Description

Technical Field

[0001] This invention relates to the field of mechanical assembly technology, and more particularly to an easily assembled and disassembled solenoid valve. Background Technology

[0002] The installation structure of a solenoid valve needs to prevent radial or axial displacement of the solenoid components after installation, which could affect the normal operating performance of the solenoid valve, such as sealing and response speed, and may even lead to valve failure. To achieve this, the installation structure needs to be stable to prevent the solenoid components from loosening due to vibration, pressure changes, or other factors during the operation of the solenoid valve.

[0003] Existing solenoid valves are mostly fixed by bolts and welding during installation, which makes disassembly and maintenance very troublesome, increases the workload of personnel, and has low assembly and disassembly efficiency. For example, a Chinese patent with publication number CN217603464U discloses a solenoid valve that is easy to disassemble and assemble. It uses a base mechanism, support mechanism, plug-in mechanism, positioning mechanism, solenoid valve mechanism, connecting pipe, control mechanism, base plate, rubber shock-absorbing pad, support plate, plug-in shell, shell, movable plate, pull rod, positioning spring, positioning pin, positioning groove, positioning cover and plug-in plate to facilitate disassembly, prevent internal parts from loosening, and reduce failure rate. However, this technical solution involves multiple complex connection steps, such as bolt tightening, welding, and gluing, which makes the assembly process cumbersome, time-consuming and labor-intensive, and not conducive to the replacement of parts in subsequent maintenance, and has certain defects in use. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an electromagnetic valve with an assembly structure that is easy to install and disassemble and has high stability.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An easily assembled and disassembled solenoid valve includes a valve seat, a solenoid assembly, and a mounting module. The valve seat is disposed below the solenoid assembly, which controls the opening and closing of the valve seat. The mounting module includes a mounting base, a radial limiting assembly, and an axial limiting assembly. The mounting base connects the valve seat and the solenoid assembly. The radial limiting assembly includes a mounting frame and a guide sleeve. The mounting frame is disposed above the mounting base, and the guide sleeve is disposed within the mounting frame. The solenoid assembly is disposed on the mounting frame and the guide sleeve. The axial limiting assembly includes a first limiting member and a second limiting member. The first limiting member and the second limiting member are disposed on opposite axial sides of the mounting frame. One end of the first limiting member is pressed against the top of the mounting frame, and the other end of the first limiting member is engaged with the bottom of the mounting frame. One end of the second limiting member is engaged with the mounting base, and the other end of the second limiting member is pressed against the top of the mounting frame.

[0007] Furthermore, the electromagnetic component includes an electromagnetic coil and a valve core. The electromagnetic coil is wound around the outside of the mounting frame, and the valve core is sleeved inside the mounting frame. The valve core passes through the mounting seat, and the mounting seat is provided with a limiting step that cooperates with the bottom of the valve core.

[0008] Furthermore, the mounting frame includes a winding post, an upper support plate, and a lower support plate. The winding post connects the upper support plate and the lower support plate. The winding post is a hollow cylinder. The electromagnetic coil is wound around the outside of the winding post, and the guide sleeve is disposed inside the winding post.

[0009] Furthermore, the guide sleeve includes an upper guide sleeve and a lower guide sleeve. The upper guide sleeve is disposed in the upper part of the winding post, and the lower guide sleeve is disposed in the lower part of the winding post. The inner radial sides of the upper guide sleeve and the lower guide sleeve are radially engaged with the outer side of the valve core.

[0010] Furthermore, the first limiting member includes an upper pressing plate, a lower locking plate, and a connecting plate. The connecting plate connects the upper pressing plate and the lower locking plate. The upper pressing plate and the lower locking plate have circular through holes coaxial with the winding post. The portion of the valve core extending out of the guide sleeve is fitted into the circular through hole. The upper pressing plate abuts against the upper support plate. The lower locking plate has a first locking notch. The bottom surface of the lower support plate has a locking protrusion. The first locking notch engages with the locking protrusion.

[0011] Furthermore, a terminal fixing seat is provided on the connecting plate, and a wiring terminal is connected to the terminal fixing seat. The wiring terminal is snapped into the upper support plate and connected to the electromagnetic coil.

[0012] Furthermore, the second limiting member includes an upper pressing arm, a lower locking arm, and a connecting arm. The connecting arm connects the upper pressing arm and the lower locking arm. The upper pressing arm is pressed against the top of the mounting frame. The lower locking arm has a second locking notch, which radially engages with the mounting base.

[0013] Furthermore, the mounting module also includes a protective housing, which houses the electromagnetic component, the radial limiting component, and the first limiting member. The inner top side of the protective housing abuts against the upper pressing plate, and the outer top side of the protective housing is provided with a pressing groove. The upper pressing arm is provided with a pressing arc plate, which presses against the pressing groove. The bottom of the protective housing is located between the snap-fit ​​plate and the mounting base.

[0014] Furthermore, the mounting base includes a flange portion and a threaded portion connected to the flange portion. The end face of the flange portion facing away from the threaded portion is attached to the bottom of the protective housing. The lower snap-fit ​​arm is snapped onto the lower part of the flange portion. The threaded portion is threadedly connected to the valve seat.

[0015] Furthermore, a sealing ring is provided between the bottom radial side of the valve core and the inner side of the mounting base.

[0016] The beneficial effects of this utility model are:

[0017] 1. The easily assembled and disassembled solenoid valve of this utility model adopts crimping, snap-fit ​​and other connection methods between the installation module, solenoid component and valve seat. When assembling the solenoid component, there is no need to use complicated tools or perform tedious bolt tightening, welding and other operations. When disassembling and replacing the solenoid component, there is no need to perform multi-spiral disassembly. Just release the snap-fit ​​relationship through the first limit member and the second limit member to quickly complete the disassembly and installation of the solenoid component. It greatly shortens the maintenance time, improves work efficiency, reduces manpower input and operation difficulty. At the same time, due to the simple installation and disassembly process, the risk of component damage caused by improper operation is reduced.

[0018] 2. The easily assembled and disassembled solenoid valve of this utility model features a radial limiting assembly composed of a mounting frame and a guide sleeve. This assembly provides precise radial positioning for the solenoid component, and the guide sleeve guides the solenoid component into accurate position, preventing radial offset and thus avoiding media leakage caused by radial offset of the solenoid component. This improves the operational reliability of the solenoid valve. The first and second limiting components limit the mounting frame from opposite axial sides, ensuring that the solenoid component remains fixed in the axial direction. This effectively prevents axial movement of the solenoid component due to vibration, pressure changes, or other factors during operation, ensuring the stability of the internal structure of the solenoid valve and improving its response speed and operational accuracy.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "upper," "lower," "inner," "outer," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0028] See Figure 1 , Figure 4An easily detachable solenoid valve includes a valve seat 100, a solenoid assembly 200, and a mounting module 300. The valve seat 100 is disposed below the solenoid assembly 200, which controls the opening and closing of the valve seat 100. The mounting module 300 includes a mounting base 310, a radial limiting assembly 320, and an axial limiting assembly 330. The mounting base 310 is connected between the valve seat 100 and the solenoid assembly 200. The radial limiting assembly 320 includes a mounting frame 321 and a guide sleeve 322. The mounting frame 321 is disposed above the mounting base 310, and the guide sleeve 322 is disposed below the mounting base 310. Inside the mounting frame 310, the electromagnetic component 200 is disposed on the mounting frame 321 and the guide sleeve 322. The axial limiting component 330 includes a first limiting member 331 and a second limiting member 332. The first limiting member 331 and the second limiting member 332 are disposed on opposite axial sides of the mounting frame 321. One end of the first limiting member 331 is pressed against the top of the mounting frame 321, and the other end of the first limiting member 331 is snapped against the bottom of the mounting frame 321. One end of the second limiting member 332 is snapped against the mounting base 321, and the other end of the second limiting member 332 is pressed against the top of the mounting frame 321.

[0029] It should be noted that the mounting module 300 consists of a mounting base 310, a radial limiting component 320, and an axial limiting component 330. The mounting base 321 serves as a bridge connecting the valve seat 100 and the electromagnetic component 200, integrating the various components together to form a stable mounting assembly.

[0030] The radial limiting assembly 320 includes a mounting frame 321 and a guide sleeve 322. The mounting frame 321 is positioned above the mounting base 310, providing a mounting platform for the solenoid assembly 200. The guide sleeve 322 is located inside the mounting frame 321. When the solenoid assembly 200 is installed into the mounting frame 321, the guide sleeve 322 can guide the solenoid assembly 200 to be accurately positioned and radially limit the solenoid assembly 200, preventing the solenoid assembly 200 from shifting in the radial direction. This ensures the accurate relative position between the solenoid assembly 200 and the valve seat 100, guaranteeing the sealing performance and working performance of the solenoid valve.

[0031] The first limiting member 331 and the second limiting member 332 of the axial limiting assembly 330 are disposed on opposite axial sides of the mounting frame 321. The first limiting member 331 is engaged with the mounting frame 321, thereby axially limiting the mounting frame 321 from one side and preventing it from moving to that side. The second limiting member 332 is engaged with the mounting base 310 and pressed against the top of the mounting frame 321. It can be understood that it can be pressed against the mounting frame 321 or other components above the mounting frame 321. In this way, the second limiting member 332 is not only firmly connected to the mounting base 310, but also applies downward pressure to the mounting frame 321, axially limiting the mounting frame 321 from the other side and ensuring that the mounting frame remains stable in the axial direction.

[0032] In other words, the two limiting components work together to ensure the axial position of the electromagnetic assembly is fixed, preventing axial movement during operation and improving the stability and reliability of the electromagnetic valve. Due to the use of snap-fit ​​connections, when it is necessary to disassemble or reassemble the electromagnetic assembly, it is only necessary to release the snap-fit ​​relationship between the first limiting component 331 and the mounting frame 321, and the second limiting component 332 and the mounting base 310, so that the electromagnetic assembly can be easily removed from the mounting module or reinstalled, which greatly simplifies the disassembly and assembly process and improves maintenance and repair efficiency.

[0033] This solenoid valve uses crimping and snap-fit ​​connection methods. When assembling the solenoid components, there is no need to use complicated tools or perform tedious bolt tightening and welding operations. When disassembling and replacing the solenoid components, there is no need to perform multi-spiral disassembly. Simply release the snap-fit ​​relationship between the first limiting member 331 and the second limiting member 332 to quickly complete the disassembly and installation of the solenoid components. This greatly shortens maintenance time, improves work efficiency, reduces manpower input and operation difficulty, and reduces the risk of component damage due to improper operation due to the simple installation and disassembly process. Meanwhile, the radial limiting assembly consisting of the mounting frame 321 and the guide sleeve 322 provides precise radial positioning for the solenoid assembly 200. The guide sleeve 322 guides the solenoid assembly 200 into accurate position, avoiding radial offset of the solenoid assembly 200. This prevents media leakage caused by radial offset of the solenoid assembly 200 and improves the working reliability of the solenoid valve. The first limiting member 331 and the second limiting member 332 limit the mounting frame 321 from opposite sides of the axial direction, ensuring that the solenoid assembly 200 is fixed in the axial direction. This effectively prevents the solenoid assembly 200 from axially moving due to factors such as vibration and pressure changes during operation, ensuring the stability of the internal structure of the solenoid valve and improving the response speed and working accuracy of the solenoid valve.

[0034] Furthermore, the electromagnetic component 200 includes an electromagnetic coil 210 and a valve core 220. The electromagnetic coil 210 is wound around the outside of the mounting frame 321, and the valve core 220 is sleeved on the inside of the mounting frame 321. The valve core 220 passes through the mounting seat 310, and the mounting seat 310 is provided with a limiting step 311 that cooperates with the bottom of the valve core.

[0035] It should be noted that the mounting frame 321 serves as a support structure, ensuring that the electromagnetic coil 210 is tightly wound according to the designed position and shape, thereby resulting in a more uniform and concentrated magnetic field distribution. This uniform and concentrated magnetic field can act more precisely on the valve core, achieving effective driving of the valve core 220. The valve core 220 is fitted inside the mounting frame 321, which serves as a guide to ensure that the valve core 220 moves linearly in a predetermined direction under the action of electromagnetic force, preventing the valve core 220 from deviating or getting stuck during movement. The bottom of the valve core 220 passes through the mounting seat 310, which provides further positioning support for the valve core 220. The upper limit step 311 of the mounting seat cooperates with the bottom of the valve core 220. During assembly, the valve core 220 passes through the upper limit step 311 of the mounting seat, and the mounting seat 310 is then connected to the valve seat 100. Thus, the bottom of the valve core 220 is precisely limited within the connection space between the mounting seat 310 and the valve seat 100, realizing the rapid and accurate positioning and assembly of the valve core 220.

[0036] See Figure 3 , Figure 4 The mounting frame 321 includes a winding post 3211, an upper support plate 3212, and a lower support plate 3213. The winding post 3211 connects the upper support plate 3212 and the lower support plate 3213. The winding post 3211 is a hollow cylinder. An electromagnetic coil 210 is wound around the outside of the winding post 3211. A guide sleeve 322 is disposed inside the winding post 3211. The guide sleeve 322 includes an upper guide sleeve 3221 and a lower guide sleeve 3222. The upper guide sleeve 3221 is disposed in the upper part of the winding post 3211, and the lower guide sleeve 3222 is disposed in the lower part of the winding post 3211. The inner radial sides of the upper guide sleeve 3221 and the lower guide sleeve 3222 are radially engaged with the outer side of the valve core 220.

[0037] It should be noted that the structural design of the mounting frame 321 makes the installation and maintenance of the electromagnetic assembly 200 much simpler. The upper support plate 3212 and the lower support plate 3213 provide a stable mounting base for the electromagnetic assembly 200, while the winding post 3211 serves as the positioning reference for the electromagnetic coil 210 and the valve core 220. This design allows the electromagnetic assembly 200 to be quickly positioned and fixed during assembly, and also facilitates disassembly and replacement when needed. When the solenoid valve is energized, the electromagnetic coil 210 wound on the outside of the winding post 3211 of the mounting frame 321 forms a magnetic field after being energized, which generates an electromagnetic force on the valve core 220. The upper and lower support plates 3213 maintain the overall structural stability. The guide sleeve 322 inside the winding post 3211 is divided into upper and lower parts, which are placed in the upper and lower parts inside the winding post 3211, respectively. The inner radial side of the guide sleeve 322 is radially engaged with the outer radial side of the valve core 220. When the electromagnetic force drives the valve core 220 to move axially, the upper and lower guide sleeves 3222 provide precise guidance for the valve core 220, ensuring that the valve core 220 moves stably along a predetermined path, avoiding deviation or wobbling, and ensuring accurate engagement between the valve core 220 and the valve seat 100 for reliable opening and closing. At the same time, this engagement method reduces friction and wear between the valve core 220 and the guide sleeve 322, reducing energy loss and improving the operating efficiency and service life of the solenoid valve. Through this design, the solenoid valve can operate in a highly efficient and stable state, achieving rapid response and precise control to meet the needs of different operating conditions.

[0038] Furthermore, the winding post 3211 has an upper mounting position and a lower mounting position (not shown in the figure). The upper guide sleeve is fitted in the upper mounting position, and the lower guide sleeve is fitted in the lower mounting position. In this way, through the fitting structure, the upper and lower guide sleeves 3222 are precisely fixed in the designated axial position of the winding post 3211, ensuring that their mating surfaces with the valve core 220 are always at the designed height, avoiding deviation of the valve core 220's movement trajectory due to assembly errors, and preventing the valve core 220 from shaking or jamming. In addition, the upper and lower guide sleeves 3222 can be installed independently. During assembly, the lower guide sleeve 3222 is fixed first to provide bottom support for the valve core 220, and then the upper guide sleeve 3221 is fitted to complete the axial positioning. The assembly process is clear, requiring no additional tools, and only appropriate pressure is needed to complete the fixation, significantly shortening the assembly time and reducing the difficulty of operation. If a guide sleeve 322 is damaged, it can be disassembled and replaced individually, reducing maintenance costs.

[0039] See Figure 1 , Figure 5The first limiting member 331 includes an upper pressing plate 3311, a lower locking plate 3312, and a connecting plate 3313. The connecting plate 3313 connects the upper pressing plate 3311 and the lower locking plate 3312. The upper pressing plate 3311 and the lower locking plate 3312 have circular through holes coaxial with the winding post 3211. The part of the valve core 220 extending out of the guide sleeve 322 is fitted in the circular through hole. The upper pressing plate 3311 abuts against the upper support plate 3212. The lower locking plate 3312 has a first locking notch 3312a. The bottom surface of the lower support plate 3213 has a locking protrusion 3213a. The first locking notch 3312a and the locking protrusion 3213a are locked together. The connecting plate 3313 is provided with a terminal fixing seat 3314, the terminal fixing seat 3314 is connected to a wiring terminal 3315, the wiring terminal 3315 is snapped into the upper support plate 3212 and connected to the electromagnetic coil 210.

[0040] It should be noted that the aforementioned first limiting member 331 integrates the limiting function and electrical connection function. The upper pressing plate 3311 abuts against the upper support plate 3212, providing axial limiting for the valve core 220 and guide sleeve 322, preventing unnecessary displacement of the valve core 220 and guide sleeve 322 in the axial direction, and ensuring the stability of the internal structure of the solenoid valve. The lower locking plate 3312 engages with the locking protrusion 3213a on the bottom surface of the lower support plate 3213 through the first locking notch 3312a, further enhancing the structural stability, limiting the radial and axial sway of the valve core 220 and guide sleeve 322, and ensuring the accuracy of the valve core 220 during movement. The connecting plate 3313 is equipped with a terminal fixing seat 3314. The wiring terminal 3315 is inserted into the terminal fixing seat 3314 and snapped into the upper support plate 3212 for fixation. This allows the wiring terminal 3315 to be stably and easily connected to the solenoid coil 210 to conduct electricity to the external circuit, ensuring stable transmission of electrical signals. This design reduces the number of wiring components, simplifies the structure of the solenoid valve, reduces the risk of failure due to loose components or poor connections, and improves the overall reliability and stability of the solenoid valve.

[0041] During assembly, the upper guide sleeve 3221 is first fitted onto the upper mounting position of the winding post 3211, and the lower guide sleeve 3222 is fitted onto the lower mounting position. Then, the portion of the valve core 220 extending out of the guide sleeve 322 is fitted into the circular through holes of the upper pressing plate 3311 and the lower clamping plate 3312, so that the valve core 220, the guide sleeve 322, and the first limiting member 331 are initially assembled together. Next, the first clamping notch 3312a on the lower clamping plate 3312 is aligned with the clamping protrusion 3213a on the bottom surface of the lower support plate 3213, and the two are pressed firmly to make them securely clamped together. The first limiting member 331 is initially positioned in the axial and radial directions. Then, the position of the upper pressing plate 3311 is adjusted so that it is tightly abutted against the upper support plate 3212, thus completing the final axial positioning of the first limiting member 331. This ensures that the axial positions of the valve core 220 and the guide sleeve 322 are accurate. Finally, the wiring terminal 3315 is installed on the terminal fixing seat 3314 and fixed to the upper support plate 3212 of the mounting frame. At the same time, the lead wire of the electromagnetic coil 210 is connected to the connecting piece 3314a of the terminal fixing seat 3314 to achieve electrical connection.

[0042] Furthermore, the second limiting member 332 includes an upper pressing arm 3321, a lower locking arm 3322, and a connecting arm 3323. The connecting arm 3323 connects the upper pressing arm 3321 and the lower locking arm 3322. The upper pressing arm 3321 is pressed onto the mounting frame 321. The lower locking arm 3322 has a second locking notch 3322a, which is radially locked to the mounting base 310.

[0043] It should be noted that the upper pressing arm 3321, by pressing against the mounting frame 321, provides axial restraint for the mounting frame 321 and its connected components (such as the electromagnetic assembly 200). This prevents these components from moving upwards in the axial direction, ensuring the stability of the internal structure of the solenoid valve in the axial position and avoiding sealing failure or inaccurate movement between the valve core 220 and the valve seat 100 due to axial movement of the components. The lower locking arm 3322, through the second locking notch 3322a, radially engages with the mounting base 310, fixing the entire second limiting member 332 and its restrained components radially to the mounting base 310. This further helps ensure that the components do not wobble or shift in the radial direction, guaranteeing the radial accuracy of the valve core 220 during movement, allowing the valve core 220 to accurately engage with the valve seat 100 and achieve reliable opening and closing functions. That is, the second limiting member 332 tightly connects the mounting frame 321 and other components to the mounting base 310, forming a more stable overall structure. Together with the first limiting member 331, it bears the various forces and vibrations generated by the solenoid valve during operation, reduces the relative movement and loosening between components, and improves the overall reliability and service life of the solenoid valve.

[0044] See Figure 2In another embodiment, the mounting module 300 further includes a protective housing 400, which contains an electromagnetic component 200, a radial limiting component 320, and a first limiting member 331. The inner top side of the protective housing 400 abuts against the upper pressing plate 3311, and the outer top side of the protective housing 400 is provided with a pressing groove. The upper pressing arm 3321 is provided with a pressing arc piece 3321a, which is pressed onto the pressing groove. The bottom of the protective housing 400 is located between the snap-fit ​​plate and the mounting base 310.

[0045] It should be noted that the protective housing 400 effectively prevents these substances from entering the interior of the solenoid valve, avoiding dust and impurities from adhering to the surface of the solenoid component 200 or entering its internal precision structure, thus providing protection against dust and dirt. During operation, the protective housing 400 also helps the solenoid valve withstand external impacts, preventing deformation or displacement of the solenoid component 200 and protecting internal components such as the solenoid component 200 from damage, ensuring the normal operation of the solenoid valve. Furthermore, as shown in the figure, the upper pressing part of the second limiting member 332 is pressed against the top of the protective housing 400, and the lower locking part is radially locked to the mounting base 310. That is, the second limiting member 332 is entirely located outside the protective housing 400, and the "upper pressing and lower locking" method improves the structural stability between the protective housing 400 and the mounting base 310, thereby further improving the stability and reliability of the components enclosed within the protective housing 400.

[0046] See Figure 4 , Figure 6 The mounting base 310 includes a flange portion 312 and a threaded portion 313 connected to the flange portion 312. The end face of the flange portion 312 facing away from the threaded portion 313 is attached to the bottom of the protective housing 400. The lower snap-fit ​​arm 3322 is snapped under the flange portion 312. The threaded portion 313 is threadedly connected to the valve seat 100.

[0047] It should be noted that the design of the flange portion 312 on the mounting base 310 provides a stable support foundation for the entire mounting base 310. Preferably, it also clarifies the installation position relationship between the mounting base 310 and the protective shell 400, which helps maintain the stability of the entire solenoid valve assembly. The second limiting member 332 is snapped into the flange portion 312 below by the lower locking arm 3322, thus achieving a firm connection with the mounting base 310. Limited by the flange portion 312, it can withstand a certain amount of external force and vibration, ensuring that the lower locking arm 3322 and the flange portion 312 maintain a stable connection state during equipment operation, and are not easy to loosen or fall off, thereby ensuring the reliability of the connection between the entire mounting base 310 and other components. This greatly shortens the installation time and improves assembly efficiency. The connection between the mounting base 310 and the valve seat 100 adopts a threaded connection 313. When it is necessary to maintain, repair or replace parts of the solenoid valve, the threaded connection allows the mounting base 310 to be easily removed from the valve seat 100 without damaging other components, reducing maintenance costs and work difficulty.

[0048] Furthermore, a sealing ring (not shown in the figure) is provided between the bottom radial of the valve core 220 and the inner side of the mounting base 310.

[0049] It should be noted that during valve operation, the medium may flow in the gap between the bottom of the valve core 220 and the inner side of the mounting seat 310. The presence of the sealing ring can effectively fill these gaps, prevent medium leakage, and ensure that the valve can normally control the flow and cut off of the medium. Moreover, the sealing ring can play a buffering role, reduce the direct contact and friction between the valve core 220 and the mounting seat 310, reduce the wear of components, and extend the service life of the valve.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
