Description

Technical Field

[0001] The utility model belongs to the technical field of building air conditioning systems, and in particular relates to a flying wing type air valve for a main pipeline of an air conditioning system. Background Art

[0002] The air valve of the air conditioning system is a device for regulating and distributing air volume. The air valves commonly used in ventilation and air conditioning systems are mostly multi-leaf regulating valves. However, when the air volume of the air outlet needs to be adjusted in the branch or near the terminal pipeline, the existing structure requires manual or electric drive of the valve plate. Its main shortcomings are:

[0003] 1. The adjustment is delayed and requires manual adjustment or complex detection, control, and execution control systems;

[0004] 2. The terminal duct system needs to be closed manually or automatically after it is deactivated. Otherwise, due to the lack of airflow, the system will cause crosstalk and leak privacy.

[0005] 3. The regulating mechanism of the air valve must be installed outside the air duct, which requires space for operation and maintenance. In particular, the electric valve also requires power distribution and control lines, which occupies the ceiling space, and the maintenance space is larger than that of the manual valve. Utility Model Content

[0006] The utility model aims to provide a flying wing type air valve, which solves the problem of heavy workload of manually adjusting the air valve in the existing air conditioning system.

[0007] The technical solution adopted by the utility model is: a flying wing type air valve, including a valve plate, the valve plate is rotatably connected to the top of the air supply pipe in the main air duct of the air-conditioning system, a flying wing is arranged above the valve plate in the direction of the airflow angle of the main air duct, the upper wing surface of the flying wing is connected to the top of the main air duct through an upper pull rope, the lower wing surface of the flying wing is connected to the valve plate through a lower pull rope, and a winder is connected to the lower side of the free end of the valve plate through a limiting pull rope.

[0008] The utility model is also characterized in that:

[0009] The flying wing is arranged in the center of the main air duct.

[0010] A plurality of upper pull ropes are arranged at intervals along the airflow direction of the main air duct.

[0011] The wire winder is fixed to the outer wall of the air supply pipe, and the end of the limit pull rope away from the wire winder passes through the side wall of the air supply pipe and is connected with the free end of the valve plate.

[0012] The connecting end of the valve plate is connected to one side of the top of the air supply pipe through a rotating shaft.

[0013] A soft magnet is fixed on the free end of the valve plate, and a contact switch is fixed on the top of the air supply pipe corresponding to the soft magnet.

[0014] The beneficial effects of the utility model are as follows: the flying wing type air valve of the utility model does not require a complicated rotating mechanism, and the air valve opening can be dynamically adjusted according to the buoyancy generated by the air volume. It can close automatically after the fan stops running to prevent crosstalk or mosquito breeding. The operation and adjustment process reduces power input or manual adjustment, and can achieve autonomous operation. BRIEF DESCRIPTION OF THE DRAWINGS

The upper wing surface of the flying wing 4 is connected to the top of the main air duct 2 through a plurality of upper pull ropes 5 arranged at intervals along the airflow direction of the main air duct 2 to fix the angle of attack of the flying wing 4. The lower wing surface of the flying wing 4 is connected to the valve plate 1 through a lower pull rope 6, and the valve plate 1 is driven to open and close through the lower pull rope 6 to control the opening and closing of the air valve and the distribution of the air volume.

The upper wing surface of the flying wing 4 is connected to the top of the main air duct 2 through three upper pull ropes 5 arranged at intervals along the air flow direction of the main air duct 2 to fix the angle of attack of the flying wing 4. The lower wing surface of the flying wing 4 is connected to the valve plate 1 through a lower pull rope 6, and the valve plate 1 is driven to open and close through the lower pull rope 6 to control the opening and closing of the air valve and the distribution of the air volume.

[0024] Example 3

[0025] The utility model provides a flying wing type air valve, including a valve plate 1, which is rotatably connected to the top of the air supply pipe 3 in the main air duct 2 of the air conditioning system through a rotating shaft 9. A flying wing 4 similar to an airplane wing is arranged above the valve plate 1 and centered in the upper and lower direction of the airflow angle of the main air duct 2, and the airflow of the main air duct 2 of the air conditioning drives the flying wing 4 to rise. The upper wing surface of the flying wing 4 is connected to the top of the main air duct 2 through three upper pull ropes 5 arranged at intervals along the airflow direction of the main air duct 2 to fix the angle of attack of the flying wing 4. The lower wing surface of the flying wing 4 is connected to the valve plate 1 through a lower pull rope 6, and the valve plate 1 is driven to open and close through the lower pull rope 6 to control the opening and closing of the air valve and the distribution of the air volume. A wire winder 8 is connected to the lower free end of the valve plate 1 through a limit rope 7. The wire winder 8 is fixed to the outer wall of the air supply pipe 3. The end of the limit rope 7 away from the wire winder 8 passes through the side wall of the air supply pipe 3 and is connected to the free end of the valve plate 1. The wire winder 8 can be fixed manually by electric self-locking function or manually retracting and releasing the wire. After the wire winder 8 is retracted, the length of the limit rope 7 can be adjusted to limit the air volume. The air outlet can also be forcibly closed during operation through the limit rope 7. On this basis, a soft magnet 10 is also fixed to the free end of the valve plate 1. A contact switch 11 is fixed to the top of the air supply pipe 3 corresponding to the soft magnet 10. The contact switch 11 is provided with a normally open contact and a normally closed contact. The contact state is controlled by the soft magnet 10, which is used to implement monitoring of the switch state of the air valve and output normally open and normally closed signals to the control system. At the same time, the valve plate 1 can be prevented from vibrating accidentally by indirectly connecting and adsorbing the soft magnet 10 to the air supply pipe 3.

[0026] Through the above method, the flying wing type air valve of the utility model does not require a complicated rotating mechanism, and the air valve opening can be dynamically adjusted according to the buoyancy generated by the air volume. It can close automatically after the fan stops running to prevent crosstalk or mosquito breeding. The operation and adjustment process reduces the power input or manual adjustment, and can achieve autonomous operation.

[0027] Example 4

[0028] The utility model provides a flying wing type air valve, including a valve plate 1, which is rotatably connected to the top of the air supply pipe 3 in the main air duct 2 of the air conditioning system through a rotating shaft 9. A flying wing 4 similar to an airplane wing is arranged above the valve plate 1 and centered in the upper and lower direction of the airflow angle of the main air duct 2, and the airflow of the main air duct 2 of the air conditioning drives the flying wing 4 to rise. The upper wing surface of the flying wing 4 is connected to the top of the main air duct 2 through three upper pull ropes 5 arranged at intervals along the airflow direction of the main air duct 2 to fix the angle of attack of the flying wing 4. The lower wing surface of the flying wing 4 is connected to the valve plate 1 through a lower pull rope 6, and the valve plate 1 is driven to open and close through the lower pull rope 6 to control the opening and closing of the air valve and the distribution of the air volume. A wire winder 8 is connected to the lower part of the free end of the valve plate 1 through a limit rope 7. The wire winder 8 is fixed to the outer wall of the air supply pipe 3. The end of the limit rope 7 away from the wire winder 8 passes through the side wall of the air supply pipe 3 and is connected to the free end of the valve plate 1. The wire winder 8 can be fixed manually after an electric self-locking function or manual wire reeling and unreeling. After the wire winder 8 is reeled in, the length of the limit rope 7 can be adjusted to limit the air volume. The air outlet can also be forcibly closed during operation through the limit rope 7. A soft magnet 10 is also fixed to the free end of the valve plate 1. A contact switch 11 is fixed to the top of the air supply pipe 3 corresponding to the soft magnet 10. The contact switch 11 is provided with a normally open contact and a normally closed contact. The contact state is controlled by the soft magnet 10, which is used to implement monitoring of the switch state of the air valve and output normally open and normally closed signals to the control system. At the same time, the indirect connection and adsorption of the soft magnet 10 to the air supply pipe 3 can prevent the valve plate 1 from vibrating accidentally. When the airflow in the main air duct 2 passes through, the wing 4 below the upper pull rope 5 is blown to generate an upward lift, which in turn drives the lower pull rope 6 to pull up the valve plate 1. The greater the air volume, the greater the lift generated, and the corresponding valve plate opening of the valve plate 1 is also larger. The soft magnetic body 10 is disconnected from the contact switch 11 to feedback to the control system that the air valve is open, which can ensure that the wind speed entering the main air duct 2 is basically stable, which is convenient for the air flow distribution of the branch pipe, i.e., the air supply pipe 3. When the air volume exceeds the air volume of the air supply pipe 3, the limit pull rope 7 controls the valve plate 1 to no longer expand the opening. When the air outlet needs to be closed or the air volume limit is adjusted, the length of the limit pull rope 7 is controlled by the winding device 8 to achieve the function of controlling the closure and limiting the air volume.

[0029] Through the above method, the flying wing type air valve of the utility model does not require a complicated rotating mechanism, and the air valve opening can be dynamically adjusted according to the buoyancy generated by the air volume. It can close automatically after the fan stops running to prevent crosstalk or mosquito breeding. The operation and adjustment process reduces the power input or manual adjustment, and can achieve autonomous operation.
