Description

Technical Field

[0001] This utility model relates to a high-concentration brine pipeline flushing valve used in the production of wet electronic chemicals. Background Technology

[0002] In the production of wet electronic chemicals, high-concentration brine is a key raw material or byproduct, and the smoothness of its delivery pipeline directly affects production efficiency and product quality. However, due to its extremely high solute concentration, high-concentration brine is prone to crystallization and deposition on the inner wall of the pipeline, especially in areas with changes in flow rate, temperature fluctuations, or pipeline turns, which can easily lead to local blockages.

[0003] Existing systems typically have a single flushing port at the end of the pipeline. When a blockage occurs in the middle of the pipeline, the flushing fluid must flow through the entire pipeline to reach the blockage point, resulting in a long flushing path and high fluid resistance. This not only leads to low efficiency but also wastes energy. Furthermore, traditional flushing valves use flanges or threaded connections, requiring multiple sets of bolts for tightening during installation. This process is time-consuming and prone to sealing failure due to misalignment. Leakage is also likely to occur during high-pressure flushing, exacerbating the risk of corrosion to equipment from high-concentration brine. In view of this, this utility model proposes a high-concentration brine pipeline flushing valve for wet electronic chemical production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-concentration brine pipeline flushing valve for wet electronic chemical production, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-concentration brine pipeline flushing valve for wet electronic chemical production is installed on a raw material pipeline. Multiple sets of installation pipes are evenly arranged on the raw material pipeline, and a valve body is installed on each of the multiple sets of installation pipes.

[0007] The valve body is provided with a first connecting pipe, the first connecting pipe is provided with a second connecting pipe, the second connecting pipe is provided with a flushing liquid supply pipe, and the outer wall of the second connecting pipe is provided with a connecting component. The connecting component cooperates with the outer wall of the first connecting pipe to make the first connecting pipe and the second connecting pipe seal together.

[0008] As an improvement to the above technical solution, the outer wall of the second connecting pipe is provided with a connecting annular outer wall, and the flushing liquid supply pipe is fixedly installed on the connecting annular outer wall.

[0009] As an improvement to the above technical solution, the inner wall of the second connecting pipe is provided with an extension pipe, which contacts the inner wall of the first connecting pipe.

[0010] The first connecting pipe and the second connecting pipe are sealed together, so that the extension pipe extends into the inner cavity of the first connecting pipe.

[0011] As an improvement to the above technical solution, a sealing annular groove is provided on the end face of the first connecting pipe;

[0012] The end face of the second connecting pipe is provided with an annular sealing gasket, which is matched with the sealing annular groove. The first connecting pipe and the second connecting pipe are sealed together, so that the annular sealing gasket extends into the sealing annular groove to perform the sealing process.

[0013] As an improvement to the above technical solution, the end face of the first connecting tube is provided with multiple sets of positioning holes, and the multiple sets of positioning holes are arranged in a ring array with the axis of the first connecting tube.

[0014] The end face of the second connecting pipe is provided with multiple sets of positioning rods, and the multiple sets of positioning rods are respectively matched with multiple sets of positioning holes. The first connecting pipe and the second connecting pipe are sealed together, so that the positioning rods extend into the positioning holes.

[0015] As an improvement to the above technical solution, a connecting ring plate is provided on the outer wall of the second connecting pipe, and the diameter of the connecting ring plate matches the diameter of the first connecting pipe;

[0016] The annular sealing gasket and positioning rod are both mounted on the connecting ring plate.

[0017] As an improvement to the above technical solution, the outer wall of the first connecting pipe is provided with a threaded outer wall;

[0018] The connecting assembly includes a connecting sleeve, which rotates to be disposed on a connecting ring plate. The connecting sleeve is threadedly engaged with the outer wall of the threaded part, so that the end faces of the first connecting pipe and the second connecting pipe are connected.

[0019] As an improvement to the above technical solution, the connecting ring plate is provided with a rotating annular groove;

[0020] The inner wall of the connecting sleeve is provided with a connecting ring, and a rotating ring is provided on the connecting ring. The rotating ring is matched in position and size with the rotating annular groove.

[0021] As an improvement to the above technical solution, two sets of positioning bolts are symmetrically arranged on the connecting sleeve, and the positioning bolts are threadedly connected to the connecting sleeve.

[0022] A positioning arc plate is rotatably mounted on the positioning bolt. The positioning arc plate is located in the inner cavity of the connecting sleeve. The positioning arc plate contacts the outer wall of the second connecting pipe, so that the connecting sleeve is locked on the outer wall of the connecting ring plate.

Moreover, after the operation is completed, the flushing supply pipe can be easily disassembled and transferred to other valve bodies, making the operation simple and efficient.

[0026] The flushing operation only requires access to the flushing fluid through the nearest valve body, without disassembling the main body of the raw material pipeline or interrupting the operation of other parts of the system. This non-invasive connection method minimizes the risk of external contamination introduced by disassembly, meets the stringent requirements of ultra-high cleanliness for wet electronic chemical production, and at the same time minimizes production downtime and ensures the continuity of the production process.

[0027] A single flushing supply pipeline can be flexibly connected to any preset valve body position, realizing centralized management and on-demand allocation of flushing resources. This avoids redundant investment in laying fixed flushing supply pipelines at each potential blockage point. Combined with the valve body's rapid opening and closing function, it significantly reduces the complexity and time cost of system maintenance. Attached Figure Description

Detailed Implementation

[0039] 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.

[0040] Example:

[0041] like Figure 1-10 As shown, this embodiment proposes a high-concentration brine pipeline flushing valve for wet electronic chemical production, which is installed on the raw material pipeline 10. Multiple sets of installation pipes 11 are evenly arranged on the raw material pipeline 10, and valve bodies 20 are installed on each of the multiple sets of installation pipes 11.

[0042] The valve body 20 is provided with a first connecting pipe 50, a second connecting pipe 60 is provided on the first connecting pipe 50, a flushing liquid supply pipe 40 is provided on the second connecting pipe 60, and a connecting component 30 is provided on the outer wall of the second connecting pipe 60. The connecting component 30 cooperates with the outer wall of the first connecting pipe 50 so that the first connecting pipe 50 and the second connecting pipe 60 are sealed together.

[0043] In this embodiment, when it is necessary to clean the blockage of the raw material pipeline 10, the blockage is first identified. A portable acoustic sensor can be used to scan along the pipeline by placing it close to the outer wall of the raw material pipeline 10. The blockage can be identified by the abnormal fluid noise attenuation caused by the empty pipe downstream or the high-frequency vibration signal caused by the enhanced turbulence upstream.

[0044] After the judgment is completed, the flushing supply pipe 40 is connected to the valve body 20 closest to the blockage. During the connection process, the second connecting pipe 60 is first aligned with the first connecting pipe 50, and the connecting component 30 is wrapped around the outer wall of the first connecting pipe 50. By the cooperation of the connecting component 30 and the outer wall of the first connecting pipe 50, the first connecting pipe 50 and the second connecting pipe 60 are sealed and connected, and the installation of the flushing supply pipe 40 is completed. Then, the valve body 20 is opened to allow the flushing liquid in the flushing supply pipe 40 to enter the raw material pipe 10, and the flushing process is completed.

[0045] Of course, after the flushing process is completed, the valve body 20 here is closed and the flushing supply pipe 40 is disassembled so that it can be connected to other valve bodies 20 near the blockage area next time.

[0046] By evenly arranging multiple sets of valve bodies 20 with first connecting pipes 50 along the raw material pipeline 10, when the raw material pipeline 10 is blocked, the operator can quickly select and connect the valve body 20 closest to the blockage point, so as to shorten the flushing fluid transmission path, greatly improve flushing efficiency and targeting, and effectively avoid the time and energy consumption problems of traditional systems that need to be flushed remotely from the pipeline endpoint.

[0047] By cooperating with the outer wall of the first connecting pipe 50, the connecting component 30 set on the second connecting pipe 60 can achieve one-step quick alignment and high-sealing docking between the flushing supply pipe 40 and the valve body 20, ensuring the stability of the connection under high-pressure flushing conditions. Moreover, after the operation is completed, the flushing supply pipe 40 can be easily disassembled and transferred to other valve bodies 20, making the operation simple and efficient.

[0048] The rinsing operation only requires access to the rinsing fluid through the nearest valve body 20, without disassembling the main body of the raw material pipeline 10 or interrupting the operation of other parts of the system. This non-invasive connection method minimizes the risk of external contamination introduced by disassembly, meets the stringent requirements of ultra-high cleanliness for wet electronic chemical production, and at the same time minimizes production downtime and ensures the continuity of the production process.

[0049] A single flushing supply pipeline 40 can be flexibly connected to any preset valve body 20 position, realizing centralized management and on-demand allocation of flushing resources. This avoids redundant investment in laying a fixed flushing supply pipeline 40 at each potential blockage point. Combined with the quick opening and closing function of the valve body 20, it significantly reduces the complexity and time cost of system maintenance.

[0050] Specifically, the outer wall of the second connecting pipe 60 is provided with a connecting annular outer wall 61, and the flushing liquid supply pipe 40 is fixedly installed on the connecting annular outer wall 61.

[0051] In this embodiment, by coaxially fixing the flushing supply pipe 40 to the annular connection structure on the outer wall of the second connecting pipe 60, the structural integration of the flushing supply pipe 40 and the connecting component 30 is achieved. This can enhance the radial support strength and bending stiffness of the joint between the second connecting pipe 60 and the flushing supply pipe 40, and effectively avoid the risk of connection deformation or leakage caused by fluid impact under high-pressure flushing conditions.

[0052] Specifically, the inner wall of the second connecting pipe 60 is provided with an extension pipe 62, which is in contact with the inner wall of the first connecting pipe 50;

[0053] The first connecting pipe 50 and the second connecting pipe 60 are sealed together, so that the extension pipe 62 extends into the inner cavity of the first connecting pipe 50.

[0054] In this embodiment, a nested fluid channel is formed by extending the pipe 62 structure. When docking, it is inserted into the inner cavity of the first connecting pipe 50. The tight fit between the outer wall of the extending pipe 62 and the inner wall of the first connecting pipe 50 forms the first radial seal, which effectively prevents high concentration of brine from seeping into the connection interface.

[0055] Of course, the insertion design of the extension pipe 62 can directly introduce the flushing fluid into the central area of ​​the raw material pipe 10, avoiding turbulence or dead zones at the connection port, and significantly improving flushing efficiency and flow field stability.

[0056] Specifically, a sealing annular groove 53 is provided on the end face of the first connecting pipe 50;

[0057] The end face of the second connecting pipe 60 is provided with an annular sealing gasket 63, which is matched with the sealing annular groove 53. The first connecting pipe 50 and the second connecting pipe 60 are sealed together, so that the annular sealing gasket 63 extends into the sealing annular groove 53 to perform the sealing process.

[0058] In this embodiment, through the embedded matching design of the annular sealing gasket 63 and the sealing annular groove 53, the sealing gasket is forced to undergo controllable axial compression and radial deformation during the locking process of the connecting component 30, forming a sealing interface with high elastic recovery force. This can significantly improve the sealing reliability under extreme working conditions (high pressure, temperature fluctuation). At the same time, the sealing annular groove 53 effectively prevents sealing failure caused by assembly misalignment or vibration by positioning the sealing gasket, thus extending the service life of the sealing component.

[0059] Specifically, the end face of the first connecting pipe 50 is provided with a plurality of positioning holes 51, and the plurality of positioning holes 51 are arranged in a ring array with respect to the axis of the first connecting pipe 50.

[0060] The end face of the second connecting pipe 60 is provided with multiple sets of positioning rods 64, and the multiple sets of positioning rods 64 are respectively matched with multiple sets of positioning holes 51. The first connecting pipe 50 and the second connecting pipe 60 are sealed together, so that the positioning rods 64 extend into the positioning holes 51.

[0061] In this embodiment, through the precise insertion and engagement of multiple sets of positioning rods 64 and positioning holes 51, axial alignment and circumferential angular constraint are achieved in the initial stage of docking between the first connecting pipe 50 and the second connecting pipe 60, eliminating the risk of misalignment between the sealing interface, i.e., the annular groove and the sealing gasket.

[0062] Specifically, a connecting ring plate 65 is provided on the outer wall of the second connecting pipe 60, and the diameter of the connecting ring plate 65 matches the diameter of the first connecting pipe 50;

[0063] The annular sealing gasket 63 and the positioning rod 64 are both mounted on the connecting ring plate 65.

[0064] In this embodiment, the outer diameter of the connecting ring plate 65 is consistent with that of the first connecting pipe 50, providing a visual and tactile alignment reference in the initial docking stage, so that the operator can quickly achieve rough positioning of the two pipe axes without additional measuring tools, which can improve assembly efficiency.

[0065] Specifically, the outer wall of the first connecting pipe 50 is provided with a threaded outer wall 52;

[0066] The connecting assembly 30 includes a connecting sleeve 31, which rotates to be disposed on the connecting ring plate 65. The connecting sleeve 31 is threadedly engaged with the threaded outer wall 52, so that the end faces of the first connecting pipe 50 and the second connecting pipe 60 are connected.

[0067] In this embodiment, the rotational torque is converted into a precise axial clamping force by the screwing action of the connecting sleeve 31 and the threaded outer wall 52 of the first connecting tube 50, which drives the connecting ring plate 65 of the second connecting tube 60 to fit tightly with the end face of the first connecting tube 50. This can greatly reduce the complexity of operation and tool dependence, and is especially suitable for the harsh working conditions in the production of wet electronic chemicals that require frequent disassembly and cleaning.

[0068] Specifically, the connecting ring plate 65 has a rotating annular groove 66.

[0069] The inner wall of the connecting sleeve 31 is provided with a connecting ring 33, and a rotating ring 32 is provided on the connecting ring 33. The rotating ring 32 is matched in position and size with the rotating annular groove 66.

[0070] In this embodiment, the combination of the rotating ring 32 and the rotating annular groove 66 facilitates the rotatable connection of the connecting sleeve 31 to the outer wall of the first connecting pipe 50.

[0071] Specifically, two sets of positioning bolts 34 are symmetrically arranged on the connecting sleeve 31, and the positioning bolts 34 are threadedly connected to the connecting sleeve 31.

[0072] A positioning arc plate 35 is rotatably mounted on the positioning bolt 34. The positioning arc plate 35 is located in the inner cavity of the connecting sleeve 31. The positioning arc plate 35 contacts the outer wall of the second connecting pipe 60, so that the connecting sleeve 31 is locked on the outer wall of the connecting ring plate 65.

[0073] In this embodiment, when the connecting sleeve 31 is connected to the outer wall of the first connecting pipe 50, by rotating the positioning bolt 34, the positioning arc plate 35 is displaced toward the outer wall of the second connecting pipe 60 under the threaded engagement of the positioning bolt 34 and the connecting sleeve 31. Since the positioning rod 64 extends into the positioning hole 51, it can prevent rotation between the second connecting pipe 60 and the first connecting pipe 50. After the positioning arc plate 35 contacts the outer wall of the second connecting pipe 60, the connecting sleeve 31 can be prevented from rotating under the action of friction, thereby effectively improving the stability of the connection in the rinsing process.

[0074] Of course, after the positioning arc plate 35 is no longer in contact with the outer wall of the second connecting pipe 60, the connecting sleeve 31 can be rotated by two sets of positioning bolts 34.

[0075] 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.
