Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an automatic variable air volume ventilation regulating valve. Background Technology

[0002] A ventilation regulating valve is a valve body used to regulate airflow. It is usually installed on the supply and return air ducts of ventilation or air conditioning systems with high air quality requirements.

[0003] The ventilation regulating valve consists of a housing and blades. Multiple blades are mounted on the housing and connected by a linkage mechanism to achieve synchronous rotation of the blades. The valve body opens and closes in real time by the rotation of the blades, and the air supply volume of the valve body can be adjusted by adjusting the opening angle of the blades.

[0004] The inventors of this application have discovered that in current ventilation regulating valves, the blades are connected to a handle via a rotating shaft, and the handle drives the blades to rotate. During use, the regulating valve can only deliver a fixed amount of air and cannot adjust the airflow based on environmental data, which affects comfort and increases the energy consumption of the air conditioning system. Utility Model Content

[0005] The purpose of this invention is to provide an automatic variable air volume ventilation regulating valve to solve the problems mentioned in the background art.

[0006] This utility model provides an automatic variable air volume ventilation regulating valve, including: a housing, blades, an electric actuator, a sensor, and a controller;

[0007] The shell is square-frame shaped;

[0008] The blades are provided in multiple ways, and each blade is rotatably mounted on the housing via a rotating shaft and connected by a linkage mechanism to make the multiple blades rotate synchronously.

[0009] The electric actuator is mounted on the housing and is connected to the rotating shaft. The electric actuator is used to drive the blades to rotate in order to control the opening and closing of the regulating valve. When the regulating valve is closed, the edges of two adjacent blades abut against each other.

[0010] The sensor and the controller are respectively mounted on the housing, with the sensor located on the side closer to the air inlet;

[0011] The sensor and the electric actuator are electrically connected to the controller. The sensor is used to detect environmental data and send the detected environmental data to the controller. The controller is used to send control signals to the electric actuator according to the environmental data to adjust the air supply volume.

[0012] Based on the above scheme, the automatic variable air volume ventilation regulating valve of this utility model comprises a housing, blades, an electric actuator, a sensor, and a controller. Multiple blades are rotatably mounted on the housing via rotating shafts and connected by a linkage mechanism. The electric actuator is mounted on the housing and connected to the rotating shaft.

During operation, the sensor continuously monitors the indoor environmental data and sends it to the controller. The controller calculates the required airflow based on preset parameters and the received environmental data, and sends corresponding control signals to the electric actuator. The electric actuator controls the opening amplitude of the blades, thereby controlling the airflow. This achieves automatic adjustment and precise control of airflow according to actual needs, avoiding the excessive or insufficient airflow often seen in traditional constant airflow systems. This reduces system energy consumption, achieves energy saving and consumption reduction, and reduces resource waste. It is widely used in commercial buildings, industrial plants, laboratories, and other places with high ventilation requirements.

[0035] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0036] As described in the background section of this application, the ventilation regulating valve consists of a housing and blades. Multiple blades are mounted on the housing and connected by a linkage mechanism to achieve synchronous rotation of the blades. The valve body opens and closes in real time by the rotation of the blades, and the air volume of the valve body can be adjusted by adjusting the opening angle of the blades.

[0037] The inventors of this application have discovered that in current ventilation regulating valves, the blades are connected to a handle via a rotating shaft, and the handle drives the blades to rotate. During use, the regulating valve can only deliver a fixed amount of air and cannot adjust the airflow based on environmental data, which affects comfort and increases the energy consumption of the air conditioning system.

[0038] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

[0039] Figure 1 This is a rear view schematic diagram of the automatic variable air volume ventilation regulating valve in an embodiment of this utility model. Figure 2 This is a side view of the ventilation regulating valve in an embodiment of the present invention. Figure 3 This is a three-dimensional schematic diagram of the ventilation regulating valve in an embodiment of this utility model.

[0040] like Figures 1 to 3 As shown, the automatic variable air volume ventilation regulating valve of this embodiment includes: housing 1, blade 2, electric actuator 3, sensor 4 and controller 5.

[0041] The shell 1 has a rectangular frame structure and a rectangular cross-section.

[0042] The blades 2 are thin plates, and multiple blades are provided. Each blade 2 is rotatably mounted on the housing 1 via a pivot 21 at both ends, located within the frame of the housing 1, and positioned at the midpoint of the housing 1 in the front-rear direction. The pivot 21 of one blade 2 extends beyond the side wall of the housing 1. The multiple blades 2 are connected by a linkage mechanism (not shown in the figure), which enables the multiple blades 2 to rotate synchronously.

[0043] When the regulating valve is closed, the adjacent edges of two adjacent blades 2 overlap and press against each other to reduce the gap between adjacent blades 2 and reduce the air leakage rate of the valve body.

[0044] The electric actuator 3 is installed on the outer wall of the housing 1 and is connected to the rotating shaft 21 extending out of the housing 1. The electric actuator 3 is used to drive the blade 2 to rotate in order to control the opening and closing of the regulating valve (blade). The electric actuator 3 can also adjust the rotation opening of the blade 2 to adjust the air volume of the valve body.

[0045] Sensor 4 is mounted on housing 1, located on the side of housing 1 near the air inlet. Sensor 4 is used to detect environmental data of the indoor space in real time.

[0046] The controller 5 is mounted on the outer wall of the housing 1, and the electric actuator 3 and the sensor 4 are electrically connected to the controller 5 respectively.

[0047] In this embodiment, when the ventilation regulating valve is in use, the sensor detects the environmental data of the indoor space in real time and sends the detected environmental data to the controller. The controller calculates the required air volume based on preset parameters and the received actual environmental data, and sends the corresponding control signal to the electric actuator. The electric actuator controls the opening amplitude of multiple blades, thereby controlling and adjusting the air volume in real time, realizing precise adjustment and control of the air volume to meet the strict requirements of the indoor space for air flow and improve energy utilization.

[0048] As can be seen from the above, the automatic variable air volume ventilation regulating valve of this embodiment comprises a housing, blades, an electric actuator, a sensor, and a controller. Multiple blades are rotatably mounted on the housing via shafts and connected by a linkage mechanism. The electric actuator is mounted on the housing and connected to the shaft. The sensor and controller are also mounted on the housing and electrically connected to the controller. In this embodiment, the automatic variable air volume ventilation regulating valve allows the sensor to monitor indoor environmental data in real time and send this data to the controller. The controller calculates the required airflow based on preset parameters and the received environmental data, and sends a corresponding control signal to the electric actuator. The electric actuator controls the opening amplitude of the blades, thereby controlling the airflow. This achieves automatic adjustment and precise control of airflow according to actual needs, avoiding the excessive or insufficient airflow often seen in traditional constant air volume systems. This reduces system energy consumption, achieves energy saving and consumption reduction, and minimizes resource waste.

[0049] Optionally, in this embodiment, the automatic variable air volume ventilation regulating valve has blade baffles 11 on the inner walls of the upper and lower sides of the housing 1.

[0050] When the regulating valve (blade) is closed, the edge of the outermost blade 2 overlaps and fits against the blade baffle 11 of the housing 1 to reduce the gap between the blade 2 and the housing 1, making the regulating valve more airtight and further reducing the air leakage rate when the valve body is closed; and the blade baffle 11 also restricts the rotation of the blade 2 when it abuts against the blade 2.

[0051] Optionally, in this embodiment, the automatic variable air volume ventilation regulating valve has a housing 1 with a reinforcing rib plate 12. The two ends of the reinforcing rib plate 12 are respectively fixed on the inner walls of the two sides of the housing 1 to enhance the strength and rigidity of the housing 1. The reinforcing rib plate 12 is located on the side of the housing 1 near the air inlet, and the reinforcing rib plate 12 is not visible from the air outlet side of the housing 1, making the valve body more aesthetically pleasing.

[0052] Furthermore, in this embodiment, the sensor 4 of the automatic variable air volume ventilation regulating valve is mounted on the reinforcing rib plate 12 of the housing 1, which facilitates the installation and fixation of the sensor 4.

[0053] Optionally, in this embodiment, the automatic variable air volume ventilation regulating valve has a housing 1 with fixed protrusions 13 on both sides of the air inlet and air outlet, and the fixed protrusions 13 are provided with fixed through holes 14.

[0054] In this embodiment, the fixed protrusion 13 forms a flange structure on the housing 1, which facilitates the installation and fixing of the valve body.

[0055] Optionally, in this embodiment, the automatic variable air volume ventilation regulating valve has a housing 1 and blades 2 made of galvanized steel sheet.

[0056] Optionally, in this embodiment, the environmental data detected by the sensor 4 of the automatic variable air volume ventilation regulating valve includes: temperature data, humidity data, and the flow rate and pressure of the supply airflow.

[0057] Optionally, in this embodiment, the automatic variable air volume ventilation regulating valve controller 5 is electrically connected to the remote control center of the indoor building.

[0058] Controller 5 is integrated with the building's remote control center, enabling remote control and automated management of Controller 5. Through the remote control center, operators can easily monitor and adjust the regulating valves in various areas in real time, improving management efficiency and reducing labor costs.

Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
