[0054] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0055] Refer to Figures 1-5 , a multifunctional pipeline check valve, comprising: a valve pipe 13, a buffer pipe 12, a bracket 17, a rotating shaft 18, a linkage plate 19, a connecting plate 21, a cover plate 22, a sleeve 24, an installation pipe 11, and a torsion spring 20.

[0056] The installation pipe 11 is fixedly connected to one end of the buffer pipe 12. An internal thread is provided on the inner wall of the end of the installation pipe 11 away from the buffer pipe 12. The buffer pipe 12 is a corrugated pipe, which is elastic. One end of the buffer pipe 12 is fixedly connected to the end wall of the valve pipe 13, and the other end of the buffer pipe 12 is fixedly connected to the end wall of the installation pipe 11. The installation pipe 11, the buffer pipe 12, and the valve pipe 13 are in the same communication. A platform groove 14 is provided on the side wall of the valve pipe 13. There are two brackets 17 which are symmetrically positioned and fixedly connected to the platform groove 14. There are two rotating shafts 18 which are respectively rotatably connected to the two brackets 17. The linkage plate 19 is fixedly connected between the two rotating shafts 18. The cover plate 22 is fixedly connected to one end of the connecting plate 21. The cover plate 22 fits on one side end wall of the valve pipe 13 and closes one side channel of the valve pipe 13. There are two sleeves 24 which are symmetrically positioned and fixedly connected to the top wall of the platform groove 14. The torsion spring 20 is sleeved on the rotating shaft 18. One end of the torsion spring 20 is fixedly connected to the side wall of the bracket 17, and the other end of the torsion spring 20 is fixedly connected to the side wall of the linkage plate 19.

[0057] In order to control the cover plate 22 to close the channel in the valve pipe 13, two groups of magnetic components are also provided. The magnetic components include: a return spring 29, a first magnet 28, a second magnet 26, a universal ball 25, and a third magnet 16.

[0058] There is a chute 27 in the sleeve 24. The first magnet 28 is slidably connected in the chute 27. The second magnet 26 is slidably connected in the chute 27. The second magnet 26 and the first magnet 28 are respectively slidably connected in the chute 27, and the annular side walls of the second magnet 26 and the second magnet 26 respectively slide in contact with the inner wall of the chute 27. One end of the return spring 29 is fixedly connected to the groove wall of the chute 27, and the other end of the chute 27 is fixedly connected or abutted against the end wall of the first magnet 28. The universal ball 25 is fixedly connected to one end of the second magnet 26. The universal ball 25 is installed on the bottom wall of the linkage plate 19. The second magnet 26 and the first magnet 28 are like-pole magnets. The third magnet 16 is fixedly connected inside the end wall of the valve pipe 13. The cover plate 22 is made of iron material and the third magnet 16 has a suction force on the cover plate 22. A groove 15 is provided on one end wall of the valve pipe 13. A sealing ring 23 is fixedly connected to the side wall of the cover plate 22. The side wall of the sealing ring 23 is in sealing contact with the groove wall of the groove 15.

[0059] Working or installation process:

[0060] Initial state: The cover plate 22 completely fits on one end of the valve pipe 13 and at this time the sealing ring 23 is in sealing contact with the groove wall of the groove 15. The third magnet 16 attracts the side wall of the cover plate 22; the torsion spring 20 is in a non-twisted state, the return spring 29 is in a non-loaded state, and the second magnet 26 and the first magnet 28 repel each other;

[0061] Threadedly install the installation pipe 11 on the pipeline, and make the water flow direction from the installation pipe 11 to the valve pipe 13. When the water flow is large and directly impacts the cover plate 22 that fits against the valve pipe 13 instantaneously, the cover plate 22 receives a large impact force. Since the buffer pipe 12 is a corrugated pipe and has the functions of deforming and being elastic, the impact force of the water flow can stretch the buffer pipe 12 by a certain amount, thereby realizing the function of reducing the impact force on the cover plate 22;

[0062] The water flow impacts the side wall of the cover plate 22, and the impact force of the water flow is greater than the suction force between the third magnet 16 and the cover plate 22. At this time, the cover plate 22 makes a positive circular rotation around the rotating shaft 18 through the connecting plate 21 and the linkage plate 19. While the cover plate 22 drives the connecting plate 21 and the linkage plate 19 to rotate around the rotating shaft 18, the torsion spring 20 is twisted, and the torsion spring 20 generates a torsion force;

[0063] Since the linkage plate 19 makes a circular rotation around the rotating shaft 18 and the linkage plate 19 is ball-jointed with the universal ball 25, the universal ball 25 is squeezed during the rotation of the linkage plate 19. The universal ball 25 squeezes the second magnet 26 downward. Due to the limiting and guiding effect of the side wall of the chute 27 on the second magnet 26, the second magnet 26 can only move vertically along the extending direction of the inner wall of the chute 27. Since there is a magnetic force of like repulsion between the second magnet 26 and the first magnet 28, the second magnet 26 pushes the first magnet 28 downward through the magnetic force of like repulsion. The first magnet 28 squeezes the return spring 29, making the return spring 29 compressed and having elastic potential energy; And during this process, the water flow in the valve pipe 13 always maintains the same flow rate and impact force to impact the cover plate 22. By the water flow impacting the cover plate 22, the cover plate 22 rotates and opens, and the water flow flows out from one end of the valve pipe 13; Since the universal ball 25 is ball-jointed with the linkage plate 19 and the chute 27 has a limiting and guiding effect on the second magnet 26, the rotation angle of the cover plate 22 around the rotating shaft 18 has a maximum limit, thereby controlling the maximum flow rate flowing out of the valve pipe 13; Realize the function of controlling the maximum water output;

[0064] When there is no water flowing in the installation pipe 11, the cover plate 22 no longer receives the impact force of the water flow. The torsion spring 20 releases its own torsional elastic potential energy, and the return spring 29 releases its own elastic potential energy and pushes the first magnet 28 upward. The first magnet 28 pushes the second magnet 26 upward through the repulsive force of like repulsion between the first magnet 28 and the second magnet 26, thereby making the linkage plate 19 make a reverse circular rotation around the rotating shaft 18. When the cover plate 22 rotates to the side close to the third magnet 16, the attractive force of the third magnet 16 on the cover plate 22 gradually increases, thereby realizing the process that the cover plate 22 drives the sealing ring 23 to rotate quickly and fit against the end wall of the valve pipe 13. And at this time, the side wall of the sealing ring 23 is in sealing contact with the groove wall of the groove 15. Thereby closing the channel of the valve pipe 13 and preventing the water from flowing back.
