with a sliding groove 57, which is slidably connected to the connecting rod 54. The outer sides of the slotted annular block 58 are provided with sliding grooves, which are slidably connected to the locking arm 55. A second spring 59 is connected between the locking arm 55 and the sliding groove. The sliding groove 57 facilitates the transmission of the connecting rod 54, and the sliding groove can guide the locking arm 55 to make it move in a straight line. The second spring 59 facilitates the locking arm 55 to return to its original position after the movement is completed.

[0026] First, the pipe body 1 is connected to the external pipeline through the flange 11. The water source inside the pipeline is sprayed out through the nozzle 2. The rotatable orifice plate 4 is driven to rotate through the hollow arm 51, so that the rotatable orifice plate 4 and the holes on the outside of the fixed orifice plate 3 are intersected, changing the position of the holes, thereby adjusting the flow rate of the pipe body 1.

[0027] After adjustment, release the pressure on the pressure plate 53. At this time, the pressure plate 53 returns to its original position through the first spring 56, and then pushes the locking arm 55 to move through the connecting rod 54, inserting into the inner cavity of the limiting plate 6 to lock the position of the rotatable perforated plate 4.

[0028] By adding a hollow arm 51, a rotatable perforated plate 4, and a fixed perforated plate 3, the flow rate of the pipe body 1 can be quickly adjusted by rotating the rotatable perforated plate 4 and changing the position of the holes in the fixed perforated plate 3 during the operation of the pipe body 1, thereby improving the overall practicality of the device. At the same time, by adding a sliding arm 52, a pressure plate 53, a connecting rod 54, a locking arm 55, and a limiting plate 6, the position of the rotatable perforated plate 4 is automatically locked when the positions of the rotatable perforated plate 4 and the fixed perforated plate 3 change, preventing the rotatable perforated plate 4 from being driven by the external environment to rotate and thus changing the flow rate of the pipe body 1.

[0029] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
