DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0035] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0036] Embodiment: A smart flow control valve for a heating system, see attached Figure 1 -Attached Figure 6 , including a valve tube 1, a connecting tube 2, a connecting hole 11, a valve core 3 and an adjusting mechanism 4, wherein the valve tube 1 is configured as a round tube and is vertically arranged, and the top and bottom of the valve tube 1 are sealed; two connecting tubes 2 are provided and are respectively connected to the two sides of the valve tube 1; two connecting holes 11 are provided on the hole wall of the valve tube 1, and the connecting holes 11 are configured as square holes, and the heights of the two connecting holes 11 are different, and the two connecting tubes 2 are connected to the valve tube 1 through the two connecting holes 11 respectively; the valve core 3 is configured as a round plate, the valve core 3 is coaxial with the valve tube 1 and fits with the inner wall of the valve tube 1, and the valve core 3 changes the flow area of ​​one of the connecting holes 11 by moving up and down; the adjusting mechanism 4 is used to drive the valve core 3 to move up and down in the valve tube 1.

[0037] In this embodiment, by setting the valve core 3 and the square connection hole 11, the flow area of ​​one of the connection holes 11 can be controlled by moving the valve core 3 up and down. Take the upper connection hole 11 of the two connection holes 11 as an example for explanation. When the valve core 3 moves to the upper connection hole 11, the part of the upper connection hole 11 located at the top of the valve core 3 cannot flow water to the lower connection hole 11. Only the part of the upper connection hole 11 located below the valve core 3 can flow water to the lower connection hole 11. The area of ​​the part of the upper connection hole 11 located below the valve core 3 is the flow area of ​​the connection hole 11. The size of the flow area can be controlled by moving the valve core 3 up and down. The connection hole 11 is set as a square hole, and the two opposite side lines of the square hole are horizontal, and the other two opposite side lines are vertical, so that the distance of the valve core 3 moving up and down is linearly related to the flow area of ​​the connection hole 11, so that the flow control by the valve core 3 is simpler and the control accuracy is higher.

[0038] Specifically, the valve core 3 includes a core plate 31 and a sealing ring 32 . The core plate 31 is configured as a circular plate and is coaxial with the valve tube 1 . The sealing ring 32 is sleeved outside the core plate 31 and the outer side of the sealing ring 32 is in contact with the inner wall of the valve tube 1 .

[0039] The core plate 31 is provided with a plurality of clearance holes 33 which vertically penetrate the core plate 31 and are arranged around the axis of the core plate 31 , and an elastic membrane 34 is provided in the clearance holes 33 to block the clearance holes 33 .

[0040] Taking the valve core 3 controlling the upper connecting hole 11 as an example, when the valve core 3 moves to the top of the upper connecting hole 11 and continues to move upward, the water on the top of the valve core 3 cannot be isolated at the top of the valve core 3. The upward movement of the valve core 3 will squeeze the water and increase the resistance of the valve core 3 to the upward movement. Through the setting of the elastic membrane 34, the elastic deformation of the elastic membrane 34 can reduce the squeezing of the water and reduce the resistance encountered by the valve core 3 when it continues to move upward.

[0041] The adjusting mechanism 4 includes a rotating rod 41, a guide rod 42 and a motor 43. The rotating rod 41 is rotatably connected to the valve tube 1 and is coaxial with the valve tube 1. The rotating rod 41 penetrates the core plate 31 in the vertical direction and is threadedly connected to the core plate 31. The guide rod 42 is fixedly connected to the valve tube 1 and is vertically arranged. The guide rod 42 vertically penetrates the core plate 31 and the core plate 31 can slide vertically on the guide rod 42. The motor 43 is used to drive the rotating rod 41 to rotate.

[0042] By setting the guide rod 42, when the motor 43 drives the rotating rod 41 to rotate, the core plate 31 will not rotate along with the rotating rod 41, so that the rotating rod 41 can drive the core plate 31 to move up and down by rotating.

[0043] Specifically, the top and bottom of the valve tube 1 are respectively a top plate and a bottom plate, a rotating rod 41 vertically penetrates the top plate, and a sealing assembly 6 is arranged between the rotating rod 41 and the top plate; a power box 5 is fixedly connected to the top of the valve tube 1, a driven gear 44 located in the power box 5 is fixedly connected to the rotating rod 41, the motor 43 is fixedly connected to the top of the power box 5, the output shaft of the motor 43 extends downward into the power box 5, and a driving gear 45 meshing with the driven gear 44 is fixedly connected to the output shaft of the motor 43, and the number of teeth of the driving gear 45 is less than the number of teeth of the driven gear 44.

[0044] By setting the driving gear 45 and the driven gear 44, the rotation speed of the rotating rod 41 can be reduced at a higher rotation speed output by the motor 43, so as to facilitate the control of the number of rotations of the rotating rod 41 and thus control the distance of the core plate 31 moving up and down.

[0045] Specifically, a support frame 51 is fixedly connected inside the power box 5, the rotating rod 41 is rotatably connected to the support frame 51 through a bearing, and one end of the top of the rotating rod 41 is rotatably connected to the top of the power box 5 through a bearing.

[0046] Specifically, a mounting hole 12 for the power pipe to pass through is opened on the top plate.

[0047] The sealing assembly 6 includes a first sealing ring 61 and a second sealing ring 62. The first sealing ring 61 is fixedly connected to the inner wall of the mounting hole 12 and the inner wall of the first sealing ring 61 is in contact with the outer wall of the rotating rod 41. The second sealing ring 62 is fixedly connected to the outside of the rotating rod 41 and the outer wall of the second sealing ring 62 is in contact with the inner wall of the mounting hole 12. The first sealing ring 61 and the second sealing ring 62 are arranged alternately in the vertical direction, and the adjacent first sealing rings 61 and the second sealing ring 62 are in contact with each other. The sealing assembly 6 includes two second sealing rings 62 and three first sealing rings 61. The top and bottom of the two second sealing rings 62 are in contact with the first sealing ring 61. The top and bottom of the second sealing ring 62 are provided with an annular sealing groove 63. The two sealing grooves 63 at the top and bottom of the second sealing ring 62 are provided with two third sealing rings 64 that match the sealing groove 63 and are respectively fixedly connected to the two first sealing rings 61 at the top and bottom of the first sealing ring 61.

[0048] By providing the first sealing ring 61, the second sealing ring 62, the sealing groove 63 and the third sealing ring 64, the sealing performance of the connection between the rotating rod 41 and the top plate can be improved, so that water is not easily leaked from the connection between the rotating rod 41 and the top plate.

[0049] Specifically, the axes of the two connecting pipes 2 are horizontal and coaxial, and the connecting pipes 2 are connected to the valve pipe 1 through a bend pipe; the ends of the two connecting pipes 2 away from the valve pipe 1 are fixedly connected with a flange 21; the two connecting pipes 2 are set to be coaxial and flanges 21 are set on the two connecting pipes 2 to facilitate the installation of the regulating valve.

[0050] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
