Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of electromagnetic valve technology, and specifically to an electromagnetic valve. Background Technology
[0002] A solenoid valve generally includes a valve sleeve assembly, a solenoid valve housing, a solenoid tube, and other features. The solenoid tube has a connector on its outer periphery and a coil inside, forming an integral unit with the front yoke. When the coil is energized, it can form a complete electromagnetic circuit, providing the required electromagnetic force for the axial movement of the armature and ensuring that the movement of the armature meets the design requirements.
[0003] The valve sleeve assembly is fixed between the housing and the solenoid. The bottom of the solenoid has a groove, and the contact part between the valve sleeve assembly and the solenoid has a flange. The housing has a through hole with the same structure as the bottom of the solenoid, so that the valve sleeve assembly can pass through the through hole for assembly of the solenoid valve.
[0004] During assembly, the flange of the current solenoid valve passes through the through hole at the front end of the housing. By rotating the flange, the valve sleeve component is axially limited and cannot move. At the same time, the solenoid tube is installed from the rear end of the housing. The groove at the end of the solenoid tube fits with the flange of the valve sleeve component to prevent the valve sleeve component from rotating radially. In this way, the valve sleeve component is fixed and its movement is prevented from both axial and radial directions.
[0005] The above solution increases the processing technology of the outer shell, indirectly increasing the cost of the outer shell. Furthermore, the use of irregular shapes for the through holes in the outer shell increases the processing difficulty of the outer shell.
[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content
[0007] 1. The technical problem to be solved by the utility model:
[0008] This utility model provides a solenoid valve to solve the technical problems existing in the background art.
[0009] 2. Technical Solution:
[0010] To achieve the above objectives, the technical solution provided by this utility model is: a solenoid valve, comprising...
[0011] A valve sleeve assembly, wherein a valve core is provided inside the valve sleeve assembly and an irregularly shaped connecting block is provided at one end;
[0012] A protective housing with a through hole, the through hole being matched and connected to the valve sleeve component, the maximum length of the irregular connecting block being greater than the diameter of the through hole;
[0013] An electromagnetic component, one end of which has a shaped groove, which engages with the shaped connecting block.
[0014] During assembly, the valve sleeve component is inserted into the groove of the protective housing. Due to the obstruction of the irregular connecting block, the irregular connecting block of the valve sleeve component will be located inside the groove of the protective housing, while the rest of the component passes through the through hole of the protective housing. Then, the electromagnetic component is inserted into the groove of the protective housing, ensuring that the irregular connecting block is located in the irregular groove, thus restricting the rotation of the valve sleeve component. This ensures that the valve sleeve component, the protective housing, and the electromagnetic component form a whole and do not move, thereby completing the assembly. The protective housing of this solenoid valve is provided with a standard through hole, which reduces the difficulty of its manufacturing.
[0015] Furthermore, the irregular connecting block includes a first direction and a second direction, wherein the first direction is shorter in axial dimension than the second direction, the second direction has an axial dimension greater than the diameter of the through hole, and a locking step is provided at the end where the irregular groove intersects with the irregular connecting block.
[0016] Furthermore, the protective housing has a clearance groove, and the electromagnetic component has a connector on its side, with the clearance groove corresponding to the position of the connector.
[0017] Furthermore, the protective shell has a concave groove at its end, which engages with the protective plate, and the convex portion of the concave groove can be bent inward.
[0018] Furthermore, the valve sleeve component has an adjustment hole at its end, the adjustment hole is threaded to a spring seat, the outer side of the spring seat has a rotating groove, the inner side of the spring seat abuts against one end of the adjustment spring, and the other end of the adjustment spring is matched and connected to the valve core.
[0019] Furthermore, the rotating groove adopts a cross-shaped slot.
[0020] Furthermore, fastening screws are riveted to the corresponding positions on the outer end of the valve sleeve component.
[0021] Furthermore, the electromagnetic component has a coil inside, the coil has a sliding space inside, and the sliding space has a sliding armature. The side of the armature is connected to one end of the push rod, and the other end of the push rod is connected to the valve core. The push rod has intersecting radial flow holes and axial flow holes.
[0022] Furthermore, both the radial flow hole and the axial flow hole are circular holes.
[0023] 3. Beneficial effects:
[0024] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0025] This utility model has a reasonable design. The circular groove on the protective shell reduces the manufacturing difficulty of the protective shell and can limit and protect the valve sleeve and solenoid components, making the solenoid valve assembly process simpler, simplifying the protective shell processing process, and reducing production and assembly costs.
[0026] By setting a rotatable and movable spring seat, the process of selecting spring seats and springs is eliminated, simplifying the process flow. At the same time, it ensures that the solenoid valve assembly and production process is more stable and reliable, with a higher pass rate. Using a threaded assembly method, if the performance of the solenoid valve needs to be adjusted, the installation depth of the spring seat inside the valve sleeve component is adjusted using special tools until the performance of the solenoid valve meets the design requirements. Finally, the spring seat is fixed to the valve sleeve by riveting to fix the position of the spring seat and prevent loosening during later operation, which would require adjustment of the screw-in depth and prevent the performance of the solenoid valve from deviating.
[0027] The push rod is equipped with radial and axial flow holes, both of which are circular. These flow holes connect the two spaces before and after the armature, serving to allow for air and oil passage, preventing impact and fluid resistance during armature movement that could hinder its smooth operation. This design simplifies the push rod's manufacturing process, reduces costs, and significantly lowers the difficulty of quality control.

[0041] It should be noted that structures not described in this invention do not involve the design points and improvement directions of this invention, and can all be achieved using existing technologies known to those skilled in the art. Example
[0042] See attached document Figure 1-6 A solenoid valve, including
[0043] Valve sleeve component 1, wherein a valve core 2 is provided inside the valve sleeve component 1 and an irregularly shaped connecting block 3 is provided at one end;
[0044] The protective housing 4 has a through hole 5, which is matched and connected to the valve sleeve component 1. The maximum length of the irregular connecting block 3 is greater than the diameter of the through hole 5.
[0045] Electromagnetic component 6, one end of which has an irregular groove 7, which is engaged with the irregular connecting block 3.
[0046] During assembly, the valve sleeve component 1 is inserted into the groove of the protective housing 4. Due to the obstruction of the irregular connecting block 3, the irregular connecting block 3 of the valve sleeve component 1 will be located inside the groove of the protective housing 4, while the rest of the component passes through the through hole 5 of the protective housing 4. Then, the electromagnetic component 6 is inserted into the groove of the protective housing 4, ensuring that the irregular connecting block 3 is located in the irregular groove 7, thus restricting the rotation of the valve sleeve component 1. This ensures that the valve sleeve component 1, the protective housing 4, and the electromagnetic component 6 form a whole and do not move, thereby completing the assembly. The protective housing 4 of this solenoid valve is provided with a standard through hole 5, which reduces the difficulty of its manufacturing.
[0047] Please refer to this carefully. Figure 2 The irregular connecting block 3 includes a first direction 31 and a second direction 32, wherein the first direction 31 is shorter in axial dimension than the second direction 32, and the axial dimension of the second direction 32 is larger than the diameter of the through hole 5. The end of the irregular groove 7 that intersects with the irregular connecting block 3 is provided with a locking step 71. When the valve sleeve component 1 is fitted into the protective shell 4, the valve sleeve component 1 will be restricted inside the protective shell 4 because the axial dimension of the second direction 32 is larger than the diameter of the through hole 5. When the electromagnetic component 6 at the rear end is inserted into the protective shell 4, the irregular connecting block 3 and the locking step 71 of the irregular groove 7 are engaged, which can limit the valve sleeve component 1.
[0048] Please refer to this carefully. Figure 5 and Figure 6 The protective housing 4 has a clearance groove 41, and the electromagnetic component 6 has a connector 67 on its side. The clearance groove 41 and the connector 67 are positioned opposite each other, and the clearance groove 41 facilitates the installation of the electromagnetic component 6.
[0049] Please refer to this carefully. Figure 5 and Figure 6 The protective shell 4 has a concave groove 42 at its end, which engages with the protective plate 43. The convex portion of the concave groove 42 can be bent inward. When the protective shell 4 encloses all components, it is necessary to protect and fix all internal structures. Therefore, the protective plate 43 can be placed in the concave groove 42. Then, a bending device is used to bend the end of the protective shell 4 inward, thereby limiting the position of the protective plate 43.
[0050] Please refer to this carefully. Figure 1 and Figure 6 The valve sleeve component 1 has an adjustment hole 11 at one end, and the adjustment hole 11 is threadedly connected to a spring seat 12. The outer side of the spring seat 12 is provided with a rotating groove 13, and the inner side of the spring seat 12 abuts against one end of an adjusting spring 14. The other end of the adjusting spring 14 is matched and connected to the valve core 2. The valve sleeve component 1 can adjust the elastic force of the adjusting spring 14 by moving the position of the spring seat 12, thereby adjusting the pressure requirement of the solenoid valve core 2. The adjustment is very convenient. This processing and assembly method has lower cost and is more convenient to operate. There is no process of selecting the spring seat 12 and spring, which simplifies the process flow. At the same time, it ensures that the solenoid valve assembly and production process is more stable and reliable, and the pass rate is higher. With the threaded assembly method, if the performance of the solenoid valve needs to be adjusted, the installation depth of the spring seat 12 inside the valve sleeve is adjusted by special tools until the performance of the solenoid valve meets the design requirements.
[0051] Please refer to this carefully. Figure 4 and Figure 6 The rotating groove 13 adopts a cross-shaped groove, which is convenient for adapting to the tool to adjust the depth of the spring seat 12. It should be noted that the cross-shaped groove can also adopt other grooves of any shape, as long as the spring seat 12 can rotate normally under the use of the corresponding tool.
[0052] The valve sleeve component 1 is riveted to a corresponding position on its outer end. The fastening screw is driven directly into the valve sleeve component 1 from the outside of the spring seat 12 position, thereby fixing the spring seat 12 to the valve sleeve by riveting. This fixes the position of the spring seat 12 and prevents it from loosening during later operation, which would cause the screwing depth to need adjustment and prevent the performance of the solenoid valve from deviating.
[0053] Please refer to this carefully. Figure 1The electromagnetic component 6 contains a coil 61, which in turn contains a sliding space 62. A sliding armature 63 is located within the sliding space 62. The side of the armature 63 is connected to one end of a push rod 64, and the other end of the push rod 64 is connected to the valve core 2. The push rod 64 has intersecting radial flow holes 65 and axial flow holes 66. When the position of the valve core 2 needs to be adjusted, the coil 61 is energized. Due to electromagnetic induction, the armature 63 slides within the sliding space 62, thereby moving the push rod 64. Finally, the push rod 64 moves the valve core 2 to control the valve's opening and closing. The intersecting radial flow holes 65 and axial flow holes 66 connect the two spaces before and after the armature 63, serving the purpose of air and oil passage. Of course, there are other components in the device, all of which are existing structures of electromagnetic valves and will not be described in detail here.
[0054] Please refer to this carefully. Figure 3 Furthermore, both the radial flow hole 65 and the axial flow hole 66 are circular holes. It should be noted that the two flow holes can be vent holes of other shapes, as long as they do not affect the internal gas and liquid flow.
[0055] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this 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 modifications and improvements 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.
