[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a technical solution:

[0022] An energy efficiency gradient regulating control valve assembly for a building heating, ventilation and air conditioning system includes a control valve 1, a control plate 2 disposed on the inner wall of the control valve 1, the outer side of the control plate 2 being connected to the inner wall of the control valve 1, a rubber pad 3 disposed on the inner side of the control plate 2, the outer side of the rubber pad 3 being connected to the inner side of the control plate 2, and a flow plate 7 disposed inside the control valve 1.

[0023] A temperature sensor 4 is provided on one side of the control board 2, and one side of the temperature sensor 4 is connected to one side of the control board 2. A motor 5 is provided on one side of the control board 2, and one end of the motor 5 is connected to one side of the control board 2.

[0024] A rotating rod 6 is provided at the output end of motor 5. One end of the rotating rod 6 is connected to the output end of motor 5, and a flow plate 7 is provided at the other end of the rotating rod 6. One side of the flow plate 7 is connected to one end of the rotating rod 6.

[0025] There are two control plates 2, which are symmetrically distributed on the inner wall of the control valve 1. One side of the control plate 2 has an inlet hole. The flow plate 7 is cross-shaped and has a flow passage hole on one side. The diameter of the flow passage hole gradually decreases, so that the flow rate can be controlled quickly and conveniently, and thus more accurately.

[0026] A filter screen 8 is provided on the inner wall of the control valve 1. The outer side of the filter screen 8 is in contact with the inner wall of the control valve 1. A limit plate 9 is provided on one side of the filter screen 8. One side of the limit plate 9 is connected to one side of the filter screen 8. A fixing bolt 10 is provided on the inner wall of the limit plate 9. The outer wall of the fixing bolt 10 is threadedly connected to the inner wall of the limit plate 9.

[0027] There are two filter screens 8, which are symmetrically distributed on the inner wall of the control valve 1. There are six limit plates 9, which are symmetrically distributed on one side of the filter screens 8. Limit holes are opened in the inner wall of the control valve 1. One end of the fixing bolt 10 is threaded to the inner wall of the limit hole, so that impurities in the water can be filtered quickly and conveniently, and the filter screens 8 can be quickly and conveniently installed and removed, thus enabling better use.

[0028] When needed, the operator fixes control valve 1 in the building's HVAC system. Temperature sensor 4, installed on one side of control panel 2, monitors the temperature inside control valve 1 and controls motor 5. Motor 5 drives rotating rod 6, which in turn rotates flow plate 7. The flow plates 7 have varying diameter orifices, decreasing in size sequentially. Temperature sensor 4 controls the rotation of these orifices based on the monitored temperature. First, the larger diameter orifice aligns with the inlet orifice on control panel 2, increasing flow velocity. When the temperature approaches the set value, the smaller diameter orifice aligns with the inlet orifice on control panel 2. The rubber dot 3 is fitted to reduce flow and maintain a stable indoor temperature. In low-temperature winter environments, the rubber dot 3 shrinks due to the temperature drop, causing deformation to compensate for the size changes of the control plate 2 and ensure normal valve regulation. By installing the filter screen 8, impurities such as rust in the heating water can be filtered out, thus improving its performance. When the filter screen 8 needs to be removed, the fixing bolt 10 is rotated to move it on the inner wall of the limit plate 9. The movement of the fixing bolt 10 allows it to be pulled out from the inner wall of the control valve 1, thereby canceling the limit fixation of the filter screen 8. At this time, the filter screen 8 can be removed. When it needs to be installed, the above steps are repeated in reverse, making it more convenient for operators to use.
