[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0031] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 11 As shown, the embodiment of the present application discloses a valve, which includes a first cylinder 100, a second cylinder 200, an action part 300 and a magnet 400. The above-mentioned valve can be installed in a pipeline to control the on-off of the fluid in the pipeline on both sides of the valve through the valve. Among them, the first cylinder 100 and the second cylinder 200 can be made of materials with relatively high structural strength such as metal or plastic, and the action part 300 is a magnetic structural part, that is, the action part 300 is made of magnetic material, such as the action part 300 can be made of at least one of metal iron, metal cobalt and metal nickel, to ensure that the action part 300 can be attracted by the magnet 400, thereby ensuring that the magnet 400 can apply an attractive force to the action part 300.

[0033] The first barrel 100 includes a barrel body 110 and a mounting portion 120. The barrel body 110 is provided with an inner cavity and a first channel 111, and the inner cavity and the first channel 111 are connected to each other. The inner cavity is located on the inner side of the first channel 111. Specifically, the barrel body 110 is an annular structure. The interior of the barrel body 110 is provided with an inner cavity with a cylindrical structure, and the outer side of the inner cavity is provided with the first channel 111, and the first channel 111 is connected to the inner cavity.

[0034] The mounting portion 120 is located in the inner cavity, and the mounting portion 120 is sealed and connected to the inner wall of the inner cavity. Specifically, the mounting portion 120 as a whole can be a cylindrical structural member, and the mounting portion 120 can be bonded and fixed to the inner wall of the inner cavity by welding or bonding, so that the mounting portion 120 forms a fixed relationship with the cylinder body 110, and can ensure that the mounting portion 120 forms a sealed relationship with the inner wall of the inner cavity.

[0035] Meanwhile, the mounting portion 120 is provided with a second channel 122 and a first opening, the first channel 111 and the second channel 122 both extend along the axial direction of the barrel body 110, and the second channel 122 and the first channel 111 are spliced ​​and arranged, so that after the mounting portion 120 is installed in the inner cavity, the second channel 122 can form a complete channel with the first channel 111, of course, the second channel 122 in the mounting portion 120 is located between the barrel body 110, and no sealing matching relationship is formed. In addition, one end of each of the first channel 111 and the second channel 122 is communicated with the first side of the mounting portion 120 away from the inner cavity, that is, the first channel 111 and the second channel 122 both extend to the end surface of the first side of the mounting portion 120 away from the inner cavity, thereby ensuring that the fluid in the pipeline connected to the valve can provide a force to the action portion 300 located in the first channel 111 and the second channel 122. Of course, in order to ensure that the action part 300 does not move from the first channel 111 and the second channel 122 to the outside of the valve, the size of the position where the first channel 111 and the second channel 122 are connected to the end surface of the first side of the mounting part 120 can be made relatively small, or a mesh plate or mesh can be set at the ends of the first channel 111 and the second channel 122.

[0036] At the same time, the other end of the second channel 122 and the first opening are both connected to the inner cavity, so that after the fluid in the pipeline connected to one side of the valve flows into the inner cavity, it can flow out to the other side of the valve through the first opening and the second channel 122. Specifically, the second channel 122 and the inner cavity are distributed along the axial direction of the barrel body 110, and along the radial direction of the barrel body 110, a part of the first channel 111 is located outside the second channel 122, and another part of the first channel 111 is located outside the inner cavity.

[0037] The second cylinder 200 is provided with a second opening 210 and a third channel 220, and the second opening 210 runs through the second cylinder 200 along the axial direction of the cylinder body 110, that is, the space on the opposite sides of the second cylinder 200 can be communicated by the second opening 210. At the same time, the second cylinder 200 is located in the inner cavity, and the end face of the second cylinder 200 is sealed with the end face of the second side of the mounting portion 120 away from the first side, so that the space on one side of the second cylinder 200 away from the mounting portion 120 and the space on the one side of the mounting portion 120 away from the second cylinder 200 can only be mutually connected when the second opening 210 on the second cylinder 200 is opposite to the first opening on the mounting portion 120. Specifically, the end face of one of the second cylinder 200 and the mounting portion 120 facing the other can be mutually fitted, so that the fluid on the opposite sides of the valve will not flow through the gap between the second cylinder 200 and the mounting portion 120, ensuring that the valve has reliable sealing performance.

[0038] Furthermore, the third channel 220 on the second cylinder 200 extends in an axial spiral around the cylinder body 110 from one end of the second cylinder 200 close to the mounting portion 120, that is, the third channel 220 is a spiral channel, and one end of the third channel 220 extends to an end surface of the second cylinder 200 close to the mounting portion 120, which enables the third channel 220 to be docked with the second channel 122, so that the action portion 300 can switch between the combined space formed by the first channel 111 and the second channel 122, and the combined space formed by the first channel 111 and the third channel 220. Of course, in order to ensure that the valve has the ability to block the space on both sides of the valve, the cross-sectional shape of the action part 300 can be made the same as the cross-sectional shape of the combined space formed by the first channel 111 and the third channel 220, and by making the cross-sectional size of the action part 300 slightly smaller than the cross-sectional size of the aforementioned combined space, it can be ensured that the action part 300 has the ability to move between the second channel 122 and the third channel 220, and it can also be ensured that the action part 300 can basically block the combined space formed by the first channel 111 and the third channel 220 (as well as the first channel 111 and the second channel 122). It should be noted that since the action part 300 has the ability to move in the third channel 220, even if the action part 300 is located in the third channel 220, there may be a small amount of fluid flowing on the opposite sides of the action part 300. Considering that the order of magnitude between the aforementioned flow rate and the flow rate when the valve is open is very different, when the action part 300 is located in the third channel 220, it can be approximately considered that the action part 300 can block the combined space formed by the first channel 111 and the third channel 220.

[0039] Furthermore, since the third channel 220 is a spiral channel, during the movement of the action part 300 along the third channel 220, the action part 300 is restricted by the first channel 111 extending along the axial direction of the barrel body 110, so that the action part 300 can drive the second barrel body 200 to rotate relative to the barrel body 110. Furthermore, during the relative rotation of the second barrel body 200 and the first barrel body 100, the relative position between the first opening and the second opening 210 can be changed. When the first opening and the second opening 210 are in a state of relative arrangement, the spaces on the opposite sides of the valve can be communicated with each other through the first opening and the second opening 210, so that the valve is in an open state.

[0040] Of course, in order to ensure that the first opening and the second opening 210 have the ability to be isolated from each other and to be connected to each other during the rotation of the second cylinder 200, the first opening and the second opening 210 are each required to be located on one side of the straight line where the diameter of the first cylinder 100 is located, and the angle spanned by the first opening and the second opening 210 is required to be less than or equal to 180°. Optionally, the first opening and the second opening 210 can both be circular holes or rectangular holes, etc., and by making the positions of the first opening and the second opening 210 correspond to each other, it can be ensured that the first opening and the second opening 210 are connected to each other after the second cylinder 200 rotates through a preset angle.

[0041] At least one of the first barrel 100 and the second barrel 200 is provided with a magnet 400, and the magnet 400 is located on the side of the second side away from the first side. Specifically, the magnet 400 can be arranged on the first barrel 100 or the second barrel 200, or the first barrel 100 and the second barrel 200 can be provided with a magnet 400, and the installation position of the magnet 400 is close to the position of the inner cavity, and is located on the side of the second side away from the first side in the installation part 120, that is, the side where the second barrel 200 is located. And, as described above, the action part 300 is a magnetic structural part, and the action part 300 can switch with each other in the combined space composed of the first channel 111 and the second channel 122, and in the combined space composed of the first channel 111 and the third channel 220.

[0042] Based on this, after the above-mentioned valve is installed in the pipeline, when the pressure of the fluid on opposite sides of the pipeline is different, the fluid in the pipeline can pass through the first channel 111 and the second channel 122, as well as the second channel 122 and the third channel 220, to apply a force to the action part 300, and the magnet 400 will also apply a force to the action part 300. Under the action of the above-mentioned two external forces, the action part 300 can move in the combined space formed by the first channel 111 and the second channel 122, as well as the combined space formed by the second channel 122 and the third channel 220, thereby driving the second cylinder 200 to reciprocate relative to the first cylinder 100.

[0043] More specifically, since the third channel 220 is a spiral channel, the direction of the driving force of the fluid in the space connected to the valve acting on the actuating part 300 is the tangent direction of the actuating part 300 in the third channel 220, and the direction of the driving force of the magnet 400 acting on the actuating part 300 is the direction of the line connecting the center of the magnet 400 and the center of the actuating part 300, and the directions of the components of the two driving forces in the axial direction of the cylinder body 110 are opposite. Furthermore, when the component of the driving force of the fluid in the axial direction of the barrel body 110 is greater than the component of the driving force of the magnet 400 in the aforementioned direction, the action part 300 can be driven to overcome the driving force of the magnet 400 and move along the third channel 220 in a direction away from the magnet 400, and finally move into the second channel 122; on the contrary, the action part 300 overcomes the driving force of the fluid under the action of the magnet 400 and moves along the second channel 122 in a direction close to the magnet 400, and finally moves to the position where the magnet 400 is located through the third channel 220, so as to achieve the purpose of resetting the action part 300. It should be noted that in the present application, since the order of magnitude of the driving force of the fluid and the driving force of the magnet 400 is much greater than the gravity of the action part 300 and the friction force when the action part 300 moves, in order to facilitate the introduction of the movement of the action part 300, only the driving force of the fluid and the magnet 400 acting on the action part 300 is considered.

[0044] When the action part 300 is located in the first position, the action part 300 is located in the first channel 111 and the second channel 122, and as mentioned above, the action part 300 has the ability to block the combined structure of the first channel 111 and the second channel 122. At this time, the projection of the second opening 210 along the axial direction of the cylinder body 110 is still outside the first opening. Since the end faces of the second cylinder body 200 and the mounting part 120 are sealed with each other, when the first opening and the second opening 210 are in the above state, it can be ensured that the first opening and the second opening 210 are isolated from each other, and the spaces on the opposite sides of the valve can neither be communicated with each other through the first channel 111 (and the second channel 122 and the third channel 220), nor can they be communicated with each other through the first opening and the second opening 210, which can ensure that the valve is in a closed state.

[0045] When the action part 300 is located at the second position, the action part 300 is located in the first channel 111 and the third channel 220, and the action part 300 blocks the first channel 111 and the third channel 220, so that the space where the action part 300 is located does not provide the function of a connecting space at all times, and only moves under the action of the fluid on the opposite sides of the action part 300 to drive the second cylinder 200 to rotate relative to the first cylinder 100, thereby changing the relative position between the first opening and the second opening 210, so that after the action part 300 moves from the first position to the second position, the axial projection of the second opening 210 along the cylinder body 110 is located within the first opening, ensuring that the second opening 210 can be connected with the first opening, so that the fluid on one side of the valve can flow to the other side of the valve through the second opening 210 and the first opening.

[0046] The present application discloses a valve, which includes a first cylinder 100, a second cylinder 200, an action part 300 and a magnet 400. The first cylinder 100 includes a cylinder body 110 and a mounting part 120. The cylinder body 110 is provided with an inner cavity and a first channel 111. The mounting part 120 is provided with a first opening and a second channel 122. The second cylinder 200 is arranged in the inner cavity. The second cylinder 200 is provided with a second opening 210 and a third channel 220. At least one of the first barrel 100 and the second barrel 200 is provided with a magnet 400, which can attract the action part 300, and after the valve is installed on the pipeline, when there is fluid in the pipeline, the action part 300 will also be subject to the driving force applied by the fluid in the pipeline, and under the combined action of the magnetic driving force of the aforementioned magnet 400 and the driving force of the fluid (the magnitude may be zero), the action part 300 can move in the combined space composed of the first channel 111 and the second channel 122, and in the combined space composed of the first channel 111 and the third channel 220. And, when the axial force component of the driving force of the fluid in the barrel body 110 is greater than the force component of the driving force of the magnet 400 in the aforementioned direction, the action part 300 moves from the third channel 220 to the second channel 122, and vice versa, the action part 300 moves from the second channel 122 to the third channel 220. Since the third channel 220 is a spiral structure and the first channel 111 extends along the axial direction of the cylinder body 110, the second cylinder 200 can be driven to rotate relative to the first cylinder 100 during the movement of the action part 300 along the third channel 220, and the relative position between the second opening 210 on the second cylinder 200 and the first opening on the first cylinder 100 can be changed, so that the second opening 210 and the first opening are switched between mutually isolated and mutually connected states, so that the valve has the ability to close and open, and the switching of the valve between the closed state and the open state depends on the pressure difference between the fluids on the opposite sides of the valve, so that the opening and closing state of the valve can be changed without manual intervention, and the valve has a high degree of automation.

[0047] In order to improve the efficiency of the valve when switching from the closed state to the open state, optionally, the valve disclosed in the embodiment of the present application also includes a blade 510 and a connecting shaft 520, the connecting shaft 520 is fixedly connected to the second cylinder 200, and the axis of the connecting shaft 520 is colinear with the axis of the second cylinder 200, so that when the action part 300 moves along the third channel 220 and drives the second cylinder 200 to rotate relative to the first cylinder 100, the second cylinder 200 can drive the rotating shaft to rotate coaxially. At the same time, the blade 510 is connected to the connecting shaft 520, and based on the rotation direction of the second cylinder 200, the tortuous form of the blade 510 is designed, so that in the process of the action part 300 switching from the first position to the second position, the fluid flowing to the second opening 210 can drive the blade 510 to rotate, and then drive the second cylinder 200 to accelerate the rotation, so that the opening and closing performance of the valve is relatively better, and the response speed of the valve is improved.

[0048] Specifically, the rotating shaft and the second cylinder 200 can be made of hard materials such as metal or plastic, and the two can be formed in an integral manner, or the two can also form a fixed connection relationship by welding or bonding. The blade 510 is also made of hard material to ensure that the blade 510 has a structural strength that meets the requirements. Optionally, the number of blades 510 can be multiple, and the multiple blades 510 can further enhance the driving effect of the fluid acting on the connecting shaft 520 to further enhance the response speed of the valve. Further, the multiple blades 510 can be divided into multiple groups, and the multiple groups of blades 510 are distributed along the axial intervals of the cylinder body 110, and each group of blades 510 includes multiple blades 510 arranged at axial intervals around the cylinder body 110.

[0049] Therefore, when the fluid flows through the blade 510, the fluid drives the blade 510 to rotate under the action of the surface structure of the blade 510. When the blade 510 rotates, the blade 510 can drive the second cylinder 200 to rotate through the connecting shaft 520, thereby increasing the rotation speed of the second cylinder 200. In this process, the fluid still applies a force to the action part 300, and the axial distance between the action part 300 and the magnet 400 in the cylinder body 110 gradually increases, and the attraction between the two gradually decreases; and as the second cylinder 200 continues to rotate, As the second opening 210 moves, the overlapping area between the second opening 210 and the first opening gradually increases, and the flow rate of the fluid also increases accordingly, thereby increasing the driving ability of the blades 510. Under the joint action of the above-mentioned factors, the rotation speed of the second cylinder 200 can be further increased until the second cylinder 200 can no longer rotate relative to the first cylinder 100. At this time, the overlapping area between the first opening and the second opening 210 reaches the maximum, that is, the axial projection of the second opening 210 along the cylinder body 110 is located in the first opening, and the action part 300 moves to the second position.

[0050] As described above, the mounting portion 120 can be provided on only one side of the second cylinder 200. In this case, the valve is a one-way valve, which can only control the fluid on the side of the second cylinder 200 away from the mounting portion 120 to flow toward the side of the mounting portion 120 away from the second cylinder 200. In another embodiment of the present application, the number of mounting portions 120 is two, and the two mounting portions 120 are respectively provided on opposite sides of the second cylinder 200. In this case, the valve is a two-way valve, that is, the fluids on opposite sides of the valve can flow to each other when the corresponding conditions are met.

[0051] In more detail, the two mounting parts 120 are both provided with a second opening 210 and a third channel 220, and the end surfaces of the two mounting parts 120 facing the second cylinder 200 are both sealed with the end surface of the second cylinder 200, thereby preventing the fluid on both sides of the valve from forming a communication relationship from the gap between the second opening 210 and the second cylinder 200, and the first opening on the mounting part 120. At the same time, the third channel 220 extends from one end of the second cylinder 200 to the other end of the second cylinder 200, thereby ensuring that the action part 300 can move from the side where one mounting part 120 is located to the side where the other mounting part 120 is located through the combined space composed of the third channel 220 and the first channel 111. Furthermore, in order to ensure that the valve has the ability to be in a closed state, the magnet 400 is located between the two mounting portions 120 along the axial direction of the cylinder body 110, so that when the component force of the pressure difference on the opposite sides of the valve in the axial direction of the cylinder body 110 is smaller than the component force of the magnet 400 acting on the actuating portion 300 in the aforementioned axial direction, it is ensured that the magnet 400 has the ability to enable the actuating portion 300 to overcome the pressure of the fluid and move to the position where the magnet 400 is located. In this state, the first openings of each mounting portion 120 are located outside the second opening 210 of the second cylinder body 200, ensuring that the valve is in a closed state.

[0052] In the above embodiment, when the pressure difference between the two opposite sides of the valve to which the action part 300 is subjected is greater than the force component of the magnet 400 in the axial direction of the barrel body 110 in the aforementioned direction, the action part 300 can move in the second channel 122 and the third channel 220. In addition, the movement direction of the action part 300 is related to the pressure of the fluid on the opposite sides of the valve. When the pressure of the fluid on the first side of the valve is relatively large, the action part 300 moves in the direction of the second side pointing to the valve along the first side, and vice versa, when the pressure of the fluid on the second side is relatively large, the action part 300 moves in the direction of the first side pointing to the second side. Specifically, at least one of the two mounting parts 120 can be fixed to the first barrel 100 by bonding or welding, thereby ensuring that the second barrel 200 and the action part 300 can be normally installed in the inner cavity of the first barrel 100.

[0053] In the above embodiment, the second opening 210 can be specifically a columnar structure, which extends from one end of the second cylinder 200 to the other end of the second cylinder 200, so as to ensure that the opposite sides of the second cylinder 200 can be connected to each other through the second opening 210. In another embodiment of the present application, the second opening 210 includes a first perforation 211, a second perforation 212 and a receiving chamber 213, the first perforation 211 is connected to the second perforation 212 through the receiving chamber 213, and the flow rates of the first perforation 211 and the second perforation 212 are both smaller than the flow rate of the receiving chamber 213, that is, compared with the flow rates of the first perforation 211 and the second perforation 212, the flow rate of the receiving chamber 213 is relatively larger, in this case, the flow rate of the valve is only limited by the first perforation 211, the second perforation 212 and the first opening, and the flow rate will not be limited by the space size between the above three, ensuring that the valve has the function of automatic opening and closing, and the flow rate of the valve can reach the maximum. Moreover, in the present embodiment, by making the projections of the first perforation 211 and the second perforation 212 along the axial direction of the cylinder body 110 both located within the accommodating cavity 213, it is possible to ensure that the path of the fluid flowing between the first perforation 211 and the second perforation 212 is the shortest path regardless of the positions of the first perforation 211 and the second perforation 212, which can further reduce the resistance and difficulty of the fluid flowing within the second cylinder body 200 and improve the conduction performance of the valve.

[0054] Based on the above embodiment, optionally, the angle between the center of each of the two first openings and the perpendicular line of the axis of the barrel body 110 is equal to 180°, and the angle between the center of each of the first through hole 211 and the second through hole 212 and the perpendicular line of the axis of the barrel body 110 is equal to 180°. In short, the two first openings can be symmetrically arranged in the axial projection of the barrel body 110, and the second through hole 212 and the second through hole 212 can be symmetrically arranged in the axial projection of the barrel body 110.

[0055] During the operation of the valve disclosed in the above embodiment, taking one of the two first openings as an example, the first opening and the first through hole 211 rotate relative to each other and gradually approach each other, and from the critical state where the two are connected to the projection of the first through hole 211 along the aforementioned axial direction being located in the first opening, the channel between the first opening and the first through hole 211 is gradually opened, so that the direction of the fluid when flowing through the first opening and the first through hole 211 is inclined relative to the axial direction of the cylinder body 110. Furthermore, in the case of adopting the above technical solution, the initial position area of ​​the fluid flowing out of the first through hole 211 and the initial position of the fluid flowing out of the second through hole 212 are respectively located in two different half areas of the second cylinder body 200, so that when the fluid flows between the first through hole 211 and the second through hole 212, it can cover as much space between the first through hole 211 and the second through hole 212 as possible, that is, the accommodating chamber 213, thereby ensuring that the overall fluidity of the fluid in the valve is relatively high.

[0056] Furthermore, as described above, the connecting shaft 520 and the blade 510 may be provided in the valve, so as to utilize the flowing fluid to drive the blade 510 to accelerate the rotation of the second cylinder 200. Based on this, in the above embodiment, the blade 510 and the rotating shaft may be provided in the accommodating chamber 213, the axis of the rotating shaft is colinear with the axis of the second cylinder 200, and the blade 510 is connected to the rotating shaft. In this case, when the fluid flows through the first through hole 211 and the second through hole 212, the fluid may drive the rotating shaft to rotate through the blade 510, thereby driving the second cylinder 200 to rotate faster, thereby improving the response speed of the valve.

[0057] As described above, the shape and size of the action part 300 can be determined according to the cross-sectional shape and size of the combined space formed by the first channel 111 and the second channel 122. If the cross-sectional shape of the aforementioned combined space is circular, the cross-section of the action part 300 can also be circular. In this case, the action part 300 can be a cylinder. In order to reduce the difficulty of the movement of the action part 300, the end of the action part 300 can be provided with a chamfer or other structure.

[0058] In another embodiment of the present application, when the cross-sectional shape of the combined space formed by splicing the first channel 111 and the second channel 122 is circular, the action part 300 is a spherical structural part, which can further reduce the movement difficulty of the action part 300, improve the movement comfort of the action part 300, and thereby improve the comprehensive performance of the valve.

[0059] In addition, in the above embodiment, the first channel 111 and the second channel 122 can be semicircular channels, or the cross section of one of the two is a major arc and the other is a minor arc, and similarly, the first channel 111 and the third channel 220 are also the same. In order to improve the action stability of the action part 300, preferably, the shape of the cross section perpendicular to the extension direction of the first channel 111, the second channel 122 and the third channel 220 is a semicircular structure, which makes the contact area between the action part 300 and the barrel body 110 and the second barrel body 200 substantially the same, ensuring that the cooperation reliability between the two and the action part 300 is relatively high.

[0060] Optionally, the number of the action part 300 is one, and correspondingly, the number of the first channel 111, the second channel 122, and the third channel 220 are all one, and the second channel 122 and the third channel 220 are both arranged in cooperation with the first channel 111, so as to ensure that the action part 300 can reciprocate in the first channel 111 and the second channel 122, and in the first channel 111 and the third channel 220. In another embodiment of the present application, optionally, the number of the first channel 111, the second channel 122, the third channel 220, and the action part 300 are all multiple, and the multiple first channels 111 are evenly and spacedly arranged along the circumference of the barrel body 110, and the multiple action parts 300 are matched with the multiple first channels 111 in a one-to-one correspondence, and of course, the multiple second channels 122 and the multiple third channels 220 are also matched with the first channel 111 in a one-to-one correspondence. Under the action of the multiple action parts 300, the second cylinder 200 can be prevented from being deflected due to uneven force during the rotation process, so as to improve the action stability of the second cylinder 200 and further improve the reliability of the valve.

[0061] Specifically, the number of the first channel 111, the second channel 122, the third channel 220 and the action part 300 can be two, the two first channels 111 are arranged opposite to each other, and the sizes and shapes of the two first channels 111 can be made corresponding to each other. This can maximize the stability of the second cylinder 200 and the overall reliability of the valve while the processing difficulty of the valve is relatively low.

[0062] As described above, the first opening and the second opening 210 can be circular holes or rectangular holes. In the present embodiment, the first opening and the second opening 210 are both fan-shaped structures. In this case, when the action part 300 drives the second cylinder 200 to rotate, the second opening 210 and the first opening can be switched from a mutually isolated state to a mutually connected state. The initial connection area between the first opening and the second opening 210 is relatively large, and when the action part 300 moves to the second position, the connection area between the first opening and the second opening 210 is also relatively large. Moreover, in the case where the blades 510 and the connecting shaft 520 are provided on the second cylinder 200, the above technical solution can be adopted to maximize the accelerated rotation effect of the second cylinder 200, thereby maximizing the response speed of the valve. Moreover, in the above embodiment, the rotation angle and force magnitude M of the second cylinder 200 during the rotation process are as follows: Figure 7 , Fig. 9 and Fig.10 shown.

[0063] Optionally, the magnet 400 is an annular structure. In this case, no matter the action part 300 moves to any angle of the second cylinder 200, it can be ensured that the magnet 400 can provide a good magnetic driving effect for the action part 300. Specifically, the magnet 400 can be arranged on the inner side, outer side or inside the first cylinder 100, or the magnet 400 can be arranged on the outer side of the second cylinder 200 or inside the second cylinder 200. Preferably, the first cylinder 100 and the second cylinder 200 are both provided with magnets 400, and a plurality of magnets 400 are arranged around, so as to prevent the plurality of magnets 400 from generating an interaction force along the axial direction of the cylinder body 110, and further increase the magnetic driving force acting on the action part 300.

[0064] As described above, the action part 300 can drive the second cylinder 200 to reciprocate relative to the first cylinder 100. In order to reduce the difficulty of rotating the second cylinder 200, optionally, one of the mounting part 120 and the second cylinder 200 is provided with an annular guide groove 123, and the other is provided with a guide column. The limiting column 530 extends into the annular guide groove 123 along the axial direction of the cylinder body 110, so that during the relative rotation of the second cylinder 200 and the first cylinder 100, the limiting column 530 can provide guiding and limiting functions for the second cylinder 200, thereby ensuring that the rotation axis of the second cylinder 200 is always in line with the axis of the first cylinder 100, thereby improving the accuracy and reliability of the valve.

[0065] Furthermore, the annular guide groove 123 is an open annular structure, and thus, in the process of the second cylinder 200 driving the limiting column 530 to rotate, the limiting column 530 and the annular guide groove 123 that cooperate with each other can provide a limiting effect on the rotation range of the second cylinder 200, thereby ensuring that the second cylinder 200 can only rotate back and forth within a preset range, and ensuring that the valve has the ability to maintain an open state, maintain a closed state, and repeatedly switch between an open state and a closed state.
