Description

Technical Field

[0001] The present application relates to the technical field of fan valves, and in particular to a control structure for a fan valve. Background Art

[0002] A fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. During the use of the fan, in order to facilitate the adjustment of its air volume, an adjustable valve is used to change the air volume of the fan. The air volume regulating valve is an indispensable end accessory for central air conditioners in industrial factories, hot air discharge of metallurgical heating furnaces, ventilation of civil buildings, air conditioning, and air purification projects. It is generally used in air conditioning and ventilation system pipelines to regulate the air volume of branch pipes and can also be used for the mixed regulation of fresh air and return air.

[0003] The existing fan valves are flush with each other. After the fan valve rotates and opens, the direction of the airflow changes after hitting the valve, but this way of opening the valve will cause the airflow to be not smooth enough, and further increase the energy consumption of the fan. Summary of the Utility Model

[0004] In order to improve the problem that the existing way of opening the fan valve causes the airflow to be not smooth enough, the present application provides a control structure for a fan valve.

[0005] The present application provides a control structure for a fan valve, including a fan and a valve installed at the output port of the fan. The valve includes a mounting frame fixedly connected to the fan. Four flow deflectors are rotatably connected to the inner walls on both sides of the mounting frame. A rectangular groove is formed in the outer wall of one side of the mounting frame, and a linkage component for driving the flow deflectors to rotate is arranged on the inner wall of the rectangular groove. The linkage component includes a first rotating ear, a second rotating ear, a third rotating ear, and a fourth rotating ear respectively rotatably connected to the inner wall of the rectangular groove. The first rotating ear, the second rotating ear, the third rotating ear, and the fourth rotating ear are sequentially fixedly connected to the transmission shafts of the four flow deflectors, and a driving component is installed on the inner wall of the rectangular groove.

[0006] With the above structure, by setting a valve on the fan, the opening and closing of the valve are convenient for controlling the on-off of the output port of the fan. The rotation of the flow deflectors in the mounting frame is convenient for controlling the on-off of the delivery port of the fan. The linkage component is arranged in the rectangular groove of the mounting frame, and the linkage component is convenient for directly controlling the rotation of the flow deflectors. The setting of the driving component is convenient for driving the rotating ears to drive the flow deflectors to rotate.

[0007] The same connecting rod one is rotatably connected between the first rotating ear and the third rotating ear, and one end of the transmission shaft of the fourth rotating ear is fixedly connected to a fifth rotating ear.

[0008] With the above structure, the setting of the connecting rod one facilitates the synchronous rotation of the first rotating ear and the third rotating ear, and the synchronous rotation of the fourth rotating ear and the fifth rotating ear.

[0009] A connecting rod two is rotatably connected between the rotating ear five, the rotating ear three and the rotating ear two, and a telescopic rod is rotatably connected between the rotating ear two and the rotating ear three. Both the rotating ear three and the rotating ear two are V-shaped structures.

[0010] With the above structure, the setting of the connecting rod two facilitates the synchronous rotation of the rotating ear five, the rotating ear three and the rotating ear two.

[0011] The driving assembly includes a driving box fixedly connected to the inner wall of the rectangular groove, and a driving column is slidably connected to the inner wall of the driving box.

[0012] With the above structure, the setting of the driving box facilitates the sliding installation of the driving column.

[0013] A driving rod is rotatably connected between the driving column and the rotating ear four, and the cross section of the driving column is a T-shaped mechanism.

[0014] With the above structure, the setting of the driving rod facilitates directly driving the rotation of the rotating ear four, and the setting of the driving column facilitates driving the movement of the driving rod.

[0015] A mounting frame is fixedly connected to the inner wall of the driving box, and a screw rod is rotatably connected to the outer wall of one side of the mounting frame.

[0016] With the above structure, the setting of the mounting frame facilitates the installation of the screw rod.

[0017] A threaded groove is formed in the outer wall of one side of the driving column, and the screw rod is screwed on the inner wall of the threaded groove.

[0018] With the above structure, the rotation of the screw rod directly drives the movement of the driving column.

[0019] A servo motor is fixedly connected to the inner wall of the driving box, and the output shaft of the servo motor is fixedly connected to the screw rod.

[0020] With the above structure, the setting of the servo motor facilitates directly driving the rotation of the screw rod, thereby facilitating driving the movement of the driving column, and further facilitating the adjustment of the rotation of the flow deflector.

[0021] In summary, the beneficial effects of the present application are as follows:

[0022] 1. In the present application, a valve is provided at the output port of the fan. The setting of multiple rotatable flow deflectors in the valve facilitates directly controlling the on-off of the valve. A linkage assembly is also provided on the mounting frame. The setting of the linkage assembly facilitates directly driving the opening and closing of the flow deflectors. The setting of the linkage assembly facilitates actively controlling the actions of the flow deflectors, thereby ensuring that the air flow can pass smoothly when the valve is opened.

[0023] 2. This application solves the problem that the passive opening of the existing fan valve affects the smoothness of the air flow by setting a driving component in the linkage component. In the driving component, the servo motor drives the screw to rotate. When the screw rotates, it directly drives the driving column to move. When the driving column moves, it drives the rotating ear to rotate through the driving rod, thereby facilitating the direct driving of multiple flow deflectors to rotate.

A driving component 6 is installed on the inner wall of the rectangular groove.

[0032] During use, by setting a valve 2 on the fan 1, the opening and closing of the valve 2 facilitate the control of the on-off of the output port of the fan 1.

The setting of the driving assembly 6 facilitates driving the rotating ear to drive the flow deflector 4 to rotate.

[0033] Refer to Figures 3-4 , a same connecting rod 1 is rotatably connected between the rotating ear 1 and the rotating ear 3. One end of the transmission shaft of the rotating ear 4 is fixedly connected to a rotating ear 5. Through the setting of the connecting rod 1, it is convenient to make the rotating ear 1 and the rotating ear 3 rotate synchronously, and the rotating ear 4 and the rotating ear 5 rotate synchronously.

[0034] Refer to Figure 3 and Figure 4 , a same connecting rod 2 is rotatably connected between the rotating ear 5, the rotating ear 3 and the rotating ear 2.
