Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solenoid valves, and in particular to an intelligent memory type 2L solenoid valve. Background Art
[0002] Magnetic shape memory alloy is a composite material that can produce shape memory effect and magnetostrictive effect under the action of a magnetic field. This alloy can undergo martensitic phase transformation or reverse phase transformation under specific temperature or magnetic field conditions, thereby exhibiting unique shape memory and driving capabilities. With the development of technology, the research on using magnetic shape memory alloy, a new functional material, to manufacture a new generation of actuators has indeed attracted more and more attention. MSMA has shown great application potential in many fields with its excellent characteristics such as fast frequency response and high control precision. Magnetic shape memory alloy can also be used for solenoid valves.
[0003] Existing devices have some disadvantages during use. For example, the response speed of traditional solenoid valve actuators is relatively slow. The execution of the solenoid valve depends on the magnetization process of the electromagnet, that is, the current passes through the coil to generate a magnetic field, which in turn drives the valve core to move. This process takes a certain amount of time to complete, especially when the current increases from zero to a value sufficient to generate sufficient magnetic field strength. During this period, the response speed of the solenoid valve will be limited. Especially in situations where a fast response is required, such as emergency shut-off or rapid flow adjustment systems, this delay will have adverse consequences. Utility Model Content
[0004] The purpose of the utility model is to provide an intelligent memory type 2L solenoid valve to solve the problem of relatively slow response speed of traditional solenoid valve actuators.
[0005] The utility model provides the following technical solutions: an intelligent memory type 2L solenoid valve, comprising a valve body, the inner side of the valve body being fixedly connected to a valve seat boss, an inlet end and an outlet end being respectively provided at both ends of the valve body, an outer wall of one side of the valve body being fixedly connected to a shell, an installation cavity being provided inside the shell, a connecting hole being provided on the lower end surface of the shell, a fixing block being fixedly connected to the inner side of the connecting hole, a communicating hole being penetrated through the fixing block, an installation hole being provided at a position of the outer wall of one side of the valve body corresponding to the communicating hole, a sliding hole being provided in the top wall of the installing cavity, a lifting rod being slidably connected to the inner side of the sliding hole, the bottom end of the lifting rod vertically passing through the communicating hole and the installing hole and being slidably connected to the communicating hole, The outer side of the top of the lifting rod is fixedly sleeved with a lifting block, the outer side of the lifting rod is sleeved with a magnetically controlled shape memory alloy, and the magnetically controlled shape memory alloy is arranged between the lifting block and the fixed block, the outer side of the magnetically controlled shape memory alloy is sleeved with an electromagnetic coil, and the two ends of the electromagnetic coil are respectively fixedly connected to the inner top wall and the inner bottom wall of the mounting cavity, a controller is fixedly connected to the outer wall of one side of the shell, the bottom end of the lifting rod is fixedly connected to a valve core, and the valve core is slidably connected to the inner side of the mounting hole, the valve core is used in conjunction with the valve seat boss, the outer side of the lifting rod is sleeved with a first spring, and the first spring is arranged between the mounting block and the valve core, and a filter assembly is provided at the inlet end of the valve body.
[0006] In the above scheme, the precise control of the magnetically controlled shape memory alloy by the electromagnetic coil realizes highly intelligent and precise regulation of the fluid flow. The controller can adjust the current size according to demand, thereby accurately controlling the gap between the valve core and the valve seat boss, ensuring that the fluid flow meets the process requirements and improving the stability and efficiency of the production process. The rapid shape change of the magnetically controlled shape memory alloy under the action of the electromagnetic field enables the solenoid valve to complete the opening or closing action in a very short time, thereby improving the response speed of the system.
[0007] As a preferred embodiment of the above technical solution, the filter assembly includes a fixed hole opened at the inlet end of the valve body, four movable grooves opened in a horizontal array on the inner side of the fixed hole, the four movable grooves are provided with a rotation groove on the inner wall close to the valve core, and the four rotating grooves are provided with a clamping groove on the inner wall away from the valve core, and the four clamping grooves are connected to the corresponding movable grooves through the corresponding rotation grooves, and a filter mesh block is provided on the inner side of the fixed hole, and the positions of the four clamping grooves on the outer side of one end of the filter mesh block close to the valve core are fixedly connected with clamping blocks adapted to the size of the clamping grooves, and the filter mesh block is slidably connected to the fixed hole through the clamping block.
[0008] In the above solution, through the card connection design of the card block and the card slot, the filter mesh block can be firmly installed in the fixed hole, effectively preventing loosening or falling off due to fluid impact or vibration. This stability ensures the long-term stable operation of the solenoid valve system. The filter mesh block can effectively intercept impurities in the fluid. This filtering ability helps to protect other components of the solenoid valve system from being invaded by impurities and extend its service life.
[0009] As a preferred embodiment of the above technical solution, the filter assembly also includes an annular fixing groove annularly opened on the inner wall of one side of the fixing hole, and four placement holes are opened in an annular array on the inner wall of one side of the annular fixing groove, and a second spring is provided on the inner side of the four placement holes. The four second springs are fixedly connected to an annular spring plate at one end away from the placement hole, and the annular spring plate is slidably connected to the inner side of the annular fixing groove, and the end of the annular spring plate close to the filter mesh block conflicts with the filter mesh block.
[0010] In the above scheme, when the card block is aligned with the card slot, the second spring releases the compressed and stored elastic potential energy, and the generated elastic force is transmitted to the filter block through the annular spring plate. This elastic force causes the filter block to be pushed, thereby helping the card block to be more firmly stuck in the card slot. This design effectively prevents the filter block from loosening or falling off due to vibration or impact during use.
[0011] As a preferred embodiment of the above technical solution, the electromagnetic coil is electrically connected to the controller through an internal circuit.
[0012] In the above solution, the direct electrical connection between the electromagnetic coil and the controller ensures fast signal transmission and response. When the controller issues an instruction, the electromagnetic coil can respond quickly and achieve rapid opening or closing, thereby improving the response speed of the system.
[0013] As a preferred embodiment of the above technical solution, two sealing grooves are provided inside the communicating hole, and the two sealing grooves are arranged one above the other, and sealing rings are provided inside the two sealing grooves.
[0014] In the above solution, the two sealing rings fit tightly in the sealing groove and act together on the inner side of the communicating hole, thereby effectively preventing leakage of the medium (such as gas, liquid, etc.).
[0015] As a preferred embodiment of the above technical solution, flanges are fixedly sleeved on the outer sides of both ends of the valve body.
[0016] In the above solution, when the pipeline system needs to be maintained or parts need to be replaced, the connection between the valve body and other pipelines or equipment can be easily removed through the flange by simply loosening the bolts. This design reduces the complexity and time cost of maintenance work and improves work efficiency.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] In the present invention, by adjusting the current sent by the controller to the electromagnetic coil, the degree of shape change of the magnetically controlled shape memory alloy can be accurately controlled, and the size of the gap between the valve core and the valve seat boss can be fine-tuned. This fine-tuning capability enables the solenoid valve to achieve precise regulation of fluid flow and meet various complex process requirements. Compared with traditional solenoid valves, the magnetically controlled shape memory alloy solenoid valve has a faster response speed because the magnetically controlled shape memory alloy material can quickly produce shape changes under the action of a magnetic field, which helps to achieve more precise control in situations where rapid flow adjustment is required.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0026] Example
[0027] like Figure 1 、 Figure 2 and Figure 3As shown, the utility model provides a technical solution: an intelligent memory type 2L solenoid valve, including a valve body 10, a valve seat boss 11 is fixedly connected to the inner side of the valve body 10, an inlet end 12 and an outlet end 13 are respectively provided at both ends of the valve body 10, an outer wall on one side of the valve body 10 is fixedly connected to a shell 14, an installation cavity 15 is provided inside the shell 14, a connecting hole 16 is provided on the lower end surface of the shell 14, a fixing block 17 is fixedly connected to the inner side of the connecting hole 16, a connecting hole 18 is penetrated through the fixing block 17, a mounting hole 19 is provided at a position of the outer wall of one side of the valve body 10 corresponding to the connecting hole 18, a sliding hole 190 is provided on the top wall of the mounting cavity 15, a lifting rod 191 is slidably connected to the inner side of the sliding hole 190, and the bottom end of the lifting rod 191 vertically penetrates the connecting hole 18 and the mounting hole 19 And it is slidably connected with the connecting hole 18, the top outer side of the lifting rod 191 is fixedly sleeved with a lifting block 192, the outer side of the lifting rod 191 is sleeved with a magnetically controlled shape memory alloy 193, and the magnetically controlled shape memory alloy 193 is arranged between the lifting block 192 and the fixed block 17, the outer side of the magnetically controlled shape memory alloy 193 is sleeved with an electromagnetic coil 194, and the two ends of the electromagnetic coil 194 are respectively fixedly connected to the inner top wall and the inner bottom wall of the mounting cavity 15, and the outer wall of one side of the shell 14 is fixedly connected with a controller 195, the bottom end of the lifting rod 191 is fixedly connected with a valve core 196, and the valve core 196 is slidably connected to the inner side of the mounting hole 19, the valve core 196 is used in conjunction with the valve seat boss 11, and the outer side of the lifting rod 191 is sleeved with a first spring 197, and the first spring 197 is arranged at A filter assembly is provided at the inlet end 12 of the valve body 10 between the mounting block and the valve core 196. During specific use, when no power is applied, the electromagnetic coil 194 does not generate a magnetic field, and the magnetically controlled shape memory alloy 193 maintains its original shape. Due to the self-gravity of the valve core 196 and the elastic force of the first spring 197, the valve core 196 is pushed toward the valve seat boss 11 and fits tightly, thereby preventing the fluid from flowing from the inlet end 12 to the outlet end 13. When the controller 195 receives the opening signal, it sends current to the electromagnetic coil 194. The electromagnetic field generated by the electromagnetic coil 194 acts on the magnetically controlled shape memory alloy 193. Under the action of the electromagnetic field, the magnetically controlled shape memory alloy 193 extends upward along the axial direction of the lifting rod 191, driving the lifting rod 191 and the lifting block 192 to move upward. , the upward movement of the lifting rod 191 and the lifting block 192 drives the valve core 196 to leave the valve seat boss 11 to form a passage, allowing the fluid to flow in from the inlet end 12 and out through the outlet end 13. By adjusting the current sent by the controller 195 to the electromagnetic coil 194, the shape change degree of the magnetically controlled shape memory alloy 193 can be accurately controlled, and then the gap between the valve core 196 and the valve seat boss 11 can be adjusted, which allows the fluid flow to be accurately adjusted to meet different process requirements. When the controller 195 receives the closing signal, it cuts off the current of the electromagnetic coil 194, the magnetic field of the electromagnetic coil 194 disappears, and the magnetically controlled shape memory alloy 193 returns to its original shape. Under the action of the self-gravity of the valve core 196 and the elastic force of the first spring 197,The valve core 196 is pushed back toward the valve seat boss 11 and fits tightly together, thereby closing the fluid passage.
[0028] As an implementation method in this embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the filter assembly includes a fixed hole 20 opened at the inlet end 12 of the valve body 10, four movable grooves 30 arranged in a transverse array inside the fixed hole 20, a rotating groove 31 is opened on the inner wall of the four movable grooves 30 close to the valve core 196, and a clamping groove 32 is opened on the inner wall of the four rotating grooves 31 away from the valve core 196. The four clamping grooves 32 are connected to the corresponding movable grooves 30 through the corresponding rotating grooves 31. A filter mesh block 33 is provided inside the fixed hole 20, and the filter mesh block 33 is close to the valve core 196. The positions of the four card slots 32 corresponding to the outer side of one end are fixedly connected with card blocks 34 adapted to the size of the card slots 32, and the filter mesh block 33 is slidably connected to the fixed hole 20 through the card block 34. During specific use, the filter mesh block 33 is aligned with the fixed hole 20 so that the card block 34 is aligned with the movable slot 30, and the filter mesh block 33 is pushed to move it along the movable slot 30 toward the valve core 196. When the card block 34 moves to the position of the rotating slot 31, the filter mesh block 33 is rotated to move the card block 34 to the position of the card slot 32.
[0029] As an implementation method in this embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the filter assembly also includes an annular fixing groove 21 annularly opened on the inner wall of one side of the fixing hole 20, and four placement holes 22 are opened in an annular array on the inner wall of one side of the annular fixing groove 21. Second springs 23 are provided inside the four placement holes 22. One end of the four second springs 23 away from the placement holes 22 is fixedly connected to an annular spring plate 24, and the annular spring plate 24 is slidably connected to the inner side of the annular fixing groove 21. The end of the annular spring plate 24 close to the filter block 33 conflicts with the filter block 33. During specific use, when the filter block 33 is pushed and moves along the movable groove 30 toward the valve core 196, The annular spring plate 24 will be pushed by the filter block 33 to move, thereby compressing the second spring 23 connected to it. During this process, the second spring 23 stores elastic potential energy to prepare for the subsequent release of elastic force. When the blocking block 34 moves to the position of the rotating groove 31 and the filter block 33 is rotated to align the blocking block 34 with the blocking slot 32, the second spring 23 releases the compressed and stored elastic potential energy. During this process, the elastic force generated by the second spring 23 is transmitted to the filter block 33 through the annular spring plate 24. Therefore, the annular spring plate 24 is tightly pressed against the filter block 33, causing the blocking block 34 to be stuck in the blocking slot 32.
[0030] As an implementation method in this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the electromagnetic coil 194 is electrically connected to the controller 195 through internal circuits. During specific use, through the connection between the controller 195 and the electromagnetic coil 194, the operator can send a signal through the controller 195 at a location far away from the electromagnetic coil 194 to achieve remote control of the electromagnetic coil 194.
[0031] As an implementation method in this embodiment, Figure 5 As shown, two sealing grooves 40 are provided on the inner side of the connecting hole 18, and the two sealing grooves 40 are arranged up and down, and sealing rings 41 are provided on the inner side of the two sealing grooves 40. During specific use, the two sealing rings 41 can significantly enhance the sealing effect and reduce the risk of leakage. Even if one of the sealing rings 41 is worn or aged, the other sealing ring 41 can still maintain the sealing performance, thereby ensuring the stable operation of the system.
[0032] As an implementation method in this embodiment, Figure 1 and Figure 2 As shown, flanges 50 are fixedly sleeved on the outer sides of both ends of the valve body 10. During specific use, the design of the flange 50 makes the connection between the valve body 10 and other pipes or equipment tighter. The flange 50 is fastened together by fasteners such as bolts, which can effectively prevent fluid leakage and improve the sealing performance of the system.
[0033] Working principle: The valve body 10 is tightly connected to other pipes or equipment through the flange 50. The flange 50 is fastened together with bolts and other fasteners, which can effectively prevent fluid leakage and improve the sealing performance of the entire system. When not powered, the electromagnetic coil 194 does not generate a magnetic field, and the magnetically controlled shape memory alloy 193 maintains its original shape. The valve core 196 fits tightly on the valve seat boss 11 due to its own gravity and the elastic force of the first spring 197, preventing the flow of fluid. Align the filter block 33 with the fixed hole 20 on the valve body 10, ensure that the block 34 is aligned with the movable groove 30, and push the filter block 33 makes it move along the moving groove 30 toward the valve core 196. As the filter block 33 moves, the annular spring plate 24 is compressed, compressing the second spring 23 and storing elastic potential energy. When the block 34 reaches the position of the rotating groove 31, the filter block 33 is rotated so that the block 34 can smoothly enter the slot 32. At this time, the second spring 23 releases the stored elastic potential energy and tightly presses the filter block 33 through the annular spring plate 24 to ensure that the block 34 is firmly stuck in the slot 32. Through the connection between the controller 195 and the electromagnetic coil 194, the operator can send the switch at a location far away from the equipment. When the opening or closing signal is received, the controller 195 sends current to the electromagnetic coil 194 to generate an electromagnetic field, which in turn drives the magnetically controlled shape memory alloy 193 to extend axially upward along the lifting rod 191, driving the valve core 196 to leave the valve seat boss 11, forming a fluid passage. By adjusting the current sent by the controller 195 to the electromagnetic coil 194, the shape change degree of the magnetically controlled shape memory alloy 193 can be accurately controlled, thereby adjusting the gap between the valve core 196 and the valve seat boss 11. This precise gap control allows for fine adjustment of the fluid flow to meet To meet different process requirements, the two sealing rings 41 enhance the sealing effect and reduce the risk of leakage. Even if one of the sealing rings 41 is worn or aged, the other sealing ring 41 can still maintain the sealing performance to ensure the stable operation of the system. When the fluid passage needs to be closed, the controller 195 sends a closing signal to cut off the current of the electromagnetic coil 194. After the electromagnetic field disappears, the magnetically controlled shape memory alloy 193 returns to its original shape. Under the action of the valve core 196's own gravity and the elastic force of the first spring 197, the valve core 196 is pushed back to the valve seat boss 11 and fits tightly to prevent the fluid from flowing.
[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
