Description

Technical Field

[0001] The present invention relates to the technical field of air valves, and in particular to a sealed air valve structure. Background Art

[0002] The air valve structure is a device used to adjust the air volume in the ventilation system. By controlling the opening and closing degree of the air door, the ventilation air volume adjustment and air pressure control can be achieved.

[0003] In the prior art, the air valve on the control system is generally composed of a valve body, multiple valve leaves and an actuator. Each valve leaf moves and opens and closes under the drive of the transmission structure of the top cap. When the valve leaves are completely dispersed, the air valve is closed. Because the transmission structure between the valve leaves needs to be large enough to meet the transmission requirements, there are gaps between the upper and lower valve leaves, making it difficult to achieve complete sealing, and the structure is very unstable; in the process of gradually changing the air outlet area, because too many valve leaves cannot be set in the structure, the selectable adjustment angles are too few; when the valve leaves are completely retracted, the air valve opens, and the air valve blocks one-third of the area, and the maximum air outlet area is limited.

[0004] Therefore, a wind valve structure is needed that can play a sealing role and enhance structural stability. Summary of the invention

[0005] In order to solve the above-mentioned problem, this solution provides a sealed air valve structure.

[0006] To achieve the above purpose, the technical solution adopted in this scheme is: a sealed air valve structure, including a valve body, a valve leaf assembly and an actuator, the internal retaining wing of the valve body is vertically arranged on the limiting layer, and the actuator drives the valve leaf assembly to rotate under the drive of the transmission assembly.

[0007] Further, the valve leaf assembly includes a cap sheet and six valve leaves;

[0008] The transmission assembly comprises a first transmission hole on the limiting layer, a first convex portion on the cap sheet, and a second transmission hole and a second convex portion on each valve blade.

[0009] Furthermore, the valve blades are stacked in sequence and sleeved on the shaft sleeve of the cap piece, the first protrusion of the cap piece is limited in the second transmission hole of the adjacent valve blade, the second protrusions on the remaining middle valve blades are limited in the second transmission hole of the next valve blade in sequence, and the second protrusion at the bottom of the valve blade close to the limiting layer is limited in the first transmission hole.

[0010] Furthermore, the first protrusion is arranged on one side of the shaft sleeve, and the shaft sleeve is arranged in the middle of the cap piece.

[0011] Furthermore, the first transmission hole and the first through hole are arranged in the middle of the limiting layer, and the edge includes a first mounting end.

[0012] Furthermore, the exterior of the valve body includes a wire outlet hole and second mounting ends arranged on both sides.

[0013] Furthermore, the actuator is a stepping motor.

[0014] In summary, this solution has the following advantages:

[0015] The retaining wing provided in this solution overcomes the problem in the prior art that there is a gap on the side when the valve leaf assembly is fully spread out, so that the air valve structure can be completely sealed in the closed state and the rotation angle of the valve leaf assembly is limited;

[0016] The valve leaf assembly provided in this solution reduces the shielding area of ​​each leaf and increases the ventilation area by stacking multiple layers of valve leaves. At the same time, the valve leaves are tighter and have stronger sealing properties. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0031] Embodiment 1:

[0032] A sealed air valve structure, as shown in the figure, includes a valve body 100, a valve leaf assembly 200 and an actuator.

[0033] As shown in the figure, the valve body 100 is an integrally formed, internally hollow cylinder, and is used for the limit actuator and the valve leaf assembly 200 .

[0034] It is worth mentioning that the wall thickness of the valve body 100 of this solution is smaller than that of the prior art, and the overall occupied space is smaller.

[0035] The retaining wing 110 inside the valve body 100 is vertically arranged on the limiting layer 120 , and the first limiting ring 121 on the outer periphery of the limiting layer 120 is arranged on the inner wall of the valve body 100 .

[0036] The retaining wing 110 overcomes the problem in the prior art that there are gaps on the sides when the valve leaf assembly 200 is fully spread out, so that the air valve structure can be fully sealed in the closed state and the rotation angle of the valve leaf assembly 200 is limited.

[0037] The shape of the limiting layer 120 structure is consistent with the valve leaf assembly 200, and the two sides of the circular thin plate are fan blades. The limiting layer 120 has a first through hole 122 and a first transmission hole 123 in the middle, and the edge includes a first mounting end 124.

[0038] The second mounting ends 130 are disposed on both sides of the exterior of the valve body 100 for connecting to the outer steel parts.

[0039] The outer side of the valve body 100 further includes a wire outlet hole 140 for routing the actuator wires.

[0040] The actuator acts on the valve leaf assembly 200 . In this embodiment, the actuator is a stepper motor, and the actuator end is the motor output port.

[0041] Specifically, the actuator is fixed on the first mounting end 124 through a connecting piece, and the actuator end passes through the first through hole 122; the valve leaf assembly 200 is sleeved on the actuator end, and the lowermost position of the valve leaf assembly 200 is limited to the top of the first limiting ring 121.

[0042] As shown in the figure, the valve leaf assembly 200 includes a cap plate 210 and a plurality of valve leaves 220 .

[0043] When the valve leaf assembly 200 is completely spread out, it forms a sealed state of the air valve with the limiting layer 120 of the valve body 100, thereby overcoming the problems of air leakage or structural instability.

[0044] The width of the fan blade is smaller than the limiting layer 120. When the valve leaf assembly 200 is fully gathered, one side of the fan blade fits the blocking wing 110, and the other side is longitudinally coaxial with one side of the limiting layer 120. Through such a structural setting, the shielding space of the valve leaf assembly 200 is reduced, and the air volume of the air outlet is increased.

[0045] The cap piece 210 includes a second limiting ring 211 and a first fan blade 212 . The first fan blade 212 includes a shaft sleeve 213 in the middle. The shaft sleeve 213 corresponds to the execution end. Specifically, the shaft sleeve 213 passes through the valve blade 220 and is sleeved on the execution end. A first protrusion 214 is arranged next to the shaft sleeve 213 .

[0046] The valve blade 220 includes a third limiting ring 221 and a second blade 222 , and the second blade 222 includes a second convex portion 2221 and a second transmission hole 2222 in the middle.

[0047] The linkage assembly between the valve leaf assemblies 200 provided in this solution is staggered between the holes and the protrusions, so that the valve leaf assemblies 200 are directly fitted, increasing the usable space in the valve body 100, and more valve leaves 220 can be arranged in the valve body 100;

[0048] That is, the arrangement of the valve leaf assembly 200 reduces the shielding area of ​​each leaf and increases the ventilation area by stacking multiple layers of valve leaves 220. At the same time, the valve leaves 220 are tighter and more tightly sealed.

[0049] In this embodiment, there are six valve leaves 220 , with the cap piece 210 disposed at the top and the bottom placed on the limiting layer 120 .

[0050] Specifically, the valve blades 220 are stacked and sleeved on the shaft sleeve 213 of the cap plate 210 in sequence, the first protrusion 214 of the cap plate 210 is limited in the second transmission hole 2222 of the valve blade 220 it fits, and the second protrusions 2221 on the remaining middle valve blades 220 are limited in the second transmission hole 2222 of the next valve blade 220 in sequence, and the second protrusion 2221 at the bottom of the valve blade 220 close to the limiting layer 120 is limited in the first transmission hole 123.

[0051] After the parameters of the stepper motor are set, the motor starts each time in a consistent manner. After the motor output port drives the cap piece 210 to rotate once, the valve blade 220 is linked to move once for each subsequent rotation.

[0052] Further explanation in combination with its usage mechanism:

[0053] The valve blade 220 is sleeved on the shaft sleeve 213 of the cap piece 210 and limited in the valve body 100. The bottom of the shaft sleeve 213 is connected to the motor output port of the stepping motor. The motor outputs for the first time, driving the cap piece 210 to rotate, and the first convex portion 214 at the bottom of the cap piece 210 moves in the second transmission hole 2222 of the valve blade 220 it is attached to, forming a second transmission hole 2222 edge of the valve blade 220 that ends the attachment.

[0054] The motor outputs for the second time, and the first protrusion 214 at the bottom of the cap piece 210 drives the valve blade 220 to move through the second transmission hole 2222 of the valve blade 220 it fits. Next, the motor drives the cap piece 210 to rotate in turn with the second protrusion 2221 of the valve blade 220 below until the valve leaf assembly 200 is fully opened, thus completing the process.

[0055] In the reverse rotation, the motor drives the cap piece 210 to sequentially link the second convex portion 2221 of the valve leaf 220 below to rotate until the valve leaf assembly 200 is completely closed, and the formation is completed.

[0056] In summary, the retaining wing provided by the present application overcomes the problem in the prior art that there is a gap on the side when the valve leaf assembly 200 is fully spread out, so that the air valve structure can be completely sealed in the closed state and the rotation angle of the valve leaf assembly is limited;

[0057] The valve leaf assembly provided in the present application reduces the obstruction area of ​​each leaf and increases the ventilation area by stacking multiple layers of valve leaves. At the same time, the valve leaves are tighter and more tightly sealed.
