For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The dynamic balancing regulating valve 100 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0036] Reference Figure 1 , Figure 2 According to an embodiment of the present utility model, a dynamic balancing regulating valve 100 includes: a valve body 10, a balancing assembly 20 and a valve core assembly 30.

[0037] The valve body 10 is provided with an adjustment space and a first flow channel 12. The adjustment space is provided with an inlet 111 and an outlet 112. The inlet 111 is connected to the first flow channel 12. The balancing component 20 is provided in the adjustment space. The balancing component 20 separates the adjustment space into a first cavity 113 and a second cavity 114. The first cavity 113 is connected to the first flow channel 12, and the second cavity 114 is connected to the inlet 111. A limited flow channel 21 is defined between the balancing component 20 and the valve body 10. The limited flow channel 21 is connected to the inlet 111 and the outlet 112 respectively. The balancing component 20 is configured to be movable to control the size of the limited flow channel 21 according to the pressure difference between the first cavity 113 and the second cavity 114, so as to control the discharge flow of the outlet 112.

[0038] The valve core assembly 30 is rotatably disposed on the valve body 10 . The valve core assembly 30 has a blocking portion 31 . The blocking portion 31 is configured to adjustably block the inlet port 111 to control the inlet flow rate of the inlet port 111 .

[0039] Among them, the dynamic balancing regulating valve 100 automatically controls the discharge flow through the flow limiting channel 21, thereby ensuring that the discharge flow of the discharge port 112 will not change due to changes in the incoming flow pressure, thereby ensuring the stability of the downstream flow of the dynamic balancing regulating valve 100. For example, the dynamic balancing regulating valve 100 is used in a residential heating system. When a leak occurs in the first household, the flow of the second household using the dynamic balancing regulating valve 100 will not change significantly.

[0040] Among them, the flow limiting channel 21 is connected to the inlet 111 and the outlet 112 respectively. The fluid flows from the inlet 111 to the outlet 112 through the flow limiting channel 21. The size of the flow limiting channel 21 affects the discharge flow of the outlet 112. The flow limiting channel 21 is jointly defined by the balancing component 20 and the valve body 10. The balancing component 20 is movable, thereby changing the size of the flow limiting channel 21 and indirectly controlling the discharge flow.

[0041] Specifically, the first cavity 113 and the second cavity 114 are located on opposite sides of the balancing component 20, respectively. The first cavity 113 is connected to the first flow channel 12. When the pressure in the first flow channel 12 changes, the pressure in the first cavity 113 changes, and the second cavity 114 is connected to the first flow channel 12 through the inlet 111. There is a hysteresis in the change of the pressure in the second cavity 114, thereby driving the balancing component 20 to move. For example, when the pressure in the first flow channel 12 increases, the pressure in the first cavity 113 increases, and the pressure difference between the first cavity 113 and the second cavity 114 increases, which drives the balancing component 20 to move, reduces the flow-limiting flow channel 21, avoids drastic changes in the downstream flow, and ensures the stability of the downstream flow of the dynamic balancing regulating valve 100.

[0042] In the related art, a dynamic balancing control valve can be used to control the flow rate of a fluid, etc., and can achieve precise control of the flow rate of the fluid by automatically adjusting the opening of the valve. However, the error of the dynamic balancing control valve in the related art increases with the increase of usage time.

[0043] Specifically, in the related art, the dynamic balancing control valve usually uses a valve stem to adjust the initial flow of the dynamic balancing control valve. The valve stem moves in the axial direction of the inlet. A spring is provided on the valve stem. The elastic force of the spring is used to drive the valve stem to move in the axial direction. However, after long-term use, the elastic force of the spring will change, resulting in an increase in the error of the dynamic balancing control valve.

[0044] In the embodiment of the utility model, the valve core assembly 30 is rotatably mounted on the valve body 10, and the sealing portion 31 on the valve core assembly 30 can seal the inlet 111 of the sealing portion 31, and the actual working area of ​​the inlet 111 is reduced, thereby reducing the inlet flow rate, that is, the fluid flow rate entering the regulating space from the first flow channel 12 becomes smaller; the sealing portion 31 can also seal all the inlet ports 111, and the actual working area of ​​the inlet ports 111 is zero, and the inlet flow rate becomes zero, that is, the connection between the first flow channel 12 and the regulating space is cut off; the sealing portion 31 can also be rotated to not block the inlet port 111, and the actual working area of ​​the inlet port 111 is equal to the area of ​​the inlet port 111, and the inlet port 111 is fully open, and the fluid flow rate entering the regulating space from the first flow channel 12 is maximum.

[0045] Among them, the valve core assembly 30 moves in a rotational manner. Compared with the axial movement in the related art, the embodiment of the utility model does not require a spring, thereby avoiding the problem of increased errors in the later stage and improving the stability of the dynamic balancing control valve 100.

[0046] Among them, the blocking part 31 can be adjacent to the inlet port 111, and the blocking part 31 blocks one side of the inlet port 111; or, the valve body 10 is provided with a movable space connected to the inlet port 111, and the blocking part 31 is movably arranged in the movable space, and the blocking part 31 can be rotated into the inlet port 111, thereby blocking the inlet port 111.

[0047] According to the dynamic balancing control valve 100 of the embodiment of the utility model, the valve core assembly 30 is rotatably arranged on the valve body 10, and the valve core assembly 30 has a sealing portion 31, which can adjustably block the inlet port 111, thereby controlling the inlet flow of the inlet port 111. Compared with the axial movement method in the related art, the problem of increased error in the later stage is avoided, and the stability of the dynamic balancing control valve 100 is improved.

[0048] Reference Figure 2 In some embodiments, the valve core assembly 30 includes: a rotating member 32 and a blocking member 33 .

[0049] The rotating member 32 is rotatably disposed on the valve body 10 and is used to connect the driving member to drive the rotating member 32 to rotate. The blocking member 33 is disposed in the valve body 10 and is connected to the rotating member 32. The blocking member 33 has a blocking portion 31 to adjustably block the inlet 111.

[0050] A clamping member 321 is provided on the rotating member 32 . In the axial direction of the rotating member 32 , the side surface of the clamping member 321 in the axial direction abuts against the valve body 10 to limit the movement of the rotating member 32 in the axial direction.

[0051] The driving member provides power for the rotation of the rotating member 32, the driving member drives the rotating member 32 to rotate, the rotating member 32 drives the blocking member 33 to rotate, and the blocking portion 31 on the blocking member 33 can block the inlet 111 or avoid the inlet 111. The clamping member 321 is installed on the rotating member 32, and the clamping member 321 abuts against the valve body 10 to prevent the rotating member 32 from axially extending and contracting, and prevent the rotating member 32 from separating from the valve body 10.

[0052] In the above solution, by providing the clamping member 321 on the rotating member 32 and the side surface of the clamping member 321 abuts against the valve body 10 , the rotating member 32 is stabilized on the valve body 10 , so that the rotating member 32 can rotate stably.

[0053] Specifically, the driving member can be installed in the valve body 10 or on the surface of the valve body 10. The driving member can be a component of the dynamic balance regulating valve 100 itself or an external component. For example, the driving member is a driving motor, which drives the rotating member 32 to rotate.

[0054] Reference Figure 2 In some embodiments, there are multiple entrance ports 111, and the multiple entrance ports 111 are arranged at intervals. The blocking member 33 also has a blocking connection portion 331 connected to the rotating member 32. There are multiple blocking portions 31, and the multiple blocking portions 31 are respectively connected to the blocking connection portions 331, and the multiple blocking portions 31 are arranged at intervals along the circumferential direction of the blocking connection portion 331, and the blocking portions 31 are arranged corresponding to the entrance ports 111.

[0055] The plurality of inlets 111 correspond to the plurality of blocking portions 31 , and the blocking member 33 is rotated so that the plurality of blocking portions 31 block or avoid the inlets 111 .

[0056] In the above solution, by arranging a plurality of blocking portions 31 along the circumferential direction of the blocking connection portion 331 , even if the blocking member 33 is rotated at a small angle, the flow rate can be greatly changed.

[0057] Specifically, there are two inlet ports 111 and two blocking portions 31 , and the two blocking portions 31 are disposed on the blocking connection portion 331 and are spaced apart in the circumferential direction.

[0058] Reference Figure 2 In some embodiments, the blocking member 33 also has a blocking connection portion 331 connected to the rotating member 32, and the blocking portion 31 is connected to the blocking connection portion 331. In the direction away from the blocking connection portion 331, the size of the blocking portion 31 gradually increases, and the entrance 111 is set corresponding to the blocking portion 31.

[0059] Among them, the blocking part 31 is arranged on the blocking connection part 331. In the radial direction, the size of the part of the blocking part 31 away from the blocking connection part 331 is larger than the part close to the blocking connection part 331. That is, the farther away from the blocking connection part 331, the larger the width of the blocking part 31.

[0060] In the above solution, in the direction away from the blocking connection portion 331 , the size of the blocking portion 31 is gradually increased, so that the blocking portion 31 can better block the inlet 111 , thereby improving the blocking effect.

[0061] Reference Figure 3 In some embodiments, the balancing assembly 20 is sleeved on the valve core assembly 30 , and the balancing assembly 20 is movable relative to the valve core assembly 30 .

[0062] The balancing assembly 20 is sleeved on the valve core assembly 30 , the valve core assembly 30 plays a supporting role, and the balancing assembly 20 moves along the axial direction of the valve core assembly 30 .

[0063] In the above solution, by sleeve-mounting the balancing assembly 20 on the valve core assembly 30 and using the existing valve core assembly 30 to support the balancing assembly 20, the movement of the balancing assembly 20 is made more stable, thereby improving the control accuracy of the flow rate.

[0064] Reference Figure 3 In some embodiments, the valve core assembly 30 has a positioning portion 34, the positioning portion 34 is connected to an elastic member 341, and the elastic member 341 is connected to the balancing assembly 20, so that the flow limiting channel 21 has an increasing tendency.

[0065] Among them, the elastic member 341 is arranged between the positioning portion 34 and the balancing component 20. The elastic force of the elastic member 341 acts on the balancing component 20, so that the flow limiting channel 21 has a tendency to increase. The pressure difference between the first cavity 113 and the second cavity 114 needs to overcome the elastic force to push the balancing component 20 to move, so that the flow limiting channel 21 shrinks.

[0066] In the above solution, by disposing the elastic member 341 between the positioning portion 34 and the balancing assembly 20 , the balancing assembly 20 is moved by utilizing the elastic force of the elastic member 341 , so that the overall structure is simple and practical.

[0067] Specifically, the elastic member 341 may be a spring, which is sleeved on the rotating member 32 , and the elastic force of the spring acts on the balancing assembly 20 , so that the balancing assembly 20 moves obliquely upward.

[0068] Reference Figure 3 In some embodiments, the balancing assembly 20 includes: a dynamic balancing member 22 and a flexible isolation member 23 .

[0069] The dynamic balancing member 22 is movably mounted on the valve core assembly 30, and at least a portion of the inner wall of the regulating space having the inlet 111 is configured as the channel wall 115, and the dynamic balancing member 22 and the channel wall 115 jointly define the flow limiting channel 21. The flexible isolating member 23 is connected to the dynamic balancing member 22 on one side and to the inner wall of the regulating space on the other side, and the flexible isolating member 23 moves with the dynamic balancing member 22.

[0070] The dynamic balancing member 22 and the flexible isolating member 23 together separate the regulating space into a first cavity 113 and a second cavity 114. The dynamic balancing member 22 is sleeved on the valve core assembly 30. Driven by the pressure difference, the dynamic balancing member 22 moves along the axial direction of the valve core assembly 30 to expand or reduce the flow limiting passage 21. The flexible isolating member 23 is flexible. Driven by the dynamic balancing member 22, one end of the flexible isolating member 23 moves along the axial direction of the valve core assembly 30, while the other end of the flexible isolating member 23 is always fixed to the inner wall of the regulating space to isolate the first cavity 113 from the second cavity 114.

[0071] It should be noted that the space between the dynamic balancing member 22 and the channel wall 115 is the flow limiting channel 21. When the dynamic balancing member 22 is close to the channel wall 115, the flow limiting channel 21 is reduced, and when the dynamic balancing member 22 is away from the channel wall 115, the flow limiting channel 21 is expanded.

[0072] In the above scheme, by cooperating with the dynamic balancing member 22 and the flexible isolating member 23, the first cavity 113 and the second cavity 114 are better isolated by utilizing the flexible property of the flexible isolating member 23, the sealing is better, and the balancing assembly 20 moves more smoothly, thereby improving reliability.

[0073] Specifically, the flexible isolation member 23 is a diaphragm structure, and the flexible property of the diaphragm structure is utilized to achieve a better effect.

[0074] Reference Figure 8 In some specific embodiments, the valve body 10 includes a sub-component 17, and the inlet 111 is provided on the sub-component 17. By splitting the valve body 10 into the sub-components 17, the structure is simplified and the molding of each part is facilitated.

[0075] Reference Figure 4 In some embodiments, the dynamic balancing member 22 includes a balancing body portion 221 , a balancing connection portion 222 and a balancing extension portion 223 .

[0076] The balancing body 221 is provided with a mounting hole 2211, and the valve core assembly 30 is inserted into the mounting hole 2211, and the valve core assembly 30 is sealed and matched with the balancing body 221. The balancing connection portion 222 is provided on the balancing body 221, and extends in a direction away from the balancing body 221. The balancing extension portion 223 is connected to one end of the balancing connection portion 222 away from the balancing body 221, and the balancing extension portion 223 at least partially extends along the axial direction of the valve core assembly 30, and the side of the balancing extension portion 223 facing the channel wall 115 and the channel wall 115 together define the flow limiting channel 21.

[0077] The balancing body 221 is sleeved on the valve core assembly 30, and the balancing body 221 moves along the axial direction of the valve core assembly 30. The balancing body 221 and the valve core assembly 30 are sealed to ensure the sealing of the second cavity 114. The balancing connection part 222 is arranged between the balancing body 221 and the balancing extension part 223. The balancing connection part 222 plays a connecting role. The balancing extension part 223 extends in the direction of the channel wall 115. The side of the balancing extension part 223 facing the channel wall 115 and the channel wall 115 together define the flow limiting channel 21.

[0078] In the above solution, through the cooperation of the balancing body 221, the balancing connection part 222 and the balancing extension part 223, the size of the flow limiting channel 21 is controllable, and the dynamic balancing member 22 works stably by structural cooperation, thereby improving reliability.

[0079] Specifically, the dynamic balancing member 22 is integrally constructed as a rotating member, and the rotating member is sleeved on the rotating member 32, thereby improving the stability of the rotating member.

[0081] Among them, the connecting channel 13 connects the first cavity 113 and the first channel 12. In the flow direction of the liquid in the first channel 12, the connecting channel 13 is located upstream of the inlet 111. Part of the liquid in the first channel 12 first flows into the connecting channel 13, and the other part flows downstream, and the other part enters the second cavity 114 through the inlet 111.

[0082] In the above scheme, a connecting channel 13 is provided on the valve body 10 to connect the first cavity 113 and the first channel 12, and the portion where the connecting channel 13 is connected to the first channel 12 is located upstream of the inlet 111. Compared with the connecting channel provided on the valve core in the related art, the reliability is improved and the overall stability is stronger.

[0084] The first flow channel 12 is disposed on the base 14 . The cover 15 is disposed on the base 14 , and the base 14 and the cover 15 together define an adjustment space. The inlet 111 and the outlet 112 are both disposed on the base 14 .
