It is used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, speed regulating valves, etc.

[0003] For conventional pipelines that require fast on-off control, using a single electromagnetic component can only control the opening or fastness of the valve core, and cannot achieve fast on-off control. For this reason, there is a certain delay interval. This delay is particularly obvious on direct-acting solenoid valves. However, many pipeline structures can only use this type of solenoid valve due to space limitations. Therefore, there are certain defects in use.

[0039] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] like Figure 1 The dual-magnetic quick-cut solenoid valve device includes a valve body 1, which is characterized in that a control rod assembly is arranged in the valve body 1 to facilitate auxiliary driving. Considering the convenience of conduction control, an opening and closing assembly is arranged at the port of the valve body 1, and the opening and closing assembly is connected to the control rod assembly. At the same time, a buffer assembly is arranged between the opening and closing assembly and the control rod assembly to minimize the vibration between the opening and closing switching. In addition, the utility model is provided with a forward electromagnetic assembly 2 at the front end of the valve body 1, and a backward electromagnetic assembly 3 is arranged at the rear end of the valve body 1. Thus, the forward and backward movement of the control rod assembly can be driven respectively, and then the movement of the opening and closing assembly can be controlled to realize the opening and closing switching inside the whole valve. In order to avoid unnecessary electromagnetic dry burning during operation and allow the control rod assembly to be displaced better, an electromagnetic retaining ring 4 is distributed between the forward electromagnetic assembly 2 and the backward electromagnetic assembly 3. The opening and closing assembly adopted by the utility model includes a valve core 5 connected to the buffer assembly, and also includes a valve sleeve 6 connected to the port of the valve body 1, and the valve core 5 is located in the valve sleeve 6. During assembly, the valve sleeve 6 is threadedly connected to the valve body 1, and some screw glue is added at the joint. Furthermore, in order to realize convenient on-off switching control, a plurality of inlet holes 7 are distributed on the valve sleeve 6, and a plurality of diversion holes 8 are distributed on the valve core 5. Therefore, when in the locked state, the positions of the inlet holes 7 and the diversion holes 8 are staggered, and they are in a non-conductive state. When in the unlocked state, at least one group of inlet holes 7 is aligned with the diversion holes 8 to allow the liquid to flow through.

[0041] In view of a preferred embodiment of the utility model, the control rod assembly includes a moving iron core 9, a guide rod 10 is provided at the front end of the moving iron core 9, and a bearing base 11 is sleeved on the guide rod 10. At the same time, considering the buffering needs during use, a buffer cavity is provided in the bearing base 11, and a buffer assembly is provided in the buffer cavity. In addition, in order to have a better guiding fault tolerance effect, the buffer cavity is provided with a contact expansion 12. In this way, even if the buffer assembly is in an extreme pressure state, when it is released, one end thereof can still follow the guidance of the contact expansion 12 and enter the buffer cavity.

[0042] Further, the buffer assembly used in the utility model includes a buffer rod 13 connected to the control rod assembly bearing base 11. A spring 14 is provided on the outer sleeve of the buffer rod 13, and the buffer rod 13 contacts the valve core 5. At the same time, the valve core 5 is provided with a bearing pad 15 in contact with the spring 14. In this way, the end of the spring 14 can be stably contacted, ensuring that the end of the spring 14 will not be skewed due to deformation and expansion, and a smooth release and reset can be achieved.

[0043] In view of the actual implementation, both the forward electromagnetic assembly 2 and the backward electromagnetic assembly 3 include an assembly housing 16, which is used to achieve insulation protection and can also effectively prevent the intrusion of external foreign matter. Taking into account the convenience of assembly and combination, a valve body 1 combination channel is reserved in the assembly housing 16, which can be directly passed forward and backward during assembly. At the same time, a coil module 17 is provided in the assembly housing 16, and a wiring terminal 18 is conductively connected to the coil module 17. In addition, a sealing sleeve (not shown in the figure) is provided outside the wiring terminal 18. In this way, the drive line can be docked with the wiring terminal 18 during use, and the sealing sleeve can be used to improve the sealing of the interface to prevent the inflow of external foreign matter.

[0044] Further, in order to achieve stable combination with the subsequently installed pipeline, a plurality of contact guide rings 19 with decreasing diameters from the inside to the outside are distributed outside the valve sleeve 6. The actual distribution interval of the contact guide rings 19 can be adapted to the limit step inside the pipeline. At the same time, a receiving groove is provided in the contact guide ring 19, and a contact sealing ring 20 is provided in the receiving groove. In this way, it can better seal and flexibly contact with the inner wall of the connecting pipeline to avoid resonance and abnormal sound during use.

[0045] At the same time, considering that when the utility model is combined with a preset pipeline, there may be a certain tolerance gap due to the combination slope reserved for the pipeline, a combination groove can be provided at the port of the valve body 1, and a combination sealing ring 21 is provided in the combination groove. In this way, through the cooperation of the combination sealing ring 21 and the external locking mechanism, the utility model can be ensured to be stably and tightly combined with the pipeline.

[0046] During implementation, a travel limit seat 22 can be provided in the tail end of the valve body 1. In this way, by selecting different travel limits, the movable travel of the moving iron core 9 can be limited. In this way, it is controlled whether the inlet hole 7 and the diversion hole 8 can be fully aligned, and the actual flow control during conduction is realized. Different conduction schemes are provided for pipelines that do not use hydraulic pressure or medium, which reduces the overall manufacturing implementation cost.

[0047] Furthermore, a locking nut 23 is provided at the tail end of the valve body 1, and a limiting gasket 24 is provided at the front end of the valve body 1. After assembly, the retracting electromagnetic assembly 3 is in contact with the locking nut 23, and the forward electromagnetic assembly 2 is in contact with the limiting gasket 24. Moreover, the locking nut 23 and the limiting gasket 24 can be combined with the valve body 1 in a threaded manner. In this way, the assembly can be completed conveniently, and the gap adjustment can be conveniently realized, so that the retracting electromagnetic assembly 3 is clamped by the locking nut 23 and the electromagnetic retaining ring 4. At the same time, the forward electromagnetic assembly 2 is clamped by the electromagnetic retaining ring 4 and the limiting gasket 24. Avoid unnecessary displacement of the forward electromagnetic assembly 2 and the reverse electromagnetic assembly 3 during use, and reduce the possibility of resonance and abnormal noise. Furthermore, for some special compact limit needs, the locking nut 23 and the limiting gasket 24 can move toward each other to achieve better clamping and locking of the forward electromagnetic assembly 2 and the reverse electromagnetic assembly 3.

[0048] The working principle of the utility model is as follows:

[0049] In the default working state, the buffer component is in the released state, and the forward electromagnetic component 2 and the backward electromagnetic component 3 are both in the standby state. At this time, the pipeline to be controlled is in a blocked state, and the liquid flow cannot be connected to the next section of the pipeline through the opening and closing component.

[0050] When conduction and diversion are required, the backward electromagnetic assembly 3 is operated, and the forward electromagnetic assembly 2 is on standby, and the moving iron core 9 is sucked backward. At the same time, the valve core 5 is driven to move backward. As a result, at least one set of inlet holes 7 is aligned with the diversion holes 8 to achieve conduction of the passage. At the same time, the buffer assembly is in a stretched state. It should be noted that according to the actual needs of conduction and diversion, one or more sets of inlet holes 7 can be selected to be aligned with the corresponding diversion holes 8 to increase the conduction capacity. This can be achieved by selecting valve cores 5 and valve sleeves 6 of corresponding specifications during manufacturing, which will not be repeated here.

[0051] When it is necessary to close, the forward electromagnetic assembly 2 operates and the backward electromagnetic assembly 3 is on standby. At this time, the moving iron core 9 moves forward and the buffer assembly is reset to prevent the moving iron core 9 from causing excessive impact on the valve core 5 during the movement. Afterwards, the inlet hole 7 and the guide hole 8 are misaligned, and the currently controlled pipeline flow cannot pass.

[0052] It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:

[0053] 1. The forward electromagnetic assembly and the backward electromagnetic assembly can realize the rapid position switching of the moving iron core, thereby realizing the rapid opening and closing of the valve, with a short response time and improved flow control accuracy.

[0054] 2. Equipped with a buffer component to avoid collision with the valve core and extend its service life.

[0055] 3. The number and position of inlet holes and diversion holes can be customized to achieve different liquid flow control.

[0056] 4. A travel limit seat can be added to achieve the alignment adjustment of the inlet hole and the diversion hole.

[0057] 5. The forward electromagnetic component and the backward electromagnetic component are firmly combined and will not cause resonance.

[0058] 6. The overall structure is simple and can be matched with the current conventional valve body or locking structure, and is easy to use and maintain.

[0059] In addition, the indicated orientations or positional relationships described in the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure. Therefore, they cannot be understood as a limitation on the present invention.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
